Cabozantinib (C) has been combined successfully with either PD-1 or CTLA-4 inhibition in cancer clinical trials. In vitro, cabozantinib has shown relevant activity in inhibiting the growth and viability of soft tissue sarcoma, GIST, osteosarcoma, and Ewing sarcoma tumor cell lines. Cabozantinib also promoted the regression of GIST in various murine xenografts, including imatinib-resistant models. More than 10 prospective trials with cabozantinib that included patients with sarcomas have been completed or are currently ongoing. Clinical activity with cabozantinib has been recently reported in phase 2 clinical trials for patients with GIST and for patients with osteosarcoma or Ewing sarcoma.
