PRINCETON, N.J., Feb. 12, 2024 (GLOBE NEWSWIRE) -- Acasti Pharma Inc. (Nasdaq: ACST) (Acasti or the Company), a late-stage, biopharma company advancing GTX-104, its novel formulation of nimodipine that addresses high unmet medical needs for a rare disease, aneurysmal subarachnoid hemorrhage (aSAH), today announced financial results and business highlights for the quarter ended December 31, 2023.

"During the third quarter we continued to execute our focused strategy around our biggest value driver program GTX-104 and its pivotal Phase 3 STRIVE-ON safety trial (the STRIVE-ON trial–NCT05995405). Having dosed the first patient in October, we’ve continued to enroll more patients and sites since that time,” said Prashant Kohli, CEO of Acasti. “With our balance sheet enhanced by the $7.5 million private placement secured last quarter and prudent use of resources announced in our strategic realignment plan in May 2023, our cash runway is now expected to extend into the second calendar quarter of 2026, well beyond our potential submission of GTX-104 NDA in the first half of 2025.”

Third Quarter 2024 Financial Results

On June 29, 2023, the Board of Directors of the Company approved a reverse stock split of the Company's Class A common shares, no par value per share, at a ratio of 1-for-6, which was effective on July 10, 2023. All references below to the number of common shares, price per share and weighted average number of shares outstanding have been adjusted to reflect such reverse stock split.

The Company reported a net loss of $2.4 million, or $0.21 per share, for the three months ended December 31, 2023, a decrease of $1.5 million from the net loss of $3.9 million, or $0.52 per share, for the three months ended December 31, 2022. The Company’s net loss of $2.4 million for the three months ended December 31, 2023, included $3.0 million of operating expenses, that were offset in part by interest income of $0.3 million from our investments, $0.1 million gain on change in fair of derivative warrant liabilities and $0.2 million in income tax recovery.

Research and development expenses for the three months ended December 31, 2023 totaled $1.4 million compared to $2.5 million for the three months ended December 31, 2022. The decrease from the prior year period was mainly attributable to the Company’s strategic realignment plan to align the organizational and management cost structure to prioritize resources to GTX-104, thereby reducing losses to improve cash flow and extend available cash resources.

General and administrative expenses were $1.6 million for the three months ended December 31, 2023, unchanged from $1.6 million for the three months ended December 31, 2022.

The Company’s cash, cash equivalents and short-term investments as of December 31, 2023, were $25.1 million. The Company believes its cash, cash equivalents and short-term investments are sufficient to fund its operations into the second calendar quarter of 2026.

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.

About GTX-104

GTX-104 is a clinical stage, novel, injectable formulation of nimodipine being developed for intravenous infusion (IV) 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. 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.
