Mean log2 (Fold Change of CD3+ T-Cell Count/µm2) Over TimePrimary· Up to 1 year
The immunologic effect MPDL3280A activity within bladder tissue will be measured by a change in the Cluster of differentiation 3 positive (CD3+) T cell count/µm2 between pretreatment biopsy and cystectomy tissue following MPDL3280A infusions. For each cohort, the mean of the log2 of ratio of post-treatment vs. pre-treatment counts with 95% confidence intervals will be reported.

This phase II trial studies the best dose of atezolizumab in treating patients with bladder cancer that has not spread to other places in the body. Immunotherapy with monoclonal antibodies may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
