Study of VAL-083 in Patients With MGMT Unmethylated, Bevacizumab-naive Glioblastoma in the Adjuvant...
GliomaGlioblastoma3 moreThe purpose of this phase 2, two arm, biomarker-driven study is to determine if treatment of O-6-methylguanine-DNA methyltransferase (MGMT) unmethylated glioblastoma with VAL-083 improves overall survival (OS), compared to historical control, in the adjuvant or recurrent setting.
Clinical Trial of IV OKN-007 in a Pilot Cohort of Human Recurrent Malignant Glioma Patients
Recurrent Malignant GliomaThis is an open label Phase 1b clinical trial of IV administration of OKN-007 in a pilot cohort of human recurrent malignant glioma patients. All patients will have been previously treated with the standard-of-care treatment which includes surgical resection, radiation and chemotherapy, and in some cases treatment for recurrent disease with investigational agents or bevacizumab (Avastin). Patients with unequivocal recurrence (first or greater) established by MRI with and without contrast (e.g., Gd-DTPA (Gadolinium-diethylene triamine pentacetic acid) and meeting inclusion and exclusion criteria, will be eligible for OKN-007 treatment on this protocol.
Low-Dose or High-Dose Lenalidomide in Treating Younger Patients With Recurrent, Refractory, or Progressive...
Neurofibromatosis Type 1Recurrent Childhood Pilocytic Astrocytoma1 moreThis randomized phase II trial studies how well low-dose lenalidomide works compared with high-dose lenalidomide in treating younger patients with juvenile pilocytic astrocytomas or optic nerve pathway gliomas that have come back (recurrent), have not responded to treatment (refractory), or are growing, spreading, or getting worse (progressive). Lenalidomide is classified as an immunomodulatory drug as it boosts the immune system. It has other potential anti-tumor effects, for example, it may stop the growth of tumor cells by blocking blood flow to the tumor. It is not yet known whether low-dose lenalidomide is more or less effective than high-dose lenalidomide in treating patients with juvenile pilocytic astrocytomas or optic nerve pathway gliomas.
Virtual Biopsy Development to Identify Patient's Glioma Grade at the CHU of Poitiers Using Magnetic...
Development of the Virtual BiopsyTumor Grade3 moreGlioma is a tumor of the central nervous system. These lesions are sorted with the WHO ranking regarding the tumoral oncotype. The tumoral MRI assessment is the first step before any medical decision. Currently, only anatomical biopsy can give the tumor grade definition and help to define the most adapted treatment.
Feasibility Study of Modified Atkins Ketogenic Diet in the Treatment of Newly Diagnosed Malignant...
GlioblastomaThe purpose of this research study is to see if people can produce ketones in their blood with the modified Atkins diet. Modified Atkins diet is a diet that produces ketones in your blood by restricting carbohydrates to <20 grams per day. Ketones are substances that are produced in the blood when fat is being broken down. Ketones may help radiation work better and may starve your tumor because it is thought that some brain tumors can not use ketones to grow and can only use sugar or glucose to grow.
Evaluation of Diagnostic Performances of 18F-FDOPA PET KInetics
Gliomathe investigators hypothesise that 18F-FDOPA PET kinetic parameters are good biomarkers to characterise suspected LGG brain lesions that exhibit no contrast on MRI, for identifying aggressive lesions. These parameters could constitute diagnostic biomarkers for this indication. This new diagnostic tool could enhance patient care in the short term in an evolving pathology affecting socially active subjects with a poor prognosis
gliomasPCV Only in 1p/19q Codeleted Anaplastic Gliomas
Anaplastic Gliomas With 1p/19q CodeletionPatients with 1p/19q-codeleted anaplastic gliomas treated with RT + PCV are at risk of neurocognitive deterioration. Treating these patients with PCV alone (could reduce the risk of neurocognitive deterioration without impairing overall survival.
Analysis of Circulating DNA in Blood Samples of Glioma-affected Patients
GliomaCirculating Tumor CellThe present pilot study aims to investigate a new strategy in the liquid biopsy protocol for the diagnosis of gliomas based on the detection of circulating tumor DNA in the blood of patients with brain lesions compatible with this type of tumor. In order to increase the sensitivity of the technique, the investigators will work with raw blood samples through minimally invasive procedures. The subsequent analysis will be done with digital PCR, due to its low detection limit. The mutational results of each patient's samples will be compared with those obtained from the corresponding tissue biopsies. This step will allow the team to determine the robustness and reliability of the liquid biopsy. The grading of the tumor, as well as the confirmation of the diagnosis, will be obtained from the histological data. With the inclusion of more patients in the future, and with the optimization of the mutations investigated, the investigators want to standardize the protocol for the diagnosis of gliomas with liquid biopsy. This technique is less invasive than current surgical procedures used for diagnosis. In addition, using fewer hospital resources should allow a more accurate and rapid diagnosis of the pathology, and therefore, start the more personalized therapeutic stage earlier.
Magnetic Resonance Elastography in Glioma: Exploring Tumor Stiffness and Adhesion
Gliomathis study will investigate the relationship between tumor stiffness and adhesion in gliomas using MRE. By utilizing preoperative MRE and Intraoperative neuronavigation, followed by comprehensive molecular pathology analysis, we aim to explore the correlation of tumor stiffness and adhesion with molecular and genetic characteristics of gliomas. Additionally, the predictive value of MRE in terms of pathological staging and prognosis will be determined. This research may pave the way for improved clinical decision-making, personalized treatment approaches, and more accurate clinical trials for glioma patients.
CEST in Low-grade Glioma Study
Low-grade GliomaLow grade gliomas (LGGs) are malignant, infiltrative and incurable brain tumours that typically present in the younger population. This project proposes to use non-contrast metabolic "Saturation Transfer" (ST)-MRI to evaluate LGG tumour progression and aims to predict early changes in LGG. Early identification of LGG patients whose tumours will progress will permit early interventions. ST-MRI does not involve any intravenous injection of contrast and which acquires metabolic information not seen by standard MRI.
