Active clinical trials for "Glioma"

This study evaluates the safety of PVSRIPO treatment in combination with Atezolizumab in patients with WHO grade IV malignant glioma. All patients will receive a single PVSRIPO infusion followed by atezolizumab infusions every three weeks for up to two years.

Several investigations suggest neural stem cells located in the subventricular region play an active role in promoting or even initiating cortical malignant glioma growth. Although normal appearing on neuroimaging, surgical specimens taken from this region show it contains malignant glioma stem-like cells. Some retrospective analyses found patients who received radiation therapy to this region during standard of care treatments lived longer than patients who did not. The investigator's study hypothesizes (1) stereotactic radiosurgery of cancer stem-like cells in these regions will be well tolerated during standard of care therapy, (2) focused stereotactic radiosurgery will be more effective in destroying cancer stem cells than conventional radiation therapy, and (3) treatment will improve malignant glioma survival.

The primary purpose of this study is to determine the maximum tolerated dose (MTD) of MT-201-GBM (pp65CMV antigen monocytes) that will be administered to patients newly diagnosed with a type of brain tumor called glioblastoma (GBM) that has an unmethylated MGMT (O[6]-methylguanine-DNA methyltransferase) (MGMT) gene promoter.

MK-2206 is a newly discovered drug that may slow or stop cancer growth. This drug has been used in other research studies, and information from those other research studies suggests that MK-2206 may help to slow or stop the growth of malignant gliomas. In addition, MK-2206 has the capacity to cross the blood-brain barrier. The blood-brain barrier (BBB) is a separation of circulating blood and cerebrospinal fluid (CSF) in the central nervous system (CNS); and although it serves as a protective barrier, it can often interfere with potentially beneficial treatments reaching the brain successfully. Therefore, the investigators hope that because MK-2206 can successfully cross the blood-brain barrier, it will be more effective in patients. The purpose of this study is to see how well MK-2206 works in patients with malignant gliomas and will be conducted in two parts: Part 1 and Part 2. Part 1 of the study will investigate the effects of MK-2206 on Akt signaling in tumor tissue. Ten patients with recurrent GBM who require reoperation will receive a short pre-operative course of MK-2206. After recovery from surgery, patients will resume MK-2206 until disease progression or the development of unacceptable toxicities. Part 2 of this trial will be initiated only AFTER analysis of Part 1 data shows drug penetration into tumor tissue; if there is no significant drug penetration into the tumor and/or there is no reduction of pAkt levels, progression to Part 2 of the trial will be halted. The primary goal of Part 2 is to determine the therapeutic efficacy of MK-2206 as measured by 6-month progression-free survival (PFS6). In Part 2, 40 participants with GBM and 18 with anaplastic glioma will be treated with MK-2206 weekly at a dose selected on the basis of an ongoing phase 1 study. Treatment duration will be measured in 4-week cycles. Participants will remain on treatment until tumor progression, as long as there are no unacceptable toxicities. Responses will be assessed by clinical examinations every 4 weeks and MRI scans every 8 weeks.

The primary objective of this study is to determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of dasatinib when combined with protracted, daily temozolomide (TMZ). Secondary objectives are: To further evaluate the safety and tolerability of dasatinib plus protracted, daily TMZ; 2. To evaluate the pharmacokinetics of dasatinib when administered with protracted, daily TMZ among recurrent malignant glioma patients who are on and not on CYP-3A enzyme inducing anti-epileptic drugs (EIAEDs); 3. To evaluate for anti-tumor activity with this regimen in this patient population.

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.

A Pilot Study Evaluating Minimized Time to Beam Hypofractionated IMRT with PET Assisted Target Definition in Patients with High Grade Gliomas The aim of this pilot project is to explore the feasibility of combining a simple conformal plan (Phase I) with an IMRT treatment approach (Phase II) for high grade glioma patients with the aim of starting the RT as soon as possible following the patient's first outpatient visit (thus, minimized 'time to beam'). It is hoped that the rapid treatment start with the initial 3D CRT plan will lessen clinical deterioration due to the growth of these aggressive tumours. The use of Linac-based IMRT in Phase II of the patient's treatment plan will maintain the benefit of the sophistication of IMRT. Using novel PET imaging we also hope to better characterize regions of glioma cells thus producing more optimized planning target volumes (PTVs) for each patient and decreasing the volume of normal brain irradiated with the aim of minimizing radiation toxicities. Hopefully this planning and treatment approach will provide an improvement in the quality of life and outcome for high grade glioma patients.

RATIONALE: Immunotoxins can locate tumor cells and kill them without harming normal cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of immunotoxin therapy and to see how well it works in treating children undergoing surgery for recurrent or progressive malignant glioma.

The purpose of this research study is to learn if the study drug RAD001 can shrink or slow the growth of low-grade gliomas in children with Neurofibromatosis type 1 (NF1). Additionally, the safety of RAD001 will be studied. The study drug, RAD001, is a drug that may act directly on tumor cells by preventing tumor cell growth and development. RAD001 has been studied in participants with various types of cancer as a single agent (a drug that is used alone to treat the cancer) or in combination with a number of well known anticancer therapies. Information from these research studies suggests that RAD001 may help to shrink or slow the growth of low-grade gliomas. In this research study, the investigators are looking to see the response of RAD001 in children with low-grade gliomas and NF1 that have either not responded to treatment or have come back after treatment. We are also looking for the highest dose of RAD001 that can be given safely in this patient population.

The aim of the present Phase III study is to assess the positive predictive value of NPC-07 (5-aminolevulinic acid hydrochloride) induced tissue fluorescence, safety and pharmacokinetics following a single dose of NPC-07 orally, at a dose of 20mg/kg/body weight, 3 hours prior to induction of anaesthesia for surgery of patients with newly or recurrent malignant glioma (WHO grades III/IV). Positive predictive value will be confirmed by percentage of patients showing positive tumor cell identification in all biopsies taken from areas of strong and weak fluorescence. This study will be divided into two stages. After reviewing of the result of safety and pharmacokinetics of NPC-07 in small number of subjects by independent safety monitoring committee, more subjects will receive NPC-07 in Step II.
