Imfinzi Demonstrates Significant Survival Benefit in Muscle-Invasive Bladder Cancer
• The NIAGARA trial showed that adding Imfinzi (durvalumab) to neoadjuvant chemotherapy significantly improved event-free survival (EFS) and overall survival (OS) in patients with muscle-invasive bladder cancer (MIBC).
• The Imfinzi regimen reduced the risk of death by 25% and improved EFS by 32%, with 82% of patients alive at 24 months compared to 75% in the control group.
• The study's results, presented at ESMO, were described as practice-changing, with a manageable toxicity profile, potentially transforming the standard of care for MIBC patients.
• AstraZeneca is considering filing the NIAGARA data with the FDA, while the agency previously raised concerns about peri-operative immunotherapy regimens in resectable cancers.
