Summary:

      This is a 2-part study in patients with epidermal growth factor receptor mutation positive
      (EGFRm+) non-small cell lung cancer (NSCLC) whose disease has progressed on treatment with an
      epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI): Part A will
      determine the effect of food on the pharmacokinetics (PK) of AZD9291; Part B will allow
      patients further access to AZD9291 and will provide for additional safety data collection.

      Part A is a randomised, open-label, 2 treatment period crossover study in which patients will
      each receive a single oral dose of AZD9291 (1 x 80 mg tablet) at breakfast time
      (approximately 0800) in each of 2 treatment periods (once immediately following a high fat
      meal [fed], and once in the fasted state [fasted]), with a washout period of 9 days between
      doses.

      Approximately 38 patients are planned to be enrolled and dosed; at least 30 evaluable
      patients will be required to complete Part A (ie, the last PK sample in Treatment Period 2
      [TP 2] has been collected). Additional patients may be enrolled to allow for at least 30
      evaluable patients
    

Eligibility criteria:

        For inclusion in the study patients should fulfil the following criteria:

          1. Male or female, aged at least 18 years.

          2. Able to eat a high-fat meal within a 30-minute period, as provided by the study site.

          3. Histologically or, where appropriate, cytologically confirmed NSCLC.

          4. Radiological documentation of disease progression while on a previous continuous
             treatment with an EGFR TKI. In addition, other lines of therapy may have been given.
             All patients must have documented radiological progression on the last treatment
             administered prior to enrolling in the study.

          5. Confirmation that the tumour harbours an EGFR mutation known to be associated with
             EGFR TKI sensitivity (including G719X, exon 19 deletion, L858R, L861Q).

          6. ECOG performance status 0-1 with no deterioration over the previous 2 weeks.

          7. Patients must have a life expectancy of ≥12 weeks, as estimated at the time of
             screening.

             pregnancy test prior to start of dosing if of child-bearing potential, or must have
             evidence of non-child-bearing potential by fulfilling one of the following criteria at
             screening: Post-menopausal defined as aged more than 50 years and amenorrhoeic for at
             least 12 months following cessation of all exogenous hormonal treatments; Women under
             50 years old would be considered post-menopausal if they have been amenorrhoeic for 12
             months or more following cessation of exogenous hormonal treatments and with
             luteinizing hormone and follicle stimulating hormone levels in the post-menopausal
             range for the institution; Documentation of irreversible surgical sterilisation by
             hysterectomy, bilateral oophorectomy, or bilateral salpingectomy, but not tubal

        fulfilled:

          1. Participation in another clinical study with an IP during the last 14 days (or a
             longer period depending on the defined characteristics of the agents used).

          2. Treatment with any of the following: Treatment with an EGFR TKI w/in 8 days or

             placement of vascular access) within 4 weeks of the first dose; Radiotherapy with a
             limited field of radiation for palliation within 1 week of the first dose of study
             treatment, with the exception of patients receiving radiation to more than 30% of the
             bone marrow or with a wide field of radiation which must be completed within 4 weeks
             of the first dose of study treatment; Patients currently receiving (or unable to stop
             use prior to receiving the first dose of study treatment) medications or herbal
             supplements known to be potent inhibitors of CYP2C8 and of CYP3A4 (at least 1 week
             prior) and potent inducers of CYP3A4 (at least 3 week prior). All patients must try to
             avoid concomitant use of any medications, herbal supplements and/or ingestion of foods

          7. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled
             hypertension and active bleeding diatheses, which in the Investigator's opinion makes
             it undesirable for the patient to participate in the study or which would jeopardise
