      Trial Summary

      This is a Phase III, multicenter, open-label, three-arm, randomized study in participants with unresectable locally advanced or metastatic colorectal cancer (CRC) who have received at least two prior regimens of cytotoxic chemotherapy for metastatic disease. The study compares regorafenib, a standard of care therapy in this setting, to cobimetinib plus atezolizumab and atezolizumab monotherapy.

      • Women of childbearing potential must agree to appropriately use an effective form of contraception (failure rate of less than [<] 1 percent [%] per year) during the treatment period, within 5 months after the last dose of atezolizumab, and within 3 months after the last dose of cobimetinib and regorafenib
      • Men must agree not to donate sperm or have intercourse with a female partner without using appropriate barrier contraception during the treatment period and for 3 months after the last dose of either cobimetinib or regorafenib
