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
tirzepatide
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.
