Repligen HDAC inhibitors progress

5/7/13 - REPLIGEN CORP - 10-Q - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS . http://www.pharmacychoice.com

Our third clinical development program was targeted at Friedrich's Ataxia and led by RG2833, a class I histone deacetylase ("HDAC") inhibitor. RG2833 has received Orphan Drug designation from the FDA and European Commission. We initiated a single, ascending dose Phase 1 study of RG2833 in Friedreich's Ataxia patients in Italy in the fourth quarter of 2012 and completed the patient dosing in the quarter ended March 31, 2013. We believe the results of this trial, which we are currently analyzing, may be an important consideration for any third-party that may wish to pursue a development or commercialization agreement with us for RG2833. We expect that any additional development activities that we may pursue in the future will be largely supported by sponsors or collaborators.
