The present invention relates to an oral, algal oil-based, gastro-intestinal tract (GIT) permeable peptide composition. Particularly, the invention relates to oral, algal oil-based peptide compositions for the treatment of metabolic disorders comprising peptides that are generally degraded in the GIT, a protease inhibitor, and a chelating agent in the presence of water in an algal oil along with pharmaceutically acceptable excipients. Particularly, the composition of the present invention is useful for treating glucose metabolism disorders.
Metabolic disorders (MDs) are characterized by the inability of the body to properly utilize and/or store energy. Metabolic disorder is a collection of cardio metabolic risk factors that include obesity, insulin resistance, hypertension, dyslipidemia, cognitive decline including decreased mental flexibility and memory deficits. Metabolic disorders are a cluster of conditions that occur together which include increasing risk of heart disease and stroke. Metabolic disorders also include increased blood pressure, high blood sugar, excess body fat around the waist and abnormal cholesterol or triglyceride levels. Metabolic disorders are increasingly common and up to one-third of the population suffers from them. Metabolic disorders could lead to serious health problems in the future, if not diagnosed properly in time. Metabolic disorders are mainly caused due to defective processing or transport of amino acids, fatty acids, sugars, and metals. More particularly, it is an enzyme deficiency leading to the disruption of normal bodily metabolism.
Diabetes mellitus (DM), commonly known as diabetes, is a metabolic disease that causes high blood sugar. The hormone insulin moves sugar from the blood into body cells to be stored or used for energy.
The global diabetes prevalence in 2019 was estimated to be 9.3% (463 million people), which will rise to 10.2% (578 million) by 2030 and 10.9% (700 million) by 2045. The prevalence is higher in urban (10.8%), than rural (7.2%) areas, and in high-income (10.4%) than low-income countries (4.0%). One in two (50.1%) people living with diabetes do not know that they have diabetes. The global prevalence of impaired glucose tolerance was estimated to be 7.5% (374 million) in 2019 and is projected to reach 8.0% (454 million) by 2030 and 8.6% (548 million) by 2045. [Diabetes research clinical practice 157, 107843, 2019]
Diabetes affects approximately 30.3 million people (9.4% of the population) in the United States, while another estimated 84.1 million people have prediabetes and do not know it. An estimated 7.2 million people in the United States have diabetes and do not even know it. In the past few years, diabetes has been the 7th leading cause of death listed on death certificates in the United States.
As on date, most of the biomolecules are administered through the parental route of administration which has very low patient compliance. Repeated administration of a parenteral formulation causes lipoatrophy or lipohypertrophy. There are other adverse effects such as peripheral hyperinsulinemia, peripheral hypertension, the development of atherosclerosis, cancer, hypoglycaemia, and other adverse metabolic effects.
It is generally known that major biomolecules have low oral activity because of the way these substances are absorbed from the digestive system. Pharmacological studies indicate that biomolecules are absorbed from the intestines and carried by the blood through the portal system to the liver where they are rapidly inactivated by enzymatic reactions.
Particularly, the oral route carries biomolecules such as insulin directly to the liver through portal circulation, which is what also occurs in non-diabetic individuals. Adequate levels of insulin in the portal circulation are associated with a rapid and significant lowering of plasma glucose and haemoglobin A1c levels. Moreover, oral administration reduces systemic insulin exposure, and peripheral hyperinsulinemia.
Several attempts have been made to overcome the above obstacles by using approaches such as liposome delivery (U.S. Pat. No. 4,356,167), lipid coating (U.S. Pat. No. 4,849,227, WO8705505), use of peptidase inhibitors (U.S. Pat. No. 4,579,730), prodrugs, targeted microspheres (WO88/01213), coacervate systems (U.S. Pat. No. 4,849,405) or, lately, emulsion formulations. However, the prior art documents identified above have major disadvantages such as pH-sensitivity, promotion of unwanted expedited release, disaggregation, poor entrapment efficiency and poor stability in biological fluids.
Proteases, also called peptidases or proteinases, are enzymes that perform proteolysis. Proteolysis is one of the most important biological reactions. Proteolytic activity has been attributed to a class of enzymes called proteases. Based on the mechanism of action, proteases are classified as either serine, cysteine, or threonine proteases (amino-terminal nucleophile hydrolases), or as aspartic, metallo and glutamic proteases (with glutamic proteases being the only subtype not found in mammals so far).
Proteolytic enzymes help break down and digest protein. They are found in the body, as well as in certain foods and dietary supplements. Proteolytic enzyme supplements have recently grown popular due to health benefits. Bromelain, papain, pancreatin, trypsin and chymotrypsin are proteolytic enzymes that are commonly added to proteolytic supplement blends.
A trypsin inhibitor (TI) is a protein and a type of serine protease inhibitor (serpin) that reduces the biological activity of trypsin by controlling the activation and catalytic reactions of proteins. Trypsin is an enzyme involved in the breakdown of many different proteins, primarily as part of digestion in humans and other animals such as monogastric and young ruminants. When a trypsin inhibitor is consumed, it acts as an irreversible and competitive substrate.
There are various studies going on to develop an oral formulation of peptides with protease inhibitor. Some glucagon-like peptide-1 (GLP-1) receptor agonists like semaglutide available in oral dosage form frequently exhibit side effects such as risk of thyroid C-cell tumors, diabetic retinopathy complications, pancreatitis, acute kidney injury, serious hypersensitivity reactions in patients.
Certain compositions use fish oil comprising an omega-3 fatty acid. However, use of fish oil has well known disadvantages. Taking more than 3 grams per day might keep blood from clotting and increase the chances of bleeding. Fish oil can cause side effects including belching, bad breath, heartburn, nausea, loose stools, rash, nosebleeds, and high blood sugar. Fish oil accumulates toxins such as mercury, dioxins, and polychlorinated biphenyls (PCBs), and spoiled fish oil may produce peroxides. Although fish oil is the richest source of essential Omega-3 fatty acids EPA and DHA, the fishy odour, unstable nature, low purity, delivery form as capsules are major limitations of its use.
Krill oil (KO) is rich in polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have many health benefits. However, the oil is unstable owing to its high degree of unsaturation. The oil was microencapsulated using maltodextrin, saponin and sodium cascinate and rosemary oil (RO) extract or sodium ascorbate. [Food Hydrocolloids for Health Volume 1, 2021, 100031]
WO90/03164 discloses the use of oral proteinaceous compositions comprising oil/water emulsions which form chylomicra or deliver chylomicra to absorption sites in the gastrointestinal tracts. The compositions of WO'164 have drawbacks since oil/water emulsions are known in the art to have stability problems and involve denaturation of proteinaceous material due to heat and shear involved in the process.
U.S. Pat. No. 8,088,734B2 discloses enhancing bioavailability of peptide like salmon calcitonin to be administered orally is enhanced by acyl carnitines. WO1991004743A1 discloses a method for producing a stable preparation of a pharmaceutical peptide comprising stabilizing a solution of peptide in a physiologically acceptable aqueous buffer. More particularly, the invention relates to a formulation for stabilizing thymopentin in a low concentration. U.S. Pat. No. 6,034,054A provides a monomeric insulin formulation stabilized against aggregation in which the buffering agent is either tromethamine or arginine.
With respect to safety and convenience considerations, oral delivery satisfies the physiologic mode for biomolecules. To boost medication compliance, there is an immediate need to develop an oral delivery system for biomolecules which are site specific with accurate dosing, causing the biomolecule being administered to perform natural function more consistently, efficiently, and expediently. Also, the oral administration may avoid the cumbersome and expensive parenteral administration process with improved bioavailability.
Particularly the gastro-intestinal tract has many physiological barriers which prevent optimal delivery of oral peptide. Physiological function of the gut enzymes is to break large “active” proteins into smaller “inactive” amino acids so that they can overcome the second absorption barrier “tight epithelium” in the gastro-intestinal tract.
These two essential barriers have been created by Mother Nature to prevent body from potentially dangerous proteins. Researchers are trying to selectively break this natural defence mechanism so that helpful large “active protein” drugs can cross this barrier and produce desired pharmacological effects. Therefore, the need arises to co-administer the active proteins with enzyme inhibitors that improves the GIT absorption of protein for better efficacy.
In the current scenario, there is a need for an alternate source of oil enriched with omega-3 fatty acid preferably docosahexaenoic acid (DHA). It has been observed that docosahexaenoic acid alters the permeability of intestinal brush border membrane, making the intestinal brush border membrane more permeable to GIT degradable peptides, thereby enhancing intestinal peptide absorption. An emulsion incorporating highly purified long-chain polyunsaturated fatty acid, especially docosahexaenoic acid, has the potential of becoming the formulation for enteral delivery of peptides without intestinal wall damage.
Algal oil is a plant-based source of EPA and DHA, two omega-3 fats that are essential for human health. It may provide a great plant-based alternative if one doesn't cat seafood or can't tolerate fish oil. Even with advances in micro-encapsulation and other stabilization and oxidation inhibiting technologies, stability is still an issue with some omega-3-oils.
Moreover, stability will always be an issue for oils rich in eicosatetraenoic acid (EPA) and docosahexaenoic acid (DHA) as polyunsaturated fatty acids are very sensitive by nature to oxidation, which causes the fast degradation of volatile compounds. Hence it needs to be protected from oxidation.
By knowing the current scenario with regards to use of DHA, the present inventors have performed rigorous experiments and come up with a new vegan source enriched with docosahexaenoic acid, wherein this docosahexaenoic acid exhibits high oxidative stability and enhances oil-solubility and stability of the biomolecule, particularly GIT degraded peptides.

Emulsions are colloidal systems consisting of two liquid phases, oil and water, one of which is dispersed into the other. Water-in-oil (W/O) emulsions consist of an aqueous phase dispersed, in the form of small droplets, into a continuous oil phase.
Water-in-oil (W/O) emulsions have high potential for several industrial areas as delivery systems of hydrophilic compounds. In general, they are less studied than oil-in-water (O/W) systems, namely in what concerns the so-called fluid systems, partly due to problems of instability.
Water in oil emulsions are colloidal systems having water droplets dispersed throughout the oil. Therefore, oil acts as the continuous phase of this colloid while water is the dispersed phase. Oil does not mix with water under normal conditions. But with proper mixing and by using stabilizing agents, it can obtain oil in water emulsion. The effectiveness of this system enhances with a small size of dispersed oil droplets. It increases the bioavailability of the present composition, and it also increases the shelf life of the composition.

A study of Composition-3 vs Januvia (Sitagliptin) vs Placebo in adult patients with inadequate glycemic control
The pivotal study was involved 36 patients divided in to 3 groups of 12 each randomized to 1:1:1 into three cohorts dosed with 8 mg of Composition-3at night, Januvia 100 mg (Sitagliptin) at night and placebo at night.
Patient population-T2D adult patients above age of 21 years with inadequate glycemic control who were managing their condition with diet and metformin monotherapy.
Composition-3 significantly reduces blood sugar level subjects over the marketed anti-diabetic drug i.e., Sitagliptin. More particularly, sitagliptin reduces HbA1c level by 14.7% whereas composition 1 reduces HbA1c level by 22%. Fasting Plasma Glucose (FPG) level was reduced up to 20% by sitagliptin and up to 30% by Composition-1. Hence, it was proved that the Composition-1 as claimed in the present invention is effective in the treatment of diabetes with novel oral formulation without any severe side effects.
It may be noted that sitagliptin can cause serious side effects, including pancreatitis, which may be severe and lead to death. Sometimes it may cause increasing shortness of breath or trouble breathing and heart problems. The risk of getting low blood sugar is higher when taken along with sulfonylurea medicine or insulin.
