Dataset from A Phase 1b Study of Intermittent Administration of High Doses of the Irreversible EGFR Inhibitor Afatinib as a Means of Achieving Plasma Levels Active Against Non-small Cell Lung Cancer With Known T790M Mutations

This trial is divided into Part A and Part B. The primary objective of Part A is to establish the Maximal Tolerated Dose of intermittent high dose afatinib. The primary objective of Part B is to assess the response rate of patients with non-small cell lung cancer with EGFR T790M mutations to a dose of intermittent afatinib established in Part A. The secondary objective is to explore tumor response and tumor-derived biological markers of response to afatinib, as well as pharmacokinetic parameters of afatinib.
