Acasti Pharma Provides Update on Timing of Topline Results for TRILOGY 1 Phase 3 Trial of CaPre

Expects to report Trilogy 1 topline results in January 2020
with topline results for Trilogy 2 still expected by the end of January 2020LAVAL, Québec, Dec. 23, 2019 (GLOBE NEWSWIRE) — Acasti Pharma Inc. (“Acasti or the “Company”) (NASDAQ: ACST – TSX-V: ACST), a biopharmaceutical innovator focused on the research, development and commercialization of its prescription drug candidate CaPre® (omega-3 phospholipid) for the treatment of severe hypertriglyceridemia (triglyceride blood levels from 500 mg/dL to 1500 mg/dL), today announced that it expects to report its topline results for the TRILOGY 1 pivotal Phase 3 trial of CaPre in January 2020. The reporting of Trilogy 1 was postponed due to an unexpected delay in data processing and transfer from the central testing laboratory to the statistical consultants for independent and external validation. Acasti regrets the delay due to factors outside its control, and now anticipates to report topline results in January 2020.  As requested by the Investment Industry Regulatory Organization of Canada (IIROC), due to market volatility, the Company indicates that it has no material update to provide at this time beyond the above timing update and independent and external validation exercise that is underway.Implementation of the Trilogy 2 Study remains on track, and the Company continues to expect the last patient to complete their final visit in early January 2020, and expects to report topline results in Trilogy 2 towards the end of January 2020.Topline results will include a readout of the primary endpoint, which is intended to show CaPre’s overall impact on lowering triglycerides (TGs) after 12 weeks compared to placebo. Safety and tolerability (e.g. overall adverse events (AE) and serious AE rate, and any discontinuation due to AEs) will also be reported.  Other important secondary endpoints such as Non-HDL cholesterol, HDL cholesterol, and VLDL may now also be reported with the topline results. As previously disclosed, subgroup analyses of certain key secondary (LDL) and exploratory markers (HbA1c) will be dependent on combining results from both studies, and would be expected sometime later in the first quarter of 2020. NOVEMBER ATM DISTRIBUTION UPDATEAcasti also provided an update on its previously adopted at-the-market program (the “ATM Program”) for the month of November 2019, as required pursuant to the policies of the TSX Venture Exchange (the “November ATM Distribution”).
