Filter by:This is a phase 1b study for safety and tolerability of bevacizumab(Avastin)administered into the tumor resection cavity in subjects with Glioblastoma Multiforme (GBM) at first recurrence.
The purpose of this study is to determine whether the addition of an investigational medication, axitinib, to radiation therapy will improve the outcome of treatment in patients, above the age of 70.
In this study subjects will be administered a single oral dose of Aminolevulinic Acid (ALA) prior to surgical resection of their brain tumor. The ALA ultimately causes brain tumor tissue to fluoresce or light up under ultraviolet light. During surgery an ultraviolet light in the microscope chain will be turned on. The tumor tissue will fluoresce bright pink allowing the surgeon to more easily differentiate tumor tissue from normal brain tissue. The aim of the study is to determine whether ALA and fluorescent visualization of tumor tissue improves the surgeon's ability to completely resect or remove the brain tumor.
Background: - The blood-brain barrier helps to protect the central nervous system (brain and spinal cord) from harmful toxins, but also prevents potentially useful chemotherapy from reaching brain tumors. The barrier is formed by tight connections between blood vessel cells and molecules found on the surface of brain blood vessels such as Permeability-glycoprotein (Pgp). Pgp may influence whether patients with brain tumors known as gliomas respond to chemotherapy and what side effects they may experience. The compound (11C)N-desmethyl-loperamide ((11C)dLop) reacts to Pgp molecules, and therefore may be used with positron emission tomography (PET) imaging to study the blood brain barrier. Objectives: - To study the ability of PET imaging with (11C)dLop to evaluate the blood brain barrier in brain tumor patients. Eligibility: - Individuals at least 18 years of age who have a brain tumor with characteristics that may be imaged with techniques such as magnetic resonance imaging (MRI) andPET. Design: - Participants will be screened with a full physical examination and medical history, blood and urine tests, and tumor imaging studies (fluorodeoxyglucose PET and MRI scans with contrast agent). - The (11C)dLop scan will take 1 hour to perform. Participants will be asked to return for blood and urine tests approximately 24 hours after the PET scan. - Participants will have followup visits at least every 4 months by repeating a complete history and physical exam and brain MRI. Participants may have repeat scans with (11C)dLop at various points in the course of cancer treatment, but will not have these scans more than twice in a 12-month period. - Participants will be followed for as long as possible during treatment to see if imaging with (11C)dLop correlates with response to the treatments.
Patients have a type of brain cancer called glioblastoma multiforme. Because most GBMs come back after standard therapy, patients are being asked to volunteer to take part in a research study using special immune cells. They may have already thought about being in this study. Some patients with GBM show evidence of infection with a virus called Cytomegalovirus before the time of their diagnosis. CMV is found in the cancer cells of some patients with GBM, suggesting that it may play a role in causing the disease. The cancer cells infected by CMV are able to hide from the body's immune system and escape destruction. We want to see if special white blood cells, called T cells, that have been trained to recognize and kill special parts of CMV infected cells can survive in the blood and affect the tumor. We have used this sort of therapy to treat different types of cancer that are positive for other viruses and have had variable results. Some patients have had responses others did not. It is not possible for us to predict if this treatment will work for GBM. The purpose of this study is to find the largest safe dose of CMV-T cells, to learn what the side effects are, and to see whether this therapy might help patients with GBM.
The purpose of this study is to determine the safety and effectiveness of Gliadel wafers at the time of surgery, followed by the combination of radiation, Temodar, and Avastin, and then the combination of Avastin and Temodar, after radiation is complete, on malignant brain tumors. About six weeks after surgery, subjects will begin standard radiation therapy, a fixed dose of Avastin every 2 weeks, and daily Temodar for the six and a half weeks of radiation. Beginning 2-3 weeks after the last radiation therapy, subjects will be given the same fixed dose of Avastin intravenously (through the vein) every 14 days. They will also be given a higher dose of oral Temodar to take daily the first 5 days of each 28-day study cycle.
Phase I Objectives: -To determine the maximum tolerated dose (MTD) of vorinostat + erlotinib versus vorinostat + erlotinib + temozolomide in adult patients with recurrent glioblastoma multiforme (GBM) and anaplastic gliomas. Phase II Objectives: Primary: To determine the efficacy of vorinostat + erlotinib versus vorinostat + erlotinib + temozolomide in patients with recurrent glioblastoma multiforme as progression free survival using a two arm adaptive randomization phase II trial design. Secondary: To determine the radiological response, progression free survival (PFS) at 6 months, overall survival and unexpected toxicity in the two treatment arms; and to obtain exploratory data regarding histone 3 and 4 acetylation, treatment related changes in the epidermal growth factor receptor (EGFR) pathway proteins, and changes in e-cadherin and vimentin expression (mRNA /protein) levels in tumor tissue and peripheral monocytes in a subset of surgical patients.
Current treatments for Glioblastoma Multiforme (GBM), the most common and malignant primary brain tumor are inadequate and as such, the median survival for most patients with GBM is on the order of months, even after cytoreductive surgery, radiation and chemotherapy. This study aims to develop a new treatment for GBM by suppressing glial progenitor cells that surround the ventricular system in patients with these aggressive tumors because it is these regions that appear to act as an incubator for future recurrences resulting in patient death. Considering the lack of significant treatment options for patients with this uniformly fatal disease, this is an important translational clinical study to perform.
The primary purpose of this study is to determine the safety and efficacy of the infusion of partially matched, allogeneic, CMV specific cytotoxic T cells (CTL) for patients with GBM that have failed primary therapy.
Background: One way tumors are able to grow is by forming new blood vessels that supply them with nutrients and oxygen. Sunitinib blocks certain proteins on the surface of tumor and blood vessel cells that are involved with the formation of new blood vessels. Blocking these proteins may prevent the tumor cells or blood vessels from continuing to grow. Objectives: To determine whether sunitinib can cause tumors to shrink or stabilize in patients with recurrent brain cancer. Eligibility: Patients 18 years of age or older with brain cancer whose disease has worsened after standard treatment with surgery, radiation. Design: Patients take a sunitinib pill once a day in 4-week treatment cycles. Treatment may continue as long as the tumor remains stable or decreases in size and the side effects of treatment are tolerated. Routine blood tests are done every 2 weeks during the first 8 weeks of treatment and then every 4 weeks after that. Magnetic resonance imaging (MRI) scans are done before starting treatment (at baseline) and at the end of every 4-week cycle to monitor tumor growth. Positron emission tomography (PET) scans are done at baseline and at the end of the first cycle. Neurological and physical examinations are done at baseline, at week 2 of treatment and at the end of every treatment cycle. Health-related quality of life is assessed every 4 weeks. Pregnancy tests, electrocardiograms and echocardiograms are repeated as needed.
