Radiation Therapy, Temozolomide, and Erlotinib in Treating Patients With Newly Diagnosed Glioblastoma Multiforme
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving radiation therapy together with temozolomide and erlotinib after surgery may kill any remaining tumor cells.
PURPOSE: This phase II trial is studying how well giving radiation therapy together with temozolomide and erlotinib works in treating patients with newly diagnosed glioblastoma multiforme.

|Experimental: Radiation Therapy, Temozolomide, and Erlotinib||
Drug: erlotinib hydrochloride
Erlotinib is available as 25 mg, 100 mg, and 150 mg tablets. It should be administered orally once daily at the prescribed dose specified in the clinical study protocol per dose escalation schema. Preferably, erlotinib should be taken in the morning with up to 200 mL of water at least 1 hour before or 2 hours after a meal.
Other Name: TarcevaDrug: temozolomide
TMZ is supplied in white opaque, preservative-free, two piece hard gelatin capsules of the following sizes: 100mg capsules, 20mg capsules, and 5mg capsules. TMZ will be a once a day orally administered (75 mg/m2 x BSA x 42 days)set of capsules taken at least two hours after and one hour before a meal.
Other Name: TemodarRadiation: radiation therapy
Concomitant focal RT will be delivered once daily at 2 Gy per fraction, 5 d/wk, for a total of 60 Gy. (6 weeks) as mentioned in therapeutic modalities.
Other Name: RT
- Determine the progression-free survival and overall survival of patients with newly diagnosed glioblastoma multiforme treated with adjuvant radiotherapy, temozolomide, and erlotinib hydrochloride.
- Evaluate the toxicity of this regimen in these patients.
OUTLINE: This is a non-randomized study.
Patients receive oral temozolomide once daily on days 1-42 and undergo concurrent radiotherapy once daily on days 1-5, 8-12, 15-19, 22-26, 29-33, and 36-40. Four weeks after completion of radiotherapy and temozolomide, patients receive oral temozolomide once daily on days 1-5. Treatment with temozolomide repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. Patients also receive oral erlotinib hydrochloride once daily beginning on day 1 of radiotherapy and continuing in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically.
PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.
