Study Summary

The purpose of this trial is to evaluate the efficacy and safety of GV101 for weight loss over a range of doses in participants with obesity. The primary efficacy endpoint is the mean percent change in body weight from baseline at Week 16 in each treated group as compared with placebo.

Eligibility Criteria

  3. Except for obesity, otherwise healthy, as determined by the Investigator ormedically qualified designee based on a medical evaluation including medicalhistory, physical examination, laboratory tests, and ECGs at screening.
