Purpose

Treatment efficacy of osimertinib will be assessed in patients with lung cancer harboring activating epidermal growth factor receptor (EGFR) mutations (cohort 1) and those harboring T790M (cohort 2) which were detected from circulating tumor DNA

Detailed Description

      This is a phase II, open-label, single centre study of AZD9291 administered orally in
      patients with advanced lung cancer with activating mutations of EGFR gene with or without
      T790M which were detected from circulating tumor DNA. EGFR-TKI naïve patients with activating
      EGFR mutation will be enrolled in cohort 1. Patients with acquired resistance to prior EGFR
      tyrosine kinase inhibitor (TKI) due to T790M mutation is going to be enrolled in cohort 2.

             preclude adequate absorption of AZD9291

         11. History of hypersensitivity to AZD9291 (or drugs with a similar chemical structure or
             class to AZD9291) or any excipients of these agents

             birth control and females who are pregnant or breastfeeding or have a positive (urine
             or serum) pregnancy test prior to study entry

         13. Judgment by the Investigator that the patient should not participate in the study if
