NCT ID NCT06037252
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tests different doses of tirzepatide in 414 adults with type 2 diabetes and obesity who already take metformin. The goal is to see if the drug helps with weight loss and blood sugar control. Participants receive either tirzepatide or a placebo for about 89 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance

- What this could lead to
- If successful, this could lead to a new treatment option that helps people with type 2 diabetes and obesity lose weight and better control their blood sugar.
- What could go wrong
- This is a phase 2 trial, so it's still early. The drug may not work better than placebo, and side effects are possible. Results may not apply to everyone with diabetes.
