New blood test aims to predict which cancer patients will benefit from immunotherapy
NCT ID NCT07246759
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is developing a blood test called NeutroFlow that measures specific immune cells (neutrophils) to predict whether cancer patients will benefit from immunotherapy. Researchers will collect blood samples from 600 patients with several types of cancer before they start treatment. The goal is to create a tool that helps doctors personalize cancer care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this blood test could help doctors decide which patients are most likely to benefit from immunotherapy, avoiding unnecessary treatments.
- What could go wrong
- This is an early-stage study to develop and validate a test, not a treatment. The test may not accurately predict outcomes for all patients or cancer types.
