Final Analysis Data and Exploratory Biomarker Analysis of a Randomized Phase 2 Study of Osimertinib Plus Bevacizumab Versus Osimertinib Monotherapy for Untreated Patients With Nonsquamous NSCLC Harboring EGFR Mutations: The WJOG9717L Study.

ABSTRACT:

Introduction

EGFR tyrosine kinase inhibitors have been the standard treatment for patients with NSCLC who have sensitive EGFR mutations. This study revealed final analysis survival data, biomarkers, and resistance mechanisms of osimertinib plus bevacizumab or osimertinib monotherapy in previously untreated patients with advanced EGFR-positive nonsquamous NSCLC.

Methods

We previously reported the primary results of a randomized, open-label, phase 2 study comparing osimertinib plus bevacizumab with osimertinib monotherapy for this population. In this exploratory analysis using tissue and plasma samples, we evaluated gene profiles at baseline and disease progression or the last dose using targeted deep sequencing.

Results

The median progression-free surviva
