GRCE

PRINCETON, N.J., Aug. 13, 2026 (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 three months ended June 30, 2026. “We continue to make progress on the requirements for resubmission of our New Drug Application (NDA) for GTx-104,” said Prashant Kohli, Chief Executive Officer of Grace Therapeutics. “As previously disclosed, the U.S. Food and Drug Administration’s (FDA) Complete Response Letter (CRL) identified no clinical safety or efficacy deficiencies—the remaining items relate to chemistry, manufacturing and controls (CMC) and non-clinical data. We continue to address those items while advancing two manufacturing sites toward NDA resubmission. Our current contract manufacturer is remediating the FDA’s facility-level findings, while our second, U.S.-based contract manufacturer is advancing the technology transfer needed to begin the required 12-month stability program. NDA resubmission timing will reflect whichever manufacturing site reaches readiness first. The recent financing extends our expected cash runway through the end of calendar 2028, positioning us to execute on both manufacturing sites as we work toward NDA resubmission. We look forward to reporting our progress as we achieve these important milestones.” First Quarter 2027 and Recent Corporate Highlights Announced a $10 million private placement financing with new and existing institutional and accredited investors. The Company intends to use the net proceeds from the financing to support the manufacturing and regulatory work needed to advance GTx-104. Announced receipt of the FDA meeting minutes from a Type A Meeting held with the FDA to discuss the CRL issued on April 23, 2026. The minutes constitute the official record of the Type A meeting. As previously disclosed, the CRL did not identify any clinical safety or efficacy deficiencies and did not request additional clinical data. The items cited by the FDA relate to the current good manufacturing practice (cGMP) compliance status of the Company’s contract manufacturing organization — a facility-level matter, and not a GTx-104 product-specific quality finding — together with additional leachables data time points and excipient toxicology risk assessments. The Company intends to address each of the CRL items in its planned resubmission, including completing the required non-clinical studies. As part of its resubmission plan, the Company has initiated a dual-source manufacturing strategy for GTx-104 to mitigate potential remediation issues from the Company’s current contract manufacturer and provide flexibility, while continuing to address the remaining CMC and non-clinical items identified in the CRL. As such, a technology transfer to a second, U.S.-based contract manufacturer is already underway. The timing of NDA resubmission will reflect the manufacturing pathway that reaches readiness first: either (i) the U.S.-based facility, which would require completion of a full CMC package supported by 12 months of stability data following the technology transfer; or (ii) the Company’s current contract manufacturer, if it successfully remediates its FDA compliance issues and is able to support the NDA sooner. First Quarter 2027 Financial Results The Company reported a net loss of $15.8 million, or $0.91 loss per share for the three months ended June 30, 2026, compared to $3.4 million, or $0.21 loss per share, for the quarter ended June 30, 2025. The increase in net loss was primarily due to a $13.5 million impairment of IPR&D related to GTx-101 and GTx-102 as further described below. This increase was partially offset by a favorable $0.5 million difference in the change in fair value of derivative warrant liabilities and a $0.4 million decrease in general and administrative expenses. Cash used in operations was approximately $3.2 million. Consistent with the Company’s previously announced 2023 decision to deprioritize GTx-101 and GTx-102 in favor of GTx-104, and following reevaluation of strategic priorities during the first quarter of 2027, the Company recorded a full impairment of the remaining IPR&D carrying value associated with GTx-101 and GTx-102. The Company also evaluated the carrying value of its IPR&D related to GTx-104 following the receipt of the CRL. Based on the assessment, the Company determined that the fair value exceeds the carrying amount, and no impairment charge was required for the quarter ended June 30, 2026. Total research and development expenses for the three months ended June 30, 2026, were $0.7 million, compared to $1.0 million three months ended June 30, 2025. The decrease was primarily due to a $0.3 million decrease in research activities mainly due to the completion of our GTx-104 pivotal Phase 3 STRIVE-ON safety clinical trial and submission of our NDA to the FDA during the prior period, whereas the current period research activities were only focused on addressing certain items identified in the CRL from the FDA. General and administrative expenses were $1.7 million for the three months ended June 30, 2026, a decrease of $0.4 million from $2.1 million for the three months ended June 30, 2025. The decrease was primarily a result of a decrease in pre-commercial planning activities for GTx-104 offset in part by increased legal costs related to the Type A meeting with the FDA, and a decrease in stock-based compensation due to the issuance of new stock option awards for the three months ended June 30, 2025, with no such issuance occurring for the three months ended June 30, 2026. Cash Runway As of August 11, 2026, cash and cash equivalents were $22.2 million, The Company plans to use its current cash towards resolving the items cited in the CRL, working capital and other general corporate purposes. The Company believes its existing cash and cash equivalents will be sufficient to sustain planned operations, including the activities to address the items cited in the CRL, through the end of calendar 2028. 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 GTx-104 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 nimodipine oral capsules. About Grace Therapeutics 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 asset, GTx-104, is an IV 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. GTx-104 has been granted Orphan Drug Designation by the FDA, which provides seven years of marketing exclusivity post-launch in the United States if certain conditions are met at NDA approval, and additional intellectual property protection with 52 granted and pending patents.

Type A Meeting Scheduled with FDA to Potentially Clarify Path to GTx-104 NDA Resubmission Phase 3 STRIVE-ON Safety Trial Data Presented at Multiple Medical Conferences Company Continues Disciplined Pre-Commercial Planning in Anticipation of Potential FDA Approval of NDAResubmission for GTx-104 for the Treatment of Patients with aSAH PRINCETON, N.J., June 18, 2026 (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 fiscal year ended March 31, 2026. “Since receipt of the U.S. Food and Drug Administration’s (FDA) Complete Response Letter (CRL) in April 2026, we have been working diligently on addressing the cited items, and we look forward to a constructive discussion with the FDA as we continue to prepare our resubmission,” said Prashant Kohli, CEO of Grace Therapeutics. “FDA approval of our New Drug Application (NDA) for GTx-104 for the treatment of aSAH would represent the first meaningful innovation in the standard of care for these patients in more than 40 years. As evidenced by the response among researchers, practitioners and industry leaders to the presentation of our Phase 3 STRIVE-ON trial results at major medical conferences throughout the fiscal year, we believe there is a significant desire in the marketplace for an intravenously administered nimodipine. We are confident in the robust data package supporting our NDA, and that the issues identified by the FDA can be successfully addressed in our resubmission.” Fiscal 2026 and Recent Corporate Highlights On April 23, 2026, the FDA issued a CRL for the Company’s NDA for GTx-104 for the treatment of patients with aSAH. In the CRL, the FDA referenced certain items in the Chemistry, Manufacturing, and Controls (CMC) and Non-Clinical sections of the application, which Grace believes it can address in a resubmission of its NDA. The cited items are related to additional leachable data time points for commercial product, non-clinical product toxicology risk assessments, and current Good Manufacturing Practices (cGMP) deficiencies with our contract manufacturing organization. No clinical deficiencies were identified. A Type A meeting with the FDA has been scheduled to potentially clarify the path forward and determine the appropriate next steps. The Company expects to provide a regulatory update after the receipt of official meeting minutes. Fiscal Year 2026 Financial Results The Company reported a net loss of $7.8 million, or $0.47 loss per share for the fiscal year ended March 31, 2026, representing a $1.8 million decrease in net loss from $9.6 million, or $0.79 loss per share, for the fiscal year ended March 31, 2025. Total research and development expenses were $2.4 million for the fiscal year ended March 31, 2026, compared with $9.5 million, for the fiscal year ended March 31, 2025. The decrease of $7.1 million was primarily due to the decrease in research activities of $7.5 million driven by the close-out of the GTx-104 pivotal Phase 3 safety clinical trial during the first calendar quarter of 2026, offset by a $0.4 million increase in external consulting and data management costs incurred in support of the NDA of GTx-104, which was submitted to the FDA in June 2025. General and administrative expenses were $8.7 million for the fiscal year ended March 31, 2026, compared to $7.2 million for the fiscal year ended March 31, 2025. The increase of $1.5 million was primarily driven by $0.8 million in non-recurring legal and due diligence costs incurred in connection with strategic initiatives evaluated during the period, as well as increased professional fees and other general and administrative costs of $0.9 million primarily related to pre-commercial planning for GTx-104, offset in part by a decrease in salaries and benefits of $0.2 million primarily a result of decreased headcount. Cash Runway At March 31, 2026, the Company had cash and cash equivalents of $17.0 million, a net decrease of $5.1 million compared to cash and cash equivalents of $22.1 million at March 31, 2025. The Company plans to use its current cash towards resolving the items cited in the FDA’s Complete Response Letter, working capital and other general corporate purposes. The Company believes its existing cash and cash equivalents will be sufficient to sustain planned operations through at least 12 months from the date of this press release. About the STRIVE-ON Trial The STRIVE-ON trial (NCT05995405) was a prospective, randomized open-label trial of GTx-104 compared with nimodipine oral capsules (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 GTx-104 or were comparable between the GTx-104 arm and the oral nimodipine arm, including: 54% patients on GTx-104 had relative dose intensity (RDI) of 95% or higher compared to only 8% on oral nimodipine, and 29% more patients on GTx-104 than on oral nimodipine 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 in the GTx-104 arm compared to four deaths in the oral nimodipine arm. The survival status of one patient in the oral nimodipine arm was unknown. No deaths were determined to be related to GTx-104 or oral nimodipine.

FDA Established April 23, 2026 as PDUFA Target Date for Review of Submission Seeking Approval for GTx-104 in the Treatment of Patients with aneurysmal Subarachnoid Hemorrhage (aSAH) Phase 3 STRIVE-ON Safety Trial Data Presented at 2025 Society of Vascular and Interventional Neurology Annual Meeting Company Continues Pre-Commercial Planning in Anticipation of Potential FDA Approval of NDA Submission for GTx-104 for the Treatment of Patients with aSAH PRINCETON, N.J., Feb. 12, 2026 (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 December 31, 2025. “During our third quarter of fiscal 2026 we continued to execute on our clinical and corporate goals, led by our pre-commercial planning in anticipation of potential FDA approval of our New Drug Application (NDA) for GTx-104 for the treatment of aSAH,” said Prashant Kohli, CEO of Grace Therapeutics. “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. We were pleased to see these data highlighted in a late breaking presentation at the Society of Vascular and Interventional Neurology annual meeting in November 2025. Our STRIVE-ON trial results continue to be well received by researchers, practitioners and industry leaders. We believe that if our NDA for GTx-104 is approved by the FDA, our strong U.S. and international patent estate will help to maximize the long-term market value of GTx-104 and correspondingly deliver value for our shareholders. The standard of care for aSAH has not seen meaningful innovation in nearly 40 years, and we believe that if GTx-104 is approved, our STRIVE-ON trial results point to a very promising role for GTx-104 in the treatment of these patients. We look forward to continuing to engage with the FDA during their review as they work toward the PDUFA target date of April 23, 2026.” Third Quarter 2026 and Recent Corporate Highlights During our third fiscal quarter we provided grant support for the development of a Continuing Medical Education (CME) program for healthcare professionals in medical specialties related to the care of aSAH patients. Content for the CME program was independently developed by leading providers of CME content and is intended to educate Health Care Professionals on the current challenges in treating aSAH patients. On November 21, 2025, the Company presented data from its pivotal Phase 3 STRIVE-ON Safety Trial of GTx-104 in aSAH as a late breaking trial at the Society of Vascular and Interventional Neurology annual meeting. The presentation titled Safety and Tolerability of GTX-104 (Nimodipine Injection for IV Infusion) Compared with Oral Nimodipine in Patients with Aneurysmal Subarachnoid Hemorrhage: a Prospective, Randomized Trial, was presented by Thomas P. Bleck, MD, Professor, Neurology (Neurocritical Care and Epilepsy/Clinical Neurophysiology) at Northwestern University Feinberg School of Medicine. On October 23, 2025, the Company announced that it had 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 expired on October 21, 2025. Third Quarter 2026 Financial Results The Company reported a net loss of approximately $2.3 million, or $0.14 per share, for the three months ended December 31, 2025, a decrease of approximately $1.8 million from the net loss of $4.2 million, or $0.36 per share, for the three months ended December 31, 2024. The decrease in net loss was primarily due to a $1.7 million decrease in research and development expenses and a $1.1 million decrease in the change of fair value of derivative warrant liabilities, partially offset by increases in general administrative expenses of $0.5 million and a decrease in income tax benefit of $0.6 million. Total research and development expenses for the three months ended December 31, 2025, were $0.5 million, compared to $2.2 million for the three months ended December 31, 2024. The decrease of $1.7 million was primarily due to a $1.8 million decrease in research activities mainly due to completion of our GTx-104 pivotal Phase 3 STRIVE-ON safety clinical trial, partially offset by a $0.1 million increase in salaries and benefits due to merit increases. General and administrative expenses were $2.0 million for the three months ended December 31, 2025, an increase of $0.5 million from $1.5 million for the three months ended December 31, 2024. The increase was primarily a result of an increase in professional fees and other general and administrative expenses primarily due to costs for GTx-104 pre-commercial planning. Cash Runway As of December 31, 2025, cash and cash equivalents were $18.7 million, a net decrease of $3.4 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 Company plans to use its current cash and cash equivalents to further the regulatory review process for GTx-104, pre-commercial planning, commercial team buildout, and product launch if GTx-104 is approved, working capital and other general corporate purposes. The Company believes its existing cash and cash equivalents will be sufficient to sustain planned operations through at least 12 months from the date of this press release. 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 GTx-104 or were comparable between GTx-104 and oral nimodipine, including: 54% patients on GTx-104 had relative dose intensity (RDI) of 95% or higher compared to only 8% on oral nimodipine, and 29% more patients on GTx-104 than on oral nimodipine 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. About Grace Therapeutics 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.

Announced U.S. Food and Drug Administration (FDA) Acceptance for Review of New Drug Application (NDA) for GTx-104 FDA Established April 23, 2026 as PDUFA Target Date for Review of Submission Seeking Approval for GTx-104 in the Treatment of Patients with aneurysmal Subarachnoid Hemorrhage (aSAH) Phase 3 STRIVE-ON Safety Trial Data Presented at 2025 Neurocritical Care Annual Meeting Granted Sixth U.S. Patent Covering IV Dosing Regimen for GTx-104 PRINCETON, N.J., Nov. 13, 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 September 30, 2025. “During our second quarter of 2026 we continued to execute on our clinical and corporate goals, led by FDA acceptance for review of our NDA for GTx-104 for the treatment of aSAH,” said Prashant Kohli, CEO of Grace Therapeutics. “Acceptance of our NDA for review is another significant milestone for the Company and further demonstrates our ability to execute as we continue to advance this important innovation for aSAH patients. 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. We were pleased to see these data highlighted in a presentation at the Neurocritical Care annual meeting, where the results were well received by the conference attendees. Also this quarter, the U.S. Patent and Trademark Office issued a new method of use patent covering the dosing regimen for IV administration of nimodipine used in our STRIVE-ON trial for GTx-104. This new patent coverage on the dosing regimen should be included in the label for GTx-104 if it is approved by the FDA, adding a new layer and extending the duration of our intellectual property protections. We believe that if our NDA for GTx-104 is approved by the FDA, our strong U.S. and international patent estate will help to maximize the long-term market value of GTx-104 and correspondingly deliver value for our shareholders.” The standard of care for aSAH has not seen meaningful innovation in nearly 40 years, and we believe that if GTx-104 is approved, our STRIVE-ON trial results point to a very promising role for GTx-104 in the treatment of these patients. We look forward to continuing to engage with the FDA during their review as they work toward the PDUFA target date of April 23, 2026.” Second Quarter 2026 Corporate Highlights On August 22, 2025, the FDA accepted the Company’s NDA for GTx-104 for formal review, establishing April 23, 2026 as its PDUFA target date. The application is supported by a comprehensive data package, including positive data obtained from the Company’s Phase 3 STRIVE-ON safety trial of GTx-104, whereby it met its primary endpoint and provided evidence of clinical benefit when compared to orally administered nimodipine. These data were presented at the Neurocritical Care annual meeting, held in Montreal, Quebec, Canada in September 2025. On September 16, 2025, U.S. Patent and Trademark Office issued a U.S. Patent No. 12,414,943, titled “Nimodipine Parenteral Administration”. The new method of use patent covers the dosing regimen for IV administration of nimodipine used in the Phase 3 STRIVE-ON safety trial for GTx-104. Grace Therapeutics has established a multi-layered intellectual property estate for GTx-104, including five patents on the composition of the Company’s formulation of nimodipine, which provide patent protection to 2037. The new patent on the IV dosing regimen for GTx-104 strengthens the Company’s intellectual property position and extends protection to 2043. Grace has also been granted Orphan Drug Designation from the FDA, which provides GTx-104 with seven years of marketing exclusivity in United States upon FDA approval of the Company’s NDA. On October 23, 2025, the Company announced that 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 expired as the 60th day after the FDA’s acceptance for review of the Company’s NDA for GTx-104 has passed. The Company estimates that its cash and cash equivalents were approximately $20.0 million as of October 31, 2025. Second Quarter 2026 Financial Results The Company reported a net loss of $0.9 million, or $0.06 per share, for the three months ended September 30, 2025, a decrease of $2.5 million from a net loss of $3.4 million, or $0.30 per share, for the three months ended September 30, 2024. The decrease in net loss was primarily due to a $2.4 million decrease in research and development expenses and a $1.1 million difference in the change in fair value of derivative warrant liabilities, partially offset by a $0.9 million decrease in income tax benefit and a $0.1 million increase in general and administrative expenses. Total research and development expenses for the three months ended September 30, 2025, were $0.6 million, compared to $3.0 million for the three months ended September 30, 2024. The decrease of $2.4 million was primarily due to a $2.5 million decrease in research activities mainly due to completion of our GTx-104 pivotal Phase 3 STRIVE-ON safety trial, partially offset by an increase in salaries and benefits due to merit increases. General and administrative expenses were $2.0 million for the three months ended September 30, 2025, an increase of $0.1 million from $1.9 million for the three months ended September 30, 2024. The increase was primarily a result of an increase in other general and administrative expenses primarily due to costs for GTx-104 pre-commercial planning. Cash Runway As of September 30, 2025, cash and cash equivalents were $16.9 million, a net decrease of $5.2 million compared to cash and cash equivalents of $22.1 million at March 31, 2025. In October 2025, the Company received $4.0 million in gross proceeds from exercises of common warrants that were previously issued in a private placement in September 2023. 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. While the Company believes that current cash and cash equivalents provide cash runway through at least the next twelve months, 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 private placement 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.

Submission of New Drug Application (NDA) to U.S. Food and Drug Administration (FDA) for GTx-104 Seeking Approval of GTx-104 in the Treatment of Patients with aneurysmal Subarachnoid Hemorrhage (aSAH) 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, N.J., Aug. 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 Submission to the FDA of the Company’s NDA for GTx-104. The application included a comprehensive data package, including positive data obtained from the Company’s Phase 3 STRIVE-ON safety trial of GTx-104, whereby it met its primary endpoint and provided evidence of clinical benefit when compared to orally administered nimodipine. Submission of the NDA has the potential to trigger the exercise of up to $7.6 million in warrants issued as part of a private placement the Company completed in September 2023. Under the terms of the September 2023 private placement, each warrant is exercisable for one share of common stock at an exercise price of $3.003 per share. These warrants are immediately exercisable and will expire on the earlier of (i) the 60th day after the date of the acceptance by the FDA of an NDA for the Company's product candidate GTx-104 or (ii) September 25, 2028. The FDA typically has a 60-day period to determine if the Company’s NDA is complete and acceptable for filing. Grace has obtained Orphan Drug Designation from the FDA for GTx-104, which generally provides seven years of marketing exclusivity in United States upon FDA approval of the NDA. Additionally, the Company believes that its U.S. and international patent estate will provide additional marketing exclusivity for GTx-104. 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. While the Company believes that current cash and cash equivalents provide cash runway through at least the next twelve months, 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 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. About Grace Therapeutics Grace Therapeutics, Inc.

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, N.J., 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.
