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. Approximately 70% of aSAH patients experience death or dependence, and more than 30% die within one month of hemorrhage. Approximately 50,000 patients in the United States are affected by aSAH per year, based on market research. Outside of the United States, annual cases of aSAH are estimated at approximately 60,000 in the European Union, and approximately 150,000 in China. About the Grace Therapeutics Asset Portfolio GTx-104 is a clinical stage, novel, injectable formulation of nimodipine being developed for intravenous (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 150 healthy volunteers and was well tolerated with significantly lower inter- and intra-subject pharmacokinetic variability compared to oral nimodipine. The addressable market in the United States for GTx-104 is estimated to be about $300 million, based on market research. 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 further development of GTx-102 has been deprioritized in favor of our focus on development of GTx-104. It is also possible that we may license or sell our GTx-102 drug candidate. 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, we believe 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 our focus on development of GTx-104. It is also possible that we may license or sell our GTx-101 drug candidate.

Name Change Reflects Extensive Scientific and Corporate Brand Equity Previously Established under Grace Therapeutics Grace Therapeutics will begin trading on Nasdaq under the trading symbol "GRCE" effective October 28, 2024 Virtual Key Opinion Leader Event to be held on November 20th PRINCETON, N.J., Oct. 25, 2024 (GLOBE NEWSWIRE) -- Acasti Pharma Inc. (Nasdaq: ACST) (Acasti or the Company), a late-stage, biopharma company advancing GTx-104, its novel injectable formulation of nimodipine that addresses high unmet medical needs for a rare disease, aneurysmal subarachnoid hemorrhage (aSAH), today announced that it is changing its name to Grace Therapeutics, Inc. (Grace Therapeutics). Grace Therapeutics was the name of the company developing GTx-104 prior to its merger with Acasti in 2021. Grace Therapeutics will begin trading on Nasdaq under the trading symbol “GRCE” at the open of the market on October 28, 2024 and all company branding including corporate website will be updated accordingly. “The Grace Therapeutics brand reconnects us to our roots that are steeped in scientific innovation and highlights our transformative journey,” said Prashant Kohli, CEO of Acasti. “The breakthrough formulation of GTx-104 is the result of a decade of research by our exceptional scientific team while Grace Therapeutics was located in the pharma industry research corridor of New Jersey. We have continued to make significant progress in the clinical development plan of GTx-104, including full enrollment of the STRIVE-ON trial and anticipate a data readout in early calendar 2025 with an expected submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in the first half of calendar 2025. “In addition to advancing GTx-104 over the past 18 months, we successfully restructured to an agile biopharma model, rebuilt the management team, prioritized the pipeline, divested legacy assets, strengthened the balance sheet, and re-domiciled to the United States as a Delaware corporation. We believe these steps offer several potential benefits, including a U.S. corporate structure that should increase the company’s attractiveness and marketability to potential strategic partners and global institutional investors. We are proud of the progress made within a relatively short timeframe and look forward to fully realizing the Company’s value under the Grace Therapeutics brand.” The Company will host a Key Opinion Leader (KOL) event titled Virtual KOL Event on GTx-104 in aneurysmal Subarachnoid Hemorrhage, on November 20, 2024 at 2pm Eastern Time.
