Grace Therapeutics Announces 2025 Fiscal Year-End Results,

Provides Business Update

Held Type C meeting with FDA on Planned New Drug Application (NDA) Submission, Including Clinical, Non-clinical, and Chemistry, Manufacturing, and Control (CMC) Requirements

NDA On Track for Submission to FDA in First Half of Calendar 2025

NDA to be 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

Secured Private Placement Financing of $15 Million in Upfront Gross Proceeds with the Potential to Receive up to an Additional $15 Million in Potential Warrant Exercise Proceeds for an Aggregate of Up to Approximately $30 Million in Potential Total Gross Proceeds

Princeton, NJ, June 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 IV infusion to address significant unmet medical needs in aneurysmal subarachnoid hemorrhage (aSAH) patients, today announced the financial results and business highlights for the fiscal year ended March 31, 2025.

“During our 2025 fiscal year we made significant progress in both clinical and corporate goals, led by our announcement of positive topline data from our Phase 3 STRIVE-ON safety trial (the STRIVE-ON trial–NCT05995405) and alignment with the U.S. Food and Drug Administration (FDA) on our planned submission of an NDA for GTx-104 for the treatment of aSAH,” said Prashant Kohli, CEO of Grace Therapeutics. “We also secured financing of $15 million up front with the potential to receive up to an additional $15 million upon cash exercise of accompanying warrants issued in a private placement led by Nantahala Capital and ADAR1 Partners, LP along with other leading healthcare-focused investors. This investment will support pre-commercial planning, commercial team build out and product launch, if GTx-104 is approved.”

“Our focus now is to finalize our NDA submission for GTx-104, which we expect to complete by the end of June 2025. The standard of care for aSAH has not seen meaningful innovation in nearly 40 years. Data from our STRIVE-ON trial exceeded our expectations, and although STRIVE-ON was not designed or powered to demonstrate efficacy, the data provide support for improved clinical outcomes for patients treated with GTx-104 when compared to patients treated with orally administered nimodipine. Importantly, the data also provides both medical and pharmacoeconomic evidence of the potential benefit of GTx-104 in aSAH patients, which could help drive adoption of GTx-104 by neurocritical care physicians and hospital pharmacies. 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 should it be approved by the FDA,” concluded Mr. Kohli.

2025 Corporate Highlights

•

Held Type C meeting with the FDA to obtain feedback on the completed the STRIVE-ON trial and the planned NDA submission for GTx-104, including CMC requirements. Based on feedback from the FDA, the Company believes that the data and regulatory packages as currently structured will be sufficient for submission of an NDA.

•

Successfully concluded the STRIVE-ON trial, with GTx-104 meeting its primary endpoint; other measures also favored or were comparable to GTx-104.

•

NDA for GTx-104 is on track for submission to the FDA by the end of the first half of calendar year 2025.

•

Completed private placement financing of up to approximately $30.0 million in potential total gross proceeds, consisting of initial upfront funding of approximately $15.0 million and the potential to receive up to an additional approximately $15.0 million upon cash exercise of accompanying warrants at the election of the investors; the financing was led by Nantahala Capital and ADAR1 Partners, LP, and included participation from new and existing healthcare-focused institutional investors, including Stonepine Capital Management, among others. The net proceeds of the initial upfront funding were approximately $13.7 million, after deducting fees and expenses.

•

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.

Fiscal Year 2025 Financial Results

The Company reported a net loss of $9.6 million, or $0.79 loss per share, for the fiscal year ended March 31, 2025, a decrease of $3.3 million from the net loss of $12.9 million, or $1.35 per share, for the fiscal year ended March 31, 2024. The decrease in net loss was primarily due to an approximately $6.0 million difference in change in fair value of derivative warrant liabilities, a $1.5 million decrease in restructuring costs, and a $1.4 million increase in income tax benefits, partially offset by a $4.8 million increase in research and development expenses, net of government assistance, a $0.5 million increase in general and administrative expenses, and a $0.2 million decrease in interest and other income, net.

Total research and development expenses for the fiscal year ended March 31, 2025 were $9.5 million, compared to $4.7 million for the fiscal year ended March 31, 2024. The increase of $4.8 million was primarily due to the increase in research activities for the GTx-04 pivotal Phase 3 safety clinical trial.

General and administrative expenses were $7.2 million for the fiscal year ended March 31, 2025, an increase of $0.5 million from $6.7 million for the fiscal year ended March 31, 2024. The increase was primarily a result of increased legal, tax, accounting and other professional fees primarily related to the continuance and domestication completed in October 2024, increased salaries and benefits due to merit increases and hiring of a new employee, partially offset by a decrease in other expenses due primarily to adjustments for Canadian goods and services tax and a decrease in miscellaneous expenses as a result of restructuring in the prior year period. Stock-based compensation of $0.5 million the fiscal year ended March 31, 2025, decreased by $0.2 million compared to $0.7 million for the fiscal year ended March 31, 2024. The decrease was primarily due to fewer stock option awards granted during the fiscal year ended March 31, 2025.

At March 31, 2025, the Company had cash and cash equivalents of $22.1 million, a net decrease of $0.9 million compared to cash and cash equivalents of $23.0 million at March 31, 2024.

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 is $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 is $7.6 million.

While the Company believes that current cash and cash equivalents provide cash runway into the third quarter of calendar 2026, the runway could extend into the second quarter of calendar 2027 if all of the common warrants issued in connection with the Company’s February 2025 and September 2023 private placements are exercised at the election of the investors.

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 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 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 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.

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.
