Filter by:This is a dose-escalation study that will assess the safety and determine the maximum tolerated dose (MTD) of mibefradil dihydrochloride, a partially selective T-type calcium channel blocker, combined with hypofractionated radiation therapy (RT) in subjects with recurrent glioblastoma multiforme (GBM).
The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), comprise the majority of all primary brain tumors in adults. Initial therapy consists of either surgical resection, external beam radiation or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). Superselective Intraarterial Cerebral Infusion (SIACI) is a technique that can effectively increase the concentration of drug delivered to the brain while sparing the body of systemic side effects. One currently used drug called, Cetuximab (Erbitux) has been shown to be active in human brain tumors but its actual CNS penetration is unknown. This phase I clinical research trial will test the hypothesis that Cetuximab can be safely used by direct intracranial superselective intraarterial infusion up to a dose of 500mg/m2 to ultimately enhance survival of patients with relapsed/refractory GBM/AA. By achieving the aims of this study the investigators will determine the the toxicity profile and maximum tolerated dose (MTD) of SIACI Cetuximab. The investigators expect that this study will provide important information regarding the utility of SIACI Cetuximab therapy for malignant glioma, and may alter the way these drugs are delivered to the investigators patients in the near future.
This study is for patients that have a type of brain cancer called glioblastoma multiforme (GBM). The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise, but have not been strong enough to cure most patients. The antibody used in this study is called anti-HER2 (Human Epidermal Growth Factor Receptor 2). This antibody sticks to GBM cells because of a substance on the outside of these cells called HER2. Up to 80% of GBMs are positive for HER2. HER2 antibodies have been used to treat people with HER2-positive cancers. For this study, the HER2 antibody has been changed so that instead of floating free in the blood it is now attached to T cells. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These chimeric receptor-T cells seem to be able to kill tumors like GBM, but they don't last very long and so their chances of fighting the cancer are limited. Therefore, developing ways to prolong the life of these T cells should help them fight cancer. We found that T cells work better if we also attach a protein called CD28 to the HER2 chimeric receptor (HER2-CAR). In this study we placed this HER2-CAR into T cells that were pre-selected for their ability to recognize Cytomegalovirus (CMV). This virus exists in most people. These CMV-specific cytotoxic T cells (CMV-T cells) will be more active since they will react to the virus as well as to tumor cells. These HER2-CD28 CMV-T cells are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to find the largest safe dose of HER2-CD28 CMV-T cells, to learn what the side effects are, and to see whether this therapy might help patients with GBM.
