Rhythm Pharmaceuticals Secures FDA Approval for Setmelanotide Expansion
Rhythm Pharmaceuticals' stock rose by 7.05% as it reached a 5-day high, following significant news regarding its lead asset, setmelanotide.
The company announced that setmelanotide received FDA approval for use in patients with acquired hypothalamic obesity, a rare obesity disorder, allowing treatment for patients aged 4 and older. This approval marks a significant advancement in the rare disease space, especially after the Phase 3 TRANSCEND trial demonstrated a 15.8% reduction in body mass index (BMI) among treated patients compared to a placebo group. This development solidifies Rhythm's leadership position in the rare obesity market and presents substantial financial growth potential.
The approval of setmelanotide as the first and only FDA-approved therapy for acquired hypothalamic obesity is expected to drive revenue growth for Rhythm Pharmaceuticals, as it prepares for market launch and addresses the urgent needs of approximately 10,000 patients in the U.S.
