- Brief Summary
Investigators are testing new experimental drug combinations such as the combination of vorinostat, vincristine, irinotecan, and temozolomide in the hopes of finding a drug that may be effective against tumors that have come back or that have not responded to standard therapy.
The goals of this study are:
* To find the highest safe dose of vorinostat that can be given together with vincristine, irinotecan, and temozolomide without causing severe side effects;
* To learn what kind of side effects this four drug combination can cause;
* To learn about the effects of vorinostat and the combination of vorinostat, vincristine, irinotecan, and temozolomide on specific molecules in tumor cells;
* To determine whether the combination of vorinosat, vincristine, irinotecan, and temozolomide is a beneficial treatment.
- Detailed Description
This first cycle will be used to determine whether the patient can tolerate the chemotherapeutic backbone without developing a DLT. The baseline disease evaluation will be obtained following hematologic recovery from the first cycle of chemotherapy, after which combination therapy with vorinostat will be given in subsequent cycles (2-12) w/ modifications if needed. Vorinostat dose escalation in subsequent patient cohorts will occur based on DLT to determine a MTD.

-
Organ function:
Bone marrow function:

-
Hemoglobin greater than or equal to 8 gm/dL

Patients with known bone marrow metastatic disease may enroll on the study if they have a peripheral ANC greater than or equal to 750 cells/mcL. They will not be evaluable for hematologic toxicity.
- Adequate liver function:
-
Total bilirubin less than or equal to 1.5x upper limit of normal (ULN) for age.
-
SGPT (ALT) less than or equal to 5x ULN
-
Serum albumin greater than or equal to 2 gm/dL
- Adequate renal function:
-
Creatinine clearance or glomerular filtration rate >70 ml/min/1.73 m2 or a serum creatinine based on age and gender as follows:
Age Maximum serum creatinine concentration (mg/dL) Male Female 1-<2 years 0.6 0.6 2-<6 years 0.8 0.8 6-<10 years 1 1 10-<13 years 1.2 1.2 13-<16 years 1.5 1.4 greater than or equal to 16 years 1.7 1.4 The threshold creatinine values in this table were derived from the Schwartz formula to estimate glomerular filtration rates (Schwartz et al. J. Peds. 106; 522. 1985) using child length and stature data from the CDC.
- Informed consent: All patients less than 18 years of age must sign a written informed consent. For patients <18 years of age, a parent or guardian must sign a written informed consent, unless the patient is an emancipated minor. Childhood assent, when appropriate, should be obtained as well per institutional guidelines.
- Pregnancy or breast feeding: Women who are pregnant or breast feeding will not be entered on the protocol due to the risks of fetal and teratogenic adverse events with the therapeutic agents used in the protocol therapy.
- Corticosteroid use: Patients with CNS tumors who have not been on a stable or decreasing dose of corticosteroids for the 7 days prior to the initiation of protocol therapy.
- Antineoplastic therapy: Patients receiving any other antineoplastic therapy.
- Medication allergy:
Allergy or intolerance to any of the protocol agents: vincristine, irinotecan, temozolomide, or vorinostat.
Allergy or intolerance to cephalosporins.
- Infection: Patients who have any uncontrolled infection, positive blood culture within 48 hours prior to protocol entry, or diagnosed or receiving therapy for Clostridium difficile infection.
- Patients may not have taken valproic acid or any other histone deacetylase inhibitor for at least 2 weeks prior to study enrollment.
- Children with neurofibromastosis Type 1, if being used for treatment of a low grade glioma.

Group Intervention Description Vorinostat Vorinostat The first cycle of chemotherapy will not include the experimental agent vorinostat. This first cycle will be used to determine whether the patient can tolerate the chemotherapeutic backbone without developing a DLT. Cycle 1 * Vincristine: 1.5 mg/m2/day (maximum dose 2 mg) IV Days 1 and 8 over 1-15 minutes. * Temozolomide: 125 mg/m2/day PO Days 1-5. * Irinotecan: 50 mg/m2/day IV Days 1-5 over 60 minutes. * Cefixime: 8 mg/kg/day (maximum dose 400 mg) PO. Begin 2 days prior to irinotecan therapy and continue through Day 8. Cycles 2-12 * Vincristine: 1.5 mg/m2/day (maximum dose 2 mg) IV Days 1 and 8 over 1-15 minutes. * Temozolomide: 125 mg/m2/day PO Days 1-5. * Irinotecan: 50 mg/m2/day IV Days 1-5 over 60 minutes. * Cefixime: 8 mg/kg/day (maximum dose 400 mg) PO. Begin 2 days prior to irinotecan therapy and continue through Day 8. * Vorinostat: Dose per escalation schema daily Days 1-5. * Vorinostat will not be administered during Cycle 1.
- Primary Outcome Measures
Name Time Method To determine a maximally tolerated (or optimal) dose of vorinostat 1 year A minimum of 3 evaluable patients will be entered at each dose level. If no significant dose limiting toxicity is discovered, a maximum of 3 dose levels will be evaluated. The minimum patient enrollment will be 3 patients. Many of the patients enrolled on this trial are expected to be heavily pretreated. All patients will be given a VIT only "window" to evaluate adequate bone marrow reserve to tolerate protocol therapy. We expect that at most 20% of patients will not be able to tolerate VIT or VIT with dose reduced temozolomide. A maximum of 24 patients enrolled on study is anticipated. Once the MTD has been defined, up to 6 additional patients may be enrolled to acquire additional safety data regarding this combination of agents.
- Secondary Outcome Measures
Name Time Method Overall response rate (ORR) after therapy 1 year To determine the overall response rate (ORR) of vorinostat in combination with VIT in children, adolescents, and young adults with relapsed or refractory solid tumors.
The overall (CR+PR) and best response rates with the 95% confidence intervals will be estimated based on the exact binomial distribution.
