Mazdutide- Summary
- Tirzepatide is an FDA-approved dual GIP/GLP-1 receptor agonist that produces greater weight loss than semaglutide in head-to-head trials. SURMOUNT-1 trial showed average 21% body weight reduction at 72 weeks at the highest dose. Marketed as Mounjaro (diabetes) and Zepbound (obesity).
- Mazdutide is a once-weekly GLP-1/glucagon dual receptor agonist developed by Innovent Biologics and Eli Lilly. Phase 2 trials in Chinese populations demonstrated up to 11.3% body weight reduction at 6 mg over 24 weeks. It also improves liver fat, glycemic control, and lipid profiles. Phase 3 trials are ongoing primarily in China.
