Dimethyl Fumarate, Temozolomide, and Radiation Therapy in Treating Patients With Newly Diagnosed Glioblastoma Multiforme

Phase 1

Completed

• Conditions: Adult Brain Glioblastoma; Adult Giant Cell Glioblastoma; Adult Gliosarcoma
• Interventions: Drug: Dimethyl Fumarate; Drug: Temozolomide; Radiation: Radiation Therapy

• Registration Number: NCT02337426
• Lead Sponsor: Virginia Commonwealth University

Brief Summary

This phase 1 trial studies the side effects and best dose of dimethyl fumarate when given together with temozolomide and radiation therapy(RT) in treating patients with newly diagnosed glioblastoma multiforme (GBM). Dimethyl fumarate may help radiation therapy work better by making tumor cells more sensitive to the radiation therapy. Drugs used in chemotherapy, such as 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. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving dimethyl fumarate with temozolomide and radiation therapy may work better in treating glioblastoma multiforme.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
RP2D for DMF when combined with concurrent temozolomide and radiotherapy determined by the incidence of dose limiting toxicities (DLTs) graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0	Up to 6 weeks	Subjects' treatment dosing level, dose modification, DLTs, and evaluability for DLTs and response will be listed and summarized by basic descriptive statistics (such as frequency and proportion).

Secondary Outcome Measures

Name	Time	Method
Progression free survival (PFS)	Time from registration to time of symptomatic and/or radiographic progression or death, whichever occurs first, assessed up to 2 years	The Kaplan-Meier method will be conducted to describe PFS, and median PFS will be estimated, along with 95% confidence intervals. A Cox regression model may be used to model the PFS and adjusting for any effects of potential clinical characteristics.
Overall survival (OS)	Time from registration until death from any cause, assessed up to 2 years	The Kaplan-Meier method will be conducted to describe OS, and median OS will be estimated, along with 95% confidence intervals. A Cox regression model may be used to model the OS and adjusting for any effects of potential clinical characteristics.
Incidence of adverse events graded according to NCI CTCAE version 4.0	Up to 30 days after completion of treatment	Subjects' demographics, adverse events, serious adverse events, and treatment status will be listed and summarized by descriptive statistics (such as frequency, proportion, mean, standard deviation, median, and range).
Response rate assessed as per the Response Assessment in Neuro-oncology for magnetic resonance imaging scans or Macdonald criteria for computed tomography scans	Up to 2 years	The clinical response rate will be calculated for each cohort, along with their corresponding 95% confidence intervals. Logistic regression may be used to model the rate by adjusting potential clinical characteristics (such as age, gender, and tumor grade). Mean and standard deviation of duration of response (overall response, complete response, and stable disease, respectively), along with its 95% confidence interval, will be estimated based on the method proposed by Ellis et al. via the exponential distribution.
