Administration of the triple agonist peptide GEP44 to diet-induced obese rats produces greater reductions in body weight and food intake compared to the GLP-1 receptor agonist liraglutide, while avoiding the nausea and malaise associated with high-dose GLP-1RAs.

This preclinical data suggests that combining GLP-1 activity with Neuropeptide Y1 and Y2 receptor agonism may offer a path to more effective weight loss than current GLP-1 drugs alone, potentially without the common side effect of nausea. This is not yet a human treatment but highlights a promising direction for peptide-based obesity therapies.

The rats treated with GEP44 exhibited notably larger reductions in both body weight... and food intake... compared to rats treated with LIRA... By contrast, we were able to continue the dose escalation in rats treated with GEP44... with no indication of malaise.
