Active clinical trials for "Glioma"

Excision to the maximum possible extent marks the first step of glioma surgery. Depending on tumour histology, adjuvant treatment consists of radio- and/or chemotherapy. Multi-centre studies have shown that the presence of residual tumour according to MRI-criteria is a prognostic factor in this incurable condition. In order to improve the extent of resection, several methods, in particular intraoperative imaging techniques, have become available to demonstrate already during surgery whether the goal of surgery has been achieved. The intraoperative MRI devices currently available differ in their magnetic field strengths and image resolution, but also in their amount of interference with the surgical workflow. Prospective, high-class evidence data to promote the use of intraoperative MRI in glioma surgery are lacking. To assess whether the rate of radiologically complete tumour resections can be improved by using intraoperative MRI-guidance, we designed this prospective, randomized trial. We hypothesized that the extent of resection that can be achieved using an intraoperative MRI is greater than that of conventional microsurgical tumor resection.

Objectives: To define role of O6-Benzylguanine (BG) in restoring Temodar (temozolomide) sensitivity in patients with Temodar-resistant malignant glioma. To further define toxicity of combo therapy using Temodar + BG.

This study protocol examines a comparison between local and general anesthesia (Awake vs. Asleep Craniotomy) in the removal of brain tumors that are in areas of the brain that do not directly control bodily functions (non-eloquent gliomas).

Functional magnetic resonance imaging (fMRI) is a non-invasive test used to detect changes in brain activity by taking picture of changes in blood flow. The imaging helps doctors better understand how the brain works. Task based fMRI (TB fMRI) prompts patients to perform different activities (e.g. word selection in a reading task), and is routinely performed on patients in preparation for a Neurological surgery (surgery that involves the nervous system, brain and/or spinal cord). The purpose is to locate areas of the brain that control speech and movement; these images will help make decisions about patient surgeries. However, there are however gaps in knowledge specific to the language areas of the brain, especially for non-English patients and bilingual patients (those who are fluent in more than one language). This study proposes to evaluate if resting state fMRI (RS fMRI) that does not require any tasks, along with a novel way to analyze these images using "graphy theory," may provide more information. Graph theory is a new mathematical method to analyze the fMRI data. The overall goal is to determine if graph theory analysis on RS fMRI may reduce differences in health care treatment and outcomes for non-English speaking and bilingual patients. We hope that the results of this study will allow doctors to perform pre-operative fMRI in patients who do not speak English.

Phase I trial of CC-8490 for the treatment of subjects with recurrent/refractory high-grade gliomas

This phase I, open-label, dose-escalation study was conducted to determine the maximum tolerated dose (MTD), recommended phase II dose (RP2D), dose-limiting toxicities (DLTs), pharmacokinetics (PK) profile, and preliminary antitumor activity of single and multiple doses of PLB1001 in Patients with PTPRZ1-MET fusion gene positive recurrent high-grade Gliomas.

The purpose of this study is to determine the toxicity and tolerance of Myocet® in children and adolescents with refractory or relapsed malignant glioma, with a dose diminished of 20% of the dose recommended for adults and a dose recommended for adults, administered in single dose in 1-hour perfusion each 21 days. Other purposes are to determine the recommended dose of Myocet and to assess the response to drug. Pharmacokinetics of doxorubicin (free and encapsulated forms) and its metabolite doxorubicinol during 72 hours after Myocet administration will also be studied.

Objectives: To determine maximum tolerated dose of CPT-11 when administered following Temodar plus O6-benzylguanine To characterize any toxicity associated w combo of CPT-11 + Temodar plus O6-BG To observe pts for clinical antitumor response when treated w combo of CPT-11 + Temodar + O6-BG

Malignant gliomas are very aggressive and among the most common of brain tumors. A diagnosis carries with it a median survival of approximately 12 months, with 90 - 95% of patients surviving less than 2 years. The current standard treatment of surgical resection followed by radiation therapy and chemotherapy has not substantially prolonged survival and even the few treatment options shown to exhibit small increases in survival primarily benefit certain (i.e., young) patient subpopulations. Cancer vaccines represent one novel therapy for malignant gliomas. The goal is for the body to recognize the tumor cells as foreign and produce its own response to fight off recurring tumor cells. A promising means of causing an immune response so the body can create this immunity is through the use of dendritic cell (DC) vaccines. Dendritic cells are a small group of cells contained in everyone's white blood cell population. These cells are responsible for letting the immune system know that something foreign, like bacteria, or a tumor, is in the body. Dendritic cells help the body ward off disease by alerting the immune system. gliadel is an FDA - approved drug - a wafer containing a concentrated amount of a chemotherapy agent. These wafers are placed into the brain cavity after the tumor is resected (removed) and deliver a steady amount of immediate chemotherapy medicine to the surrounding brain tissue. Also, since Gliadel is a local chemotherapy, it will prevent the detrimental suppression (weakening) of the immune system shown with systemic (throughout the body) chemotherapy. In prior Phase l and phase ll studies, patients who received chemotherapy following Dendritic cells demonstrated longer progression free and overall survival than the patients who received Dendritic cells or chemotherapy alone. The purpose of this study is to determine whether after standard therapy of tumor resection surgery, along with placement of Gliadel wafers at time of surgery followed by dendritic cell vaccines will not only generate (start) an immune response, but will provide longer progression free survival. Patients who were screened and not enrolled in this clinical trial due to screen failure will be notified of the reason for screen failure. Pre HIV counseling and appropriate referral resources will be provided. If the screen failure is due to the positive HIV test, appropriate post HIV counseling will be provided and appropriate referrals will be made. The charts of the patients with screen failures will be destroyed.The patients charts who will be enrolled in the study kept in the locked cabinet in the research office. patients will be assigned a unique identifying code known only to the research team. Data will be captured by various source documents, or, as necessary, abstracted from hospital medical records by an experienced registered nurse. The electronic data for viral testing will be accessible to research personnel only.

OBJECTIVES: I. Assess the clinical response of patients with refractory or recurrent brain neoplasms treated with carmustine, streptozocin, and mercaptopurine.
