SOUTH PLAINFIELD, N.J., July 25, 2016 /PRNewswire/ -- PTC Therapeutics, Inc. (NASDAQ: PTCT) today announced global regulatory updates on Translarna™ (ataluren) for the treatment of nonsense mutation Duchenne muscular dystrophy (nmDMD) and nonsense mutation cystic fibrosis (nmCF).
European update on Translarna for nmDMD
Over the last several months, PTC has been engaged in constructive discussions with the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) regarding the renewal of Translarna's marketing authorization. The company has been informed that the renewal assessment procedure cannot be completed by mid-year 2016, however PTC expects that Translarna's current marketing authorization status will remain valid until a decision is adopted by the European Commission. The CHMP has agreed to the proposal by PTC to submit a draft clinical trial protocol for further discussion, which includes seeking scientific advice from the EMA. The company is optimistic that these interactions will support the renewal of the marketing authorization of Translarna coupled with an obligation to conduct an agreed upon clinical trial.
"We appreciate all the effort put forth by the CHMP in this renewal process," said Stuart W. Peltz, Ph.D., Chief Executive Officer, PTC Therapeutics, Inc. "We are pleased that meanwhile patients will continue to have access to Translarna, the first-ever treatment approved for an underlying cause of Duchenne muscular dystrophy."
Translarna initially received marketing authorization in the European Economic Area for the treatment of nmDMD in 2014, subject to annual renewal and certain conditions. Translarna is currently available to patients in more than 20 countries outside of the U.S. commercially or through early access programs.
Phase 2 Clinical Study of Translarna for nmDMD in pediatric patients
As part of PTC's ongoing commitments under the European marketing authorization and to support the potential expansion of Translarna's label to younger patients, the company has initiated a pediatric clinical study of Translarna for the treatment of nmDMD in patients two to five years of age. This Phase 2, open-label, multiple-dose study will evaluate the safety and pharmacokinetics of Translarna in pediatric patients.
National Institute for Health and Care Excellence (NICE) guidance update
The National Institute for Health and Care Excellence (NICE) recently issued final guidance recommending Translarna for the treatment of nmDMD patients in England in connection with a Managed Access Agreement (MAA) with National Health Services England (NHS). As part of the MAA, the usual three-month funding period under local regulation has been waived by NHS, meaning Translarna could be available within weeks to nmDMD patients in England.
U.S. update on Translarna for nmDMD
As previously disclosed, PTC recently participated in discussions with the U.S. Food and Drug Administration (FDA) to discuss the Refuse to File (RTF) letter issued on February 22, 2016 with respect to the company's New Drug Application (NDA) for Translarna for the treatment of nmDMD. PTC recently submitted an appeal to escalate continuing discussions about the RTF decision to the next level of FDA management via the formal dispute resolution process within FDA's Center for Drug Evaluation and Research (CDER). This process exists to encourage open, prompt discussion of scientific and procedural disputes that arise during the drug development process between FDA and companies. Within the dispute resolution process, PTC is willing to consider multiple paths to advance a potential FDA approval, including the possibility of conducting an additional clinical trial under accelerated approval.
European update on Translarna for nmCF
During the third quarter of 2015, PTC submitted a variation to its marketing authorization requesting EMA approval of Translarna for the treatment of nmCF based on a post-hoc analysis of the company's previously completed Phase 3 clinical trial. Based on recent interactions with the CHMP, PTC no longer anticipates that the CHMP will issue its opinion regarding this submission in mid-2016. As previously communicated, PTC's confirmatory Phase 3 ACT CF trial is currently ongoing, and there is substantial risk that the results from this trial, expected in early 2017, will be required for approval.
PTC to Host Conference Call to Discuss Second Quarter Financial Results
PTC will host a webcast conference call to report its second quarter financial results and provide an update on the company's business and outlook on Thursday, August 4, 2016 at 4:30 p.m. (ET) after the closing of the market.
About Translarna™ (ataluren)
Translarna, discovered and developed by PTC Therapeutics, Inc., is a protein restoration therapy designed to enable the formation of a functioning protein in patients with genetic disorders caused by a nonsense mutation. A nonsense mutation is an alteration in the genetic code that prematurely halts the synthesis of an essential protein. The resulting disorder is determined by which protein cannot be expressed in its entirety and is no longer functional, such as dystrophin in Duchenne muscular dystrophy. Translarna is licensed in the European Economic Area for the treatment of nonsense mutation Duchenne muscular dystrophy in ambulatory patients aged five years and older. Translarna is an investigational new drug in the United States. The development of Translarna has been supported by grants from Cystic Fibrosis Foundation Therapeutics Inc. (the nonprofit affiliate of the Cystic Fibrosis Foundation); Muscular Dystrophy Association; FDA's Office of Orphan Products Development; National Center for Research Resources; National Heart, Lung, and Blood Institute; and Parent Project Muscular Dystrophy.
About EMA scientific advisors
The EMA scientific advisors include the Scientific Advice Working Party (SAWP) and the Scientific Advisory Group (SAG). The SAWP is a standing working party established by the CHMP with the sole remit of providing scientific advice and protocol assistance. The SAG is convened at the request of the CHMP to provide independent recommendations on scientific or technical matters relating to products under evaluation by the CHMP, or on any other scientific issue relevant to the work of the CHMP.
