Applied Therapeutics decides to hold on submission of AT-007 NDA

Applied Therapeutics provided a regulatory update on the AT-007 Galactosemia program. Following discussions with the FDA at the end of the year, the Company has decided to hold on submitting an NDA for AT-007 for treatment of Galactosemia pending additional discussions with the agency. Although the Galactosemia program had previously been discussed in the context of an NDA for Accelerated Approval based on reduction in galactitol, the FDA has now indicated that clinical outcomes data will likely be required for approval. The ongoing ACTION-Galactosemia Kids Phase 3 study is evaluating the impact of AT-007 treatment vs. placebo on clinical outcomes over time, including cognition, speech, behavior and motor skills. Clinical outcomes are assessed every 6 months by a firewalled committee. The first assessment will be completed in the first quarter of 2022, and then every 6 months thereafter until the study reaches statistical significance. "While disappointed by this change in direction by the FDA, we remain committed to bringing this important treatment to patients with Galactosemia," said Shoshana Shendelman, PhD, CEO, Founder and Chair of the Board of Applied Therapeutics. "We will continue to work with the FDA to determine the most expeditious path forward to regulatory approval and will provide an update on timing and plans accordingly."
