Dimension Therapeutics Announces Presentations at the Upcoming American Society for Gene and Cell Therapy (ASGCT) Annual Meeting

CAMBRIDGE, Mass., April 18, 2016 (GLOBE NEWSWIRE) -- Dimension Therapeutics, Inc. (NASDAQ:DMTX), a biopharmaceutical company advancing novel, adeno-associated virus (AAV) gene therapies targeting the liver, a central organ for devastating rare diseases, today announced that oral and poster presentations will highlight the progress of two of Dimension’s lead development candidates in hemophilia B and A, DTX101 and DTX201 respectively, during the 19th ASGCT Annual Meeting, which will take place in Washington, DC, on Friday, May 4-7, 2016. Poster presentations will also address novel scientific approaches to the pharmaceutical development and manufacturing process of the DMTX mammalian platform that is supporting Dimension’s broad product pipeline across both hemophilia and the inherited metabolic disorders.

“We are pleased that the ASGCT has chosen to highlight our highly productive collaborative partnership in translational research with the lab of Jim Wilson, MD, PhD, professor of Medicine and Pediatrics at the Perelman School of Medicine at the University of Pennsylvania,” said Annalisa Jenkins, MBBS, MRCP, Chief Executive Officer of Dimension. “The preclinical in vivo pharmacology program at Dimension continues to provide compelling evidence on our pipeline of gene therapy programs supporting our goal of multiple IND filings in the coming year. We are committed every day to innovation in the science and medicine of rare diseases associated with the liver and in the delivery of a robust, sustainable quality manufacturing platform.”

Dr. Jenkins added, “We are proud of this work and the continued momentum of our hemophilia programs and look forward to engaging with members of the gene therapy and rare disease community at ASGCT next month.”

The presentation details are as follows:
