A Master Protocol for a Randomized, Controlled, Clinical Trial of Multiple Interventions for Chronic Weight Management in Adult Participants With Obesity or Overweight

๐ŸŸข Recruiting Phase2 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Eli Lilly and Company

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The purpose of this Phase-2 chronic weight management master protocol (CWMM) is to create a framework to evaluate the safety and efficacy of various investigational interventions for chronic weight management with intervention-specific appendices (ISAs). The CWMM establishes entry criteria for newly enrolled participants across the master and the ISAs. The ISAs may start independently of other ISAs as interventions become available for clinical testing. The results for the CWMM screening record will be reported when all the ISA's complete.
