Exploratory Study of the Modulation of the Immune System by VEGF Blockade in Patients With Glioblastoma Multiforme (GBM)

This study is ongoing, but not recruiting participants.

Blood samples will be obtained from newly diagnosed GBM patients treated with combined radiotherapy (RT), temozolomide (TMZ) and bevacizumab (BEV) at specific time points. The primary outcome is the shift in T reg cell fraction a defined by determining the proportion of CD4 cells that are CD4+ CD25.

Condition Intervention Phase
Glioblastoma Multiforme
Drug: Bevacizumab
Early Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Basic Science
Official Title: DMS 0947 Exploratory Study of the Modulation of the Immune System by Vascular Endothelial Growth Factor (VEGF) Blockade in Patients With Glioblastoma Multiforme (GBM)

Primary Outcome Measures:
  • Changes in the peripheral blood T-reg profile between pretreatment and 4 weeks after completion of treatment with the addition of bevacizumab to RT and TMZ in patients with glioblastoma [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • Immunologic shift in the phenotypic T cell, B cell, NK cell and DC repertoire induced by RT-TMZ-BEV comparing pretreatment and 4 weeks after completion of treatment [ Time Frame: 1 year ]

Estimated Enrollment: 11
Study Start Date: March 2010
Estimated Study Completion Date: July 2017
Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Bevacizumab
Bevacizumab + temozolomide + radiotherapy followed by adjuvant bevacizumab + temozolomide
Drug: Bevacizumab
Bevacizumab every 2 weeks 10mg/kg beginning 2 weeks after start of Radiation Therapy
Other Name: Avastin

Detailed Description:
Glioblastoma multiforme (GBM) is the most frequent malignant brain tumor and it remains a lethal disease. Approximately 4 weeks post surgery for tumor resection, patients will proceed to standard of care treatment which currently consists of temozolomide (TMZ) with concurrent radiation therapy (RT) for 6 weeks. This study will add bevacizumab (BEV) to the standard of care regimen in newly diagnosed patients. The Bevacizumab will be added 2 weeks post start of RT/TMZ. Administration of bevacizumab will continue concurrently with TMZ every 2 weeks for 12 months. Blood samples will be obtained from these patients at 3 different time points during this study.
