Obesity and Overweight
Conditions
Brief summary
This study evaluates the safety, tolerability, pharmacokinetics and pharmacodynamics of IBI3046 in Chinese overweight or obese participants, comprising four phases: single ascending dose (SAD), multiple ascending dose (MAD), IBI3046 administration after mazdutide discontinuation, and IBI3046 in combination with mazdutide
