Plerixafor After Radiation Therapy and Temozolomide in Treating Patients With Newly Diagnosed High Grade Glioma
This pilot phase I/II trial studies the side effects and best dose of plerixafor after radiation therapy and temozolomide and to see how well it works in treating patients with newly diagnosed high grade glioma. Plerixafor may stop the growth of tumor cells by blocking blood flow to the tumor. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high energy x rays to kill tumor cells. Giving plerixafor after radiation therapy and temozolomide may be an effective treatment for high grade glioma.

- 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 ] [ Designated as safety issue: Yes ]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 ] [ Designated as safety issue: No ]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.
