Filter by:RATIONALE: Genetically-modified neural stem cells (NSCs) that convert 5-fluorocytosine (5-FC) into the chemotherapy agent 5-FU (fluorouracil) at sites of tumor in the brain may be an effective treatment for glioma. PURPOSE: This clinical trial studies genetically-modified NSCs and 5-FC in patients undergoing surgery for recurrent high-grade gliomas.
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.
This is a multicenter, open-label, ascending-dose trial of the safety and tolerability of increasing doses of Toca 511, a Retroviral Replicating Vector (RRV), administered to patients with recurrent high grade glioma (rHGG) who have undergone surgery followed by adjuvant radiation therapy and chemotherapy. Patients will receive Toca 511 either via stereotactic, transcranial injection into their tumor or as an intravenous injection given daily for 3 & 5 days, depending on cohort. Approximately 3-4 weeks following injection of the RRV, treatment with Toca FC, an antifungal agent, will commence and will be repeated approximately every 6 weeks until study completion. After completion of this study, all patients will be eligible for enrollment and encouraged to enter a long-term continuation protocol that enables additional Toca FC treatment cycles to be given, as well as permits the collection of long-term safety and survival data.
RATIONALE: Pioglitazone hydrochloride may be effective treatment for cognitive dysfunction caused by radiation therapy. PURPOSE: This phase I trial is studying the side effects and best dose of pioglitazone hydrochloride in preventing radiation-induced cognitive dysfunction in treating patients with brain tumors.
The purpose of this research study to determine if treating recurrent malignant gliomas with another person's (donor) immune system cells known as aCTL cells, will be safe. This study will also try to determine if persons who receive aCTL's are more or less likely to survive their brain tumor than persons who had similar tumors in the past. Approximately 15 patients will be enrolled at UCLA.
This phase I clinical trial is studying the side effects and best dose of giving gamma-secretase inhibitor RO4929097 and cediranib maleate together in treating patients with advanced solid tumors. Gamma-secretase inhibitor RO4929097 and cediranib maleate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cediranib maleate also may stop the growth of tumor cells by blocking blood flow to the tumor.
Phase I dose-escalation study to characterize the safety, tolerability, pharmacokinetics and pharmacodynamics of LDE225 given orally on a daily dosing schedule in children with recurrent or refractory medulloblastoma, or other tumors potentially dependent on Hedgehog signaling pathway. Phase II study is to assess preliminary efficacy in both adult and pediatric patients with recurrent or refractory MB.
This phase I trial studies the side effects and best dose of gamma-secretase/Notch signalling pathway inhibitor RO4929097 (RO4929097) when given together with temozolomide and radiation therapy in treating patients with newly diagnosed malignant glioma. Enzyme inhibitors, such as gamma-secretase/Notch signalling pathway inhibitor RO4929097, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving gamma-secretase/Notch signalling pathway inhibitor RO4929097 together with temozolomide and radiation therapy may kill more tumor cells.
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.
TVI-Brain-1 is an experimental treatment that takes advantage of the fact that your body can produce immune cells, called 'killer' white blood cells that have the ability to kill large numbers of the cancer cells that are present in your body. TVI-Brain-1 is designed to generate large numbers of those 'killer' white blood cells and to deliver those cells into your body so that they can kill your cancer cells.
