Y-90 Radioembolization, Durvalumab, Tremelimumab, and Zanzalintinib for the Treatment of Unresectable and Locally-Advanced Hepatocellular Carcinoma

This phase II trial tests how well giving Y-90 radioembolization, durvalumab, tremelimumab and zanzalintinib works for the treatment of hepatocellular carcinoma that cannot be removed by surgery (unresectable) and that has spread to nearby tissue or lymph nodes (locally advanced). Y-90 radioembolization is a therapy that injects radioactive particles directly into an artery that feeds liver tumors to cut off their blood supply. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Zanzalintinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving Y-90 radioembolization, durvalumab, tremelimumab and zanzalintinib may be effective for treating unresectable and locally-advanced hepatocellular carcinoma.
