Applied Therapeutics Provides Regulatory Update on Govorestat for the Treatment of Classic Galactosemia

 Applied Therapeutics, Inc. (Nasdaq: APLT), a clinical-stage biopharmaceutical company developing a pipeline of novel drug candidates against validated molecular targets in indications of high unmet medical need, today announced an update on the ongoing New Drug Application (NDA) review of govorestat for the treatment of Classic Galactosemia. The Company recently completed its late-cycle review meeting with the United States Food and Drug Administration (FDA). The FDA communicated that an Advisory Committee meeting would no longer be required, which was previously tentatively scheduled for October 9, 2024. The FDA informed the Company that the Priority Review of the NDA is continuing as planned with alignment on post-marketing requirements expected in October 2024. The previously announced Prescription Drug User Fee Act (PDUFA) target action date remains on track for November 28, 2024.

“We are incredibly pleased by the ongoing collaborative dialogue with the FDA during the NDA review process, and we look forward to continuing to work together with the agency to bring the first potential treatment to Classic Galactosemia patients,” said Shoshana Shendelman, PhD, Founder and CEO of Applied Therapeutics. “Galactosemia is a progressive disease in urgent need of treatment, and the potential approval of govorestat will be transformative for the many patients and families living with this serious disease. Our commitment to the Classic Galactosemia community is further supported by our thoughtful commercial preparation, focused on establishing an effective patient access program, high physician awareness and strong payor engagement.”

About Galactosemia

Galactosemia is a rare genetic metabolic disease resulting in an inability to metabolize the simple sugar galactose. Galactose is found in foods, but is also produced endogenously by the body. 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). There are approximately 3,000 patients with Galactosemia in the US and 80 new births per year, and approximately 4,000 patients with Galactosemia in the EU and 120 new births per year. Newborn screening for Galactosemia is mandatory in the US and most EU countries, leading to rapid identification of affected patients.

About Govorestat (AT-007)

Govorestat is a central nervous system (CNS) penetrant Aldose Reductase Inhibitor (ARI) in development for the treatment of several rare neurological diseases, including Galactosemia, SORD Deficiency, and PMM2-CDG.

In a study in children with Galactosemia aged 2-17, 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. Galactitol is a toxic metabolite responsible for tissue damage and long-term complications in Galactosemia.

In the Phase 3 INSPIRE trial in patients with SORD Deficiency, an interim analysis at 12 months demonstrated a statistically significant reduction in blood sorbitol levels with govorestat treatment as compared to placebo, as well as a statistically significant correlation of sorbitol with change in clinical outcomes, such as 10-meter walk run test, dorsiflexion and 6-minute walk test. Govorestat also demonstrated highly statistically significant effects on the CMT Health Index (CMT-HI) patient reported outcome measure, with benefit of govorestat shown on lower limb function, mobility, fatigue, pain, sensory function, and upper limb function.  

Govorestat has received Orphan Medicinal Product Designation from the European Medicines Agency (EMA) for both Galactosemia and SORD Deficiency. Govorestat has also received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) for the treatment of Galactosemia, PMM2-CDG, and SORD Deficiency; Pediatric Rare Disease designation for Galactosemia and PMM2-CDG; and Fast Track designation for Galactosemia.
