Summary:

      The study is conducted to evaluate the potentially improved patient handling of the ELLIPTA
      Dry Powder Inhaler (DPI). Therefore, the study aims to evaluate errors encountered by subject
      with asthma during handling ELLIPTA DPI relative to two metered dose inhalers (MDI), a GSK
      MDI and the AstraZeneca (AZ) MDI. It is a randomised, multi-centre, open-label, cross-over
      study comparing placebo ELLIPTA DPI with placebo MDI (GSK and AZ) to assess correct inhaler
      use. No active drug will be used in this study in order to prevent any drug-related effects.
      Approximately, 152 subjects will be randomized to receive ELLIPTA DPI inhaler and 152 will be
      randomized to receive one of the MDI inhalers, for use during the first period (P)
      (approximately 28 days). At Visit 2 (Day 28) all subjects previous receiving the ELLIPTA DPI
      will be randomized to receive one of the MDI inhalers and all subjects who received a MDI in
      the previous period will receive the ELLIPTA DPI for use during second period (approximately
      28 days). Subjects will continue taking their asthma maintenance treatment and limited rescue
      albuterol MDI during the entire 56-day study period.

          -  Requires Short-acting-beta-agonist (SABA) for symptom control =<2 days/week. Use of
             SABA prior to exercise for the prevention of exercise induced bronchoconstriction is
             exclusionary.

        Exclusion Criteria:

          -  Subjects with a known or suspected alcohol or drug abuse at Visit 1 which in the
