What this trial studies
This Phase 2, master protocol study examines the body weight lowering effects and safety of macupatide and eloralintide, alone or in combination, in adults with overweight or obesity who do not have type 2 diabetes. Participants are followed for about 64 weeks, with randomization to receive the study drugs or placebo under a controlled clinical setting. The trial uses a shared protocol framework (CWMM) to standardize eligibility and assessments across arms. Primary outcomes focus on weight loss and safety signals, with monitoring for cardiovascular and pancreatic adverse events. Locations include cardiovascular/hepatology research centers in Arizona, enrolling eligible adults according to the overarching protocol’s criteria.
Why it matters
Potential benefit: If successful, participants could experience meaningful weight loss and improved health markers related to obesity.
How similar studies have gone: Previous studies in similar weight-management programs using peptide-based therapies have shown promise, though this exact combination is being tested under a master protocol.
