Cabozantinib in Treating Younger Patients With Recurrent or Refractory Solid Tumors
This phase I trial studies the side effects and best dose of cabozantinib in treating younger patients with recurrent or refractory solid tumors. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

- MTD and/or recommended phase 2 dose of cabozantinib, graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]In addition to determination of the MTD, a descriptive summary of all toxicities will be reported.
- Pharmacokinetic (PK) parameters of cabozantinib including systemic exposure and drug clearance [ Time Frame: Course 1, day 1 (pre-dose and 4 hours post dose), course 1 day 21 (+/- 2 days) (pre-dose, 2, 4, 8 and 24 hours post dose), course 3 day 1 (pre-dose) ] [ Designated as safety issue: No ]Will be summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit). PK parameters will be summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit).
- Disease response assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]Will be reported descriptively.
- Overall survival (OS) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]OS will also be assessed and summarized using the Kaplan-Meier method.

Experimental: Treatment (cabozantinib)
Patients receive cabozantinib PO QD on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

I. To estimate the maximum tolerated dose (MTD) and/or recommended Phase 2 dose of XL184 (cabozantinib) administered orally every day to children with refractory solid tumors including central nervous system (CNS) tumors.
II. To define and describe the toxicities of XL184 (cabozantinib) administered on this schedule.
III. To characterize the pharmacokinetics of XL184 (cabozantinib) in children with refractory solid tumors.
I. To preliminarily define the antitumor activity of XL184 (cabozantinib) within the confines of a Phase 1 study.
II. To assess the biologic activity of XL184 (cabozantinib). III. To assess the biomarker response (carcinoembryonic antigen [CEA] and calcitonin) in patients with medullary thyroid cancer treated with XL184.
IV. To evaluate overall survival from study entry through a five-year follow-up period.
OUTLINE: This is a dose-escalation study.
Patients receive cabozantinib orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then every 6 months for up to 60 months.
