FDA Hits Ipsen with Complete Response on Palovarotene
FDA has issued Ipsen Biopharmaceuticals a complete response letter on its NDA for palovarotene, an investigational treatment for reducing new abnormal bone formation (heterotopic ossification) in people living with fibrodysplasia ossificans progressiva (FOP). The ultra-rare disease causes permanent and continuous bone formation in soft and connective tissues like muscles, tendons and ligaments.
The letter reiterates a 10/22 request for additional information related to palovarotene’s clinical trial data, the company says. It expects to respond to the data request before 3/31.
In late October, FDA postponed a 10/31 Endocrinologic and Metabolic Drugs Advisory Committee meeting that was scheduled to review palovarotene. The company says the agency has not announced a new date for the panel meeting.
