Grace Therapeutics Announces Abstract Accepted for Presentation at Society of Vascular and Interventional Neurology Annual Meeting

PRINCETON, N.J., Nov. 11, 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 IV infusion to address significant unmet medical needs in aneurysmal subarachnoid hemorrhage (aSAH) patients, today announced that an abstract of the Company’s Pivotal Phase 3 STRIVE-ON Safety Trial of GTx-104 in aSAH (the STRIVE-ON trial–NCT05995405) has been accepted for presentation as a late breaking trial atthe Society of Vascular and Interventional Neurology (SVIN)annual meeting, to be held November 19-22, 2025 in Orlando, FL.

Thomas P Bleck, MD, Professor, Neurology (Neurocritical Care and Epilepsy/Clinical Neurophysiology) at Northwestern University Feinberg School of Medicine, will present results of the trial in an oral presentation held November 21, 2025.

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.

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.

Grace Therapeutics, Inc. (Grace Therapeutics or the Company) is a late-stage biopharma company with drug candidates addressing rare and orphan diseases. Grace Therapeutics’ novel drug delivery technologies have the potential to improve the performance of currently marketed drugs by achieving faster onset of action, enhanced efficacy, reduced side effects, and more convenient drug delivery. Grace Therapeutics’ lead clinical assets have each been granted Orphan Drug Designation by the FDA, which provides seven years of marketing exclusivity post-launch in the United States, and additional intellectual property protection with over 40 granted and pending patents. Grace Therapeutics’ lead clinical asset, GTx-104, is an I.V. infusion targeting aneurysmal Subarachnoid Hemorrhage (aSAH), a rare and life-threatening medical emergency in which bleeding occurs over the surface of the brain in the subarachnoid space between the brain and skull.
