Summary

This early-stage study tested whether adding a new drug (LY3841136) to an existing weight-loss medication (tirzepatide) is safe and tolerable. 96 healthy overweight or obese adults took part over about 42 weeks. The main goal was to check for side effects, not to prove weight loss, though changes in body weight were also measured.
