Enzyvant's Investigational Farber Disease Enzyme Replacement Therapy, RVT-801, Receives FDA Fast Track and Rare Pediatric Disease Designations

CAMBRIDGE, Mass. and BASEL, Switzerland, March 21, 2019 -- (Healthcare Sales & Marketing Network) -- Enzyvant, a biopharmaceutical company focused on developing and commercializing transformative therapies for patients with rare diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease and fast track designations for RVT-801, an investigational enzyme replacement therapy. RVT-801 has previously been granted orphan drug designations by the FDA and European Medicines Agency and is currently in preclinical development for Farber disease, a rare condition for which there are no approved treatments.

"These FDA designations underscore the significant need for a treatment for Farber disease and position RVT-801 to become available to patients as quickly as possible following a successful development program," said Rachelle Jacques, CEO of Enzyvant.

The FDA grants Rare Pediatric Disease designation for serious or life-threatening diseases that primarily affect children ages 18 years or younger and fewer than 200,000 individuals in the U.S. If a Biologics License Application for RVT-801 is approved, Enzyvant is eligible to receive a priority review voucher.

Fast Track is a process designed to facilitate the development and rapid review of drugs to treat serious conditions and fulfill unmet medical needs. The purpose of the designation is to deliver important new drugs to patients as rapidly as possible.

About Farber Disease

Farber disease is rare and thought to be significantly underdiagnosed, with patients often misdiagnosed with juvenile idiopathic arthritis. The disease is caused by mutations in the ASAH1 gene, resulting in deficiency of acid ceramidase, a critical lysosomal enzyme. This deficiency leads to the accumulation of ceramide within cells, which has pro-inflammatory and pro-apoptotic effects.

Farber disease patients typically present with the cardinal symptoms of joint contractures or arthritis, subcutaneous nodules and/or a weak or hoarse voice. More severe symptoms may also include impaired cognitive development due to brain involvement as well as impact on lungs, liver and bones (osteolysis). Disease onset is usually in early childhood but may occur later in life.

About RVT-801

RVT-801 is a recombinant form of human acid ceramidase (rhAC) being developed as a potential enzyme replacement therapy for acid ceramidase deficiency, manifesting as Farber disease. In a mouse model of Farber disease, RVT-801 was shown to be biologically active, reducing accumulation of ceramides and related inflammation in tissues.
