Melanoma Clinical Trial
Cabozantinib S-Malate in Treating Younger Patients With Recurrent or Refractory Solid Tumors
This phase I trial studies the side effects and best dose of cabozantinib S-malate in treating younger patients with solid tumors that have come back or no longer respond to treatment. Cabozantinib S-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
I. To estimate the maximum tolerated dose (MTD) and/or recommended phase 2 dose of XL184 (cabozantinib) (cabozantinib S-malate) administered orally 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. (Complete as of 4/16/2014)
Patients receive cabozantinib S-malate orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Hematopoietic growth factors: at least 14 days after the last dose of a long-acting growth factor (e.g. Neulasta) or 7 days for short-acting growth factor; for agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur; the duration of this interval must be discussed with the study chair
Biologic (anti-neoplastic agent): at least 7 days after the last dose of a biologic agent; for agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur; the duration of this interval must be discussed with the study chair
Immunotherapy: at least 42 days after the completion of any type of immunotherapy, e.g. tumor vaccines
Monoclonal antibodies: at least 3 half-lives of the antibody after the last dose of a monoclonal antibody
Radiation therapy (XRT): at least 14 days after local palliative XRT (small port); at least 150 days must have elapsed if prior total-body irradiation (TBI), craniospinal XRT or if >= 50% radiation of pelvis; at least 42 days must have elapsed if other substantial bone marrow (BM) radiation

Peripheral absolute neutrophil count (ANC) >= 1000/mm^3
Platelet count >= 100,000/mm^3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment)
Patients with known bone marrow metastatic disease will be eligible for study provided they meet the blood counts (may receive transfusions provided they are not known to be refractory to red cell or platelet transfusions); these patients will not be evaluable for hematologic toxicity; at least 5 of every cohort of 6 patients with a solid tumor must be evaluable for hematologic toxicity in the dose-escalation part of the study; if dose-limiting hematologic toxicity is observed, all subsequent patients enrolled must be evaluable for hematologic toxicity
