What is the purpose of this trial?

This phase II trial studies how well cabozantinib and temozolomide work in treating patients with leiomyosarcoma or other soft tissue sarcoma that cannot be removed by surgery (unresectable) or has spread to other places in the body (metastatic). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving cabozantinib and temozolomide may work better than either one alone in treating patients with leiomyosarcoma or other soft tissue sarcoma. Cabozantinib is an investigational drug, which means that it has not been approved by the United States (US) Food and Drug Administration (FDA) or any other regulatory agencies for sale or use by the public for the indication under investigation in this study.

What Are the Treatments Tested in This Trial?

Interventions

• Cabozantinib
• Temozolomide

Trial Overview The study tests the combination of cabozantinib (an enzyme blocker) and temozolomide (a chemotherapy drug) on tumor growth in leiomyosarcoma or other soft tissue sarcomas. The goal is to see if this combo works better than either drug alone.

How Is the Trial Designed?

Group I: Treatment (cabozantinib, temozolomide) Experimental Treatment 4 Interventions

Patients receive cabozantinib PO QD on days 1-28 and temozolomide PO QD on days 1-5. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
