Active clinical trials for "Glioblastoma"

Phase 1b of the study, will evaluate the safety and tolerability of AQ4N treatment at three different dose levels. Phase 2a of the study, will further evaluate the safety, tolerability, and in addition efficacy of AQ4N treatment at a tolerated dose selected from Phase 1b.

Prospective, open-labeled, multicenter cohort trial for validation of the role of levetiracetam as a sensitizer of temozolomide in the treatment of newly diagnosed glioblastoma patients.

The aim of this study was to analyse usefulness of [68Ga]Ga-PSMA-11 PET/CT scans in preoperative differentiation between HGG and LGG in patients with suspicion of a tumor of glial origin in previously performed imaging examinations. The PET/CT scan will be compared with postoperative histopathological results and with additional immunohistochemical staining for PSMA expression.

This clinical trial studies steady state blood volume maps using ferumoxytol non-stoichiometric magnetite magnetic resonance (MRI) in imaging patients with glioblastoma. MRI is a procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. Contrast agents, such as ferumoxytol non-stoichiometric magnetite, may enhance these pictures and increase visibility of tumor cells and the blood vessels in and around the tumors.

This study is being conducted to help determine whether the addition of Interferon-alpha(α-IFN),which were determined sensitized the activity of Temozolomide(TMZ) in vivo and vitro, when given along with temozolomide during the monthly cycles that follow radiation, is able to delay tumor growth, shrink tumors, or impact how long people with newly diagnosed high-grade glioma.

The purpose of this study is to evaluate diagnostic imaging techniques using 124I-NM404 PET/CT in human brain tumors. This goal will be accomplished by quantifying tumor uptake and determining the optimal PET/CT protocol, comparing PET tumor uptake to MRI, and calculating tumor dosimetry. The long-term goals of this research are to improve the diagnosis and treatment of malignant brain tumors by using radioiodinated NM404

This pilot clinical trial studies how a magnetic resonance imaging (MRI) study with ferumoxytol works as a contrasting agent in assessing early response in patients with glioblastoma multiforme receiving temozolomide and radiation therapy. Ferumoxytol is a very small form of iron particles that are injected into the body and taken up by certain tissues which may make these tissues easier to see during imaging. Diagnostic procedures, such as an MRI study with ferumoxytol, may help measure a patient's response to earlier treatment.

It was previously shown that 18F-DOPA PET imaging results in intended management changes in 41% of brain tumor patients. However, its impact on patient outcome defined as survival, costs, and/or quality of life has not been demonstrated. Regulatory agencies require randomized trials to determine the impact of PET on patient management and outcome. In this study we hypothesize that the addition of 18F-DOPA PET will improve patient outcome by more accurately identifying presence or absence of tumor recurrence than conventional imaging.

The purpose of the study is to conduct a pilot test of a new tracer in healthy human volunteers to define normal tracer biodistribution (where the tracer goes), stability (how much metabolises), pharmacokinetics (how much stays in which organs and for how long), and radiation dosimetry (organ radiation dose). The same radiopharmaceutical will then be tested in cancer patients.

18F-Fluorothymidine is a recently developed PET tracer to image tumor cell proliferation. Very few data report an interest of using such a tracer for cerebral malignant tumor management. In our project, we want to compare the tumoral volumes obtained with PET and MRI, with the gold standard histopathological diagnosis according to the WHO grading malignancy scale and the Ki-67 proliferation index, for preoperative evaluation as much as for tumoral postoperative residue evaluation. Furthermore, we want to explore the interest of 18F-FLT-PET volume to better delineate tumoral volume in radiotherapeutic management of gliomas.
