Active clinical trials for "Glioblastoma"

A prospective, open-label, phase 2 study to explore CAIX expression through 89Zirconium-labelled girentuximab deferoxamine (89Zr-girentuximab) PET/CT imaging in patients with solid tumors.

The investigators are developing a novel standardized and centralized approach named Integrated Personalized Functional Profiling (PFP) in Luxembourg. Based on recent improvements in cancer biopsy-derived 3D-culture technologies the PFP process will screen patient derived cells (PDCs) with FDA/EMA-approved drugs to generate personalized functional response profiles. The selected drug through PFP technology will provide personalized treatment recommendation for the patient. This pilot study will evaluate the clinical feasibility of setting-up an effective workflow as a first step. Outcomes from this study will be used subsequently to help plan the clinical validation of the implementation of PFP.

An open-label, single institutional phase II trial of losartan in patients with primary and metastatic brain tumors with an individual stepped-wedge, randomized, assessor-blinded, dose-finding design on three indications.

The proposal is to conduct a prospective, multi-cohort study aiming to decipher molecular profiles/biological characteristics of advanced cancer patients during the course of their disease with longitudinal and sequential analyses of tumor and liquid biopsies. This approach will allow i) to develop a model in order to predict tumor response / resistance in real life conditions and to better understand adaptive mechanisms and ii) to potentially propose therapeutic options to enrolled patients following the review of the biological/molecular data generated during this study and during a Molecular Tumor Board in case of disease progression. This study will include 12 cohorts according to tumor type and standard treatment received (See Inclusion criteria I1). Patient will be enrolled before the initiation of standard anti-cancer treatment.

This research study is for Glioblastoma (GBM) patients who will be beginning Optune as part of their clinical care, which is a novel treatment that utilizes - tumor treating fields (TTFields), (aka, electrical therapy), which has shown to improve overall survival in large multi-center trials. As a part of this study, participants will either receive Optune with "standard array mapping" (based on regular contrast enhanced MRI) or an "alternative (more precise) array mapping" based on sophisticated state of the art MRI techniques including "whole brain spectroscopy". Whole brain MRI spectroscopy provides additional metabolic information to map out the full extent of tumor spreading within the brain (far beyond from what is seen on regular MRI), by identifying certain metabolites that are present in cancer cells versus healthy tissue. This study is being performed to show whether alternative array mapping improves treatment outcomes, as opposed to the standard array mapping, by maximizing delivery of TTFields dose, thereby achieving more effective tumor cell killing, decreasing the rate of local recurrence, and improving the overall survival as well as quality of life measures.

After surgery, a key step in treatment of patients diagnosed with glioblastoma (high grade brain tumour) is radiotherapy. The ideal clinical target volume (CTV) for radiotherapy treatment planning includes all tumour cells remaining after surgery. Currently, the GTV is delineated on conventional imaging techniques that are only visualizing macroscale structural changes due to the presence of a large number of tumour cells. After delineating these visible macroscale changes, the GTV is expanded in all directions with 1.5cm into visibly healthy tissue to account for microscale tumour invasion. This standard CTV therefore also contains healthy tissue that should not be receiving radiation, causing side effects of treatment, hereby reducing quality of life for patients. Generating a physiological CTV, in which microscale invasion of tumour cells is taken into account specifically whilst sparing healthy tissue that is not in need of radiation, is essential for reducing side effects of radiotherapy. To do so, visualisation is necessary of physiological processes of tumour cells, which are present before macroscale structural changes occur. State-of-the-art MRI techniques are now in use at the Erasmus MC that can assess these physiological processes, including oxygenation status and cell proliferation. We aim to generate proof-of-concept of using a physiological CTV for radiotherapy treatment planning for patients with brain tumours. By extending the clinical standard MRI session used for radiotherapy planning in 10 patients diagnosed with glioblastoma with advanced MRI techniques that assess oxygenation status and cell proliferation, we will generate the physiological CTV including this information and illustrate that it is more precise in capturing microscale tumour invasion. This proof-of-principle work will be used to obtain external funding to perform the much needed, and the first of its kind globally, clinical trial to show the benefit of a physiological CTV for radiotherapy treatment planning in glioblastoma.

This clinical trial uses a type of imaging scan called magnetic resonance imaging (MRI) to study brain tumor biology in patients with glioblastoma that can be removed by surgery (resectable). Malignant gliomas are the second leading cause of cancer mortality in people under the age of 35 in the United States. Glioblastoma is a type of malignant glioma with very poor patient prognosis. There are currently only about 3 drugs approved by the Food and Drug Administration (FDA) for the treatment of glioblastoma, one of them being administration of bevacizumab, which is very expensive. It is the most widely used treatment for glioblastoma with dramatic results. However, previous clinical trials have not demonstrated an overall survival benefit across all patient populations with glioblastoma that has returned after treatment (recurrent). The study aims to identify which patients who will benefit from bevacizumab therapy by observing MRI images and corresponding imaging biomarkers.

The primary objective of this study is to evaluate the diagnostic performance of the CONVIVO confocal endomicroscope in discriminating between normal and abnormal tissue in vivo during brain tumor surgery. The interpretation of intraoperative images obtained in situ will be tested against conventional histologic evaluation of targeted biopsies from imaged tissue. The study team hypothesize that there will be a high degree of correlation between images obtained with the CONVIVO system and conventional histologic interpretation.

MRI including ASL will be performed before, during and after the treatment, in a total of 7 MRI sessions until 8 months after the first session. Thereafter, patients will be followed through standard clinical examinations for the next 3 years or until demise, whichever occurs first. Clinically, GBM patients are imaged every 8-weeks, beginning at 10 weeks after the completion of chemoradiation, since morphological (i.e. size) changes are not anticipated earlier. However, our preliminary experience and others have shown functional changes including perfusion and diffusion as early as 3-weeks after the initiation of the treatment . Thus, our T10, T18, T26 and T34 MRI sessions will be performed along with the clinical imaging sessions, while the T3 and T6 MRI sessions will be performed additionally for this proposal. All MR imaging sessions will be scheduled within ±1 or ±2 weeks of the target time period, as indicated in the table. MRI including ASL will be performed before, during and after the treatment, in a total of 7 MRI sessions until 8 months after the first session. The research MR imaging may take approximately an additional 15 minutes per each imaging session. However, the T3, and T6 MR imaging sessions will be performed additionally for the purpose of this study, with each taking approximately one hour. Thereafter, patients will be followed through standard clinical examinations for the next 3 years or until demise, whichever occurs first.

This study aims to treat patients who have been diagnosed with brain cancer including glioblastoma multiforme (GBM). The treatment combines two different approaches to fight cancer: immune modulators and antigen-specific T cells. Immune checkpoint antibodies have been tested on various tumors with good outcomes. GBM is known to express increased levels of certain antigens that can be targeted by antigen-specific T cells. Thus, in this study, the gene-modified T cells specific for GBM antigens will be combined with immune modulatory genes to treat patients in dose escalation cohorts.
