Real-World tagrisso study shows promise for lung cancer patients
NCT ID NCT03918304
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how well the drug Tagrisso (osimertinib) works and how safe it is for people with a certain type of lung cancer (non-small cell lung cancer with EGFR mutations) in everyday medical practice. Over 900 patients in Korea were observed while taking Tagrisso as their only treatment. The goal was to track side effects and see how long the drug kept the cancer from growing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tagrisso (osimertinib)
- What this could lead to
- If successful, this study could confirm that Tagrisso works well and is safe for a broad range of patients with EGFR-mutant lung cancer in everyday clinical practice.
- What could go wrong
- This is an observational study, not a controlled trial, so results may be less definitive. Side effects like skin rash or diarrhea are possible, and the drug may not work for everyone.
