Phase 2 Study of Multiple Investigational Weight Management Treatments Using Injection and Oral Medications for Adults with Obesity or Overweight

What this Trial Is About

This research focuses on adults with obesity or overweight and aims to evaluate the safety and effectiveness of various investigational treatments for chronic weight management. It is a Phase 2 master protocol study that uses a framework to test multiple interventions, each detailed in separate appendices. The study establishes criteria for enrolling new participants and reports results when all intervention appendices have completed. Participants may receive different investigational drugs administered either by subcutaneous injection or orally, including LY3305677, LY3841136, tirzepatide, LY3549492, and others. Each intervention-specific appendix outlines the particular treatment details and analyses. Some participants receive placebos matching the administration method of the active treatments. Treatments and analyses are conducted in parallel groups, and interventions may start independently as they become available. Throughout the study, participants undergo screening to confirm eligibility and are randomly assigned to one of the intervention groups or placebo. Researchers monitor participant allocation up to week 6. The trial emphasizes double-blind procedures, and participant involvement includes receiving study treatments and attending scheduled visits. Safety and efficacy data are collected, and the study is planned to continue until early 2028, with primary outcome measures focusing on participant allocation to interventions.
