A Study to Assess Efficacy, Safety, Tolerability, Pharmacokinetics (PK) and Pharmacodynamics (PD) of RO7204239 in Combination With Tirzepatide in Participants With Obesity or Overweight With At Least One Weight-related Comorbidity (GYMINDA) Phase 2 285 Randomized

Active, not recruiting
Clinical Trial NCT06965413 (GYMINDA) is designed to study Treatment for Obesity, Overweight, Overweight With One Weight Related Comorbidity. It is a Phase 2 interventional study that is active, not recruiting, having started on May 5, 2025, with plans to enroll 285 participants. Led by Hoffmann-La Roche, it is expected to complete by July 23, 2027. The latest data from ClinicalTrials.gov was last updated on February 12, 2026.
Brief Summary
The main aim of the study is to assess the effect of RO7204239 in combination with tirzepatide, compared to placebo in combination with tirzepatide, on body weight loss after 48 weeks of treatment in adults with obesity or overweight with at least one weight-related comorbidity, but without diabetes mellitus (DM). The study comprises of a 4-week screening period; a 48-week core treatment period, where all participant...Show More
