Achillion Announces Upcoming Presentations of Novel Research Into Complement Biology at the 58th Annual Meeting of the American Society of Hematology

Blue Bell, Pennsylvania, UNITED STATES

NEW HAVEN, Conn., Nov. 03, 2016 (GLOBE NEWSWIRE) -- Achillion Pharmaceuticals, Inc. (Nasdaq:ACHN) today announced that two abstracts have been accepted for poster presentation at the 58th Annual Meeting of the American Society of Hematology (ASH) in San Diego, CA, December 3 - 6, 2016. 

“The data to be presented at ASH expand Achillion's understanding of complement biology and demonstrate the potential advantages of inhibition of factor D in treatment of complement-mediated diseases,” said David Apelian, M.D., Ph.D. and Chief Medical Officer of Achillion Pharmaceuticals. “This and other research recently presented by Achillion scientists highlight the potential of our approach as we continue to advance ACH-4471, our first small-molecule factor D inhibitor, through clinical development.”

Upcoming Poster Presentations

The poster titled ‘Evaluation of bacteria-mediated potential “Bystander” hemolysis of PNH red cells in vitro: No evidence of significant complement classical or lectin pathway-mediated hemolysis induced by microorganisms.’ will be presented by Dr. Xuan Yuan from the laboratory of Dr. Robert Brodsky, Johns Hopkins University, a leading PNH expert. Other authors on the poster include: Guangwei Yang; Jane A. Thanassi; Manuel D. Galvan; Steven D. Podos and Mingjun Huang of Achillion, as well as Dr. Brodsky.

This research demonstrated that PNH red cells were not subjected to theoretical “bystander hemolysis” when incubated with the bacteria tested, suggesting no increased risk of pathogen-induced hemolytic breakthrough in PNH patients if treated with a complement alternative pathway (AP) inhibitor.

A second poster titled ‘Effect of complement inhibition by anti-C5 (eculizumab) or a small molecule inhibitor of Factor D (ACH-4471) on survival of meningococci in blood from vaccinated adults’ will be presented by Dr. Dan M. Granoff, UCSF Benioff Children’s Hospital, a world expert on meningococcal infections. Other authors are Monica Konar and Eduardo Lujan of UCSF Benioff Children’s Hospital.

Data from this research suggests that vaccination may be more effective in decreasing the risk of meningococcal disease in the presence of an AP inhibitor as compared to a C5 inhibitor.

Achillion may use words such as “expect,” “anticipate,” “project,” “intend,” “plan,” “aim,” “believe,” “seek,” “ estimate,” “can,” “focus,” “will,” “look forward,” “goal,” and “may” and similar expressions to identify such forward-looking statements. These forward-looking statements also include statements about: the Company’s expected plans, timing, data readouts and results from ongoing and planned clinical trials of both ACH-4471 and HCV development candidates being advanced by Janssen under the Company’s collaboration with Janssen; and statements concerning the Company’s strategic goals, milestone plans, and prospects. Among the important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are risks relating to, among other things Achillion’s ability to: advance the preclinical and clinical development of its complement factor D inhibitors under the timelines it projects in current and future preclinical studies and clinical trials; obtain and maintain patent protection for its drug candidates and the freedom to operate under third party intellectual property; demonstrate in any current and future clinical trials the requisite safety, efficacy and combinability of its drug candidates; obtain and maintain necessary regulatory approvals; establish commercial manufacturing arrangements; identify, enter into and maintain collaboration agreements with third-parties, including the current collaboration with Janssen; compete successfully in the markets in which it seeks to develop and commercialize its product candidates and future products; manage expenses; manage litigation; raise the substantial additional capital needed to achieve its business objectives; and successfully execute on its business strategies. Furthermore, because Janssen is solely responsible for the development and commercialization of our HCV assets under the exclusive worldwide license we granted to it and has the deciding vote on all collaboration matters, Janssen generally has full discretion over all development plans and strategies and may not advance the HCV programs in the time frames Achillion or Janssen projects, or at all, including with regard to the current and planned phase 2a and phase 2b combination trials that include our licensed drug candidates. These and other risks are described in the reports filed by Achillion with the U.S. Securities and Exchange Commission, including its Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2016, and its subsequent SEC filings.
