Purpose

The purpose of this study is to compare any good and bad effects the study drug atezolizumab has on the cancer when combined with the standard chemotherapy drugs gemcitabine and cisplatin (or GC) in two different dosing schedules: chemotherapy (GC) before atezolizumab vs. GC after atezolizumab.

Then patient will receive combined atezolizumab and Gemcitabine and Cisplatin for 6 cycles. All 8 treatment cycles will take approximately 24 weeks. If carboplatin is substituted for cisplatin, eGFR for dosing may be calculated by institutional standard formulas, at the discretion of the treating investigator.
