Rhythm: PWS Signal, HO Speed Bump, And The Case For A Rare-Obesity Blockbuster
Rhythm Pharmaceuticals, Inc. remains a compelling rare-disease obesity platform, with a maintained Buy rating driven by progress in HO, PWS, and oral MC4R agonists. PWS Phase 2 data for IMCIVREE show early efficacy in BMI and hyperphagia reduction, though limited by small sample size and responder heterogeneity. RYTM's HO sNDA PDUFA was delayed to March 2026 for additional FDA analysis, but I remain optimistic on approval with some risk to pediatric labeling.
