Insights

The completion of patient enrollment in Acasti Pharma's Phase 3 STRIVE-ON safety trial for GTX-104 is a significant milestone in the development of a potential new treatment for aneurysmal subarachnoid hemorrhage (aSAH). This achievement, ahead of schedule, demonstrates strong execution and investigator support, which are positive indicators for the trial's progress.

Key points to consider:

  • The trial compares GTX-104, a novel injectable formulation of nimodipine, to oral nimodipine in 100 aSAH patients across 25 U.S. hospitals.
  • The primary endpoint focuses on safety, particularly the incidence of adverse events like hypotension.
  • Data readout is expected in early 2025, with an NDA submission planned for the first half of 2025.

If successful, GTX-104 could address challenges associated with oral nimodipine administration, potentially improving the standard of care for aSAH patients. However, investors should note that the trial's success and subsequent regulatory approval are not guaranteed and the timeline to potential commercialization is still extended.

While the completion of patient enrollment is a positive development for Acasti Pharma, investors should consider several financial implications:

  • With a market cap of just $25.96 million, Acasti is a micro-cap company, which typically carries higher risk.
  • The extended timeline to potential commercialization (NDA submission in 1H 2025) means continued cash burn without immediate revenue prospects from GTX-104.
  • Successful trial results could significantly increase the company's value, but this is contingent on positive data readouts and FDA approval.
  • Investors should assess Acasti's cash position and burn rate to ensure sufficient funding through the trial completion and NDA submission.

The orphan drug status for aSAH treatment could provide market exclusivity and pricing power if approved, potentially leading to substantial returns. However, the current valuation suggests the market is cautious, likely due to the inherent risks in drug development and the company's financial position.

Data Readout Expected Early Calendar 2025; NDA Submission on Track for 1H Calendar 2025

PRINCETON, N.J., Sept. 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 patient enrollment has been completed in the Company’s Phase 3 STRIVE-ON safety trial (the STRIVE-ON trial–NCT05995405). The STRIVE-ON trial is a prospective, open-label, randomized (1:1 ratio), parallel group trial of GTX-104 compared with oral nimodipine, in 100 patients hospitalized for aSAH. Approximately 25 hospitals in the U.S. are participating.

“We are excited to announce the completion of enrollment in our STRIVE-ON trial, a significant milestone for the Company achieved ahead of our original expectations,” said Prashant Kohli, CEO of Acasti. “I'm proud of our team's diligence in executing the clinical trial plan, and thankful to our investigators for their strong support. We believe that if approved, GTX-104 has the potential to address significant challenges with oral nimodipine administration and may transform the standard of care for patients with aSAH. We anticipate a data readout from the STRIVE-ON trial in early calendar 2025, and plan to submit a New Drug Application to the U.S. Food and Drug Administration in the first half of next year, consistent with our timeline.”

The primary endpoint of the STRIVE-ON trial is safety, and will be measured as comparative adverse events, including hypotension, between the two patient groups.

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 Acasti 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.
