Mazdutide: Research & Evidence

Established Evidence

Published research, clinical trial data, and evidence grading for Mazdutide across studied indications.

Back to Mazdutide overview

Research Summary

Mazdutide has approximately 5-10 completed RCTs, primarily in Chinese populations. The Phase 3 GLORY-2 trial demonstrated up to 20.1% weight loss at 9 mg in adults with obesity. The Phase 3 DREAMS-3 head-to-head trial showed superiority over semaglutide in both glycemic control and weight loss. NMPA (China) approved mazdutide in September 2025 for Type 2 Diabetes glycemic control — making it the world's first approved GCG/GLP-1 dual agonist. However, mazdutide is NOT FDA approved and has no active US IND as of March 2026. All clinical data comes from Chinese populations; efficacy in other ethnic groups is not established.
