NCT00083447
TransMID treatment or best standard of care for patients with advanced glioblastoma multiforme Glioblastoma multiforme (GBM) is a type of brain tumour. GBM tumours are usually treated with surgery and radiotherapy. Unfortunately, this type of brain tumour may continue to grow or come back (recur) despite treatment. This trial will compare a new drug called TransMID with the best standard treatment that is currently available. TransMID is a drug that is a combination of a protein called transferrin and a poison called diphtheria toxin. Cancer cells need iron in order to continue to grow. They need more iron than normal cells. Transferrin helps cells to take up available iron. So the cancer cells are attached to the transferrin in TransMID, and the diphtheria poison kills them. The aim of this treatment is to kill the cancer cells while not affecting the normal brain cells. This treatment for brain tumours may have fewer side effects than other treatments because it targets cancer cells. The best standard treatment will involve giving chemotherapy. You may have chemotherapy as part of the treatment when you are diagnosed. Or it may be kept in reserve to treat your brain tumour if it comes back or continues to grow. Your cancer specialist (consultant) will decide which chemotherapy drugs you should have.
NCT00001573
A dose escalation scale consisting of 5 dosage levels is being used to determine the maximum tolerated dose (MTD) of SU101. A minimum of 3 and a maximum of 6 patients will be enrolled at each dose level. MTD is defined as the dose level immediately below that at which 2 or more patients exhibit dose limiting toxicity. Each treatment cycle is 21 days. Patients receive a 96 hour continuous IV infusion of SU101 on days 1-4.
NCT00059020
This study will examine tissue from gliomas (a type of brain tumor) removed during surgery for gene mutations, or changes, thought to be involved in tumor formation and growth. One common gene mutation causes the receptor for a protein called epidermal growth factor (EGF) to be in an active state all of the time, allowing uncontrolled cell growth that can lead to tumor formation. This study will analyze blood and tumor tissue samples from patients with gliomas for: * Changes in the EGF gene in the tumor * Changes in other genes, such as that for the EGF receptor (EGFR) * Changes in levels of EGF and EGFR, and in other proteins and genes that respond to changes in the levels of these proteins in the tumor * Changes in the EGF gene and protein in the blood The study will also determine if production of EGF and EGFR obtained from glioma and from blood cells derived from the tumor can be altered in the laboratory to grow indefinitely in culture. Patients between 18 and 75 years of age with a brain tumor that requires surgical treatment may be eligible for this study. Participants will be admitted to the NIH Clinical Center for about 3 to 10 days. They will have a physical and neurological examination, blood and urine tests, other tests, if medically necessary, and will be evaluated and prepared for surgery. During surgery, as much of the tumor as possible will be removed. A small amount of the tumor tissue will be collected for this study. No tissue will be removed for this study that would not otherwise have been removed. Some of the tissue will be used to culture glioma cells and the rest will be frozen and stored for examination, as described above. If any normal-appearing brain tissue is removed during surgery in order to enhance safety in removing the tumor, the normal tissue will be studied as well. Brain tissue that appears normal will not be removed strictly for research. During surgery and the day after surgery, a blood sample will be drawn from a catheter (plastic tube) that was placed in an artery or vein for surgery. If catheters are no longer in place, blood will be drawn through a needle in a vein.
NCT00006450
This study will examine the safety and effectiveness of treating brain tumors in children with a continuous infusion of phenylbutyrate. A breakdown product of this drug, phenylacetate, is normally found in low concentrations in the blood. At much higher concentrations, phenylbutyrate and phenylacetate are active against cancer in animals. Patients between 2 and 21 years old with a brain tumor that has progressed or recurred after radiation or chemotherapy, including bone marrow transplant, may be eligible for this study. Candidates will be screened with a medical history and physical examination, blood tests, magnetic resonance imaging (MRI) or computerized tomography (CT) of the head and, if needed, a spinal fluid test and bone marrow test. Study participants will have a continuous infusion of phenylbutyrate for two 28-day cycles-every day, 24 hours a day, 7 days a week. The medicine will be infused through a thin tube (catheter) placed in a large vein in the upper chest, delivered through a portable infusion pump. Patients will be hospitalized for at least 3 days when the treatment begins. If there are no side effects at that time, the infusions can continue on an outpatient basis. The patient or care giver will receive the medicine in 4-day supplies and will be taught how to change the bag and tubing daily for drug administration, as well as how to use the infusion pump. Patients will be monitored with weekly blood tests to look for side effects and measure blood levels of phenylbutyrate. They will have a physical examination at least once a week. At the end of the second 28-day cycle, patients will have a CT or MRI scan to evaluate the tumor's response to treatment. Patients whose tumor has grown will stop treatment and come off the study. Those whose tumor has remained stable or shrunk may continue phenylbutyrate as long as the treatment is beneficial and there are no serious side effects. CT or MRI scans will be done after every 2 cycles (or sooner if needed) to evaluate the treatment. Patients with certain tumor types (medulloblastoma, PNET, ependymoma, malignant germ cell tumor and pineoblastoma) or who have symptoms that indicate there might be tumor along the spinal cord may have a spinal tap. For this procedure, the patient lies on the side and a needle is inserted between two vertebrae (bones of the spine) in the lower back, into the cerebrospinal fluid space. A sample of fluid is drawn for testing for cancer cells. If the tumor has spread through the spinal fluid, a spinal tap will be done every other cycle (every 2 months) to monitor the effects of therapy.
NCT00001502
The presence of a highly selective blood-brain barrier (BBB) at the level of the brain capillary endothelium prevents chemotherapeutic agents from attaining therapeutic concentrations at the target site. RMP-7 is a synthetic bradykinin analog which specifically binds to B2 receptors expressed on the brain capillary endothelial cells and preferentially increases capillary permeability within CNS tumors. Carboplatin is an anticancer agent with preclinical and clinical antitumor activity against a variety of brain tumors. A pediatric phase I trial of the combination of RMP-7 and carboplatin will be conducted to determine the maximum tolerated dose of RMP-7 in children with refractory brain tumors.
NCT00505141
The Environmental Protection Agency has recognized that organophosphorus pesticides require close regulation and continued monitoring for human health effects and some (e.g chlorpyrifos) have been phased-out from the consumer market due to the special risk that it posed for children. There is growing evidence in support of the association between pesticide exposure and childhood leukemia. Studies of pesticides and their association with childhood cancer have been limited by study designs, self-reporting and lack of biological measurements. While several large studies in California found little evidence of an association between agricultural pesticide use and childhood leukemia, these results are in contrast with the associations observed with household exposures to pesticides. The real association may depend on timing of exposure, type of pesticide, dose and pathway of exposure. Furthermore, some persons may be more susceptible to the effects of specific pesticides due to inherited mutations in their detoxification pathways. We are conducting a pilot study to test the hypothesis that environmental exposure to pesticides in pregnancy or during the neonatal period, together with genetic susceptibility may lead to childhood ALL or brain cancer. The study is a multicenter, case-control study, based on collaboration between clinical researchers and basic science research to evaluate the risk for childhood cancer in relation to measured levels of pesticides (and their metabolites) and genetic polymorphisms. Biomarkers will be used to examine the risks of chronic low-dose exposures, and to characterize relationships between specific pesticides, childhood cancer and genetic susceptibility. Hypothesis: Interaction between environmental factors (pesticides) and maternal or child genetic polymorphisms may lead to childhood cancer.
