Eligibility Criteria

        Inclusion Criteria:

          -  Histopathologically proven newly diagnosed glioblastoma (GBM, WHO Grade IV) or

             maximum diameter is greater than 5 cm, the subject is still eligible if the PTV is
             less than 113 cm3 which is the volume of a 6 cm diameter sphere.

               -  Hemoglobin (Hgb) ≥ 9 g/dL (90 g/L); < 9 g/dL (< 90 g/L) is acceptable if
                  hemoglobin is corrected to ≥ 9 g/dL (90 g/L) as by growth factor or transfusion
                  prior to Day 0

               -  Platelet count ≥ 100 × 109/L without blood transfusions for 7 days preceding the
                  lab assessment

               -  Bilirubin ≤ 1.5 × upper limit of normal (ULN), except for subjects with
                  documented history of Gilbert's disease

               -  Alanine aminotransferase (ALT), and aspartate aminotransferase (AST) ≤ 2.5 × ULN

               -  Alkaline phosphatase (AP) ≤ 3 × ULN

               -  Women of childbearing potential (WCBP): negative serum pregnancy test (this test
                  is required of all women unless post menopausal, defined as 12 consecutive months
                  since last regular menses or surgically sterile)

          -  Ability to tolerate MRI

          -  Karnofsky Performance Scale (KPS) ≥ 60

          -  Ability to understand and the willingness to sign (personally or by a legal authorized
             representative) the written IRB approved informed consent document.

        Exclusion Criteria:

          -  Previous chemotherapy or radiotherapy for glioma

          -  Concurrent use of experimental therapies

          -  Known allergy to adhesive tapes or other skin adhesives used in medical care

          -  Known underlying skin hypersensitivity or other condition of the scalp with potential
             toxicity per pre treatment dermatology evaluation

          -  Subjects with the following co morbid disease or incurrent illness:

               -  Subjects with known cirrhosis diagnosed with Child Pugh Class A or higher liver
                  disease.

               -  Prior malignancy except for non melanoma skin cancer and carcinoma in situ (of
                  the cervix or bladder), unless diagnosed and definitively treated more than 3
                  years prior to first dose of investigational drug

               -  Severe/uncontrolled inter current illness within the previous 28 days prior to
                  first day of treatment

               -  Subjects who have implantable devices that are contra indicated for use with
                  TTFields

               -  Any other significant co morbid conditions that in the opinion of the
                  investigator would impair study participation or cooperation.

          -  Subjects receiving the following medications at the time of combined TTFields and SRS:

               -  Pharmacotherapy for tuberculosis or HIV as these medications are known to
                  interact with temozolomide

               -  Other chemotherapy, other investigational agents, or biologic agents for the
                  treatment of cancer including antibodies (eg, bevacizumab, trastuzumab,

Primary Outcome Measures

Measure:Dose-limiting Toxicity (DLTs)
Time Frame:5 months
Safety Issue:
Description:Dose limiting toxicities (DLTs) are defined as possibly, probably, or definitely related adverse events that are severe or medically significant, and needing topical & systemic therapy; needing surgery intervention; needing hospitalization; needing treatment interruption; or life threatening. Late DLTs will be assessed as the number of DLTs that occur in the period from 31 days after the start of treatment through 5 months after the start of treatment. The outcome will be reported as a number without dispersion.

Secondary Outcome Measures

Measure:Acute dose limiting toxicity
Time Frame:1 month
Safety Issue:
Description:Dose limiting toxicities (DLTs) are defined as possibly, probably, or definitely related adverse events that are severe or medically significant, and needing topical & systemic therapy; needing surgery intervention; needing hospitalization; needing treatment interruption; or life threatening. Acute DLTs will be assessed as the number of DLTs that occur in the period from the start of treatment through 30 days after the start of treatment. The outcome will be reported as a number without dispersion.
Measure:Progression-free Survival (PFS) at 6 Months
Time Frame:6 months
Safety Issue:
Description:Progression-free survival is defined as the number of evaluable participants who, at 6 months from the date of surgical resection or biopsy (PFS6), are alive without disease progression, death, or other defined event (study withdrawal or loss to follow up). Disease progression is defined as ≥ 25% increase in product of perpendicular diameters of the lesion; any increase in MRI T2/FLAIR lesion area from previous MRI scan; MRI detection of a new lesion; decline in clinical status not attributable to causes other than the tumor. The outcome will be reported as the number without dispersion.
Measure:Overall Survival (OS)
Time Frame:30 months
Safety Issue:
Description:Overall survival (OS) will be assessed as the number of evaluable participants who remain alive from the date of surgical resection or biopsy. The outcome will be reported as the number without dispersion.
