Active clinical trials for "Glioma"

This phase I trial investigates the efficacy and safety of brain-targeting epidermal growth factor receptor chimeric antigen receptor immune cells (EGFRvIII-CAR T cells) in treating patients with leptomeningeal disease from glioblastoma. T cells are part of the immune system and help the body fight malignant tumours. Immune cells can be genetically modified to destroy brain tumor cells in the laboratory. EGFRvIII -CAR T cells are brain tumor specific and can enter and express its genes in immune cells. Administering patients EGFRvIII -CAR T cells may help to recognize and destroy brain tumor cells in patients with leptomeningeal disease from glioblastoma.

The main goal of high grade glioma (HGG) surgery is to achieve gross total resection (GTR) without causing new neurological deficits1-8. Intraoperative navigated high resolution ultrasound (US) is a promising new tool to acquire real-time intraoperative images to localize and to resect gliomas9-12. The aim of this study was to investigate whether intraoperative guided surgery leads to a higher rate of GTR, when compared with standard non-ultrasound guided surgery.

Simultaneous integrated boost (SIB), a field-in-field escalation technique, has been introduced to deliver higher radiation dose to the certain part of target with the same fractionation scheme. The aim of this study was to investigate the value of chemoradiation (CCRT) using SIB in glioblastoma and the correlation with surgical extent.

This trial is aimed at evaluating the safety and efficacy of IDH1R132H-DC vaccine in glioma with IDH1R132H mutation.

Purpose of the study is to answer the question whether confocal laser endomicroscopy (CLE, also named 'optical biopsy') might improve the results of medically necessary neurosurgery to prove practicability, safety and harmlessness of CLE during neurosurgical procedures

A pilot study to determine the safety and efficacy of chimeric antigen receptor T cell (autologous T cells transduced with a lentiviral vector expressing chimeric antigen receptor with or without anti-PDL1 antibody) personalized immunotherapy for patients with recurrent malignant gliomas based on the expression of tumor specific/associated antigens (EGFRVIII, IL13Rα2, Her-2, EphA2, CD133, GD2).

Diffuse Intrinsic Pontine Gliomas (DIPG) appear almost exclusively in children and adolescents, representing 15 to 20% of posterior fossa tumours. Even if it is one of the most common malignant brain tumours, there are only 30 to 40 new cases per year in France. Their clinical presentation is stereotyped with a short clinical history and a unique MRI appearance that was usually considered as sufficient to establish the diagnosis. The prognosis of DIPG is always unfavourable; median overall survival is 9 to 10 months in general and most patients will die within two years after diagnosis (Kaplan 1996,Hargrave 2006). Malignant gliomas infiltrating the brainstem represent the greatest challenge of paediatric oncology; despite numerous collaborative studies performed, patients' survival has not significantly increased in thirty years (Hargrave 2009). There is no validated prognostic factor. There is currently no validated treatment except radiotherapy. Several targeted agents have been tested in DIPG (Pollack 2007 Haas-Kogan 2008, Geoerger, 2011), without knowing whether the target was present in the tumour. A critical review of the paradigms of these trials tells us that there are long term survivors in these studies that is to say patients who may have benefited from the tested therapy, but they are few. So far, the new therapies that have been tried were evaluated one after the other in search of a treatment that would be effective for all patients, measuring the treatment effect on median survival. They were all rejected as ineffective. However the investigators can challenge the endpoint to evaluate efficacy in these trials as the existence of long term survivors (> 18 months, for example) and their number should not been ignored, especially if targeted therapies are considered. The investigators propose a paradigm shift in the choice of treatment; the issue raised would be to give to each patient the treatment associated with the highest likelihood of efficacy based on the specific biological tumour profile. The development of targeted therapies for malignant gliomas infiltrating the brainstem has been hampered by the absence of biological data. It is therefore crucial to better understand the biology of these tumours. Despite the safety of the biopsy in brainstem tumours, most teams of paediatric neurosurgery limit the use of stereotactic biopsy only for clinically or radiologically unusual forms. Until recently, there has been no systematic genetic study at diagnosis to date and the few available data were confounded by the inclusion of autopsies or clinically and radiologically unusual cases (Louis, 1993; Gilbertson 2003; Okada, 2008; Zarghooni 2010; Broniscer, 2010; Wu, 2012 and Schwartzentruber, 2012). French teams gathered in the French Society of Paediatric Oncology and the European consortium "Innovative Therapies in Children with Cancer (ITCC)" decided a few years ago to perform biopsies of these tumours for diagnostic confirmation and to ensure the presence of certain therapeutic targets prior to a possible inclusion in a trial evaluating a targeted therapy (Geoerger, 2009; Geoerger, 2010). Part of this experiment was reported by the team of the Necker Hospital in Paris, confirming the low rate of complications of stereotactic biopsy procedure (Roujeau, 2007). The biopsy specimen analysis allowed practicing immunohistochemical, genomic (CGHarray), gene expression (transcriptome) and direct sequencing of candidate genes studies. In this study, the majority of patients will receive a treatment assumed to specifically target a biological abnormality identified on the biopsy. More importantly, patients will not receive a drug for which the identified target is absent. In this first step of the protocol, the patients will thus be allocated to one of the three treatment groups as follows: If the tumor overexpresses EGFR without PTEN loss of expression, patients may receive erlotinib or dasatinib allocated by randomization (R1 randomisation). If the tumor shows loss of PTEN expression without EGFR overexpression, patients may receive everolimus or dasatinib allocated by randomisation (R2 randomisation). If the tumor shows both EGFR overexpression and loss of PTEN expression, patients may receive erlotinib, everolimus or dasatinib by randomisation (R3 randomisation). If the tumor shows neither EGFR overexpression nor loss of PTEN expression (a very rare situation in our experience), patients will receive dasatinib (no randomisation). If the biopsy assessment is not contributive, the treatment will be allocated by randomisation between erlotinib, everolimus and dasatinib (R3 randomisation).

Diffuse pontine gliomas are incurable with currently used treatments. based on data stating that progressive tumors inhibit immune system, would try to enhance immune system activity and tumor cell killing. anti PD1 prevents one of the important mechanisms allowing the tumor to supress the immune system thus we hope it will allow for prolonged control of the tumors

This is a Phase II study in a single center to determine the efficacy of autologous dendritic cells (DCs) loaded with autogeneic glioma stem-like cells (A2B5+) administered as a vaccination in adults with glioblastoma multiforme (primary or secondary).

RATIONALE: Studying samples of blood in the laboratory from patients receiving temozolomide may help doctors learn how temozolomide works in the body. It may also help doctors learn more about how a patient's genes may affect the risk of developing thrombocytopenia. PURPOSE: This clinical trial is studying the pharmacokinetics in patients with newly diagnosed high-grade glioma receiving temozolomide and radiation therapy.
