Keynote Speaker: Dr. Perry Calias

Perry Calias specializes in the development of targeted therapies. As Senior Director for Shire HGT, he has championed the investigational effort for the intrathecal administration of recombinant enzymes for the treatment of the CNS manifestations associated with lysosomal diseases. In this capacity, he has led the research effort with regards to regulatory filings both within the US and abroad resulting in 3 clinical trials and several peer-reviewed articles. He has held various R&D positions at EyeGate Pharmaceuticals (Vice President, Research and Development), Eyetech Pharmaceuticals (Senior Director, Drug Delivery/Chemistry) and Draper Laboratories (Senior Technical Lead), and Genzyme Corporation (Senior Scientist, Biomaterials and Surgical Products Research Department). Dr. Calias is listed as an inventor on over 30 domestic and foreign patents/applications spanning 18 different patent families, including mRNA therapeutics, new polyethylene glycol-linker chemistries, noninvasive ocular delivery devices, nucleic acid-protecting strategies, and combination anti-angiogenic therapies. He obtained his Ph.D. in Bio-Organic Chemistry in 1996 and his M.S. in 1993 from Tufts University.
