PTC Therapeutics: European Commission has returned the TranslarnaTM Opinion to Committee for Medicinal Products for Human Use For Re-evaluation

May 23, 2024
  • European Commission decides against adoption of negative opinion
  • Translarna authorization remains active in Europe

PTC Therapeutics announced on May 20, 2024 that the European Commission (EC) has decided not to adopt the (CHMP) negative opinion of January 24, 2024 on the annual renewal of the conditional marketing authorization of TranslarnaTM (ataluren) and has returned the opinion to the CHMP for re-evaluation. As a result, Translarna remains on the market and available for patients in Europe consistent with its current marketing authorization. The EC has asked the CHMP to further consider the totality of evidence, including data from patient registries and real-world evidence, in a revised opinion.

“The maintenance of the current authorization of Translarna is a big win for boys and young men with nonsense mutation Duchenne muscular dystrophy in Europe.”

“The efficacy and safety demonstrated in clinical trials and the long-term STRIDE registry support that Translarna fills an otherwise unmet need for nmDMD patients. We look forward to working collaboratively with CHMP on next steps once they are defined.”

Matthew B. Klein, M.D., Chief Executive Officer, PTC Therapeutics

In addition, the European Medicines Agency (EMA) has informed PTC that the decision has been taken to consider the Scientific Advisory Group (SAG) meeting for Translarna held on September 5, 2023, and all the procedural steps that followed, as invalid. Furthermore, the input from the SAG meeting held in September 2023 as well as the meeting held in January 2024 will not be considered by the CHMP in any future evaluation of Translarna.

Given the inability to accurately forecast the upside impact of the continued authorization of Translarna in Europe on 2024 revenue, PTC will pause 2024 total revenue guidance at this time. Guidance will be updated at a future date.


About TranslarnaTM (ataluren)
