Lung cancer drug levels under the microscope

NCT ID NCT04557007

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

Summary

This observational study looked at how much of the immunotherapy drug pembrolizumab stays in the blood of patients with advanced non-small cell lung cancer. Researchers measured drug levels and immune responses in 80 patients receiving pembrolizumab alone or with chemotherapy. The goal was to see if drug concentration relates to how well the cancer responds or to side effects.
