Research Overview

Setmelanotide

Setmelanotide has shown clinically meaningful reductions in hunger and weight in POMC, PCSK1, and LEPR-related obesity. It is one of the most important mechanistic peptides for rare-disease obesity research.

Efinopegdutide

Human trials have shown meaningful weight loss and improvements in hepatic steatosis biomarkers. It remains a research compound with ongoing development in metabolic disease.
