Methoxyamine and Temozolomide in Treating Patients With Recurrent Glioblastoma

Phase 2

Terminated

Conditions: Adult Brain Glioblastoma

Interventions: Other: Treatment
Drug: Methoxyamine
Drug: Temozolomide

Registration Number: NCT02395692

Lead Sponsor: National Cancer Institute (NCI)

Brief Summary: This phase II trial studies how well methoxyamine works when added to standard temozolomide in treating patients with glioblastoma that has come back. Drugs used in chemotherapy, such as methoxyamine and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

Detailed Description: 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.

Platelets >= 100,000/mcL
Hemoglobin >= 9 g/dL

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
