Filter by:Despite surgery and first-line standard of care which consist of radiotherapy with concomitant and adjuvant temozolomide, all patients with glioblastoma (GB) will experience relapse. At the time of recurrence, therapeutic options include surgery or reirradiation in selected cases, while in other cases, bevacizumab, approved by Food and Drug Administration (FDA) but not European Medicines Agency (EMA), is the preferred option worldwide. Primary and acquired resistance to bevacizumab has been explored without definitive finding. Biomarkers able to predict response to antiangiogenic agents and particularly to bevacizumab are an unmet medical need. We have showed that a low Matrix metallopeptidase 9 (MMP9) or a high Matrix metallopeptidase 2 (MMP2) baseline plasma levels were associated with a high response rate and a prolonged Progression-free survival (PFS) and overall survival (OS) in recurrent GB patients treated with bevacizumab but not with cytotoxic chemotherapy. We also observed that MMP9 plasma level decreased during bevacizumab treatment and tend to increase at progression. Finally, in a retrospective analysis performed in the Avaglio trial (a randomized phase III trial that tested bevacizumab versus placebo in addition to standard of care in patients with newly diagnosed glioblastoma), a low plasma level of MMP9 at baseline predicted consistently PFS and OS gain associated to bevacizumab. These results are consistent with the role of MMP9 in vasculogenesis, since MMP9 contribute to the recruitment of circulating endothelial and myeloid precursors, an alternative vascularization process which is in part independent of the vascular endothelial growth factor (VEGF) pathway. Monoclonal Antibody (GS) 5745 is specifically directed against MMP9. First in human phase I study has been completed. Development is ongoing. Our results strongly support a role for MMP9 in the primary or acquired resistance to bevacizumab. Therefore, we hypothesize that the Monoclonal Antibody GS5745 may overcome resistance to bevacizumab through a specific inhibition of MMP9. While a preclinical program is initiated in our lab, the proposed phase I study is the first step to analyze the tolerance, determine the recommended dose of the combination and explore the impact of GS5745 on MMP9 plasma levels and multimodal imaging in patients with recurrent glioblastoma. Objective: Determine the safety profile and tolerability of GS5745 given in combination with a fixed dose of bevacizumab in patients with recurrent GB in terms of Dose-Limiting Toxicities. Multicenter, open label, dose-finding study of GS5745 in combination with bevacizumab administered at a fixed dose; both drugs will be administered once every two weeks for a total treatment duration of a maximum of 12 months. Before initiation of each new dose level, a meeting between the sponsor, the coordinator, the investigators and an independent external expert will take place to decide jointly the next dose.
Glioma is the most common primary cancer of the central nervous system, and around 50% of patients present with the most aggressive form of the disease, glioblastoma. Conventional therapies, including surgery, radiotherapy, and pharmacotherapy (typically chemotherapy with temozolomide), have not resulted in major improvements in the survival outcomes with only a median survival of around 15 months.The main reason may be related to the highly immunosuppressive tumor microenvironment. In recent years, the microbiome has emerged as a key regulator of not only systemic immune regulation but brain circuitry, neuro-physiology and microglia development. We hypothesized that there is a link between the gut microbiota and the GBM development and evolution through the immune regulation cells (microglia and tumor related macrophagocyte) in the blood circulation to impact the prognosis( PFS and MST) of GBM patients.
A Randomized, Double-Blind, Placebo-Controlled, Parallel, Multi-Center Study to Assess the Efficacy of BRCX014 Combined with Standard-Of-Care Treatment in Subjects with Glioblastoma Multiforme, Multiple Myeloma, and GI Malignancies
This clinical trial is to validate and demonstrate the clinical usefulness of a protocol for Magnetic Resonance Imaging (MRI) in people with high grade glioma brain tumors.
This study was conducted on the post-operative tumor tissues from 62 GBM patients. 20 slices are necessary for all the CD95 and CpG2 test in the central lab by the methods of immunisation and DNA methylation.
No predictive factors are known for the response to the bevacizumab anti-angiogenic molecule (Avastin) given in the event of relapse of glioblastoma (GBM) following radiochemotherapy. Classical MRI with gadolinium injection and perfusion is not sufficient to predict survival and response or duration. We propose to evaluate the prognostic interest for 6-month survival of spectroscopic biomarkers of proliferation, glial reaction, infiltration and glutaminergic metabolism or glycolytic metabolism recorded at 7 and 28 days of application of the treatment. These biomarkers are based on the increase of an index combining choline / Creatine (Cho / Cr), Glx / Cr (Glutamine and glutamate / Creatine), NAA / Cr (N acetyl aspartate / Creatine) and lactate / Cr ratios. The long-term objective is to predict the survival of these relapsed GBM patients at an early stage and to identify responder patients who would benefit from this expensive molecule and avoid using it in non-responding patients
Prospective, open-labeled, multicenter cohort trial for validation of the role of levetiracetam as a sensitizer of temozolomide in the treatment of newly diagnosed glioblastoma patients.
Testing the effect of providing an antidepressant and anxiety-type escitalopram for patients with glioblastoma on patient's quality of life including the effect of treatment on mood and cognition during treatment.Two subgroups will fill questionnaires : - Questionnaire mini mental state exam (mmse) which is the maximum score of 30. A score of below 24 indicates a flaw in the level of dementia - Questionnaire depression / mood PHQ9P(Pa t i e n t H e a l t h Qu e s t i o n n a i r e - 9) - The M. D. Anderson Symptom Inventory (MDASI) - Evaluation of the hospital situation awareness (clinical assessment and questionnaire) - Cognitive assessment which will be carried out by the Department neuropsychological and include: - Executive function (Stroop) - Abstract Reasoning (similarities) - -Auditory and Spatial Attention (Digit span, Spatial span) visual memory and remembering Literature - Memory function - visual and auditory (ROCF, RAVLT) - Language function: Naming and verbal fluency - Mindstreems Neurotrax
The tracer 11C-methionine (11 C-MET) is used as a specific cell proliferation tracer which shows metabolically active tumordeposities. A healthy brain barely takes up 11C-MET, causing the difference between the background and the tumor to be realively high. In addition, there is relatively little 11C-MET uptake in inflammatory processes. This makes 11C-MET a very suitable positron emission tomography (PET) tracer in order to differentiate between tumor progression and therapy changes. The latter is a major clinical problem for which further investigation is necessary. In order to be able to make this differentiation, a direct post-operative baseline scan is required. With regard to the advanced MRI sequences, it is known that it is necessary to produce the post-operative baseline scan within 48 hours. After that timeframe, operation induced changes start to occur, such as granulation tissue. In that case the interpretation of the scan is no longer possible. Immediately postoperatively (<48 hours) 11C-MET has never been used before. Therefore, it is unknown whether 11C-MET provides a good baseline scan directly after surgery. This pilot will investigate the feasibility of this 11C-MET baseline scan and comparison the results with the advanced MRI sequences.
The purpose of this study is to determine whether Q cells separated from the glioma sample are determinants in treatment response and prognosis of glioma patients
