Cabozantinib-S-Malate in Treating Younger Patients With Recurrent, Refractory, or Newly Diagnosed Sarcomas, Wilms Tumor, or Other Rare Tumors

Status: Recruiting
Phase:
DFCI Protocol ID: 17-716

This phase II trial studies how well cabozantinib-s-malate works in treating younger patients with sarcomas, Wilms tumor, or other rare tumors that have come back, do not respond to therapy, or are newly diagnosed. Cabozantinib-s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for tumor growth and tumor blood vessel growth.
