Using amantadine to monitor glioblastoma progression

Acetyl-Amantadine as a Biomarker in Patients With Glioblastoma

Not applicable Interventional CancerCare Manitoba · NCT04530006

This study is testing if measuring a substance called acetyl-amantadine in blood or urine can help track the progression of glioblastoma in patients.

What this trial studies

This study investigates the use of acetyl-amantadine as a potential biomarker for monitoring glioblastoma multiforme (GBM) in patients. It focuses on the enzyme spermine/spermidine n-acetyl transferase (SSAT1), which is overproduced in GBM cells, leading to increased metabolism of amantadine. By measuring the levels of acetyl-amantadine in blood or urine, the study aims to correlate these levels with tumor burden as assessed by MRI. The goal is to establish a safe and effective method for early detection and monitoring of GBM progression.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with pathologically confirmed glioblastoma who are scheduled for radiation and/or chemotherapy.

Not a fit: Patients with known hypersensitivity to amantadine or significant renal impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel and non-invasive method for monitoring glioblastoma progression, potentially improving patient outcomes.

How similar studies have performed: While the use of biomarkers in cancer monitoring is a growing field, this specific approach using acetyl-amantadine in glioblastoma is novel and has not been extensively tested in prior studies.
