What happened

The FDA issued a 'safe to proceed' letter to Revolution Medicines, permitting the initiation of an expanded access treatment protocol (EAP) for the investigational pancreatic cancer drug daraxonrasib.

Who it affects

Revolution Medicines, clinical trial sponsors developing oncology therapeutics, and regulatory affairs and clinical operations professionals.

Why it matters

The authorization suggests that the FDA has determined the proposed protocol meets the criteria for expanded access, allowing patients with serious or life-threatening conditions to gain access to an investigational drug outside of traditional clinical trials. For the sponsor, this necessitates rigorous management of drug supply, safety reporting, and data collection under a specific treatment protocol that differs from standard clinical trial workflows.

Practical takeaway

Clinical and regulatory teams should prepare for the unique reporting requirements and supply chain logistics associated with an EAP. Ensure that pharmacovigilance systems are equipped to capture and process safety data from patients treated outside of the primary clinical trial setting.
