Active clinical trials for "Glioblastoma"

The study seeks to assess the response of glioblastoma multiforme to treatment using weekly low field (0.35 T) MR-images of the brain at a MRIdian® linac system during standard radiotherapy at the same system. A total of 20 patients in a single arm will be recruited for this investigation. The imaging data will be used to evaluate the change in tumor volume over the course of the treatment and to perform radiomics in order to investigate the possibility of response prediction using these images. In order to assure sufficient image quality, prior to the main investigation, a group of up to 20 volunteers has MR scans taken with identical sequences to the main study phase.

This is a restrospective study to establish a deep learning model based on multi-parametric magnetic resonance imaging scans to predict Grade, histopathologic type and genotype of adult diffuse Glioma.

To learn how altered metabolism in GBM causes tumor growth and resistance to drug therapy. In this pilot research study, we will dose GBM patients with a form of nicotinamide (a natural vitamin) that we can track. The nicotinamide will be converted to methyl nicotinamide (MeNAM) in the tumor. We will measure how fast the nicotinamide is converted to methyl nicotinamide. We believe that the speed of this chemical reaction in the tumor (fast versus slow) may be correlated with GBM aggressiveness

Patients with glioblastoma, an aggressive brain tumor, are recommended to undergo treatment with tumor treating fields using the Optune device as part of standard of care therapy. While undergoing treatment, patients are monitored regularly with brain MRI scans to look for tumor progression, but there are currently no means to predict which, or when, patients will progress. The purpose of the current study is to prospectively analyze these MRI scans to look for subtle imaging markers that can predict for future brain tumor progression while undergoing tumor treating field therapy.

This study examines tumor tissues and blood samples to aid in the development of therapies for brain cancer and other solid tumors. Studying samples of blood and tissue from patients with glioblastoma or other solid tumor in the laboratory may help doctors understand brain tumors and better inform future treatments.

Glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA) are the most common primary malignant brain tumors. Survival of patients with these brain tumors is directly related to the extent of resection. Consequently, a great deal of effort has been directed at developing techniques and technologies that allow more extensive, safe resections. This study will test a loupe-based wearable device in the clinical setting and compare its accuracy with a large operative microscope to identify tumor tissues. Postoperative histopathological analysis on tumor tissues will be used as gold standards for comparison. The outcome from this study will be a low-cost, miniaturized, easy-to-operate, loupe-based fluorescence imaging device for intraoperative guidance of brain tumor resection with the same level of accuracy as the large microscope.

Glioma is the most common primary malignant brain tumour in adults and has an extremely poor prognosis. Glioblastoma is the most common subtype and its most aggressive form, with an annual incidence of 3.19 cases per 100,000. The aim of this study is to quantify the degree of fatty acid oxidation in 20 participants diagnosed with glioblastoma multiforme (GBM) that have undergone surgical resection throughout the course of their chemotherapy and radiotherapy treatment. The investigators hypothesise that the parameters derived from longitudinal 18F-fluoropivalate (18F-FPIA) positron emission tomography (PET) will change predictably over the course of therapy in relation to response.

The aim is to improve patients' compliance to TTFields therapy by a psychological video intervention in a multi-center, randomized controlled trial.

The goal of this prospective, non-randomized, single-arm study is to evaluate the safety and feasibility of sonodynamic therapy with 5-aminolevulinic acid in patients with newly diagnosed cerebral glioblastomas using the ExAblate Model 4000 Type-2 "Neuro-System". Patients will be consented, screened, and will undergo study SDT treatment with 5-ALA using the ExAblate Model 4000 Type-2 "Neuro-System". After SDT treatment, patients will perform a strict neuro-radiological follow-up (minimum of 2 MRI) and undergo tumor resection 15-21 days after SDT, according to the clinical and radiological status. The main goal of the present study is to investigate the safety and feasibility of SDT in patients affected by GBMs attained with low-frequency FUS. In particular: Safety will be evaluated by patient examination and MRI images during the treatment, and by follow-up MRI and clinical and neurological visits. To evaluate feasibility, the extent of the sonicated area will be calculated at the end of the procedure in order to evaluate the targeted area. Secondary objective of the trial is to assess the efficacy of the SDT procedure in terms of tumor regression and/or cell apoptosis and necrosis.

The goal of this Phase 0 trial is to study if pre-operative oral pitavastatin administration reaches the tumour in patients with primary or a recurrent glioblastoma. The main question[s] it aims to answer are: Does pitavastatin reach a cytotoxic concentration in gadolinium-enhanced tumour tissue after oral administration? Does pitavastatin achieve a concentration that can synergize with temozolomide in the gadolinium non-enhanced area of the tumour? Participants will receive pitavastatin in differing dosages a week before their elective surgery and blood and tumour samples will be collected.
