Keynote B15 - EV/Pembro vs GEM/CIS in muscle-invasive bladder cancer

What is the Purpose of this Study?

We are doing this study to find out if an experimental combination of two drugs, enfortumab vedotin (EV) and pembrolizumab, is a safe and effective treatment for your cancer. EV is an approved treatment for bladder cancer, and pembrolizumab is an immunotherapy that is approved to treat other cancers.

What is the Condition Being Studied?

Muscle-Invasive Bladder Cancer

Who Can Participate in the Study?

Adults ages 18+ who:
- Are diagnosed with muscle-invasive bladder cancer
- Are eligible for radical cystectomy and pelvic lymph node dissection
- Have never received chemotherapy, immunotherapy, or radiation for bladder cancer

Age Group

What is Involved?

If you choose to join this study, you will:
- Be randomly assigned (like a coin flip) to 1 of 2 groups
-- Group A will take the study drugs, EV and pembrolizumab
-- Group B will take the chemotherapy combination of gemcitabine and cisplatin
- Have surgery to remove your bladder after about 12 weeks of drug therapy

Participants assigned to Group A will continue to take EV and pembrolizumab after surgery.
