May 30, 2025 updated by: Pfizer

ARIA: Real-world Utilization and Outcomes With Dacomitinib First-line Treatment for EGFR Mutation-positive Advanced Non-small Cell Lung Cancer Among Asian Patients - A Multi-center Chart Review

This is a longitudinal, consecutive case-series, multi-center study with mixed prospective and retrospective data collection. Data will be collected from eligible adults with EGFR mutation-positive advanced non-small cell lung cancer (NSCLC) treated with dacomitinib as first-line therapy from the date of advanced NSCLC diagnosis to the date of death, lost to follow-up, withdrawal of consent or end of study, whichever occurs first.
