Description

Summary

This study will evaluate the efficacy and safety of atezolizumab with bevacizumab in combination with cisplatin and gemcitabine(CisGem), compared with atezolizumab in combination with CisGem, in participants with advanced biliary tract cancer (BTC) who have not received prior systemic therapy. Treatment will consist of a chemotherapy combination phase followed by a cancer immunotherapy (CIT)/placebo phase.
