Predicting peripheral neuropathy risk in patients treated with bortezomib

Neurofilament Light Chain as Biomarker for Bortezomib-induced Peripheral Neuropathy

Observational Odense University Hospital · NCT05781425

This study is trying to see if measuring a specific protein in the blood can help predict the risk of nerve damage in people with multiple myeloma who are being treated with bortezomib.

What this trial studies

This observational study investigates the risk of developing chemotherapy-induced peripheral neuropathy in patients with multiple myeloma undergoing treatment with bortezomib. It aims to enroll 20 patients who will have blood samples drawn before treatment and during their treatment cycles to measure levels of neurofilament light chain (NFL). The primary goal is to correlate NFL levels during treatment with baseline levels, while a secondary goal is to assess the relationship between NFL levels and the cumulative dose of bortezomib. Participants will follow their standard treatment regimen while contributing to this research.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old diagnosed with multiple myeloma who are starting bortezomib treatment and are not candidates for transplantation.

Not a fit: Patients with other underlying cancer diseases, previous neurotoxic chemotherapy, or known polyneuropathy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients at higher risk for peripheral neuropathy, allowing for better management and prevention strategies.

How similar studies have performed: While this approach is focused on a specific patient population, similar studies have shown promise in predicting chemotherapy-related side effects using biomarkers.
