Can a blood test tell who will respond to lung cancer immunotherapy?
NCT ID NCT07608835
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is collecting blood and tumor samples from 200 people with non-small cell lung cancer to find biological markers that predict whether immunotherapy will work. Researchers will compare samples taken before treatment and at the time the disease gets worse. The goal is to better understand why only about 40% of patients respond to current immunotherapies and to identify new targets for treatment.
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 could help doctors predict which lung cancer patients will benefit from immunotherapy and point toward new treatment targets.
- What could go wrong
- This is an observational study, not a treatment trial. It may not lead directly to new therapies, and the findings may not apply to all patients.
