Grace Therapeutics Announces First Quarter 2026 Financial Results,

Provides Business Update

NDA Supported by Data from Phase 3 STRIVE-ON Safety Trial, which Met Primary Endpoint and Provided Evidence of Clinical Benefit Compared to Orally Administered Nimodipine

Princeton, NJ, August 12, 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 aSAH patients, today announced the financial results and business highlights for the quarter ended June 30, 2025.

“During our first quarter of 2026 we continued to execute on our clinical and corporate goals, led by the submission of our NDA to the FDA for GTx-104 for the treatment of aSAH,” said Prashant Kohli, CEO of Grace Therapeutics. “Our NDA for GTx-104 was a significant milestone for the Company and built on more than a decade of painstaking research and innovation. Our NDA is supported by a robust data package including positive results from our STRIVE-ON trial, which provided evidence of improved clinical outcomes in aSAH patients treated with GTx-104 as well as potential medical and pharmacoeconomic benefits of GTx-104 in the treatment of aSAH. The standard of care for aSAH has not seen meaningful innovation in nearly 40 years, and we believe the STRIVE-ON trial results point to a very promising role for GTx-104 as a potential breakthrough for the care of aSAH patients. We are hopeful the FDA will accept our NDA for formal review, and look forward to continued engagement with the FDA during the review process.”

First Quarter 2026 Corporate Highlights

First Quarter 2026 Financial Results

The Company reported a net loss of $3.4 million, or $0.21 per share, for the three months ended June 30, 2025, an increase of $0.8 million from the net loss of $2.6 million, or $0.24 per share, for the three months ended June 30, 2024. The increase in net loss was primarily due to a $1.9 million difference in the change in fair value of derivative warrant liabilities and a $0.7 million decrease in income tax benefit, partially offset by a $1.8 million decrease in research and development expenses and a $0.1 million decrease in general and administrative expenses.

Total research and development expenses were approximately $0.9 million for the three months ended June 30, 2025, compared to $2.7 million for the three months ended June 30, 2024. The decrease of approximately $1.8 million was primarily due to a $1.9 million decrease in research activities mainly due to completion of our GTx-104 pivotal Phase 3 STRIVE-ON safety clinical trial, offset in part by a $0.1 million increase in professional fees in connection with the preparation and submission of our NDA to the FDA.

General and administrative expenses were approximately $2.1 million for the three months ended June 30, 2025, a decrease of $0.1 million from $2.2 million for the three months ended June 30, 2024. The decrease was primarily a result of decreased legal, accounting, tax, audit and other professional fees related to the continuance and domestication completed in October 2024, offset in part by an increase in salaries and benefits due to merit increases, increases in other general and administrative expenses primarily due to costs for GTx-104 commercial assessment, and an increase in stock-based compensation due to the issuance of new stock option awards.

Cash Runway

As of June 30, 2025, cash and cash equivalents were $20.0 million, a net decrease of approximately $2.1 million compared to cash and cash equivalents of $22.1 million at March 31, 2025.

The private placement the Company completed in February 2025 included common warrants exercisable for shares of common stock (or pre-funded warrants in lieu thereof) at an exercise price of $3.395 per share. Each common warrant is immediately exercisable and will expire on the earlier of (i) the 60th day after the date the FDA approves the NDA for GTx-104 and (ii) September 25, 2028. Potential gross proceeds from the exercise of the February 2025 common warrants are $15.0 million.

The private placement the Company completed in September 2023 included common warrants exercisable for shares of common stock at an exercise price of $3.003 per share. Each common warrant is immediately exercisable and will expire on the earlier of (i) the 60th day after the date of the acceptance by the FDA of the NDA for GTX-104 or (ii) five years from the date of issuance. Potential gross proceeds from the exercise of the September 2023 common warrants are $7.6 million.

About the STRIVE-ON Trial

The STRIVE-ON trial (NCT05995405) was a prospective, randomized open-label trial of GTx-104 compared with oral nimodipine in patients hospitalized with aSAH. 50 patients were administered GTx-104 and 52 patients received oral nimodipine. The primary endpoint was the number of patients with at least one episode of clinically significant hypotension reasonably considered to be caused by the drug, and additional secondary endpoints included safety, clinical, and pharmacoeconomic outcomes. The trial met its primary endpoint, with patients receiving GTx-104 observed to have a 19% reduction in at least one incidence of clinically significant hypotension compared to oral nimodipine (28% versus 35%). Other measures also favored or were comparable to GTx-104, including: 54% patients had relative dose intensity (RDI) of 95% or higher compared to only 8% on oral nimodipine, and 29% more patients had favorable functional outcomes at 90 days. In addition, there were fewer intensive care unit (ICU) readmissions, ICU days, and ventilator days for patients receiving GTx-104 versus oral nimodipine. Adverse events were comparable between the two arms and no new safety issues were identified with patients receiving GTx-104. All deaths in both arms of the trial were due to severity of the patient’s underlying disease. There were eight deaths on the GTx-104 arm compared to four deaths on the oral nimodipine arm. The survival status of one patient on the oral nimodipine arm was unknown. No deaths were determined to be related to GTx-104 or oral nimodipine.

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 aSAH, a relatively uncommon type of stroke that accounts for about 5% of all strokes and an estimated 42,500 U.S. hospital treated patients.

About the Grace Therapeutics Asset Portfolio

GTx-104 is a clinical stage, novel, injectable formulation of nimodipine being developed for IV 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 IV infusion.

GTx-104 provides a convenient IV 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.

GTx-102 is a novel, concentrated oral-mucosal spray of betamethasone intended to improve neurological symptoms of Ataxia-Telangiectasia (A-T), for which there are currently no FDA-approved therapies. GTx-102 is a stable, concentrated oral spray formulation comprised of the gluco-corticosteroid betamethasone that, together with other excipients can be sprayed conveniently over the tongue of the A-T patient and is rapidly absorbed. The Company received written responses to its End of Phase 1 meeting in GTx-102 where the FDA made recommendations on the path toward an NDA. The FDA provided guidance on the design of a single pivotal efficacy and safety trial, including the neurological assessment scale for the primary endpoint, that could, with appropriate confirmatory evidence, support an NDA. The further development of GTx-102 has been deprioritized in favor of focusing on development of GTx-104. It is also possible that the Company may license or sell GTx-102.

GTx-101 is a non-narcotic, topical bio-adhesive film-forming bupivacaine spray designed to ease the symptoms of patients suffering with postherpetic neuralgia (PHN). GTx-101 is administered via a metered-dose of bupivacaine spray and forms a thin bio-adhesive topical film on the surface of the patient’s skin, which enables a touch-free, non-greasy application. It also comes in convenient, portable 30 ml plastic bottles. Unlike oral gabapentin and lidocaine patches, which are used for the treatment of PHN, the Company believes that the biphasic delivery mechanism of GTx-101 has the potential for rapid onset of action and continuous pain relief for up to eight hours. No skin sensitivity was reported in a Phase 1 trial. The further development of GTx-101 has been deprioritized in favor of focusing on development of GTx-104. It is also possible that the Company may license or sell GTx-101.
