On February 15, 2024, Applied Therapeutics, Inc. announced positive interim 12-month results from the ongoing Phase 3 INSPIRE trial, in which the primary endpoints and several key secondary endpoints were achieved. The INSPIRE trial is a Phase 3 double-blind placebo-controlled registrational study evaluating the effect of once-daily (QD) oral govorestat (AT-007) in 56 patients aged 16-55 with SORD Deficiency in the US and Europe. Govorestat is a central nervous system penetrant Aldose Reductase Inhibitor, which blocks the conversion of glucose to sorbitol, and has previously been shown to reduce sorbitol levels in patients with SORD Deficiency.

The objective of this pre-specified, 12-month interim analysis was to evaluate early indicators of govorestat treatment effect in order to inform future regulatory discussions and support a potential New Drug Application (NDA) submission, due to the urgent need for treatment and absence of any other options for patients with SORDDeficiency. The 12-month interim analysis was comprised of a clinical efficacy primary endpoint based on correlation of sorbitol with composite clinical outcome measures, and a pharmacodynamic (PD) biomarker primary endpoint based on sorbitol reduction. The company believe the results from the 12-month interim analysis confirm the role of sorbitol as a key driver of disease severity and progression over time.

Clinical outcomes of the ongoing INSPIRE trial are expected to be assessed again at 24 months, where the 10-meter walk run test serves as the primary clinical efficacy endpoint. The Company plans to discuss a potential NDA submission with the U.S. Food and Drug Administration (FDA) based on the clinical data to date.
