First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 2 times
Summary
This Phase 2b trial is testing whether two experimental drugs, macupatide and eloralintide, can help adults with obesity or overweight lose weight. About 400 participants will receive either one or both drugs or a placebo for 64 weeks. The study measures weight change and safety, excluding people with diabetes or certain heart conditions.
