NCT01711580
Patients with a high grade glioma have an increasing overall survival and progression free survival after initial treatment. Because of a better performance status these patients are more often eligible for re-treatment with for example radiotherapy. However, to date only a few prospective studies on re-irradiation of gliomas exist and very little is known about the effects of re-irradiation on quality of life and cognition. This trial is designed to longitudinally establish the effects of re-irradiation on quality of life, cognition and physical performance in patients with a high grade glioma. Based on the currently available information the investigators hypothesize that quality of life after re-irradiation can be kept stable until further tumour progression.
NCT00427440
The purpose of this study is to evaluate the effectiveness and safety of AMG 102 for the treatment of Advanced Malignant Glioma.
NCT01351337
Resection of brain tumors in eloquent areas involves the risk of postoperative motor deficits. For brain tumors within or adjacent to the eloquent area, maximizing tumor resection while preserving motor function is crucially important.we used DTI-based tractography to visualize the spatial relationship between brain lesions and the nearby pyramidal tract(PT) in patients with malignant brain tumors and confirmed functional connections of the illustrated PT by direct electrical stimulation. We evaluated the reliability of DTI-based tractography for PT mapping using intraoperative subcortical stimulation ) and the usefulness of the combination of two techniques.
NCT00979862
This phase I trial is studying the side effects and best dose of cediranib maleate when given together with cilengitide in treating patients with progressive or recurrent glioblastoma. Cediranib maleate and cilengitide may stop the growth of tumor cells by blocking blood flow to the tumor. Giving cediranib maleate together with cilengitide may kill more tumor cells.
NCT01604590
This study is for subjects with a diagnosis of a brain tumor called glioblastoma that is being treated with bevacizumab. This study will use a new MRI technique to compare the images of blood vessels and tumor structure to the effectiveness of bevacizumab.
NCT01009866
Purpose of the study: Primary Objective: Determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of MR1-1KDEL when delivered intracerebrally by convection-enhanced delivery (CED) in patients with supratentorial malignant brain tumors. Secondary Objective: Document any radiographic responses associated with intracerebral CED of MR1-1KDEL. Hypothesis: The investigators believe that MR1-1KDEL will be an effective anti-tumor agent for patients with supratentorial malignant brain tumors when delivered by CED. Design \& procedures: This protocol is designed primarily to determine the MTD and DLT of a novel, tumor-specific immunotoxin, MR1-1KDEL. MR1-1KDEL will be delivered intracerebrally by CED using 2 intracerebral catheters with at least one catheter placed within the enhancing portion of the tumor. 124I-labeled albumin will be co-infused with gadolinium and PET and MRI images will be obtained at the conclusion of the infusion to monitor volume of drug distribution and leakage into the CSF space. Based on preclinical toxicity studies, the starting total drug dose will be 0.5μg (500ng) which represents 1/20th of the MTD in rats. The infusion flow rate will be fixed at 0.5 mL/h from each of two to four catheters. A total of 144 mLs of drug solution will be delivered over 72 hours. MR1-1KDEL dose escalation will be accomplished by increasing drug concentration allowing flow rate and infusion volume to remain unchanged. Drug dose will be doubled in successive cohorts so long as DLTs are not observed as follows: 25 ng/mL (2.4 μg)(starting dose); 50ng/mL (4.8μg); 100 ng/mL (9.6μg); 200ng/mL (19.2μg); 400 ng/mL (38.4μg); 800 ng/mL (76.8μg); and 1600 ng/mL (153.6μg). At least 3 patients will be enrolled in each cohort. All patients in a given cohort will be observed for at least two weeks following infusion of the study drug before patients in the next cohort are treated. If no patients in a given cohort experience a DLT, the dose will be escalated in the next cohort. If 1 out of 3 patients in a given cohort experience DLT, 3 additional patients will be entered in that cohort. If 2 patients develop a DLT in any cohort of 3 or 6 patients, the previous dose will be declared the MTD. Patients will be followed at 1, 3, 6, 9, 12 month intervals for toxicity and adverse events, radiographic response, and survival. Patients will be off study when progressive disease is documented. Risk/benefit assessment: This is an experimental study and unforeseeable or unexpected risks may be involved.
NCT01225510
Angiopoietin-2 (Ang-2) is a protein in the body which destabilizes blood vessels and is important in stimulating tumor blood vessels. There is evidence suggesting that Ang-2 may be important for the growth and progression of Glioblastoma multiforme (GBM). PF- 04856884 (CVX-060) is a compound which binds Ang-2 and prevents its activity. The hypothesis is that PF-04856884 will be safe and effective in patients with recurrent Glioblastoma multiforme (GBM).
NCT02227901
This phase I trial studies the side effects and best dose of tipifarnib when given together with radiation therapy and temozolomide in treating patients with newly diagnosed glioblastoma multiforme. Tipifarnib 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. 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. Giving tipifarnib together with radiation therapy and temozolomide may be a better way to treat glioblastoma multiforme.
NCT01131234
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.
NCT01115491
This is a Phase II, national, multicenter, open-label, non-comparative study to investigate the efficacy and safety of bevacizumab and temozolomide in patients with recurrent glioblastoma multiforme (GBM) after a first treatment failure. Patients will receive bevacizumab 10 mg/kg intravenously every two weeks until disease progression, consent withdrawal, or unacceptable toxicity. Anticipated time on study treatment is 12-24 months.
NCT02113358
Fluid management during neurosurgery presents a special clinical agenda. Volume overload can have detrimental effects on intracranial pressure by increasing either cerebral blood volume or hydrostatically driven cerebral edema formation. On the other hand, an overt restrictive fluid strategy may risk hemodynamic instability. Recently, dynamic fluid responsiveness parameters such as stroke volume variation (SVV) have been shown as a more precise parameters for fluid management including in neurosurgical patients. The threshold of SVV is reported about 10-15%. In this study, the investigators aim to using two SVV threshold to conduct intraoperative fluid therapy for craniotomy. Randomization will be generated by computer sampling. One of the two groups of patients will be managed with fluid bolus to keep intraoperative SVV \<10% presenting the "normovolemia" group. The other group of patients will be kept intraoperative SVV \<18% which is slightly above previously reported SVV threshold upper limit. The second group thus presents the "restrictive" group. Clinical outcomes, laboratory analysis including S100-B for neuronal damage and neutrophil gelatinase-associated lipocalin (NGAL) for acute kidney injury, will be compared.
NCT00378235
IL13-PE38QQR is an oncology drug product consisting of IL13 (interleukin-13) and PE38QQR (a bacteria toxin). IL3-PE38QQR is a protein that exhibits cell killing activity against a variety of IL13-receptor positive tumor cell lines indicating that it may show a therapeutic benefit. In reciprocal competition experiments, the interaction between IL13-PE38QQR and the IL13 receptors was shown to be highly specific for human glioma cells.
NCT00689221
CENTRIC is a Phase 3 clinical trial assessing efficacy and safety of the investigational integrin inhibitor, cilengitide, in combination with standard treatment versus standard treatment alone in newly diagnosed glioblastoma subjects with a methylated O6-methylguanine-deoxyribonucleic acid methyltransferase (MGMT) gene promoter in the tumor tissue. The MGMT gene promoter is a section of deoxyribonucleic acid (DNA) that acts as a controlling element in the expression of MGMT. Methylation of the MGMT gene promoter has been found to be a predictive marker for benefit from temozolomide (TMZ) treatment.
NCT00540176
Malignant gliomas, which include Glioblastoma multiforme (GBM), are the most common and most aggressive types of brain cancer, accounting for approximately 60% of primary brain tumors. These tumors are characterized by diverse molecular abnormalities (within the same tumor), which, along with the difficulties of many standard chemotherapies crossing the blood barrier, contribute to the very poor response to therapy and poor survival. We recently showed that Dichloroacetate (DCA, an inhibitor of the mitochondrial pyruvate dehydrogenase kinase) was able to depolarize cancer (but not normal) mitochondria and induce apoptosis in cancer but not normal tissues. We believe that altering the metabolism of cancers like glioblastoma (DCA switches metabolism from the cytoplasmic glycolysis to the mitochondrial glucose oxidation) we inhibit the resistance to apoptosis that characterizes cancer. Because metabolism (i.e. glycolysis) is the end result of many and diverse molecular pathways, the effects of DCA might be positive in cancers with diverse molecular backgrounds. DCA is also a very small molecule that readily crosses the blood brain barrier. Therefore we hypothesize that DCA will be an effective and relative non-toxic potential therapy for malignant gliomas. We are conducting a phase II trial with 2 parallel arms: a) patients with newly diagnosed malignant gliomas and b) patients with recurrent gliomas or gliomas that have failed standard therapy (which includes surgery, radiotherapy and chemotherapy). All patients need to have a histological diagnosis. DCA will be given orally and patients will be followed for a minimum of 6 months. The tumor size will be followed by standard MRI or CT criteria and glucose uptake (a direct effect of DCA on the tumor) will be measured by FDG-PET imaging. Several clinical parameters and quality of life will be followed. Potential toxicity (particularly peripheral neuropathy) will be closely followed and dose-de-escalation protocols are in place in case of toxicity. In addition, escape protocols for the application of standard therapy (when appropriate) are in place in patients with no evidence of response to DCA. In vitro studies will be performed in the tissues obtained at the time of surgery (where appropriate) and correlated prospectively with clinical data. There is limited ability to accept patients outside of Alberta; this is in part because the visit and testing schedule is intense, requiring residence in Edmonton for at least 6 months.
NCT00941460
For patients with progressive or recurrent glioblastoma there is no standard therapy. One strategy is re-exposure to temozolomide in a higher dose. This increase in dosing can be done by 2 regimens. Aim of this study is to compare these 2 dosing regimens concerning toxicity. In study arm A patients receive temozolomide for one week, followed by a week without temozolomide. In study arm B patients receive temozolomide for three weeks, followed by a week without temozolomide. The regimen that is less toxic will be selected for further evaluations.
NCT00539344
This is a phase 1, multi-centre, sequential cohort, open-label, dose-escalation study of the safety, tolerability, and PK of ANG1005 in patients with recurrent or progressive malignant glioma. ANG1005 will be given by IV infusion once every 21 days (1 treatment cycle). Each patient will participate in only 1 dose group and will receive up to 6 cycles of treatment provided there is no evidence of tumor progression, there is recovery to ≤Grade 1 or baseline nonhematologic, ANG1005-related toxicity (except alopecia), the absolute neutrophil count is ≥1.5 x 109/L, and the platelet count is ≥100 x 109/L.
NCT00003625
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining more than one chemotherapy drug with radiation therapy may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy plus radiation therapy in treating patients with newly diagnosed brain stem glioma.
NCT00362921
RATIONALE: Drugs used in chemotherapy, such as Gliadel wafer and O6-benzylguanine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving Gliadel wafer together with O6-benzylguanine works in treating patients with recurrent glioblastoma multiforme.
NCT00093613
This phase I trial is studying the side effects and best dose of sorafenib in treating patients with recurrent or progressive malignant glioma. Sorafenib may stop the growth of tumor cells by stopping blood flow to the tumor and by blocking the enzymes necessary for their growth.
NCT00095940
This phase I/II trial studies lapatinib to see how well it works in treating young patients with recurrent or refractory central nervous system (CNS) tumors. Lapatinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth.
