Acasti Pharma Announces Submission of TRILOGY 1 Briefing Package to FDA

FDA response expected on or before June 30, 2020

Acasti also received notice of issuance of a Composition of Matter Patent in Hong Kong

LAVAL, Quebec, April 30, 2020 (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, today announced that it submitted its briefing package on April 29, 2020 to the Food and Drug Administration (FDA) for review. The Company is currently awaiting comments, and expects a formal response from the FDA on or before June 30, 2020.

As previously reported, Acasti filed its meeting request at the end of March, and this briefing package is now intended to provide the FDA with a review of the relevant TRILOGY 1 data and audit findings, with the objective to gain alignment on the interpretation of the TRILOGY 1 results and implications for TRILOGY 2. The Company will also seek the FDA’s input on Acasti’s proposed revisions to the pre-specified TRILOGY 2 statistical analysis plan (SAP), and explore and hopefully reach agreement on a plan for pooling the data from TRILOGY 1 and TRILOGY 2 to support an NDA filing.  Acasti continues to remain blinded to the TRILOGY 2 results, and intends to update the statistical analysis plan (SAP) with these revisions if the FDA agrees.

Jan D’Alvise, President and CEO of Acasti Pharma, commented, “We have submitted our briefing package to the FDA for their review, and are now awaiting their formal response. We remain optimistic that we may still have a viable path toward filing an NDA. We look forward to the FDA’s feedback on our briefing package, and expect that they will provide valuable guidance on the next steps to be taken towards the unblinding of TRILOGY 2. We will provide more information about our TRILOGY 1 findings, and the FDA’s response to our briefing package and our questions after we get it.”

Acasti also announced today that it has received notice of issuance of a composition of matter patent to be awarded by the Intellectual Property Office in Hong Kong. This new patent grants claims for any composition containing EPA and DHA, where at least 50% of the composition consists of phospholipids.

About CaPre (omega-3 phospholipid)

Acasti’s prescription drug candidate, CaPre, is a highly purified omega-3 phospholipid concentrate derived from krill oil, and is being developed to treat severe hypertriglyceridemia, a metabolic condition that contributes to increased risk of cardiovascular disease and pancreatitis. Its omega-3s, principally EPA and DHA, are either “free” or bound to phospholipids, which allows for better absorption into the body. Acasti believes that EPA  and  DHA  are  more efficiently transported by phospholipids sourced from krill oil than the EPA and DHA contained in fish oil that are transported either by triglycerides (as in dietary supplements) or as ethyl esters in other prescription omega-3 drugs, which must then undergo additional digestion before they are ready for transport in the bloodstream. Clinically, the phospholipids may not only improve the absorption, distribution, and metabolism of omega-3s, but they may also decrease the synthesis of LDL cholesterol in the liver, impede or block cholesterol absorption, and stimulate lipid secretion from bile. In two Phase 2 studies, CaPre achieved a statistically significant reduction of triglycerides and non-HDL cholesterol levels in patients across the dyslipidemia spectrum from patients with mild to moderate hypertriglyceridemia (patients with TG blood levels between 200mg/dl and 500mg/dl) to patients with severe hypertriglyceridemia (those with TG levels above 500mg/dl). Furthermore, in the Phase 2 studies, CaPre demonstrated the potential to actually reduce LDL, or “bad cholesterol”, as well as the potential to increase HDL, or “good cholesterol”, especially at the therapeutic dose of 4 grams/day. The Phase 2 data also showed a significant reduction of HbA1c at a 4 gram dose, suggesting that due to its unique omega-3/phospholipid composition, CaPre may actually improve long-term glucose metabolism. Acasti’s TRILOGY Phase 3 program is currently underway.

About Acasti Pharma

Acasti is a biopharmaceutical innovator advancing a potentially best-in-class cardiovascular drug, CaPre® (omega-3 phospholipid), for the treatment of hypertriglyceridemia, a chronic condition affecting an estimated one third of the U.S. population. Since its founding in 2008, Acasti has focused on addressing a critical market need for an effective, safe and well-absorbing omega-3 therapeutic that can make a positive impact on the major blood lipids associated with cardiovascular disease risk. The Company is developing CaPre in a Phase 3 clinical program in patients with severe hypertriglyceridemia, a market that includes 3 to 4 million patients in the U.S. The addressable market may expand significantly if omega-3s demonstrate long-term cardiovascular benefits in on-going outcomes studies (REDUCE-IT and STRENGTH). Acasti may need to conduct at least one additional clinical trial to expand CaPre’s indications to this segment. Acasti’s strategy is to commercialize CaPre in the U.S. and the Company is pursuing development and distribution partnerships to market CaPre in major countries around the world.
