Industry Context

This announcement highlights the challenges in obtaining and maintaining regulatory approvals for rare disease treatments, particularly when real-world evidence is a key factor in the decision-making process. It also underscores the importance of ongoing dialogue with regulatory bodies to ensure patient access to needed therapies.

Comparison to Industry Standards

• The situation with Translarna is not unique, as many pharmaceutical companies face challenges in securing and maintaining regulatory approvals, especially for rare disease treatments.
• Companies like Sarepta Therapeutics, which also focuses on Duchenne muscular dystrophy, have faced similar regulatory hurdles with their therapies.
• The reliance on real-world evidence, as seen in the STRIDE study, is becoming increasingly important in regulatory decision-making, but its acceptance varies across different regulatory bodies.
• The re-examination process is a standard procedure in the European regulatory framework, and PTC's approach is consistent with industry practices in such situations.

Stakeholder Impact

• Shareholders may experience a negative impact due to the uncertainty surrounding Translarna's future in Europe.
• Patients with nmDMD and their families may face uncertainty regarding continued access to Translarna.
• Employees of PTC may be affected by the potential impact on the company's revenue and operations.
• The outcome of the re-examination process will impact the company's future strategy and financial performance.

Next Steps

• PTC will submit a request for re-examination of the CHMP's opinion.
• The company will continue to engage with the European Medicines Agency (EMA) throughout the re-examination process.
• PTC will monitor the outcome of the re-examination procedure and subsequent EC ratification.
