Brief Title † A Explore Study of Bevacizumab Combined With Conventional Therapy in Glioblastoma
Official Title † An Open-label, Single Arm Study to Explore Whether Potential Image Biomarkers Correlate With Efficacy of Bevacizumab Combined With Conventional Therapy in Newly Diagnosed Glioblastoma
Brief Summary This is a single-center, open-label, single arm study to explore whether potential image biomarkers correlate with efficacy of bevacizumab combined with conventional therapy in newly diagnosed glioblastoma. Despite the increase in therapies available, the median survival of patients with glioblastoma multiforme (GBM) remains less than 15 months. The phase III pivotal study in newly diagnosed GBM also met its co-primary endpoint of progression-free survival (PFS) which further confirm the efficacy of bevacizumab in GBM. Early predicting the efficacy of bevacizumab combined with conventional therapy in newly diagnosed glioblastoma could help us to identify the suitable patients to receive suitable treatment in GBM. Thus, characterizing the blood flow and blood volume in the tumor and their changes during therapy might provide information on vasculature growth or collapse,edema formation, tumor growth, and/or cell death(necrosis) .We decided to investigate whether the estimation of blood circulation in tumor, using MRI,PET could be used as a surrogate marker to predict the early response of GBM to bevacizumab. Several previous studies have demonstrated that the relative cerebral blood volume (rCBV) correlated with the histologic grade of gliomas and investigated the prognostic value of the tumor CBV for survival.In current study, We hypothesized that, the temporal changes during anti-angiogenesis therapy in specific regions of high and low perfusion in glioblastoma might predict the efficacy of bevacizumab.Since there is no mature PET tracer directly image Vascular Endothelial Growth Factor (VEGF) in China,we use 18F-Galacto-arginine-glycine-aspartic acid (RGD)—— a new tracer for PET imaging of αvβ3 by testing Standardized uptake value mean (SUVmean),Standardized uptake value max (SUVmax) and tumor to non-tumor tissue ratios (T/NT) to indirectly reflect the VEGF expression. The integrin αvβ3 is an important receptor affecting tumor growth, local invasiveness, and metastatic potential. Specifically, αvβ3 is highly expressed on activated endothelial cells during angiogenesis. Therefore, in the pilot study, we use dynamic contrast enhanced magnetic resonance imaging (DCE-MRI),dynamic susceptibility-contrast magnetic resonance imaging (DSC-MRI) and 18F-Galacto-RGD PET to explore the potential image biomarkers of bevacizumab used in newly diagnosed glioblastoma.
Detailed Description 20 patients with newly diagnosed histopathologically confirmed glioblastoma (WHO Grade IV) after surgery will be enrolled in the study. All of the patients will receive conventional concurrent chemoradiation and adjuvant temozolomide plus bevacizumab begin > 3 weeks and ≤ 5 weeks after surgery.

Study Arms / Comparison Groups Chemoradiation & Adjuvant Therapy: Concurrent chemoradiation Therapy: Radiation therapy:2 Gy will be given daily 5 days per week for a total of 60 Gy over 6 weeks. Temozolomide from day 1 of radiotherapy to the last day of radiation at a daily oral dose of 75 mg/m2 for a maximum of 49 days. Bevacizumab will be administered intravenously on days 1 and 15 of each 28-day cycle,at the beginning of the 4th week of radiation. The dose will be 10 mg/kg. Adjuvant Therapy: Temozolomide once per day for 5 consecutive days of a cycle. The starting dose for the first cycle will be 150 mg/m2/day, with a single dose 200 mg/m2/day in subsequent cycles if no treatment-related adverse events> grade 2 are noted. Bevacizumab will be administered intravenously on days 1 and 15 of each 28-day cycle. The dose will be 10 mg/kg.
