View clinical trials related to Anaplastic Astrocytoma.
Filter by: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 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). The investigators have shown in a previous phase I trial that a single Superselective Intraarterial Cerebral Infusion (SIACI) of Bevacizumab (up to 15mg/kg) is safe and effective in the treatment of recurrent GBM. Therefore, this phase I/II clinical research trial is an extension of that trial in that the investigators seek to test the hypothesis that repeated dosing of intra-arterial Bevacizumab is safe and effective in the treatment of recurrent malignant glioma. Additionally the investigators will analyze if a combination with IA Carboplatin will further improve the treatment response. By achieving the aims of this study the investigators will also determine if IV therapy with Bevacizumab with IV Carboplatin should be combined with repeated selected intra-arterial Bevacizumab plus Carboplatin to improve progression free and overall survival. The investigators expect that this project will provide important information regarding the utility of repeated SIACI Bevacizumab therapy for malignant glioma, and may alter the way these drugs are delivered to the investigators patients in the near future.
BIBF 1120 is a newly discovered compound that may stop cancer cells from growing abnormally. This drug is currently being used in treatment for other cancers in research studies and information from those other research studies suggests that this agent, BIBF 1120, may help to stop recurrent malignant glioma cells from multiplying and it may also prevent the growth of new blood vessels at the site of the tumor. In this research study, the investigators are looking to see how well BIBF 1120 works in patients with recurrent malignant gliomas.
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....
Background: - The blood-brain barrier helps to protect the central nervous system (brain and spinal cord) from harmful toxins, but also prevents potentially useful chemotherapy from reaching brain tumors. The barrier is formed by tight connections between blood vessel cells and molecules found on the surface of brain blood vessels such as Permeability-glycoprotein (Pgp). Pgp may influence whether patients with brain tumors known as gliomas respond to chemotherapy and what side effects they may experience. The compound (11C)N-desmethyl-loperamide ((11C)dLop) reacts to Pgp molecules, and therefore may be used with positron emission tomography (PET) imaging to study the blood brain barrier. Objectives: - To study the ability of PET imaging with (11C)dLop to evaluate the blood brain barrier in brain tumor patients. Eligibility: - Individuals at least 18 years of age who have a brain tumor with characteristics that may be imaged with techniques such as magnetic resonance imaging (MRI) andPET. Design: - Participants will be screened with a full physical examination and medical history, blood and urine tests, and tumor imaging studies (fluorodeoxyglucose PET and MRI scans with contrast agent). - The (11C)dLop scan will take 1 hour to perform. Participants will be asked to return for blood and urine tests approximately 24 hours after the PET scan. - Participants will have followup visits at least every 4 months by repeating a complete history and physical exam and brain MRI. Participants may have repeat scans with (11C)dLop at various points in the course of cancer treatment, but will not have these scans more than twice in a 12-month period. - Participants will be followed for as long as possible during treatment to see if imaging with (11C)dLop correlates with response to the treatments.

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.

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 will determine the efficacy of the small molecule CDK4/6 inhibitor PD 0332991 (as measured by progression free survival at 6 months) in patients with recurrent glioblastoma multiforme or gliosarcoma who are Rb positive. A total of 30 patients will be treated; 15 will undergo a planned surgical resection and receive drug for 7 days prior to surgery, followed by drug after recovery from surgery, and the other 15 patients will receive drug without a planned surgical procedure.
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.
The main purpose of this study is to evaluate the most effective immunotherapy vaccine components in patients with malignant glioma. Teh investigators previous phase I study (IRB #03-04-053) already confirmed that this vaccine procedure is safe in patients with malignant brain tumors, and with an indication of extended survival in several patients. However, the previous trial design did not allow us to test which formulation of the vaccine was the most effective. This phase II study will attempt to dissect out which components are most effective together. Dendritic cells (DC) (cells which "present" or "show" cell identifiers to the immune system) isolated from the subject's own blood will be treated with tumor-cell lysate isolated from tumor tissue taken from the same subject during surgery. This pulsing (combining) of antigen-presenting and tumor lysate will be done to try to stimulate the immune system to recognize and destroy the patient's intracranial brain tumor. These pulsed DCs will then be injected back into the patient intradermally as a vaccine. The investigators will also utilize adjuvant imiquimod or poly ICLC (interstitial Cajal-like cell) in some treatment cohorts. It is thought that the host immune system might be taught to "recognize" the malignant brain tumor cells as "foreign" to the body by effectively presenting unique tumor antigens to the host immune cells (T-cells) in vivo.
