PRINCETON, N.J., Nov. 13, 2023 (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 the high unmet medical needs for a rare disease, aneurysmal subarachnoid hemorrhage (aSAH), today announced financial results and business highlights for the quarter ended September 30, 2023.

“During our second quarter we achieved significant strategic milestones, including initiating our pivotal Phase 3 STRIVE-ON randomized trial (the STRIVE-ON trial–NCT05995405) and securing $7.5 million, before expenses, in private placement financing with fundamental investors to provide funding well beyond the anticipated submission of GTX-104 NDA to the U.S. Food and Drug Administration (FDA) in the first half of 2025,” said Prashant Kohli, CEO of Acasti. “This financing, led by ADAR1 with participation from other investors including existing shareholders and Acasti’s Board Chairman, represents an important vote of confidence from the investment community. The potential of GTX-104 as an improvement over the current standard of care in aSAH was further reinforced in the virtual webinar we hosted in October with W. Taylor Kimberly, MD, PhD (Massachusetts General Hospital), which highlighted the key potential advantages of our novel injectable formulation over oral nimodipine. With our STRIVE-ON trial actively enrolling patients and a stronger balance sheet, we are well positioned to advance GTX-104 and realize its clinical and commercial prospects as a potential new treatment standard for aSAH.”

Second Quarter 2024 Financial Results

The Company’s consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America and are presented in U.S. dollars. 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.

• Net loss $3.3 million or $0.43 per share for the three months ended September 30, 2023 decreased by $1.7 million from the net loss of $5.0 million or $0.66 per share for the three months ended September 30, 2022. Our net loss of $3.3 million for the three months ended September 30, 2023, included $2.1 million loss from our operating activities and $1.8 million in expenses from the change in fair value of our warrant liabilities. These expenses were partially offset from interest income of $200 thousand from our investments and $446 thousand in income tax recovery.
• Research and development expenses before depreciation, amortization and stock-based compensation, expenses for the three months ended September 30, 2023 totaled $0.4 million compared to $3.1 million for the three months ended September 30, 2022. The net decrease was mainly attributable to the restructuring to align our organizational and management cost structure to prioritize resources to GTX-104 and reduce losses to improve cash flow and extend available cash resources.
• General and administrative expenses totaled $1.4 million before stock-based compensation and depreciation expense for the three months ended September 30, 2023, an increase of $0.1 million from $1.3 million for the three months ended September 30, 2022. The increase was primarily a result of an increase in legal, tax, accounting and other professional fees, partially offset by decreased salaries and benefits due to a reduction in general and administrative headcount due to our restructuring and reorganization of our management structure.
• Cash and cash equivalents as of September 30, 2023, totaled $27.0 million, a decrease of $0.9 million compared to cash and cash equivalents totaling $27.9 million at March 31, 2023 primarily due to ongoing research and development activities and funding the restructuring expense, offset by the net proceeds of $7.3 million from our September 2023 private placement offering. Our average monthly spend of $1 million for the six months ended September 30, 2023 decreased by $0.6 million from our average monthly spend of $1.6 million for the six months ended September 30, 2022.
• As of September 30, 2023, the Company had 9,399,404 common shares issued and outstanding.

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.
