• - Is able to have magnetic resonance imaging (MRI) with contrast of the brain.

• - All subjects must be able to comprehend and sign a written informed consent document.

If the subject can comprehend the informed consent but is unable to sign, a LAR may sign the written informed consent document.

Exclusion Criteria:

• - Infratentorial disease (defined as glioblastoma [GBM] derived from cerebellum or brainstem) - Implanted pacemaker, defibrillator or deep brain stimulator, or documented clinically significant arrhythmias.

• - A skull defect (such as, missing bone with no replacement) - Women of childbearing potential who are pregnant or breastfeeding.

• - Prior radiation treatment to the brain.

• - Prior treatment with temozolomide.

• - Known hypersensitivity to conductive hydrogels like the gel used on electrocardiogram (ECG) stickers or transcutaneous electrical nerve stimulation (TENS) electrodes.

- Known active collagen vascular disease

PRIMARY OBJECTIVES:

• I. To evaluate the safety and toxicity of combination chemoradiotherapy with NovoTTF-200A device (Optune) treatment in newly diagnosed glioblastoma.

SECONDARY OBJECTIVES:

• I. To determine the median progression-free survival of patients with newly diagnosed glioblastoma treated with radiotherapy with concurrent and adjuvant temozolomide plus Optune.

• II. To evaluate the median overall survival, 1-year overall survival, and event-free survival.

• III. Collect tumor O(6)-Methylguanine-DNA-methyltransferase (MGMT) methylation status and isocitrate dehydrogenase (IDH) mutation status.

• IV. To evaluate the level of circulating tumor deoxyribonucleic acid (DNA) in glioblastoma patient serum during treatment.

• V. To evaluate the quality of life of patients treated with radiotherapy with concurrent and adjuvant temozolomide plus Optune.

Arms

Experimental: Treatment (temozolomide, radiation, NovoTTF-200A device)

Participants receive temozolomide PO QD starting day 1 to the end of radiation therapy and undergo 30 fractions of radiation therapy over 15-20 minutes each, 5 days a week (Monday-Friday) for 6 weeks. Beginning day 1 of radiation therapy, participants undergo tumor treatment fields therapy using NovoTTF-200A device over 18 hours or more daily in the absence of disease progression or unacceptable toxicity. Beginning 28 days after the last dose of radiation therapy, participants receive temozolomide PO QD on days 1-5. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
