Intravesical BCG vs GEMDOCE in NMIBC (BRIDGE)

This study is being done to answer the following question: Can we lower the chance of your bladder cancer growing or spreading by using one type of chemotherapy instilled in the bladder, Gemcitabine and Docetaxel, instead of the usual BCG therapy? We are doing this study because we want to find out if this approach is better or worse than the usual approach for your bladder cancer. The usual approach is defined as care most people get for bladder cancer.
