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.

UBT251

Published work supports strong anti-obesity activity in preclinical models, with translation into human studies still emerging. The compound remains investigational and is best characterized as an early multi-agonist program.
