Priority Review Granted for Galactosemia NDA
FDA has accepted for priority review an Applied Therapeutics NDA for AT-007 (govorestat) for treating classic Galactosemia. Govorestat is described as a central nervous system penetrant aldose reductase inhibitor. The agency has set a user fee review action target date of 8/28.
Galactosemia is a rare genetic metabolic disease where patients are unable to metabolize the simple sugar galactose, according to the company. “When not metabolized properly, galactose is converted to the toxic metabolite, galactitol, which causes neurological complications, including deficiencies in speech, cognition, behavior, and motor skills, and also results in juvenile cataracts and ovarian insufficiency (in women),” it says.
Applied Therapeutics says the submission is based on clinical outcomes data from the Phase 3 ACTION-Galactosemia Kids study in children aged 2-17 with Galactosemia, the Phase 1/2 ACTION-Galactosemia study in adult patients with Galactosemia, and preclinical data. It adds that treatment with govorestat “demonstrated clinical benefit on activities of daily living, behavioral symptoms, cognition, fine motor skills and tremor. Govorestat also significantly reduced plasma galactitol levels in both adults and children with Galactosemia.”
