A Study of Vincristine, Escalating Doses of Irinotecan, Temozolomide and Bevacizumab (Vit-b) in Pediatric and Adolescent Patients With Recurrent or Refractory Solid Tumors of Non-hematopoietic Origin (VIT-B)

Inclusion Criteria:

• Age: Patients must be > 12 months and < 21 years of age at the time of study entry.
• Weight: Patient must be more than or equal to 10 Kilograms.

Histological Diagnosis:

• Patients must have had histological verification of the malignancy at some time prior to study entry.
• All solid tumors are eligible with the exclusion of lymphomas. For patients with neuroblastoma, diagnosis based on elevated catecholamines in the urine and tumor cells on bone marrow aspirates/biopsies is acceptable.
• For patients with germ cell tumors, diagnosis based on elevated tumor markers (serum alpha fetoprotein and/or serum beta human chorionic gonadotropin) and radiographic evidence of disease is acceptable.

Disease Status:

• Disease must have failed standard therapy (therapies) or be a disease for which no standard therapy exists.
• Patient with stable disease on other therapies are not eligible.

Performance Level:

• Karnofsky > 50% for patients >16 years of age and Lansky > 50 for children < 16 years of age (Appendix I).
• Life Expectancy: Must be > 8 weeks.

Exclusion Criteria:

• Patients who have received bevacizumab and/or Irinotecan previously are ineligible. Non brain tumor patients who have previously received Temozolomide are ineligible.
• Pregnancy or Breast-Feeding: Pregnant patients are ineligible for this study due to the known teratogenic effects of the cytotoxic agents. Pregnancy tests must be obtained in females of childbearing potential prior to enrollment.
• Lactating women must agree not to breast-feed.
• Males or females of reproductive age may not participate unless they have agreed to use an effective contraceptive method.
• Patients Who Have an Uncontrolled Infection will not be eligible for enrollment until all infections are under control.
• Clinically Significant Unrelated Systemic Illness: Patients with serious infections or significant pulmonary, hepatic, renal, or other end-organ dysfunction which in the judgment of the Principal or Co-Investigators would compromise the patient's ability to tolerate prescribed chemotherapy or are likely to interfere with the study procedures or results will not be eligible.
