Acasti Pharma Announces the Issuance of Additional Patents for GTX-104 and GTX-101

LAVAL, Québec, June 14, 2022 (GLOBE NEWSWIRE) — Acasti Pharma Inc. (“Acasti” or the “Company”) (Nasdaq: ACST and TSX-V: ACST), today announced that three composition of matter patents for GTX-104 were issued by The United States Patent and Trademark Office, the Japanese Patent Office, and the Australian Patent Office. Additionally, one new patent for GTX-104 was awarded by the Indian Patent Office. These granted patents are all valid until 2037.

GTX-104 is a novel formulation of nimodipine for IV infusion to treat patients suffering from Subarachnoid Hemorrhage (SAH), which is caused by a ruptured aneurysm and is estimated to affect about 110,000 patients per year, in the US and Europe. Acasti recently reported positive results for a pharmacokinetic (PK) study, with intravenous GTX-104 meeting all endpoints. Acasti is now working with the U.S. FDA to commence a Phase 3 study on GTX-104, which is expected to be the final step required to seek regulatory approval.

In addition, the Canadian Intellectual Property Office has issued a notice of allowance for a composition of matter patent for GTX-101, a topical spray of bupivacaine targeting Postherpetic Neuralgia (PHN). PHN is a persistent and often debilitating neuropathic pain caused by nerve damage from the varicella zoster virus (shingles), which may persist for months and even years. The granted patent is valid until 2036.

Jan D’Alvise, Chief Executive Officer of Acasti, stated, “We are pleased to report that our progress in the clinic is being matched by our progress protecting our intellectual property, both in North America and internationally. We are happy to highlight that we now hold 5 U.S. patents for GTX-104.”

“GTX-101 could provide significant benefits over the current standard of care including greater convenience, faster onset of action and longer duration of pain relief and we are pleased to see that we have additional IP coverage in Canada. We expect that a single-dose clinical trial will be launched soon to study the PK profile of GTX-101 in healthy volunteers,” D’Alvise concluded.
