Blood test may predict nerve damage from common chemo drug

NCT ID NCT06490159

First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time

Summary

This study investigates whether a blood test can predict which stomach cancer patients will develop nerve damage (peripheral neuropathy) from the chemotherapy drug paclitaxel. Paclitaxel is a standard second-line treatment for advanced gastric cancer, but nerve damage is a common and troublesome side effect. Researchers aim to develop a liquid biopsy assay to identify high-risk patients before treatment, enabling more personalized and safer chemotherapy choices. The study enrolls 150 adults with unresectable or recurrent gastric cancer who have progressed on first-line therapy.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Paclitaxel
What this could lead to
If successful, this could lead to a simple blood test that identifies patients at high risk for nerve damage before starting paclitaxel, allowing doctors to choose safer treatments.
What could go wrong
This is an early-stage observational study focused on prediction, not treatment. The blood test may not prove accurate enough for clinical use, and it does not prevent or cure neuropathy.
