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.
Oxyntomodulin
Human studies showed acute reductions in food intake and modest weight loss, helping establish the GLP-1 and glucagon co-agonism concept. It remains a foundational peptide for obesity and satiety research.
