RATIONALE: 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving arsenic trioxide and temozolomide together with radiation therapy after surgery may kill any remaining tumor cells.
PURPOSE: This phase I/II trial is studying the side effects and best dose of arsenic trioxide and temozolomide when given together with radiation therapy and to see how well they work in treating patients with malignant glioma that has been removed by surgery.
|Condition or disease||Intervention/treatment||Phase|
|Brain and Central Nervous System Tumors||Drug: arsenic trioxide Drug: temozolomide Radiation: radiation therapy||Phase 1 Phase 2|
- Determine the maximum tolerated dose (MTD) of arsenic trioxide and temozolomide when combined with radiotherapy in patients with resected supratentorial malignant glioma. (Phase I)
- Determine the toxicity of this regimen in these patients. (Phase I)
- Determine the 6- and 12-month progression-free survival of patients treated with this regimen once an MTD is reached. (Phase II)
- Determine the radiographic response for patients treated with the above regimen. (Phase II)
- Determine the safety of this regimen in these patients. (Phase II)
OUTLINE: This is a phase I, dose-escalation study of arsenic trioxide and temozolomide followed by a phase II study.
- Phase I: Patients undergo radiotherapy once daily 5 days a week and receive oral temozolomide once daily for approximately 6½ weeks. Patients also receive arsenic trioxide IV over 1-4 hours once daily, 5 days a week in week 1 and then twice a week in weeks 2-7. Beginning within 3-5 weeks after completion of radiotherapy, patients receive oral temozolomide once daily on days 1-5. Treatment with temozolomide repeats every 28 days for up to 1 year in the absence of disease progression and unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of arsenic trioxide and temozolomide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 1 of 3 or 2 of 6 patients experience dose-limiting toxicity.
- Phase II: Patients undergo radiotherapy and receive arsenic trioxide and temozolomide as in phase I at the MTD. Patients then receive temozolomide as in phase I for up to 1 year in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically for 1 year.
PROJECTED ACCRUAL: A total of 12-18 patients will be accrued for the phase I portion of this study. A total of 25 patients will be accrued for the phase II portion of this study.

Experimental: Radiation + temozolomide and arsenic trioxide
Radiation therapy followed by the combination of temozolomide and arsenic trioxide at the maximum tolerated dose determined in phase 1
Drug: arsenic trioxide
Arsenic trioxide administered intravenously at a dose of 0.20mg/kg Daily x 5 week then twice per week
Temozolomide administered orally once per day 1 hour prior to radiation therapy at a dose of 75 mg/m2 x 42 days; at a dose of 200mg/m2 for 5 days every cycle (1 cycle = 28 days) after radiation therapy
Radiation: radiation therapy
All patients will receive 5940-6120 cGy of radiation therapy as 28-33 treatments/fractions (180-200 cGy/treatment) depending on whether they receive standard 3-D conformal radiation therapy or intensity modulated radiation therapy.
- Maximum tolerated dose of arsenic trioxide and temozolomide in combination with radiotherapy [ Time Frame: Toxicity evaluated prior to each treatment cycle ]Escalating doses of study drug until dose limiting toxicities are observed.
- Collect data on the toxicity of arsenic and temozolomide during radiation therapy [ Time Frame: Toxicity evaluated prior to each treatment cycle ]Toxicity of this drug combination during radiation therapy will be assessed.
- Assess serum biomarkers and correlate with tumor tissue [ Time Frame: At baseline, during radiation therapy, and prior to each cycle of chemotherapy ]Blood will be drawn at baseline, during radiation therapy, and prior to each cycle of chemotherapy to assess serum biomarkers and correlate with tumor tissue.
- Determine progression free survival at 6 and 12 months [ Time Frame: At 6 and 12 months after beginning chemotherapy ]Patients will undergo an MRI and neurological evaluation every 6 months while on chemotherapy.
- Determine time to disease progression [ Time Frame: At 6 and 12 months after beginning chemotherapy ]Disease status will be assessed by MRI and neurological examination every 6 months until disease progression.
- To determine overall survival [ Time Frame: Every 6 months while on treatment ]Survival status will be evaluated every 6 months while on treatment.
- To determine radiographic response to study regimen [ Time Frame: Every 6 months while on treatment ]Radiographic response will be assessed by MRI every 6 months while on treatment
- To collect safety data during the radiation therapy phase [ Time Frame: Weekly during radiation therapy ]EKG's will be done once per week and labs twice per week during radiation therapy phase to evaluate safety data.
- To evaluate a potential surrogate marker for outcomes [ Time Frame: At baseline, before and after radiation therapy, and every 2 cycles during chemotherapy ]Blood will be drawn to analyze methylation patterns as a surrogate marker for outcomes at baseline, before and after radiation therapy, and every 2 cycles during chemotherapy.
