Is this trial a fit for you?
✓Likely a good fit
Adults with BMI ≥25 who previously lost ≥10% of body weight on a weekly GLP-1 RA, with stable weight and GI tolerability, and who are willing to participate.
✕Probably not a fit
Patients who do not respond well to the switch or experience adverse effects may not benefit.

What this trial studies
This Phase 3 trial examines the efficacy, safety, and tolerability of switching patients from a weekly GLP-1 receptor agonist to maridebart cafraglutide. Eligible adults have BMI ≥25 and achieved ≥10% weight loss on a GLP-1 RA, with stable weight and GI tolerance, and are willing to follow trial procedures. The study will monitor weight-related outcomes and adverse events to determine if the switch provides continued or improved weight management. Participants will be recruited at multiple sites and followed for the trial duration under close medical supervision.
Why it matters
Potential benefit: If successful, switching to maridebart cafraglutide could help sustain weight loss and improve tolerability for some patients.
How similar studies have gone: Prior research with similar GLP-1RA switching approaches has shown varying tolerability; this study contributes new data on maridebart cafraglutide.
