Research Overview

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.

HM15211

Research has shown potent weight-reducing and metabolic effects in preclinical and translational studies. The compound is being developed as a next-generation incretin-based therapy.
