Your gut bugs may hold the key to lung cancer therapy

NCT ID NCT04711330

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at whether bacteria in the gut and throat can predict how well stage III lung cancer patients respond to the immunotherapy drug durvalumab after chemoradiation. Researchers will collect stool, throat swabs, and breath samples from 126 participants to see if these microbes can forecast treatment success or side effects. The goal is to find a non-invasive way to personalize treatment decisions.

What this could mean

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

Active substance

durvalumab (immunotherapy)

What this could lead to

If successful, this could lead to a simple stool or throat swab test to predict which patients will benefit from durvalumab and who might experience side effects.

What could go wrong

This is an observational study, not a treatment trial. The microbiome analysis is exploratory, and results may not lead to a reliable test. The study is also relatively small (126 participants).
