Surgery for Recurrent Glioblastoma
Patients with glioblastoma face a grim prognosis. Despite recent advancement in neurosurgical technology and neuro-oncology glioblastomas almost invariably progress or recur after a median of 4-8 months. The strategy to repeat tumor resection at recurrence in order to minimize tumor load and thus to facilitate subsequent second-line therapy has been shown to be feasible and safe. However, evidence for a survival benefit of surgery for recurrent glioblastoma is scarce and relies entirely on retrospective analyses. While most retrospective analyses report an apparent survival benefit, an EORTC meta-analysis on second-line therapies found no...
Surgically Induced Neurological Deficits in Glioblastomas (SIND Study)
This study provides a work package for a larger programme of research developing Precision Surgery for Glioblastomas by developing individualised treatment volumes for surgery and radiotherapy. This study will recruit a cohort of patients with tumours in different brain regions and involve imaging pre- and post-operatively to outline the area of 'injury' to normal brain. The investigators will then correlate anatomical disruption with changes in measures of quality of life, visual functioning and visual fields and neuropsychology.
Surgical Tissue Flap to Bypass the Blood Brain Barrier in GBM
This study assesses the safety of using tissue autograft of a pedicled temporoparietal fascial (TPF) or pericranial flap into the resection cavity of newly diagnosed glioblastoma multiforme (GBM) patients. The objective of the study is to demonstrate that this surgical technique is safe in a small human cohort of patients with resected newly diagnosed GBM and may improve progression-free survival (PFS).
SYNERGY-AI: Artificial Intelligence Based Precision Oncology Clinical Trial Matching and Registry
International registry for cancer patients evaluating the feasibility and clinical utility of an Artificial Intelligence-based precision oncology clinical trial matching tool, powered by a virtual tumor boards (VTB) program, and its clinical impact on pts with advanced cancer to facilitate clinical trial enrollment (CTE), as well as the financial impact, and potential outcomes of the intervention.
Targeting Potassium Channels to Reprogram Glioblastoma Microenvironment: in Vitro and in Vivo Studies
The investigators want to verify the hypothesis that targeting the calcium-activated (KCa3.1) and the voltage-dependent K channel (Kv1.3) could be a valuable therapeutic strategy to reprogram cells of the innate immune system, with the aim to fight glioma, a deadly CNS tumor. The investigators will use murine models of glioma, injecting GL261 cells in the brain of syngeneic C57BL6 mice, to study the effect of K channel inhibition on the activation of microglia (M), macrophages (Mf) and NK cells. The investigators will use M and vesicles released from these cells, re-educated toward an anti-tumor phenotype, to interfere with the vicious...
Temozolomide Chronotherapy for High Grade Glioma
Temozolomide (TMZ) is the chemotherapy drug approved by the FDA to increase survival in glioblastoma (GBM) patients beyond surgical resection and radiation therapy alone. Give its activity in astrocytomas, TMZ is commonly used in grade III anaplastic astrocytoma (AA) as well. Both grade III AA and grade IV GBM are high grade gliomas (HGG). The short half-life of this drug and known oscillations in DNA damage repair make it an ideal candidate for chronotherapy. Chronotherapy is the improvement of treatment outcomes by minimizing treatment toxicity and maximizing efficacy through delivery of a medication according to the timing of...
Temozolomide Plus Anti-angiogenesis Drugs and Radiotherapy as a Treatment for Glioblastoma
Temozolomide (TMZ) is an oral chemotherapy drug. It is an alkylating agent used as a first-line treatment for glioblastoma. This methylation damages the DNA and triggers the death of tumor cells. According to the results of several clinical studies, TMZ synchronous plus radiotherapy and subsequent as adjuvant therapy can significantly improve the survival rate of newly diagnosed glioblastoma patients.
Temozolomide, Radiation Therapy, and Tumor Treating Fields Therapy in Treating Participants With Glioblastoma
This pilot early phase I trial studies the side effects of temozolomide, radiation therapy, and tumor treating fields therapy using Novo tumor treatment fields (TTF)-200A device in participants with glioblastoma. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. NovoTTF-200A device is a portable device that produces alternating electrical fields that may disrupt growth of cancer cells. Giving temozolomide,...
Testing Ramipril to Prevent Memory Loss in People With Glioblastoma
This study is to determine if an oral drug called Ramipril can lower the chance of memory loss in patients with glioblastoma getting chemoradiation. Patients will take Ramipril during chemoradiation and continue until 4 months post-treatment. Memory loss will be assessed using several neurocognitive tests throughout the duration of the study.
Testing the Ability of AMG 232 (KRT 232) to Get Into the Tumor in Patients With Brain Cancer
This phase I trial studies the side effects and best dose of MDM2 inhibitor KRT-232 in treating patients with glioblastoma (brain cancer) that is newly diagnosed or has come back (recurrent). MDM2 inhibitor KRT-232 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
