Brief Summary

This is a randomized, double-blind, placebo-controlled study evaluating the effects of aleniglipron on body composition in participants living with obesity. Participants will be randomized to aleniglipron or placebo in a ratio of 5:1. Participants will receive multiple ascending QD doses of aleniglipron or placebo in titration steps of 4 weeks duration for a total of 40 weeks of treatment.
