The U.S. Food and Drug Administration (FDA) has approved a new treatment option for patients with high-risk non–muscle invasive bladder cancer (NMIBC), authorizing the use of durvalumab (Imfinzi) in combination with Bacillus Calmette-Guérin (BCG) on May 28, 2026. The decision represents an expansion of immunotherapy-based treatment strategies for a disease known for its high recurrence rate and long-term management needs.
NMIBC is the most common form of bladder cancer and is characterized by tumors confined to the bladder's inner lining without invading the muscle layer. Although generally less aggressive than muscle-invasive disease, it frequently recurs after treatment and, in some cases, can progress, requiring ongoing surveillance and repeated intervention.
