  The European Commission granted Marketing Authorization for IMCIVREE in acquired HO on May 1, 2026. Additionally, the Japanese New Drug Application for setmelanotide in acquired HO is under review, with a decision anticipated in the second half of 2026.

• Pipeline Updates and EMANATE Trial Results

Rhythm Pharmaceuticals reported robust first-quarter 2026 product revenue growth, primarily driven by the successful U.S. launch of IMCIVREE for acquired hypothalamic obesity (HO). The company's lead drug also secured marketing authorization in Europe and is under regulatory review in Japan, signaling significant international expansion. While the net loss increased year-over-year, the strong commercial momentum and a stable cash position, projected to fund operations for at least 24 months, provide a positive outlook. Investors should monitor the continued rollout of IMCIVREE in new markets and upcoming pipeline data readouts, particularly for the next-generation MC4R agonists following mixed results from the EMANATE trial.
