FDA Clears Acasti's Investigational New Drug Submission to Conduct PK Trial

LAVAL, Quebec, Jan. 9, 2014 (GLOBE NEWSWIRE) -- Acasti Pharma Inc. ("Acasti" or the "Corporation") (Nasdaq:ACST) (TSX-V:APO), an emerging biopharmaceutical company, announces that the U.S. Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) submission to initiate a Pharmacokinetic (PK) trial of CaPre^® in the U.S., having found no objections with the PK trial design, protocol, or safety profile of CaPre^®. Following the clearance, Acasti engaged Quintiles, the world's largest provider of biopharmaceutical development and commercial outsourcing services, to conduct its PK study.

"Today's announcement takes us another step towards securing regulatory approval to distribute and market CaPre^® as a prescription drug in the U.S.," highlighted Mr. Henri Harland, President and CEO of Acasti. "With this achievement, we are moving forward as planned with our research and clinical development programs for our investigational new drug CaPre^®."

The PK trial is an open-label, randomized, multiple-dose, single-center, parallel-design study that will evaluate blood profiles and bioavailability of omega-3 phospholipids on 42 healthy volunteers taking single and multiple daily oral doses of 1, 2 and 4 grams of CaPre^®.

About Acasti Pharma Inc.

Acasti is an emerging biopharmaceutical company focused on the research, development and commercialization of new krill oil-based forms of omega-3 phospholipid therapies for the treatment and prevention of certain cardiometabolic disorders, in particular abnormalities in blood lipids, also known as dyslipidemia. Because krill feeds on phytoplankton (diatoms and dinoflagellates), it is a major source of phospholipids and polyunsaturated fatty acids ("PUFAs"), mainly eicosapentaenoic acid ("EPA") and docosahexaenoic acid ("DHA"), which are two types of omega-3 fatty acids well known to be beneficial for human health. CaPre^®, currently Acasti's only prescription drug candidate, is a highly purified omega-3 phospholipid concentrate derived from krill oil and is being developed to help prevent and treat hypertriglyceridemia, which is a condition characterized by abnormally high levels of triglycerides in the bloodstream. ONEMIA^®, a medical food and currently Acasti's only commercialized product, is a purified omega-3 phospholipid concentrate derived from krill oil with lower levels of phospholipids, EPA and DHA content than CaPre^®.
