LAVAL, Québec, June 21, 2022 (GLOBE NEWSWIRE) — Acasti Pharma Inc. (“Acasti” or the “Company”) (Nasdaq: ACST and TSX-V: ACST), a late-stage, specialty pharma company with drug delivery capability and technologies addressing rare and orphan diseases, today announced financial and operational results for the fiscal year ended March 31, 2022.

Recent Highlights

• Acasti’s 3 lead programs are on schedule to initiate new clinical trials in the second half of calendar 2022 including:
  • GTX-104 – Initiate Phase 3 safety trial (Q4 calendar year)
  • GTX-102 – Initiate PK Bridging Study (Q3 calendar year)
  • GTX-101 – Initiate Single Dose and Multiple Ascending Dose PK studies (Q3 calendar year)
• Company ended the year (March 31, 2022) with $43.7 million in cash, cash equivalents and short-term investments.
• Achieved positive top line results for the pharmacokinetic (PK) bridging study with IV GTX-104, our lead drug candidate for the treatment of Subarachnoid Hemorrhage (SAH), with the study having met all its planned endpoints.
• Preparing the GTX-104 PK bridging study results for submission to the U.S. Food and Drug Administration (FDA), along with the Company’s proposed design for the Phase 3 safety study, which remains on track to start in the second half of calendar 2022. The safety study is expected to be the final step required to seek regulatory approval under the 505(b)(2) regulatory pathway before submitting a New Drug Application to the FDA.

The patent is expected to be valid until 2037.
• Japanese Patent Office granted a composition of matter patent for the Company’s GTX-101 topical spray targeting postherpetic neuralgia (PHN). The granted patent is valid until 2036.

Management Discussion

Jan D’Alvise, Chief Executive Officer of Acasti said, “Fiscal year 2022 was a truly transformative year for Acasti, and I am extremely pleased with all our team has accomplished over the last 12 months. In FY’22, we pivoted as a company, and acquired Grace Therapeutics in August 2021. This gave us a new mission of leveraging Grace’s proprietary drug delivery technologies to reformulate and repurpose marketed medicines for indications in rare and orphan diseases, where significant unmet medical needs exist. We now have three drug candidates advancing in clinical development, and all three have already received Orphan Drug Designation by the FDA, which could grant us 7 years of market exclusivity in the US. Just a few weeks ago we announced that GTX-104, a novel IV formulation of nimodipine, met all its PK Bridging Study endpoints, and we are now working with the FDA to commence a Phase 3 study, which we expect to be the final step required to seek regulatory approval. We also advanced our other drug candidates, GTX-102 and GTX-101, into the clinic with significant potential milestones expected later this calendar year.”

D’Alvise continued, “We are confident that our strong balance sheet, which shows $43.7 million of cash and short-term investments as of March 31, 2022, will allow us to advance GTX-104 through Phase 3 and to potential FDA submission, while similarly advancing GTX-102 and GTX-101 to key value inflection points. We look forward to the coming fiscal year with tremendous excitement.”

Program Updates

GTX-104:

GTX-104 is a clinical stage, novel formulation of nimodipine for IV infusion in SAH patients. In May 2022, the Company announced top line results of its pharmacokinetic (PK) bridging study with IV GTX-104 met all its planned study endpoints. The primary objective of the study was to evaluate the relative bioavailability of IV GTX-104 compared to oral nimodipine in healthy adult male and female subjects, while the secondary objective was to assess its safety and tolerability. Importantly, the inter- and intra-subject variability was also much lower for GTX-104 as compared with oral nimodipine. The Company believes because of its better absorption profile and more consistent blood levels, GTX-104 may provide physicians with a more reliable and effective treatment for patients with SAH. This could be a key advantage, as GTX-104 could help to reduce the incidence of hypotensive events and vasospasm, which require immediate and costly intervention and can lead to worse outcomes for the patient. The Company plans to submit its recent PK Bridging data results to the FDA, along with its proposed study design for the Phase 3 safety study, which remains on schedule to start in the second half of calendar 2022. The safety study is expected to be the final step required to seek regulatory approval under the 505(b)(2) regulatory pathway before submitting a New Drug Application to treat SAH patients to the FDA.

GTX-102:

GTX-102 is a novel, concentrated oral-mucosal spray of betamethasone intended to improve neurological symptoms of A-T for which there are currently no FDA-approved therapies. GTX-102 is comprised of the glucocorticoid betamethasone that can be sprayed conveniently over the tongue of the A-T patient. The Company plans to initiate the PK bridging study of GTX-102 in the third calendar quarter of 2022 and is expected to report out results before the end of calendar 2022. Based on the FDA’s guidance and assuming the PK bridging study meets its primary endpoint, the Company plans to conduct a Phase 3 safety and efficacy trial in A-T patients. The Phase 3 study is expected to be initiated in the first half of calendar 2023. If both studies meet their primary endpoints, an NDA filing under Section 505(b)(2) would follow.

GTX-101:

GTX-101 is a non-narcotic, topical bio-adhesive film-forming bupivacaine spray designed to treat PHN, the severe and often debilitating nerve pain that can persist following a shingles infection. The data from a single dose Phase 1 clinical trial for GTX-101 along with regulatory guidance from the FDA’s Division of Anesthesiology has informed the design of additional preclinical toxicology studies, and a proposed clinical and regulatory pathway to approval. The Company plans to initiate both a single dose study and a multiple ascending dose study in healthy human volunteers in calendar Q3, 2022. Results for these studies are expected to report out before the end of calendar 2022. Results from these pre-clinical and clinical studies are required before the Company can initiate its Phase 2 program in PHN patients, which is expected to start in early calendar 2023.

Fiscal 2022 Financial Results (U.S. Dollars)

The Company’s consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”).

Research and development expenses, net of government assistance for the twelve months ended March 31, 2022 totaled $5.6 million compared to $4.2 million for the twelve months ended March 31, 2021. Our research and development during the year ended March 31, 2022 was focused primarily on advancing the clinical development programs for our GTX 104, GTX 102, and GTX 101 drug candidates, which were acquired in the Grace merger completed on August 27, 2021. Research and development expenses during the year ended March 31, 2021 related to the completion of our TRILOGY Phase 3 clinical program for CaPre, and due diligence activities on various strategic options under review prior to the Grace merger announcement.

General and administrative expenses for the year ended March 31, 2022 were $9.3 million compared to $5.5 million for the year ended March 31, 2021. This increase was a result of increased legal, tax, accounting and other professional fees related to the Grace merger, and the renewal of our at-the-market program.

Loss from operating activities for the year ended March 31, 2022 was $15.6 million compared to a $16.4 million loss for the year ended March 31, 2021.

The Company incurred net financial income (expenses) gain for the year ended March 31, 2022 of $5.1 million compared to $(3.3) million for the year ended March 31, 2021. The change is primarily due to change in fair value of derivative warrant liabilities.

Net loss and total comprehensive loss for the year ended March 31, 2022 was $9.8 million, or $0.27 loss per share, compared to a net loss of $19.7 million, or $1.33 loss per share for the year ended March 31, 2021.

Cash, cash equivalents and short-term investments totaled $43.7 million as of March 31, 2022 compared to $60.7 million in cash, cash equivalents and short-term investments as of March 31, 2021. Based on management’s current projections, current cash is expected to fund our lead asset GTX-104 through to NDA submission, and GTX-102 and GTX-101 to additional key milestones.
