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.

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...

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...

Glioblastoma Remote Monitoring and Care - Research Protocol
The purpose of this research is to learn more about how what the Apple watch measures, in terms of walking data, heart rate, breathing rate, and sleep habits, relates to how participants feel. During the course of the treatment, the symptoms participants experience change, and whether the Apple watch can detect these changes. Ultimately, this knowledge is being used to design proactive tools and signatures that can predict complications or symptom changes before they happen.

HSV G207 With a Single Radiation Dose in Children With Recurrent High-Grade Glioma
This study is a clinical trial to assess the efficacy and confirm the safety of intratumoral inoculation of G207 (an experimental virus therapy) combined with a single 5 Gy dose of radiation in recurrent/progressive pediatric high-grade gliomas

Hypofractionation Trial of Re-irradiation in Good Prognosis Recurrent Glioblastoma
Background: Glioblastoma (GBM) is a cancer of the brain. Current survival rates for people with GBM are poor; survival ranges from 5.2 months to 39 months. Most tumors come back within months or years after treatment, and when they do, they are worse: Overall survival drops to less than 10 months. No standard treatment exists for people whose GBM has returned after radiation therapy. Objective: To find a safe schedule for using radiation to treat GBM tumors that returned after initial radiation treatment. Eligibility: People aged 18 years and older with grade 4 GBM that returned after initial...

Identifying Findings on Brain Scans That Could Help Make Better Predictions About Brain Cancer Progression, The GABLE Trial
This phase II trial studies whether different imaging techniques can provide additional and more accurate information than the usual approach for assessing the activity of tumors in patients with newly diagnosed glioblastoma. The usual approach for this currently is magnetic resonance imaging (MRI). This study is trying to learn more about the meaning of changes in MRI scans after treatment, as while the appearance of some of these changes may reflect progressing tumor, some may be due the treatment. Dynamic susceptibility contrast (DSC)-MRIs, along with positron emission tomography (PET) and/or magnetic resonance (MR) spectroscopy, ...

Imaging and Biological Markers for Prediction and Identification of Glioblastoma Pseudoprogression: a Prospective Study.
The goal of this interventional study is the development and validation of imaging markers, MRI and PET, plasma biomarkers, and/or cell markers that could support clinicians and researchers in differentiating pseudoprogression from true tumor progression in routine clinical activities and clinical trials in patients affected by glioblastoma. The endpoints of the study are: - the elaboration of predictive models using imaging advanced biomarkers, PET and MRI, biological serum markers, and cancer cell derived makers to differentiate tumor pseudoprogression or real progression in patients affected by glioblastoma who...

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, ...

Improving Understanding of Glioblastoma Through Preservation of Biologically Active Brain Tissue
To collect and preserve glioblastoma tissue during standard of care tumor resection surgery and blood for future molecular and genetic testing. Tissue for research will be collected from three different regions within the same tumor to study how these regions differ in their structure, DNA, and RNA and also to compare the data obtained from this testing to imaging data found in the medical record. The goal of this study is to help us better understand what the glioblastoma tumor tissue looks like and how it functions. This understanding can lead to new therapies for the treatment of glioblastoma in the future.
