Acasti Pharma Presents CaPre Clinical Data at Nati

LAVAL, QUÉBEC--(Marketwired - May 18, 2017) - Acasti Pharma Inc. (NASDAQ:ACST)(TSX VENTURE:ACST) today announced the presentation of the CaPre ® (omega-3 phospholipid) bridging study results at the up-coming National Lipid Association Scientific Sessions in Philadelphia. Jean-François Lapointe, Ph.D, director of clinical development at Acasti, will present "Phase 1, Single-Dose, Comparative Bioavailability Study of CaPre, a Novel Omega-3 Derived from Krill Oil and Lovaza® under Fasting and Fed Conditions," on May 20, 2017 from 12:10-12:30 p.m. ET in the Franklin B room at the Philadelphia Marriot Downtown.

"The data highlights the preserved exposure and perhaps retained efficacy in patients taking CaPre in either the fasted state or with a low-fat diet, which is the physician recommended diet for patients with severe hypertriglyceridemia," said Jean-François Lapointe, Ph.D., Acasti's director of clinical development. "The results of the bioavailability study support advancing CaPre into Phase 3 clinical development in order to build the evidence that CaPre may provide patients with severe hypertriglyceridemia a therapeutic treatment alternative that has a more comprehensive and positive impact on the major lipids associated with cardiovascular disease."

As previously reported, Acasti's open-label, randomized, four-way, cross-over, bioavailability study compared CaPre given as a single dose of 4 grams in fasting and fed states with the approved hypertriglyceridemia drug LOVAZA (omega-3-acid ethyl esters) in 56 healthy volunteers. The study met its primary objective and demonstrated that the levels of omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) following administration of CaPre did not exceed the levels following administration of LOVAZA in subjects who were fed a high-fat meal. These results support the basis for claiming a comparable safety profile of the two products. Furthermore, among subjects in the fasting state, CaPre demonstrated better bioavailability than LOVAZA, as measured by blood levels of EPA and DHA. The bioavailability of CaPre is not significantly reduced when taken with a low-fat meal versus a high-fat meal. This could represent a significant clinical advantage for CaPre since the administration with a low-fat meal represents a more attractive regimen for patients with hypertriglyceridemia who follow a restricted diet.

Acasti has successfully completed two Phase 1 and two Phase 2 clinical trials with CaPre for the treatment of hypertriglyceridemia, and continues on track to initiate the Phase 3 program in late 2017.

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 that help them to be better absorbed into the body. This allows for enhanced bioavailability and EPA and DHA blood levels compared to the "esterified" fish-oil omega-3 options such as LOVAZA.

About Acasti Pharma

Acasti Pharma 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. The corporation's strategy is to initially develop and commercialize CaPre for the three to four million patients in the U.S. with severe hypertriglyceridemia. Since its founding in 2008, Acasti Pharma 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.
