European Commission Ratifies Positive CHMP Opinion for the Renewal of Translarna™ Marketing Authorization for the Treatment of Nonsense Mutation Duchenne Muscular Dystrophy

SOUTH PLAINFIELD, N.J., Jan. 9, 2017 /PRNewswire/ -- PTC Therapeutics, Inc. (NASDAQ: PTCT) announced that it received notification today from the European Commission (EC) of its adoption of a positive decision granting annual renewal of the conditional marketing authorization for Translarna (ataluren). The positive decision is based on the recent renewal recommendation by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA). The authorization renewal allows the Company to market Translarna for the treatment of nonsense mutation Duchenne muscular dystrophy (nmDMD) in ambulatory patients aged five years and older in the 28 countries that are Member States of the European Union, as well as European Economic Area members Iceland, Liechtenstein and Norway. As a specific obligation of the renewal, the Company will conduct an additional trial of Translarna in nmDMD. 

"As we continue towards our goal of providing Translarna to all who may benefit, we are pleased by the EC ratification of the recent CHMP positive opinion," said Stuart W. Peltz, Ph.D., Chief Executive Officer, PTC Therapeutics. "This important regulatory milestone supports the continued growth of our sustainable ex-US business in both the European Union and countries that reference the authorization. Duchenne is a rapidly progressive disease and physicians need access to medicines, like Translarna, that have the potential to slow the devastating progression of this disorder."
