• - Arm 2 patients must have progressed/recurred on bevacizumab as the most recent regimen; patients on arm 2 should continue on bevacizumab as clinically necessary to control brain edema.

• - Patients must have a tumor tissue form indicating availability of archived tissue from initial resection at diagnosis of glioblastoma completed and signed by a pathologist; availability of tissue is not a requirement for study participation.

• - Patients must have recovered from severe toxicity of prior therapy; the following intervals from previous treatments are required to be eligible: - 12 weeks from the completion of radiation.

• - 6 weeks from a nitrosourea chemotherapy.

• - 3 weeks from a non-nitrosourea chemotherapy.

• - 2 weeks from administration of a non-cytotoxic, FDA-approved agent (e.g., erlotinib, hydroxychloroquine, etc.) - Patients must have a Karnofsky performance status >= 60% (i.e. the patient must be able to care for himself/herself with occasional help from others) - Absolute neutrophil count >= 1,500/mcL.

• - Platelets >= 100,000/mcL.

• - Hemoglobin >= 9 g/dL.

• - Total bilirubin =< institutional upper limit of normal.

• - Creatinine =< institutional upper limit of normal OR creatinine clearance >= 60 ml/min/1.73 m^2 for patients with creatinine levels above institutional normal.

• - Activated partial thromboplastin time (APTT) or partial thromboplastin time (PTT) =< 1.5 x institutional upper limit of normal.

• - Patients must be able to provide written informed consent.

• - Women of childbearing potential must have a negative serum pregnancy test prior to study start; women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and through 30 days after the last dose of study drug; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and through 30 days after the last dose of study drug.

• - Patients must have no concurrent malignancy except curatively treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix, breast, or bladder; patients with prior malignancies must be disease-free for >= five years.

• - Patients must be able to swallow capsules.

Exclusion Criteria:

• - Patients receiving any other investigational agents are ineligible.

• - Patient must not have known sensitivity to TRC102 or any formulation excipients.

• - Patients on enzyme-inducing anti-epileptic drugs (EIAED) are not eligible for treatment on this protocol; patients may be on non-enzyme inducing anti-epileptic drugs or not be taking any anti-epileptic drugs; patients previously treated with EIAED may be enrolled if they have been off the EIAED for 10 days or more prior to the first dose of TRC102.

• - Patients must not be on any anticoagulation.

• - Patient must not have prior gastrointestinal (GI) surgery or GI disease that might interfere with the absorption of TRC102.

• - Patients who have not recovered to < Common Terminology Criteria for Adverse Events (CTCAE) grade 2 toxicities related to prior therapy are ineligible.

• - Patients must not have active brain metastases from a systemic solid tumor.

• - Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, clinically significant cardiac disease, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements, are ineligible.

• - Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with TRC102.

- Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible

PRIMARY OBJECTIVES:

• I. To estimate the efficacy of TRC102 (methoxyamine) and temozolomide, as measured by response rate, in bevacizumab naïve glioblastoma.

(Arm I)

• II. To estimate the efficacy of TRC102 and temozolomide, as measured by response rate, in bevacizumab refractory glioblastoma.

(Arm II) SECONDARY OBJECTIVES:

• I. Evaluate the toxicities of oral TRC102 and temozolomide in this patient population.

• II. Estimate the efficacy of TRC102 and temozolomide, as measured by progression-free survival, progression-free survival at 6 months and overall survival, in bevacizumab naïve glioblastoma.

• III. Estimate the efficacy of TRC102 and temozolomide, as measured by progression-free survival in bevacizumab refractory glioblastoma.

TERTIARY OBJECTIVES:

• I. Assess the tissue correlates of N-methylpurine-deoxyribonucleic acid (DNA) glycosylase (MPG), topoisomerase II-alpha (topo II a), and O-6-methylguanine-DNA methyltransferase (MGMT) status, with response, progression-free survival (PFS), and overall survival.

OUTLINE: Patients receive methoxyamine orally (PO) once daily (QD) and temozolomide PO QD on days 1-5. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 30 days, every 2 months for 2 years, and then every 6 months thereafter.
