Partial Brain RT, Temozolomide, Chloroquine, and TTF Therapy for the Treatment of Newly Diagnosed Glioblastoma

PRIMARY OBJECTIVE: I. To determine the safety of partial brain radiation therapy plus temozolomide and chloroquine followed by tumor treating fields (TTFs) plus temozolomide and chloroquine, specifically grade 3 or higher dermatitis within the first 3 months of the adjuvant therapy phase. SECONDARY OBJECTIVE: I. To measure treatment effect via advanced magnetic resonance imaging (MRI) and alpha-\[11C\]methyl-L-tryptophan (AMT)-positron emission tomography (PET). OUTLINE: Patients undergo 30 fractions of 3-dimensional conformal radiation therapy (3D CRT) or intensity-modulated radiation therapy (IMRT) and receive temozolomide orally (PO) and chloroquine PO daily from day 1 for the duration of radiation therapy up to day 49. Treatment continues in the absence of disease progression or unacceptable toxicity. ADJUVANT TREATMENT: Beginning 4 weeks after the last day of radiation therapy, patients receive temozolomide PO once daily (QD) on days 1-5 and chloroquine PO daily on days 1-28. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients demonstrating continued benefit may continue to receive temozolomide and chloroquine for up to 12 cycles. Patients also undergo TTF therapy over 18 hours or longer per day. After completion of study treatment, patients are followed up monthly for 3 months.
