Research Overview
Dulaglutide
Dulaglutide has repeatedly shown small-to-moderate reductions in body weight alongside glycemic improvement in large diabetes trials. It is a useful comparator for GLP-1 receptor agonist effects on appetite and weight.
Cotadutide
Phase 2 studies reported dose-dependent weight loss and favorable changes in glycemic and liver-related markers. It is one of the most cited synthetic dual-agonist peptides for obesity research.
