§  
EBITDA for the three-month period ended May 31, 2011 resulted in a negative $695,000, compared to a negative $350,000 obtained during the corresponding period ended May 31, 2010.

“As forecasted, Acasti continued to invest in research and development, mostly for the development of CaPre™, Acasti’s prescription drug, during this first quarter.  The recent approval from Health Canada to enter into a phase II clinical trial, lead us to invest in additional fundamental and strategic research and development in the future”, stated Xavier Harland, Chief Financial Officer.  “The ongoing Rights Offering, generated a significant amount of interest yet and should provide sufficient financing to pursue the clinical development of Acasti’s prescription drug, CaPre™, through an Investigational New Drug application (IND) with the US Food and Drug Administration (FDA)”, he added.
 
“This quarter and recent achievements, named the listing of Acasti shares on the TSX-Venture, the Clinical Trial Application (CTA) approval, the rights offering initiation and the nomination of a new member to Acasti management team, contribute not only to build Acasti’s fundamental value but also to reach additional value creation milestones in the near future” stated Tina Sampalis.
