Tamer Coskun, MD, PhD
Biography & Research Background
Tamer Coskun, MD, PhD, is a senior researcher at Eli Lilly and Company (Indianapolis, IN, USA) and a key figure in the discovery and early development of retatrutide (LY3437943). He served as the lead author on the foundational 2022 publication in Cell Metabolism detailing the molecule's discovery, mechanism of action, and proof of concept from preclinical models through Phase 1 human data. Dr. Coskun has been a senior or co-author on subsequent Phase 2 clinical trials, including substudies focusing on body composition, eating behavior, and kidney parameters. His research contributions span the entire translational pipeline of retatrutide, from molecular design through clinical validation. His key publications include "LY3437943, a novel triple glucagon, GIP, and GLP-1 receptor agonist for glycemic control and weight loss: From discovery to clinical proof of concept" (2022, Cell Metabolism) and "Effects of retatrutide on body composition in people with type 2 diabetes" (2025, The Lancet Diabetes & Endocrinology).
