Active clinical trials for "Glioma"

This study will evaluate the safety and tolerability of increasing doses of PF-06840003 in patients with malignant gliomas.

The purpose of this research study is to evaluate an investigational drug (Vismodegib) for Pontine Glioma that is growing or has come back (reoccurred). This study will look at the tumors response to the study drug, Vismodegib, and will also look at the safety and tolerability of Vismodegib. Vismodegib has been tested in multiple adult clinical trials and one pediatric trial. Laboratory testing in pontine gliomas suggests that this drug may be effective in treating this disease.

In this study subjects will be administered a single oral dose of Aminolevulinic Acid (ALA) prior to surgical resection of their brain tumor. The ALA ultimately causes brain tumor tissue to fluoresce or light up under ultraviolet light. During surgery an ultraviolet light in the microscope chain will be turned on. The tumor tissue will fluoresce bright pink allowing the surgeon to more easily differentiate tumor tissue from normal brain tissue. The aim of the study is to determine whether ALA and fluorescent visualization of tumor tissue improves the surgeon's ability to completely resect or remove the brain tumor.

The primary objectives of the study are to determine the maximum tolerated dose (MTD) of Carboxyamidotriazole Orotate (CTO) when combined with standard dosing of bevacizumab among patients with recurrent malignant glioma (WHO grade III or IV) that have previously failed bevacizumab (Phase 1); to determine the activity of CTO alone in bevacizumab-failure WHO grade IV malignant glioma patients (Phase 2, Arm 1); to determine the activity of CTO plus bevacizumab in bevacizumab-failure WHO grade IV malignant glioma patients (Phase 2, Arm 2). This study was terminated early due to funding issues. At the time of termination, the study was still in Phase 1 and no MTD for the combination of CTO and bevacizumab had been determined for this population. Phase 2 will not proceed.

The primary objective of this study is to evaluate the efficacy of a combined treatment with cilengitide and metronomic oral temozolomide as measured by 6 months overall survival (OS) after diagnosis of relapse or tumour progression in children and adolescents with relapsed or refractory high-grade malignant glioma and diffuse intrinsic pontine glioma. Secondary objectives include: To evaluate the safety and toxicity of the study treatment by common toxicity criteria (CTC; version 4.0). To assess the response rates at 6 months (continuous complete response = CCR, complete response = CR, partial response = PR, stable disease = SD, progressive disease = PD) and progression-free survival (PFS) at 6 months, and response rates, OS, and PFS at 12 months after relapse diagnosis or diagnosis of tumor progression. Response will be presented including histopathological variants. To assess the pharmacokinetics of cilengitide administered as part of the study treatment. Indication and study population for this trial: Treatment of relapsed or refractory high grade gliomas and diffuse intrinsic pontine gliomas in paediatric patients ≥ 3 years and < 18 years of age. Patients included in the study receive Cilengitide 1800 mg/m² i.v. twice weekly Temozolomide 75 mg/m²/d p.o. for 6 weeks, followed by 1 week rest with a mandatory platelet-count dependent dose adaptation rule: mandatory blood counts twice weekely: Platelets ≥ 100 000/µl (≥ 100 Gpt/l): 75 mg/m², platelets ≥ 50 000 - < 100 000/µl (≥ 50 - <100 Gpt/l): 50 mg/m², platelets < 50 000/µl (<50 Gpt/l): stop temozolomide until platelet recovery ≥ 100 000/µl (≥100 Gpt/l) Study treatment in the individual patient is scheduled for 1 year unless tumor progression or excessive toxicity occurs. However, study treatment may be extended beyond 1 year upon individual decision.

This phase I/II clinical trial is studying the side effects and best dose of gamma-secretase inhibitor RO4929097 and to see how well it works in treating young patients with relapsed or refractory solid tumors, CNS tumors, lymphoma, or T-cell leukemia. Gamma-secretase inhibitor RO4929097 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Background: Diffusely infiltrating pontine glioma (DIPG) or supratentorial high-grade glioma (HGG) are brain tumors that are often difficult to treat. It is very difficult to get chemotherapy agents to tumors in the brain, and researchers are looking for new methods to directly treat these types of cancer. IL-13 is an immune molecule normally occurring in the body. Patients with gliomas appear to have significant amounts of the IL-13 receptors in their brain tumors. An experimental drug, IL13-PE38QQR, combines a bacteria toxin with human IL-13 to allow the toxin to enter and destroy the tumor cell. Early clinical studies suggest this treatment may prolong survival of patients with these types of brain tumors. A technique called convection-enhanced delivery (CED) uses continuous pressure to push large molecules through the membranes protecting the brain to reach brain tumors. This technique can treat a tumor more directly than with traditional methods. Objectives: To test the safety and feasibility of giving IL13-PE38QQR directly into regions of the brain in pediatric patients with DIPG or HGG, using CED. To determine the most appropriate dose of IL13-PE38QQR to treat DIPG or HGG. To determine the effects of this experimental therapy on the tumor. To evaluate the physical changes in the tumor before and after the therapy. Eligibility: Patients who are less than 18 years of age and have been diagnosed with either DIPG or with supratentorial HGG that has not responded well to standard treatments. Design: Patients will be admitted to the hospital and will receive a magnetic resonance imaging (MRI) scan to show the exact location of the tumor. A small plastic tube will be inserted surgically into the tumor area, and IL13-PE38QQR and a MRI contrast agent (gadolinium DTPA) will be infused into the area. MRI scans will monitor the process, and the tube will be removed after surgery. Doses will be adjusted over the course of the study. Patients who respond well to treatment may be eligible to receive a second infusion, no sooner than 4 weeks after the first treatment. Post-treatment visits: Clinic visits 4 and 8 weeks after the treatment, and then every 8 weeks for up to 1 year. Physical examination with neurological testing, an MRI, and standard blood and urine tests.

RATIONALE: Drugs used in chemotherapy, such as temozolomide and VNP40101M, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Temozolomide may also stop the growth of tumor cells by blocking blood flow to the tumor. PURPOSE: This phase I/II trial is studying the side effects and best dose of VNP40101M when given together with temozolomide and to see how well it works in treating patients with progressive or relapsed malignant glioma.

This phase I trial is studying the side effects and best dose of aminolevulinic acid during surgery in treating patients with malignant brain tumors. Aminolevulinic acid becomes active when it is exposed to a certain kind of light and may help doctors find and remove tumor cells during surgery

This study will examine the safety of a twice-a-day dosing regimen of the experimental drug Enzastaurin in patients with malignant glioma (a cancerous brain tumor) who are and who are not taking certain anti-seizure medicines. Enzastaurin may prevent the formation of new blood vessels that tumors need to grow. It has shown some effect against brain tumors in animals and in some patients with recurrent gliomas. This study will see if the drug can help patients with gliomas and how much drug they should be given. Patients 18 years of age and older with malignant glioma that has recurred after standard therapy may be eligible for this study. Candidates are screened with a physical examination, blood and urine tests, magnetic resonance imaging (MRI) or computed tomography (CT) scans, and an electrocardiogram. Participants are divided into two groups of patients-those who are and those who are not taking certain anti-seizure medications-in order to determine if the anti-seizure medication alters the way the body handles Enzastaurin. Patients in both groups are further divided into different dosing regimens: some in each group take Enzastaurin once a day for 3 weeks, followed by twice a day for 3 weeks; others in the group take the drug twice a day for 3 weeks followed by once a day for 3 weeks. The medication is taken by mouth every day. Treatment is given in 6-week cycles and may continue for 1 year unless the tumor grows or the patient develops unacceptable drug side effects. In addition to drug treatment, patients have the following tests and procedures: Medical history, physical, and neurological examinations every 3 weeks during the first cycle and then every 6 weeks. MRI or CT scan of the head before starting each new cycle. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. CT uses x-rays to provide 3-dimensional views of the part of the body being studied. For both procedures, the patient lies on a table that slides into the cylindrical scanner. Routine blood tests every week during the first cycle and every 3 weeks after that. Electrocardiogram on days 21 and 42 of the first cycle, just before taking the drug and 30 minutes and 4 hours after taking the drug. Pharmacokinetic studies within 3 days of day 21 of the first cycle. Several blood samples are drawn to measure levels of Enzastaurin. Patients taking the drug once a day have blood samples drawn before the morning dose and 1, 2, 4, 6 and 24 hours after the dose. Patients taking the drug twice a day have samples drawn before the morning dose, at 1, 2, 4, 6 and 12 hours after the dose, and then 12 hours after the evening dose. In addition, on day 1 an extra tube of blood is drawn at the time of the Enzastaurin dose and 4 hours later. Dynamic MRI with spectroscopy or PET. These tests are done to help distinguish live tumor from dying tumor. The experience of dynamic MRI with spectroscopy is the same as standard MRI and is done at the same time as the standard procedure. PET uses a radioactive substance to show cellular activity in specific tissues of the body. The patient is given an injection of a sugar solution in which a radioactive isotope has been attached to the sugar molecule. A special camera detects the radiation emitted by the radioisotope, and the resulting images show how much glucose is being used in various parts of the body. Because rapidly growing cells, such as tumors, take up and use more glucose than normal cells do, this test can be used to show active tumors.
