Cytochrome C Oxidase Activity in Newly Diagnosed Glioblastoma Multiforme (GBM)

Inclusion Criteria

1. Willingness and ability to provide written informed consent and to comply with the study protocol as judged by Physician interview (NOTE: This could be patient's Neurosurgeon, Neuro-Oncologist or Study Investigator). If patient lacks capacity to consent, a legally authorized representative is allowed to provide written informed consent.
2. Age ≥ 21 years
3. Karnofsky Performance Status (KPS) ≥ 60.
4. Subjects' planned upfront treatment to be standard of care treatment with radiotherapy and temozolomide (i.e. TEMODAR) for histologically confirmed GBM at initial diagnosis
5. No history of other malignancies except adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, or other curatively treated solid tumors with no evidence of disease for at least 5 years.
6. No serious active infection (e.g., wound infection requiring parenteral antibiotics) or other serious underlying medical conditions that in the opinion of the investigator would compromise standard of care treatment.
7. No other condition (e.g., psychological or geographical) that would preclude study compliance.
8. An MRI that is consistent with a primary malignant glioma
9. Histologically confirmed newly diagnosed primary GBM before treatment using World Health Organization (WHO) classification criteria (A local pathology report constitutes adequate documentation of histology for initial study enrollment, however central pathology review will be required to confirm the diagnosis of GBM for final data analysis).
10. Viability of tumor tissue representative of GBM ≥ 70 mg, snap-frozen within 30 minutes of resection, 10 minutes or less at room temperature.
11. All subjects must have received maximal safe resection followed by standard radiation therapy with concomitant Temozolomide taken during the course of radiation therapy.

Exclusion Criteria:

Exclusion criteria are proposed that will exclude subjects with pre-existing co-morbidities that could contribute to pre-mature death (e.g., significant cardiovascular history), with non-included pretreated tumors occupying either intracranial and extra-axial space, significantly impaired neurological performance status (e.g., KPS\>60), with glial tumors that are genomically distinct from primary GBM tumors (e.g., gliomas arising from a previously diagnosed lower grade than GBM) or those unable to complete the fundamental requirements of the study.

1. Inability to fulfill the requirements of the protocol
2. Secondary GBM or other gliomas.
3. History of sensitivity to Temozolomide.
4. Planned upfront treatment with any anti-angiogenic agent targeting the (vascular endothelial growth factor (VEGF) pathway including but not limited to bevacizumab, cediranib, vandetanib, sunitinib, pazopanib, aflibercept, or sorafenib or any immunotherapy regimen.
5. Any severe post-operative infection or other complications that may significantly delay the initiation of brain tumor therapy, or other conditions that, in the opinion of the investigator, would compromise the subject's ability to participate in the study.

Note: Use of Gliadel wafers, in combination with surgical resection, is allowed if the patient is to follow standard-of-care treatment post-operatively (i.e., radiation therapy with temozolomide). Use of Gliadel wafers during surgery with only radiation therapy post-operatively is excluded (i.e., omitting temozolomide).
