Clinical summary
Summary
Eligible patients will be randomised into one of three Arms (A, B or C). In Arm A, patients will receive atezolizumab followed by tiragolumab. In Arm B, patients will receive atezolizumab followed by tiragolumab matching placebo. And, in Arm C, patients will receive matching placebos for both tiragolumab and atezolizumab.
