Grace Therapeutics Secures Approximately $4.0 Million through Common Warrant Exercises Following Acceptance of New Drug Application for GTx-104 for formal FDA Review

PRINCETON, N.J., Oct. 23, 2025 (GLOBE NEWSWIRE) -- Grace Therapeutics, Inc. (NASDAQ:GRCE) (Grace Therapeutics or the Company), a late-stage, biopharma company advancing GTx-104, a clinical-stage, novel, injectable formulation of nimodipine being developed for I.V. infusion to address significant unmet medical needs in aneurysmal subarachnoid hemorrhage (aSAH) patients, today announced it has secured approximately $4.0 million in additional funding through exercises of common warrants that were previously issued in a private placement that the Company closed in September 2023. The Company issued 1,345,464 new shares of common stock at an exercise price of $3.003 per share. The remaining 1,190,927 common warrants issued in the 2023 private placement have expired as the 60th day after the U.S. Food and Drug Administration's (FDA) acceptance for review of the Company's New Drug Application for GTx-104 has passed.

The FDA established a Prescription Drug User Fee Act (PDUFA) target date of April 23, 2026 for its review of the Company's NDA submission for GTx-104. The application seeks approval for GTx-104 for the treatment of patients with aSAH, and is supported by a comprehensive data package including positive data obtained from the Company's Phase 3 STRIVE-ON safety trial of GTx-104.

About aneurysmal Subarachnoid Hemorrhage (aSAH)

aSAH is bleeding over the surface of the brain in the subarachnoid space between the brain and the skull, which contains blood vessels that supply the brain. A primary cause of such bleeding is the rupture of an aneurysm in the brain. The result is a relatively uncommon type of stroke (aSAH) that accounts for about 5% of all strokes and an estimated 42,500 U.S. hospital treated patients.

About GTx-104

GTx-104 is a clinical stage, novel, injectable formulation of nimodipine being developed for I.V. infusion in aSAH patients to address significant unmet medical needs. The unique nanoparticle technology of GTx-104 facilitates aqueous formulation of insoluble nimodipine for a standard peripheral I.V. infusion.

GTx-104 provides a convenient I.V. delivery of nimodipine in the Intensive Care Unit, potentially eliminating the need for nasogastric tube administration in unconscious or dysphagic patients. Intravenous delivery of GTx-104 also has the potential to lower food effects, drug-to-drug interactions, and eliminate potential dosing errors. Further, GTx-104 has the potential to better manage hypotension in aSAH patients. GTx-104 has been administered in over 200 patients and healthy volunteers and was well tolerated with significantly lower inter- and intra-subject pharmacokinetic variability compared to oral nimodipine.
