The NEJM publication adds credibility to setmelanotide's efficacy in acquired hypothalamic obesity, which may accelerate physician adoption. With FDA and EMA approvals already in place, the commercial focus is on market penetration. Monitor quarterly revenues for uptick in prescriptions.
Price Chart
Executive Summary
Rhythm Pharmaceuticals announced that the Phase 3 TRANSCEND trial results for setmelanotide (IMCIVREE) in acquired hypothalamic obesity were published in The New England Journal of Medicine. The data show a -19.8% placebo-adjusted BMI reduction with 80% of patients achieving ≥5% BMI reduction at 52 weeks. The publication reinforces the drug's efficacy after FDA approval (March 2026) and EMA recommendation, potentially supporting commercial adoption in a rare disease with no prior approved therapy.
