Blood test could spare lung cancer patients from needless treatments
NCT ID NCT05889247
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether regular blood tests (liquid biopsies) can better monitor treatment in 350 people with advanced non-small cell lung cancer who are receiving immunotherapy. The goal is to see if this approach reduces the number of ineffective treatments and unnecessary side effects, while also being cost-effective. Participants will be randomly assigned to either standard monitoring or monitoring guided by the blood test.
