        Exclusion Criteria:

          -  1. Treatment with an EGFR-TKI within 8 days or approximately 5x half-life, whichever
             is the longer, of the first dose of study treatment.

             2. Treatment with cytotoxic chemotherapy, investigational agents or other anticancer
             drugs from a previous treatment regimen or clinical study within 14 days or
             approximately 5x half-life, whichever is the longer, of the first dose of study
             treatment.

             3. Previous treatment with AZD9291, or another EGFR TKI with similar profile, e.g.
             CO-1686 4. Major surgery within 4 weeks of inclusion 5. Radiotherapy treatment to more
             than 30% of the bone marrow or with a wide field of radiation within 4 weeks of
             inclusion 6. Subjects currently receiving (or unable to stop using) potent inhibitors
             or inducers of CYP3A4 7. Any unresolved toxicities from prior therapy greater than
             CTCAE grade 1 (with the exception of alopecia grade 2) at the time of starting study
             treatment.

             steroid dosage for at least 2 weeks prior to start of study treatment.

             9. Any evidence of severe or uncontrolled systemic diseases which in the
             investigator's opinion makes it undesirable for the subject to participate in the
             trial or which would jeopardise compliance with the protocol, or active infection
             including hepatitis B, hepatitis C and human immunodeficiency virus (HIV). Screening
             for chronic conditions is not required.

             10. Gastrointestinal conditions incompatible with swallowing or precluding absorption
             of AZD9291.

             11. Exclude based on any of the following cardiac criteria:

          -  Mean resting corrected QT interval (QTc using Fredericia's formula) > 470 msec

          -  Any clinically important abnormalities in rhythm, conduction or morphology of resting
             ECG (e.g., complete left bundle branch block, third degree heart block, second degree
             heart block)

          -  Any factors that increase the risk of QTc prolongation or risk of arrhythmic events
             such as heart failure, hypokalemia, congenital long QT syndrome, family history of
             long QT syndrome or unexplained sudden death under 40 years of age in first degree
