Study Summary

This randomized phase II trial studies how well atezolizumab with or without cobimetinib works in treating patients with bile duct cancer that has spread to other places in the body (metastatic) and cannot be removed by surgery (unresectable) or gallbladder cancer. 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.

Primary Outcome

PFS within each treatment arm will be summarized descriptively and compared between groups, under the assumption of Cox proportional hazards, using the stratified log-rank test to account for tumor site. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
