Frequently Asked Questions
What weight loss results has retatrutide shown in trials?
Phase 2 trial data published in the New England Journal of Medicine showed participants lost up to 24.2% of body weight at the highest dose over 48 weeks[1]. Phase 3 trials are evaluating these results in larger, more diverse patient populations.
When will retatrutide be available?
Retatrutide is currently in Phase 3 clinical trials. If trial results are positive, Eli Lilly could submit for FDA approval as early as 2025-2026, with potential commercial availability following approval. Timelines are subject to change based on regulatory review.
How does retatrutide differ from semaglutide and tirzepatide?
Retatrutide is a triple agonist targeting GLP-1, GIP, and glucagon receptors simultaneously, compared to semaglutide (GLP-1 only) and tirzepatide (GLP-1 and GIP). This triple mechanism showed higher average weight loss in early clinical trials.
