PRINCETON, N.J, Aug. 11, 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 June 30, 2023.

“During our first quarter we made substantial progress executing on the strategic vision we laid out in April, moving with full speed to prioritize development of GTX-104, streamline our operations, extend our cash runway to fully fund the clinical development of GTX-104, and strengthen our leadership team with industry leaders in our sector,” said Prashant Kohli, CEO of Acasti. “With FDA alignment of our proposed protocol and dosing regimen for our pivotal Phase 3 STRIVE-ON safety trial (the STRIVE-ON trial) now in hand, we are completing our advanced preparations for the trial, and plan to initiate it in the coming weeks. We expect to dose the first patient in this trial in the fourth quarter of this calendar year and, if successful, potentially submit an NDA for GTX-104 in the first half of calendar 2025. With the efficiencies gained through our operational realignment, we reiterate that our projected cash runway now extends to the second quarter of 2025, inclusive of the potential NDA submission. We are excited about the progress we have made and look forward to presenting the data highlighting the potential of GTX-104 at the NCS conference later next week.”

Recent Corporate Highlights 

• Implemented strategic realignment plan that extends projected cash runway through calendar Q2 2025
  • Prioritized resources to biggest value driver – GTX-104.
  • Significant extension of the Company’s cash runway facilitates the achievement of critical value inflection milestones, including a potential NDA filing for GTX-104.
  • Evaluation of strategic alternatives to maximize value of de-prioritized pipeline assets (GTX-102 and GTX-101) including out-licensing or sale.
• Announced alignment with FDA on the STRIVE-ON trial protocol.
  • The STRIVE-ON trial will be a prospective, open-label, randomized (1:1 ratio), parallel group trial of GTX-104 compared with oral nimodipine, in patients hospitalized for aSAH. Key trial design features include:

First 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 for the three months ended June 30, 2023, was $4.0 million, or $0.54 per share compared to $4.5 million, or $0.61 per share, for the three months ended June 30, 2022.
• Research and development expenses before depreciation, amortization and stock-based compensation expenses for the three months ended June 30, 2023 totaled $1.1 million compared to $2.3 million for the three months ended June 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 $1.7 million before stock-based compensation and depreciation expense for the three months ended June 30, 2023, an increase of $0.1 million from $1.6 million for the three months ended June 30, 2022. The increase was primarily a result of an increase in legal, tax, accounting and other professional fees.
• Restructuring cost for the three months ended June 30, 2023, totaled $1.5 million primarily consisting of employee severance costs. On May 8, 2023, the Company communicated its decision to terminate a substantial amount of its workforce as part of a plan that intended to align the Company’s organizational and management cost structure to prioritize resources to GTX-104 and reduce losses to improve cash flow and extend available cash resources.
• Cash and cash equivalents as of June 30, 2023, totaled $21.6 million, a decrease of $6.2 million compared to cash and cash equivalents totaling $27.8 million at March 31, 2023, primarily due to ongoing research and development activities, and funding the restructuring expense.
• As of June 30, 2023, the Company had 7,435,533 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.

About Acasti

Acasti is a late-stage biopharma company with drug candidates addressing rare and orphan diseases. Acasti’s novel drug delivery technologies have the potential to improve the performance of currently marketed drugs by achieving faster onset of action, enhanced efficacy, reduced side effects, and more convenient drug delivery. Acasti’s lead clinical assets have each been granted Orphan Drug Designation by the FDA, which provides seven years of marketing exclusivity post-launch in the United States, and additional intellectual property protection with over 40 granted and pending patents. Acasti’s lead clinical asset, GTX-104, is an intravenous infusion targeting aneurysmal Subarachnoid Hemorrhage (aSAH), a rare and life-threatening medical emergency in which bleeding occurs over the surface of the brain in the subarachnoid space between the brain and skull.
