Filter by:The purpose of this research study is to determine if an investigational dendritic cell vaccine, called pp65 DC, is effective for the treatment of a specific type of brain tumor called glioblastoma (GBM) when given with stronger doses of routine chemotherapy.
Glioblastoma (GBM) accounts for approximately 50% of all glioma and among these tumors, are the most malignant. The cells of origin of glioma are still undefined, but the most putative target cells include astrocytes, neural stem cells, and oligodendrocyte precursor cells. The current standard of care for patients with newly diagnosed GBM includes temozolomide and radiotherapy . Melanocortins are peptides with well-recognized anti-inflammatory and neuroprotective activity. Of the five known melanocortin receptors (MCRs), only subtype 4 is present in astrocytes and it is expressed predominantly in the brain. No data are currently available on MC4R gene polymorphisms and gliomas or their relationship with radiotherapy or chemotherapy. Aim. Given the association of MC4R with antiinflammatory activity, neuroprotection, induction of neural stem/progenitor cell proliferation in brain hypoxia, and prevention of astrocyte apoptosis, the aim of this study is to retrospectively evaluate the possible prognostic/predictive role of the MC4R SNPs on GBM therapy.
This study is a clinical trial to determine the safety of injecting G207 (a new experimental virus therapy) into a recurrent or progressive brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication and tumor cell killing, will also be tested.
This phase I trial studies the side effects and the best dose of wild-type reovirus (viral therapy) when given with sargramostim in treating younger patients with high grade brain tumors that have come back or that have not responded to standard therapy. A virus, called wild-type reovirus, which has been changed in a certain way, may be able to kill tumor cells without damaging normal cells. Sargramostim may increase the production of blood cells and may promote the tumor cell killing effects of wild-type reovirus. Giving wild-type reovirus together with sargramostim may kill more tumor cells.
This research study is studying the changes in primary and metastatic brain tumor inflammation using positron emission tomography (PET) imaging using a radioactive substance called [11C] PBR28a, which is also known as peripheral benzodiazepine receptors (PBR), or PBR-PET.
The purpose of this study is to test a new imaging agent called 89Zr-J591 (stands for humanized antibody called J591, that is attached to a radioactive material called Zirconium-89) in patients with glioblastoma multiforme.
The purpose of this study is to determine whether the combination of two agents, INC280 and bevacizumab, is safe and effective when administered to patients with Glioblastoma Multiforme (GBM) who have progressed after receiving prior therapy or who have unresectable GBM.
Standard treatment of glioblastomas (GBMs) consists of microsurgical resection followed by concomitant chemoradiation. The extent of resection is one of the most important prognostic factors with significant influence on the survival of patients. State of the art technique to achieve the most radical resection possible in conventional surgery is fluorescence-guidance with 5-aminolevulinic acid (5-ALA). If available, intraoperative MRI (iMRI)-guided tumor resection enables an intraoperative resection control and subsequent continuation of surgery if contrast enhancing tumor remnants are found. Therefore a more radical resection and longer survival of patients might be possible. To date no comparison of these two leading technologies for GBM-surgery is available to identify the best surgical therapy of this fatal disease and to justify significant healthcare-economic differences between both technologies. Goal of this study is to assess the value of iMRI guidance in the resection of GBMs in comparison to conventional 5-ALA microsurgery. Primary endpoint is the number of total resections (no residual contrast enhancement) in the postoperative MRI (T1+CM within 48 hours after surgery) in each group. Secondary endpoints are perioperative clinical data, progression free survival, patients' clinical condition and overall survival. The study design was chosen to be a parallel-group approach to compare iMRI and 5-ALA centers (n=13) to exclude possible bias which might be found by randomizing patients within individual iMRI centers and to have surgeons with the most experience possible in use of each respective technology.
Patients with a glioblastoma (GBM) have a poor prognosis with a median survival of 14.6 months after maximal treatment with a resection and chemoradiation. Since the pivotal trial evaluating the effect of temozolomide (TMZ), overall survival has not increased. Treatment of GBM xenografts in vivo with chloroquine (CQ), an antimalarial agent, has been shown to reduce the hypoxic fraction and sensitizes tumors to radiation. Epidermal growth factor receptor (EGFR) amplification or mutation is regularly observed GBM and is thought to be a major contributor to radioresistance. The most common EGFR mutation in GBM (EGFRvIII) is present in 50-60% of patients whose tumor shows amplification of EGFR. EGFR provides cells with a survival advantage through autophagy when exposed to stresses such as hypoxia and nutrient starvation. This effect is even more pronounced in EGFRvIII overexpressing tumors. Previously, the potential effect CQ has been demonstrated in a small randomized controlled trial in GBM treated with radiotherapy and carmustine, which showed a trend towards increased overall survival. However, as the intracellular effects of chloroquine are dose-dependent the maximum tolerated dose for CQ in combination with concurrent radiotherapy with daily temozolomide needs to be established.
The goal of this study is to increase and improve Goals of Care discussions for advanced cancer patients by training medical oncologists to conduct these discussions. The investigators will evaluate the GoC discussion's effects on patient satisfaction, receipt of treatment in line with preferences, use of aggressive treatment, and oncologist communication skill.
