Active clinical trials for "Glioblastoma"

The purpose of this study is to determine the safety and utility of 5-aminolevulinic acid (ALA) for identifying your tumor during surgery. 5-ALA is not FDA approved at this time. When the investigators remove the tumor from your brain, it is important that they remove all of the tumor and not remove parts of normal brain. Sometimes this can be difficult because the tumor can look like normal brain. In some brain tumors, 5-ALA can make the tumors glow red under blue light. This may make it easier for your doctor to take out all of the tumor from your brain. The purpose of this study is to: Make sure that 5-ALA helps the doctor remove more of the tumor. Make sure 5-ALA does not cause any side effects. If you do not want to participate in this study, your doctor(s) will still do their best to remove all of the tumor in your brain. Whether or not you join this study will not change your treatment for your brain tumor.

On regular (diagnostic) MRI images brain tumors can show "contrast enhancement": uptake of an intravenously administered contrast agent can cause an enhancement pattern that is seen as a white area on a frequently used MRI protocol ("T1 weighted imaging"). High grade gliomas are a common brain tumor that share this enhancement pattern. The goal of surgery is to resect this contrast enhancing part without causing additional neurological damage. Intraoperative MRI (iMRI) is a helpful tool in achieving this goal, because it can provide updated images during resection and correct for deformations that occur in the brain during surgery. These deformations make preoperative images that are used for standard neuronavigation systems less reliable. However, due to manipulations during surgery, the contrast uptake during surgery may differ from contrast uptake in diagnostic MRI. This study aims to relate contrast enhancement on iMRI and tumor characteristics on tissue samples from the tumor. When the neurosurgeon considers the resection of the high grade glioma to be complete, an iMRI scan will be made, and tissue sampling will be performed on the borderzones of the tumor or tumor resection cavity respectively. This will provide insight in the relation between contrast enhancement on iMRI and the presence of tumor tissue. Such knowledge is important to improve effectiveness and safety of iMRI guided brain tumor resection.

This phase II trial is studying how well positron emission tomography (PET) scan using 18F-fluoromisonidazole works when given together with magnetic resonance imaging (MRI) ) in assessing tumor hypoxia in patients with newly diagnosed glioblastoma multiforme (GBM). Diagnostic procedures, such as MRI and PET scan using 18F-fluoromisonidazole (FMISO), may help predict the response of the tumor to the treatment and allow doctors to plan better treatment.

This is a safety study of tandutinib in combination with temozolomide and bevacizumab after people have received radiation therapy and temozolomide treatment. This study will determine the maximum safe dose of tandutinib when combined with temozolomide and bevacizumab and evaluate the safety of the combination treatment.

A Phase II, multi-center, open-label, single-arm study in up to 42 subjects with first recurrence or progression of GBM at up to 12 sites in Australia, Europe, Israel, and the United States. Subjects will receive intratumoral infusion of PRX321 administered via convection-enhanced delivery (CED) at a concentration of 1.5 μg/mL and a total volume of 60 mL over 2 to 7 days. Primary Objective: To evaluate the efficacy (expressed as overall survival at 6 months [OS-6]) of intratumoral infusion of PRX321 in subjects with first recurrence or progression of glioblastoma multiforme (GBM). Secondary Objectives: To assess the safety of intratumoral infusion with PRX321 in subjects with recurrent or progressive GBM. To evaluate objective response rate (ORR), duration of response (DR), overall survival (OS), and progression-free survival (PFS). Tertiary Objective: To evaluate the relationship of observed infusate distribution with clinical and radiological responses.

This is a study to see whether radiotherapy plus chemotherapy (Temozolomide) plus Dichloroacetate (DCA) improves overall survival and offers better control of the disease in patients with newly diagnosed Glioblastoma Multiforme Tumours.

Does treatment with bevacizumab (Avastin) in combination with prior or current radiotherapy lead to optic neuropathy?

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of temozolomide plus carboplatin in treating patients who have recurrent glioblastoma multiforme.

Romiplostim for low platelets caused by lomustine chemotherapy in patients with first recurrence (growing back) of a brain tumor, glioblastoma that is MGMT methylated. Lomustine is an anticancer drug often used to treat glioblastoma that grows back after initial treatment. This anticancer drug can cause side effects. The most frequent and potentially serious side effect of all is lowering of the blood platelets. Low platelets can cause bleedings in the the stomach and intestines, the skin, the brain and other systems and tissues. Low platelets are also the main cause of delaying or prematurely (ending treatment before the planned end) stopping chemotherapy. There is no treatment for low platelets except platelet transfusions. Romiplostim is a drug that stimulates the production of platelets in the bone marrow. It is an approved drug in USA, Europe, Australia and Switzerland for a special type of blood disease in which the body breaks down its own blood platelets. The purpose of the study is to start the treatment with romiplostim once low platelets are diagnosed in order to restore the platelet count and to prevent the platelet count from dropping again during the lomustine treatment.

This clinical trial increases radiation to areas of the brain considered to be at risk for cancer. The at-risk areas are identified by a biological MRI scan. The study will look at side effects of the radiation and overall survival.
