Applied Therapeutics Seeks Pre-NDA Meeting for Govorestat
Applied Therapeutics plans to request a pre-NDA meeting with FDA on its govorestat (AT-007), a central nervous system penetrant aldose reductase inhibitor for treating patients with galactosemia, after reporting data from a recent Phase 3 study. Govorestat demonstrated “consistent long-term clinical outcomes benefit across a range of functional measures in the ACTION-Galactosemia Kids trial, confirming prior biomarker data,” the company says. Additionally, it says data showed that the drug “improved activities of daily living, behavior, cognition, fine motor skills, adaptive skills and tremor vs. placebo.”
The study was designed to evaluate the impact of govorestat treatment vs. placebo on clinical outcomes over time in 47 children ages two to 17 years. The primary endpoint, a composite score on the Global Statistical Test, was not met, Applied Therapeutics says, adding that systematic improvement over time was demonstrated and pre-specified sensitivity analyses were met. Govorestat provided a statistically significant benefit on tremor at 18 months (p=0.0428), as measured by the Archimedes Spiral Drawing Test, and adaptive skills as assessed by the BASC-3 Adaptive Skills Index (p=0.0265), it says.
Galactosemia is described by the company as a rare genetic metabolic disease resulting in an inability to metabolize the simple sugar galactose. “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.
