Cabozantinib and Pembrolizumab for the First-Line Treatment of Advanced Liver Cancer

NCT04442581

Description:

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.

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.

Giving cabozantinib and pembrolizumab together may work better in treating patients with advanced liver cancer compared to cabozantinib or pembrolizumab alone.

Detailed Description

      OUTLINE:

      Patients receive cabozantinib S-malate orally (PO) once daily (QD) on days 1-21 and
      pembrolizumab intravenously (IV) over 30 minutes on day 1. Cycles repeat every 21 days for up
      to 2 years in the absence of disease progression or unacceptable toxicity. Disease assessment
      by imaging will be performed every 9 weeks.
