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.
This phase II clinical trial studies how well ERC1671 plus Granulocyte-macrophage colony-stimulating factor (GM-CSF) plus Cyclophosphamide with Bevacizumab works compared to Placebo Injection plus Placebo Pill with Bevacizumab in treating patients with recurrent/progressive, bevacizumab naïve glioblastoma multiforme and gliosarcoma (World Health Organization (WHO) grade IV malignant gliomas, GBM).
This phase I trial studies the side effects and best dose of adavosertib when given together with radiation therapy and temozolomide in treating patients with glioblastoma that is newly diagnosed or has come back. Adavosertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. 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. Giving adavosertib, radiation therapy, and temozolomide may work better in treating patients with newly diagnosed or recurrent glioblastoma compared to radiation therapy and temozolomide alone.
The purpose of this research study is to test the safety, tolerability, and effectiveness of the combination of three drugs, sorafenib (Nexavar®), valproic acid (Depakote®), and sildenafil (Viagra®), when used to treat high-grade glioma, a type of brain tumor.
Glioblastoma is the most frequent primary malignant brain tumor in adults (3,000 new cases per year) and is characterized by a poor prognosis (median survival 12 months). Treatment is based mainly on surgical excision as complete as possible followed by an additional radiochemotherapy. The prognosis depends mainly on the quality of resection when it is macroscopically complete. Different techniques to support the surgical resection have been developed over the past 20 years. The reference technique is currently the intraoperative neuronavigation for guiding excision by matching the intraoperative tumor boundaries with those of the preoperative MRI. Its main drawback is the loss of precision during the resection related to changes in anatomical limits of the tumor. The per-operative fluorescence-guided surgery (FGS) is an innovative alternative technique to support the surgical resection. The 5-aminolevulinic acid (5-ALA), a molecule absorbed by the patient before surgery is captured specifically by the tumor cells and transformed into a fluorochrome revealed intraoperatively by a light source length adapted wave with a set of lenses included in the microscope. Resection is thus guided by this fluorescence whose disappearance translates complete tumor resection. Its interest is twofold: - Increase the percentage of complete tumor resection. - Improve disease-free survival and overall survival. The objective of the study is to compare the FGS to the intraoperative neuronavigation for the resection of glioblastoma, on a medical and economical level through a randomized, prospective, multicenter trial. The annual number of patients likely to benefit of this technique in France is estimated at 2200 new cases.
This is a phase 1 (first in man) study testing the safety of adding high dose ascorbate (vitamin C) to standard radiation and chemotherapy for initial treatment of glioblastoma multiforme (GBM).
The purpose of the study is to see whether treatment with LY2157299 on its own, LY2157299 plus lomustine therapy or lomustine plus placebo can help participants with brain cancer
This study will look at the effects, good and/or bad, of treating primary brain cancers with diet therapy using an energy restricted ketogenic diet (ERKD) that uses food. An energy restricted ketogenic diet is a diet designed to keep blood sugars in the low range of normal while at the same time increasing the blood concentration of metabolic break down products called ketones. This diet is currently used to treat children with uncontrollable seizures. This diet is well tolerated by the children with minimal side effects reported after using the diet for years. - The main purpose of this study is to find out whether or not the energy restricted ketogenic diet will help patients with primary brain cancer by either decreasing the size of the cancer or by keeping the cancer from growing. - Another reason for doing this study is to learn about the side effects associated with the energy restricted ketogenic diet in patients with primary brain cancer.
This open-label study will evaluate the safety and efficacy of TSC when dosed concomitantly with the standard of care (radiation therapy and temozolomide) for newly diagnosed glioblastoma in adults. All patients will receive TSC in the study. The objective of the study is to evaluate the effect of TSC on survival and tumor response in patients with GBM while establishing an acceptable patient risk profile.
