Furthermore, the present invention relates to a method for marketing GLP-1 compounds and to advertising media used for disseminating information.
A specific type of polyneuropathy develops in patients that are treated within an intensive care unit (hereinafter also designated ICU) for several days to weeks and this for a variety of primary injuries or illnesses. This polyneuropathy, known as “Critical Illness Polyneuropathy” (hereinafter also designated CIPNP) occurs in about 70% of patients who have the systemic inflammatory response syndrome (SIRS) (Zochodne D W et al. 1987 Polyneuropathy associated with critical illness: a complication of sepsis and multiple organ failure. Brain, 110: 819-842); (Leijten F S S & De Weerdt A W 1994 Critical illness polyneuropathy: a review of the literature, definition and pathophysiology. Clinical Neurology and Neurosurgery, 96: 10-19). However, clinical signs are often absent and it remains an acute problem in many ICUs worldwide. Nonetheless, it is an important clinical entity as it is a frequent cause of difficulty in weaning patients from the ventilator and it leads to problems with rehabilitation after the acute illness has been treated and cured.
When CIPNP is severe enough, it causes limb weakness and reduced tendon reflexes. Sensory impairment follows but is difficult to test in ICU patients. Electrophysiological examination (EMG) is necessary to establish the diagnosis (Bolton C F. 1999 Acute Weakness. In: Oxford Textbook of Critical Care; Eds. Webb A R, Shapiro M J, Singer M, Suter P M; Oxford Medical Publications, Oxford UK; pp. 490-495). This examination will reveal a primary axonal degeneration of first motor and then sensory fibers. Phrenic nerves are often involved. Acute and chronic denervation has been confirmed in muscle biopsies of this condition. If the underlying condition (sepsis or SIRS) can be successfully treated, recovery from and/or prevention of the CIPNP can be expected. This will occur in a matter of weeks in mild cases and in months in more severe cases. In other words, the presence of CIPNP can delay the weaning and rehabilitation for weeks or months.
The pathophysiology of this type of neuropathy remains unknown (Bolton C F 1996 Sepsis and the systemic inflammatory response syndrome: neuromuscular manifestations. Crit Care Med. 24: 1408-1416). It has been speculated to be directly related to sepsis and its mediators. Indeed, cytokines released in sepsis have histamine-like properties which may increase microvascular permeability. The resulting endoneural edema could induce hypoxia, resulting in severe energy deficits and hereby primary axonal degeneration. Alternatively, it has been suggested that cytokines may have a direct cytotoxic effect on the neurons. Contributing factors to disturbed microcirculation are the use of neuromuscular blocking agents and steroids. Moreover, a role for aminoglucosides in inducing toxicity and CIPNP has been suggested. However, there is still no statistical proof for any of these mechanisms in being a true causal factor in the pathogenesis of CIPNP.
Polyneuropathy of critical illness was first described in 1985 by three different investigators, one Canadian, one American, and one French. Until recently there was no effective treatment to prevent or stop Critical Illness Polyneuropathy. Until recently the current standard of practice of care, especially of critically ill patients, was that within the settings of good clinical ICU practice, blood glucose levels are allowed to increase as high as to 250 mg/dL or there above. The reason for this permissive attitude is the thought that high levels of blood glucose are part of the adaptive stress responses, and thus do not require treatment unless extremely elevated (Mizock B A. Am J Med 1995; 98: 75-84). Also, relative hypoglycaemia during stress is thought to be potentially deleterious for the immune system and for healing (Mizock B A. Am J Med 1995; 98: 75-84).
The recent work of G. Van Den Berghe showed that mortality in an ICU could be reduced by strictly controlling the blood glucose level with insulin (WO 01/85256). Although insulin is very effective for treating hyperglycaemia and has widespread therapeutic applications developed over the past 80 years, insulin may also produce hypoglycaemic events when administered in high dosages.
Human GLP-1 is a 37 amino acid residue peptide originating from preproglucagon which is synthesised i.a. in the L-cells in the distal ileum, in the pancreas and in the brain. GLP-1 is an important gut hormone with regulatory function in glucose metabolism and gastro-intestinal secretion and metabolism. Processing of preproglucagon to give GLP-1(7-36)-amide, GLP-1(7-37) and GLP-2 occurs mainly in the L-cells. The fragments GLP-1(7-36)-amide and GLP-1(7-37) are both glucose-dependent insulinotropic agents. In the past decades a number of structural analogs of GLP-1 were isolated from the venom of the Gila monster lizards (Heloderma suspectum and Heloderma horridum). Exendin-4 is a 39 amino acid residue peptide isolated from the venom of Heloderma horridum, and this peptide shares 52% homology with GLP-1. Exendin-4 is a potent GLP-1 receptor agonist which has been shown to stimulate insulin release and ensuing lowering of the blood glucose level when injected into dogs. The group of GLP-1(1-37), exendin-4(1-39), certain fragments thereof, analogs thereof and derivatives thereof, (hereinafter designated GLP-1 compounds) are potent insulinotropic agents. Most importantly the group of GLP-1(1-37), exendin-4(1-39), insulinotropic fragments thereof, insulinotropic analogs thereof and insulinotropic derivatives thereof (hereinafter designated GLP-1 compounds)I are also glucose-dependent in their action, i.e. they normalize hyperglycemia but as blood glucose concentration decreases their activity attenuates so that the risk of hypoglycemic events are eliminated or greatly reduced as compared to the conventional treatment with insulin. This lack of severe side effect from overdosing GLP-1 compounds make them very well suited to the therapeutic application within ICU. The density of intense monitoring and multiple treatments of patients in ICU makes it highly advantageous that the strict control of the blood glucose level is simple and void of risks for hypoglycaemic events.
This invention is based on the discovery that critical illness in a patient and/or CIPNP can be prevented, treated or cured, at least to a certain extent, by controlling glucose metabolism during said critical illness by applying intensive treatment with a GLP-1 compound.
Blood glucose level is kept below an upper limit which is about 110 mg/dL, about 120 mg/dL or about 130 mg/dL. More specifically, blood glucose level is clamped within a range where the lower limit can be selected to be about 60, about 70 or about 80 mg/dL and the upper limit can be selected to be about 110, about 120 or about 130 mg/dL, more specifically to the normal range (i.e., from about 80 to about 110 mg/dL). The skilled art worker, for example, the physician, will be able to decide exactly which upper and lower limits to use. Alternatively, the range is from about 60 to about 130, preferably, from about 70 to about 120, more preferred, from about 80 to about 110 mg/dL.). The skilled art worker will be able to determine the dosage of GLP-1 compound without risking to induce a hypoglycaemic event because GLP-1 compounds have a glucose-dependent action where insulin release is attenuated at lower blood glucose concentrations.

Examples of insulinotropic fragments of exendin-4(1-39) are exendin-4(1-38) and exendin-4(1-31). The insulinotropic property of a compound may be determined by in vivo or in vitro assays well known in the art. For instance, the compound may be administered to an animal and monitoring the insulin concentration over time. Insulinotropic analogs of GLP-1(1-37) and exendin-4(1-39) refer to the respective molecules wherein one or more of the amino acids residues have been exchanged with other amino acid residues and/or from which one or more amino acid residues have been deleted and/or from which one or more amino acid residues have been added with the proviso that said analogue either is insulinotropic or is a prodrug of an insulinotropic compound. Examples of insulinotropic analogs of GLP-1(1-37) are e.g. Met8-GLP-1(7-37) wherein the alanine in position 8 has been replaced by methionine and the amino acid residues in position 1 to 6 have been deleted, and Arg34-GLP-1(7-37) wherein the valine in position 34 has been replaced with arginine and the amino acid residues in position 1 to 6 have been deleted, and a fusion protein between GLP-1(7-37) and human serum albumin.

Further examples of GLP-1(1-37), exendin-4(1-39), insulinotropic fragments thereof, insulinotropic analogs thereof and insulinotropic derivatives thereof are described in WO 98/08871, WO 99/43706, U.S. Pat. No. 5,424,286 and WO 00/09666.
The term “stable GLP-1 analog/derivative”, as used herein refers to a GLP-1(1-37) analog or derivative thereof which exhibits an in vivo plasma elimination half-life of at least 10 hours in man, as determined by the method described below. Examples of stable derivatives of GLP-1 analogs can be found in WO 98/08871, WO 99/43706 and WO 02/46227. The method for determination of plasma elimination half-life of a compound in man is : The compound is dissolved in an isotonic buffer, pH 7.4, PBS or any other suitable buffer. The dose is injected peripherally, preferably in the abdominal or upper thigh. Blood samples for determination of active compound are taken at frequent intervals, and for a sufficient duration to cover the terminal elimination part (e.g. Pre-dose, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 24 (day 2), 36 (day 2), 48 (day 3), 60 (day 3), 72 (day 4) and 84 (day 4) hours post dose). Determination of the concentration of active compound is performed as described in Wilken et al., Diabetologia 43(51):A143, 2000. Derived pharmacokinetic parameteres are calculated from the concentration-time data for each individual subject by use of non-compartmental methods, using the commercially available software WinNonlin Version 2.1 (Pharsight, Cary, N.C., USA). The terminal elimination rate constant is estimated by log-linear regression on the terminal log-linear part of the concentration-time curve, and used for calculating the elimination half-life.
The term “stable exendin-4 analog/derivative”, as used herein refers to a exendin-4(1-39) analog or derivative thereof which exhibits an in vivo plasma elimination half-life of at least 10 hours in man, as determined by the method described above.

The term “insulin analogues”, as used herein refers to insulin wherein one or more of the amino acid residues have been exchanged with another amino acid residue and/or from which one or more amino acid residue has been deleted and/or from which one or more amino acid residue has been added with the proviso that said insulin analogue has a sufficient insulin activity to lower the blood glucose level. Using results from the so-called free fat cell assay, any skilled art worker, for example, a physician, knows when and which dosages to administer of the insulin analogue. Examples of insulin analogues are described in the following patents and equivalents thereto: U.S. Pat. No. 5,618,913, EP 254,516, EP 280,534, U.S. Pat. No. 5,750,497, and U.S. Pat. No. 6,011,007. Examples of specific insulin analogues are insulin aspart (i.e., AspB28 human insulin), insulin lispro (i.e., LysB28,ProB29 human insulin), and insulin glargine (i.e., GlyA21,ArgB31,ArgB32 human insulin).
The term “derivatives of insulin”, as used herein are what a skilled art worker generally considers derivatives, for example, insulin having one or more substituents not present in the parent insulin molecule. Also included in “derivatives of insulin” are derivatives of insulin analogs. Examples of such compounds are described in the following patents and equivalents thereto: U.S. Pat. No. 5,750,497, and U.S. Pat. No. 6,011,007. An example of a derivative of insulin is insulin detemir (i.e., des-ThrB30 human insulin γ LysB29 tetradecanoyl).
The term “non-diabetic patient”, as used herein refers to a patient who has not been diagnosed as having diabetes.
In its broadest sense, the term a “critically ill patient” (herein designated CIP), as used herein refers to a patient who has sustained or are at risk of sustaining acutely life-threatening single or multiple organ system failure due to disease or injury, a patient who is being operated and where complications supervene, and a patient who has been operated in a vital organ within the last week or has been subject to major surgery within the last week. In a more restricted sense, the term a “critically ill patient”, as used herein refers to a patient who has sustained or are at risk of sustaining acutely life-threatening single or multiple organ system failure due to disease or injury, or a patient who is being operated and where complications supervene. In an even more restricted sense, the term a “critically ill patient”, as used herein refers to a patient who has sustained or are at risk of sustaining acutely life-threatening single or multiple organ system failure due to disease or injury. Similarly, these definitions apply to similar expressions such as “critical illness in a patient” and a “patient is critically ill”.
The term “Intensive Care Unit” (herein designated ICU), as used herein refers to the part of a hospital where critically ill patients are treated. Of course, this might vary from country to country and even from hospital to hospital and said part of the hospital may not necessary, officially, bear the name “Intensive Care Unit” or a translation or derivation thereof. Of course, the term “Intensive Care Unit” also covers a nursing home, a clinic, for example, a private clinic, or the like if the same or similar activities are performed there.
The term “Criticall illness polyneuropathy” (herein designated CIPNP), as used herein refers to the specific type of polyneuropathy that develops in patients treated within an ICU for several days to weeks and this for a variety of primary injuries or illnesses
The term “effective dosage”, as used herein refers to a dosage which is sufficient in order for the treatment of the patient to be effective.
The term “administration of a GLP-1 compound in combination with a second compound”, as used herein refers to the administration of the two compounds in overlapping time periods, i.e. the patient is treated with the GLP-1 compound at a time where said patient is also treated with the second compound or has been treated with the second compound until 24 hours prior to the start of administration of the GLP-1 compound. Hence “administration of a GLP-1 compound in combination with a second compound” is taking place unless the administration of the second compound is stopped at least 24 hours before the start of administration of the GLP-1 compound, irrespective of whether the two compounds are administered as separate pharmaceutical compositions.
The term “medicament”, as used herein refers to a pharmaceutical composition suitable for administration of the pharmaceutically active compound to a patient.
The term “GLP-1 agonist”, as used herein refers to a molecule, preferably GLP-1 or an analogue or a derivative thereof, or exendin or an analogue or a derivative thereof, or a non-peptidyl compound, which interacts with the GLP-1 receptor and induces the physiologyical and pharmacological characteristics of the GLP-1 receptor. A GLP-1 agonist binds to the GLP-1 receptor with an affinity constant KD, below 1 μM, preferably below 100 nM. Methods for identifying GLP-1 agonists are described in WO 93/19175 (Novo Nordisk A/S). The term “GLP-1 agonist” is also intended to comprise active metabolites and prodrugs thereof, such as active metabolites and prodrugs of GLP-1 or an analogue or a derivative thereof, or exendin or an analogue or a derivative thereof, or a non-peptidyl compound. A “metabolite” is an active derivative of a GLP-1 agonist produced when the GLP-1 agonist is metabolized. A “prodrug” is a compound which is either metabolized to a GLP-1 agonist or is metabolized to the same metabolite(s) as a GLP-1 agonist.
Usually the treatment of a critical ill patent requires prolonged minute-to-minute therapy and/or observation, usually and preferably in an intensive care unit (ICU) or a special hospital unit, for example a post operative ward or the like, which is capable of providing a high level of intensive therapy in terms of quality and immediacy.
Examples of a critically ill patient is a patient in need of cardiac surgery, cerebral surgery, thoracic surgery, abdominal surgery, vascular surgery, or transplantation, or a patient suffering from neurological diseases, cerebral trauma, respiratory insufficiency, abdominal peritonitis, multiple trauma, severe burns, or CIPNP.
The glucose metabolism of a clinical ill patient may be controlled by clamping the blood glucose level within the ranges mentioned in connection with the present invention. The skilled art worker, for example, a physician, may do this using a GLP-1 compound. The skilled art worker is able to find the pharmaceutically effective amount of the GLP-1 compound used and to determine how often it is to be administered (depending on the patients weight, gender, disease condition etc.).
Conveniently, the blood glucose level is kept within the ranges mentioned in connection with the present invention for as long a period of time as the patient is critically ill. Hence, as a general rule, the blood glucose level is kept within the ranges mentioned in connection with the present invention as long as the patient is critically ill. Consequently, the blood glucose level is usually kept within the ranges mentioned in connection with the present invention for a period of time of more than about 8 hours, preferably more than about 24 hours, even more preferred more than about 2 days, especially more than about 4 days, and even more than about 7 days. In certain cases, it may even be preferred that the blood glucose level is kept within the ranges mentioned in connection with the present invention after the patient (previously) considered as being critically ill has been transferred from the Intensive Care Unit to another part of the hospital or even after said patient has left the hospital.
A critical ill patient, optionally entering an ICU, may be fed continuously, on admission with mainly intravenous glucose (for example, about 200 g to about 300 g per 24 hours) and from the next day onward with a standardised feeding schedule aiming for a caloric content up to between about 10 and about 40, preferably between about 20 and about 30, non-protein Calories/kg/24 hours and a balanced composition (for example, between about 0.05 and about 0.4, preferably between about 0.13 and about 0.26, g nitrogen/kg/24 hours and between about 20% and about 40% of non-protein Calories as lipids) of either total parenteral, combined parenteral/enteral or full enteral feeding, the latter mode attempted as early as possible. Other concomitant ICU therapy can be left to the discretion of attending physicians.
Alternatively, the following procedure can be used or it is possible to use a combination or variant of these procedures, as the physician considers advantageous for the patient : A critical ill patient may be fed, on the admission day, using, for example, a 20% glucose infusion and from day 2 onward by using a standardised feeding schedule consisting of normal caloric intake (for example, about 25-35 Calories/kgBW/24 h) and balanced composition (for example, about 20%-40% of the non-protein Calories as lipids and about 1-2 g/kgBW/24 h protein) of either total parenteral, combined parenteral/enteral or full enteral feeding, the route of administration of feeding depending on assessment of feasibility of early enteral feeding by the attending physician.

An isotonicity agent, a preservative and a buffer are added as required and the pH value of the solution is adjusted—if necessary—using an acid, e.g. hydrochloric acid, or a base, e.g. aqueous sodium hydroxide as needed. Finally, the volume of the solution is adjusted with water to give the desired concentration of the ingredients.
Examples of isotonic agents are sodium chloride, mannitol and glycerol.
Examples of preservatives are phenol, m-cresol, methyl p-hydroxybenzoate and benzyl alcohol.
Examples of suitable buffers are sodium acetate and sodium phosphate.
Further to the above-mentioned components, solutions containing a GLP-1 compound may also contain a surfactant in order to improve the solubility and/or the stability of the peptide.
According to one embodiment of the present invention, the GLP-1 compound is provided in the form of a composition suitable for administration by injection. Such a composition can either be an injectable solution ready for use or it can be an amount of a solid composition, e.g. a lyophilised product, which has to be dissolved in a solvent before it can be injected. The injectable solution preferably contains not less than about 0.1 mg/ml, typically from 0.1 mg/ml to 10 mg/ml, such as from 1 mg/ml to 5 mg/ml of GLP-1 compound.
GLP-1 compounds such as Arg34, Lys26(Nε-(γ-Glu(Nα-hexadecanoyl)))-GLP-1(7-37) can be used in the treatment of all critically ill patients and/or CIPNP patients and/or potential CIPNP patients. The optimal dose level for any patient (effective amount) will depend on the history and state of that particular patient to be treated. The person skilled in the art, e.g. a physician, will know how to determine the optimal dose level in order to control the blood glucose level within intervals mentioned herein.
Furthermore, the present GLP-1 compounds, preferably Arg34, Lys26(Nε-(γ-Glu(Nα-hexadecanoyl)))-GLP-1(7-37), may be administered in combination with one or more anti-hypertensive agents.

In a randomized, double-blind, placebo-controlled, crossover study the effect of NN2211 on beta cell sensitivity to glucose was tested in 10 subjects with type 2 diabetes following a single dose of NN2211 (7.5 μg/kg) or placebo. Using a graded glucose infusion protocol with plasma glucose levels matched over the range of 5 to 12 mmol/L beta cell sensitivity was assessed. Insulin secretion rates (ISR) were estimated by deconvolution of circulating C-peptide concentrations. Findings were compared to responses of 10 healthy, nondiabetic volunteers to the same glucose infusion protocol.
Compared to placebo, a single dose of NN2211 increased insulin and C-peptide levels, increased ISR area under the curve (AUC) (1130±150 vs. 668±106 pmol/kg; p<0.001), and increased slope of ISR vs. plasma glucose (1.26±0.36 vs. 0.54±0.18 pmol*L/(min*mmol*kg); p<0.014), to values similar to nondiabetic controls who did not receive the drug (ISR AUC 1206±99; slope of ISR vs. plasma glucose 1.44±0.18). No hypoglycemic events occurred. Importantly insulin secretion was comparable to the non-diabetic controls at low glucose levels.
A single dose of the long-acting GLP-1 derivative, NN2211, improves beta cell sensitivity to physiological hyperglycemia in type 2 diabetes patients, and confirms that NN2211 provides a glucose-dependent insulin secretion.
In a prospective, 12 week, randomised, double-blind, dose-response, placebo controlled and open label glimepiride study in subjects with type 2 diabetes, the glucose lowering effect of NN2211 was tested with the primary endpoint being the effect on HbA1c after 12 weeks treatment (a recognised measure of overall glycaemic control).
For the primary endpoint of the study HbA1c decreased in all NNC 90-1170 treatment groups, except the one at the lowest dosage. In comparison to the placebo group the decrease was statistically significant for the two highest doses (0.60 and 0.75 mg). After 12 weeks treatment the mean decrease compared to placebo in HbA1c was 0.70 and 0.75 percentage points in the 0.60 and 0.75 mg groups, respectively (p=0.0002 and p<0.0001, respectively.). Furthermore, mean serum fasting glucose decreased by 2.14 and 1.82 mmol/L after 12 weeks in the 0.60 and 0.75 mg NNC 90-1170 dose groups, p<0.0001 and p=0.0003, respectively, compared with placebo. The effect of glimepiride after 12 weeks treatment a reduction compared to placebo of 0.74% (p=0.0001), and −2.6 mM, on HbA1c and FSG, respectively. These effects were not statistically different from the two highest doses of NN2211.
Furthermore, there were 7% of the subjects that reported any hypoglycaemic episode in the two highest dose groups of NN2211, as opposed to 31% in the glimepiride group.
This study demonstrates that NN2211 improves glyceamic control in patients with type 2 diabetes, and furthermore, the low incidence of any hypoglycaemic event also in comparison to glimepiride (that acts by stimulating insulin secretion), corroborates the glucose dependent insulin secretion of NN2211 described in example 1, and suggests its therapeutic advantage on the side effect profile as compared to exogenous insulin administration that is known to be associated with hypoglycaemia if dosing is not carefully titrated. Furthermore, the once daily dosing regimen of NN2211 would be a therapeutic advantage compared to a carefully titrated insulin administration regimen.
Serves as an example of a study that could determine the effect of NN2211 in critically ill patients in comparison to intensive insulin treatment.
All mechanically ventilated, adult (age>18 y) patients.
At ICU admission, and following informed consent, patients are randomized to either strict control of glycemia below 6.1 mmol/L (110 mg/dL) with continuously infused insulin, the ‘intensive insulin schedule’ (IIS), or using NN2211 given once daily (1-5 mg).
At baseline, demographic, diagnostic and therapeutic information as well as information necessary to determine severity of illness and utilization of ICU resources are obtained from each patient. These include APACHE-II (Acute Physiology and Chronic Health Evaluation) score with higher values indicating more severe illness and simplified Therapeutic Intervention Scoring System (TISS-28) with higher values indicating a higher number of therapeutic interventions. APACHE II and TISS scores are calculated daily from ICU admission to discharge or death.
Continuous blood samples for glucose, clinical chemistry, hematology and markers of inflammation, blood culture (if appropriate). Furthermore, electromyography (EMG) to screen for Critical Illness Polyneuropathy, and in case of ICU death, a post-mortem examination is performed to confirm the presumed cause of death.
The primary endpoint would be death from all causes during intensive care. Secondary outcome measures are in-hospital mortality, incidence of prolonged intensive care dependency and need for ICU re-admission, need for vital organ system support comprising mechanical ventilatory support, renal replacement therapy (continuous or intermittent hemofiltration or dialysis), inotropic or vasopressor support, incidence of critical illness polyneuropathy, the degree of inflammation, incidence of blood stream infections and use of antibiotics, transfusion requirements and incidence of hyperbilirubinemia. Furthermore, use of intensive care resources should be analysed by cumulative TISS scores. In order to accurately and objectively assess duration of ICU stay, which is often influenced by non-patient related factors such as bed availability on regular wards, patients are defined as ‘dischargable from ICU’ when they were no longer in need of vital organ system support and received at least ⅔rd of the caloric need through the normal enteral route or earlier when actually sent to a ward.
By using published data on variability of the mortality endpoint, together with an expectation of showing a similar effect as intensive insulin therapy (non-inferiority) a sample size calculation are performed in order to determine the number of subjects needed to be recruited.
