DSC-MRI for Recurrent Glioblastoma
Trial Summary
What is the purpose of this trial?
This phase II trial studies how well dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSC-MRI) works in measuring relative cerebral blood volume (rCBV) for early response to bevacizumab in patients with glioblastoma that has come back. DSC-MRI may help evaluate changes in the blood vessels within the cancer to determine a patient?s response to treatment.
Do I need to stop my current medications for this trial?
The trial protocol does not specify whether you need to stop taking your current medications. However, it does require that you have not been previously treated with immunotherapies.
What data supports the effectiveness of the drug Bevacizumab for treating recurrent glioblastoma?
Research shows that using a special type of MRI scan called DSC-MRI to measure blood flow in the brain can help predict how well patients with recurrent glioblastoma respond to Bevacizumab. This drug, which targets blood vessel growth in tumors, has shown promise in improving outcomes for these patients.12345
Is bevacizumab safe for humans?
Bevacizumab has been studied for safety in humans, and while it is generally considered safe, it can have serious side effects. Some of these include gastrointestinal perforation (a hole in the stomach or intestines), venous thromboembolism (blood clots in veins), and intracranial hemorrhages (bleeding in the brain), especially in patients with glioblastoma. It's important to monitor for these risks and manage them appropriately.36789
How is the drug Bevacizumab unique for treating recurrent glioblastoma?
Bevacizumab is unique because it targets and inhibits VEGF (a protein that promotes blood vessel growth), which is crucial in reducing the blood supply to tumors. This approach is different from traditional treatments, as it focuses on cutting off the tumor's blood supply rather than directly attacking the tumor cells.123510

Eligibility Criteria
This trial is for adults with recurrent glioblastoma who can undergo MRI scans and have not been treated with immunotherapies. They must have a Karnofsky performance status of at least 70, no severe allergies to gadolinium, no MR-incompatible implants, and adequate organ function. Pregnant or breastfeeding women are excluded.Inclusion Criteria
