Summary

This early-stage study tested a new drug called LY3532226 in 132 people with obesity to see if it is safe and how the body processes it. Participants received weekly or monthly doses, and researchers monitored side effects and drug levels in the blood. The goal was to gather safety information, not to measure weight loss.
