Blood test may tailor lung cancer immunotherapy, sparing unnecessary treatment

NCT ID NCT07759492

First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time

Summary

This trial is testing whether a blood test that detects cancer DNA can guide the use of durvalumab, an immunotherapy, after standard chemoradiotherapy in patients with stage III lung cancer that cannot be removed by surgery. The goal is to see if giving durvalumab only to patients with detectable cancer DNA improves outcomes and avoids overtreating others. Participants will be divided based on the blood test result, with some receiving durvalumab and others not, to compare progression-free survival.

What this could mean

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

Active substance
Durvalumab, an immunotherapy drug, given after chemoradiotherapy, with treatment duration guided by a blood test for cancer DNA (ctDNA).
What this could lead to
If successful, this approach could personalize immunotherapy, giving it only to those who need it, reducing side effects and healthcare costs.
What could go wrong
The trial is in Phase 2, so results are preliminary. The ctDNA test may not accurately predict who benefits, and durvalumab can cause immune-related side effects.
