“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.”

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.

Such forward-looking statements involve known and unknown risks, uncertainties, and other factors that could cause the actual results of Grace Therapeutics to be materially different from historical results or from any future results expressed or implied by such forward-looking statements.

Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release. The forward-looking statements in this press release, including statements regarding the Company’s cash runway; future prospects of the Company’s GTx-104 drug candidate; the Company’s belief that the issues identified by the FDA in the CRL can be successfully addressed in the Company’s resubmission of the NDA for GTx-104; the Company’s planned approach to addressing the items cited in the CRL following its Type A meeting with the FDA and receipt of the official meeting minutes; the Company’s dual source manufacturing strategy, including remediation at its current contract manufacturer and technology transfer to a second, U.S.-based contract manufacturer; the timing and outcome of any FDA reinspection of the current contract manufacturer; the Company’s plans to complete the required non-clinical studies; and the Company’s plans to report progress against key milestones; GTx-104’s potential to bring enhanced treatment options to patients suffering from aSAH; the ability of GTx-104 to potentially eliminate the need for nasogastric tube administration in unconscious or dysphagic patients; the potential of GTx-104 to lower food effects, drug-to-drug interactions, and to eliminate potential dosing errors; the potential of GTx-104 to better manage hypotension in aSAH patients; and the Company’s intellectual property estate for GTx-104, are based upon Grace Therapeutics’ current expectations and involve assumptions that may never materialize or may prove to be incorrect. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of various risks and uncertainties, including, without limitation: (i) the timing and success of any regulatory resubmission of the NDA for GTx-104; (ii) the timing of any FDA reinspection of the Company’s current contract manufacturer, and that facility’s compliance status, which are determined by the FDA and outside the Company’s control, and the FDA’s position that it will not approve the NDA while the facility remains in an unacceptable compliance status; (iii) the ability of a second, U.S.-based contract manufacturer to generate the required stability and analytical data and to complete a product-specific pre-approval inspection; (iv) the need to complete additional non-clinical studies; (v) the requirement that any resubmission comprehensively address all items cited in the CRL and the risk of review delay; (vi) the Company’s potential need for additional capital, which may not be available on acceptable terms; (vii) changes to regulatory pathways; (viii) the Company’s ability to protect its intellectual property for GTx-104; and (ix) legislative, regulatory, political and economic developments. The foregoing list of important factors that could cause actual events to differ from expectations should not be construed as exhaustive and should be read in conjunction with statements that are included herein and elsewhere, including the risk factors detailed in the “Special Note Regarding Forward-Looking Statements,” “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2026 filed with the Securities and Exchange Commission (SEC) and its Quarterly Report on Form 10-Q for the quarter ended June 30, 2026, to be filed with the SEC and other documents that have been and will be filed by Grace Therapeutics from time to time with the SEC and Canadian securities regulators.
