In November 2025, the FDA extended the review period for IMCIVREE for patients with acquired hypothalamic obesity by three months, moving the PDUFA goal date to March 20, 2026, and the company also presented four datasets at ObesityWeek® 2025 and held a conference call for its Q3 2025 earnings.

In July 2025, the company announced positive topline results from its Phase 2 trial evaluating bivamelagon in acquired hypothalamic obesity, showing statistically significant and clinically meaningful BMI reductions, which led to a significant positive market reaction, and an upsized public offering of common stock raised approximately $189.2 million in net proceeds. In the past three months, Rhythm Pharmaceuticals insiders have sold more of the company's stock than they have bought, with sales totaling $3,436,340.00.

There is no explicit mention of significant demand seasonality for Rhythm Pharmaceuticals' products and services. Demand is likely driven by diagnosis and treatment initiation rather than seasonal factors.
