Filter by:This is a single center Phase I study to determine the safety and maximum tolerated dose (MTD) of autologous dendritic cells (DCs) loaded with allogeneic brain tumor stem cells administered as a vaccination in children and adults with recurrent brain tumors. Once the MTD has been determined, we will conduct a phase II study to determine efficacy. Clinical trials that utilize DCs for immunotherapy have demonstrated significant survival benefit for patients who exhibit robust immune responses against tumor cells. Unfortunately, at the present time the majority of tumor patients are unable to mount an adequate immune response and thus succumb to their tumors. We postulate that the inability to generate an appropriate immune response in these patients is due to a lack of sufficient numbers of appropriate T cells due to an inadequate source of tumor antigens.
Background: - Pazopanib, a drug that inhibits the growth of new blood vessels in tumors, was recently approved by the Food and Drug Administration to treat advanced kidney cancer in adults. Pazopanib has been used in only a small number of adults, and more research is needed on whether it is safe and effective to use in children. Researchers are interested in determining safe and effective treatment doses of pazopanib in children, and in other studies will examine which form of pazopanib treatment (tablet or liquid) is most effective and well tolerated. Objectives: - To determine a safe and effective dose of pazopanib to treat solid tumors in children. - To study the effects of pazopanib on blood cells, blood flow, and human development. Eligibility: - Children, adolescents, and young adults between 1 and 21 years of age who have been diagnosed with solid tumors that have not responded to treatment. Design: - Eligible participants will be screened with a physical examination, blood and tumor samples, and imaging studies. - Participants will receive pazopanib tablets for 28-day cycles of treatment. Pazopanib should be taken on an empty stomach, at least 1hour before or 2 hours after a meal. Participants may receive pazopanib for up to 24 cycles unless the tumor does not respond or participants develop serious side effects. - Blood samples will be taken on days 1, 15, 22, and 27 of the first cycle of pazopanib, with additional samples taken every 8 weeks during subsequent cycles. - An optional part of the study will collect additional blood samples at regular intervals for 24 hours after the first dose of pazopanib and at regular intervals after another dose during the second or third week of the first treatment cycle.
The purpose of this research is to explore the factors involved in brain cancer health care literacy needs.
Certain kind of neurosurgical procedures require intraoperative alertness of the patient, for example to perform speech tests during brain tumor resection. With respect to anaesthesia, it is therefore required that the patient is asleep during the beginning and the end of the procedure, however fully awake in between. To do so, the anaesthetic propofol is used and an accurate knowledge of its pharmacokinetic and -dynamic (pk/pd) parameters is required to optimally control anaesthesia. However, diverse pk/pd-parameter sets have been described in the literature. The aim of the study is to investigate whether the pk/pd model proposed by Marsh et al. or by Schnider et al. more accurately describe the pk/pd of propofol during awake craniotomy.
The purpose of this study is to culture primary human brain tumor cells with the specific aims of: 1. Develop primary cultures from human brain tumor surgical specimens 2. Determine the genetic and molecular fingerprints of brain tumors that may have prognostic significance 3. Delineate the mechanisms underlying oncogenesis of brain tumors. 4. Perform in vitro assays with brain tumor derived primary cultures to assess the efficacy of novel therapeutic agents.
The purpose of this study is to evaluate the safety and tolerability of oral Dichloroacetate (DCA) in the treatment of recurrent malignant brain tumors (RMBTs). RMBTs are defined as either: 1) malignant tumors, originating in the brain, that have recurred at least once or 2) malignant tumors originating elsewhere in the body that have spread to the brain at least once. Otherwise, there are no limitations to the number of prior recurrences. There are no limitations to the number or types of prior therapies.
Two studies (Gerlach et al. 2000; Gerlach et al. 2002) described the impact of factor XIII on the risk of prospective hemorrhage for patients undergoing craniotomy. Since then, factor XIII is measured and substituted in various centers. Few reports support the idea of factor XIII being involved in the formation of deep venous thrombosis and pulmonary embolism. In this prospective observational study, patients undergoing craniotomy for brain tumors or vascular lesions are investigated concerning the incidence of postoperative pulmonary embolism in respect of possible risk factors (factor XIII activity levels, standard coagulation parameters, tumor entity, blood loss).
RATIONALE: Ritonavir and lopinavir may stop the growth of gliomas by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying how well giving ritonavir together with lopinavir works in treating patients with progressive or recurrent high-grade glioma.
RATIONALE: Radiosurgery can send x-rays directly to the tumor and cause less damage to normal tissue. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of glioblastoma by blocking blood flow to the tumor. Drugs used in chemotherapy such as irinotecan hydrochloride work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiosurgery together with bevacizumab and irinotecan hydrochloride may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving radiosurgery together with bevacizumab and irinotecan hydrochloride works in treating patients with recurrent glioblastoma.
RATIONALE: Biological therapies, such as cellular adoptive immunotherapy, may stimulate the immune system in different ways and stop tumor cells from growing. Donor T cells that are treated in the laboratory may be effective treatment for malignant glioma. Aldesleukin may stimulate the white blood cells to kill tumor cells. Combining different types of biological therapies may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best way to give therapeutic donor lymphocytes together with aldesleukin in treating patients with stage III or stage IV malignant glioma.
