CHMP provides Translarna™ (ataluren) Label Update

Translarna is currently indicated for ambulatory Duchenne patients who are over two years of age; the requested extension would have allowed for the inclusion of non-ambulatory patients in the label. PTC plans to request a re-examination of the procedure within the next two weeks and expects the new examination to last approximately 4 months.

The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has completed their review of a proposed indication extension of Translarna™ (ataluren) for the treatment of patients with nonsense mutation Duchenne muscular dystrophy who are non-ambulatory. While the CHMP adopted a negative opinion of the extension, PTC Theurapeutics was informed by EMA representatives that the European Public Assessment Report (EPAR) will be updated to clarify that patients who start Translarna while ambulatory are not required to discontinue treatment after loss of ambulation.

Translarna received the annual renewal of its conditional marketing authorization in June 2019 for nonsense mutation Duchenne muscular dystrophy patients who are ambulatory and two years and over. In addition, in connection with the June 2019 renewal, PTC’s specific obligation for the submission of the results of Study 041, an ongoing clinical trial of ataluren, has been extended to September 2022.

About ataluren (Translarna™)

Translarna (ataluren), discovered and developed by PTC Therapeutics, 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, the tradename of ataluren, is licensed in the European Economic Area for the treatment of nonsense mutation Duchenne muscular dystrophy in ambulatory patients aged two years and older. Ataluren is an investigational new drug in the United States.
