Filter by:Background: - AZD8055 is an experimental cancer treatment drug that works by inhibiting a protein called mTOR, which is known to promote tumor cell and blood vessel growth and to control tumor s energy and nutrient levels. AZD8055 is the first drug that inhibits both types of mTOR protein and is expected to be more effective than prior mTOR inhibitors. However, more research is needed to determine its safety and effectiveness in treating brain tumors known as gliomas that have not responded to standard treatments. Objectives: - To evaluate the safety and effectiveness of AZD8055 in individuals with gliomas that have not responded to standard treatments. Eligibility: - Individuals at least 18 years of age who have been diagnosed with gliomas that have not responded to standard chemotherapy, surgery, or radiation. Design: - Participants will be screened with a physical examination, medical history, blood tests, and tumor imaging studies. - Participants will be separated into two treatment groups: one group that will receive surgery to remove the glioma and one that will not have surgical treatment. - Participants in the nonsurgical treatment group will take AZD8055 by mouth daily for a 42-day cycle of treatment. Participants will keep a diary to record doses and keep track of any side effects. - Participants in the surgical treatment group will take AZD8055 by mouth daily for 7 days, and then will have tumor removal surgery. At least 3 weeks after surgery, participants will resume doses of AZD8055 and will continue to take the drug for as long as the tumor does not recur. - During treatment, participants will have regular visits to the clinical center, involving frequent blood and urine tests and other examinations to monitor the effects of treatment. Participants will have imaging studies to study the cancer's response to the treatment. - Participants will continue to have cycles of treatment for as long as the treatment continues to be effective and the side effects are not severe enough to stop participation in the study....
This phase I trial studies the side effects of vaccine therapy when given together with sargramostim in treating patients with malignant glioma. Vaccines made from survivin peptide may help the body build an effective immune response to kill tumor cells. Colony-stimulating factors, such as sargramostim, may increase the number of white blood cells and platelets found in bone marrow or peripheral blood. Giving vaccine therapy and sargramostim may be a better treatment for malignant glioma.
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.
Background: - Children who are diagnosed with brain tumors known as high grade gliomas or diffuse intrinsic pontine gliomas are generally treated with radiation therapy and chemotherapy. However, these tumors are very difficult to cure, and the tumor frequently begins to grow again even after treatment or surgery. Researchers are interested in determining whether the anticancer drug lenalidomide, which has been used to treat other aggressive types of cancer, is a safe and effective additional treatment for children who are scheduled to receive radiation therapy to treat high grade gliomas or diffuse intrinsic pontine gliomas. Objectives: - To determine the safety and effectiveness of lenalidomide, in conjunction with radiation therapy, as a treatment for children who have been diagnosed with high grade gliomas or diffuse intrinsic pontine gliomas. Eligibility: - Children and adolescents up to 21 years of age who have been diagnosed with high grade gliomas or diffuse intrinsic pontine gliomas and have not had radiotherapy or chemotherapy. Design: - Participants will be screened with a medical history, physical examination, blood and urine tests, and imaging studies. - Participants will have two phases of treatment: a lenalidomide plus radiation phase and a lenalidomide-only phase. - During the radiation phase, participants will take lenalidomide daily and have 6 weeks of radiation therapy (five treatments per week). After the radiation therapy, participants will stop taking lenalidomide for 2 weeks before continuing to the next phase. - During the lenalidomide-only phase, participants will take lenalidomide daily for 21 days, followed by 7 days without lenalidomide (28-day cycle of treatment). Participants will have up to 24 cycles of lenalidomide. - Participants will have frequent blood tests during the first cycle of treatment, and will have imaging studies or other tests as required by the study researchers. - Treatment will continue until the disease progresses, the participant chooses to leave the study, or the researchers end the study.
This phase I/II trial studies the side effects and best dose of vorinostat and to see how well it works when given together with radiation therapy followed by maintenance therapy with vorinostat in treating younger patients with newly diagnosed diffuse intrinsic pontine glioma (a brainstem tumor). Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving vorinostat together with radiation therapy may kill more tumor cells.
The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival durations of only 9-12 months for GBM, and 3-4 years for AA. Initial therapy has consisted of surgical resection, external beam radiation or both. More recently, a Phase 3 clinical published by Stupp et al in 2005 showed a benefit for using radiotherapy plus concomitant and adjuvant Temozolomide. Still, 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 Intra-arterial 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 Temozolomide (Temodar) has been shown to be active in human brain tumors but its actual central nervous system (CNS) penetration is unknown. This phase I clinical research trial will test the hypothesis that following the standard 42 day Temozolomide/radiotherapy regimen, Temozolomide can be safely used by direct intracranial superselective intra-arterial cerebral infusion (SIACI) up to a dose of 250mg/m2, followed by the standard maintenance cycle of temozolomide to ultimately enhance survival of patients with newly diagnosed GBM/AA. The investigators will determine the toxicity profile and maximum tolerated dose (MTD) of SIACI Temozolomide. The investigators expect that this project will provide important information regarding the utility of SIACI Temozolomide therapy for malignant gliomas, and may alter the way these drugs are delivered to our patients in the near future.
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.
