Blood test may guide lung cancer therapy, avoiding unnecessary chemo

NCT ID NCT04166487

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study is testing whether a blood test that looks for cancer DNA can tell if immunotherapy alone is working for people with advanced non-small cell lung cancer. If the test shows the cancer is not responding, patients would switch to immunotherapy plus chemotherapy. The goal is to personalize treatment and improve outcomes. The study involves 40 participants and uses the drug pembrolizumab (Keytruda) with or without standard chemotherapy.

What this could mean

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

Active substance

Pembrolizumab (Keytruda) with or without platinum doublet chemotherapy (carboplatin plus pemetrexed or paclitaxel)

What this could lead to

If successful, this approach could allow doctors to personalize treatment for advanced lung cancer, potentially improving outcomes by switching therapy early when needed.

What could go wrong

This is a small pilot study with only 40 participants, so results may not apply to all patients. The blood test may not reliably predict response, and adding chemotherapy increases side effects.
