Acasti Pharma announces patents for GTX-104 in Europe,

LAVAL, Quebec, March 22, 2022 (GLOBE NEWSWIRE) — Acasti Pharma inc. (“Acasti” or the “Company”) (Nasdaq: ACST and TSX-V: ACST), announces the following patent notifications and awards relating to the Company’s three lead drug candidates:

  • The European Patent Office has notified its intention to grant the company’s composition patent for GTX-104, an intravenous formulation of nimodipine for use in the treatment of patients with subarachnoid hemorrhage. The patent should be valid until 2037.
  • The United States Patent and Trademark Office has issued notice of acceptance of the company’s composition patent for GTX-102, a new, easy-to-use formulation of betamethasone for the oral mucosa intended to improve symptoms of ataxia-telangiectasia (AT) . AT is a progressive neurodegenerative genetic disease that mainly affects children, causing severe physical disability, for which no treatment currently exists. The patent should be valid until 2037.
  • The Japan Patent Office has granted a composition of matter patent for the Company’s GTX-101 topical spray targeting postherpetic neuralgia (PHN). PHN is a persistent and often debilitating neuropathic pain caused by nerve damage caused by the varicella zoster (shingles) virus, which can persist for months or even years. GTX-101 could offer significant advantages over the current standard of care, including greater convenience, faster onset of action, and longer duration of pain relief. The granted patent is valid until 2036.

“We are delighted to announce these latest patent notifications and awards, which significantly strengthen the intellectual property around Acasti’s three core programs, GTX-104, GTX-102 and GTX-101,” commented Jan D’Alvise, Chairman and CEO of Acasti. “These patents extend our intellectual property protection through at least 2036 and further validate our unique approach to drug development by combining new drug delivery technologies with established therapies to improve efficacy and safety, increase patient compliance and improve patient outcomes in a variety of rare and orphan diseases. We believe that these drug candidates could also benefit from a faster path to regulatory approval and commercialization through the FDA’s 505(b)(2) pathway. We are actively advancing each of these clinical programs and look forward to providing updates on our progress. »
