“Phase 3 trials showed retatrutide produced average weight reduction above 20%.”

A verdict on this wording and scope, not a universal grade for Retatrutide.

01 · Verdict

Supported with scope

Lilly reported average weight reduction of up to 20.8% in TRIUMPH-2 and up to 22.6% in TRIUMPH-3 at 80 weeks. These are sponsor-reported topline efficacy-estimand figures and group averages, not individual outcomes, and no full peer-reviewed report of either trial was available in the records reviewed here.

Scope
Adults meeting the TRIUMPH-2 (obesity or overweight with type 2 diabetes) and TRIUMPH-3 (severe obesity with established cardiovascular disease) entry criteria at 80 weeks, as disclosed by Lilly in July 2026.
