Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cobimetinib is used in patients whose cancer has a mutated (changed) form of a gene called BRAF. It is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Giving atezolizumab with cobimetinib may work better at treating patients with bile duct and gallbladder cancer.", 'detailedDescription': 'PRIMARY OBJECTIVE:\n\nI. To assess the progression free survival (PFS) of patients receiving atezolizumab monotherapy and cobimetinib in combination with atezolizumab for unresectable cholangiocarcinoma.\n\nSECONDARY OBJECTIVES:\n\nI. To assess the overall survival (OS) of patients receiving cobimetinib in combination with atezolizumab and atezolizumab monotherapy for unresectable cholangiocarcinoma.\n\nII. To determine the objective response rate (ORR), defined as complete plus partial response, of cobimetinib in combination with atezolizumab and atezolizumab monotherapy in patients with unresectable cholangiocarcinoma.\n\nIII. To assess the safety and tolerability of cobimetinib in combination with atezolizumab and atezolizumab monotherapy in patients with unresectable cholangiocarcinoma.\n\nIV. To determine the relationship between PD-L1 expression in tumor at baseline and on treatment, and response to treatment.\n\nCORRELATIVE OBJECTIVES:\n\nI. To determine the effect of cobimetinib on CD8+ T cell infiltration in tumor. II. To determine the effect of cobimetinib on T cell subpopulations systemically and in tumor, PD-1/PD-L1 expression on tumor, and MHC 1/2 expression.\n\nIII. To determine the effect of cobimetinib on markers of immune exhaustion and pro-apoptotic factors in CD8+ effector T cells.\n\nIV. To explore the effect of cobimetinib on local and systemic immune activation pathways and immune suppressive pathways through expression profiling.\n\nOUTLINE: Patients are randomized to 1 of 2 arms.\n\nARM A: Patients receive atezolizumab intravenously (IV) over 30-60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
