NCT06156410 | RECRUITING | Ewing Sarcoma

Cabozantinib With Ifosfamide in Relapsed/Refractory Sarcomas
Sponsor:

Children's Hospital of Philadelphia

Brief Summary:

The purpose of this study is to better understand how safe and effective the drug cabozantinib in combination with high-dose ifosfamide is in the treatment of children and adults with relapsed/refractory sarcomas.

Condition or disease

Ewing Sarcoma

Osteosarcoma

Sarcomas

Intervention/treatment

Cabozantinib

Phase

PHASE1

Detailed Description:

In this study, the investigators will test the activity of cabozantinib in combination with high-dose ifosfamide as targeted therapy for relapsed/refractory sarcomas. Cabozantinib has been shown to inhibit multiple tyrosine kinases, including potent inhibition of kinases, MET and VEGFR2. Therefore, the goal of this study is to see if Cabozantinib can be used to inhibit MET and VEGFR2, or other tyrosine kinases to drive tumor responses in patients.
