Grace Therapeutics, Inc. (formerly known as Acasti Pharma Inc.) (“Acasti Delaware” or “the Company”), is a Delaware corporation that, as further described below, previously existed under the laws of the Province of Québec, Canada (“Acasti Québec”), before changing its jurisdiction on October 1, 2024 to the Province of British Columbia, Canada (“Acasti British Columbia”). On October 7, 2024, Acasti British Columbia changed its jurisdiction to the State of Delaware. Effective October 28, 2024, the Company changed its corporate name to Grace Therapeutics, Inc.

On October 1, 2024, Acasti Québec changed its jurisdiction of incorporation from the Province of Québec in Canada to the Province of British Columbia in Canada pursuant to a “continuance” effected in accordance with Chapter XII of the Business Corporations Act (Québec) (the “Continuance”). Subsequently on October 7, 2024 (the “Effective Date”), Acasti British Columbia changed its jurisdiction of incorporation from the Province of British Columbia in Canada to the State of Delaware in the United States of America pursuant to a “continuance” effected in accordance with Section 308 of the Business Corporations Act (British Columbia) and a “domestication” (the “Domestication”) under Section 388 of the General Corporation Law of the State of Delaware. Both the Continuance and the Domestication were approved by the Company’s shareholders at the Company’s Annual and Special Meeting of Shareholders held on September 30, 2024.

Prior to the Continuance and Domestication, the Company’s Class A common shares, without par value per share (“Common Shares”), were listed on The Nasdaq Stock Market LLC (“Nasdaq”) under the symbol “ACST.” Upon the effectiveness of the Continuance, each outstanding Class A common share of Acasti Québec at the time of the Continuance remained issued and outstanding as a common share, without par value per share, of Acasti British Columbia. Upon effectiveness of the Domestication, each outstanding common share of Acasti British Columbia at the time of the Domestication automatically became one outstanding share of common stock, par value $0.0001 per share, of Acasti Delaware (“Common Stock”). The Common Stock continues to be listed for trading on Nasdaq and in connection with its corporate name change to Grace Therapeutics, Inc., commenced trading under the symbol “GRCE” on October 28, 2024.

The Continuance and Domestication has been accounted for as an exchange of equity interest among entities under common control resulting in a change in reporting entity, and has been retroactively reflected in the accompanying consolidated financial statements and notes thereto. All assets and liabilities of Acasti British Columbia were deemed assumed by the Company at the Effective Date, resulting in the retention of the historical basis of accounting as if they had always been combined for accounting and financial reporting purposes. Any excess resulting from the automatic conversion of each outstanding Common Share of Acasti British Columbia into one outstanding share of Common Stock of Acasti Delaware, is presented as Additional Paid-in Capital in the equity section of the accompanying consolidated financial statements and notes thereto. All per share amounts for all periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect the effect of the change in par value.

In May 2023, the Company implemented a strategic realignment plan to enhance shareholder value that resulted in the Company engaging a new management team, streamlining its research and development activities, and greatly reducing its workforce. Following the realignment, the Company is a smaller, more focused organization, based in the United States, and concentrated on its development of its lead product candidate GTx-104. Further development of GTx-102 and GTx-101 will occur at such a time when the Company is able to secure additional funding or enters into strategic partnerships for license or sale with third parties.

The Company plans to use its current cash 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 issuance date of these consolidated financial statements included in the Company’s Annual Report on Form 10-K.

The Company will require additional capital to fund its daily operating needs. The Company does not expect to generate revenue from product sales unless and until it successfully completes drug development and obtains regulatory approval, which is subject to significant uncertainty. To date, the Company has financed its operations primarily through public offerings and private placements of its common equity, warrants and convertible debt and the proceeds from research tax credits. Until such time that the Company can generate significant revenue from drug product sales, if ever, it will require additional financing, which is expected to be sourced from a combination of public or private equity or debt financing or other non-dilutive sources, which may include fees, milestone payments and royalties from collaborations with third parties. Arrangements with collaborators or others may require the Company to relinquish certain rights related to its technologies or drug product candidates. Adequate additional financing may not be available to the Company on acceptable terms, or at all. The Company’s inability to raise capital as and when needed could have a negative impact on its financial condition and its ability to pursue its business strategy. The Company plans to raise additional capital in order to maintain adequate liquidity. Negative results from studies or trials, if any, the timing and ability to receive U.S. Food and Drug Administration (“FDA”) approval for marketing our drug candidates or depressed prices of the Company’s stock could impact the Company’s ability to raise additional financing. Raising additional equity capital is subject to market conditions that are not within the Company’s control. If the Company is unable to raise additional funds, the Company may not be able to realize its assets and discharge its liabilities in the normal course of business.

The Company remains subject to risks similar to other development stage companies in the biopharmaceutical industry, including compliance with government regulations, protection of proprietary technology, dependence on third-party contractors and consultants and potential product liability, among others. Please refer to the risk factors included in Part 1, “Item 1A – Risk Factors” of this Annual Report on Form 10-K.

Nature of Operations [Abstract]
Nature of operations	1. Nature of Operations General Grace Therapeutics, Inc. (formerly known as Acasti Pharma Inc.) (“Acasti Delaware” or “the Company”), is a Delaware corporation that, as further described below, previously existed under the laws of the Province of Québec, Canada (“Acasti Québec”), before changing its jurisdiction on October 1, 2024 to the Province of British Columbia, Canada (“Acasti British Columbia”). On October 7, 2024, Acasti British Columbia changed its jurisdiction to the State of Delaware. Effective October 28, 2024, the Company changed its corporate name to Grace Therapeutics, Inc. Continuance and Domestication On October 1, 2024, Acasti Québec changed its jurisdiction of incorporation from the Province of Québec in Canada to the Province of British Columbia in Canada pursuant to a “continuance” effected in accordance with Chapter XII of the Business Corporations Act (Québec) (the “Continuance”). Subsequently on October 7, 2024 (the “Effective Date”), Acasti British Columbia changed its jurisdiction of incorporation from the Province of British Columbia in Canada to the State of Delaware in the United States of America pursuant to a “continuance” effected in accordance with Section 308 of the Business Corporations Act (British Columbia) and a “domestication” (the “Domestication”) under Section 388 of the General Corporation Law of the State of Delaware. Both the Continuance and the Domestication were approved by the Company’s shareholders at the Company’s Annual and Special Meeting of Shareholders held on September 30, 2024. Prior to the Continuance and Domestication, the Company’s Class A common shares, without par value per share (“Common Shares”), were listed on The Nasdaq Stock Market LLC (“Nasdaq”) under the symbol “ACST.” Upon the effectiveness of the Continuance, each outstanding Class A common share of Acasti Québec at the time of the Continuance remained issued and outstanding as a common share, without par value per share, of Acasti British Columbia. Upon effectiveness of the Domestication, each outstanding common share of Acasti British Columbia at the time of the Domestication automatically became one outstanding share of common stock, par value $0.0001 per share, of Acasti Delaware (“Common Stock”). The Common Stock continues to be listed for trading on Nasdaq and in connection with its corporate name change to Grace Therapeutics, Inc., commenced trading under the symbol “GRCE” on October 28, 2024. The Continuance and Domestication has been accounted for as an exchange of equity interest among entities under common control resulting in a change in reporting entity, and has been retroactively reflected in the accompanying consolidated financial statements and notes thereto. All assets and liabilities of Acasti British Columbia were deemed assumed by the Company at the Effective Date, resulting in the retention of the historical basis of accounting as if they had always been combined for accounting and financial reporting purposes. Any excess resulting from the automatic conversion of each outstanding Common Share of Acasti British Columbia into one outstanding share of Common Stock of Acasti Delaware, is presented as Additional Paid-in Capital in the equity section of the accompanying consolidated financial statements and notes thereto. All per share amounts for all periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect the effect of the change in par value. Liquidity and Financial Condition The Company has incurred operating losses and negative cash flows from operations in each period since its inception. The Company expects to incur significant expenses and continued operating losses for the foreseeable future. In May 2023, the Company implemented a strategic realignment plan to enhance shareholder value that resulted in the Company engaging a new management team, streamlining its research and development activities, and greatly reducing its workforce. Following the realignment, the Company is a smaller, more focused organization, based in the United States, and concentrated on its development of its lead product candidate GTx-104. Further development of GTx-102 and GTx-101 will occur at such a time when the Company is able to secure additional funding or enters into strategic partnerships for license or sale with third parties. In February 2025, the Company completed a private placement of Company securities with certain institutional and accredited investors. Net proceeds to the Company were $13,705. Refer to Note 8, 2025 Private Placement, for additional information. The Company plans to use its current cash 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 issuance date of these consolidated financial statements included in the Company’s Annual Report on Form 10-K. The Company will require additional capital to fund its daily operating needs. The Company does not expect to generate revenue from product sales unless and until it successfully completes drug development and obtains regulatory approval, which is subject to significant uncertainty. To date, the Company has financed its operations primarily through public offerings and private placements of its common equity, warrants and convertible debt and the proceeds from research tax credits. Until such time that the Company can generate significant revenue from drug product sales, if ever, it will require additional financing, which is expected to be sourced from a combination of public or private equity or debt financing or other non-dilutive sources, which may include fees, milestone payments and royalties from collaborations with third parties.
