Dataset from An Open Label, Single-arm Phase IV Study to Assess the Efficacy and Safety of Afatinib as Second-line Therapy for Patients With Locally Advanced or Metastatic Non-small Cell Lung Cancer (NSCLC) Harbouring an EGFR Mutation (Del19 or L858R) Who Have Failed First-line Treatment With Platinum-based Chemotherapy

The objectives of this single-arm, open-label trial are to assess the efficacy and safety of afatinib as second line treatment for patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harbouring a common EGFR mutation who have failed first-line platinum-based chemotherapy and to demonstrate that the efficacy and safety are comparable to the results seen in previous trials.
