The FDA has approved a topical gel containing birch triterpenes for the treatment of partial thickness wounds in patients 6 months and older with junctional epidermolysis bullosa (JEB) and dystrophic epidermolysis bullosa (DEB).
The gel is marketed under the name Filsuvez. It is the first approved treatment for wounds associated with JEB and the second for patients with DEB, following the approval of Vyjuvek (Krystal Biotech), a topical gene therapy gel, in May 2023.
First developed by Amryt Pharma and intended for home use, Filsuvez is now marketed by Chiesi Global Rare Diseases, which acquired Amryt in January 2023. The gel is applied topically to the wound at each dressing change.
The approval of Filsuvez is based on results from the Efficacy and Safety Study of Oleogel-S10 in Epidermolysis Bullosa, a randomized, placebo-controlled study of 223 people, the largest-ever phase 3 clinical trial for the treatment of EB, according to the Chiesi news release. The gel was well tolerated and met the primary endpoint with statistical significance, with 41.3% of patients achieving first complete target wound closure within 45 days (compared with 28.9% on placebo).
"I am so excited to say that this is another hurdle cleared and milestone achieved for the EB Community," Brett Kopelan, executive director at debra of America said in a blog post. "We are now on the road to being able to treat EB more effectively and to make the worst disease you've never heard of chronic, but livable, by making use of multiple therapeutic options in conjunction with each other."
