Acasti Pharma Retains Crescendo Communications for Investor Relations Services in the United States

LAVAL, Québec, May 18, 2018 (GLOBE NEWSWIRE) -- Acasti Pharma Inc. (NASDAQ:ACST) (TSX-V:ACST) (the “Company” or “Acasti Pharma”), 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 has retained Crescendo Communications, LLC ("Crescendo”) to provide investor relations services for the Company in the United States.

Jan D’Alvise, president and CEO of Acasti Pharma, noted, “We look forward to working closely with Crescendo to more proactively communicate our story in the U.S. 2018 is shaping up to be a pivotal year, and we are committed to maximizing value for shareholders.”

“We look forward to working closely with Acasti Pharma to help increase awareness of the Company within the investment community,” said David Waldman, CEO of Crescendo Communications.  “Phase 1 and phase 2 clinical results suggest CaPre® has the potential to become the “best-in-class” cardiovascular drug for treating severe Hypertriglyceridemia (HTG), with approximately three to four million people diagnosed in the U.S. alone (Archives of Internal Medicine, “The Ford Study”, 2009). We believe that a significant unmet medical need exists for an effective, safe and well-absorbing omega-3 therapeutic that can also demonstrate a positive impact on the major blood lipids associated with cardiovascular disease risk.  CaPre could address this need if the Phase 3 studies reproduce the results observed in Phase 2.  In this case, there is potential to expand the addressable market for CaPre’s initial indication to the roughly 36 million patients with high triglycerides (200 – 499 mg/dL) (The American Heart Association Scientific Statement on Triglycerides and Cardiovascular Disease, 2011), although at least one additional clinical trial would likely be required to expand CaPre’s indications to this segment.”

The investor relations services agreement with Crescendo (the “Agreement”) is for an indeterminate term and may be terminated by Acasti Pharma at any time upon 30 days’ notice. Under the terms of the Agreement, Crescendo will receive a monthly fee of US$10,000 and eligible expenses will be reimbursed. The Agreement is subject to the approval of the TSX Venture Exchange.

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. 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. CaPre is being evaluated in a Phase 3 clinical program in patients with severe hypertriglyceridemia, a market that includes 3 to 4 million patients in the U.S. and may expand significantly if omega-3s demonstrate long-term cardiovascular benefits in on-going outcomes studies. Acasti Pharma’s strategy is to commercialize CaPre in the U.S. and the company is pursuing partnerships to market CaPre in major countries around the world.
