This trial studies the side effects of partial brain radiation therapy, temozolomide, chloroquine, and tumor treating fields therapy for the treatment of newly diagnosed glioblastoma. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as temozolomide, 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. Chloroquine is normally used to treat strains of malaria and prior preclinical and clinical data suggests that it may increase the efficacy of both radiation and tumor treating fields therapy. Tumor treating fields therapy uses electric fields tuned to specific frequencies to disrupt cell division, inhibiting tumor growth and potentially causing cancer cells to die. The purpose of this study is to determine the safety of partial brain radiation therapy, temozolomide, chloroquine, and tumor treating fields therapy in patients with gliobastoma



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.


I. To measure treatment effect via advanced magnetic resonance imaging (MRI) and alpha-[11C]methyl-L-tryptophan (AMT)-positron emission tomography (PET).


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.

Platelets >= 100,000/mm^3 (=< 21 days prior to registration)
Hemoglobin (Hgb) >= 9.0 g/dL (Note: The use of transfusion or other intervention to achieve Hgb >= 9.0 g/dL is acceptable.) (=< 21 days prior to registration)
Calculated creatinine clearance >= 30 mL/min by Cockcroft-Gault formula (=< 21 days prior to registration)
Total bilirubin =< 1.5 times upper limit of normal (ULN) (=< 21 days prior to registration)
Aspartate aminotransferase (AST)(serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT)(serum glutamate pyruvate transaminase [SGPT]) =< 1.5 times upper limit of normal (ULN) (=< 21 days prior to registration)
Female subjects of childbearing potential (i.e., those who are not postmenopausal for at least 1 year or surgically sterile by bilateral tubal ligation, bilateral oophorectomy or hysterectomy) and their male partners should practice at least one of the methods of birth control listed below during study entry, for the entire duration of the study and for at least 6 months after treatment with temozolomide and
A vasectomized male subject or a vasectomized partner of a female subject; hormonal contraceptives (oral, parenteral, or transdermal) for at least 3 months prior to study drug administration; intrauterine device (females); double-barrier method (condoms, contraceptive sponge, diaphragm or vaginal ring with spermicidal jellies or cream)
Female subjects of child-bearing potential must have a negative pregnancy test (urine
or serum) within 3 days of registration
Must voluntarily sign and date informed consent form for study participation, approved by an Independent Ethics Committee (IEC)/Institutional Review Board (IRB), prior to the initiation of any screening or study-specific procedures

Exclusion Criteria

Gliomatosis cerebri (a diffuse glioma [usually astrocytic] growth pattern consisting of exceptionally extensive infiltration of a large region of the central nervous system, with involvement of at least 3 cerebral lobes, usually with bilateral involvement of the cerebral hemispheres and/or deep grey matter, and frequent extension to the brain stem, cerebellum, and even the spinal cord.)
Recurrent glioblastoma (GBM)
Metastatic GBM
Infratentorial tumor
Prior chemotherapy or radiosensitizers for cancers of the head and neck region; note that prior chemotherapy for a different cancer is allowable, except prior temozolomide. Implanted carmustine (BCNU) wafer is allowed
Prior radiotherapy to the head or neck (except for T1 glottic cancer or nonmelanomatous skin cancer), resulting in overlap of radiation fields
Any prior therapy for glioblastoma besides surgery (intra-operative techniques to guide resection and experimental imaging techniques are allowed). BCNU wafer is allowed

Prior, concomitant, or planned concomitant treatment with bevacizumab, carmustine implant (Gliadel) wafers or other intratumoral or intracavitary anti-neoplastic therapy, or other experimental therapeutics intended to treat the tumor; the exceptions are diagnostic and operative guides to improve extent of resection or imaging studies, quality of life, biomarker, or epidemiological studies
