The Whole Picture of First-Line Osimertinib for EGFR Mutation-Positive Advanced NSCLC: Real-World Efficacy, Safety, Progression Pattern, and Posttreatment Therapy (Reiwa Study).

ABSTRACT:

Introduction

Osimertinib is used as the first-line treatment for EGFR mutation-positive NSCLC. Nevertheless, its efficacy and safety in clinical practice remain to be fully elucidated and the pattern of progression and the optimal subsequent treatment after osimertinib remains unclear.

Methods

This was a multicenter prospective observational study. EGFR mutation-positive patients with NSCLC who started first-line osimertinib from September 2018 to August 2020 were enrolled and followed up until August 2022.

Results

A total of 583 patients received osimertinib. The median progression-free and overall survival were 20.0 (95% confidence interval [CI]: 17.6-21.7) months and 41.0 (95% CI: 37.1-44.1) months, respectively. Grade 3 or worse adverse events were observed in 136
