This Biomarker trial is designed to prospectively evaluate the hypothesis that the overall survival (OS) time of a subject with newly diagnosed primary GBM tumors, treated by standard of care (SOC), is a function of the CcO enzymatic activity in the tumor (OS; time interval from date of first diagnosis to death from any cause, irrespective of post-SOC therapies, assessed up to 24 months from accrual). In particular, tumors with high CcO activity are associated with shorter OS time as compared to tumors with low CcO activity. SOC consists of post-surgical radiation therapy with concurrent Temozolomide followed by up to 12 cycles of adjuvant Temozolomide.
Additional outcomes are to study the relation between CcO activity in the GBM tumors and progression free survival times (PFS; time intervals from dates of diagnosis to documented disease progression by MRI or tumor-related death) and, to compare the prognostic abilities of CcO activity to other frequently used biomarkers, namely the methylation status of O6-methylguanine-DNA methyltransferase (MGMT), on OS and PFS.
Tumor tissue will be submitted by participating centers for measurements of the CcO/Citrate Synthase (CS), MGMT promoter methylation. The subjects will agree to receive the SOC treatment. The therapeutic option at the time of first recurrence is at the discretion of the treating physician. PFS and OS times will be compared with high vs. low CcO activity and with the MGMT methylation status of the tumor. At the time of death or at 24 months s/p enrollment (whichever comes first), the site PI will complete an exit form documenting the details of enrollees' treatment history and date(s) of any tumor progression.

- Overall Survival (OS) [ Time Frame: Date of diagnosis through 24 months after enrollment ]This biomarker trial is designed to prospectively evaluate the hypothesis that the overall survival (OS) time of a subject with newly diagnosed primary GBM tumors, treated by standard of care (SOC), is a function of the CcO enzymatic activity in the tumor. OS is defined as the time interval from date of first diagnosis to death from any cause, irrespective of post-SOC therapies, assessed up to 24 months from accrual.
- Progression Free Survival (PFS) [ Time Frame: Date of diagnosis through 48 months after enrollment ]This biomarker trial is designed to prospectively evaluate the hypothesis that progression free survival time (PFS) is a function of the CcO enzymatic activity in the tumor. PFS is defined as time interval from date of surgery to first documented progression according to the RANO criteria, irrespective of post-SOC therapies.
- MGMT methylation status on OS and PFS [ Time Frame: Date of diagnosis through 24 months after enrollment ]Compare the prognostic abilities of CcO activity to another frequently used biomarker, the methylation status of O6-methylguanine-DNA methyltransferase (MGMT) on OS and PFS times.

| Sampling Method: | Non-Probability Sample |
Inclusion Criteria
- 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.
- Age ≥ 21 years
- Karnofsky Performance Status (KPS) ≥ 60.
- Subjects' planned upfront treatment to be standard of care treatment with radiotherapy and temozolomide (i.e. TEMODAR) for histologically confirmed GBM at initial diagnosis
- 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.
- 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.
- No other condition (e.g., psychological or geographical) that would preclude study compliance.
- An MRI that is consistent with a primary malignant glioma
- 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).
- Viability of tumor tissue representative of GBM ≥ 70 mg, snap-frozen within 30 minutes of resection, 10 minutes or less at room temperature.
- 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.
- Inability to fulfill the requirements of the protocol
- Secondary GBM or other gliomas.
- History of sensitivity to Temozolomide.
- 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.
- 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).

| Plan Description: | The requestor must submit a formal written request for data sharing, and the request must be approved by the NeuroNEXT Steering Committee and the Publication Committee before any data are shared. Prior to data sharing, the DCC and the external source must also execute a data sharing agreement that includes a description of the data that are requested and how the data will be shared. A contract / usage agreement may be required. The DCC will submit de-identified datasets and associated documentation to NINDS for archiving and public access, consistent with the current NINDS Data Sharing policy. The DCC will provide documentation with each final dataset to ensure that other users can efficiently and accurately use the dataset, and to prevent misinterpretation or misuse. This documentation may include information about how the data were collected, provide details about the code used to generate the dataset, and define variables and variable field locations. |
