(Nasdaq: RYTM), a biopharmaceutical company dedicated to addressing rare neuroendocrine diseases, has announced preliminary unaudited net product revenues for the fourth quarter (Q4) and full year (FY) 2025.

Upcoming Milestones and Strategic Initiatives
Rhythm Pharmaceuticals is actively preparing for significant upcoming events aimed at furthering the reach of IMCIVREE and expanding its portfolio:
- Launch of IMCIVREE for acquired hypothalamic obesity in the U.S. is pending FDA approval, with a PDUFA goal date set for March 20, 2026.
- Topline data from the 12-patient Japanese cohort of the Phase 3 trial in acquired hypothalamic obesity is expected in Q1 2026.
- Results from the Phase 3 EMANATE trial, evaluating setmelanotide in genetically caused MC4R pathway diseases, will also be reported in the first quarter of 2026.
