MOD-6031 is a long-acting reversibly PEGylated oxyntomodulin (OXM) therapeutic. The active moiety is a gastrointestinal neuropeptide with a sequence identical to endogenous human OXM and is an agonist for both glucagon-like peptide-1 (GLP1) and glucagon (GCG) receptors. The peptide is a natural appetite suppressant, secreted by L-cells in the digestive system following food intake leading to a decrease in gastric emptying, satiety after crossing the blood-brain barrier, and regulation of insulin and glucose levels. Thus, MOD-6031 is being developed as a treatment for high risk subjects (obese) to increase weight loss, reduce food intake and increase glycemic control.
