Amryt Seeking Dispute Resolution on Filsuvez NDA
Amryt says it will file an FDA formal dispute resolution request over a complete response letter it received in February for its NDA for Filsuvez (oleogel-S10), indicated for treating cutaneous manifestations of dystrophic and junctional epidermolysis bullosa (EB). The rare genetic skin disease, Amryt says, is characterized by extremely fragile skin that blisters and tears from minor friction or trauma and for which there are no approved treatment options in the U.S.
The decision to file for dispute resolution follows a recent Type A meeting with FDA to discuss the complete response letter, which the company earlier said was seeking “additional confirmatory evidence of effectiveness for Oleogel-S10 in EB.”
Amryt says it continues to “believe that the strong body of data from the EASE trial, which was the largest ever Phase 3 trial conducted in EB, supports FDA approval of this vital therapy for EB patients with a high unmet medical need.” Earlier this week, Filsuvez was approved for treating EB in the European Union, the company says.
