TRIUMPH-2: Retatrutide Research in Type 2 Diabetes

September 9, 2026 • Human Research

🧬 RETATRUTIDE + TYPE 2 DIABETES RESEARCH

TRIUMPH-2 looked specifically at adults with obesity or overweight and type 2 diabetes.

At 80 weeks, reported average body-weight reductions were 12.7%, 19.1%, and 20.8% across the 4 mg, 9 mg, and 12 mg trial groups.

Average A1C reductions reached up to 1.6 percentage points.

That population matters. Results in people with type 2 diabetes shouldn’t automatically be treated as interchangeable with results from every other obesity trial.

Retatrutide remains investigational and is not FDA-approved as of this post. 🧬
