NCT00024557
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. Patients will receive IL13-PE38QQR via a catheter placed directly into the brain tumor. Tumor recurrence will be confirmed by biopsy. The next day, patients will start a continuous 48-hour infusion of IL13-PE38QQR into the tumor. The dose (concentration) will be increased in the pre-resection infusion until the endpoint is reached (histologic evidence of tumor cytotoxicity or a maximum tolerated dose). Tumor resection will be planned for one week after biopsy, plus or minus 1 day. A histologically-effective concentration (HEC) will be determined using pathologic observations. At the end of resection, three catheters will be placed in brain tissue next to the resection site and assessed within 24 hours using MRI. On the second day after surgery, IL13-PE38QQR infusion will begin and will continue for 4 days. The lowest pre-resection IL13-PE38QQR concentration will be used as the starting dose for post-resection infusions. After an HEC or maximum tolerated dose (MTD) is determined, the pre-resection infusion will no longer be administered. Subsequent patients will have tumor resection and placement of three peri-tumoral catheters at study entry. IL13-PE38QQR will be infused starting on the second day after surgery and continuing for 4 days. Escalation of the post-resection IL13-PE38QQR concentration will be continued until the previously-defined HEC or MTD is reached, after which duration of the post-resection infusion will be increased in one day increments for up to 6 days. If a post-resection MTD is obtained, there will be no increase in duration of infusion. In the final stage of the study, catheters will be placed 2 days after tumor resection, and a 4-day IL13-PE38QQR infusion will begin the day after catheter placement. Patients will be observed clinically and radiographically for toxicity and duration of tumor control.
NCT00062504
To analyze the effect of Talampanel on progression free survival in patients with recurrent high grade gliomas.
NCT00238797
The purpose of the study is to determine the efficacy of gefitinib (IressaTM) in combination with radiotherapy on patients with glioblastoma multiforme.
NCT00671710
Tumors of the central nervous system are potentially curable. For tumors of comparable histology and grade, resectability is the most important prognostic factor affecting survival particularly in children. However, the infiltrative nature of the malignant cells produces indistinct borders between normal and malignant tissues, and the lack of easily identifiable tumor margins confounds attempts toward total resection. The investigators propose to identify the borders of tumors intraoperatively using protoporphyrin fluorescence of the malignant cells and thereby provide more complete tumor resection.
NCT01242566
The management of glioblastoma in elderly patients with poor performance status (KPS\<70) is unsettled. This single arm phase 2 trial trial was designed to evaluate the efficacy and safety of temozolomide alone in this population
NCT01208909
In the treatment of glioblastoma (GBM) neurosurgical resection of the tumor is usually considered a a first step of effective therapy. Radical resection of the tumor is highly beneficial to the patient as measured in progression-free survival and overall survival. At the same time eloquent areas of the brain have to remain intact to preserve quality of life. Both 5-ALA fluorescence and intraoperative MRI are used for intraoperative marking of tumor tissue and thereby to improve precision of GBM-Resection. We now study whether the combination of 5-ALA fluorescence and intraoperative MRI increases the number of sites where tumor tissue can be detected. \- Trial with surgical intervention
NCT00535379
Clinical Part: The objective of this study is to determine the efficacy and safety of SUTENT in patients with recurrent or progressive glioblastoma multiforme.Patients with tissue based diagnosis of intracranial glioblastoma multiforme, above 18 years of age and of both genders, who have a first tumor recurrence or progress after surgery, radiation- and chemotherapy will be included. The hypothesis is that SUTENT will significantly increase the progression free survival rate at 6 months in the study population.
NCT00848523
The drug LBH589 (panobinostat) is an experimental (investigational) drug that is being tested for recurrent (returning) malignant gliomas. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). It belongs to a new class of drugs called "histone deacetylase inhibitors." Histones are proteins located in the nucleus of cells that bind to DNA, the chemical that makes up genes. These proteins help control which genes are turned "on" and "off." Studies have shown that drugs like panobinostat (LBH589) may lead to tumor cell death.
NCT00165477
\- The purpose of this study is to find out if the combination of lenalidomide and radiation therapy is effective in controlling tumor growth in patients with newly-diagnosed supratentorial glioblastoma or gliosarcoma.
NCT01083719
HYPOTHESIS AND SAMPLE SIZE The tumor delineated by FDG-PET is significantly different from the delineation achieved by MR T1 contrast weighted images in glioblastoma; expecting a standard error of 12.5 % (a confidence interval of 25%), with a confidence level set at 95%, a sample size of 15 patients would be accrued in the study.
NCT00909558
The purpose of this study is to assess the safety and effectiveness of natural killer (NK) cell and natural killer T (NKT) cell-based autologous adoptive immunotherapy in subjects with metastatic, treatment-refractory breast cancer, glioma, hepatocellular carcinoma, squamous cell lung cancer, pancreatic cancer, colon cancer or prostate cancer.
NCT00660621
To determine the safety and efficacy of surgical resection with Gliadel® 3.85% wafer implantation, followed by concomitant limited field radiation therapy and temozolomide, followed by dose dense temozolomide and bevacizumab in subjects undergoing initial surgery for newly-diagnosed high grade glioma.
NCT00283569
To establish a clinic based case control study for examination of potential risk factors for primary adult brain tumors.
NCT00392119
The purpose of this study is to determine if the stereotactic, MR guided, laser interstitial thermal therapy treatment technique can be safety and efficiently used for human brain metastasis and primary brain tumors.
NCT00224978
Chloroquine is a strong lysosomotropic and DNA-intercalating agent in experimental studies (Neurosurgical Focus 14(2): February, 2003) and an open-label clinical trial the investigators have demonstrated a strong adjuvant effect of chloroquine on the therapy of malignant gliomas. This study will assess in a randomized, placebo-controlled, double-blind study the effects of chloroquine as adjuvant to the conventional therapy of Glioblastoma Multiforme.
NCT00977327
Purpose: * Improvement of extent of resection by the use of intraoperatively acquired image data sets to navigate. * Better define the role of different intra-operative imaging modalities, used to update the navigational data set, in aiding the surgeon during resection of intra-axial brain lesions. * To examine the cost-effectiveness of different intraoperative navigational systems as a function of operative time and Operative time (Surgery including imaging) There is increasing neuro-oncological evidence that extent of resection might have an impact in particular in low-grade lesions.
NCT00180193
The purpose of this study is to monitor the amino acid uptake of brain tumors, before and during radiotherapy, with positron emission tomography.
NCT00944801
Glioblastomas represent 40% of all tumors of the central nervous system (CNS) and are among the most lethal tumors. Temozolomide (TMZ) combined with radiotherapy was the first substance to significantly improve the overall survival (to 14.6 months) as compared to surgery and radiotherapy alone and increased the proportion of patients surviving more than 2 years to 26%. TMZ showed the best efficacy in patients with a methylated O6-methylguanine-DNA methyltransferase (MGMT) promoter in part by eliminating stem cell-like tumor cells. Among patients with a methylated MGMT promoter, the median survival after treatment with combined radio-chemotherapy was 21.7 months, as compared to 15.3 months among those who were assigned to radiotherapy only. In the absence of methylation of the MGMT promoter, there was a smaller and statistically insignificant difference in survival between the treatment groups. Doxorubicin is one of the most effective substances in vitro against cells derived from glioblastoma. However, it has no significant effect in vivo due to poor blood-brain-barrier penetration. In a tumor model, tissue and CSF-concentrations of doxorubicin were substantially increased when sterically stabilized liposomes were used resulting in a comparable clinical response using approximately half of the dose of stabilized liposomes compared to conventional doxorubicin. A pegylated formulation (PEG-liposomal Doxorubicin) even further improved the penetration of the blood-brain barrier. Case series and two phase II-studies in patients with recurrent glioblastoma have shown modestly promising results for PEG-Dox. In this study, the investigators treated patients with recurrent glioblastoma with 20 mg/m2 PEG-Dox on days 1 and 15 of each 28-day cycle. To determine the dose limiting toxicity of PEG-Dox combined with prolonged administration of TMZ, the investigators performed a phase I part ahead of the phase II study. To investigate, by means of a historical control analysis, if the addition of PEG-Dox to TMZ and radiotherapy improves the survival of patients, the investigators chose similar inclusion criteria and identical TMZ and radiotherapeutic regimes as in the EORTC26981/NCIC-CE.3 study.
NCT00683761
The purpose of this study is to evaluate the safety and effectiveness of 131I-TM601 in the treatment of adult patients with progressive or recurrent malignant gliomas.
NCT00599703
The purpose of this study is to use an imaging method called functional magnetic resonance imaging (fMRI) in patients who have a tumor near an area of the brain that is believed to control language. The fMRI is a new kind of imaging that uses a strong magnetic field to look at functioning brain tissue. This kind of imaging will be used to study the effect of the brain tumor on your speech.
