NCT ID NCT04155541
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested the safety and effectiveness of Vizimpro (dacomitinib) in 40 Japanese patients with EGFR-mutated non-small cell lung cancer that could not be surgically removed or had returned. Researchers tracked side effects, especially interstitial lung disease, and measured how well the drug shrank tumors. The study is now complete, and results will help doctors understand how Vizimpro works in real-world Japanese medical practice.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- dacomitinib (Vizimpro)
- What this could lead to
- If results are positive, this could confirm that Vizimpro is a safe and effective option for treating EGFR-mutated lung cancer in Japanese patients.
- What could go wrong
- This was a small, single-country study with only 40 patients, so findings may not apply to broader populations. Side effects like interstitial lung disease are a known risk.
