The purpose of this study is to compare any good and bad effects of using a drug called MK-3475 (pembrolizumab) after the removal of your muscle invasive bladder cancer. MK-3475 is a drug that uses a person’s own immune system to treat cancer. This study will allow researchers to know whether treatment with MK-3475 is better, the same, or worse than the usual approach. To be better, the MK3475 should increase life by 9 months or more, compared to observation alone. The use of MK-3475 could prevent your cancer from returning but it could also cause side effects. This immunotherapy drug, MK-3475, is already FDA-approved for use in other types of cancers, but for your type of cancer it is considered experimental.
