- Additional Requirements
- Information Transparency: Drug labeling for accelerated approval products must clearly disclose limitations, uncertainties about anticipated clinical benefits, and that use of the accelerated approval pathway. This ensures transparency and helps patients understand potential risks and benefits.
- Marketing and Advertising Integrity: All promotional materials must undergo FDA review to ensure accuracy and to prevent misleading claims, safeguarding patients and healthcare providers from misinformation.
- Progress Updates on Confirmatory Trials: Sponsors must regularly report on the status of confirmatory trials to ensure timely completion.
- Withdrawal of Accelerated Approval:
FDA may use expedited procedures to withdraw accelerated approval of a drug if confirmatory trials fail, are delayed, safety or efficacy issues arise, or misleading promotional materials are shared. The withdrawal process involves notifying sponsors, explaining the rationale, gathering public comments, and consulting advisory committees. A summary of public comments and FDA responses is published online for transparency.
Conclusion
The Accelerated Approval program accelerates drug reviews for serious or life-threatening conditions by utilizing surrogate or intermediate clinical endpoints. It requires confirmatory trials to validate benefits, including a withdrawal mechanism to manage risks, and encourages collaboration between FDA and sponsors. The guidance emphasizes scientific rigor, external consultation, and continuous refinement to ensure effective and safe drug development.
