Radiation Therapy, Arsenic Trioxide, and Temozolomide in Treating Patients With Newly Diagnosed High-Grade Glioma

• Status: Completed
• Trial end date: 2009-02-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as arsenic trioxide and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Arsenic trioxide and temozolomide may also make tumor cells more sensitive to radiation therapy. Giving radiation therapy together with combination chemotherapy may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of arsenic trioxide when given together with temozolomide and radiation therapy in treating patients with newly diagnosed high-grade glioma.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: City of Hope Medical Center
• Collaborator: National Cancer Institute (NCI)
• Treatments: Arsenic Trioxide; Dacarbazine; Temozolomide

Criteria

DISEASE CHARACTERISTICS:

• Newly diagnosed grade III or IV glioma including any of the following:

• Glioblastoma

• Anaplastic astrocytoma

• Gliosarcoma

• Anaplastic oligodendroglioma

• Anaplastic oligoastrocytoma

• Measurable or nonmeasurable disease

• No more than 5 weeks since prior brain surgery

• Recovered from surgery, post- operative infection, and other complications

• Preoperatively and postoperatively diagnostic contrast-enhanced MRI or CT scan of the brain performed prior to radiation therapy

• Patients diagnosed by stereotactic biopsy do not require the postoperative scan

PATIENT CHARACTERISTICS:

• Karnofsky performance status ≥ 60%

• Absolute neutrophil count ≥ 1,500/mm^3

• Platelet count ≥ 100,000/mm^3

• Serum creatinine ≤ 1.5 times upper limit of normal (ULN)

• Total bilirubin ≤ 2.0 mg/dL

• AST ≤ 4.0 times ULN

• No prolonged QT interval > 460 milliseconds on baseline electrocardiogram in the presence of normal serum potassium and magnesium

• No uncontrolled electrolyte imbalance (i.e., sodium < 132 mmol/L, potassium < 3.5 mEq/dL, magnesium < 1.7 mg/dL)

• No history of torsades de pointes type of ventricular arrhythmia

• Negative pregnancy test

• Not pregnant or nursing

• Fertile patients must use effective contraception

• No medical or psychiatric illness that, in the investigator's opinion, could potentially preclude the completion of study therapy

• No HIV positivity

• No active connective tissue disorders (e.g., lupus or scleroderma) that, in the investigator's opinion, may put the patient at high risk for radiation toxicity

PRIOR CONCURRENT THERAPY:

• See Disease Characteristics

• No prior brain radiotherapy or chemotherapy for brain tumor

• Concurrent corticosteroids to control cerebral edema allowed provided dose is stable or decreasing for the past 5 days

• No concurrent or plan to receive drugs that are known to prolong the QT interval

• No prior radiation to the head or neck (except for T1 glottic cancer) resulting in overlap of radiation fields
