NCT ID NCT06911203
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 2 trial compares a new drug, BGM0504, to the existing weight-loss drug tirzepatide in 90 adults with obesity (BMI 35-45) who do not have diabetes. Participants will receive one of the two drugs for 26 weeks to see which leads to greater weight loss and improvements in health measures like waist size and blood pressure. The study is currently recruiting.

- What this could lead to
- If BGM0504 works as well or better than tirzepatide, it could offer a new weight-loss option for people with obesity.
- What could go wrong
- This is an early Phase 2 trial with only 90 people, so results may not apply broadly. Side effects or lack of effectiveness are possible.
