Combination Chemotherapy With or Without Sodium Thiosulfate in Preventing Low Platelet Count While Treating Patients With Malignant Brain Tumors

Brief Summary
This randomized phase II trial studies how well giving combination chemotherapy with or without sodium thiosulfate works in preventing low platelet count while treating patients with malignant brain tumors. Drugs used in chemotherapy, such as carboplatin, cyclophosphamide, and etoposide phosphate, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Sodium thiosulfate may prevent low platelet counts in patients receiving chemotherapy. It is not yet known whether combination chemotherapy is more effective with or without sodium thiosulfate in preventing low platelet count during treatment for brain tumors.

Outcome Measures
Primary Outcomes (1)
Rate of platelet toxicities (i.e. platelet count less than 20,000), graded according to the National Cancer Institute Common Toxicity Criteria version 3.0
The Pearson chi-square test will be the primary test to compare rates.
Up to 4 weeks after completion of study treatment
Secondary Outcomes (8)
Number of dose reductions and transfusions due to platelet toxicity
Up to 30 days after completion of study treatment
Tumor response (complete response + partial response + stable disease) assessed by neurologic exams, radiographic studies, and steroid dose
Up to 10 years
Time to response
Up to 10 years
Time to disease progression
Up to 10 years
Granulocyte count
Up to 30 days after completion of study treatment
- +3 more secondary outcomes
Study Arms (2)
Arm I (combination chemotherapy)
EXPERIMENTALPatients receive cyclophosphamide IV, etoposide phosphate IV, and carboplatin IA over 10 minutes. Treatment repeats every 4 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity.
Arm II (combination chemotherapy, sodium thiosulfate)
EXPERIMENTALPatients receive cyclophosphamide IV, etoposide phosphate IV, and carboplatin IA as in Arm I. Patients also receive sodium thiosulfate IV over 15 minutes 4 and 8 hours later. Treatment repeats every 4 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria
You may qualify if:
- Subjects with histologically confirmed high-grade glioma are eligible; diagnosis of high-grade glioma will be made on the basis of needle biopsy, open biopsy, or surgical resection
- Subjects may have had prior focal or systemic radiation or chemotherapy; at least 14 days must have elapsed since radiation treatment and 28 days since prior chemotherapy
- Performance status (Eastern Cooperative Oncology Group \[ECOG\]) must be less than or equal to 2 (Karnofsky greater than or equal to 50)
- White blood cell count \>= 2.5 x 10\^3/mm\^3
- Absolute granulocyte count \>= 1.2 x 10\^3/mm\^3
- Platelets \>= 100 x 10\^3/mm\^3
- Creatinine \< 1.8
- Bilirubin \< 2.0
- Baseline aspartate aminotransferase (AST)/alanine aminotransferase (ALT) serum glutamic oxaloacetic transaminase (SGOT)/serum glutamate pyruvate transaminase (SGPT) must be \< 2.5 x institutional upper limits of normal
- Subject (or legal guardian) must sign a written informed consent in accordance with institutional guidelines
- Sexually active women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; or abstinence) prior to study treatment and for the duration of study treatment; should a female become pregnant or suspect she is pregnant while participating in this study, she should inform the investigator
You may not qualify if:
- Subjects with rapidly progressing central nervous system (CNS) disease with associated neurological deterioration
- Subjects with uncontrolled (over the last 30 days) clinically significant confounding medical conditions such as congestive heart failure
- Subjects who are pregnant, have a positive serum human chorionic gonadotropin (hCG) or are lactating
- Subjects who have contraindications to carboplatin, cyclophosphamide, etoposide phosphate, or sodium thiosulfate
