Active clinical trials for "Glioblastoma"

Recently, ketogenic diet has been recognized a useful treatment strategy for glioblastoma in vitro. Therefore, the purpose of the study is to evaluate the safety and efficacy of ketogenic adjuvant to salvage chemotherapy for recurrent glioblastoma.

In this study the investigators will evaluate the effect of high-dose, intermittent sunitinib versus treatment with lomustine in patients with recurrent glioblastoma multiforme. The investigators hypothesize that sunitinib, when given in a high-dose, intermittent schedule, will achieve adequate concentration levels in the tumor and will, besides its anti-angiogenic properties, inhibit gliomagenesis by inhibition of multiple kinases.

Gliomas,especially high-grade glioma ,are the most common primary malignant brain tumor in adults,yet outcomes from this aggressive neoplasm remain dismal.The extent of resection is one of the most essential factors that influence the outcomes of glioma resection.However, conventional structural imaging has failed to accurately delineate glioma margins because of tumor cell infiltration. the investigators have finished few project that suggest the feasibility of Magnetic Resonance Spectrum(MRS)-guided resection,unfortunately, lacking sufficient clinical evidence.This prospective cohort study is to provide a clinical evidence for the validity of MRS-guided resection in patients with HGG .

The purpose of this study is to estimate the capacity of the multimodal imaging parameters measured at 15 days and 2 months of initiation of treatment with bevacizumab, to measure changes in clinical status (sensitivity to measure changes) in patients treated for recurrent glioblastoma.

Chimeric antigen receptor (CAR)-modified T cells can mediate long-term durable remissions in recurrent or refractory CD19+ B cell malignancies, and are a promising therapy to treat glioblastoma, which is the most dangerous and aggressive form of brain cancer. EGFRvIII mutation (epidermal growth factor receptor variant III, EGFRvIII) is the results of tumor specific gene rearrangement naturally happened in about 30% of glioblastoma patients and produces a mutated protein with neo-antigen that is tumor specific and is not expressed in normal human tissues. Therefore, EGFRvIII is an attractive target for CAR T cell therapy. We have constructed a lentiviral vector that contains a chimeric antigen receptor that recognizes the EGFRvIII tumor antigen. A truncated EGFR (tEGFR) which lacks of the ligand binding domain and cytoplasmic kinase domain of wildtype EGFR is incorporated into the CAR vector and is used for in vivo tracking and ablation of CAR T cells in necessary. This pilot study is to determine the safety and efficacy of autologous anti-EGFRvIII CAR T cells in patients with recurrent glioblastoma.

This study is designed to treat patients who have been diagnosed with brain cancer, including glioblastoma (GBM) and diffuse intrinsic pontine glioma (DIPG). The treatment uses immunomodulatory vaccine generated by autologous dendritic cells (DCs) pulsed with genetically modified tumor cells or tumor-related antigens including neoantigens to inject into patients. Vaccine-induced T cell responses have been associated with improved survival. The study will evaluate the safety and potential benefit of the novel immunomodulatory DC vaccines.

Hyperosmotic agents are used to decrease intracranial pressure. The aim of the study is to compare the effects of continuous 3% hypertonic saline (HS), bolus HS and 20% mannitol on intraoperative brain relaxation in patients with raised intracranial pressure during surgery for supratentorial tumors.

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, radiation therapy, and tumor treating fields therapy using NovoTTF-200A device may work better in treating participants with glioblastoma.

Background Currently, no standard treatment exists for patients with recurrent glioblastoma multiforme (rGBM) and used 2nd line treatments have low (up to max. 20%) response rates and very modest response duration (months). The median overall survival for GBM patients is 12-14 months from the time of diagnosis; therefore the development of new therapeutic options is imperative. HU has been used to treat hematological diseases and solid tumors (such as melanoma, ovarian, squamous cell carcinoma, head and neck carcinoma and brain tumors) in combination with other anti-cancer agents, but never with TMZ. If found safe, HU+TMZ, is easily translated to the clinic. Purpose: Phase I trial to identify the maximum tolerated dose (MTD) for the combination of dose intense temozolomide (TMZ) and hydroxy-urea (HU) in (maximal) thirty patients with recurrent glioblastoma (rGBM). Plan of investigation: Month 0-24 (1st and 2nd year): Inclusion and follow-up of a maximum of 30 patients with rGBM Month 25-31 (3rd year): Follow-up of patients included in the trial, data analysis (determining MTD and explorative analysis) and manuscript preparation. Possible results: Obtaining MTD and safety profile of daily HU+TMZ in patients with rGBM; Preliminary data on the estimation of the median progression-free (PFS) and overall survival (OS), radiographic response proportion in patients with measurable disease, and exploratory correlation of treatment outcomes (PFS and OS) with o6-methylguanine-DNA-methyltransferase (MGMT) promoter methylation status in archival tumor specimens and further elucidation of underlying mechanism of re-sensitization of TMZ by HU. Exploratory analysis of biomarkers profile of platelets in patients treated with HU+TMZ.

This is a prospective, open-label, single arm, historical control pilot study aimed to test the effectiveness and safety of TTFields delivered through high intensity arrays in recurrent glioblastoma. The Optune® System is an investigational , portable, battery operated medical device in this study delivering 200 kHz TTFields to the brain using high intensity transducer arrays for the treatment of patients at the age of 18 years or older with first or second recurrence of Glioblastoma Multiforme (GBM)
