Ommaya Reservoir Placement at the Time of Biopsy for Longitudinal Biomarker Collection in Patients With Brain Tumors (NCT06322602)

Ommaya Reservoir Placement at the Time of Biopsy for Longitudinal Biomarker Collection

๐ŸŸข Recruiting Observational / Diagnostic ๐Ÿฉบ Clinical Procedure Protocol Sponsor: Mayo Clinic

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This observational trial evaluates the use of Ommaya reservoir placed during a biopsy to collect biomarkers longitudinally in patients with brain tumor. A biomarker is a measurable indicator of the severity or presence of the disease state. An Ommaya reservoir is a small device that's implanted under the scalp. It allows the doctor to take samples of cerebrospinal fluid (CSF) in the future without doing a spinal tap. The identification of biomarkers in CSF is rapidly emerging as a promising minimally invasive approach for monitoring tumor growth and response to therapy. In the future, these biomarkers may be used to help determine what treatments could be most effective and how well a tumor has responded to prior therapy. Currently, limited long-term access to CSF has made it difficult for studies to learn if collecting CSF at different points in the treatment process is useful. Having an Ommaya reservoir placed during a biopsy may allow for longitudinal biomarker collection in patients with brain tumor.
