Exclusion Criteria:

• - Recurrent malignant gliomas.

• - Metastases detected below the tentorium or beyond the cranial vault.

• - Prior chemotherapy or radiation therapy (RT) for the diagnosis of GBM or for cancers of the head and neck.

• - Pregnant or lactating women.

• - History of allergic reactions or intolerance to any of the required agents on the study.

• - History of hypersensitivity to dacarbazine.

- Other condition(s) that in the opinion of the investigator might compromise the objectives of the study or increase patient risk

PRIMARY OBJECTIVES:

• I. To determine the recommended phase 2 dose (RP2D) of dimethyl fumarate (DMF) when combined with standard concurrent temozolomide and RT in subjects with newly diagnosed glioblastoma multiforme (GBM).

SECONDARY OBJECTIVES:

• I. To evaluate the safety, tolerance, and toxicity of DMF when combined with standard concurrent temozolomide and RT in subjects with newly diagnosed GBM.

• II. To obtain a preliminary estimate of the efficacy of DMF when combined with standard concurrent temozolomide and RT in subjects with newly diagnosed GBM.

OUTLINE: This is a dose-escalation study of dimethyl fumarate. CONCOMITANT THERAPY: Between 21 days (3 weeks) and 42 days (6 weeks) following the last surgical procedure, patients receive temozolomide orally (PO) once daily (QD) for 42-49 days and dimethyl fumarate PO twice daily (BID) or thrice daily (TID) continuously. Patients also undergo radiation therapy 5 days a week over 6 weeks for a total of 30 fractions. MAINTENANCE THERAPY: Patients continue to receive dimethyl fumarate PO BID or TID continuously. Four weeks after completing concomitant temozolomide and radiation therapy, patients also receive temozolomide PO QD on days 1-5. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 30 days and then every 2 months thereafter.
