Type 2 diabetes is a major risk factor for cardiovascular disease related morbidity and mortality. Glucagon-like peptide 1 (GLP-1) belongs to the hormonal family of incretins that enhance the secretion of insulin.
Differential processing of proglucagon in the intestinal epithelial endocrine L-cells produces the 30-amino acid peptide hormone GLP-1. It is assumed that GLP-1 may be involved in the stimulation of glucose disposal in peripheral tissues independent of insulin actions. GLP-1 and GLP-2 stimulate intestinal growth and upregulate villus height in the gastrointestinal tract. Exenatide (exendin-4) is a reptilian hormone isolated from the saliva of the Gila monster (Heloderma suspectum) which acts as a GLP-1 mimic. Oral glucose stimulates the release of the endogenous incretins glucagon-like peptide-1 (GLP-1) and glucose-dependent insulin-releasing polypeptide (GIP). In summary it is projected that GLP-1 agonist peptides against type-2 diabetes are promising targets for patients with poor Hb1Ac control.

JARDIANCE is not for people with type 1 diabetes or for people with diabetic ketoacidosis (increased ketones in the blood or urine). There are several therapies for the management of type 2 diabetes, but still optimal glycemic control is not achieved in spite of advances in options for the treatment of diabetes. Incretins are a group of gastrointestinal hormones that stimulate lower blood glucose levels by increasing the amount of insulin released from pancreatic beta cells.
The pancreas and the central nervous system (CNS) also secrete this hormone in smaller quantities. The metabolism of GLP-1 in the body is extremely rapid and the peptide gets inactivated by the enzyme dipeptidyl peptidase-4 (DPP-4), even before leaving the gut.


The 39 amino acid-containing peptide has been approved as a monotherapy for the treatment of type-2 diabetes. These stimulate insulin release and inhibit glucagon release resulting in lower blood glucose.
Exenatide once a week dose was more effective when compared to twice a day dose of exenatide. Further effects are an increase of the net blood brain clearance and the brain metabolism, but it is not known whether they depend on the prevailing plasma glucose (PG) (6).
I feel proud to be part of Bachem team and its contribution towards bringing better medicines into the market. Then use the boxed letters from the solved amino acid words to get the scrambled peptide name. Constituted from both Lixisenatide and insulin glargine Lantus, LixiLan is developed to tackle type 2 diabetes when both oral medication fails and basal insulin loses its efficacy. A large number of patients fail to attain the glycemic target and only few drugs have shown to effectively control the Hb1Ac numbers below <7%.
The two primary incretin hormones are glucagon like peptide GLP-1 and GIP (gastric inhibitory polypeptide or glucose-dependent insulinotropic polypeptide).
GLP- 1 stimulates the release of insulin from the pancreas; it also increases the volume of cells in the pancreas which produces insulin (beta cells) and regulates and controls the release of glucagon.
It has an essential function in nutrient homeostasis (5) by an increased stimulus in the gastrointestinal track which leads to an increment in nutrient assimilation.
In clinical practice these therapies are associated with significant reductions in glycated hemoglobin (HbA1c) weight loss and a low risk of hypoglycemia. Because of its shorter half-life of 2.4 hours exenatide has twice-a-day dosing regimen taken with metformin A± sulfonylurea. The fatty acid side chain enables the heptamer formation thus increasing the stability and the binding to albumin. GLP-1 peptide is a post- translational product of preglucagon which is a precursor of many glucagon related peptides. Prior to that I was working as Research Scientist at drug delivery company designing prodrugs to make them more bioavailable and less toxic. Source: SanofiLixisenatide (Lyxumia outside the US) was initially discovered by Zealand Pharma, who licensed out the drug to Sanofi for development as a once-per-day injection of a prandial GLP-1 agonist (which stimulates an increase in insulin secretion, lowering blood glucose). The biggest hurdles for the implementation and long term application of intensive therapies are the low blood sugar levels (hypoglycemia) and weight gain.
GLP-1 acts on appetite centers in brain, slowing the emptying process in stomach and increasing the feeling of fullness during and between the meals. The Pharmaceutical industry has developed drugs that mimic the GLP-1 targeting control of glucose levels in type-2 diabetes. The DPP-4 inhibitors prolong the action of endogenous incretins, enhancing the first-phase insulin response. The drug was generally well tolerated and rates of hypoglycemia seemed to be low in these trials; however frequency of hypoglycemia increased with the combined use of other anti-diabetic drugs (metformin and sulfonylurea drugs). They are two equipotent forms of GLP-1, GLP-1 (7-36)-NH2 and GLP-1 (7-37), the first one being more abundant, which bind to and activate the GLP-1 receptor. Working as bench scientist I gained knowledge about different disease areas, drugs that treat them and their mechanism of action on diseases.


However, competition of Lixisenatide side-project was already fierce, with Victoza by NovoNordisk already being a super-GLP-1-agonist blockbuster. Currently available drugs act to increase insulin availability through administration, secretion or by increasing sensitivity.
GLP-1 is a product of a precursor molecule called pre-proglucagon, a polypeptide which is split to produce many hormones including glucagon.
It regulates blood glucose by decreasing glycolysis and increases the rate of gluconeogenesis. Weight loss contributes in increasing the GLP-1 levels leading to improved glucose control in Type-2 Diabetes. It was reported that in direct comparison between exenatide twice daily and liraglutide once a day, liraglutide was significantly more effective in controlling the glycemic index when compared to exenatide. The GLP-1 receptor or GLP-1R belongs to the class B family of G-protein coupled receptors (GPCRs) and carries out its regulatory functions.

Others act by delaying the delivery and absorption of carbohydrate from the gastrointestinal tract, or by increasing urinary glucose excretion.
As they have same origin, these hormones share some similarities, and hence the name a€?glucagon-likea€™. It counter-regulates the hormone of insulin by raising plasma glucose levels in response to insulin-induced hypoglycemia. Lower levels of GLP-1 in the body lead to obesity, feeling of hunger and empty stomach making the individual eat more. Previously unrivaled, Lantus has dominated the market for years, earning Sanofi up to €6.2Bn last year in revenue. There still seems to be an unmet need in this therapeutic area, in spite of these drugs on the market. Glucagon is known to play an important role in initiating and maintaining hyperglycemic conditions in diabetes and to suppress the plasma glucagon level.
However, since the Lantus patent expired in February of this year, various competitors have started  to eat away at sales, including Eli Lilly’s biosimilar Abasaglar.
Recently there have been advances in type 2 diabetes management in the clinical development of dipeptidyl peptidase-4 (DPP-4) inhibitors and in glucagon-like peptide 1 receptor agonists. For this reason, Sanofi hopes the launch of its new combination drug LixiLan will revive the Lantus demand. With positive results from the phase III trials, Sanofi is anticipating a regulatory submission to US FDA in late 2015 and the EMA in early 2016.Zealand Pharma is looking forward to cashing in on the scheduled marketing milestone payments from Sanofi, which amass a total of €141M.
