Atezolizumab in Combination With a Multi-Kinase Inhibitor for the Treatment of Unresectable, Locally Advanced, or Metastatic Liver Cancer

This phase II trial tests whether atezolizumab in combination with a multi-kinase inhibitor (cabozantinib or lenvatinib) compared to multi-kinase inhibitor alone in treating patients with liver cancer that cannot be removed by surgery (unresectable), has spread to has spread to nearby tissue or lymph nodes (locally advanced), or has spread to other places in the body (metastatic), for which the patient has received treatment in the past (previously treated). 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. Cabozantinib and lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving atezolizumab with cabozantinib or lenvatinib may kill more tumor cells in patients with liver cancer.
