US FDA Prolongs Evaluation of Rhythm's Treatment for Obesity Linked to Brain Damage
FDA Review Extension: The FDA has extended the review period for Rhythm Pharmaceuticals' drug Imcivree, aimed at treating a rare form of obesity, by three months, moving the deadline from December 20, 2025, to March 20, 2026.
Company Response: CEO David Meeker expressed disappointment over the unexpected extension, noting that the FDA requested additional sensitivity analyses of efficacy data from a late-stage trial without any new safety or manufacturing data.
Trial Results: Imcivree showed significant weight reduction in patients with acquired hypothalamic obesity during a late-stage trial involving 120 participants, reinforcing confidence in the drug's efficacy.
Market Potential: Analysts believe that while approval for treating hypothalamic obesity is likely, the market uptake may be modest, with an estimated 10,000 patients in the U.S. affected by the condition.
