Etoposide Plus Cisplatin Compared With Temozolomide in Patients With Glioblastoma
Temozolomide provided significant and clinically meaningful benefit in MGMT gene promoter methylation glioblastoma. However, in unmethylated patients, the effect of Temozolomide is limited. The aim of this study is to compare the effect of Etoposide plus Cisplatin and Temozolomide in patients with MGMT gene promoter unmethylation glioblastoma.

Evaluation of in Vitro Antitumor Activity of GD2 CAR-T Cells in Glioblastoma
Glioblastoma is a brain tumor with a very poor prognosis, affecting around 2,400 new patients every year. Current treatments do not provide good control of the disease. In view of the therapeutic impasse, it is necessary to develop new strategies. CAR-T cells (Chimeric antigen receptor T cells) represent a highly promising therapy for the treatment of incurable cancers, including glioblastoma. This treatment aims to destroy cancer cells by relying on the patient's own immune system. CAR-T cells are generated from the patient's own immune cells, more specifically T lymphocytes, which are genetically modified to express a tumor-specific receptor on their surface. CAR-T cells bind to...

FET-PET-Guided Management of Pseudoprogression in Glioblastoma
The goal of this diagnostic randomised clinical trial is to determine, in glioblastoma patients with diagnostic uncertainty between pseudoprogression and tumor progression on follow-up MRI after chemoradiation, the added value of a direct [¹⁸F] FET-PET scan for clinical management. The main questions it aims to answer are: - Does the clinical management guided by an additional FET-PET scan leads to fewer unnecessary interventions, compared with management based on MRI only? - Does the clinical management guided by an additional FET-PET scan leads to better health-related quality of life after 12 weeks, compared with management based on MRI only? - ...

Ga-68 Prostate Specific Membrane Antigen PET/CT in Gliomas
As a part of molecular imaging, many PET tracers have been investigated in this regard. Those include 18F-FDG being glucose analogue, 18F-FLT representing nucleoside metabolism, and 18F-FDOPA, 18F-FET, 11C-MET as amino acids analogues. Among these, 18F-FDG is the most commonly used tracer due to its broader use and easy availability. However, high physiological uptake in the brain is a significant limitation. The main limitation of other tracers is the need for onsite cyclotrons for their production, making their availability difficult. So, the search for an ideal modality is still ongoing, and the latest addition to this search is a radio ligand labeled Prostate Specific...

G-CSF After Chemo-radiation in Patients with Glioblastoma
This research study involves the study of granulocyte colony stimulating factor (G-CSF) in patients with MGMT-methylated glioblastoma multiforme (GBM) that are undergoing standard chemoradiation. The study aims to evaluate G-CSF's effects on brain health and cognitive function. The name of the study drugs involved in this study are: - G-CSF (also called Filgrastim) - Temozolomide (TMZ), a standard of care chemotherapy drug

Glioblastoma Imaging Using a Strong Iron-like Bloodpool Contrast Medium?
Rationale: Visualization of tumor spread is of crucial importance when treating patients suffering from glioblastoma (GBM) as the success of tumor resection depends strongly on the extent of tumor infiltration. Current MRI protocols, however, cannot visualize the extent the tumor infiltration. The use of non-toxic, non-dangerous ultrasmall superparamagnetic biodegradable iron oxide (USPIO) particles as a very strong blood pool contrast agent could help visualizing this invisible infiltration Objective: To what extent, do GBMs infiltrate healthy brain tissue and can we use ultrasmall superparamagnetic iron oxide particles to visualize co-opting infiltrating tumor cells in an...

Glioma Adaptive Radiotherapy With Development of an Artificial Intelligence Workflow
Gliomas are common primary brain tumors in adults. Gliomas can be classified into different types based on tumor grade, histopathological features, and molecular characteristics. The common types of diffuse gliomas include glioblastoma, astrocytoma, and oligodendroglioma. The standard treatment for diffuse gliomas includes surgery followed by radiation and chemotherapy. As per standard institutional practice, a uniform dose of radiation is delivered to the disease area and MRI is done before and after the treatment. In this study, MRI and PET scan will be done before starting the treatment and standard dose of radiation will be delivered. The interval imaging will be done...

GPC-3 CAR T CELLS for Recurrent GPC-3 Positive Glioblastoma
The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T-cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat participants with cancers. They have shown promise, but have not been strong enough to cure most participants. The study team has found from previous research that we...

Immunotherapy Targeting of Cytomegalovirus Antigens in Glioblastoma
In Australia, glioblastoma (GBM) has a higher annual fatality rate than a variety of other cancers, such as melanoma, bladder, and kidney tumors. While the 5-year survival rate for other cancers, such as breast and prostate cancer, has increased, there have been no notable advancements in GBM during the past ten years, and the incidence and mortality patterns have barely changed between 1982 and 2011. In particular, GBM poses a challenging therapeutic dilemma for patients and physicians due to its aggressive biology and resistance to available treatments. Recent studies showed that cytomegalovirus (CMV) is expressed in GBM tumors, making it a good target for immunotherapy trials....

Investigational Imaging Technique During Brain Surgery
This early phase I trial tests the safety and reliability of an investigational imaging technique called quantitative oblique back illumination microscopy (qOBM) during brain surgery for detecting brain tumors and brain tumor margins in patients with glioblastoma, astrocytoma, or oligodendroglioma. Surgical margins refer to the edge or border of the tissue removed in cancer surgery. qOBM may be able to assess and reveal brain tumor surgical margins in a more safe and reliable manner.
