A Study of IBI3032 in Chinese Healthy Participants and Participants With Overweight or Obesity

This is a randomized, double-blind, placebo-controlled phase 1 clinical study evaluating the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of a single ascending dose of IBI3032 in healthy participants and multiple ascending doses of IBI3032 in participants with overweight or obesity. It consists of 2 parts: Part A is a single ascending dose (SAD) study in healthy participants, and Part B is a multiple ascending dose (MAD) study in participants with overweight or obesity during the 4-week treatment period.

Primary outcomes

  1. Number of Participants with adverse events (AEs)

    Time frame: Part A: Baseline up to Day 15

    An adverse event (AE) is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related.

  2. Number of Participants with adverse events (AEs)

    Time frame: Part B: Baseline up to Day 43

    An adverse event (AE) is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related.

  3. Number of Participants with One Serious Adverse Event(s) Considered by the Investigator to be Related to Study Drug

    Time frame: Part A: Baseline up to Day 15

    A summary of SAEs regardless of causality, will be reported in the Reported Adverse Events module.

  4. Number of Participants with One Serious Adverse Event(s) Considered by the Investigator to be Related to Study Drug

    Time frame: Part B: Baseline up to Day 43

    A summary of SAEs regardless of causality, will be reported in the Reported Adverse Events module.

  5. Number of Participants with More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug

    Time frame: Part A: Baseline up to Day 15

    A summary of other non-serious adverse events (AEs), regardless of causality, will be reported in the Reported Adverse Events module.

  6. Number of Participants with More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug

    Time frame: Part B: Baseline up to Day 43

    A summary of other non-serious adverse events (AEs), regardless of causality, will be reported in the Reported Adverse Events module.
