RETATRUTIDE / PHASE 2 / 2023

Retatrutide: glucose and weight in type 2 diabetes

Could triple-receptor activity improve glucose regulation as well as body weight?

Who was studied?

Adults with type 2 diabetes were randomized to retatrutide, placebo or dulaglutide. HbA1c change at 24 weeks was the primary endpoint.

Participants
281 adults
Duration
36 weeks
Funding
Eli Lilly

What did the study find?

At 36 weeks, mean weight reduction in the 12 mg escalation group was 16.94%, versus 3.00% with placebo and 2.02% with dulaglutide 1.5 mg. The paper also reports glucose-lowering efficacy.

What should you keep in mind?

This was a phase 2 comparison with a particular dulaglutide regimen, not all diabetes treatments. Gastrointestinal adverse events and different escalation groups affect interpretation.

Why it matters

The study extends the question beyond weight loss to glycemic control. It does not establish an approved prescription or a personal dosing schedule.
