Imfinzi sBLA Gets Priority Review for Bladder Cancer

FDA has accepted for priority review an AstraZeneca supplemental BLA for Imfinzi (durvalumab) in combination with enfortumab vedotin (EV) for treating patients with muscle-invasive bladder cancer (MIBC) who are ineligible for or have declined cisplatin-based chemotherapy. The agency set a user fee review action target date for upcoming fourth quarter.

The sBLA is based on results from the VOLGA Phase 3 trial, according to the company. “In a planned interim analysis, perioperative treatment with Imfinzi in combination with neoadjuvant EV demonstrated statistically significant and clinically meaningful improvements in event-free survival (EFS) and overall survival (OS) versus radical cystectomy (surgery to remove the bladder) with or without approved adjuvant treatment,” it says.

Durvalumab is a programmed death ligand-1, or PD-L1, blocking antibody already approved for several cancer indications, including lung and liver cancers. The prescribing information for Imfinzi includes warnings about immune-mediated adverse reactions, infusion-related reactions, complications following allogeneic hematopoietic stem cell transplantation and embryo-fetal toxicity.
