8-K: European Commission Returns Translarna Decision to CHMP for Re-evaluation, PTC Therapeutics Pauses 2024 Revenue Guidance

The European Commission has decided not to adopt the negative opinion on Translarna's marketing authorization renewal and has requested a re-evaluation, leading PTC Therapeutics to pause its 2024 revenue guidance.

Summary

• The European Commission (EC) has decided not to accept the negative opinion from the Committee for Medicinal Products for Human Use (CHMP) regarding the renewal of the conditional marketing authorization for Translarna.
• The EC has returned the matter to the CHMP for re-evaluation, asking them to consider all available evidence, including patient registry data and real-world evidence.
• As a result, Translarna remains available for patients in Europe under its current marketing authorization.
• The European Medicines Agency (EMA) has invalidated the Scientific Advisory Group (SAG) meeting for Translarna held in September 2023 and subsequent procedural steps, meaning the input from the September 2023 and January 2024 meetings will not be considered in future evaluations.
• Due to the uncertainty surrounding the impact of the continued authorization on 2024 revenue, PTC Therapeutics has paused its 2024 total revenue guidance, with an update to be provided at a later date.
