Filter by:This is a prospective, single-arm, two stages, open-label, pilot study to investigate the efficacy and safety of FUS add-on bevacizumab (BEV) in rGBM patients. The BEV is the best physician's choice of standard of care for rGBM after prior radiotherapy and temozolomide chemotherapy in the LinKou Chang Gung Memorial Hospital. Eligible patients will be enrolled through the process of informed consent.
Background: Diffuse low-grade gliomas (DLGG) are slow-growing primary-cancer of the brain and spinal cord. They represent up to 15% of the developing tumors in those organs with fatal outcome for the patients because of their evolution. The reasons for this transformation towards more malignant tumors still remain ill defined. Previously, the research team in neuro oncology at Montpellier University Hospital found foci of tumor heterogeneity within 20 to 30 % of the patients developing a DLGG and published their results. The investigators assumed that those foci represent the early beginning of the transformation from a diffuse low-grade glioma to a glioblastoma, tumor with highly malignant cells and a life expectancy of two years in average for the patient. Methods: The investigators selected adult patients with no prior surgery nor neuro oncology treatment when enrolled. They presented a specific mutation for an enzyme of the metabolism named IDH1, standing for Isocitrate Dehydrogenase 1, found in 70% of DLGG. Patients were also selected because they presented foci of tumor heterogeneity. After obtaining their consent, the investigators studied by immunohistochemistry the pathways deregulated between the DLGG and the foci. The investigators also extracted RNAs, molecules expressing the life and metabolism of tumor cells, and compared them to know what genes were differentially expressed between the DLGG and the foci. All RNAs were tested for quality control prior to be processed further. The investigators then studied 8 patients with compliance with ethics, authorizations and institutional guidelines. Genes of interest were studied in vitro to assess their functions. The investigators found a barely described enzyme of the catabolism of the phosphoethanolamines and discovered a new anti-proliferative tumor-role for it. •Discussion: The investigators first showed that foci have a higher percentage of p-STAT3+ cells which indicates STAT3 pathway activation in these cells. Phosphorylated STAT3 translocates to the cell nucleus to regulate many genes involved in proliferation, apoptosis and angiogenesis. As such, phosphorylation of STAT proteins, notably STAT3, is involved in the pathogenesis of many cancers, including GBM, by promoting cell cycle progression, stimulating angiogenesis, and impairing tumor immune surveillance. The investigators found that ETNPPL RNA and protein are reduced in foci cells and absent in glioblastomas. This is consistent with glioma database analyses showing that ETNPLL expression is inversely correlated to STAT3 and MKI67 whose expression are higher in foci and glioblastomas. In addition, Kaplan-Meier analysis shows that patients with low expression of ETNPPL have lower overall survival These observations suggested that this enzyme may oppose glioma cells proliferation. The investigators demonstrated this hypothesis by overexpressing ETNPPL in 3 glioblastoma cell cultures. Two were sensitive to ETNPPL overexpression which reduced their growth while no effect was detected in Gli4 cells. These glioblastoma-derived cultures have different types of mutations.
Retrospective longitudinal follow-up in patients with diffuse low-grade glioma with multimodal MRI assessment
The blood brain barrier (BBB) prevents some drugs from successfully reaching the target source. Convection-Enhanced Delivery (CED) is a method of direct infusion of drugs under controlled pressure to the tumor that may reduce systemic side effects of drugs in the patient. The purpose of this Phase I study is to find the maximum tolerated dose of MTX110 (a water-soluble Panobinostat nanoparticle formulation) and Gadolinium that can be given safely in children with newly diagnosed diffuse midline gliomas. All patients enrolled in the study will receive infusion of MTX110 and Gadolinium delivered with a pump directly into the tumor over 9-11 days.
This study evaluates the safety associated with the addition of sulfasalazine to stereotactic radiosurgery for recurrent glioblastoma. Sulfasalazine is a potential tumor selective radiosensitizer.
This is a pilot study to assess the ability of [F-18]fluciclovine to differentiate pseudoprogression from progression in participants after therapy, at imaging time points within the 12 week interval post chemoradiation. [F-18]fluciclovine. PET will be obtained at the time point in the 12 week interval in which MRI demonstrates increase in enhancing volume with the differential diagnosis of pseudoprogression versus tumor progression. At the same time point (at least 6 hours after [F-18]fluciclovine or up to 3 days) F-18 FDG will also be performed consistent with standard clinical practice. The verification of pseudoprogression versus tumor progression will be determined by the regression of enhancing lesion on subsequent MRI imaging obtained as part of standard care.
This study is testing a supportive psychosocial intervention for caregivers of people who have malignant brain tumors such as gliomas or other high-grade primary brain tumors. This study was designed because caregivers of patients with malignant brain tumors often experience physical and psychological burdens caring for their loved ones. The purpose of this study is to find out whether a program offering psychological support can help caregivers learn effective coping methods during their loved one's treatment and make the experience of being a caregiver more manageable.
Glioma is the most common primary malignant brain tumour in adults and has an extremely poor prognosis. The aim of this study is to quantify the degree of early step fatty acid oxidation in gliomas as imaged by 18F-FPIA PET/MRI in 10 evaluable patients. The Investigators hypothesise that FPIA uptake will be higher in high-grade gliomas compared to lower grade gliomas, in keeping with a higher propensity of high grade tumours to generate ATP and NADPH via fatty acid oxidation under bioenergetic stress.
The purpose of this pilot study is to determine the safety, tolerability, and the maximum tolerated dose intranasal administration of temozolomide (TMZ) as a single agent in Treatment on the patients with GBM. Intranasal administration is a new method of treating brain tumours for the direct administration of drugs, inhibitors or viruses, with minimal involvement of the BBB. The investigators know the orally prescribed standard chemotherapy temozolomide (TMZ) is widely used to treat glioma tumours. Received evidence of safety and efficacy in a full cycle of preclinical trials (on GLP Standart) and tests of calculated doses of intranasal administration of TMZ in healthy volunteers. Intranasal administration of temozolomide is considered as GBM therapy, which provides direct access to a therapeutic dose of the drug into the brain (to the neoplastic process) with low toxicity
This is a Phase 1 dose-escalation study of PRT811, a protein arginine N-methyltransferase (PRMT) 5 inhibitor, in subjects with advanced cancers and high-grade gliomas who have exhausted available treatment options. The purpose of this study is to define a safe dose and schedule to be used in subsequent development of PRT811.
