Summary

This Phase 2 trial is testing several experimental drugs—including tirzepatide and others—for long-term weight management in adults with obesity or overweight. About 1,481 participants will receive one of the drugs or a placebo. The goal is to see if these treatments are safe and help with weight loss over time.
