Background:
Muscle-invasive bladder cancer occurs in the deep muscle of the bladder wall. The drug pembrolizumab uses a person s immune system to treat cancer. Researchers want to study treatment with this drug after muscle-invasive bladder cancer is removed. They want to see how it compares with standard treatment.
Objective:
To study the effects of using pembrolizumab after the removal of muscle-invasive bladder cancer.
Eligibility:
People ages 18 and older who have had surgery to remove muscle-invasive bladder cancer
Design:
Participants will be screened with:
Medical history
Physical exam
Blood tests
Scans
Participants will have a tumor sample tested for a certain protein.
Participants will be randomly assigned to a group:
Group 1 will have treatment with pembrolizumab. They will get it by vein over 30 minutes once every 3 weeks for 1 year. Then they will be monitored for another 4 years. They will have visits every few months for those 5 years.
Group 2 will have scans without treatment. They will be contacted every 3 weeks by phone to see how they are feeling. They will have a visit every 6 weeks for 1 year. Then they will have visits every few months for 5 years.
Participants can choose to join another study:
Quality of Life Study: Participants will answer questions about their physical and emotional well-being 4 times.
Sample Collections for Lab Studies or Future Studies: Participants will give blood samples 3 times. A tumor sample taken during their surgery will be stored for future studies.
Eligibility
