Acasti Catapults on $133M Deal With Unnamed Leading China-Based Pharma

LAVAL, QUEBEC -- (Marketwired) -- Nov 20, 2017 -- Acasti Pharma ( NASDAQ : ACST )( TSX VENTURE : 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 the company recently entered into a non-binding term sheet with a leading China-based pharmaceutical company. Completion of the transaction is subject to further negotiation and execution of a definitive agreement, which once signed would grant an exclusive license to the Chinese pharmaceutical company to commercialize CaPre in certain Asian countries, including China. With the high prevalence of hypertriglyceridemia in Asia, this potential partnership presents a significant opportunity for Acasti and CaPre.

If a definitive agreement is reached and signed, the term sheet contemplates that Acasti would receive an upfront payment of US$8 million upon signing, plus potential additional regulatory and commercial milestone payments in excess of US$125 million, and tiered double-digit royalties on net sales. The term sheet is preliminary and non-binding at this stage and the license, upfront payment, possible milestone payments, and royalties contemplated by it will only become operative if definitive documents are executed. It is possible that no definitive agreement will be reached or, if a definitive agreement is reached, that its terms or conditions may differ from those described above.

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 allows for better absorption 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.

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 company’s strategy is to initially develop and commercialize CaPre for the 3 to 4 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.
