Tear Fluid for the Detection of Tumor-associated Extracellular Vesicles in Glioblastoma Patients
NCT07775534
This study is recruiting at 1 US site in 1 state, according to its ClinicalTrials.gov record last updated .
Summary
This clinical trial tests the impact of tear fluid in detecting tumor-associated extracellular vesicles (TEVs) in patients with glioblastoma. Brain tumors release small particles, called TEVs, that may provide information about the tumor, including how it responds to treatment. These particles can be found in cerebrospinal fluid (CSF), which is the fluid that surrounds the brain and spinal cord. Collecting CSF can be difficult and expensive, especially if samples are needed frequently to track these particles over time. Tear fluid is easier to collect than spinal fluid.
