- Dose-limiting toxicity, defined as the absence of cardiac arrhythmia measured by electrocardiogram (ECG) or grade III or IV adverse events, using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [ Time Frame: Up to 30 days post plerixafor ]Adverse events and qualifying dose limiting toxicity (DLT) will be tabulated by cohort, site and severity.
- Progression free survival based on the Response Assessment for Neuro-Oncology (RANO) criteria, using both clinical examinations and MRIs with and without contrast [ Time Frame: At 6 months ]Summarized with Kaplan Meier estimates.

Experimental: Treatment (radiation therapy, temozolomide, plerixafor)
Within 4 weeks of surgery, patients undergo radiation therapy and receive temozolomide PO over 42 days. Beginning 8 days prior to completion of chemoradiotherapy, patients receive plerixafor IV continuously for 2-4 weeks. Patients also receive temozolomide PO 5 days a month beginning 35 days after completion of radiation therapy.

I. To assess the safety of using continuous infusion Plerixafor subsequent to irradiation in patients with newly diagnosed glioblastoma multiforme (GBM).
II. To assess the efficacy of Plerixafor as measured by progression free survival at 6 months (PFS6) from the start of irradiation.
OUTLINE: This is a phase I, dose-escalation study of plerixafor followed by a phase II study.
Within 4 weeks of surgery, patients undergo radiation therapy and receive temozolomide orally (PO) over 42 days. Beginning 8 days prior to completion of chemoradiotherapy, patients receive plerixafor intravenously (IV) continuously for 2-4 weeks. Patients also receive temozolomide PO 5 days a month beginning 35 days after completion of radiation therapy.
After completion of study treatment, patients are followed up every 12 weeks for 5 years.
