The invention provides pharmaceutical compositions, methods for the treatment, and diagnostics and computer-implementable systems that relate to the treatment of an array of the manifestations of metabolic syndromes, including Type 2 diabetes, hyperlipidemia, weight gain, obesity, insulin resistance, hypertension, atherosclerosis, fatty liver diseases and certain chronic inflammatory states that lead to these manifestations. In an additional aspect of the invention, compositions and methods of treatment-(which may entail concomitant pharmacological and surgical intervention e.g. Roux-en-Y gastric bypass (RYGB)) activate the ileal brake, which acts in the gastrointestinal tract and the liver of a mammal to control metabolic syndrome manifestations and thereby reverse or ameliorate the cardiovascular damage (atherosclerosis, hypertension, lipid accumulation, and the like) resulting from progression of metabolic syndrome.
In other aspects, the invention provides compositions, methods of treatment, diagnostics, and related systems useful in stabilizing blood glucose and insulin levels, control of hyperlipidemia, control of inflammation in organs tissues and blood vessel walls and treating gastrointestinal disorders.
Thus, the invention provides methods of treatment and pharmaceutical compositions that can be used to prevent, reduce the likelihood of, or delay the onset of, a metabolic syndrome in art obese but otherwise healthy subject, can also be used to treat obese subjects who suffer from one or move metabolic syndromes or consequences thereof. One aspect of the invention teaches that a novel formulation of glucose in dosages of approximately 10 grams or less per day, has both short and long term beneficial effects on patients with Type 2 diabetes. Glucose is normally considered to be damaging to Type 2 diabetes, so it is very novel to use small amounts of specially formulated glucose, applied to a distal location of the intestine by the unique release properties of this formulation, to ameliorate not only the hyperglycemic manifestations of Type 2 diabetes, but also to control the entire associated metabolic syndrome that begins with obesity in the pre-diabetic phase of the disease. This invented medicament can lower their insulin resistance, lower triglycerides, reduce body weight, reduce HBA1c, and lower chronic inflammation, all in the manner of RYGB surgery, whose teachings gave insight into the discovery of this medicament. By means of careful study of enabling biomarker studies, it was apparent that said medicament acts on the same anatomical location and produces the same biochemical pathways as RYGB surgery, the biological target of both being the L-cells of the ileum and distal intestine.
In certain embodiments, the present invention relates to compositions and methods useful for selective modulation of appetite in the manner of RYGB surgery. For example, the present invention also relates to ileal brake hormone releasing substances, and more specifically to the discovery and use of an oral formulation of ileal brake hormone releasing substances which contain a combination of naturally occurring substances which are particularly adapted to treating non insulin dependent diabetes mellitus, pre-diabetic symptoms, insulin resistance and related disease states and conditions of the gastrointestinal tract, diagnostic applications and biological transport of medicaments. Accordingly, the present invention, also relates to methods of using a novel formulation for the treatment of disease states, disorders and/or conditions, or manifestations of metabolic syndrome. It should be added that there is no single treatment for metabolic syndrome in all of its manifestations, while both RYGB and the Brake formulation encompass the widest array of beneficial treatment tints tar discovered.
In one embodiment, the present invention is directed to a method of enhancing the regeneration or remodeling of target organs and tissues of patients with metabolic syndrome disease in need, wherein the treatment is oral mimicry of RYGB actions which thereby produces the endogenous process of regeneration or remodeling of target organs and tissues. In one embodiment, the present invention is directed to a method of enhancing the regeneration or remodeling of target organs and tissues of patients with metabolic syndrome disease in need thereof, wherein the primary treatment is a cell transplant or a stem cell transplant or graft of cells and/or tissue, wherein said method enhances the implanted cells or tissues by oral mimicry of RYGB actions according to the methods otherwise disclosed herein.
One of the factors thought to act as a result of activation of the ileal brake is glucagon-like peptide-1 (7-36) amide (GLP-1), which is processed from proglucagon throughout the small bowel and in the distal small bowel (ileum), and to a lesser extent in the ascending colon, as well as in the central nervous system. GLP-1 has powerful actions on the gastrointestinal tract. Infused in physiological amounts, GLP-1 potently inhibits pentagastrin-induced as well as meal-induced gastric acid secretion. It also inhibits gastric emptying rate and pancreatic enzyme secretion. Similar inhibitory effects on gastric and pancreatic secretion and motility may be elicited in humans upon perfusion of the ileum with carbohydrate- or lipid-containing solutions. Concomitantly, GLP-1 secretion is greatly stimulated during intestinal perfusion experiments, and it has been speculated that GLP-1 may be at least partly responsible for this so-called “ileal-brake” effect.
Within the central nervous system, GLP-1 has a satiating effect, since administration of GLP-1 into the third cerebral ventricle reduces short-term food intake (and meal size). while administration of GLP-1 antagonists have the opposite effect. The administration of graded doses of human GLP-1 produced plasma GLP-1 concentrations within physiological ranges and resulted in the reduction of intake of food in non-obese, healthy male subjects.
GLP-1 is formed and secreted in parallel in the intestinal mucosa along with glicentin (corresponding to PG (1 69), with the glucagon sequence occupying residues Nos. 33 61); small amounts of C-terminally glycine-extended but equally bioactive GLP-1 (737), (PG (78 108)); intervening peptide-2 (PG (111 122) amide); and GLP-2 (PG (126 158)). A fraction of glicentin is cleaved further into GRPP (PG (1 30)) and oxyntomodulin (PG (33 69)).
GLP-1 is also effective in selectively stimulating insulin secretion in patients when the blood glucose is ≥90 mg/dl. Thus, it has the advantage of lowering blood glucose primarily during the prandial phase and does not carry the risk of hypoglycemia if administered without insulin or secretagogues. Additionally, through action at the pancreatic alpha-cells it potently inhibits the inappropriate glucagon secretion seen in Type 2 diabetes. Because of these actions it has pronounced blood glucose lowering effects, particularly in patients with Type 2 diabetes. Byetta® (exenatide) is an incretin mimetic and a GLP-1 receptor agonist, the advantage being a longer half-life in the body compared to native GLP-1. Administered subcutaneously. Byetta® mimics the actions of GLP-1 that occur naturally in the gastrointestinal tract and has emerged as an efficacious type 2 (non-insulin-dependent) diabetes therapy adjunct to one or more oral hypoglycemic agents. While there is general consensus that GLP-1 agonists are partially responsible for the actions of the ileal brake on satiety, it has been controversial whether GLP-1 is responsible for the beneficial actions of RYGB on weight loss, and in fact peripheral administration of GLP-1 agonists like Byetta (exenatide) and Victoza (liraglutide) are associated with modest weight loss (3-5 kg) that occurs slowly over months of treatment RYGB associated weight loss occurs more rapidly, and is associated with a marked decline in insulin and insulin resistance, the magnitude of which is not seen when GLP-1 is administered peripherally to patients with Type 2 diabetes. Some studies argue that calorie restriction alone can produce weight loss. (Isbell J M, Diabetes Care 2010; 33; 1438-1442). In their obese subjects, calorie restriction alone reduces weight over a very short period, but does not elevate GLP-1, or increase the 1st phase insulin response to the meal, or decrease Ghrelin to the extent of RYGB. Thus, there is a controversial interpretation of the real effect of RYGB on body weight and Type 2 diabetes. None the less, it is argued that approximately 80% of type 2 diabetic patients who have RYGB surgery resolve their diabetes and insulin resistance even before they begin losing weight. The RYGB patients in these studies have elevations in GLP-1 to values not seen if they undergo caloric restriction alone. This and other discoveries led to the use of exogenous GLP-1 agonists as drugs to treat Type 2 diabetes, and several of these are on the market or in final stages of approval. In spite of their beneficial impact on Type 2 diabetes, the marketed GLP-1 agonists such as Byetta (exenatide) and Victoza (liraglutide) do not produce all of the beneficial actions that can cure type 2 diabetes, and the recent trend is to treat Type 2 diabetes with combinations of Insulin and GLP-1 agonists.
Peripherally injected GLP-1 drugs do not cure Type 2 diabetes in obese patients, while RYGB cures 80% of these same patients. So, it has been proposed that there are other effects of RYGB beyond GLP-1 and even beyond caloric restriction in combination with peripheral GLP-1 agonists. To this point in the work, there has not been a means of mimicry of the entire spectrum of effects of RYGB that can be observed, in patients who undergo the procedure and lose weight. It is believed from the improved response above and beyond that of exogenous GLP-1 alone, that there are additional endogenous substances that must be involved in bringing the body into weight and metabolic balance and resolving type 2 diabetes, but until the present invention of an oral mimetic of RYGB, these have not been advanced into practice. In fact, although there is marked improvement in HBA1c with GLP-1 agonists, metabolic syndrome complications of hyperlipidemia, atherosclerosis and inflammation are not as effectively treated, or completely resolved, by administration of GLP-1 substances as drugs in comparison to RYGB. GLP-1 drugs are not yet approved for, nor marketed as weight loss products. By contrast, surgical treatment of the type 2 diabetes patient with Roux-en-Y gastric bypass (RYGB) produces all of the beneficial effects on patients with type 2 diabetes AND weight loss and control of the manifestations of metabolic syndrome, and is increasingly viewed by physicians as curative of the entire spectrum of manifestations associated with metabolic syndrome. This leads to the completely novel idea that metabolic syndrome manifestations have a single root cause and RYGB mimicry would become a single treatment for all the manifestations. It therefore became necessary to invent a means to mimic all of the actions of RYGB to produce beneficial action on aspects of metabolic syndrome not controlled by GLP-1 agonists or any of the other available medicaments alone. We disclose herein a formulation and method of use to treat all of these manifestations of metabolic syndrome with a single oral treatment, in a dosage that will be generally free of adverse effects.
Peptide YY (PYY), a 36-amino-acid peptide, is secreted primarily from L-cells residing in the intestinal mucosa of the ileum and large intestine. PYY, which belongs to a family of peptides including neuropeptide Y (NPY) and pancreatic polypeptide, is released into the circulation as PYY (PYY (1-36) and PYY(PYY (3-36); the latter is the major form of PYY in gut mucosal endocrine cells and throughout the circulation. Plasma PYY levels begin to rise within fifteen minutes after the ingestion of food, plateau within approximately ninety minutes, and remain elevated for up to six hours. Exogenous administration of PYY (PYY (3-36) reduces energy intake and body weight in both humans and animals. Via Y2 receptors, the satiety signal mediated by PYY inhibits NPY neurons and activates pro-opiomelanocortin neurons within the hypothalamic arcuate nucleus. Peripheral PYY (PYY 3-36) binds Y2 receptors on vagal afferent, terminals to transmit the satiety signal to the brain. There are studies that imply a beneficial effect of PYY in combination with GLP-1 in animal models of weight loss. There also exist studies that demonstrate the desire for food and the sense of taste change significantly following RYGB. This is likely related to orchestra of gut-derived hormonal and signaling changes following the procedure. The bulk of evidence favors benefit to the PYY elevations that follow RYGB surgery, and to an oral formulation that would mimic this effect as well.
Insulin is the principal hormone responsible for the control of glucose metabolism. It is synthesized in the β cells of the islets of Langerhans as the precursor, proinsulin, which is processed to form C-peptide and insulin, and both are secreted in equimolar amounts into the portal circulation. Insulin has been used for treatment of diabetes for many years and is lifesaving for patients with Type 1 diabetes, where the impact of replacing deficiency of pancreatic insulin with peripheral insulin is beyond doubt. The value of additional insulin to the Type 2 diabetes patient, who already secretes large amounts of insulin, is less clear although most physicians use insulin when oral treatments do not control blood glucose. It is very interesting and perhaps counter-intuitive that RYGB cures type 2 diabetes and does so by lowering both insulin and glucose levels, producing a rapid decline in insulin resistance by HOMA-IR measurements. This decline in insulin resistance is associated with very early resolution of Type 2 diabetes, before meaningful weight loss. Type 2 diabetes patients who undergo RYGB surgery are off their insulin within a few days of surgery, before they have lost significant amounts of weight. Clearly, the unique RYGB cure of Type 2 diabetes does not require more insulin, in fact it appears to require much less, including cessation of both basal and prandial peripheral insulin requirements within a few (lays of RYGB.
It may be asked why RYGB surgery produces such a novel effect on not only Type 2 diabetes but also on the protean manifestations of metabolic syndrome, even before die RYGB patient has any significant weight loss. The discovery was associated with the controlling centers in the distal intestine, which are termed the L-cells. The actions of the L-cells have been used to describe a pathway biomarker pathway to resolution of Type 2 diabetes and metabolic syndromes, and the pathway in general has been called the Ileal Brake. The original description of the ileal brake was physiological, and at the time not much was known of the various biomediators of its action. It was not anticipated that the ileal brake controlled the onset or resolution of Type 2 diabetes or metabolic syndrome. Furthermore, there was no need to evoke the ileal brake as a means of curing metabolic syndromes because at the time we were all focused on treating glucose elevations, lipid elevations, and heart attacks as caused by clots in coronary arteries. So, the discovery of an ileal brake sensor received little attention except to catalyze commercialization of GLP-1 agonists. The ileal brake was not considered important because GLP-1 drugs were administered peripherally and there was no need to evoke a GI-pancreas-Liver explanation for progression of Type 2 diabetes. There was no need to evoke a metabolic syndrome discussion because we were satisfied treating each manifestation as a separate disease. There was no need to consider a GI hormone regulatory pathway for the use of GLP-1 peripherally, it was only when RYGB effects could not be explained beyond the weightless effect that we sought an explanation for the cure of Type 2 diabetes. We discovered the key role of the distal ileum of the GI tract. It was these discoveries that led to the new understanding that RYGB was a common solution for all of the manifestations of metabolic syndrome, and it was very surprising to link them to the rapid resolution of insulin resistance, indeed which occurred within days of RYGB surgery. Furthermore, mimicry of the entire spectrum of actions of RYGB on the ileal Brake with an oral formulation is very novel, although we refer to it in the course of the invention of the Supply Side Model.
Oral mimicry of the ileal brake pathways as discovered by RYGB surgery has now been studied in patients as disclosed herein. Oral formulations targeting the ileal brake offer a fresh approach to the treatment of Type 2 diabetes, obesity and other metabolic syndrome manifestations. It is the best means of oral mimicry of the resolution of Type 2 diabetes after RYGB. With regard to the impact of RYGB on Type 2 diabetes, we proposed a Supply Side model to describe Type 2 diabetes progression from the ingestion of glucose load to the impact of various oral treatments and insulin on the cardiovascular complications that are so common in Type 2 diabetes. The Supply Side Model of Type 2 diabetes, and the system involved in discovery of the impact of the ileal brake on Type 2 diabetes was first disclosed in US20110097807A2, which is incorporated by reference in its entirety here wherein there was clearly an impact of glucose supply on the progression of Type 2 diabetes, a beneficial effect of RYGB on Type 2 diabetes, and for the first time it was proposed to treat Type 2 diabetes with small amounts of precisely formulated glucose via actions on the ileal brake in the same manner as RYGB surgery. In the Supply Side Model, the most beneficial approach to treatment of Type 2 diabetes and its complications was RYGB surgery, while the second most active approach to Type 2 diabetes was an oral formulation of a small amount of glucose applied to the ileal brake alone or in combination with currently available anti-diabetes drugs such as DPP-IV inhibitors.
There has been other work on the ileal brake response to stimulation. For example, U.S. Pat. Nos. 5,753,253 and 6,267,988 disclosed that since satiety feedback from die ileum is more intense per amount of sensed nutrient than from proximal bowel (jejunum), timing the release of a satiety-inducing agent to predominate in ileum will also enhance the satiety response per amount of agent ingested. Thus, both the spread and predominant site of delivery (ileum) will maximize the effect, so that a small amount of released nutrient will be sensed as though it were a large amount, creating a high satiating effect U.S. Pat. Nos. 5,753,253 and 6,267,988 disclose administration of a satiety-inducing agent with a meal and at a time of around 4-6 hours before rite next scheduled meal.
U.S. Pat. No. 7,081,239 discloses manipulating the rate of upper gastrointestinal transit of a substance in a mammal, as well as methods of manipulating satiety and post-prandial pyramidal visceral blood flow. The methods of treatment disclosed in U.S. Pat. No. 7,081,239 can be administered up to a period of 24 hours prior to ingestion of the food, nutrient and/or drug, but most preferably are administered between about 60 to 5 minutes before ingestion. U.S. Pat. No. 7,081,239 notes that in prolonged treatment of postprandial diarrhea or intestinal dumping, there is at least a potential for an adaptive sensory feedback-response that can allow treatment to be discontinued for a number of days without a recurrence of the disorders.
Despite the aforementioned knowledge regarding the role of ileal hormones in digestion and insulin secretion, the need continues to exist for improved therapies that harness the additional anti-metabolic syndrome aspects of the “ileal-brake” effect, beyond the limited exploitation of the peripheral administration of GLP-1 and/or insulin pathway to treat or prevent the onset of Type 2 diabetes or obesity-related disorders. There Ls increasing evidence that the action of the ileal brake is beyond satiety, and more specifically, the regulation of digestion related inflammation is a novel effect of the ileal brake. This pathway is a new explanation for metabolic syndrome manifestations inducting but not limited to progressive obesity and the complications of type 2 diabetes in humans. The growing prevalence of type 2 diabetes, obesity and obesity-related disorders makes this need particularly acute.
Type 2, or noninsulin-dependent diabetes mellitus (NIDDM) typically develops in adulthood. Type 2 diabetes is associated with resistance of glucose-utilizing tissues like adipose tissue, muscle, and liver, to the actions of insulin. Initially, the pancreatic islet beta cells compensate by secreting excess insulin. Eventual islet failure results in decompensation mid chronic hyperglycemia. Conversely, moderate islet insufficiency can precede or coincide with peripheral insulin resistance.
There are several classes of drugs that are useful for treatment of Type 2 diabetes: 1) alpha-glucosidase inhibitors which block and delay carbohydrate absorption, 2). Bile acid sequestrates that ace thought to diminish hepatic gluconeogenesis, 3) basal insulin secretagogues (sulfonylureas), which directly stimulate insulin release, carrying the risk of hypoglycemia; 4) prandial insulin secretagogues (meglitinides) which potentiate glucose-induced insulin secretion, and must be taken before each meal, and also carry risk of hypoglycemia; 5) biguanides, including metformin, which attenuate hepatic gluconeogenesis (which is paradoxically elevated in diabetes); 6) insulin sensitizers, for example the thiazolidinedione derivatives rosiglitazone and pioglitazone, which improve peripheral responsiveness to insulin, but which have side effects like weight gain, edema, and occasional liver toxicity; 7) Dopamine agonists which are drought to reduce hypothalamic dopaminergic tone and insulin resistance; 8) DPP-IV inhibitors which are responsible for the breakdown of DPP-IV, the principle enzyme responsible for GLP-1 degradation; 9) GLP-1 mimetics which are peripherally administered replacements for GLP-1, as noted above; 10) Amylinomimetics which are peripherally administered replacements of amylin, a neuroendocrine hormone cosecreted with insulin by the β-cells that slows gastric emptying, suppresses post-prandial glucagon secretion, and centrally modulates appetite) 11) basal and bolus insulin injections, which may be necessary in the later stages of Type 2 diabetes when the islets have either failed or lay dormant under chronic hyperstimulation.
Insulin resistance can also occur without marked hyperglycemia, and is generally associated with atherosclerosis, obesity, hyperlipidemia, and essential hypertension. This cluster of abnormalities constitutes the “metabolic syndrome” or “insulin resistance syndrome”. Insulin resistance is also associated with fatty liver, which can progress to chronic inflammation, nonalcoholic steatohepatitis, fibrosis, and cirrhosis. Cumulatively, insulin resistance syndromes, including but not limited to diabetes, underlies many of the major causes of morbidity and death of people over age 40.
The present understanding and treatment of metabolic syndrome is highly fragmented, with the choice of one or more popular medications for each of its components. There are drugs for each manifestation that treat only lit at particular biochemical aspect, (such as diabetes drugs for glucose, lipid control drugs for hyperlipidemia, obesity drugs for weight control, and the like). Surprisingly, there are currently no modern approaches to treat all of the manifestations of metabolic syndrome as a unit or constellation. Because each of the available treatments has certain disadvantages and some reverse the beneficial effects of others, indeed it was a novel approach to find a treatment for all of these manifestations with a single oral medicament, and it was even more surprising to discover that the home for metabolic syndromes was the supply of glucose and the controller was the ileal brake. Thus metabolic syndromes of all types could be viewed holistically, with a common source, controllers in place that regulate many aspects of glucose supply in diet, clear links to other nutritional components, and once again a curative surgical procedure (RYGB) that points to the actions of oral treatments designed to mimic its actions on the L-cells in the distal small bowel. Stimulation of these cells, which grow tolerant to dietary glucose overload, wakes up the ileal brake and re-balances the Supply of Nutrients and thus insulin demand pathways disclosed in U.S. Ser. No. 12/911,497 filed Oct. 25, 2010; Published as US 2011/097807 A1 on Apr. 28, 2011, which is incorporated by reference herein.
The gastrointestinal tract is not heretofore known as the primary driver of metabolic syndrome, even though it is possible to account for inflammation, obesity, hyperlipidemia and fatty liver disease arising all from the interaction between the gastrointestinal tract, the pancreas and the liver. Indeed there is evidence that the metabolic syndrome symptomotology begins with dietary components such as glucose, according to the teachings of the supply side model of diabetes as disclosed in United States patent application publication no. US2011/0097807-A1 published Apr. 28, 2011, which is incorporated by reference herein. Drugs acting directly on the ileal brake of the GI tract are highly active against the entire spectrum of metabolic syndrome manifestations, but in particular those that are associated with insulin resistance as an early manifestation. Examples would be pre-diabetes, obesity, and triglyceride dominant hyperlipidemia. In these conditions the glucose load is the primary driver of insulin resistance, and the defect that leads to obesity is the down regulation of the L-cell response to increasing dietary glucose. The body does not reject more glucose in the diet as the L-cells are down regulated, but this increasing dietary supply leads to the need to store the excess as fat. Insulin resistance is the first systemic manifestation of increasing glucose load and down regulation of the ileal brake. It is die purpose of the present application to disclose in detail a formulation and method for treatment of the entire array of man infestations of metabolic syndrome drat are linked to increasing insulin resistance, thereby obviating the long term inflammatory and vascular complications such as morbid obesity, atherosclerosis, myocardial infarction, stroke and later stages of Type 2 diabetes that involve loss of pancreatic ability to secrete insulin. RYGB surgery restores the homeostasis and these manifestations are avoided or at least delayed in onset. Accordingly, formulations and compositions are disclosed that treat all of the major manifestations of insulin resistance, tatty liver diseases, increased triglycerides and other lipids, and obesity.
Despite the existence of various anti-diabetes and glucose control drugs, diabetes remains a major and growing public health problem. Even more concerning recent large-scale randomized controlled trials (ACCORD, ADVANCE, VADT) have created confusion with respect to the proper glucose target because of contradictory data on major cardiovascular events when lowering the glucose too aggressively through algorithms that favor aggressive intensification strategies with secretagogues and insulin. Therein, the problems of hypoglycemia and weight gain inherent to secretagogues and insulin were confounding to any benefits of blood glucose lowering. No clear data exist to determine if preferential treatment with weight neutral or gut hormone-based regimens (i.e. GLP-1) would have resulted in clear improvements in both microvascular and macrovascular complications. Long-term randomized clinical trial evidence demonstrating that treating with GLP-1 agonists yield improved cardiovascular benefits would lend significant credence to the concept that treating with an agent that corrects multiple physiologic hormone signals would not only benefit the management of blood glucose, but the overall cardiovascular status. Similar to Type 2 diabetes, despite many lipid lowering drugs, vascular disease continues to increase in scope and the number of patients with complications also increases. Obesity is increasing rapidly in-spite of weight loss foods and stimulatory drugs. What are needed are not necessarily new drug therapies, which often are accompanied by significant side effects, but rather a method of treatment as an alternative or supplement that addresses the underlying metabolic syndrome and associated insulin resistance. Because it is known that all of the metabolic syndrome man infestations are ameliorated by RYGB surgery, it was desirous to produce each and all of these beneficial events by evoking the mechanistic pathway involved in the reduction of metabolic syndrome by RYGB surgery. Because this mechanistic pathway has recently been discovered by the inventors, it was soon possible to create an orally available formulation of the same substances that produce beneficial actions in the mimicry of RYGB action on the ileal brake. Indeed both of these produce beneficial actions on metabolic syndrome by activation of the ileal brake, which is primarily located in the distal small intestine in the ileum. The formulation that is active, called Brake or Aphoeline in some configurations is a unique combination of natural substances which are food components such as lipids and simple sugars (e.g. mono- and disaccharides, preferably glucose or dextrose). Most of these substances have been listed as GRAS (Generally Regarded As Safe) substances, which after specific formulation for release at the ileum, may be administered as an ileal brake hormone releasing substance, and target the dietary associated inflammatory condition which leads to metabolic syndrome and its consequences. There is a particular need to provide a new orally active approach to treatment of all of the manifestations of metabolic syndrome, which effectively addresses the primary defects of inflammation, obesity, insulin resistance and hyperlipidemia without side effects, so that the therapeutic substance can be administered to those who are in the pre-diabetic stages, or who exhibit pre-diabetic symptoms, so as to forestall or preclude the onset of type 2 diabetes or other complications of metabolic syndrome. It is much easier to resolve obesity and insulin resistance early with an oral formulation, and this would place the use of RYGB later in the course of the disease where more dramatic procedures are easier to justify.
When glucose is absorbed from the early portion of the duodenum, the glucose quickly reaches the beta cells of the pancreas and enters these pancreatic cells via the glut 2 glucose transporter. The amount of glucose in the blood plasma is directly proportional to the glucose being transported into the beta cells.
When insulin is released into the body, it exerts an effect at the cellular level throughout the entire body, but more specifically in the liver, the muscle tissues, and the fat or adipose tissues. The effects can occur in a “short acting” way that stimulates the glucose uptake in muscles and fat cells, thereby increasing the synthesis of glycogen in muscle and liver, inhibiting glucose secretion in the liver, and increasing amino acid uptake, or in a “long term” way which increases protein synthesis and stimulates certain gene expression in all cells. Insulin works by binding with insulin receptors on a cell surface. Once coupled, kinase enzymes push glut 4, the major glucose transport receptor, to attach to the cell surface for driving the glucose intracellularly.
It is generally known that the surface of muscles and fat cells have other receptors that can drive the glucose intracellularly without insulin. These receptors work with IGF-1 and IGF-2 hormones. There is also believed to be an undefined IRR receptor structurally similar to the receptors working with IGF-1 and IGF-2 hormones located on the cell surface but die correlating hormone has not yet been found. In general, the body should maintain a substantial equilibrium, that is, the amount of insulin secreted should be equal to the amount of insulin needed to keep the blood glucose level steady.
One problem that can be experienced is when insulin is not being adequately produced, typically because the pancreas, and mom specifically the beta cells, have been destroyed or are devitalized, as typically seen in Type 1 diabetes, where the output of insulin is decreased or absent. A second problem is where insulin interactions, that is between the insulin, the insulin receptors, and the cells, are hindered by a multitude of cellular and inflammatory factors so that the action is not an efficient use of the insulin available, and as a result, much more insulin is needed to achieve the same goal of driving the glucose intracellularly. This latter condition is far more common and it is currently termed Type 2 diabetes based on the observation that there is no lack of available insulin in the body. It is this type of insulin inefficiency that the present method and composition are directed to. Insulin resistance or insulin insensitivity encompasses the majority of the population dealing with diabetes; Type A, a genetic defect of the insulin receptors (i.e., leprechaunism, Rabson Mendhall syndrome, and lipodystrophy); Type B, an autoimmune type with an antibody to the insulin receptors; and Type 2, a post membrane receptor resistance, that includes the metabolic syndrome manifestations of obesity, hypertension, non insulin dependent diabetes, aging, and polycystic ovary syndrome.
The commonly accepted theory for these two types of insulin resistant afflictions is that the glucoses are not being transported into the cells due to an autoimmune antibody (Type B) or some sort of post receptor resistance. As a result, glucoses outside of the cells build up. The pancreas, attempting to equilibrate the level of glucose and insulin, causes insulin production to increase. Even though more insulin is being produced, glucose is not being transported into the cells. Initially, the increase in insulin is capable of overcoming die insulin resistance but this requires a much higher level of insulin production. This stage is considered the pre-diabetic stage where insulin is high but glucose is normal. Ultimately, the pancreas is not capable of keeping up with the high insulin and precursor proinsulin production rate that is required, thereafter causing the glucose levels to spike, with the person eventually becoming officially classified as diabetic.
The common non-invasive treatment for diabetics is to start and maintain a proper diet and exercise routine. Second, doctors may prescribe medication such as (i) sulfonylureas to stimulate additional secretion of insulin, which can speed up the exhaustion of the pancreas; (ii) metformin may be prescribed to improve the efficiency of insulin action and also improve on the clearance of glucose in liver and peripheral tissues, therefore decreasing the level of glucose and insulin as well.
While pre-di abetics have been treated at times with the same medications, the side effects of rite medications made it difficult for the patient to improve their health since the foregoing treatments were designed for full diabetics. In other circumstances, the medications that may produce weight loss (i.e. exenatide, liraglutide) are not permitted for the management of pre-diabetes or obesity.
The present invention relates inter alia to the following oral formulations and methods and provides the following objectives;

The integrated approach to these types of metabolic syndromes uses a single agent oral treatment that re-awakens the responsiveness of the endogenous ileal brake in obese patients wherein it is in a quiescent state. Thereby, one oral treatment can be offered for the full range of manifestations of metabolic syndromes including insulin resistance, hyperlipidemia, weight gain, obesity, hypertension, atherosclerosis, fatty liver diseases and certain chronic inflammatory states, wherein said oral treatment method comprises: testing of biomarkers; testing of breath, blood or body fluid biomarkers and selection of pharmaceutical compositions to resolve one or more of the metabolic syndrome conditions including but not limited to chronic inflammatory states, hyperlipidemia, weight gain, obesity, insulin resistance, hypertension, atherosclerosis, and fatty liver. These methods of treatment and compositions can entail personalized treatments and can use the results of biomarker testing such as HBA1c, glucose, GLP-1, PYY, GLP-2, Proinsulin, CRP, hsCRP, triglycerides, oxyntomodulin, endotoxin, IL-6. All of these biomarkers are affected by the novel treatment used for metabolic syndrome manifestations, and all are affected by RYGB surgery. Testing thus far establishes a ratio of potency between said oral medicament and RYGB. Notably, these personalized treatment and pharmaceutical compositions can be selected using a Glucose Supply Side computerized algorithm and system, wherein said Glucose Supply Side treatment method for diabetes consists of an algorithm (incorporated herein in its entirety) ranking favorable attributes of pharmaceutical compositions acting by minimizing excess glucose inside cells, and minimizing the amount of glucose that reaches target cells of the metabolic syndrome afflicted patient. The supply side algorithm provides for novel combinations of treatments including oral stimulation of the ileal brake hormones with a specifically formulated composition. It further provides for combination of the composition acting on ileal brake hormones with drugs that act on glucose, lipids, inflammation, blood pressure, obesity and other manifestations of the metabolic syndrome that afflicts the patient. More specifically, the invention claims the same or lower dose of statin products plus Brake for lipid control, the same or lower dose of DPP-IV inhibitors plus Brake for glucose control, and the same or lower doses of anti-obesity drugs such as lorcaserin for weight control.
In certain aspects, the aforementioned personalized treatments and pharmaceutical compositions may be selected by comparison of biomarker behavior patterns between patients' response to Roux-en-Y bariatric surgery and their response to oral dosing with pharmaceutical formulations comprised of sugars, lipids or amino acids which activate the ileal brake response of the ileum in a manner similar to RYGB surgery.
Significantly, the present invention provides a formulation and a drug delivery strategy that mimics the surgical re-alignment of the intestines to deliver food component substances to distal locations of the intestine. For example, in certain embodiments, RYGB Surgery and an orally administered pharmaceutical composition of the invention produce substantially the same effects on the ileal brake, even with respect to subtle and unexpected aspects like a rapid reduction in insulin resistance and regulation of the gut driven inflammation. In a purely illustrative example, an orally administered dosage of approximately 2 to 1.0 grams, about 2.5-3 to 10 grams, about-7.5 to about 10 grams, preferably 10 grams of active ingredient of a pharmaceutical composition of the invention can have an aggregate positive effect on ileal brake parameters equal to approximately 25% to approximately 80% or more of the aggregate positive effect on such parameters realized by RYGB Surgery. It is notable that these actions far exceed the action of GLP-1 given separately, and dearly evoke different and additional mechanisms and pathways for complete action against metabolic syndromes of type 2 diabetes and other associated conditions. The oral medicament will mimic the beneficial aspects of the ileal brake in the same manner as RYGB, but it will not be associated with loss of as much weight as RYGB. That is because RYGB surgery decreases the size of the stomach and thereby limits intake of food by a second, profoundly important pathway.
Thus, in one embodiment, the invention provides a method of treatment comprising administering to a subject in need thereof an ileum hormone-stimulating amount of an ileal brake hormone releasing substance which releases In vivo substantially in the subject's ileum, wherein (1) the subject suffers from, or is at risk of developing, a metabolic syndrome selected from the group consisting of hyperlipidemia, weight gain, obesity, insulin resistance, hypertension, atherosclerosis, fatty liver diseases and certain chronic inflammatory states (2) optionally, prior to or concurrent with administration, the concentration of one or more of the subject's metabolic syndrome biomarkers is measured and the ileal brake hormone releasing substance or dosage of ileal brake hormone releasing substance is selected based on the biomarker level, and (3) wherein the ileal brake hormone releasing substance comprises at least one microencapsulated glucose, lipid, or amino acid and activates the subject's ileal brake in the manner of RYGB surgery.
Orally administered pharmaceutical compositions of the invention mimic the full range of actions of RYGB surgery on the ileal brake. Mimicry of all of the actions of the ileal brake in this manner using compositions and methods according to the present invention are able to substantially inhibit and in many cases actually cure many patients of their Type 2 diabetes. It is clear that unexpected and surprising benefits of the present invention occur in the control of atherosclerosis, fatty liver, obesity, and many other chronic inflammatory states that are characteristic of metabolic syndromes in the developed world, liven more specifically, the formulation for treatment of metabolic syndrome comprises the micro-encapsulation of glucose, lipids and components of diet formulated to release these active compositions at pH values between about 6.8 and about 7.5, which allows substantial release and targets the action of said medicaments at the ileal brake in the distal intestine. Conventional formulation strategies used for pharmaceuticals never target release at pH values above 6.8. It has only been recently discovered by the inventors (using the “Smart Pill” as invented by Schentag in U.S. Pat. No. 5,279,607 herein incorporated by reference) that pH values above 7.0 are found in the GI tract, and they are characteristic of the ileum in the area ascribed to L-cells and the ileal brake. The encapsulated compositions disclosed are a preferred medicament to reduce dietary glucose associated chronic inflammation, the primary driver of metabolic syndrome and eventual development of obesity and type 2 diabetes. Use of the encapsulated compositions according to the present invention decreases appetite for glucose in the Supply Side model, beneficial to the patient with metabolic syndrome, and thereby lowers both insulin resistance and inflammation and is of benefit to the treatment of patients with metabolic syndrome, according to the results of testing of targeted biomarkers. Accordingly, methods of treatment of the invention may or may not include concomitant or even subsequent RYGB surgery, as control of metabolic syndrome in preferred practice of the invention would be possible with oral use of said medicaments, reserving RYGB surgery for cases beyond the control of said encapsulated compositions alone.
In a preferred embodiment of the invention, oral dosing with about 2,000 to about 10.000 milligrams, preferably about 3,000 to about 10,000 milligrams, about 7,500 to about 10.000 milligrams of a pharmaceutical formulation comprising microencapsulated glucoses, lipids, and/or amino acids activates the ileal brake in a dose increasing magnitude and treats one or more of the following components of metabolic syndrome: hyperlipidemia, weight gain, obesity, insulin resistance, hypertension, atherosclerosis, fatty liver diseases and chronic inflammatory states. In various embodiments according to the present invention, the disclosed formulations and compositions have been described as Aphoeline which is trademarked. Hereinafter, certain aspects of tins composition may be referred to by its trademark Brake™. Compositions of the invention may be used alone or in combination with medicaments ordinarily used to treat specific manifestations of metabolic syndromes such as diabetes, hyperlipidemia, atherosclerosis, hypertension; obesity, insulin resistance, or chronic inflammation. The benefit of Combination is a broader spectrum action for treatment of metabolic syndrome than the single agent, and additional potency of the combination over its components. For example, compositions and methods of treatment of the invention may employ co-administration of a drug such as a biguanide antihyperglycemic agent (e.g. metformin); DPP-IV inhibitors (e.g. Vildagliptin, Sitagliptin; Dutogliptin, Linagliptin and Saxagliptin); TZDs or Thiazolidinediones (which are also known to be active on PPAR), e.g. pioglitazone, rosiglitazone, Troglitazone, aleglitazar and the PPAR-sparing agents MSDC-0160, MSDC-0602; alpha glucosidase inhibitor including but not limited to acarbose (including delayed release preparations of Acarbose, Miglitol, and Voglibose); Glucokinase Activators including but not limited to TTP399 and the like; HMG-CoA reductase inhibitors, (examples of similar agents, thought to act on the defined statin pathway or by HMG-CoA reductase inhibition, include atorvastatin, simvastatin, lovastatin, cerevastatin, pravastatin pitavastatin); angiotensin 11 inhibitors (All inhibitors) (e.g. Valsartan, Olmesartan, Candesartan, Irbesartan, losartan, Telmisartan and the like); a phosphodiesterase type 5 inhibitor (PDE5 inhibitor) such as sildenafil (Viagra), vardenafil (Levitra) and Tadalafil (Cialis®); Anti-obesity compositions that may benefit from combination with Brake™ include Lorcaserin and Topiramate; Combinations that will act beneficially on gas tin intestinal flora include pH encapsulated pro-biotic organisms that release the live bacteria hi the ileum, at pH 7.0 to 7.4, these pH encapsulated probiotic bacteria may be combined further with treatments for irritable bowel disease such as linaclotide or even with antibiotics where the goal is to restore bacterial flora after disruption by potent antibiotic therapy.
In certain embodiments, compositions of the invention act hi the gastrointestinal tract and on the ileal brake to limit glucose supply and to lower all aspects of metabolic syndrome manifestations. Tints, the combination of Brake and a lipid lowering drug such as colesevelam acts on the lipid content of the blood in the same manner as colesevelam and Brake individually, with the potential to lower the dosage of one or both of the components because of this synergy; While illustrative, the selection of a combination including colesevelam is not meant to be exhaustive and it is readily apparent that additional Colesevelam mimetic medicaments can be added to the pharmaceutical composition without departing from the practice of oral treatments for metabolic syndrome that combine oral mimetics of Roux-en-Y surgery effects on the ileal brake in conjunction with conventional anti-diabetes medicaments of the class represented by colesevelam.
As summarized above, the invention includes the combination of Brake and a Glucose Supply Side method for the treatment of Type 2 diabetes mellitus and metabolic syndrome manifestations associated with Type 2 diabetes mellitus, wherein said Glucose Supply Side method has its primary action on the ileal brake and comprises the administration to a human or non-human mammal in need thereof of any of the pharmaceutical compositions in any combination and each in any dosage according to the results of testing of biomarkers demonstrating action of the medicaments chosen on the ileal brake. For example, the invention provides a method for the treatment of Type 2 diabetes mellitus and conditions associated with diabetes mellitus, using a Glucose Supply Side algorithm, wherein said method comprises testing of each patient for genomic markers of response to Glucose Supply Side selected pharmaceutical compositions, and then using the results of genomic testing to individualize the dosage of said compound using genomic markers of the Glucose Supply Side and of the patients individual metabolism of said composition alone or in combination with the results of the Glucose Supply Side breath test biomarkers. Such systems and methods of treatment of the invention can include an input/output (I/O) device coupled to a processor; a communication system coupled to the processor; and a medical computer program and system coupled to the processor, the medical system configured to process medical data of a user and generate processed medical information, wherein the medical data includes one or mom of anatomical data, diabetes associated biomarkers, test specimen data, biological parameters, health information of the user, wherein the processor is configured to dynamically control operations between the communication system and the medical system.
The invention also provides an analyzer coupled to xerogel-based substrates for concentration-dependent analyte detection, the analyzer including a xerogel-based sensor coupled to a processor configured to analyze the specimen and generate the processed medical information, wherein analysis of the specimen includes correlating parameters of the specimen with the medical data.
Further, the invention provides a system for providing metabolic syndrome component management, comprising: a sensor unit measuring concentrations of analytes; an interface unit; one or more processors coupled to the interface unit; a memory for storing data and instructions which, when executed by the one or more processors, causes the one or more processors to receive data associated with monitored analyte concentrations for a predetermined rime period substantially hi real time, retrieve one or more therapy profiles associated with the monitored analyte concentrations, and generate one or more modifications to the retrieved one or more therapy profiles based on the data associated with the monitored analyte concentrations.
In alternative embodiments, the inventors have discovered that the once-daily administration, preferably once-daily administration of an ileum-targeting, delayed and/or controlled release dosage form containing an ileal brake hormone releasing substance to a fasting subject—at a time of around four and one-half to around ten to twelve hours, preferably around six to around nine hours prior to the subject's next intended meal (most preferably at bedtime)) or in AM—produces all of the beneficial actions of the deal brake, including lowering of insulin resistance, control of glucose, and lowering of inflammation in the subject for a period of around twelve hours and preferably twenty-four hours or more (effect can be cumulative depending on the duration of taking the dosage). These beneficial actions in treatment of the manifestations of metabolic syndrome are sustained for long time periods, as present experience exceeds one year of use in some patients to be described. Alternatively, a dosage may be administered at least twice daily, preferably once before bedtime and once within the first two hours (preferably first hour) of waking. Alternatively three dosages may be administered—once in the morning, once in the afternoon and once before bedtime. While not wishing to be bound by any theory, the inventors believe that the Therapeutic substance stimulates the “ileal-brake” effect at a particularly advantageous point during a subject's feeding cycle and thereby induces the beneficial actions on type 2 diabetes and other metabolic syndromes for an extended period of time (for at least about three hours, at least about six hours, at least about twelve hours or as long as twenty-four hours or longer). Benefits continue if the medication is taken daily in proper dosage, and surprisingly, the beneficial effects persist for a period of time after the medication is stopped. Compositions and methods of treatment of the invention therefore also prove particularly useful in the treatment or prevention of overweight, overeating, obesity and obesity-related disorders, as well as the treatment of non insulin dependent diabetes mellitus, pre-diabetic symptoms, metabolic syndrome and insulin resistance, as well as disease states and conditions which occur secondary to diabetes, pre-diabetes, metabolic syndrome and insulin resistance, as well as polycystic (fibrous) ovaries, arteriosclerosis and fatty liver, as well as cirrhosis. The present methods also may be used to increase muscle mass and decrease fat in a subject.
Notably, compositions and methods of treatment of the invention modulate ileal hormone, blood insulin and glucose levels relatively consistently in a variety of tested human subjects and can therefore be used to diagnose the presence of new or established disorders related to absolute or relative deficiency or excessive secretions of one or more hormones of the ileal break, and relative response to the stimuli in the overweight or obese, or in obese related disorders or likely onset of obesity or obesity-related disorders. Compositions according to the present invention may also be used to increase blood concentrations of insulin-like growth factor I and II (IGF1 and IGF2) in a patient.
Accordingly, in one embodiment, the invention provides a method of treatment of type 2 diabetes or metabolic syndromes in a subject by once-daily administration to the subject of a delayed and/or controlled release dosage form. The dosage form is administered while the subject is in the fasted state and at a time of around six to around nine hours prior to the subject's next intended meal. The dosage form comprises an enterically-coated, ileum hormone-stimulating amount of ileal brake hormone releasing substance and releases the majority of the ileal brake hormone releasing substance in vivo upon reaching the subject's ileum.
In some embodiments as a separate effect of administration of compositions of the present invention, satiety is induced in a subject who is overweight, or suffers from obesity or an obesity-related disorder, as determined by the BMI of the subject or patient In another embodiment, the invention provides a method of treatment comprising reducing and/or stabilizing a subject's blood glucose and insulin levels, decreasing insulin resistance, by once-daily administration to the subject of a delayed and/or controlled release oral dosage form with the target site being the ileal brake. The dosage form is administered while the subject is in the fasted state and at a time of around six to around nine hours prior to the subject's next intended meal. The dosage form comprises an enterically-coated, ileum hormone-stimulating amount of ileal brake hormone releasing substance and releases the majority of the ileal brake hormone releasing substance in vivo upon reaching the subject's ileum.
In still another embodiment, the invention provides a method of treating a subject suffering from a gastrointestinal disorder by administering to the subject a delayed and/or controlled release oral dosage form comprising an enterically-coated, ileum hormone-stimulating amount of an ileal brake hormone releasing substance. The dosage form is administered while the subject is in the fasted state and at a time of around four and one-half to ten hours, more preferably around six to around nine hours prior to the subject's next intended meal. The dosage form comprises an enterically-coated, ileum hormone-stimulating amount of ileal brake hormone releasing substance and releases the majority of the ileal brake hormone releasing substance in vivo upon reaching the subject's ileum.
In still other preferred embodiments, the invention provides methods for control of metabolic syndrome and its various detrimental actions, through specific biochemical pathways that stabilize blood glucose and insulin levels, and treating gastrointestinal and hepatic inflammatory disorders comprising once-daily administration to a subject in need thereof of a delayed and/or controlled release composition which may comprise an emulsion or a microemulsion containing an ileum hormone-stimulating amount of ileal brake hormone releasing substance. The composition is administered while the subject is in the fasted state and at a time of around four to ten, preferably around six to around nine hours prior to the subject's next intended meal. The composition releases the majority of the ileal brake hormone releasing substance in vivo upon reaching the subject's ileum, the site of its intended effect.
In preferred embodiments of the aforementioned methods of treatment of the invention, the dosage form is administered once-daily at bedtime, or in AM.
By administering the dosage form to a subject in the fasted state at around four to ten, around six to around nine hours prior to the subject's next intended meal, and delivering substantially all of the ileal brake hormone releasing substance to the ileum, methods and compositions of the invention achieve improved levels of plasma gastrointestinal hormones and prove useful in the treatment or prevention of one or more of obesity, obesity-related disorders, and gastrointestinal disorders, as well as metabolic syndrome and/or type II diabetes mellitus. The benefit of obtaining at least twenty-four hour appetite suppression and improved blood glucose and insulin levels from a single oral dosage of an inexpensive ileal brake hormone releasing substance increases the likelihood that the subject will adhere to the methods of treatment for an extended time (improved patient compliance), thereby achieving a maximum health benefit. Further, compositions and methods of the invention utilize ileal brake hormone releasing substances that are free of the safety and cost concerns associated with pharmacological and surgical intervention, and can induce long-term control of appetite, inflammation, insulin resistance and hyperlipidemia.
In another embodiment, the invention provides a delayed and/or controlled release oral dosage form comprising an effective amount of an ileal brake hormone releasing substance, preferably D-glucose or dextrose in an amount effective when released in the ileum to stimulate or inhibit the release of hormones in that portion of the small intestine of a subject or patient. This dosage form is administered in accordance with, and achieves the advantages of, the aforementioned methods of treatment of the invention. In addition, die present invention provides a method for diagnosing metabolic syndrome (glucose intolerance) and/or type II diabetes in a patient or subject.
Thus, the invention provides methods of stimulating or inhibiting the hormones (depending on the hormone) of the ileum in an easy and reproducible or standardized way which did not exist prior to the present method. Pursuant to the present application, the testing on a large scale of the ileal release to study and classify the variation or pathology of the hormone releases as such release relates to control of metabolic syndromes or type 2 diabetes and related pathological states and conditions, and the effect these hormones have on the rest of the metabolic and hormonal status of the body is another aspect of the invention. Thus, the present method allows the introduction of one or more dosages in oral dosage form to the ileum of the patient which can be standardized sufficiently to allow the creation of a normal reference range for the hormonal stimulation. It has been discovered that the present invention can be used to probe different diseases stemming from the relative or absolute increase or decrease of the ileal hormones, not only in treating the overweight/obesity metabolic syndrome axis but a number of other gastrointestinal diseases as otherwise described herein.
The present method also can be used to diagnose and treat a number of gastrointestinal disorders and/or conditions which may occur as a consequence of infection, medical treatment or diseases of atrophy, including atrophic gastritis, post chemotherapy disorder, intestinal motility disorder (gut dysmobility), mild reflux, chronic pancreatitis, malnutrition, malabsorption, voluntary or involuntary long term starvation, post infectious syndrome, short bowel syndrome, irritable bowel, malabsorption, diarrheal states, post chemotherapy gastrointestinal disorder, post infectious syndrome, radiation enteritis, chronic pancreatitis, celiac disease, fatty liver disease, cirrhosis, radiation, inflammatory bowel disease and Crohn's disease, among others.
In another embodiment, the invention may be used to improve the health of the liver, improve the pancreas health, as well as the health of the intestine, and to decrease/ameliorate fatty liver, to increase the size of pancreatic beta cells (hyperplasia) in the pancreas as well as increase the size of the absorptive villae of the small bowel.
In another embodiment, the method of preparation of the pills can be used in combination with traditional bioactive agents (medication); delivery by itself or together with die core to deliver the content specifically to the ileum for targeted therapy avoiding side effects and increasing the yield of the therapy, such as specialized antibiotics, antispasmodic agents, non-specific chelating agents, antibacterial agents, probiotic bacteria that are normal components of the intestinal tract, antidiabetes agents, statin drugs, anti-obesity drugs, anti-inflammatory drugs, Crohn's disease drugs, drugs for treatment of Alzheimer's disease, drugs for treatment of multiple sclerosis, and laxatives among numerous others, including natural plant oils such as olive oil, corn oil, vegetable and animals oils, fats, such as animal fats, butter and vegetable fat, oils and fats from seeds and nuts, stimulants including caffeine, herbs, teas, ingredients that increase post receptor activities after cellular level, selected extracts or food products and chemicals, natural or otherwise, including metabolites.
In another embodiment, the invention provides a method for diagnosing metabolic syndrome (glucose intolerance) and/or type 31 diabetes in a patient the present invention approaches the problem of metabolic syndrome in a natural physiological manner by stimulating hormones in the ileum which act synergistically for a period of at least about 12 hours and preferably at least about 24 hours. It does this most preferably using natural and safe nutritional components in healthful, pleasant compositions which are preferably coated using a polymeric, preferably aqueous pH-sensitive/dissolution/release of contents of formulation occurs at a pH of the ileum, or a pH of approximately 7-8, preferably 7.2-8.0, about 7.4-8.0, about 7.5-8.0) shellac nutrateric coming to effect a natural physiological response within the subject's ileum with favorable results. The present invention represents a change in the nature of treatment for metabolic syndrome to a more wholesome, natural physiological process, completely distinguishable over pharmaceutical or synthetic approaches.
In other particular embodiments, orally administering an ileal hormone stimulating effective amount of a glucose such as dextrose or other ileal brake hormone releasing substance as otherwise described herein, optionally combined with one or more of other advantageous substances such as alfalfa leaf, chlorella algae, chlorophyllin and barley grass juice concentrate, and further formulated with a delayed release base adapted to release die composition in the lower gut, in particular the ileum, has been shown to result in normalized blood glucose and insulin levels, in particular, in subjects where there previously was shown to be an absence of elevated blood glucose but the subjects exhibited high insulin levels, that is, pre-diabetic symptoms, administering the supplement caused a decrease in insulin levels back to a normal range while glucose levels remained normal (reduced and/or stabilized). In other words, the body system achieved substantial equilibrium, with substantially no side effects reported. The result was similar to what can be achieved administering drugs such as Metaformin and IGF-1, with relatively few, if any, side effects.
Without being limited by way of theory, it is believed that by stimulating the ileal hormones contained in the lower gut, the inventive substance drives the glucose intracellularly by either (i) stimulating the production or increasing the level of IGF-1 and/or IGF-2 that will act on their own receptors, (ii) direct action on IGF-1 and/or IGF-2 receptors, or (in) stimulating one or more intestinal hormones, including a new intestinal hormone that will act on its own receptors as per the IRR receptors.
Accordingly, in another embodiment, the invention provides a method of treating noninsulin dependent diabetes mellitus, pie-diabetic symptoms, metabolic syndrome, increasing glucose tolerance and/or decreasing insulin resistance by reducing insulin levels in the bloodstream comprising administering a ileal brake hormone releasing substance composition containing an effective amount of a glucose, such its dextrose or other ileal brake hormone releasing substance as otherwise defined herein, optionally and preferably combined with one or more of alfalfa leaf, chlorella algae, chlorophyllin and barley grass juice concentrate or sodium alginate, alone or in combination with the other ingredients and further formulated with a delayed release base adapted to release the composition in the lower gut (ileum), that is, in a delayed and/or controlled release dosage form. The dosage form may comprise the ileal brake hormone releasing substance in a unit or partial dose form and have an enteric coating, including a nutrateric coating (e.g., containing shellac as a polymeric material, hypromellose, as an emulsifier, thickener and suspending agent and triacetin as an emulsifier). Alternatively, the ileal brake hormone releasing substance (preferably D-glucose or dextrose) and optionally, one or more of alfalfa leaf, chlorella algae, chlorophyllin and barley grass juice concentrate may be combined with binders, diluents, additives and other pharmaceutical additives such as one or more of a filler, compressibility enhancer (e.g., corn starch or lactose), lubricant (stearic acid), extrusion agent (magnesium stearate), silicon dioxide (dispersing agent), and enteric coated or nutrateric coated with a coating which dissolves at the pH of the ileum and includes one more polymeric components as otherwise described herein.
In another embodiment, the invention provides a method which comprises equilibrating a subject's insulin level to compliment a blood glucose level, preferably by once-daily administration to the subject of a delayed and/or controlled release oral dosage form of the invention.
In still another embodiment, the invention provides a method of treating a subject exhibiting pre-diabetic symptoms comprising administering a ileal brake hormone releasing substance composition containing an effective amount (generally, at least in part, to reduce insulin) of a glucose such as dextrose (glucose) or other ileal brake hormone releasing substance as otherwise described here, either alone, or preferably in combination with one or more of alfalfa leaf, chlorella algae, chlorophyllin and barley grass juice concentrate, in a delayed and/or controlled release dosage form, adapted to release the composition in the lower gut, the combination providing an insulin reducing effect so as to equilibrate the amount of insulin produced to correspond to the amount of blood glucose. The dosage form may comprise the ileal brake hormone releasing substance in a unit or partial dose form and having an enteric coating.
By administering the ileal brake hormone releasing substance to a person who exhibits noninsulin dependent diabetes mellitus, pre-diabetic symptoms, and/or insulin resistance, reduced levels of insulin are produced so as to avoid the “over-working” of the pancreas, thereby reducing stress on the pancreas which may forestall, for example, in someone exhibiting pre-diabetes symptoms, the onset of full blown diabetes. Thus, the present invention also has the advantage of reducing the likelihood that a patient or subject with metabolic syndrome or noninsulin dependent diabetes mellitus (type II diabetes) will see these conditions advance to insulin dependent diabetes mellitus (type 1 diabetes).
Other aspects of the invention relate to compositions which comprise an effective amount of an ileal brake hormone releasing substance as otherwise described herein, preferably glucose or dextrose which is formulated in delayed and/or controlled release dosage form in order to release an effective amount of ileal brake hormone releasing substance in the ileum of the patient or subject to whom compositions according to the present invention are administered, generally, at least 50% of the total amount of the ileal brake hormone releasing substance present, and preferably at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least, about 90%, and al least about 95% or more of the ileal brake hormone releasing substance present in the composition. In the case of D-glucose or dextrose as the ileal brake hormone releasing substance, it is preferred that at least about 2.5 grams, at least about 3 grams, at least about 7.5 grams and more preferably about 10-12.5 grams or more of glucose be released in the patients or subject's ileum in order to stimulate ileal hormone release.
Compositions according to the present invention comprise effective amounts of ileal brake hormone releasing substance, preferably Diglucose or dextrose, which may be combined with at least one delayed or controlled release component such as a delayed/controlled release polymer or compound such as a cellulosic material, including, for example, ethyl cellulose, methyl cellulose, hydroxymethylcellulose, hydroxypropylcellulose, polyvinylpyrrolidone, cellulose acetate trimellitiate (CAT), hydroxypropylmethyl cellulose phthalate (HPMCP), polyvinyl acetate phthalate (PVAP), cellulose acetate phthalate (CAP), shellac, copolymers of methacrylic acid and ethyl acrylate, copolymers of methacrylic acid and ethyl acrylate to which a monomer of methylacrylate has been added during polymerization, a mixture of amylose-butan-1-ol complex (glassy amylose) with Ethocel® aqueous dispersion, a coating formulation comprising an inner coating of glassy amylose and an outer coating of cellulose or acrylic polymer material, pectins (of various types), including calcium pectinate, carageenins, aligns, chondroitin sulfate, dextran hydrogels, guar gum, including modified guar gum such as borax modified guar gum, beta-cyclodextrin, saccharide containing polymers, e.g., a polymeric construct comprising a synthetic oligosaccharide-containing biopolymer including methacrylic polymers covalently coupled to oligosaccharides such as cellobiose, lactulose, raffinose and stachyose, or saccharide-containing, natural polymers including modified mucopolysaccharides such as cross-linked pectate; methacrylate-galactomannan, pH-sensitive hydrogels and resistant starches, e.g., glassy amylose. Other materials include methylmethacrylate or copolymers of methacrylic acid and methylmethacrylate having a pH dissolution profile that delays release in vivo of the majority of the ileal brake hormone releasing substance until the dosage form reaches the ileum may also be used. Such materials are available as Eudragit® polymers (Rohm Pharma, Darmstadt, Germany). For example, Eudragit® L100 and Eudragit® S100 can be used, either alone or in combination. Eudragit® L100 dissolves at pH 6 and upwards and comprises 48.3% methacrylic acid units per g dry substance; Eudragit® S100 dissolves at pH 7 and upwards and comprises 29.2% methacrylic acid units per g dry substance. Generally, the encapsulating polymer has a polymeric backbone and acid or other solubilizing functional groups. Polymers which have been found suitable for purposes of the present invention include polyacrylates, cyclic acrylate polymer, polyacrylic acids and polyacrylamides. A particularly preferred group of encapsulating polymers are the polyacrylic acids Eudragit® L and Eudragit® S which optionally may be combined with Eudragit® RL or RS. These modified acrylic acids are useful since they can be made soluble at a pH of 6 or 7.5, depending on the particular Eudragit chosen, and on the proportion of Eudragit® S to Eudragit® L, RS, and RL used in the formulation. By combining one of both of Eudragit® L and Eudragit® S with Eudragit® RL and RS (5-25%), it is possible to obtain a stronger capsule wall and still retain the capsule's pH-dependent solubility.
A delayed and/or controlled release oral dosage form used in the invention can comprise a core containing an ileum hormonal-stimulating amount of an ileal brake hormone releasing substance along with carriers, additives and excipients that is coated by an enteric coating. In some embodiments, the coating comprises Eudragit® L100 and shellac, or food glaze Eudragit® S100 in the range of 100 parts L100:0 parts S100 to 20 parts L100:80 parts S100, more preferably 70 parts L100:30 parts S100 to 80 parts L100:20 parts S100. In preferred alternatives, the preferred coating is a numeric coating which dissolves at the pH of the ileum (about 7-8, about 7.2-8.0, about 7.4-8.0, about 7.5-8.0) comprising a shellac, and emulsifiers such as triacetone and hypromellose, among others. Alternative nutrateric coatings include ethyl cellulose, ammonium hydroxide, medium chain triglycerides, oleic acid, and stearic acid. As the pH at which the coating begins to dissolve increases, the thickness necessary to achieve ileum-specific delivery decreases. For formulations where the ratio of Eudragit® L100:S100 is high, a coat thickness of the order 150-200 μm can be used. For coatings where the ratio Eudragit® L100:S100 is low, a coat thickness of the order 80-120 μm can be used in the present invention.
In still further embodiments, the present invention relates to a method of improving muscle functions and coordination in a patient in need thereof comprising administering an effective amount of a composition according to the present invention in a patient in need thereof, optionally in combination with a bioactive agent. Additional methods according to the present invention relate to improving the action of traditional anti-diabetes medications, including DPP-IV inhibitors, among others, that suppress GLP-1 inhibition/destruction and work to potentiate GLP-1 levels stimulated by compositions according to the present invention. The agents act in a synergistic manner to produce favorable results in diabetes (especially including type II) treatment:
In additional embodiments of the present invention, a method of treating impairment to or improving basal membrane structure of gastrointestinal tract comprises administering an effective amount of a compound according to the present invention to a patient in need thereof optionally in combination with a bioactive agent. This method may be used to treat, inhibit or reduce the likelihood of multiple sclerosis in a patient or to enhance recovery from injury which occurs secondary to radiation, chemotherapy or other toxins.

Obesity is a natural state in a setting of excessive availability of readily absorbed, dense and high nutritional content foods, typical of the modern western diet. Even alter obesity is fully developed it is reversible; Both RYGB and oral ileal stimulation of ileal hormones with Brake will restore some physiological signaling.
The present invention approaches the problem of insulin resistance in a natural physiological manner by stimulating hormones in the lower gut, that is, the ileum, which act synergistically to reduce insulin resistance, so as to promote a substantial equilibrium between the amount of insulin produced and the amount of blood glucose, it does this using natural ileal brake hormone releasing components in healthful, pleasant compositions which am preferably coated using a polymeric, preferably nutrateric coating to release effective ileal brake hormone releasing substances within the ileum of a patient or subject and effect a natural physiological response within the subject's ileum with favorable results. The present invention represents a change in the nature of treating an insulin imbalance in a subject, using a more wholesome, natural physiological process, completely distinguishable over pharmaceutical or synthetic approaches. Use of this formulation to release L-cell derived regulatory substances into the portal blood supply to the liver avoids the disadvantages of peripherally administered analogues of similar L-cell derived regulatory substances. The present invention may also be used treat noninsulin dependent diabetes mellitus, pre-diabetes syndrome, metabolic syndrome, glucose intolerance and insulin resistance as well as a number of gastrointestinal tract disorders or conditions as otherwise described herein. The following definitions are used to describe the present invention and apply unless otherwise indicated.
The term “patient” or “subject” is used throughout the specification within context to describe an animal, generally a mammal and preferably a human, to whom treatment, including prophylactic treatment, with the compositions and/or methods according to the present invention, is provided. For treatment of a particular condition or disease state which is specific for a specific animal such as a human patient, the term patient refers to that specific animal.
The term “effective” is used herein, unless otherwise indicated, to describe an amount of a compound, composition or component and for an appropriate period of time which, in context, is used to produce or effect an intended result, whether that result relates to the treatment of a disorder or condition associated with the present invention or alternatively, is used to produce another compound, agent or composition. This term subsumes all other effective amount or effective concentration terms which are otherwise described in the present application. In many instances, with the administration of D-glucose (dextrose) as a ileal brake hormone releasing substance in compositions and methods according to the present invention, an effective amount of D-glucose ranges from about 500 mg, to about 12.5 grams or more, preferably about 10 grams used on a daily basis.
The term “nutritional substance” is used synonymously with “pharmaceutical composition” and “ileal brake hormone releasing substance” in certain contexts herein and refers to the substance which produces the intended effect in the ileum of a patient or subject pursuant to the present invention. A “nutritional substance” includes, but is not limited to, proteins and associated amino acids, fats including saturated fats, monosaturated fats, polyunsaturated fats, essential fatty acids, Omega-3 and Omega-6 fatty acids, trans fatty acids, cholesterol, fat substitutes, carbohydrates such as dietary fiber (both soluble and insoluble fiber), starch, sugars (including monosaccharides, fructose, galactose, glucose, disaccharides, lactose, maltose, sucrose, and alcohol), polymeric glucoses including inulin and polydextrose, natural sugar substitutes (including brazzein, Curculin, erythritol, fructose, glycyrrhizin, glycyrrhizin, glycerol, hydrogenated starch hydrosylates, isomalt, lactitol, mabinlin, maltitol, mannitol, miraculin, monellin, pentadin, sorbitol, stevia, tagatose, thaumatin, and xylitol), sahlep, and halwa root extract. D-glucose (dextrose) is a preferred ileal brake hormone releasing substance. Ileal brake hormone releasing substances include all compositions that yield the aforementioned nutrients upon digestion or that contain such nutrients, including polymeric forms of these nutrients.
Additional ileal brake hormone releasing components which may be included in compositions according to the present invention include, barley grass, known to be a rich source of highly metabolizable vitamins and minerals such as vitamins A, B1, B2, B6, B12 and C, potassium, magnesium, and zinc. In addition, barley grass also has a high concentration of the enzyme superoxide dismutase (SOD), which has been shown to have high levels of antioxidant activity. Barley grass is believed to be an important nutrient in the regulation of the digestive process because the micronutrients, enzymes (e.g., SOD), and fiber contained in barley grass are believed to improve intestinal function.
Alfalfa fresh or dried leaf tea is also usable in the invention, to promote appetite, and as a good source of chlorophyll and fiber. Alfalfa contains biotin, calcium, choline, inositol, iron, magnesium, PABA, phosphorus, potassium, protein, sodium, sulfur, tryptophan (amino acid), and vitamins A, B complex, C, D, B, K, P, and U. Alfalfa supplements are recommended for treating poor digestion, and were shown to lower cholesterol levels in animal studies. Alfalfa is categorized as Generally Regarded as Safe (GRAS) by the FDA. Dosages can range from 25-1500 mg, preferably 500-1000 mg dried leaf per day.
Chlorella is yet another substance usable in the invention in combination with the ileal brake hormone releasing substance (preferably D-glucose or dextrose), being a genus of unicellular green algae, grown and harvested in tanks, purified, processed and dried to form a powder. Chlorella is rich in chlorophyll, carotenes, and contains the full vitamin B complex, vitamins E and C, and has a wide range of minerals, including magnesium, potassium, iron and calcium. Chlorella also provides dietary fiber, nucleic acids, amino acids, enzymes, CGF (Chlorella Growth Factor) and other substances. Dosages can range from 300-1500 mg/day.
Chlorophyllin is yet another ileal brake hormone releasing substance, being a known food additive and has been used as an alternative medicine. Chlorophyllin is a water-soluble, semi-synthetic sodium/copper derivative of chlorophyll, and the active ingredient in a number of internally-taken preparations intended to reduce odors associated with incontinence, colostomies and similar procedures, as well as body odor in general. It is also available as a topical preparation, purportedly useful for treatment and odor control of wounds, injuries, and other skin conditions, such as for radiation burns.
Sodium alginate may also be used as a nutritional substance, preferably in combination with D-glucose or dextrose.
The term “ileum” is used to describe the third (of three) portion of the small intestine just before the small intestine becomes the large intestine in the gastrointestinal tract. The ileum is the final section of the small intestine in higher vertebrates, including mammals. The ileum follows the duodenum and jejunum in the small intestine, and is separated from the “Cecum” by the ileocecal valve (ICV), in humans, the ileum is about 2-4 meters long, and the pH usually ranges between 7 and 8 (neutral or slightly alkaline). The function of the ileum is mainly to absorb vitamin B12 bile salts and whatever products of digestion were not absorbed by the jejunum. The wall itself is made up of folds, each of which has many tiny finger-like projections known as “villi” on its surface. In turn, the epithelial cells which line these villi possess even larger numbers of microvilli. Therefore, the ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion. The DNES (diffuse neuroendocrine system) cells that line the ileum contain lesser amounts of the protease and carbohydrase enzymes (gastrin, secretin, and cholecystokinin) responsible for the final stages of protein and carbohydrate digestion. These enzymes are present in the cytoplasm of the epithelial cells.
The term “delays the release in vivo of the majority of the ileal brake hormone releasing substance until the dosage form reaches the subject's ileum” means: (1) that not less than around 50% by weight, not less than around 70% by weight, more preferably not less than around 80% by weight, and more preferably not less than around 90% and in certain instances substantially all of the ileal brake hormone releasing substance remains unreleased in vivo prior to the dosage form's arrival al a subject's ileum; and (2) that not less than around 50%, not less than around 70% by weight, more preferably not less than around 80% by weight, and more preferably not less than around 90%, of the ileal brake hormone releasing substance is remains released in vivo by the time when the dosage form enters the subject's ileum. In preferred aspects of the invention this amount is at least about 1 gram, at least about 2.5 grams, at least about 3 grams, at least about 5 grams, at least about 7.5 grams, preferably about 10 grams to about 12-12.5 grams or more (about 12.5 to about 20 grams, especially of polymeric materials such as polydextrose or those compounds of higher molecular weight) of the ileal brake hormone releasing substance and in particular, glucose, is released within the small intestine in the ileum in order to stimulate ileum hormones and related hormones and effect the intended result associated with lowering the manifestations of metabolic syndrome and/or influencing one or more of insulin resistance (decrease resistance), blood glucose (decrease m/stabilize glucose levels), glucagon secretion (decrease), insulin release (decrease and/or stabilize release and/or levels), ileum hormone release (increase) or other hormone release, in particular, one or more of GLP-1, glicentin, C-terminally glycine-extended GLP-1 (7 37), (PG (78 108)); C-peptide, intervening peptide-2 (PG (111 122) amide); GLP-2 (PG (126 158), GRPP (PG (1 30)), oxyntomodutin (PG (33 69), and other peptide fractions to be isolated, PYY (1-36), PYY (3-36), cholecystokinin (CCK), gastrin, enteroglucagon, secretin, as well as leptin, IGF-1 and IGF-2, and preferably, one or more, two or more, three or more, four or more, five or more, six or more, seven or more, or all of GLP1, GLP2, C-peptide, PYY (1-36 and/or 3-36), glucagon, leptin, IGF-1 and IGF-2.
The term “ileum hormones” includes all hormones that are associated with intraluminal food substances stimulating the release of said hormones, could lie associated with action of the ileal brake and associated feedback, from the ileum or ileum-related stimulation of insulin secretion or inhibition of glucagon secretion. “Ileum hormones” therefore include, but are not limited to, GLP-1, glicentin, C-terminally glycine-extended GLP-1 (7 37), (PG (78 108)); intervening peptide-2 (PG (111 122)amide); GLP-2 (PG (126 158), GRPP (PG (1 30)), oxyntomodulin (PG (33 69), and other peptide tractions to be isolated, PYY (PYY 1-36) and (PYY 3-36), cholecystokinin (CCK), gastrin, enteroglucagon and secretin.
The term “ileum hormone-stimulating amount of a nutritional substance” means any amount of a nutritional substance that is effective to induce measurable hormone release in the ileum, and induce feedback from the ileum or ileum-related stimulation of insulin secretion or inhibition of glucagon secretion, or other effect such as shutting down or decreasing insulin resistance and increasing glucose tolerance. Consequently, an “ileum hormone-stimulating amount of a nutritional substance” can vary widely in dosage depending upon factors such as the specific nutrient at issue, the desired effect of administration, the desired goal of minimizing caloric intake, and the characteristics of the subject to whom the ileal brake hormone releasing substance is administered. For example, at least about 500 mg of D-glucose is used, and a particularly preferred ileum hormonal-stimulating amount of D-glucose includes between about 7.5-8 g to about 12-12.5 g (preferably around 10 g).
The term “gastrointestinal disorder” includes diarrheal states, malabsorption in the upper gut (i.e., chronic pancreatitis, celiac disease), fatty liver, atrophic gastritis, short bowel syndrome, radiation enteritis, irritable bowel disease, Crohn's disease, post infectious syndrome, mild reflux, certain gut dysmotility, post chemotherapy disorder, malnutrition, malabsorption, and voluntary or involuntary long term starvation. Ille present invention may be used to treat each of these conditions, alone or secondary to the treatment or resolution of symptoms associated with noninsulin dependent diabetes mellitus, pre-diabetic symptoms, metabolic syndrome and insulin resistance.
Dosage forms used in methods of the invention can be in a form suitable for oral use, for example, as tablets, troches, lozenges, suspensions, micro suspensions, dispersible powders or granules, emulsions, micro emulsions, hard or soft capsules. Useful dosage forms include osmotic delivery systems as described in U.S. Pat. Nos. 4,256,108; 5,650,170 and 5,681,584, multiparticulate systems as disclosed in U.S. Pat. No. 4,193,985; systems in which the nutritional substance is coated with a mixed film of a hydrophobic organic compound-enteric polymer as disclosed in U.S. Pat. No. 6,638,534; systems such as diose described in U.S. Pat. Nos. 7,081,239; 5,900,252; 5,603,953; and 5,573,779; enteric-coated dry emulsion formulations (e.g., Journal of Controlled Release, vol. 107, issue 1 20 Sep. 2005, Pages 91-96), and emulsions such as the emulsion system of Olibra® and those disclosed in U.S. Pat. No. 5,885,590. Those of ordinary skill in the prior art know how to formulate these various dosage forms such that they release the majority of their nutritional substance in a subject's ileum as otherwise described herein.
Exemplary dosage forms that will release the majority of the ileal brake hormone releasing substance in vivo upon reaching the ileum include oral dosage forms such as tablets, troches, lozenges, dispersible powders or granules, or a hard or soft capsules which are formed by coating the ileal brake hormone releasing substance with an enteric coating (e.g., an enteric cellulose derivative, an enteric acrylic copolymer, an enteric maleic copolymer, an enteric polyvinyl derivative, or shellac). Preferred enteric coatings have a pH dissolution profile that delays the release in vivo of the majority of the ileal brake hormone releasing substance until the dosage form reaches the ileum. Enteric coatings can consist of a single composition; or can comprise two or more compositions, e.g., two or more polymers or hydrophobic organic compound-enteric polymer compositions as described in U.S. Pat. No. 6,638,534).
A “material having a pH dissolution profile that delays release in vivo of the majority of the ileal brake hormone releasing substance until the dosage form reaches the ileum” includes but is not limited to cellulose acetate trimellitate (CAT), hydroxypropylmethyl cellulose phthalate (HPMCP), polyvinyl acetate phthalate (PVAP), cellulose acetate phthalate (CAP), shellac, copolymers of methacrylic acid and ethyl acrylate, copolymers of methacrylic acid and ethyl acrylate to which a monomer of methylacrylate has been added during polymerization, a mixture of amylose-butan-1-ol complex (glassy amylose) with Ethocel® aqueous dispersion (Milojevic et al., Proc. Int. Symp. Contr. Rel Bioact. Mater. 20, 288, 1993), a coating formulation comprising an inner coating of glassy amylose and an outer coating of cellulose or acrylic polymer material (Allwood et al. GB 9025373.3), calcium pectinate (Rubenstein et al., Pharm. Res., 10, 258, 1993) pectin, chondroitin sulfate (Rubenstein et al. Pharm. Res. 9, 276, 1992), resistant starches (PCT WO 89/11269), dextran hydrogels (Hovgaard, et al., 3rd Eur. Symp. Control. Drug Del., Abstract Book, 1994, 87) modified guar gum such as borax modified guar gum, (Rubenstein and Gliko-Kabir, S. T. P. Pharma Sciences 5, 41-46, 1995), beta-cyclodextrin (Sidke et al., Eu. J. Pharm. Biopharm. 40 (suppl), 335, 1994), saccharide containing polymers, e.g., a polymeric construct comprising a synthetic oligosaccharide-containing biopolymer including methacrylic polymers covalently coupled to oligosaccharides such as cellobiose, lactulose, raffinose and stachyose, or saccharide-containing, natural polymers including modified mucopolysaccharides such as cross-linked pectate (Sintov and Rubenstein PCT/US 91/03014); methacrylate-galactomannan (Lehmann and Dreher, Proc. Int. Symp. Control. Rel. Bioact. Mater. 18, 331, 1991) and pH-sensitive hydrogels (Kopecek et al., J. Control Rel 19, 121, 1992), and resistant starches, e.g., glassy amylose.
Methylmethacrylate or copolymers of methacrylic acid and methylmethacrylate are preferred materials having a pH dissolution profile that delays release in vivo of the majority of the ileal brake hormone releasing substance until the dosage form reaches the ileum. Such materials are available as Eudragit® polymers (Rohm Pharma, Darmstadt, Germany). For example, Eudragit® L100 and Eudragit® S100 can be used, either alone or in combination, Eudragit® L100 dissolves at pH 6 and upwards and comprises 48.3% methacrylic acid units per g dry substance; Eudragit® S100 dissolves at pH 7 and upwards and comprises 29.2% methacrylic acid units per g dry substance. Generally, the encapsulating polymer has a polymeric backbone and acid or other solubilizing functional groups. Polymers which have been found suitable for purposes of the present invention include polyacrylates, cyclic acrylate polymer, polyacrylic acids and polyacrylamides. Another preferred group of encapsulating polymers are the polyacrylic acids Eudragit® L and Eudragit® S which optionally may be combined with Eudragit® RL or RS. These modified acrylic acids are useful since they can be made soluble at a pH of 6 or 7.5, depending on the particular Eudragit chosen, and on the proportion of Eudragit® S to Eudragit® L, RS, and RL used in the formulation. By combining one or both of Eudragit® L and Eudragit® S with Eudragit® RL and RS (5-25%), it is possible to obtain a stronger capsule wall and still retain the capsule's pH-dependent solubility. In additional preferred aspects of the invention, a coating of shellac (which also includes one or more emulsifiers such as hypromellose and/or triacetin) which is chosen to have a suitable pH-dependent dissolution profile for release die contents of a dosage form such as a tablet within the ileum of a patient or subject may be used. This type of coating provides a nutrateric approach to delayed and/or controlled release using naturally occurring, non-synthetic components.
A delayed and/or controlled release oral dosage form used in the invention can comprise a core containing an ileum hormonal-stimulating amount of a ileal brake hormone releasing substance that is coated by an enteric coating. In some embodiments, the coating comprises Eudragit® L100 and shellac, dr food glaze Eudragit® S100 in the range of 100 parts L100:0 parts S100 to 20 parts L100:80 parts S100, more preferably 70 parts L100:30 parts S100 to 80 parts L100:20 parts S100. As the pH at which the coating begins to dissolve increases, the thickness necessary to achieve ileum-specific deli very decreases. For formulations where the ratio of Eudragit® L100:S100 is high, a coat thickness of the order 150-200 μm can be used. For coatings where the ratio Eudragit® L100:S100 is low, a coat thickness of the order 80-120 μm can be used. Dosage forms used in methods of the invention can include one or more pharmaceutically acceptable carriers, additives, or excipients. The term “pharmaceutically acceptable” refers to a carrier, additive or excipient which is not unacceptably toxic to the subject to which it is administered. Pharmaceutically acceptable excipients are described at length by E. W. Martin, in “Remington's Pharmaceutical Sciences”, among others well-known in the art, pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose, and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7); wetting agents, such as, for example, cetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; and (10) coloring agents.

The terms “obesity” and “overweight” are generally defined by body mass index (BMI), which is correlated with total body fat and estimates the relative risk of disease. BMI is calculated by weight in kilograms divided by height in meters squared (kg/m2). Normal BMI is defined as a BMI of about 183 to 24.9 kg/m2. Overweight is typically defined as a BMI of 25-29.9 kg/m2, and obesity is typically defined as a BMI of at least 30 kg/m2. See, e.g., National Heart, Lung, and Blood institute, Clinical Guidelines on the Identification, Evaluation, and Treatment of Overweight and Obesity in Adults. The Evidence Report, Washington, D.C.: U.S. Department of Health and Human Services, NIH publication no. 98-4083 (1998). Obesity and its associated disorders are common and very serious public health problems in the United States and throughout the world. Upper body obesity is the strongest risk factor known for type 2 diabetes mellitus and is a strong risk factor for cardiovascular disease. Obesity is a recognized risk factor for hypertension, atherosclerosis, congestive heart failure, stroke, gallbladder disease, osteoarthritis, sleep apnea, reproductive disorders such as polycystic ovarian syndrome, cancers of the breast, prostate, and colon, and increased incidence of complications of general anesthesia. Obesity reduces life-span and carries a serious risk of the co-morbidities listed above, as well as disorders such as infections, varicose veins, acanthosis nigricans, eczema, exercise intolerance, insulin resistance, hypertension hypercholesterolemia, cholelithiasis, orthopedic injury, and thromboembolic disease (Rissanen et al., Br. Med. J. 301: 835-7 (1990)). Obesity is also a risk factor for the group of conditions called insulin resistance syndrome, or “Syndrome X” and metabolic syndrome. The present compositions are useful for treating obesity, and favorably impact the conditions which often occur secondary to obesity.
“Obesity-related disorder” includes all of the diseases and disorders mentioned in the preceding definition of “obesity”.
“Once-daily administration to the subject of a delayed and/or controlled release dosage form” includes self-administration of the dosage form by the subject.
“Dietary components” in the phrase “wherein the nutritional substance comprises a micro-encapsulation of glucose, lipids and dietary components” means any natural substance which either itself evidences impact on the ileal brake, or alternatively, enhances the impact that glucose and/or lipids have on the ileal brake, such components including other complex carbohydrates and nutritional components as otherwise described herein including, for example, alfalfa leaf, chloretlla algae, chlorophyllin and barley juice concentrate, among a number of other agents.
As summarized above, the invention provides methods for, the treatment of metabolic syndromes including hyperlipidemia, weight gain, obesity, insulin resistance, hypertension, atherosclerosis, fatty liver diseases and certain chronic inflammatory states. These methods can entail the testing of biomarkers; testing of breath, blood or body fluid biomarkers and selection of pharmaceutical compositions to resolve one or more of the metabolic syndrome conditions including but not limited to hyperlipidemia, weight gain, obesity, insulin resistance, hypertension, and atherosclerosis, fatty liver and chronic inflammatory states.
Thus, the invention provides a method of treatment of metabolic syndromes, wherein personalized treatments and pharmaceutical compositions are selected using the results of biomarker testing such as HbA1c, glucose, GLP-1, PYY, GLP-2, Proinsulin, CRP, hsCRP, endotoxin, IL-6. Personalized treatment and pharmaceutical compositions can be selected using a Glucose Supply Side computerized algorithm and system, wherein said Glucose Supply Side treatment method for diabetes consists of an algorithm (incorporated herein in its entirety) ranking favorable attributes of pharmaceutical compositions acting by minimizing excess glucose inside cells, and minimizing the amount of glucose that reaches target cells of the metabolic syndrome afflicted patient.
The invention also provides a method of treatment of metabolic syndromes, wherein personalized treatment and pharmaceutical compositions are selected by comparison of biomarker behavior patterns between patients having responded to Roux-en-Y bariatric surgery and their own response to oral dosing with pharmaceutical formulations comprised of carbohydrates, lipids or amino acids which activate the ileal brake response of the ileum in a manner similar to Roux-en-Y surgery. The method specifically entails orally administered pharmaceutical compositions that mimic, the action of Roux-en-Y gastric bypass surgery on the ileal brake. Even more specifically, the formulation for treatment of metabolic syndrome comprises the micro-encapsulation of glucose, lipids and components of diet formulated to release these active compositions at pH values between 6.5 and 7.5, which targets the action of said medicaments at the ileal brake in the distal intestine. The encapsulated compositions disclosed are a preferred medicament to decrease appetite for glucose, and thereby lower inflammation and benefit to the treatment of patients with metabolic syndrome, according to the results of testing of targeted biomarkers.
In a preferred embodiment of a method of treatment of metabolic syndromes according to the invention, oral dosing with about 2,000 to 10,000, about 2500-3,000 to, 10.000, about 7,500-10,000 milligrams of a pharmaceutical formulation of microencapsulated sugars, lipids, and/or amino acids activates the ileal brake in a dose increasing magnitude and treats one or more of the following components of metabolic syndrome: hyperlipidemia, weight gain, obesity, insulin resistance, hypertension, atherosclerosis, fairy liver diseases and chronic inflammatory states. The name of this medicament is BRAKE™.
In another embodiment, the invention provides a pharmaceutical formulation for treatment of metabolic syndrome, wherein the microencapsulated activation of the ileal brake is produced at a pH of about 6.5 to about 7.5 and involves the release of about 2,000 to about 10.000, about 2,500-3,000 to 10,000, about 7,500 to 10,000 milligrams of glucose, fructose, dextrose, sucrose or other glucose compositions active on the ileal brake in mammals at dosages between about 2,000 and about 10,000 milligrams, and as presented above.
In another embodiment, the invention provides a pharmaceutical formulation wherein the microencapsulated activation of the ileal brake is produced by approximately pH 6.5 to 7.5 release of about 2,000 to about 6,000, about 2,500-3,000 to about 10,000 milligrams of dextrose and about 2,000-4,000 milligrams of a lipid such as olive oil, corn oil, palm oil, omega3 fatty acid or other suitable lipid substances active on rite ileal brake of mammals.
In one embodiment, a pharmaceutical formulation for treatment of metabolic syndrome of the invention can achieve the microencapsulated activation of the ileal brake at about pH 6.5 to 7.5 by release of about 2,000 to about 10,000, about 2,500-3,000 to about 10,000, about 7,500-10,000 milligrams given once, twice or three times daily.
In another embodiment, a method of treatment of metabolic syndrome according to the invention involves oral treatment and includes use of pharmaceutical formulations as described above that activate the ileal brake and which act in the gastrointestinal, tract and the liver of a mammal to control metabolic syndrome manifestations and thereby reverse or ameliorate the cardiovascular damage (atherosclerosis, hyper tension, lipid accumulation, and the like) resulting from progression of metabolic syndrome.
In another preferred embodiment, a composition or a method of treatment of metabolic syndromes according to the invention involves an oral formulation mimetic of RYGB and includes use of said oral formulation with medicaments ordinarily used for treatments of manifestations of metabolic syndrome including but not necessarily limited to diabetes, hyperlipidemia, atherosclerosis, hypertension, obesity, insulin resistance, or chronic inflammation. The added combination pharmaceutical agent can be, by way of specific example, metformin, sitagliptin, saxagliptin, methotrexate, olanzapine, donepezil, memantine, atorvastatin, simvastatin, lovastatin, olmesartan, Enalapril, lisinopril, candesartan, irbesartan. Such compositions are the first to combine treatment of all of the primary metabolic syndrome manifestations into one product given once or twice daily to patients with all or many of the manifestations of metabolic syndrome.
In a preferred example, a composition of the invention can act to limit hepatic gluconeogenesis in the same manner as metformin, as well as add many other actions beneficial to the treatment of metabolic syndrome. The class of compounds related to and including metformin is called biguanide antihyperglycemic agents. While metformin is illustrative, and the combination product therefrom is called MetaBrake, the list of biguanides is not exclusive beyond metformin, and additional metformin mimetic or biguanide medicaments can be added to the formulations of the invention without departing from the practice of treatments for metabolic syndrome that combine oral mimetics of Roux-en-Y surgery effects on the ileal brake in conjunction with conventional anti-diabetes medicaments of the class represented by metformin. When used together with biguanide medicaments with particular metformin, the dosage required to lower glucose, lipids, obesity and inflammation may be reduced. When combined into an oral dosage form of Brake and a biguanide such as metformin, each tablet would contain about 500 mg of ileal hormone releasing substances and 25-50 mg of metformin, hi this manner the total dose of metformin per day would-be about 75 mg to about 150 mg and the ileal hormone releasing substance would be less than about 1500 mg, yet the combined product would control glucose, lower body weight, control triglycerides and lower systemic inflammation, actions that are somewhat beyond diose of metformin alone.

While illustrative, this list is not meant to be exhaustive and it is readily apparent to persons skilled in the art of diabetes care that additional DPP-IV inhibitors can be added to the formulations of the invention without departing from the practice of preparing oral treatments for metabolic syndrome that combine oral mimetics of RYGB surgery effects on the ileal brake in conjunction with conventional anti-diabetes medicaments of the class represented by DPP-IV inhibitors. When used together with so called DPP-IV inhibitors, the dosage required to lower glucose, lipids, obesity and inflammation may be reduced to the benefit of reduction of the side effects of DPP-IV inhibitors, in particular the pancreatitis, which is presumed to be related to dosage of DPP-IV inhibitor chosen for treatment. When combined into an oral dosage form of Brake and a DPP-IV inhibitor such as sitagliptin, by way of example, each tablet would contain about 500 mg of ileal hormone releasing substances and 5 mg of sitagliptin. In this manner the total dose of sitagliptin per day would be less than 100 mg, yet the combined product would, in a completely novel way, control glucose, lower body weight, control triglycerides and lower systemic inflammation in a similar manner as RYGB surgery. This combination product of Brake and sitagliptin, called JanuBrake would be given once or twice daily and be suitable for consumer use of sitagliptin with an increased safety profile over that of sitagliptin alone. Similar gains in potency at lower doses, broad array of treatment responses in metabolic syndrome, and safety advantages over the statin alone would be seen with each of the DPP-IV inhibitors reduced to practice, and the disclosure of invention of a synergistic combination encompasses all DPP-IV inhibitor combinations with Brake prepared in this manner for these purposes.

When used together with so called statins, the dosage required to lower lipids and triglycerides may be reduced to the benefit of reduction of the side effects of statins, in particular the myopathy, which is known in the art to be related to higher dosages such as 80 mg of simvastatin. When combined into an oral dosage form of Brake and a statin such as atorvastatin, by way of example, each tablet would contain 500 mg of ileal hormone releasing substances and 1-2 mg of atorvastatin. In this manner the total dose of atorvastatin per day would be less than 20 mg, yet the combined product would control glycose, lower body weight, control triglycerides and lower systemic inflammation. This product, called LipidoBrake would be given once or twice daily and be suitable for consumer use of atorvastatin with an improved safety profile over that of atorvastatin alone. Similar gains in potency at lower doses, a broad array of treatment responses in metabolic syndrome, and safety advantages over the statin alone would be seen with each of the statins reduced to practice, and the disclosure encompasses all statin combinations with Brake prepared in this manner for these purposes.

The invention is described further in the following examples of the following Experimental-Section, which are illustrative and are not limiting.
In the Examples described hereinafter, the same table-numbers may be used, in different examples. For example, Examples 1-4 contain a “Table 1”, and Example 5 contains a different. (able which is also designated as “Table 1”. When an example refers to a table number, it means the table contained within that example.
600 mg/capsule glucose
1000 mg capsule
10% Eudragit coating
Plasticizer (propylene glycol, triethyl acetate and water)
Magnesium stearate
Silicon Dioxide
A single formulation as described for formulation 1 above was-administered to five healthy adult human volunteers fasting in the morning at bedtime. Each of the volunteers was in the fasted state (i.e., none had eaten within two hours of the formulation administration). Blood levels (ng/ml) of GLP-1, GLP-2, C-peptide, GLP-1 (total) (determined by radioimmunoassay (RIA)), PYY, blood glucose (BS), GLP-1 (total) (with plasma), and insulin for each of the volunteers were measured just prior to administration of the above formulation and every four hours after administration until the eleventh hour after administration of the formulation.
Based on the data obtained for the live individuals tested as above, it was concluded that for all subjects except for one, that blood levels of GLP-1 (total) (RIA), GLP-1 (total) (with plasma), GLP-2, PYY, insulin, C-peptide, and blood glucose peaked at around 6-10 hours after administration of formulation 1. The peak levels of GLP-1 (total) (RIA), GLP-1 (total) (with plasma), GLP-2, and PYY correlated with the peak levels of insulin, C-peptide, and blood glucose, especially for subjects D and B. This suggests that there is an inverse correlation between these two groups and therefore the stimulation of the first grouping causing a reduction of levels of the second grouping.
Further, blood glucose and insulin levels dropped as the result of the stimulation of GLP-1, GLP-2, C-peptide, PYY, and insulin.
After the experiment described in this example, some patients continued to take formulation 1 above for an extended period of time and experienced a beneficial weight loss and as well as in one patient significant control of blood glucose and insulin levels.
Levels of blood glucose, ileal brake derived hormones and their response to food stimulation could be assessed and abnormalities in the ileal brake responsiveness could be evaluated (GLP-1, GLP-2, PYY). This indicates that methods of the invention can be used to diagnose whether a subject suffers from a disorder associated with an abnormality in their ileal brake hormones to respond to food, blood glucose or insulin levels. For example, a standard dosage form comprising an enterically-coated, ileum hormone-stimulating amount of a ileal brake hormone releasing substance could be administered to a subject, the subject's levels of ileal hormones blood glucose and insulin as well as ileal hormones including GLP-1, GLP-2, PYY, IGF-1, IGF-2 and leptin could be measured at regular intervals subsequent to administration of the ileal brake hormone releasing substance. Measured levels of the ileal hormones (e.g., GLP-1, GLP-2, PYY, IGF-1, IGF-2), as welt as blood glucose and insulin could be compared to healthy levels of ileal brake hormones, blood glucose and insulin determined by administering an equivalent enterically-coated, ileum hormone-stimulating amount of a ileal brake hormone releasing substance to a control subject.
Further, this example and the following examples establish that compositions such as formulation 1 above, among others, when administered while the subject is in the fasted state and at a time of about 3 to 12 hours, preferably about six to about nine horn's prior to the subject's next intended meal, provide an ileum hormone-stimulating amount of a ileal brake hormone releasing substance.
Formulation II
Chlorella Algae
Formulation II was provided by mixing the actives with corn starch, stearic acid, magnesium stearate and silicon dioxide and pressing into a tablet, and coating the tablet, with shellac (either 10% or 8% shellac), triacetin and the hypromellose. A Eudragit coating could alternatively be used, similar to that which coats formulation 1, as described above.
Based upon the results in examples 1 and 2, the inventors embarked upon a project to create a vehicle which can be given orally and deliver the ileal brake hormone releasing substance to the ileum to stimulate the ileal brake. The following data (appearing in attached
The experiment was performed on volunteers as part of the testing of the different compositions, and structure of the pill in order to determine the best stimulation. The present example reports the results of the live patients that took formulation II as well as the graphs associated with it (
Applicants note that the other pill compositions tested showed similar but less significant stimulation and a slight modification in pattern, in accordance with the expected formulation release and stimulation of the pills. The subjects were monitored at all times by a registered nurses and a physician. The results appear in
Regarding the response of glucose, c-peptide and insulin to the composition of the present invention, that dam is summarized in
In this set of experiments, the inventor was able to stimulate hormones of the ileal break using a safe, effective oral formulation comprising ileal brake hormone releasing substances with enteric release (delayed/controlled release) helps to curb appetite in a natural way without the side effects of prior art methods. The experiments evidenced a coherent pattern of hormone release that can serve as a diagnostic tool for testing the ileal break hormones for insufficiencies, excesses or other abnormalities. Also shown is the fact that the present invention stimulates IGF1 and IGF2 and leptin as well as decreasing/suppressing insulin resistance and enhancing glucose tolerance, giving it excellent prospects for treating NIDDM (type II diabetes mellitus), prediabetes, metabolic syndrome and insulin resistance. By stimulating the ileal hormones pursuant to the present invention, the present invention represents an enhancer of well-being, muscle mass preservation or production. Further, the present invention also is able to stimulate glucagon, glucagon-like (enteroglucagon, etc.).
An experiment was undertaken using two different formulas (including formula H, above, in order to determine the maximum yield of the pills given to subjects. The subjects were divided in groups of 7, and different pills compositions were given to each.
The object was to investigate and measure multiple parameters besides blood glucose, such as glucose homeostasis to include insulin, eupeptide, glucose, IGF-1, IGF-2, glucagon, as well as leptin. The composition of the pills was developed in such a way so as to decrease the number of pills from an initial 16 to 7. The pills were given orally while fasting, and the blood work was drawn hourly for all parameters and each tube was coded for, both time, and patient. The blood product was handled by a professional staff prepared as required by the different tests, and the samples sent to two different national labs drat provided results in coded numbers.
Once decoded and analysed for each patient, the results were taken as the average response to the different parameters for the different patients, considering that some of these subjects presented with either an abnormal insulin level, abnormal glucose level or both.
The two pills composition used during this testing were as follows (ingredients per tablet, in mg), Formula II (as above) in Example 3:
Chlorella Algae
Formulation II was provided by mixing the actives with corn starch, stearic acid, magnesium stearate and silicon dioxide into a tablet, and coating the tablet with the shellac, triacetin and the hypromellose. The shellac was either a European shellac (Aphoeline-1) or an Indian shellac (Aphoeline 2), as described above.
Formula III used a coating composed of 2% clear polyvinyl alcohol (PVA) coating plus 14% of a nutrateric coating (Aphoeline-O). The clear coating was made up of polyvinyl alcohol, talc, polyethylene glycol, polysorbate 80; the nutrateric coating was made up of ethyl cellulose, ammonium hydroxide, medium chain triglycerides, oleic acid, and stearic acid. The proprietary blend of active ingredients comprised sodium alginate and dextrose, 1150 gm (85% by weight of Formula III).
Protocol Testing.
All subjects were volunteers that signed an informed consent in regard to the GRAS compliant supplement which was to be administered. Each subject presented fasting, with the last oral intake having occurred the night prior. Baseline lab work was completed, including blood glucose, insulin and, c-peptide, as well as other hormones. Samples were collected by licensed professionals, and handled by professional lab technicians. The sample tubes were labeled according to a preset protocol, for anonymity and shipped in frozen containers as specified by the contracted, licensed labs for testing.
Sampling was done on an hourly basis, before and after the oral ingestion of the supplement. Vitals were taken before each draw. No food or drink was allowed prior or during the test, though water was allowed adlib. The results were compiled in the enclosed Tables, illustrated by the enclosed charts comprising
The subjects selected were part of a much larger group, with only those that were found to have abnormal insulin or abnormal blood glucose or both included. There were no significant changes in levels of insulin, glucose or c-peptide for the rest of the group.
As evidenced by the figures and the corresponding tables, generally, blood glucose as well as insulin decreased and/or stabilized, in response to administering the ileal brake hormone releasing substance, which apparently results in a hormonal stimulation. This response appears to be greater the higher the starting value, indicating a significant decrease in insulin resistance. Also it can be noted that the more normal the value of insulin and glucose, the less significant are the changes to their values, indicating that the effect of the pill is self-limiting, that is, surprisingly, the ileal brake hormone releasing substance acts favourably to correct abnormal level shut does not pose a danger of decreasing blood glucose below normal, so there is no risk for hyperglycaemia. This makes the ileal brake hormone releasing substance particularly useful in persons who are only exhibit pre-diabetic symptoms, where drug therapy has not yet been indicated or is not preferred given the risk of side effects.
Established safe and effective dose ranges in humans for the ileal brake hormone releasing substance of the invention ranges from 500 to 12500 mg/day, preferably within the range of about 7,500 mg/day to about 12,000 mg/day, preferably about 10,000 mg/day. While not being limited by way of theory, the product therefore negates/reduces insulin resistance, thereby allowing blood glucose to enter the cells, with insulin at normal levels, as opposed to the abnormally high levels of insulin generated in the test subjects, and therefore decreasing insulin levels to baseline. This allows the body to use mote energy while decreasing the noxious effect of high insulin that promote obesity as well as the vicious cycle associated with high insulin levels, such as per metabolic syndrome, polycystic ovaries, arteriosclerosis, hypertension, fatty liver, etc.
The insulin production modulation achieved by administering the inventive formulating containing GRAS ingredients is believed to occur through the action of a stimulated hormone within the lower gut, which either acts through IGF like receptors or through a different receptor than foe receptor for IGF or insulin, possibly like receptor IRR. Since the ileal brake hormone releasing substance composition is not absorbed and appears to work through hormone stimulation, a new hormone from the same area could be stimulated as well that acts on a receptor, either its own or through IGF stimulation.
Accordingly, pursuant to foe present invention, it was discovered that, a ileal brake hormone releasing substance composed of GRAS compliant ingredients is effective in treating noninsulin dependent diabetes mellitus, pre-diabetic symptoms, and insulin resistance, with no side effects, by acting to suppress insulin resistance, lower/stabilize blood glucose, and therefore could be used in heating all form of insulin resistance as per NIDDM, polycystic ovary as well as type b insulin resistance.
GLP-1, an insulinotropin, hormone released from the intestinal L cells in response to nutrient ingestion, has been extensively reviewed with respect to beta-cell function. GLP-1 is both a gut-derived hormone and a neurotransmitter synthesized in the brain. Early reports suggested that GLP-1 acts in the periphery to promote insulin secretion and affect glucose homeostasis, whereas central GLP-1 reduces food intake and body weight. However, current research indicates that in fact, GLP-1 in each location plays a role in these functions. There is substantial evidence for involvement of peripheral and brain GUM in food intake regulation and glucose homeostasis and proposes a model for the coordinated actions of GLP-1 at multiple sites. (19) However, GLP-1 receptors are abundant in many other tissues. Thus, the function of GLP-1 is not limited to the islet cells, and it has regulatory actions on many other organs. For example, it has been suggested that GLP-1 may have benefit in Congestive Heart Failure (20). GLP-1 has the ability to modulate myocardial glucose uptake and thereby make an impact on cardio protection, (This is for improving muscle function and heart) Glucose-insulin-potassium (GIK) infusions have been studied for decades, with conflicting results regarding benefit in acute myocardial infarction. Based on the same concepts, GLP-1 has recently been, demonstrated to be a more effective alternative in left ventricular (LV) systolic dysfunction (20).
A review of published, peer-reviewed medical literature (1987 to September 2008) on the extra pancreatic actions of GUM was performed (21). The extra pancreatic actions of GLP-1 include inhibition of gastric emptying and gastric acid secretion, (this is to help in decreasing acid secretion and prevention of cancer of the esophagus) thereby fulfilling the definition of GLP-1 as an enterogastrone. Other important extra pancreatic actions of GLP-1 include a regulatory role in hepatic glucose production, the inhibition of pancreatic exocrine secretion, cardio protective and cardio tropic effects, and the regulation of appetite, and stimulation of afferent sensory nerves. The primary metabolite of GLP-1, GLP-1 (9-36) amide, or GLP-1m, is the truncated product of degradation by dipeptidyl peptidase-4. GLP-1 has insulinomimetic effects on hepatic glucose production and cardiac function. Exendin-4 present in the salivary gland of the reptile, Gila monster (Heloderma suspectum), is a high-affinity agonist for the mammalian GLP-1 receptor. It is resistant to degradation by dipeptidyl peptidase-4, and therefore has a prolonged half-life. In conclusion, GLP-1 and its metabolite have important extra pancreatic effects particularly with regard to the cardiovascular system and insulinomimetic effects with respect to glucose homeostasis. These effects may be particularly important in the obese state. (21).
Given the above importance of GLP-1 and the effect of increasing its levels even higher, the use of a DPP-IV inhibitor in conjunction with an orally administered ileal brake hormone releasing substance as disclosed herein should work much better than die peripherally injectable GLP-1 medications that lack the primary portal concentration that control blood glucose and hepatic glucose release as well as insulin secretion and mesenteric fat use, acting in a physiological way will prevent complications and side effect and improve outcome. Therefore the use of Brake™ with DPP-IV inhibitors available on the market can target type 2 diabetes and prediabetes and serve as a pharmaceutical medicament more powerful and natural with fewer side effects in metabolic syndrome manifestations.
By contrast, food-related stimulation of GLP-1 is hypo-responsive or even absent in obese patients. The ileal brake is down regulated, Marks et al. also showed a remarkable absence of GLP-1 response to oral glucose in obese patients (22), indicating a down-regulation of the ileal brake pathway in the pathogenesis of obesity. On the other hand, obese patients who undergo bariatric surgery lose weight gradually by suppression of appetite. They also experience very positive impact on glucose levels in the blood and improvement in insulin resistance. One possible explanation for all of these effects is a remarkable reactivation of the dormant ileal brake pathway by bariatric surgery, just as would be expected from the experiments delivering high amounts of Brake or its components to the ileum via an enteric tube (23,24). Thus, the present invention also relates to its use as an alternative therapy or concomitant therapy or pretherapy or post therapy to bariatric surgery)
In 1996 it was postulated that this stimulation happens via neurotransmission (25), and to some extent involves GIP indirectly via neuron-stimulation of the ileal brake hormones. The effect could be inhibited by lowering neuron stimulation using blockers. Others have challenged these findings, and alternatively proposed that the ileal brake effects are mediated directly by the L-Cells that are found throughout the intestinal tract. In fact they argue that the effect on L-Cells coexists with the GIP hormones in the upper jejunum and with PYY in the lower gut.
Fractionation experiments with enteroglucagon resulted in isolation of GLP-1 and GLP-2. Because of its insulin activity GLP-1 is used to treat diabetics, and was noted to have significant weight loss properties. Analogues to GLP-1 made available for treatment of diabetes such as Exenatide (Byetta) are associated with favorable glucose control and appetite suppression associated weight loss. Other hormones in the ileal brake pathway, such as PYY analogues, were also made available and trials were also designed to use these in the treatment of human obesity.
Holst and colleagues (2006) published a detailed review on the action of GLP-1 on different parts of the body to include the muscles, nervous system, the heart as well as the pancreas the liver intestine and brain (26). GLP-1 was shown to be a powerful regulator of food intake in humans at physiological levels (27,28). GLP-2 targets growth and regeneration of the enteric organs, therefore acting as a growth factor hormone which serves in the recovery of the body from injury (32-37). This will help the body to recover from injury related to event such as chemotherapy, radiation, mechanical injuries such as surgeries or trauma, or infections. PYY was shown to induce satiety as well as to suppress acid secretion combined with GLP-1, and act on motility significantly (38,39). PYY was also tested by both injection and nasal administration, but was itself unsuccessful for prevention and treatment of obesity. Some studies suggest that stimulation of all the hormones of the ileum simultaneously worked synergistically to suppress appetite and regulate both glucose and insulin, and the result of this synergy was notable by its actions at lower doses and mainly on the portal system.
Beside the above we noted that triglyceride levels decreased even more significantly tan above liver enzymes indicating that the present invention can be used to target steatohepatitis as well as hyper triglyceride. On the topic of liver injury and fatty liver disease, one patient under treatment for Hepatitis C genotype 1a, experienced a reversal in the virus count during a conventional therapy with interferon and ribavirin therapy that usually is interpreted as resistance of the virus to treatment hack to a normal responsive trend, indicating a change in the patient's immune response to the therapy.
On another subject, a female patient under treatment for autoimmune hepatitis worsening liver enzymes and meld score on steroids and cellcept, improved her liver enzymes again indicating an improvement and change in the patient immune system indicating a more generalized indication for liver disease beyond the metabolic condition or another explanation that all liver diseases have a common important factor in response to any injury that relate to the way the liver respond to injury.
Injection of analogues of GLP-1 peripherally is a familiar approach in the treatment of diabetes, and produces appetite suppression in a manner similar to Aphoeline/Brake treatment. However, the properties of peripheral GLP-1 include a different biodistribution pattern and a short half-life of approximately 3 minutes. The majority of the dose does not enter the portal system as it would if GLP-1 was induced by GI tract stimulation and with peripheral administration less than 15% will go through the liver to the periphery. While exogenous use of enteric ileal brake hormones is demonstrated to have an effect on appetite suppression, the idea of using an oral formulation to reset, modulate or stimulate the endogenous ileal brake in the lumen of the GI tract has not been tried before, other than by RYGB surgery. The novel action of a formulation on the ileal brake pathway is of major advantage over peripheral subcutaneous injection, because this pathway is optimally activated LOCALLY in the distal small bowel. There are more substances than GLP-1 released with ileal brake activation, and when stimulated properly these ileal brake hormones act synergistically and in a highly complementary manner, which both avoids side effects associated with only one of them administered parenterally, and produces: an optimal exposure of the hormones to the pancreas, liver and the anterior GI tract. Thus the peripheral injection approach to use of GLP-1, although proven to have appetite suppression, is partly a delivery site problem. For example, subcutaneous injection of GLP-1 mimetic, at supra-physiological levels, does not confer the advantages of portal application of lowered amounts. Thus the liver and pancreas effects are not beneficial; only the brain appetite suppression axis is activated by peripheral subcutaneous injection. Furthermore there are GLP-1 receptors in non-target organs like the heart and kidney, and these may explain some, of the recently noted side effects of Exenatide. Thus the portal system is where most of the action is taking place, and activation of the local ileal brake pathways lead to the full complement of benefits beyond appetite suppression. With oral administration of Brake, there is appetite suppression, but also beneficial effects on glucose control, insulin pathways, re-set pancreatic glucose sensors, hepatic glycogen storage and glucose release, and mobilization of adipose tissue.
The actions controlled by Aphoeline/Brake and the biomediators released therefrom are in the GI tract itself all the way from the esophagus to the rectum. Another problem with peripheral GLP-1 is the development of antibodies to the peptide within one year and up to 40% of the treated patients with Exenatide. The other side effects of Exenatide include pancreatitis and renal failure associated with the treatment. These should not occur with local release of GLP-1 from use of Brake.
On reviewing the literature in regard to appetite control and obesity the mainstream approach has been caloric counting and exercise. Excessive caloric intake has been linked to a psychological problem. As a consequence, from the patient viewpoint they are either addicted to food without will power or the patient is not sufficiently active to compensate for the intake of calories (49). Though valid, these statements do not give an accurate picture of the problem afflicting the large proportion of patients that appear to be very balanced psychologically and despite their best efforts are not capable of losing weight. Some reviews suggest that people under stress tend to lose less weight than people under less stressful situations, ascribing cortisol as the etiological factor. Other studies using a rat model (48) suggest that obesity is predetermined and one will tend to go back to the genetic curve with age.
We do know that certain conditions, including diabetes, hypertension, insulin resistance, commonly used antidepressants and anti-psychotics are associated with weight gain. The effect of bariatric surgery on patients with obesity and concomitant diabetes also seem to be mediated thru the suppression of appetite centrally after local GI activation of the ileal brake pathway. There is the likelihood that use of Brake in combination with centrally active compounds that stimulate appetite, such as olanzapine (Zyprexa), will offset the weight gain disadvantage of these drugs, giving rise to combination products such as ZyprexaBrake. The mechanism of action is not psychological as oral caloric intake and energy expenditure, since patients with a RYGB surgery for obesity have improved appetite control compared to people that undergo a lap band surgery. The effectiveness of RYGB surgery is also related to the connection site of the bypass. Make it too short and severe malabsorption results, while if the loop is too long the patient does not lose weigh t. The site of the surgical connection clearly influences the activation of the ileal Brake. Another consistent observation is the favorable weight loss action of Liraglutide in spite of no major changes in patient behavior or lifestyle (29).
The other approach to the treatment of obesity is to try to bypass different systems like providing medications that work directly on the appetite control center by different medications that are available on the market. The different side effects that will have to be dealt with include hypertension, stroke, addiction, seizures, cardiac arrhythmias and coronary events, pulmonary hypertension, severe depression, suicide, and insomnia. Even when the patient loses weight, there is a rebound off medications associated with binge eating and the patient ends up being either recycled in the system for another course of therapy in weight control centers, or gaining more weight than he started with, putting him at risk that could be higher than the baseline due to the severe weight fluctuations over short periods of time.
Vildagliptin is a selective dipeptidyl peptidase IV inhibitor that augments meal-stimulated levels of biologically active glucagon-like peptide-1. Chronic Vildagliptin treatment decreases postprandial glucose levels and reduces hemoglobin A1C in type 2 diabetic patients. However, little is known about the mechanism(s) by which Vildagliptin promotes reduction in plasma glucose concentration. METHODS: Sixteen patients with type 2 diabetes (age, 48+/−3 yr.; body mass index, 34.4+/−1.7 kg/m2; hemoglobin A1c, 9.0+/−7-0.3%) participated in a randomized, double-blind, placebo-controlled trial. On separate days patients received 100 mg Vildagliptin or placebo at 1730 h followed 30 min later by a meal tolerance test (MTT) performed with double tracer technique (3-(3)H-glucose iv and 1-(14)C-glucose orally). RESULTS: After Vildagliptin, suppression of endogenous glucose, production (EGP) during 6-h MTT was greater than with placebo (1.02+/−0.06 vs. 0.74+/−0.06 mg·kg-1·min-1; P=0.004), and insulin secretion rate increased by 21% (P=0.003) despite significant reduction in mean plasma glucose (213+/−4 vs. 230+/−4 mg/dl; P=0.006). Consequently, insulin secretion rate (area under the curve) divided by plasma glucose (area under the curve) increased by 29% (P=0.01). Suppression of plasma glucagon during MTT was 5-fold greater with Vildagliptin (P<0.02). The decline in EGP was positively correlated (r=0.55; P<0.03) with the decrease in fasting plasma glucose (change=−14 mg/dl). CONCLUSIONS: During MTT, Vildagliptin augments insulin secretion and inhibits glucagon release, leading to enhanced suppression of EGP. During the postprandial period, single dose of Vildagliptin reduced plasma glucose levels by enhancing suppression of EGP. (40)
Other approaches to weight loss target absorption, create states of malabsorption, produce stool incontinence, and may result in fatty liver another undesirable effects (51).
Based on these premises leaders in the field started to emphasize a more natural GI tract based approach to weight loss that would involve all the endogenous mechanisms that regulate caloric intake and body weight. The goal was to lose more weight with fewer side effects, and the standard is RYGB Surgery. A recent review of approaches to this problem eloquently summarizes the field (17, 41-44). The focus is shifting to the ileal brake pathways that are using the body natural signals; the gut hormones for future research of obesity pharmacotherapy (45,46). It was discovered that RYGB should be the standard for comparison of the actions of Aphoeline/Brake, considering both, physiology and mechanistic pharmacology. The RYGB and the oral formulation were shown, for the first time, to be acting in a nearly identical manner. The only difference is greater weight loss tram RYGB, but that was to be expected because the size of the stomach is reduced dramatically in RYGB, while there is no change in stomach size when taking Brake.
Based on our clinical observations, there is a component of hunger and obesity that is visceral and unconscious. To a certain extent, these effects are unknown to the patient, making it very difficult for the person to control appetite. The person at the time will be trying to replace the lack of visceral perception with an alternative voluntary conscious awareness resulting in continuous monitoring of the calories and input output as well as calories used and activity at all time to control the weight. This is difficult, and often causes frustration to those attempting to lose weight in this manner. The action of the ileal Brake is involved in the Selective Modulation of Appetite, and control of appetite in this both conscious and unconscious state. To some extent, the lower GI tract influences appetite for foods that the body needs, and the tuning of these appetite pathways is controlled both by consumption and by expenditure. With respect to glucose control, the teachings of the supply side model amplify the understanding of these pathways and their contribution to long term weight and to control of Type 2 diabetes via diet and exercise. The surprising observation was the impact of the ileal brake hormones on control of type 2 diabetes, and the homology between RYGB and Brake.
Going back to the literature trying to figure out the different responses of the body to food between normal and overweight or obese patients, the only significant abnormality that was reported, is the response of the ileal break to the intake of the mixed meal (17, 22), and more specific to carbohydrates. Therefore it seems the natural appetite suppressive pathways become tolerant to the intake of carbohydrates. This partially explains the success of the Adkins diet, even though in this case there arene demonstrable differences in the anatomy or histology of those two groups, except in rare cases of severe morbid long term obesity associated with atrophy of the ileum. Given the fact that food delivered to that part of the intestine is capable of stimulating diose hormones independently of oral intake and the fact that the ileal stimulation during a mixed meal can be inhibited by suppressing the neurotransmission, raise the possibility that the problem seems to be about the transmission of the signal from gut to brain. It is possible that a reset of a carbohydrate-tolerant ileal brake pathway will re-set the appetite center and renews the feedback loop that interrupts eating, all without progression to a metabolic syndrome. Therefore if we are able to directly stimulate die ileum in the manner of RYGB with an orally administered formulation, we should be able to restore the ileal brake signal and at least give the patient some help in restoring visceral signals that measures the food intake.
These visceral signals are not only important to control of metabolic syndrome abnormalities but as reported in review articles (34,44) these hormones are extremely beneficial to the patient. Their absence during down-regulation could be what the patients am seeking unconsciously when they overeat. Since these hormones are also very important in the homeostasis of the insulin and glucose levels they will help tremendously in the use is of the reserves that are already present Finally there is new evidence that gut derived inflammation, itself an effect of food and intestinal bacteria, is regulated by the hormones released by the ileal brake pathway, and that for the first time RYGB surgery and oral administration of Brake control these long term inflammation pathways. When out of control, these pathways lead to metabolic syndrome manifestations such as atherosclerosis, and perhaps contribute to deposition of metabolic byproducts such as amyloid in the brain, thought to be an important pathway in Alzheimer's disease. In this manner use of Brake would improve atherosclerosis or Alzheimer's disease, beneficial effects already attributed to RYGB surgery.
By stimulating the hormones naturally with Aphoeline/Brake™ we are delivering the majority of the hormones where they belong in the portal system, where they have the most powerful impact on the pancreas and the liver. We were also encouraged by the fact that RYGB surgery for obesity is capable of stimulating those hormones in all patients, indicating that the innate ability of these hormones to respond is still present.
We set a goal to stimulate the ileal hormones with an oral formulation of GRAS ingredients, created to become an ileal brake hormone releasing substance that mimics the action of RYGB surgery. The data from a comparison of Aphoeline/Brake with RYGB are compelling and the stimulation of the ileal brake pathway seems independent of age or weight or diabetes. This establishes the intestine still functions despite obesity, and the problem seems to be in the down-regulation of the signaling from the ileum. (Another confirmation to that statement comes from the RYGB surgical procedure that in appropriate individual triggers the same process).
What we discovered from oral formulations given to modulate ileal brake hormone release, is that local stimulation of the ileum in this manner has a very powerful effect on the glucose and insulin homeostasis, leading to a rapid decline in of insulin resistance. Insulin resistance is the first major biomarker to change in response to either the oral use of Brake or to RYGB surgery. We discovered that the ileal brake pathway is not a means of further stimulating insulin, but rather a reduction of glucose supply side delivery leading to a reduction of insulin resistance that occurs well before the patient begins to lose weight. This is also consistent, with the data from RYGB surgery, where the reduction in insulin resistance occurs within a few hours of surgical anastomosis, again much earlier than any weight loss.
The more powerful effect on steatohepatitis, seen by decrease of the enzymes level to normal within 3-4 weeks of treatment with Aphoeline/Brake need to be studied on a much longer duration to confirm the trend and the gains, but it seems from the reduction in endotoxin, inflammation, insulin resistance and the trend to normalize triglyceride and cholesterol as well as to the surprising improvement of all parameters including platelets that die trend is true. Similar platelets trend is seen in cirrhotic patients (non-published data).
Based on the recent publication of Liraglutide and weight loss (29), the GLP-1 family of gut hormones will induce weight loss but in a different way than expected, the weight loss is slow and happens after other parameters start to improve. Weight loss is insidious, just like weight gain, and occurs on a rather unconscious level. The pathway is re-activated after being dormant and the distal caloric signals are now once again responded to in the ileum.
The advantage of having an oral stimulation of all the ileal hormones is the synergistic effect of the hormones that were meant to be stimulated together in a broad pathway beyond any individual component. The fact that these hormones are released in the portal system that seems to be the center of all metabolism except the muscles and the brain, the fact that the highest concentration of these hormones is in the portal system make our stimulation much less intrusive and more efficient than the peripheral administration of such hormones.
The mechanism for the suppression of insulin resistance needs further investigation. Although we showed that the IGF system is stimulated, we do not feel this is the only answer to the question; other peptides as well as other cellular receptors such as the RR receptors need to be investigated as part of the equation. In the next section, we prioritize our future work in tins direction.
Given that the most natural way to stimulate those hormones is the use of an oral formulation for gut stimulation of the ileal brake pathways, we devised a project and a product to both stimulate and then reset the ileal brake in patients. The major goals were:
1. To establish proof of concept with oral activation of the ileal brake pathways, whereby an oral pill containing food content that is protected with an enteric-coating mechanism, could deliver this food content: to the distal ileum, and thereby stimulate ileal brake hormones.
2. To demonstrate that stimulation of the ileal brake with this formulation is reproducible and can cause the released ileal hormones to reach significant levels physiologically in humans.
3. To determine a time related pattern of response to stimulation of the ileal brake and to use the local enteric stimulation as means of re-setting the ileal brake of obese patients.
4. To demonstrate stimulation of the ileal brake in overweight and obese patients.
5. To demonstrate that the increase in the hormones of the ileal brake cause weight loss in obese patients by regulating gut-brain signaling and therefore lower appetite.
6. To study the interactions between ileal brake hormones and systemic effects, such as control of blood glucose, insulin homeostasis, and appetite control.
7. To establish doses, administration times and optimal schedules for Aphoeline/Brake™ in treated patients with obesity.
This project was designed to reset a biological process regulating appetite. It tests an endogenous pathway that appears to be hypo-responsive obese patients. It is believed that a reset of the ileal brake mimics the effect of bariatric surgery in the obese patient, without exposing the obese patients to the risks of surgery. If successful, the product will use an existing pathway that protects from the harmful effects of metabolic syndrome, and the associated controls and feedback loops, avoiding complications and side effects. Use of Brake™ will help the body regain control of the intestinal factors that regulate ingested nutrients and weight. Furthermore, giving patients control of an unconscious pan of appetite control, a pathway dial is very difficult to deal with at the conscious level, will make it easier for them to follow a diet and lose weight There is no evidence that the hypo-responsive ileal brake in obese patients is an organic defect that cannot be subject to external regulation, although it is theoretically possible since some patients do not respond to bariatric surgery.
As a starting point we needed to calculate the amount of food needed to deliver to the ileum. For that purpose we decided to use carbohydrate as a starting solution. Carbohydrate is a significant stimulus to the ileal brake mechanism (12), and it was easy to monitor for any absorption or failure of the pill by checking the blood glucose level. Finally, absorption of carbohydrate stops much sooner than fat and gives us more room for the initial testing of the oral formulation.
Based on the above we have to calculate the right amount of calories to be delivered to the ileum. We decided to proceed with testing the minimal amount of carbohydrate needed to stimulate insulin and be visible in the blood stream; we termed this a minimal metabolic unit. The drought behind it was that if the upper gut was able to perceive it as food, the lower gut that is supposed to monitor malabsorption should be able to react to it as a signal of malabsorption. It was determined that the unit should be between 8 to 15 gm of carbohydrate. The amount used in the direct ileal stimulation experiments was around 15 gm (12).
The second task was to have the coating for the pill to deliver the carbohydrate to the ileum without proximal small bowel absorption. This required a slow release formulation to avoid an osmotic side effect.
Because of the amount of carbohydrate involved in re-setting the ileal brakes the goal was to decrease the number of the pills, starting at 18 and decreasing the number to a manageable level of 7 per day. The formulation and dose finding experiments started in 2003, and by 2008 we had arrived at 4-5 different formulations that withstood these in-vitro challenges and were ready for testing.
Three trials were conducted with pilot formulations to arrive at the components of Aphoeline (pursuant to the formulations, provided above). After informed consent front healthy volunteers, monitored at all times medically the pills were given after an overnight fasting state and blood work was drawn on an hourly basis for 10 to 12 hours testing. Measured were the peptide ileal brake associated hormones and their associated biomarkers: blood glucose, insulin, c-peptide, and in the last tests IGF-1, IGF-2. Patients were allowed to drink water ad libitum. The samples were drawn according to the recommendations of the various specialized labs by professional registered nurses, and the blood was handled on the premises by a reference lab (which one) immediately on withdrawal, each tube coded accordingly packaged on dry ice and shipped overnight to the specialty labs.
Patients were separated in different groups. The groups were handled sequentially. Each subject in the group was handled simultaneously with the other elements of his group at a separate drawing station with a registered nurse, according to the time schedule. Therefore group 1 was done all at one time at the different stations from one to seven, the time frame was kept by an independent monitor to try to assure punctuality.
Initially the groups were processed and paper were filled out with a short history and physical, consent were signed, and a heparin lock was placed by the nurse at the station, then a draw at zero time was done, time was marked then the pills was given to all individual of group at the same time. The same was done to the other groups sequentially. Blood was drawn thereafter as per protocol on an hourly basis on the clock for all members of the group simultaneously, at every draw the person and vitals were assessed and blood drawn from the heparin lock, after saline flush and after discarding the first cc s to avoid high heparin concentration. For testing the GLP-1, GLP-2, and PYY was as follows: EDTA (purple top) tubes with addition of 500 micro liters of Aprotinin and 10 micro liters of DPP IV per tube. Collect blood, centrifuge within 10 minutes in a 4 degree G centrifuge. Pour off supernatant (plasma) and immediately freeze. Label and code each tube separately according to a pre organized labeling system. The tubes were Stored and ship these specimens at −70 C. The Insulin, C-peptide and glucose were collected in SST tubes, spun and sent to the local national lab.
Heparin lock, after saline flush and after discarding the first cc s to avoid high heparin concentration. The blood was placed in 2 separate tubes from the same draw to assure redundancy and control, in Vacutainer tubes containing protease inhibitors (EDTA, Aprotinin, and DPP IV inhibitor) cocktails. After blood collection and centrifuged in refrigerated centrifuge, in those tubes, then transfer the 2.5 ml plasma to a container or combine two plasmas from the same subject at “same time point” into a 6 ml container. To freeze, labeled and code each tube separately according to a pre organized labeling system then ship in dry ice as soon as possible to the peptide labs measurement preferably overnight.
Results were reported from the reference lab and decoded back in standard excel format, and forwarded to us for analysis.
The hormone data set was statistically analyzed; the results are described in the next section.
Aphoeline has been developed after testing a sequence of formulations and careful statistical analyses of the blood test results. Testing was done at three different times with three different formulations, as shown in Table 1:
The R software package for statistical computing was used for all statistical analyses and data visualization.
Results for Subjects with Elevated Glucose and/or Insulin Levels
The levels of Glucose, C-Peptide and Insulin were plotted against time for a subset of the data set generated during testing, for which initial Glucose and/or Insulin levels are elevated. The levels of Glucose, C-Peptide and Insulin all return to normal for subjects taking any of the throe Aphoeline formulations [Alpholine-0, Alpholine-1, and Alpholine2].
Weight Loss Associated with Positive Side Effects
Injection of analogue of GLP-1 peripherally is a familiar approach in the treatment of diabetes, and produces appetite suppression in a manner similar to Aphoeline treatment. However, the properties of peripheral GLP-1 include a different distribution pattern and a short half-life of approximately 3 minutes. The majority of the dose docs not enter the portal system as it would if GLP-1 was induced by GI tract stimulation and with peripheral administration less than 15% will go through the liver to the periphery. While exogenous use of enteric ileal brake hormones is demonstrated to have an effect on appetite suppression, the idea of resetting the endogenous ileal brake in the lumen of the GI tract has not been tried before, other than by bariatric surgery. The ileal brake pathway is optimally activated LOCALLY in the distal small bowel, and when stimulated properly these ileal brake hormones act synergistically and in a highly complementary rammer, which both avoids side effects associated with only one of them administered parenterally. The drawback to the peripheral injection approach of GLP-1, although proven to have appetite suppression, is partly a delivery site problem. For example, subcutaneous injection of GLP-1 mimetic, at supra-physiological levels, does not allow the advantages of portal application of lowered amounts. Thus the liver and pancreas effects are not beneficial; only the brain appetite suppression axis is activated. Furthermore there are GLP-1 receptors in non-target organs like the heart and kidney, and these may explain some of the recently noted side effects of Exenatide. Thus the portal system is where most of the action is taking place, and activation of the local ileal brake pathways lead to the full complement of benefits beyond appetite suppression. With oral administration of Aphoeline, there is appetite suppression, but also beneficial effects on glucose control, insulin pathways, re-set pancreatic glucose sensors, hepatic glycogen storage and glucose release, and mobilization of adipose tissue.
The actions controlled by Aphoeline are in the GI tract itself all the way from the esophagus to the rectum. Another problem with peripheral GLP-1 is the development of antibodies to the peptide within one year and up to 40% of the treated patients with Exenatide. The other side effects of Exenatide include pancreatitis and renal failure associated with the treatment.
On reviewing the literature in regard to appetite control and obesity the mainstream approach has been caloric counting and exercise. Excessive caloric intake has been linked to a psychological problem. As a consequence, from the patient viewpoint they are either addicted to food without will power or the patient is not sufficiently active to compensate for the intake of calories (49). Though valid, these statements do not give an accurate picture of the problem afflicting the large proportion of patients that appear to be very balanced psychologically and despite their best efforts are not capable of losing weight. Some reviews suggest that people under stress tend to lose less weight than people under less stressful situations, ascribing cortisol as the etiological factor. Other studies using a rat model (48) suggest that obesity is predetermined and one will tend to go back to the genetic curve with age.
We do know that certain conditions, including diabetes, hypertension, insulin resistance, commonly used antidepressants and anti-psychotics are associated with weight gain. The effect of bariatric surgery on patients with obesity and concomitant diabetes also seem to be mediated thru the suppression of appetite centrally after local GI activation of the ileal brake pathway. The mechanism of action is not psychological as oral caloric intake and energy expenditure, since patients with a bypass surgery for obesity have improved appetite control compared to people that undergo a lap band surgery. The effectiveness of bariatric surgery is also related to the connection site of the bypass. Make it too short and severe malabsorption results, while if the loop is too long the patient does not lose weight. Another consistent observation is the favorable weight loss action of Liraglutide in spite of no major changes in patient behavior or lifestyle (29).
The other approach to the treatment of obesity is to use medications that work elsewhere than on the appetite center, evoking actions by different pathways. The different side effects that will have to be dealt with include hypertension, stroke, addiction, seizures, cardiac arrhythmias and coronary events, pulmonary hypertension, severe depression, suicide, and insomnia. Even when the patient loses weight, there is a rebound off medications associated with binge eating and the patient ends up being either recycled in the system for another course of therapy in weight control centers, or gaining more weight than he started with, putting him at risk that could be higher than the baseline due to the severe weight fluctuations over short periods of time.
Vildagliptin is a selective dipeptidyl peptidase IV inhibitor that augments meal-stimulated levels of biologically active GLP-j. Chronic Vildagliptin treatment decreases postprandial glucose levels and reduces hemoglobin A1C in type 2 diabetic patients. However, little is known about the mechanism(s) by which Vildagliptin promotes reduction in plasma glucose concentration. METHODS: Sixteen patients with type 2 diabetes (age, 48+A3 yr.; body mass index, 34.4+/−1.7 kg/m2; hemoglobin A1c, 9.0+A0.3%) participated in a randomized, double-blind, placebo-controlled trial. On separate days patients received 100 mg Vildagliptin or placebo at 1730 h followed 30 min later by a meal tolerance test (MTT) performed with double tracer technique (3-(3)H-glucose iv and 1-(14)C-glucose orally). RESULTS: After Vildagliptin, suppression of endogenous glucose production (EGP) during 6-h MTT was greater than with placebo (1.02+/−0.06 vs. 0.74+/−0.06 mg·kg-1 min-1; P=0.004), and insulin secretion rate increased by 21% (P=0.003) despite significant reduction in mean plasma glucose (213+/−4 vs. 230+/−4 mg/dl; P=0.006). Consequently, insulin secretion rate (area under the curve) divided by plasma glucose (area under the curve) increased by 29% (P=0.01). Suppression of plasma glucagon during MTT was 5-fold greater with Vildagliptin (P<0.02). The decline in EGP was positively correlated (r=0.55; P<0.03) with the decrease in fasting plasma glucose (change=14 mg/dl). CONCLUSIONS: During MTT, Vildagliptin augments insulin secretion and inhibits glucagon release, leading to enhanced suppression of EGP. During the postprandial period, a single dose of Vildagliptin reduced plasma glucose levels by enhancing suppression of EGP.(40)
Other approaches to weight loss target absorption, create stales of malabsorption, produce stool incontinence, and may result in fatty liver and other undesirable effects (51).
Based on these premises leaders in the field started to emphasize a more natural GI tract based approach to weight loss that would involve all the endogenous mechanisms that regulate caloric intake and body weight. The goal was to lose more weight with fewer side effects, and the standard is Bariatric Surgery. A recent review of approaches to this problem eloquently summarizes the field (17, 41-44). The focus is shifting to the ileal brake pathways that are using the body natural signals: the gut hormones for future research of obesity pharmacotherapy (45, 46).
Based-on our clinical observations, there is a component of hunger and obesity that is visceral and unconscious. To a certain extent, these effects are unknown to the patient, making it very difficult for the person to control appetite. The person at the time will be trying to replace the lack of visceral perception with an alternative voluntary conscious awareness resulting in continuous monitoring of the calories and input output as well as calories used and activity at all time to control the weight. This is difficult, and often causes frustration to those attempting to lose weight in this manner.
Low-glycemic index (GI) foods and foods rich in whole grain are associated with reduced risk of type 2 diabetes and cardiovascular disease. Nilsson and Holst examined the effect of cereal-based bread evening meals (50 g available starch) that varied in content of indigestible carbohydrates, on glucose tolerance and related variables after a subsequent standardized breakfast in healthy subjects (n=15). At breakfast, blood was sampled for 3 h for analysis of blood glucose, serum insulin, serum FFA, serum triglycerides, plasma glucagon, plasma gastric-inhibitory peptide, plasma GLP-1, serum interleukin (IL)-6, serum IL-8, and plasma adiponectin. Satiety was subjectively rated after breakfast and the gastric emptying rate (GER) was determined using paracetamol as a marker. Breath hydrogen was measured as an indicator of colonic fermentation. Evening meals with barley kernel based bread (ordinary, high-amylose- or beta-glucan-rich genotypes) or an evening meal with white wheat flour bread (WWB) enriched with a mixture of barley fiber and resistant starch improved glucose tolerance at the subsequent breakfast compared with unsupplemented WWB (P<0.05). At breakfast, the glucose response was inversely correlated with colonic fermentation (r=−0.25; P<0.05) and GLP-1 (r=−0.26; P<0.05) and positively correlated with FFA (r=0.37; P<0.001). IL-6 was lower (P<0.01) md adiponectin, was higher (P<0.05) at breakfast following an evening meal with barley-kernel bread compared with WWB. Breath hydrogen correlated positively with satiety (r=0.27; P<0.01) and inversely with GER (r=−0.23; P<0.05). The authors concluded from these experiments that composition of indigestible carbohydrates of the evening meal may affect glycemic excursions and related-metabolic risk variables at breakfast through a mechanism involving colonic fermentation. The results provide evidence for a link between gut microbial metabolism and key factors associated with insulin resistance.(47)
Going back to the literature trying to figure out the different responses of fee body to food between normal and overweight or obese patients, the only significant abnormality that was reported, is fee response of the ileal brake to the intake of the mixed meal (17,22), and more specifically to carbohydrates. Therefore it seems fee natural appetite control pathways become tolerant to the intake of carbohydrates. This partially explains the success of the Adkins diet, even though in this case there are no demonstrable differences in the anatomy or histology of those two groups, except in rare cases of severe morbid long term obesity associated with atrophy of the ileum. Given the fact that food delivered to that part of the intestine is capable of stimulating those hormones independently of oral intake and the fact that fee ileal stimulation during a mixed meal can be inhibited by suppressing fee neurotransmission raise the possibility that the problem seems to be about the transmission of the signal from gut to brain. It is possible feat resets of a carbohydrate tolerant ileal brake pathway, will re-set the appetite center and renew the feedback, loop that interrupts eating, all without progression to a metabolic syndrome. Therefore if we are able to directly stimulate fee ileum we should be able to restore fee ileal brake signal and at least give the patient some help In restoring visceral signals that measures the food intake.
These visceral signals are not only important to signal satiety but as per reported reviews (34,44) these hormones are extremely beneficial to the patient. Their absence during down-regulation could be what the patients are seeking unconsciously when they overeat, energy improve muscle, liver, intestine stomach, nerve and heart. Since these hormones are also very important in fee homeostasis of fee insulin and glucose levels they will help tremendously in the use is of the reserves that are already present.
By stimulating the hormones naturally with Aphoeline/Brake™ we are delivering the majority of the hormones where they belong in the portal system, where they have the most powerful impact on inflammation that leads to metabolic syndrome complications. We were also encouraged by the fact that the bypass surgery for obesity is capable of stimulating those hormones in all patients, indicating that the innate ability of these hormones to respond is still present.
We set a goal to stimulate the ileal hormones with an oral natural agent consistent of a ileal brake hormone releasing substance. The data are compelling and the stimulation of the ileal brake pathway seems independent of age or weight or presence of type 2 diabetes. This demonstrates that the intestine still functions despite obesity, and the problem seems to be in the down-regulation of the signaling from the jejunum, which we interpret as a need to wake up the ileal brake. The ileal brake can be awakened either by RYGB surgery or oral administration of Brake™.
What we discovered from these stimulation that it have a very powerful effect on the glucose and insulin homeostasis not consistent with the assumption that these peptides work only by stimulation of the insulin but mainly through, reducing insulin resistance as well long before they achieve weight loss. This is also consistent with the data from bypass surgery.
The more powerful effect on steato-hepatitis seen by decrease of the hepatic enzyme levels to normal within 3-4 weeks need to be studied on a much longer duration to confirm the trend and the gains, but it seems that activation of the ileal brake produces many beneficial effects on metabolic syndrome including the decrease in inflammation, insulin resistance, the trend to normalize triglyceride and cholesterol as well as surprising improvement of all parameters including platelets. Similar platelets trend is seen in cirrhotic patients (non-published data).
Based on the recent publication of Liraglutide and weight loss(29), the GLP-1 family of gut hormones will induce weight loss but in a different way than expected, the weight loss is slow and happens after other parameters start to improve. Weight loss is insidious, just like weight gain, and occurs on a rather unconscious level.

The fact that these hormones are released In the portal system that seems to be the center of all metabolism except the muscles and the brain, the fact that the highest concentration of these hormones is hi the portal system make our stimulation much less intrusive and more efficient than the peripheral administration of such hormones.
The suppression of insulin resistance need further investigation even though we showed that the IGF system is stimulated, we do not feel this is the only answer to the question; other peptides as well as other cellular receptors such as the RR receptors need to be investigated as part of the equation. In the next section, we prioritize our future work in this direction.
The stimulation of the ileal hormones with Brake™: present opportunities and challenges.
1, A continuing priority is to improve the ileal brake stimulation potency with further adjustments of the formulation content and the ileal delivery system.
2. Another priority is to develop more practical tests to document the anticipated down-regulation of the ileal brake pathway in the obese, and to demonstrate the impact of Aphoeline/Brake™ in the resetting of this pathway. This testing should be applied to study of a variety of GI diseases such as irritable bowel, and to examine the relationships between hormones and intestinal permeability, immune system and bacterial flora.
3. Third priority is to check on the long term effects of the oral stimulation on improving muscles, pancreas, suppression of acid of the stomach to reported, and determine if the epidemic of reflux and adenocarcinoma increase could be explained on the basis of these hormones deficiency or abnormal responses as reported PYY and GLP1 inhibit together gastric acid secretion 100%.
4. It is necessary to examine the effects of Aphoeline on GI motility including the esophagus and achalasia since these hormones were reported to be neurotrophic. The effect on the lung has not been studied yet, but since it improves the function of other muscles it should have a beneficial impact on the costal muscles, as well as those of the bronchi and the diaphragm.
5. Diabetes is a major target and its innocuous profile should be considered its a first line of treatment, large study and long term effect should be targeted including HbA1c, all indications that the ileal brake pathway does improve diabetes. Because of its effect on insulin resistance, other circumstances of insulin resistance should be checked as well including but not limited to polycystic ovaries.
6. We also would study the effect on the liver. Even though it helps fatty liver it seems that it effect should be checked in different conditions as well including different hepatitis as a co-adjuvant therapy.
7. We would also investigate the use of Aphoeline as a co-adjuvant therapy in bypass surgery. Assessment; of action prior to surgery to study the ileal response or to stabilize die patient and improve their gut or post op as a salvage therapy, or co-adjuvant, should be considered.
The to-do list and the excitement are limitless, especially considering that these effects were produced by a benign orally administered natural product. Reactivation of a dormant gut peptide mechanism is a means of examining the gut as well as obesity from a new perspective.
We have demonstrated the feasibility of a benign food substance delivered orally to stimulate the ileal hormones. The response appears to be sufficient to standardize the stimulation of the ileal brake hormones. Some unusual effects of that stimulation included suppression of insulin resistance, improvement in blood glucose levels, and significant early improvement in liver enzymes and lipid levels. While these beneficial effects were sustained in short term experiments, further large scale clinical testing and longer term clinical studies will be needed to confirm the persistence of these effects.
Based on our open trials, the long term effect of the Aphoeline formulation is an increase in energy levels. There was an unconscious awareness of the calorie intake and a resetting of appetite which then resulted in significant weight loss. Long term double-blind placebo controlled trials, similar to the one conducted with Liraglutide, are being planned.
A number of patients above were followed for six months to a year period following the initial studies described above (therapy continued at 7 pills—about 10 g. glucose per day via Aphoeline-2 with blood work performed weekly) to determine, what effects would be present or manifest during that time period. The following results and general trends were obtained and/or observed:
1. Insulin resistance continued to be suppressed;
2. Insulin, pro-insulin and c-peptide were brought back to normal levels;
3. Patient's weight decreased substantially;
4. Decreased triglyceride levels to normal (from 400 mg/dl to about 100-120 mg/dl);
5. Decrease liver enzymes from about 300 IU/L down to a normal level (0-85 IU/L);
6. Decreased hepatitis C-virus titers.
7. Substantially decreased α-fetal protein (from 30 ng/ml to less than 6 ng/ml).
The effects of the present invention are long-lasting and therapy may be continued for extended periods of time, resulting in favorable responses in all patients tested.

Reduction in Endotoxemia, Oxidative and Inflammatory Stress, and Insulin Resistance Following Roux-En-Y Gastric Bypass Surgery in Patients with Morbid Obesity and Type 2 Diabetes Mellitus.
Background: Roux-en-Y gastric bypass (RYGB) results in profound weight loss and resolution of Type 2 Diabetes Mellitis (T2DM). The mechanism of this remarkable transition remains poorly defined. It has been proposed that endotoxin (LPS) sets inflammatory tone, triggers weight gain, and initiates T2DM. Because RYGB may diminish LPS from endogenous and exogenous sources, we hypothesized that LPS and the associated cascade of oxidative and inflammatory stress would diminish after RYGB.
Methods: Fifteen adults with morbid obesity and T2DM undergoing RYGB were studied. Following an overnight fast, a baseline blood sample was collected the morning of surgery and at 180-days to assess changes in glycemia, insulin resistance, LPS, mononuclear cell (MNC) NFκB binding and mRNA expression of CD14, TLR-2, TLR-4, and markers of inflammatory stress.
Results: 180-days following RYGB, subjects had a significant fall in BMI (52.1±3.0 to 40.4±11.1), plasma glucose (148±4 to 101±4 mg/dl), insulin (18.5±2.2 to 8.6±1.0 mμ/ml) and HOMA-IR (7.1±1.1 to 2.1±0.3). Plasma LPS significantly reduced by 20±5% (0.567±0.033 to 0.443±0.022 EU/ml). NFκB DNA binding fell significantly by 21±8%, while TLR-4, TLR-2 and CD-14 expression fell significantly by 25±9%, 42±8%, and 27±10%, respectively. Inflammatory mediators CRP, MMP-9 and MCP-1 fell significantly by 47±7% (10.7±1.6 to 5.8±1.0 mg/L), 15±6% (492±42 to 356±26 ng/ml) and 11±4% (522±35 to 466±35 ng/ml), respectively.
Conclusions: LPS/NFκB DNA binding, TLR-4, TLR-2, and CD 14 expression, CRP, MMP-9 and MCP-1 fall significantly after RYGB. The mechanism underlying resolution of insulin resistance and 12DM following RYGB may be attributable, at least in part, to the reduction of endotoxemia and associated pro-inflammatory mediators.
Obesity, insulin resistance, and type 2 diabetes mellitus (T2DM) are associated with low-grade chronic inflammation.1-5 The inciting event linking the activation of the chronic inflammatory state to the development and/or maintenance of obesity and T2DM has not been well defined. In 2007, Cani et al demonstrated an animal model for the pathogenesis of obesity, insulin resistance, and T2DM wherein elevated circulating endotoxin, or bacterial cell wall lipopolysaccharide (LPS), exposure may set inflammatory tone, trigger weight gain, and initiate T2DM.6 LPS exposure is continuous from endogenous sources (gut microbiota)7-8 and intermittent from exogenous sources (high-fat, high-carbohydrate meals and saturated fat).9-10 The binding of LPS to the complex of CD14 and toll-tike receptor-4 (TLR-4) at the surface of innate immune cells lead to the activation of inflammatory pathways mediated by the pro-inflammatory transcription factor, nuclear factor kappa B (NFκB) and the secretion of pro-inflammatory cytokines and other mediators.11 It is thus possible that LPS may be a significant contributor to the induction and maintenance of the chronic inflammatory state hallmark to obesity and T2DM.
Roux-en-Y gastric bypass (RYGB) results in profound weight loss in a majority of patients which is accompanied by a high resolution rate of T2DM.12-15 The resolution of the diabetic state is observed within days of the procedure and well before clinically significant weight loss has occurred.7 This time course of resolution provides important evidence dial the chronic inflammatory state may be mediated by a source other titan the adipose tissue. Since LPS is a potential source of the persistent chronic inflammatory state and RYGB ‘curative’ of the insulin resistant diabetic state, we hypothesized that plasma LPS concentration would be reduced following RYGB and that this reduction would be accompanied by a similar reduction in the expression of mononuclear cell (MNC) CD14 and TLR-4 along with a reduction in NFkB binding and other markers of oxidative and inflammatory stress.
Subjects: Fifteen adult subjects with morbid obesity (body mass index≥40 kg/m2) and T2DM scheduled to undergo RYGB were included in the study. The operative technique has been described previously.16 Subjects were required to have a minimum of three months of stable ACEI/ARB, statin, and T2DM therapy, defined as no greater than a one-step dose increase or decrease (i.e. metformin from 1000 mg to 500 mg or glyburide from 10 mg to 5 mg). Insulin requirements were not permitted to change greater than 25%. Subjects were: excluded if they required chronic aspirin. NSAID'S or systemic corticosteroids. Baseline characteristics for the subjects are presented in Table 1. After an overnight fast, a baseline blood sample was collected the morning of the RYGB procedure and at 180-days to assess change in glycemia, insulin resistance (HOMA-IR), plasma LPS, MNC NFκB binding and mRNA expression of CD1:4, TLR-2, TLR-4, and other markers of oxidative and inflammatory stress (G-reactive protein [CRP], monocyte chemoattractant protein-1 [MCP-1], and matrix metalloproteinase-9 [MMP-9]). The study was approved by the Catholic Health Institutional Review Board (Buffalo, N.Y.). Each participant signed informed consent (NCT00960765).
MNC Isolation: Blood samples were collected in Na-EDTA and carefully layered on Lympholyie medium (Cedarlane Laboratories, Hornby, ON). Samples were centrifuged and two bands separated out at the top of the RBC pellet. The MNC band was harvested and washed twice with Hank's balanced salt solution (HBSS). This method provides yields greater than 95% MNC preparation.
NFkB DNA binding activity: Nuclear NFkB DNA binding activity was measured by electrophoretic mobility shift assay (EMSA). Nuclear extracts were prepared from MNC and by high salt extraction as previously described.5-17 The Active NFkB complex band was determined by incubating nuclear extract from one sample with and without antibodies against p65 or p50 (Santa Cruz Biotechnology, CA), the 2 major components of the active NFκB complex. Specific NFκB bands will be supershifted (SS) (totally or partially) and will appear at a higher molecular weight in the gel while bands that are not affected by the addition of the antibodies are considered nonspecific (NS).
Quantification of TLR4, TLR2, CD14 mid MyD88 Expression: The mRNA expression of TLR4, TLR2, CD14 mid MyD88 was measured in MNC by RT-PCR: Total RNA was isolated using commercially available RNAqueous®-4PCR Kit (Ambion, Austin, Tex.). Real Time RT-PCR was performed using Stratagene Mx3000P QPCR System (La Jolla, Calif.), Sybergreen master mix (Qiagen, CA) and gene specific primers (Life Technologies, MD), All values were normalized to a reference value calculated by GeneNorm software based on the expression of a group of housekeeping genes including actin, ubiquitin C and cyclophilin A.
Plasma Measurements: Glucose concentrations were measured in plasma by YSI 2300 STAT Plus glucose analyzer (Yellow Springs, Ohio). ELISA was used to measure plasma concentrations of insulin (Diagnostic Systems Laboratories Inc., Webster, Tex.), MMP-9 and MCP-1 (R&D Systems, MN) and CRP (American Diagnostica Inc. Stamford, Conn.). Plasma endotoxin concentrations were measured by a commercially available kit (Cambrex Limulus Amebocyte Lysate (LAL) kit, Lonza Inc. Walkersville, Md.). This assay has a sensitivity range of 0.1 EU/ml-1.0 EU/ml. Normal values from lean subjects measured in our laboratory ranged from 0.15-0.35 EU/ml. Inter and intra-assay variations for this test is <10%. Plasma samples used for LPS determination were stored in LPS-free glass tubes to prevent loss of endotoxin to plastic tubes wall. All materials used for the assay were rendered LPS-free. Plasma was diluted 10 folds and heated to 75° C. for 5 min prior to LPS measurement.
Statistical Analysis: Statistical analysis was conducted using SigmaStat software (SPSS Inc., Chicago, IL). All data are represented as mean±S.E. Change from baseline was calculated and statistical analysis was carried out using Paired t-test or Wilcoxon Signed Rank Test, where appropriate. Correlation analysis was performed using Spearman rank-order correlation between change in weight and LPS.
Results of the experiments of this example are presented in FIGS. 1EX5-4EX5 as follows.

More specifically, FIG. 5EX5 provides the results of additional regression analyses of data taken from the bariatric surgery patients. The data compilations presented in the
Anthropometric and Metabolic Changes Following RYGB: Six months following RYGB, BMI fell from 52.1±13.0 to 40.4±11.1 kg/m2 and there were significant improvements in the HbA1C and lipid profile (Table L, below). There was a significant fall in plasma concentrations of glucose (148±8 to 101±4 mg/dl), insulin (18.5±2.2 to 8.6±1.0 mμ/ml) and HOMA-IR (7.1±1.1 to 2.1±0.3) (FIG. 1EX5, P<0.05 for all). In addition, free fatty acid (FFA) concentration fell significantly by 24% (0.68±0.16 to 0.51±0.17 mM; p<0.05) and plasma transaminase concentrations (AST and ALT) fell 42% (35.6±15.0 to 20.8±9.6; U/L p<0.05) and 49% (36.5±12.8 to 18.6±13.4 U/L; p<0.05), respectively.
Medication Requirements Following RYGB: The use of antidiabetic medication was reduced over the six month follow-up period with fewer subjects requiring metformin (73 vs. 33%; p=0.036) and thiazolidinediones (47 vs. 7%; p0.036). Secretagogue (27 vs. 0%; p=0.1) and insulin-based regimens (33 vs, 20%; p=0.371), ACEI/ARB (33 vs, 20%; p=0.465), and statin (53 vs. 33%; p==0.181) use were not significantly reduced.
Effect of RYGB on Plasma LPS and Proinflammatory Mediators: The plasma concentration of LPS was reduced by 20±5% (0.567±0.033 to 0.443±0.022 EU/ml, FIG. 2EX5, P<0.05) following RYGB, The change in LPS was significantly correlated with the change in weight (r2=0.298; p=0.041). Proinflammatory mediators including CRP by 47±7% (10.7±1.6 to 5.8±1.0 mg/L), MMP-9 by 15±6% (492±42 to 356±26 ng/ml) and MCP-1 by 11±4% (522±35 to 466±37 ng/ml) also fell significantly following RYGB (
Effect of RYGB on the Expression of TLRs and CD14 in MNC: The mRNA expression of TLR4, TLR2 and CD14 fell significantly by 25&9%, 42±8% and 27±10% over a six month period following RYGB (FIG. 3EX5, P<0.05), There was no significant change in MyD88 gene expression in MNC
Effect of RYGB on NFκB DNA binding: Supershifting assay confirmed the presence of a specific active NFκB complex band (NFκB) and at least 2 nonspecific bands (NS) in the MNC nuclear extracts (FIG. 4EX5). There was a significant reduction in intranuclear NFκB DNA binding in MNC measured by the intensity of the specific band in PMS A. It fell by 21±8% below the baseline at six months following RYGB (FIG. 4EX5, P<0.05).
Our data show clearly that in association with weight toss following RYGB there is a marked reduction in plasma LPS concentration and the mRNA expression of TLR-4 and CD14 in addition to a diminution in inflammation. Since LPS binds to CD14 and TLR-4, the reduction in all three factors potentially orchestrates a reduction in LPS induced inflammation. The activation of the TLR-4 by LPS leads to downstream signaling which leads to the activation of NFkB and to increased transcription of pro-inflammatory genes. Thus, the observed reduction in LPS concentration and life associated expression of TLRs and CD14 and intranuclear NFkB binding represent a reversal of the chronic inflammatory state which characterizes obesity and T2DM. In addition to these findings, we also observed a reduction in the expression of TLR-2 which is the receptor for lipopeptides and peptidoglycans from Gram positive bacteria. In contrast, the expression of MyD88, which mediates downstream inflammatory changes following the binding of TLR ligands, was not altered.
Our previous work has demonstrated that in humans, a single high-fat, high-carbohydrate meal (910 calories; 41% carbohydrate, 42% (at, 17% protein) significantly increases plasma LPS, MNC TLR-2, and TLR-4 expressions and markers of oxidative and inflammatory stress in comparison to an isocaloric meal rich, in fruit and fiber (58% carbohydrate, 27% fat, 15% protein) over a 5 hour period.9 We have also demonstrated that it is saturated fat rather than carbohydrate that induces an increase in LPS concentration and TLR-4 expression.10 The restriction of fat consumption induced by RYGB is likely to be a significant contributor to the long-term diminution of the chronic inflammatory state, in this context, it is important to note that the indicators of oxidative and inflammatory stress increase prior to a significant increase in LPS concentration, CD14 and TLR-4 expression following the intake of a pro-inflammatory meal. Such initial increases may increase intestinal permeability and facilitate the absorption of LPS from the gut. Thus, the role of LPS-CD14-TLR-4 increment following the intake of such a meal would be in the latter phases of post prandial inflammation and also in the context of chronic excessive macronutrient intake.6 It should be noted however, that because, our findings were observed in the fasting phase we cannot definitively determine if the changes observed in LPS and inflammatory markers are derived from the interruption of the chronic excessive macronutrient intake, a persistent shift in the endogenous microbiota, or a combination of these factors. Indeed, large gastrointestinal bacterial population shifts have been demonstrated following RYGB and may further contribute to alterations in gut permeability.8 To provide greater insight as to the contribution of macronutrient intake and the endogenous flora in the maintenance of the chronic inflammatory state it is of interest to investigate if die pro-inflammatory effect of a meal alters after RYGB.
To date, bariatric surgery is the only treatment known to ‘cure’T2DM.18 It is also relevant that bariatric surgery has been shown to reduce the risk of cardiovascular events.15 Our observations following RYGB are relevant in relation to the mechanisms underlying this benefit and thus the pathogenesis of these conditions, larger studies will be required to link each of the specific factors altered by RYGB independently to insulin resistance and T2DM on the one hand and to atherosclerosis on the other. Consistent with this, there was a reversal of insulin resistance as reflected in HOMA-IR with a fall in plasma concentrations of insulin, glucose and triglycerides. These effects along with marked weight loss signal a reversal of die metabolic syndrome19 and would potentially contribute to the partial or total resolution of T2DM known to occur following RYGB. A recent study from Italy has demonstrated not only a resolution of diabetes in patients subjected to gastric bypass surgery but also a significant reduction in cardiovascular events.20 Previous studies have also shown a tendency for the resolution of T2DM or a marked reduction in the dose of insulin and other antidiabetic medications.21-22 However, it should be noted that there are other potential mechanisms, possibly involving changes in incretin physiology and behavioral response which may also contribute to the resolution of T2DM23-25 Indeed, in a recent study, it was demonstrated that following RYGB there was a significant sequential increase in GLP-1 and G1P concentrations.27 This area is fertile for further investigation.
In addition to our findings on LPS, CD14, TLR-4, and intranuclear NFkB binding, we also observed a significant reduction in plasma FFA and transaminase concentrations at six months following RYGB. Increased FFA concentrations have been shown to induce inflammatory and oxidative stress including NFkB binding while also inducing insulin resistance.28 RYGB has been shown to significantly improve characteristic histological changes of non-alcoholic fatty liver disease; (NAFLD) including steatosis, inflammation, and fibrosis.29 This is of interest because lifestyle modification and weight reduction is not uniformly accepted as an effective treatment strategy for NAFLD.30 Our observations that plasma LPS and the associated inflammatory cascade diminish following RYGB may also be relevant in relation to the pathogenesis of NAFLD and its complications of cirrhosis or liver cancer.
There are some limitations inherent in this work. We do not have appropriate controls for comparison with the patients who underwent surgery, Since patients referred for surgery and approved by their insurance companies undergo the appropriate dietary protocols and surgery almost immediately, it is very difficult to obtain parallel controls. However, the consistency of the reduction of various indices described ensures that the data are biologically significant. The other shortcoming of our work is the absence of sequential data during the 6 month period so that the evolution of the changes, described can be better understood. Such a detailed study is planned for the future.
RYGB is associated with a marked weight loss and a striking reduction in insulin resistance and indices of chronic inflammation. In addition, these improvements are accompanied by reduction in plasma LPS exposure, MNC CD14. TLR-2, and TLR-4 expression and NFkB DNA binding. The reduction in LPS exposure and the expression of pro-inflammatory mediators following RYGB may contribute significantly to the resolution of insulin resistance and T2DM. These effects may potentially protect against atherosclerotic complications.
Long-Term Stimulation of the Ileal Hormones by an Oral GRAS Compliant Agent Aphoeline. Effects on Metabolic Syndrome, Fatty Liver, Type II Diabetes and Hepatitis C.
The experiment of this example shows decreasing insulin resistance, triglycerides, liver enzymes, signaling caloric intake, using caloric reserve, and tuning body to health with every meal.
More specifically, the results show that compositions and methods' of the invention can decrease insulin resistance; maintain glucose homeostasis; decrease proinsulin, (that at times seems to be the only signal to insulin resistance); decrease liver enzymes (mainly ALT, AST, SGOT, and SGPT), either directly or secondary to decrease insulin resistance; decrease alpha-fetoprotein, likely secondary to a decrease in liver inflammation; decrease hepatitis C virus levels (direct effect by improving the immune system vs. via decrease in triglycerides), (see FIG. 23EX6); decreases triglyceride; decrease weight likely as a result of decreasing insulin resistance, improving energy and therefore activities and improve signaling to the brain; and provide a good way to approach fatty liver, prediabetes, hypertriglyceridemia obesity, insulin resistance state, metabolic syndrome in general.
The physiological response to oral chronic stimulation of the ileal hormones has not been well studied. We report the results of a pilot retrospective study on 18 patients with the following conditions, obese, prediabetes, hyperlipidemia, fatty liver with elevated liver enzymes, Hepatitis C with cirrhosis, metabolic syndrome, with normal anatomy (i.e. without intestinal or gastric surgeries) followed during chronic oral daily stimulation of the ileal hormones with Aphoeline from 4 to 16 months.
Oral chronic stimulation of the ileal hormones m all patients studied appear to help decrease the average baseline levels of insulin, proinsulin, AST, ALT, Triglycerides, HBA1c, and weight, in all cases approaching normal in a statistically significant manner. When only patients with abnormally elevated baseline levels were averaged the improvement was even more pronounced. Changes in most cases approached diose from a surgical procedure, Roux-en-Y gastric bypass (RYGB), which is considered the gold standard for cure of metabolic syndromes such as diabetes, obesity and hyperlipidemia.
Our study suggests that oral stimulation of the ileal brake hormones with Aphoeline Brake seems to be a promising way to approach problems of insulin resistance, fatty liver, prediabetes, early diabetes type II, hypertriglyceridemia obesity and metabolic syndrome in general, in recent years, the favored treatment for obesity has been RYGB surgery, although only recently has direct comparison established the superiority of this approach over conventional diabetes drug therapy (1). However, few studies have been conducted on die isolated contribution of orally enhanced ileal hormone stimulation based on the decreased gastric volume, intestinal malabsorption that restores such stimulation. We report these results, from a retrospective study on 18 patients with normal anatomy, i.e. without intestinal or gastric surgeries followed during chronic oral stimulation of the ileal hormones with Aphoeline Brake™. Chronic oral stimulation of the ileal hormones appears to help decrease insulin resistance and help in glucose homeostasis. It also decreases proinsulin, liver enzymes, mainly SGOT, SGPT (AST, ALT), alpha-fetoprotein, and triglycerides and reduces weight.
Our study suggests oral Brake™ precisely mimics RYGB and is therefore a promising way to approach metabolic syndrome problems of appetite control, fatty liver, prediabetes, associated hypertriglyceridemia, obesity, Type 2 diabetes (T2D), inflammation mediated loss of pancreatic function such as Type 1 diabetes (T1D), atherosclerosis, Hepatitis C, CHF, CORD, and metabolic syndrome in general.
The novel discovery from the 18 patients treated with Brake™ is that the effects of oral Brake™ treatment persist beyond the cessation of the Brake™ therapy for a considerable period of time (at least 3 months), implying for the first lime that chronic treatment with the oral ileal brake hormone releasing substance was creating a renewed function in visceral organs such as the GI tract, liver and pancreas. Their type 2 diabetes was not immediately returning even when the patients were no longer taking the medication. Indeed it is known or suspected that the hormone mediators of the ileal brake are capable of regenerating pancreatic beta cells and even hepatocytes, but it was completely novel to observe these effects after oral mimetics of RYGB surgery like Brake™.
Blood levels of ileal hormones like gastrin, secretin, gastric inhibitory polypeptide (G1P) and cholecystokinin (CCK-8), as well as GLP-1, glucagon like peptide PYY and Oxyntomodutin, are known to increase after a meal in a healthy individual but GLP1 and ileal hormones levels fail to increase normally in obese and T2D patients(2). L-cells are the major cells of the intestinal mucosa involved in releasing the ileal hormones, following stimulation by simple carbohydrates and emulsified fat content of food in the intestinal lumen. L-cells are mainly concentrated in the ileum in most species with very few cells present proximal to the ligament of Treitz in humans and other primates (3-5). A considerable number of ileal cells are also present in the proximal colon, in glicentin granules. Ileal brake hormones play a key role in regulating insulin secretion and glucose homeostasis, as well as reducing food intake and body weight (3, 6-13). Because various commercial products considered GLP-1 analogs, such as Exenatide and Liraglutide, stimulate insulin secretion in T2D patients after peripheral injection, it was concluded that the main action of GLP-1 (5) and the ileal hormones was a backup insulin hormone that stimulates insulin as a response to food in a physiological setting. Acute food stimulation of the Ileal hormones will, in fact, suppress insulin resistance and thus help in decreasing plasma glucose levels protecting pancreatic exhaustion, as well as preventing reactive hypoglycemia rather than stimulating insulin secretion. It is however, considerably more complicated, because the ileal brake hormones clearly regulate chronic inflammatory processes that lead to fatty liver and pancreatic insufficiency, thus being responsible for both optimal nutrition but also for maintenance functions on the enteric organs themselves
As pointed out by Drucker, peptide hormones are secreted from endocrine cells and neurons and exert their actions through activation of G protein-coupled receptors to regulate a diverse number of physiological systems including control of energy homeostasis, gastrointestinal motility, neuroendocrine circuits, and hormone secretion. The glucagon-like peptides, GLP-1 and GLP-2 are prototype peptide hormones released from gut endocrine cells in response to nutrient ingestion that regulate not only energy absorption and disposal, but also cell proliferation and survival. GLP-1 expands islet mass by stimulating pancreatic beta-cell proliferation and induction of islet neogenesis. GLP-1 also promotes cell differentiation, from exocrine cells or immature islet progenitors, toward a more differentiated beta-cell phenotype, GLP-2 stimulates cell proliferation in the gastrointestinal mucosa, leading to expansion of the normal mucosal epithelium, or attenuation of intestinal injury in experimental models of intestinal disease. Both GLP-1 and GLP-2 exert antiapoptotic actions in vivo, resulting in preservation of beta-cell mass and gut epithelium, respectively. Furthermore, GLP-1 and GLP-2 promote direct resistance to apoptosis in cells expressing GLP-1 or GLP-2 receptors. Moreover, an increasing number of structurally related peptide hormones and neuropeptides exert cytoprotective effects through G protein-coupled receptor activation in diverse cell types. Hence, peptide hormones, as exemplified by GLP-1 and GLP-2, may prove to be useful adjunctive tools for enhancement of cell differentiation, tissue regeneration, and cytoprotection for the treatment of human disease(14-29). These effects are only documented well in animal systems, yet they are all potentially linked as beneficial actions of RYGB surgery, since this procedure elicits the full response of die ileal brake and causes regeneration of pancreatic beta cells by virtue of creating an absence of need for insulin treatment within 3-6 months after insulin requiring patients undergo the RYGB surgery, and before they have lost much body weight (1)
A definitive cure for type 1 diabetes is currently being pursued with enormous effort by the scientific community. Different strategies are followed to restore physiologic production of insulin in diabetic patients. Restoration of self-tolerance remains the milestone that must be reached in order to move a step further and recover a cell source capable of independent and functional insulin production. Multiple strategies aimed at modulation of both central and peripheral immunity must be considered. Promising results now show that the immune system can be modulated in a way that acquisition of a “diabetes-suppressive” phenotype is possible. Once self-tolerance is achieved, reversal of the disease may be obtained by simply allowing physiologic rescue and/or regeneration of the beta cells to take place. Given that these outcomes have already been confirmed in humans, refinement of existing protocols along with novel methods adapted to T1D reversal will allow translation into clinical trials.(30) We believe that the time is at hand to consider oral stimulation of ileal brake hormones as the method of choice for regeneration of pancreatic beta cells in patients with both T2D and T1D, using oral mimetics of RYGB surgery that produce the full range of effects.
Accumulating data from animal models of T1D and some findings from Clinical studies suggest that autoimmune destruction of islet beta cells is associated with enhanced beta cell regeneration. These authors observe that successful immune therapies, aimed at preservation of islet cell mass, result in a remarkable reduction of beta cell regeneration. Treated or not, as long as the task of treatment is limited by “making peace” with autoimmunity, the process of beta cell loss continues, so current approaches to T1D pancreas regeneration are sub-optimal. Additional therapeutic modalities capable of stimulating beta cell regeneration in the absence of active autoimmune destruction are urgently needed.(31) Brake and RYGB may become the preferred approach since they are immunomodulators but not immunosuppressive. In fact, both Brake and RYGB enhance the immune resistance overall, given their beneficial impact on viruses that evade the immune system like Hepatitis C.
The issue of beta cell regeneration in human pancreas is probably one of the most controversial aspects of T1D research. These authors review the prospects for regeneration in T1D patients, and begin their review by first describing the known mechanisms underlying beta cell development and expansion in normal human pancreatic development, as they observe that it is likely that such mechanisms might also play a role in beta cell regeneration. The sensu strictiori definition of beta cells implies replacement of lost beta cell mass by new beta cells. In their discussion, however, they use the term in a more general way, defining as regeneration the formation of new beta cells, whether or not a loss of beta cells has actually occurred. The potential mechanisms of beta cell regeneration in the human pancreas were discussed in the second part of the review. In particular, they analyzed the processes of beta cell regeneration through proliferation of beta cells, neogenesis from non-beta cell precursors, and trans-differentiation from alpha cells. In the third part of this review, they explore the arguments for and against the ability of the human pancreas to regenerate functional beta cells in the context of T1D and in other pathological conditions.(32) This review establishes the rationale for oral mimetics of ileal brake hormones as a means of regenerating pancreatic beta cells, and supports our clinical observations that this process occurs in patients with diabetes.
T1D patients rely on cumbersome chronic injections of insulin, making the development of alternate durable treatments a priority. The ability of the pancreas to generate new beta-cells has been described in experimental diabetes models and, importantly, in infants with T1D. In this review, the authors discuss recent advances in identifying the origin of new beta-cells after pancreatic injury, with and without inflammation, revealing a surprising degree of cell plasticity in the mature pancreas. In particular, the inducible selective near-total destruction of beta-cells in healthy adult mice uncovers the intrinsic capacity of differentiated pancreatic cells to spontaneously reprogram to produce insulin. This opens new therapeutic possibilities because it implies that beta-cells can differentiate endogenously, in depleted adults, from heterologous origins.(33). Some of the stimuli capable of stimulating beta cell differentiation are ileal brake hormones, supporting the use of RYGB or oral Brake™ for this purpose
The mechanisms that regulate pancreatic beta cell mass are poorly understood. While autoimmune and pharmacological destruction of insulin-producing beta cells is often irreversible, adult beta cell mass does fluctuate in response to physiological cues including pregnancy and insulin resistance. This plasticity points to the possibility of harnessing the regenerative capacity of the beta cell to treat diabetes. These authors developed a transgenic mouse model to study the dynamics of beta cell regeneration from a diabetic state. Following doxycycline administration, transgenic mice expressed diphtheria toxin in beta cells, resulting in apoptosis of 70%-80% of beta cells, destruction of islet architecture, and diabetes. Withdrawal of doxycycline resulted in a spontaneous normalization of blood glucose levels and islet architecture and a significant regeneration of beta cell mass with no apparent toxicity of transient hyperglycemia. Lineage tracing analysis indicated that enhanced proliferation of surviving beta cells played the major role in regeneration. Surprisingly, treatment with Sirolimus and Tacrolimus, immunosuppressants used in the Edmonton protocol for human islet transplantation, inhibited beta cell regeneration and prevented the normalization of glucose homeostasis. These results suggest that regenerative therapy for T1D may be achieved if autoimmunity is halted using regeneration-compatible drugs(34). RYGB and oral Brake treatment appeals to act in this manner, as were shown in the 18 patients presented here as evidence of beneficial actions on diabetes and pre-diabetes. Recent studies have revealed a surprising plasticity of pancreatic beta-cell mass. Beta-cell mass is now recognized to increase and decrease in response to physiological demand, for example during pregnancy and in insulin-resistant states. The authors and others have shown that mice recover spontaneously from diabetes induced by killing of 70-80% of beta-cells, by beta-cell regeneration. The major cellular source for new beta-cells following specific ablation, as well as during normal homeostatic maintenance of adult beta-cells, is proliferation of differentiated beta-cells. More recently, it was shown that one form of severe pancreatic injury, ligation of the main pancreatic duct, activates a population of embryonic-type endocrine progenitor cells, which can differentiate into new beta-cells. The molecular triggers for enhanced beta-cell proliferation during recovery front diabetes and for activation of embryonic-type endocrine progenitors remain unknown and represent key challenges for future research. Taken together, recent data suggest that regenerative therapy for diabetes may be a realistic goal(35). This work points to the need for oral treatments that could regenerate cells in the pancreas, and establishes why an oral mimetic of RYGB could be beneficial.
Several studies have shown that the adult pancreas possesses a potential for beta-cell regeneration upon tissue injury. One of the difficulties in studying beta-cell regeneration has been the lack of a robust, synchronized animal model system that would allow controlled regulation of beta-cell loss and subsequent proliferation in adult pancreas. The investigators present a transgenic mouse regeneration model in which the c-Myc transcription factor/mutant estrogen receptor (cMycER(TAM)) fusion protein can be specifically activated in mature beta-cells. We have studied these transgenic mice by immunohistochemical and biochemical methods to assess the ablation and posterior regeneration of beta-cells. Activation of the cMycER(TAM) fusion protein results in synchronous and selective beta-cell apoptosis followed by the onset of acute diabetes, Inactivation of c-Myc leads to gradual regeneration of insulin-expressing cells and reversal of diabetes. These results demonstrate that the mature pancreas has the ability to fully recover from almost complete ablation of all existing beta-cells. These results also suggest the regeneration of beta-cells is mediated by replication of beta-cells rather than neogenesis from pancreatic duets.(36) Combination therapy with a dipeptidyl peptidase-4 inhibitor (DPP-IV) and a proton pump inhibitor (PPI) raises endogenous levels of GLP-1 and gastrin, respectively, and restores pancreatic beta-cell mass and normoglycemia in nonobese diabetic (NOD) mice with autoimmune diabetes(37). The aim of this study was to determine whether a DPP-IV and PPI combination could increase beta-cell mass in the adult human pancreas. Pancreatic cells from adult human pancreas donors were implanted in NOD-severe combined immunodeficient (NOD-scid) mice and the mice were treated with a DPP-IV and a PPI for 16 weeks. Human grafts were examined for insulin content and insulin-stained cells. Graft beta-cell function was assessed by intravenous glucose tolerance tests (IVGTT) and by; glucose control in human cell-engrafted mice treated with streptozotocin (STZ) to delete mouse pancreatic beta-cells. Plasma GLP-1 and gastrin levels were raised to two- to threefold in DPP-IV and PPI-treated mice. Insulin content and insulin-stained cells in human pancreatic cell grafts were increased 9- to 13-fold in DPP-IV and PPI-treated mice and insulin-stained cells were co-localized with pancreatic exocrine duct cells. Plasma human G-peptide responses to IVGTT were significantly higher and STZ-induced hyperglycemia was move completely prevented in DPP-TV and PPI-treated mice with grafts than in vehicle-treated mice with grafts. In conclusion, DPP-IV and PPI combination therapy raises endogenous levels of GLP-1 and gastrin and greatly expands the functional beta-cell mass in adult human pancreatic cells implanted in immunodeficient mice, largely from pancreatic duct cells. This suggests that a DPP-IV and PPI combination treatment may provide a pharmacologic therapy to correct the beta-cell deficit in type 1 diabetes(37). As this combination of oral drugs is producing similar effects on pancreatic regeneration as RYGB or oral Brake™, and is being used in a clinical trial to treat T1D patients, the existence of this study adds validation to the use of ileal brake hormone regulators in the treatment of T1D patients who would clearly and dramatically benefit from regeneration of beta cell mass.
Aphoeline is a composition which is used in the present application and comprises dextrose and a number of other components (Aphoeline/Aphoeline II/Brake™) as described above and in U.S. patent application Ser. No. 12/932,633, filed March 2011, which incorporated by reference in its entirety herein.
While even our earliest short term studies in patients demonstrated a rapid decline in insulin resistance, it was hot initially clear whether these observed acute regulatory mechanism of suppressing insulin resistance is maintained long-term. Durable response on pancreatic insulin producing capability was desirable for long term control of T2D, and the data incorporated hemin show that is occurring in both RYGB patients and Oral Brake™ patients. Thus both have impact by creating beneficial tissue remodeling patterns in visceral organs and tissues, and of course the primary advantage of Brake™ over RYGB is that it produces the same biomarker effects as the surgery, without need for the surgery except hr cases of extreme obesity where more weight must be lost for the health of the patient. To answer these remaining questions, we investigate in this study the effect of long term stimulation of ileal hormones with Aphoeline 2, an early formulation of Brake™, on a number of metabolic problems including fatty liver, triglyceride, weight, HBA1c, and insulin levels.
Methods: Eighteen patients who participated and agreed to share their findings anonymously for publication purposes, were followed in our practice for different diseases. Nine were female and 0.9 were male, ranging in age front 26 to 71, with an average age of 55, The ethnic breakdown included one African-American, one Asian, one from the Philippines and 2 Hispanics, the rest were Caucasians. Eleven patients were pre or early diabetic with elevated pro-insulin or insulin levels or HBA1c less or equal to 7.5, but not yet taking diabetes medications. Nine were diagnosed with fatty liver and abnormal liver enzymes ALT, AST. At least 2 diagnosed with liver biopsies, 7 of these also belonged to the pre diabetic/diabetic group, consistent with the reported comorbidity of both diseases; an additional 3 had hepatitis C but were not currently taking anti-viral drugs, of these, 2 had biopsy proven cirrhosis. All patients took Aphoeline Brake™ daily orally. Aphoeline tablets contain simple carbohydrates and herbs coated with a special pH-time dependent delivery system that delivers the content of the tablet primarily to the ileum. Daily dosing consisted of a dose of 7 pills taken once a day at the same time 4 hours before the major meal. This dose delivers to the ileum a carbohydrate content equivalent to 10.5 grams of glucose. All 18 patients were encouraged to exercise and follow a healthy diet. Patients were followed monthly for periods ranging between 4 months to 16 months, with a fatty liver profile, consisting of blood level of: glucose, insulin, proinsulin, c peptide, albumin, total protein, BUN, creatinine, alpha-fetoprotein, triglyceride, cholesterol, liver enzymes, bilirubin and LDH as well as thyroid profile. Body weight and BMI were also recorded during the each visit. The metabolic profile, liver and (insulin resistance) IR 2 changes, as well as the alpha-fetoprotein, (given the presence of liver disorder in the patients studied) were recorded during the period reported.
The two-sample paired t-test7 was used to determine if (i) there was a significant decrease in the mean profiles (fatty liver, weight, triglyceride and diabetes); this was done in two ways:
(a) using data for all 18 patients, and (b) for patients with initial reading out of normal range, and
(ii) If the percent decrease was significant, for patients with initial reading out of normal range.
In addition, we also computed (iii) the 95% confidence intervals for the parameter p, the true proportion of patients for which out of range reading became normal during the period of taking the medication. This was done using the confidence interval formula for the binomial proportion7
Since the amount of decrease towards normal was proportional to the abnormal initial values we divided the patient in 2 categories one with abnormal initial values the other one with a normal starting values on the parameters of SGOT, SGPT, insulin, proinsulin, triglyceride and cholesterol, and compare initial to final values, (iii)
The results from the paired t-tests show that, at the error rate of 5% or the confidence level of 95%, patients on Aphoeline experienced a significant decrease was observed in the mean profiles of:
In this section, we present the results obtained for percent decrease in SCOT, SGPT, INSULIN, PROINSULIN, CHOLESTEROL, and, TRIGLYCRIDE The percent decrease was, calculated using the following formula:
Percent Decrease=100×(Final reading−Initial Reading)/Initial Reading
The results from the paired t-tests using the data for-patients with initial reading out of normal range show that, at the error rate of 5% or the confidence level of 95%, patients on Aphoeline experienced a statistically significant decrease in (see Table 2):
(iii) Confidence Intervals for Proportion of Patients Who Show Improvement
We also plotted these measurements vs; TIME, measured as the number of days the medication was taken orally (see
iii) Confidence Intervals for Proportion of Patients Who Show Improvement
We also computed the 95% confidence intervals for the parameter p, the true proportion of patients for which out of range reading became normal during the period of taking the medication. These calculations showed that (see Table 2):
We also plotted these measurements vs. time, measured as the number of days the medication was taken orally (see FIGS. 1EX6-16EX6). The monotonically decreasing behavior of WEIGHT and BMI with TIME can be seen from FIGS. 1EX6-2EX6.
(iii) Comparison of Subgroups with Initially Elevated Vs. Initially Normal Starting Values:
The two categories one with abnormal initial values the other one with normal shirting values on the parameters of SCOT, SGPT, insulin, proinsulin, triglyceride and cholesterol, and compare initial averages to final averages. The results are dramatic, showing that the average changes in all patients went back to normal ranges, and that effectively the patients brought ail parameters to normal range. It also showed the more dramatic response proportional to the initial value deviation from normal.
Normal ranges for the values are as follow:
For the group with the average elevated initial baseline levels,
the average abnormal initial values were as follow:
The final averages values for the same group were as follow:
The percentage decrease from initial to final for the same group was as follow:
In terms of HOMA 2 the average decrease in insulin resistance was 2.1-23, making it a decrease of 43.6% in insulin resistance.
Graph that represents the initial, final of each group as well as the normal range value is included.15
RYGB (N=T5) Comparison with Brake (N=18) from the Perspective of Change in HOMA-IR Vs. Changes in Biomarkers and Manifestations of Metabolic Syndrome.
We used available data from the literature and our own analysis of patient data for normals, obese, obese T2D, obese T2D given DPP-IV inhibitors, Byetta 10 mcg, post RYGB, and post single dose of Brake to compare the relative potency of GLP-1 after challenge. The purposes were to examine the apparently sleeping ileal brake pathway, in T2D and the obese, which was shown, and to compare the relative increase in GLP-1 from the interventions performed. The illustrated analysis is below as FIG. 1EX7.
It was clear that there was an important homology between the use of oral formulations of Brake and RYGB surgery, and in fact the questions could be precisely examined as relative potency if we used our data on biomarkers of the response of the various metabolic syndrome manifestations such as insulin resistance, liver enzymes, triglycerides, and body weight itself.
Thus a comparison of RYGB patients (N=15) and Aphoeline/Brake treated patients (N=18) was made from the two studies presented in the body of this application.
All available patients were used in these comparisons unless they did not have a value. In some analyses, only patients with abnormal values at baseline were considered. Data were taken from the studies of patients performed by the investigators. Patient demographics are described earlier.
The purpose of this combined analysis was to define common mechanisms of action between RYGB surgery and oral use of Brake, with a reliance on biomarkers for the definition of relative potency between Brake and RYGB, Data were plotted vs. HOMA-IR change, because this parameter is the first to change and show's an overall dramatic and unexpected response to both RYGB and Brake administration.
Shown below (FIGS. 2EX7 A-E) are the combined data from RYGB patients and Broke treated patients, with the before values compared to 6 months post start of the monitoring period. Each group of patients is displayed with different symbols so that the similarities and differences can be appreciated. Parameters compared between the populations and presented include HOMA-IR changes, Weight changes, HBA1c changes, AST changes, ALT changes and Triglyceride changes. Many other biomarkers were measured in both studies but it is believed that the chosen biomarkers tell the metabolic syndrome story in sufficient detail to illustrate the discovery of ileal brake mimicry between the formulation of Aphoeline/Brake and RYGB surgery.
Overall, these results show that Brake, and RYGB are acting in nearly identical fashion on the chosen biomarkers, albeit with a shift in relative potency. The statistical analysis allows that potency comparison to be made, and the outcomes are in Table 1EX7 below.
The results of this study show that chronic daily stimulation of the ileal hormones with Aphoeline/Brake™, delivered directly into the ileum, tends to stabilize and maintain the body homeostasis, as well as decrease in the fasting state the abnormal levels of insulin, glucose, triglycerides and all of the measured liver enzymes. Also the significant decrease in alpha-fetoprotein seems to indicate a decrease in inflammation of the liver. Even though we expect some decrease in triglyceride levels with decreasing insulin resistance; it seems that it does decrease to a large extent independently. Combining the decrease in insulin resistance, triglyceride and liver inflammation with decrease in liver enzymes indicates a significant improvement in liver health and signals a role for these hormones to play in regeneration of hepatocytes and maintaining liver health. Even though one can argue that the improvement in insulin resistance per se can induce all the other changes, it is to note that these hormones even though short lived exert their action by combining with receptors at the levels of the organ including the liver. Given the recent finding of an increase role of the miRNA in liver cells to decrease insulin resistance there is a possibility that: these hormones might exert (here effect: through miRNA induction. Another possibility is the relative increase of IGF-1 and 2 that is observed as well during such stimulation, and their well-known effect on decreasing insulin resistance by activating their own cellular receptor's.
The results of these studies, alone and combined, show that chronic daily stimulation of the ileal hormones with Aphoeline delivered directly into the ileum, tends to stabilize and maintain the body homeostasis, as well as decrease the abnormal levels of insulin, glucose, triglyceride and liver enzymes. These are all beneficial effects on the common manifestations of metabolic syndrome in the western world, and it was very surprising to have similar activity produced by both RYGB surgery and the oral formulation. The only significant difference was in the amount of weight lost, and we account for the greater weight loss of RYGB surgery as an effect of shrinking the size of the stomach, a clearly additive effect with the actions on the ileal brake that is absent from the patients given the oral formulation alone.
The decline in liver enzymes was remarkable and similar between the two study populations, in this case Brake performing better than the RYGB surgery, ft should be pointed out that some of the patients given Brake had hepatic abnormalities, while the RYGB patients did not. However, in both cases, the conclusion is that there is an insulin resistance associated increase in fatty liver disease occurring with obesity and T2D, and in both cases the decline in fatty liver condition was associated with RYGB surgery or the oral formulation used for treatment in both cases the decline in liver enzymes to normal occurred in the first month after starting treatment or performing surgery. Also the significant decrease in alpha-fetoprotein seems to indicate a decrease in inflammation of the liver. Even though-we expect some decrease in triglyceride levels with decreasing insulin resistance; it seems that it does decrease to a large extent earlier and independently. Combining the decrease in insulin resistance, triglyceride and liver inflammation with decrease in liver enzymes indicates a significant improvement in liver health and signals an important role for the intra portal release of these ileal brake hormones resulting from RYGB surgery or use of Brake in maintaining liver health.
One might argue that the newly discovered and remarkable improvement in insulin resistance per se can induce all the other changes. However, it is notable that these hormones, even though short lived, exert their action by combining with receptors at the levels of the organ including the liver. Given the recent finding of an increased role of the miRNA in liver cells8 to decrease insulin resistance there is a possibility that these hormones might exert there effect through miRNA induction. Another possibility is the relative increase of IGF-1 and IGF-2 that is observed as well during such stimulation, and their well-known effect on decreasing insulin resistance by activating their own cellular receptors6.
The decrease in weight was significant, but slow, and lags behind the laboratory parameters of metabolic syndrome. This indicates that weight loss is the net result of an improving system health, resolving inflammation and metabolic syndrome manifestations and a beneficial consequence of reactivated signaling originating in the ileum, rather than art independent or a leading factor preceding the other parameters. To note that metabolic parameters do not all move in a very strict linear fashion, reflecting real life variation in both individuals, real living, life style and measurements and suggesting any short-term measurements in those analyses, especially the weight loss, will not likely reflect the long term trend in these studies. Until these pathways are completely understood, it will be necessary and sufficient to use biomarkers to define relative potency and to differentiate between means of activating the ileal brake in health and disease.
Ileal brake hormones play a key role in regulating insulin secretion and glucose homeostasis, as well as reducing food intake and body weight2,4,11,12. We have previously shown6 that a single dose of Aphoeline/Brake significantly decreases glucose, c-peptide and insulin levels up to 10 hours vs, baseline in healthy volunteers. A statistically significant increase in plasma levels of PYY, GLP-1, and GLP-2 was also observed from 0 to peak hours white leptin was not significantly increased. The subjects with baseline elevated insulin and or fasting glucose experienced a much more dramatic decrease in both blood insulin and glucose levels with ileal hormone stimulation. This suggests that in normal metabolism, the balance between absorption and signaling of appetite and maintenance of the body weight is in equilibrium (
As a result of ileal brake signaling hormones, the end of the increased appetite will come more abruptly towards the end of the meal making the progression of the signal intensity non-linear. The more food that is rapidly ingested the more will be left for the distal segments and the strength of the appetite suppression signal will disproportionately increase. The absence or decrease of the signal in the jejunum associated with absorption as per obese and metabolic syndrome will mislead the measurement and the automatic maintenance that happen normally with absorption. Thus, in the obese and particularly in the obese type 2 diabetic, the ileal brake becomes less responsive, requiring increasingly more food to decrease the appetite for food. It might be thought that the ileal brake goes to sleep in increasing obesity, allowing weight gain in major proportions, all a consequence of a failure to suppress appetite. Because of the defect it will allow insulin and glucose to go higher, eventually triggering pancreatic exhaustion; This defect will be proportional to the lack of signaling, i.e. the less the signaling the more severe the insulin resistance and glucose levels, the more fatty liver and increase in triglycerides, the less body maintenance, the more possible intestinal leaks and depression of the immune system, fatty liver, reflux and less usage of fat reserves, less signaling of satiety. In short, all of the metabolic syndrome manifestations as detailed here develop in a step by step fashion as there is a decline in the hormonal signals from the L cells. Obesity and type 2 diabetes develop step by step all based on an initial relative or absolute lack of signaling from L cells at the level of the jejunum or ileum. It is apparent that patients with obesity and type 2 diabetes have very low amounts of ileal brake hormone release, as shown in FIG. 1EX7 above. As the L-cells are not abnormal, just asleep at this point, it was shown in our data that either RYGB surgery or oral administration of Aphoeline/Brake can restore the downtrend in output of the stimulating hormones, from the ileum, restore the suppression of appetite, and indeed, to create an overall wakeup of the ileal brake. In our data, it was demonstrated that the L-cells distally can substitute for the proximal signaling as well. They did indeed decrease both insulin levels as well as blood glucose acutely, especially in people with elevated baseline levels, showing that the stimulation of the more distal L-cells have the potential to reverse the defect in metabolic syndrome. What was left to prove at that point was that long term stimulation will maintain the same benefit and continue to reverse the defect of signaling and the beneficial effect can be maintained long term.
In this pilot study of patients given Aphoeline/Brake compared with RYGB surgery, results suggest that, long-term stimulation of the ileal hormones with either of these interventions can wake up the otherwise normal but sleeping ileal brake, and thereby suppress insulin resistance as well as lower blood glucose, the decrease being more pronounced in patients with a higher baseline levels. Brake treated patients had similar profiles of biomediators as patients with RYGB surgery, showing the homology between these approaches to ileal brake management of metabolic syndrome manifestations for the first time. Also the expected increase of insulin as reported with GLP.1 analogs, when injected peripherally did not happen, with the oral ileal stimulation, indicating the ileal hormones increase in the portal system independent of absorption and stimulation, at the level of the jejunum, under physiological conditions, is likely to inhibit insulin resistance by lowering both insulin and blood glucose simultaneously5.
In addition to the multitude of effects that ileal hormones exert on different organs3,9 in healthy individuals, they also seem to enhance absorption and control of blood glucose and work in tandem with G1P, and other hormones (that stimulate insulin with meals, and enhance absorption) to decrease insulin resistance and move the glucose intracellularly. This prevents longer period of hyperinsulinemia, hyperglycemia, with subsequent hypoglycemia and beta cell exhaustion. All of these processes are involved and associated with conditions such as pre-diabetes, type II diabetes9, metabolic syndrome, and obesity10,11 all of these abnormalities are corrected in a similar manner, insulin resistance first, by RYGB or an oral treatment with Aphoeline/Brake.
This study also demonstrates that the short term effects and benefits observed with oral stimulation of the ileal hormones are sustained with long term stimulation resulting in similar benefits to RYGB. The benefits were not identical with respect to magnitude of weight loss, but oral use of Brake does not alter the size of the stomach so there is greater weight loss overall with RYGB surgery. This may suggest the pathology of abnormal signaling lies in the jejunum where early signaling is admixed with absorption. Permanent or temporary changes could have happened either to alter the stimulation secretion and/or action of the hormones or the production and/or differentiation of the cells from a stem cell in the crypt. Another possibility is that the long term deficiencies in those hormones might alter the post receptor signaling in the organ as per miRNA which will interfere with insulin resistance and glucose homeostasis. Therefore in this scenario it is possible to start with a somatic problem of food imbalance or bad food interfering with hormone release and signaling to trigger a permanent damage that will interfere with miRNA that in turn will make the changes from a pro-syndrome to a full blown irreversible disease. In this scenario prevention and early detection and intervention is the best and cheapest approach to the problem, and seems to agree with real life reality.
Because of the primordial importance of the L cells signaling in the ileum, a survival feature to prevent malabsorption and death, the L cells presence there is denser and more uniform. They form an emergency signaling or brake, present in most living creatures. This is in contrast to the more sparse heterogeneous distribution in the jejunum. The L cells in the ileum are more protected and the signaling more preserved and less easily damaged than the jejunal signaling, therefore even though the L cells jejunal signaling starts very early through food contact which happens to be the same area of absorption. The more intense signaling is the further down were normal amount of food does not get to and is absorbed before it reaches dial area. Since the main problem in obese, Type II diabetics and patients with metabolic syndrome seems to be a defect in the early response of L cells to meals, Ileal stimulation with Aphoeline/Brake acts similar to the stimulation induced with RYGB surgery,(FIG. 19) bringing food down to the functioning L-cells signaling in the ileum. By bypassing the” dead zone signaling segment it helps reset the signaling process and allowing foe body to receive the signaling and maintenance required associated with absorption in the case of bypass and without absorption in the case of Aphoeline/Brake.
Beside the improvement in function, the ileal signaling brings about the true signaling that allows the brain to gage the status of the body as well as to determine and use the caloric reserve present. The GLP1 and PYY were shown to act on the hypothalamus with blood glucose to signal satiety12. Without the ileal hormones there is no automatic sensor reading of the caloric status of the body available, and the brain has to rely on the conscious logical part to calculate the calories (like in conscious calorie count) and has to work contrary to what the faulty biological signal that is being sent to the brain, (not enough calories), making it very difficult for obese, diabetics and others to live their lives accordingly. Steady weight gain is the result of this down-regulation of the ileal brake signaling. The ileal hormones will also improve the intestine itself as recently demonstrated with GLP-2,15 as well as allow the body to use its reserve of fat as recently published with oxyntomodulin16.
The theoretical question whether prolonged treatment i.e. oral ileal stimulation, could reverse the original pathology in the Intestine, as well as to allow the body to restore normal signaling again. This will have to wait further testing. However, it is clear that RYGB surgery has that beneficial tong term effect, and if one compares our findings of RYGB patients with those given Aphoeline/Brake, the summary of results are found in table XX below.
In general, the results in Table 1EX7 show Brake to be at least 20% as active on the ileal brake over long term (6 months) as RYGB surgery. With respect to some key parameters like HOMA-IR, a measure of insulin resistance. Brake is as much as 62% as active as RYGB. Concerning the decline in HBA1c, a measure of long term glucose exposure, Brake is 54% as potent as RYGB surgery. Each of these findings shows similar slopes of response biomarkers between RYGB and Brake. This further indicates that the ileal brake is re-activated to the benefit of decreases in the associated metabolic syndrome biomarkers and adverse event pathways. Thus, both RYGB and Brake are capable of waking up the ileal brake on a long term basis, and both therefore act in a similar manner in the amelioration of metabolic syndrome and its complications. This is very novel and important, because long term studies have shown that RYGB surgery can reverse atherosclerosis and type 2 diabetes, and thus there is the potential for an oral medication to accomplish these same goals in the treatment of patients with metabolic syndromes. As to the relative potency of Brake vs. RYGB, the importance of these ratios will become clearer as the biomarkers linkage to both short and long term outcomes are studied.
Because the true signaling derived from the ileal hormones to the brain is triggered with fat and carbohydrate (that usually gives satisfaction as well as energy and signaling the body has enough energy to spend), it is not surprising that these two types of food are associated with fatigue, tiredness as well as with depression, it also explain the good taste associated with them. Is this the answer to food addiction13, the brain and the body looking for the right signaling?
We are predicting that a combination of oral stimulation and oral medication or injection or a combination should be added to the prospective clinical studies. Further consideration of using oral ileal stimulation in combination with other medications, similar to die one with Hepatitis C, and other viruses, combination treatments could be rationally designed, especially for diabetic treatment where brake would be given with DPP-IV inhibitors. Other drugs could be contribute to augmented response, inducing response or effectiveness. In altered metabolism the balance will shift toward the absorption, insulin production and poor or no stimulation of the ileal hormones, therefore poor signaling of satiety and body caloric reserve and usage, resulting in insulin resistance, fatty liver and obesity, instead of a smooth transition of food and signaling and coordinated secretion. (FIG. 2EX8). Both gastric bypass as well as oval ileal stimulation with Aphoeline will restore some physiological signaling.
Like in the acute stimulation of the ileal hormones by Aphoeline-II, the chronic daily stimulation of the ileal hormones showed again that these hormones in their natural physiological release in the portal system, tend to stabilize and maintain the body homeostasis, by decreasing in the fasting state the abnormal levels of insulin, glucose triglyceride, and by decreasing the liver enzymes directly or indirectly. Of note, even the alpha-fetoprotein seems to decrease significantly confirming a decrease in inflammation of the liver by a mechanism that does not involve immunosuppression. The decrease in triglyceride seems to be significant and may reflect an optimization of lipid handling by both the G1 tract and the liver. Even though we expect some decrease in triglyceride levels with decreasing insulin resistance, it seems that the triglyceride impact is earlier and independent of the impact on weight, and it was extremely novel to observe these long term benefits from an oral mimetic of RYGB surgery.
The decrease in weight was significant but slow and follows the other-parameters, indicating the weight loss is a result of an improving system and signaling, rather than what is often stated. Weight reduction in fact may be an independent factor or a leading one that follows the other parameters driven by the ileal brake hormone regulating pathways. To note that metabolic parameters do not all move in a very strict linear fashion, reflecting real life variation in both individuals and measurements and suggesting any short-term measurements in those analyses, especially the weight loss, will not likely reflect the long term trend of organ and tissue regeneration that was the novel finding of these studies.
Non-alcoholic fatty liver, disease (NAFLD) is the hepatic manifestation of metabolic syndrome and the leading cause of chronic liver disease in the Western world. Twenty percent of NAFLD individuals develop chronic hepatic inflammation (non-alcoholic steatohepatitis, NASH) associated with cirrhosis, portal hypertension and hepatocellular carcinoma, yet the causes of progression from NAFLD to NASH remain obscure. In recent publications, the authors show that the NLRP6 and NLRP3 inflammasomes and the effector protein IL-18 negatively regulate NAFLD/NASH progression, as well as multiple aspects of metabolic syndrome via modulation of the gut microbiota. Different mouse models reveal that inflammasome-deficiency-associated changes in the configuration of the gut microbiota are associated with exacerbated hepatic steatosis and inflammation through influx of TLR4 and TLR9 agonists into the portal circulation, leading to enhanced hepatic tumour-necrosis factor (TNF)-alpha expression that drives NASH progression. Furthermore, co-housing of inflammasome-deficient mice with wild-type mice results in exacerbation of hepatic steatosis and obesity. Thus, altered Interactions between the gut microbiota and the host, produced by defective NLRP3 and NLRP6 inflammasome sensing, may govern the rate of progression of multiple metabolic syndrome-associated abnormalities, highlighting the central role of the microbiota in the pathogenesis of heretofore seemingly unrelated systemic auto-inflammatory and metabolic disorders.(38-41). Of significance, our recent studies in RYGB patients(42) as well as the studies in these 18 patients, show that ileal brake hormones moderate these effects on NAFLD. Thus, the novel observation of RYGB and oral Brake is modulation of the G1 tract inflammasome process by ileal brake hormones, and the subsequent ability to use this novel treatment to decrease both hepatic inflammation and NAFLD. This is further beneficial in the treatment of hepatitis C.
With regard to the role of GLP-2 in the improvement of intestinal function and reabsorptive capability, several research groups have concluded that GLP-2 increases gut growth, reduces mucosal cell death, and augments mesenteric blood flow and nutrient absorption. Exogenous GLP-2(1-33) also stimulates glucagon secretion and enhances gut barrier function with implications for susceptibility to systemic inflammation and subsequent metabolic dysregulation, Bahrami and colleagues examined the importance of GLP-2 receptor (GLP-2R) signaling for glucose homeostasis in multiple models of metabolic stress, diabetes, and obesity. Body weight, islet function, glucose tolerance, and islet histology were studied in wild-type, high-fat fed, lean diabetic, Glp2r(−/−) and ob/ob:Glp2r(−/−) mice. They found that GLP-2 did not stimulate glucagon secretion from isolated pancreatic islets in vitro, and exogenous GLP-2 had no effect on the glucagon response to insulin-induced hypoglycemia in vivo. Glp2r(−/−) mice exhibit no change in glycemia, and plasma glucagon levels were similar in Glp2r(−/−) and Glp2r(+/+) mice after hypoglycemia or after oral or intraperitoneal glucose challenge. Moreover, glucose homeostasis was comparable in Glp2r(−/−) and Glp2r(+/+) mice fed a high-fat diet for 5 months or after induction of streptozotocin-induced diabetes. In contrast, loss of the GLP-2R leads to increased glucagon secretion and alpha-cell mass, impaired intraperitoneal glucose tolerance and hyperglycemia, reduced hem-cell mass, and decreased islet proliferation in ob/ob:Glp2r(−/−) mice. CONCLUSIONS: Our results show that, although the GLP-2R is not critical for the stimulation or suppression of glucagon secretion or glucose homeostasis in normal or lean diabetic mice, elimination of GLP-2R signaling in obese mice impairs the normal islet adaptive response required to maintain glucose homeostasis(43). Clearly, GLP-2 does not act alone even though it is beneficial to cellular regeneration. This points to the novel importance of stimulating the Is-cells to produce the ileal brake regulatory hormones as opposed to the current strategy to purity each one and administer it by injection. The full response is necessary, as are all die ileal brake hormones as released by either oral Brake or RYGB surgery.
The actions of the structurally related proglucagon-derived peptides (PGDPs)-glucagon, glucagon-like peptide (GLP)-1 and GLP-2-are focused on complementary aspects of energy homeostasis. Glucagon opposes insulin action, regulates hepatic glucose production, and is a primary hormonal defense against hypoglycemia. Conversely, attenuation of glucagon action markedly improves experimental diabetes, hence glucagon antagonists may prove useful for the treatment of type 2 diabetes. GLP-1 controls blood glucose through regulation of glucose-dependent insulin secretion, inhibition of glucagon secretion and gastric emptying, and reduction of food intake. GLP-1-receptor activation also augments insulin biosynthesis, restores beta-cell sensitivity to glucose, increases beta-cell proliferation, and reduces apoptosis, leading to expansion of the beta-cell mass. Administration of GLP-1 is highly effective in reducing blood glucose in subjects with type 2 diabetes but native GLP-1 rapidly degraded by dipeptidyl peptidase IV. A GLP-1-receptor agonist, exendin 4, has recently been approved for the treatment of type 2 diabetes in the US. Dipeptidyl-peptidase-IV inhibitors, currently in phase III clinical trials, stabilize the postprandial levels of GLP-1 and gastric inhibitory polypeptide and lower blood glucose in diabetic patients via inhibition of glucagon secretion and enhancement of glucose-stimulated insulin secretion. GLP-2 acts proximally to control energy intake by enhancing nutrient absorption and attenuating mucosal injury and is currently in phase III clinical trials for the treatment of short bowel syndrome. Thus the modulation of proglucagon-derived peptides has therapeutic potential for the treatment of diabetes and intestinal disease(44).
Gut peptides exert diverse effects regulating satiety, gastrointestinal motility and acid secretion, epithelial integrity, and both nutrient absorption and disposal. These actions are initiated by activation of specific G protein-coupled receptors and may be mediated by direct or indirect effects on target cells. More recent evidence demonstrates that gut peptides, exemplified by glucagon-like peptides-1 and 2 (GLP-1 and GLP-2), directly regulate signaling pathways coupled to cell proliferation and apoptosis. GLP-1 receptor activation enhances beta-cell proliferation and promotes islet neogenesis via activation of pdx-1 expression. The proliferative effects of GLP-1 appear to involve multiple intracellular pathways, including stimulation of Akt, activation of protein kinase Czeta, and transactivation of the epidermal growth factor receptor through the c-src kinase. GLP-1 receptor activation also promotes cell survival in beta-cells and neurons via increased levels of cAMP leading to cAMP response element binding protein activation, enhanced insulin receptor substrate-2 activity and, ultimately, activation of Akt. These actions of GLP-1 are reflected by expansion of beta-cell mass and enhanced resistance to beta-cell injury in experimental models of diabetes in vivo. GLP-2 also promotes intestinal cell proliferation and confers resistance to cellular injury in a variety of cell types. Administration of GLP-2 to animals with experimental intestinal injury promotes regeneration of the gastrointestinal epithelial mucosa and confers resistance to apoptosis in an indirect manner via yet-to-be identified GLP-2 receptor-dependent regulators of mucosal growth and cell survival. These proliferative and antiapoptotic actions of GLP-1 and GLP-2 may contribute to protective and regenerative actions of these peptides fit human subjects with diabetes and intestinal disorders, respectively (45).
BACKGROUND & AIMS: Gut-derived peptides including ghrelin, cholecystokinin (CCK), peptide YY (PYY), glucagon-like peptide (GLP-1), and GLP-2 exert overlapping actions on energy homeostasis through defined G-protein-coupled receptors (GPCRs). The proglucagon-derived peptide (PGDP) oxyntomodulin (OXM) is cosecreted with GLP-1 and inhibits feeding in rodents and humans; however, a distinct receptor for OXM has not been identified.
METHODS; We examined the mechanisms mediating oxyntomodulin action using stable cell lines expressing specific PGDP receptors in vitro and both wild-type and knockout mice in vivo. RESULTS: OXM activates signaling pathways in cells through glucagon or GLP-1 receptors (GLP-1R) but transiently inhibits food intake in vivo exclusively through the GLP-IR. Both OXM and the GLP-1R agonist exendin-4 (Ex-4) activated neuronal c-fos expression in the paraventricular nucleus of the hypothalamus, the area postrema, and the nucleus of the solitary tract following intraperitoneal (i.p.) injection. However, OXM transiently inhibited food intake in wild-type mice following intracerebroventricular (i.c.v.) but not i.p. administration, whereas Ex-4 produced a more potent and sustained inhibition of food intake following both i.c.v. and i.p. administration. The anorectic effects of OXM were preserved in Gcgr(−/−) mice but abolished in GLP-1R(−/−) mice. Although central Ex-4 and OXM inhibited feeding via a GLP-1R-dependent mechanism, Ex-4 but not OXM reduced VO2 and respiratory quotient in wild-type mice. Conclusions: These findings demonstrate that structurally distinct. PGDPs differentially regulate food intake and energy expenditure by interacting with a GLP-1R-dependent pathway. Hence ligand-specific activation of a common GLP-1R increases the complexity of gut-central nervous system pathways regulating energy homeostasis and metabolic expenditure (46).
There is also abundant evidence that oral RYGB mimetics could improve lipid metabolism. For example, excessive postprandial lipemia is a prevalent condition that results from intestinal oversecretion of apolipoprotein B48 (apoB48)-containing lipoproteins. GLP-2 is a gastrointestinal-derived intestinotrapic hormone that links nutrient absorption to intestinal structure and function. The effects of GLP-2 on intestinal lipid absorption and lipoprotein production were studied in hamsters, and intestinal lipid absorption and chylomicron production were quantified in hamsters, wild-type mice, and Cd36(−/−) mice infused with exogenous GLP-2. Newly synthesized apoB48 was metabolically labeled in primary hamster jejunal fragments. Fatty acid absorption was measured, and putative fatty acid transporters were assessed by immune-blotting. In these animals, human GLP-2 increased secretion of the triglyceride (TG)-rich lipoprotein (TRL)-apoB48 following oral administration of olive oil to hamsters: TRL and cholesterol mass each: increased 3-fold. Fast protein liquid chromatography profiling indicated that GLP-2 stimulated secretion of chylomicron/very low-density lipoprotein-sized particles. Moreover, GLP-2 directly stimulated apoB48 secretion in jejunal fragments cultured ex vivo, increased expression of fully glycosylated cluster of differentiation 36/fatty acid translocase (CD36), and induced intestinal absorption of [(3)H]triolein. The ability of GLP-2 to increase intestinal lipoprotein production was lost in Cd36(−/−) mice. CONCLUSIONS: GLP-2 stimulates intestinal apoB48-containing lipoprotein secretion, possibly through increased lipid uptake, via a pathway that requires CD36. These findings suggest that GLP-2 represents a nutrient-dependent signal that regulates intestinal lipid absorption and the assembly and secretion of TRLs from intestinal enterocytes (47).
The research group of Tsujimoto in Japan has been examining the GPR-120 receptor on the L-cell surface, which detects lipids in the distal ileum and activates the ileal brake in response to lipids at that site (48, 49). As free fatty acids provide an important energy source as nutrients, and act as signalling molecules in various cellular processes, several G-protein-coupled receptors have been identified as free-Tatty-acid receptors important in physiology as well as in several diseases. GPR120 (also known as O3FAR1) functions as a receptor for unsaturated long-chain free fatty acids and has a critical role in various physiological homeostasis mechanisms such as adipogenesis, regulation of appetite and food preference. They show that GPR120-deficient mice fed a high-fat diet develop obesity, glucose intolerance and fatty liver with decreased adipocyte differentiation and lipogenesis and enhanced hepatic lipogenesis. Insulin resistance in such mice is associated with reduced insulin signalling and enhanced inflammation in adipose tissue. In humans, they determined that GPR120 expression in adipose tissue is significantly higher in obese individuals than in lean controls. GPR120 exon sequencing in obese subjects reveals a deleterious non-synonymous mutation (p.R270H) that inhibits GPR120 signalling activity. Furthermore, the p.R270H variant increases the risk of obesity in European populations. Overall, this study demonstrates that the lipid sensor GPR120 has a key role in sensing dietary fat and, therefore, in the control of energy balance in both humans and rodents.(48, 49). Hie novel finding in our patients is that the luminal surface receptor is doubtless stimulated by lipid content, in oral Brake™ or in diet by RYGB diversion of lipids to the ileum.
Ileal brake hormones play a key role in regulating insulin secretion and glucose homeostasis, as well as reducing food intake and body weight (3, 5, 9). We previously have studied the effect of an ileal delivery formulation made of carbohydrates and natural herbs on die levels of these hormones and their associated biomarkers in healthy volunteers. Results show a single dose of Aphoeline-1 significantly decreased glucose, c-peptide and insulin levels up to 10 hours vs. baseline (filing 2010 and incorporated into October 2011 as well). A statistically significant increase in plasma levels of PYY, GLP1, and GLP2 was also observed from 0 to peak hours while leptin was not significantly increased. On the subjects found to have initially elevated insulin and or fasting glucose, the stimulation of the ileal hormones had a much more dramatic effect in decreasing both the insulin and the blood sugar. We postulated that in normal metabolism, the balance between absorption and signaling of satiety and maintenance of the body is in equilibrium. The balance among these factors is illustrated in FIG. 2EX8 below.
In altered metabolism the balance will shift toward the absorption, insulin production and poor or no stimulation of the ileal hormones, therefore poor signaling of satiety and body caloric reserve and usage, resulting in insulin resistance, fatty liver and obesity. Obesity is a natural state in a setting of excessive availability of readily absorbed, dense and high nutritional content foods, typical of the modern western diet. Even after obesity is fully developed it is reversible. Both RYGB and oval ileal stimulation of ileal hormones with Brake will restore some physiological signaling. This is shown in FIG. 2EX9.
From these studies in volunteers and patients, the following conclusions are drawn:
The inventors have demonstrated in the present invention that the short term oral stimulation of the ileal hormones continue to work the same in the long term chronic stimulation bringing all the benefits associated with it.
One might predict that the pathology of abnormal signaling lies in jejunum where the impact of early signaling defects is admixed with more efficient absorption. Permanent or temporary changes could have happened either to alter the, stimulation, secretion of the hormones or the production, or differentiation of the cells from a stem cell in the crypt.
Because of the primordial importance of the signaling in the ileum as a survival feature to prevent malabsorption and death, less heterogeneity more uniform L-cells (as an emergency signaling or brake, present in most living creatures) compared to the jejunum, the ileal break is more protected and less easily damaged than the jejunal signaling, and the signaling is preserved.
Therefore in our oral stimulation, we are using the ileal stimulation with an ileal brake hormone releasing substance (preferably, Brake™), a mimetic of RYGB, to reset the signaling process and allow the body to recover by regeneration of new cells and tissues. Besides the improvement in organ function, we bring about the true signaling that allows the brain to gage the status of the body as well as to determine and use the caloric reserve present. Without it there is no automatic reading of the caloric status of the body available, and one has to rely on the conscious logical part of the brain to calculate the calories and has to work contrary to what the faulty biological signal is sending to the brain, (not enough calories), making it very difficult for obese, diabetics and others to live their lives accordingly.
These hormones will improve the intestines, pancreas and liver, itself, as recently demonstrated with GLP-2 (51). They also permit the body to use its reserve of fat as recently published about oxyntomodulin(52). An interesting question is whether a prolonged treatment i.e. oral ileal stimulation, could reverse the original pathology in the intestine, as well as to allow normal signaling again. The data here suggest regeneration and restoration is possible across most of the organs and tissues of the G1 tract, pancreas, liver and blood vessels.
