Blood tests could reveal who benefits from immunotherapy
NCT ID NCT05091190
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at how well immunotherapy works in people with advanced lung or head and neck cancers. Researchers will take blood samples before and after treatment to measure how the body clears the drug and how tumor cells in the blood change. The goal is to find markers that predict who will respond best to immunotherapy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- immunotherapy
- What this could lead to
- If successful, this could help doctors predict which patients will benefit from immunotherapy, leading to more personalized cancer treatment.
- What could go wrong
- This is an observational study with only 75 participants, so results may not apply to all patients. It measures biomarkers, not direct treatment outcomes.
