U.S. FDA Advisory Committee Meeting on Palovarotene Rescheduled for June 28, 2023

Submit Your Written Testimony by June 14

Today, the U.S. Food & Drug Administration (FDA) announced that the Endocrinologic and Metabolic Drugs Advisory Committee has rescheduled their meeting to review Ipsen's new drug application (NDA) 215559 for palovarotene capsules for June 28, 2023.

A YouTube link for the June 28 meeting, and all meeting materials, will be made public on June 26. The IFOPA will provide this YouTube link and meeting materials once they are publicly posted by FDA. 

At the end of the meeting on June 28, the Advisory Committee will make a recommendation for or against approval to the FDA. It is important to note that the Committee’s recommendation is NOT the final decision. That decision will be announced later this year – by August 16 (also known as the PDUFA date).

The global FOP community has a valuable role to play in the FDA’s review of palovarotene. As part of their review, Advisory Committee members will have an opportunity to read letters submitted from the FOP community.

It is important to note that the IFOPA has not seen Ipsen’s data and is neutral in our support of the FDA’s approval of palovarotene. What we do believe is critically important is that the FDA and this Advisory Committee hear what it’s like to live with and care for someone with FOP. That is a story only you can tell and why the IFOPA is encouraging you to provide written testimony.
