Pfizer’s Sasanlimab Shows Promising Results in Phase 3 Trial for High-Risk Non-Muscle Invasive Bladder Cancer

Pfizer's Sasanlimab Success:
Pfizer's subcutaneous PD-1 blocker, sasanlimab, in combination with Bacillus Calmette-Guérin (BCG), has shown significant improvement in event-free survival (EFS) in patients with BCG-naïve, high-risk non-muscle invasive bladder cancer (NMIBC) in a Phase 3 trial24.

Clinical Significance:
The trial results indicate that sasanlimab, if approved, could be the first PD-1 inhibitor used in combination with BCG for this patient population, offering a new treatment option that could delay or reduce the need for more aggressive treatments like radical cystectomy23.

Comparison to Keytruda:
Sasanlimab's success in this specific indication distinguishes it from Merck's Keytruda, which is not indicated for use in combination with BCG for high-risk NMIBC patients who have not previously undergone BCG treatment3.

Treatment Landscape:
High-risk NMIBC has seen limited advancements in treatment options over the past three decades, making sasanlimab's results potentially practice-changing23.

Pfizer's Commitment:
The positive results from the CREST trial underscore Pfizer's leadership in genitourinary cancer research and development, highlighting the company's commitment to delivering new treatment options for bladder cancer patients2.
