Afatinib in NSCLC With HER2 Mutations: Results of the Prospective, Open-Label Phase II NICHE Trial of European Thoracic Oncology Platform (ETOP)

摘要

Introduction: Mutations in erb-b2 receptor tyrosine kinase 2 (HER2) oncogene are observed in approximately 3% of lung adenocarcinomas or mixed tumors with adenocarcinoma component. Activity of various biologically distinct HER2 inhibitors, including the pan-HER inhibitor afatinib, has been reported in several retrospective trials or small series in advanced pretreated NSCLC with HER2 mutations. We report the first prospective evaluation of afatinib for the treatment of this molecularly defined entity.
