Brief Summary:
This phase II trial studies how well cabozantinib and pembrolizumab work for the first-line treatment of patients with liver cancer who are not eligible for local therapy (i.e. advanced stage). Cabozantinib may stop the growth of tumor cells by blocking some cell surface receptors and signaling pathways inside the tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer. Giving cabozantinib and pembrolizumab together may work better in treating patients with advanced liver cancer compared to cabozantinib or pembrolizumab alone.
