Prior Therapy
a. Patients must have fully recovered from the acute toxic effects of all prior anti-cancer chemotherapy i. Cytotoxic chemotherapy (including investigational agents) or biologic agents (eg. Cytokines or antibodies): At least 3 weeks after the last dose.
ii. Nitrosoureas/mitomycin C: At least 6 weeks from the last dose. iii. XRT: At least 14 days after local palliative XRT (small port); At least 150 days must have elapsed if prior TBI, craniospinal XRT or if ≥ 50% radiation of pelvis; At least 42 days must have elapsed if other substantial BM radiation. e.g. Stem cell Infusion without TBI: No evidence of active graft vs. host disease and at least 56 days must have elapsed after transplant or stem cell infusion.
Organ Function Requirements:
a. Adequate bone marrow function defined as: absolute neutrophil count (ANC ≥1000/mm3) i. Platelet count ≥ 100,000/ mm3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment) ii. Patients with bone marrow metastatic disease will not be eligible. b. Adequate renal function defined as: i. Creatinine clearance or radioisotope GFR ≥ 70mL/min/1.73 m² or a serum creatinine based on age/gender as follows:
Age Maximum Serum Creatinine (mg/dL) Male Female 2 to < 6 years 0.8 0.8 6 to < 10 years 1 1 10 to < 13 years 1.2 1.2 13 to < 16 years 1.5 1.4
≥ 16 years 1.7 1.4 The threshold creatinine values in this table were derived from the Schwartz formula for estimating GFR (Schwartz et al. J. Peds, 106:522, 1985) utilizing child length and stature data published by the CDC.
ii. Urine protein: ≤ 30 mg/dL in urinalysis or ≤ 1+ on dipstick, unless quantitative protein is < 1000 mg in a 24 hour urine sample.
c. Adequate Liver Function Defined as:
i. Bilirubin (sum of conjugated + unconjugated) ≤ 1.5 x upper limit of normal (ULN) for age ii. SGPT (ALT) ≤ 110 U/L. For the purpose of this study, the ULN for SGPT is 45 U/L.
iii. Serum albumin ≥ 2.8 g/dL. d. Adequate coagulation status defined as: PT and INR ≤ 1.5x ULN e. Adequate pancreatic function defined as: Serum amylase and lipase ≤ 1.5 x ULN f. Adequate blood pressure control defined as: A blood pressure (BP) ≤ the 95th percentile for age, height and gender (Appendix II) despite optimal antihypertensive treatment within 7 days of the first dose of the study treatment. Please note that 3 serial blood pressures should be obtained and averaged to determine baseline BP.
g. Central nervous system function defined as: Patients with seizure disorder may be enrolled if receiving non-enzyme inducing anticonvulsants and well controlled. See Appendix III for a list of recommended non-enzyme inducing anticonvulsants.
h. Adequate cardiac function defined as: i. No history of congenital QTc syndrome, NYHA Class III or IV congestive heart failure (CHF) ii. No clinical significant cardiac arrhythmias, stroke or myocardial infarction within 6 months prior to enrollment iii. QTc
≤ 480 msec. Note: One ECG must be performed for eligibility determination. If the QTc is > 480 msec, two additional ECGs must be performed and the average of the three ECGs will be used to determine eligibility. Patients with Grade 1 prolonged QTc (450-480 msec) at the time of study enrollment should have correctable causes of prolonged QTc addressed if possible (i.e. electrolytes, medications). See Appendix IV for a list of drugs that prolong QTc.
- Informed consent: All patients and/or their parents or legally authorized representatives must sign a written informed consent. Assent, when appropriate will be obtained according to institutional guidelines.
- Archival tumor tissue slides must be sent or available, except for patients with intrinsic pontine glioma meeting the remainder of the inclusion criteria.
Exclusion Criteria
- Pregnancy or Breast-Feeding: Pregnant or breast-feeding women will not be entered on this study due to risks of fetal and teratogentic adverse events as seen in animal/human studies. Pregnancy tests must be obtained in girls who are post-menarchal. Males or females of reproductive potential may not participate unless they have agreed to use two methods of birth control- a medically accepted barrier method of contraceptive method (e.g., male or female condom) and a second effective method of birth control- during protocol therapy and for at least 4 months after the last dose of cabozantinib. Abstinence is an acceptable method of birth control.
Concomitant Medications:
- Corticosteroids: Patients receiving corticosteroids who have not been on a stable or decreasing dose of corticosteroid for at least 7 days prior to enrollment are not eligible.
- Investigational drugs: Patients who are currently receiving another investigational drug are not eligible.
- Anti-cancer agents: patients who are currently receiving other anti-cancer agents are not eligible.
- CYP3A4 active agents: Patients must not be receiving any of the following potent CYP3A4 inducers or inhibitors: erythromycin, clarithromycin, ketoconazole, azithromycin, itraconazole, grapefruit juice or St. John's wort. A list of other known CYP3A4 inducers and inhibitors that should be discontinued prior to initiation of protocol therapy and should be avoided during study therapy if reasonable alternatives exist is included in Appendix V.
- Patients who are receiving systemic therapeutic treatment anticoagulation are not eligible. Patients receiving prophylactic systemic anticoagulation will be allowed with heparin or LMWH as long as eligibility PT/INR requirements are met. Concomitant anticoagulation with oral anticoagulations (e.g. warfarin, direct thrombin and Factor Xa inhibitors) or platelet inhibitors (eg. Clopidogrel) are not allowed.
- Enzyme-inducing anticonvulsants: Patients must not have received enzyme-inducing anticonvulsants within 14 days prior to enrollment (See Appendix III for a list of unacceptable enzyme inducing anticonvulsants).

Measure Description |
Time Frame |
---|---|---|
Number of Participants With Disease Response
Time Frame: 6 months
|
To assess the number of participants with best response of CR, PR, SD or PD. Response criteria are assessed based on the product of the longest diameter and its longest perpendicular diameter. Complete response (CR): Disappearance of all target lesions Partial response (PR): ≥50% decrease in the sum of the products of the two perpendicular diameters of all target lesions (up to 5), taking as reference the initial baseline measurements Stable disease (SD): Neither sufficient decrease in the sum of the products of the two perpendicular diameters of all target lesions to qualify for PR, nor sufficient increase in a single target lesion to qualify for PD. Progressive Disease (PD): The appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions. |
