Summary:

      This is a Phase III, multicenter, randomized, double-blind, stratified, parallel-group study
      with three active comparators in subjects with moderate to severe persistent asthma. The
      study consists of a run-in period of 4 weeks, followed by a treatment period of 12 weeks, and
      a follow up contact period of one week. The total duration of the study is 17 weeks. 990
      subjects will be randomized to one of three treatments (FF/VI Inhalation Powder 200/25 mcg
      once daily in the evening; FF/VI Inhalation Powder 100/25 mcg once daily in the evening; FF
      100 Inhalation Powder once daily in the evening) for 12 weeks. In addition, all subjects will
      be supplied albuterol/salbutamol inhalation aerosol at Visit 1 to use as needed for acute
      asthma symptoms throughout the entire study. Subjects will attend four on-treatment visits at
      Weeks 2, 4, 8, and 12 (Visits 4 through 7).

          -  Demonstrate >=12% and >=200 mL reversibility of FEV1 within 10 to 40 minutes following
             4 inhalations of albuterol/salbutamol inhalation aerosol (or an equivalent nebulized
             treatment with albuterol/salbutamol solution) or have documented reversibility testing
             within the 6 months prior to Visit 1 meeting this measure of reversibility. A spacer
             device may be used for testing, if required.

          -  If subject have received ICS for at least 12 weeks prior to Visit 1 and their
             treatment during the 4 weeks immediately prior to Visit 1 consisted of either of the
             two regimens (a or b).a.) A stable mid-dose or high-dose of ICS alone (e.g., >=FP 250
             mcg twice daily) or b.) A stable dose of a mid-dose ICS/LABA combination (e.g.,
             FP/Salmeterol [SALM] 250/50 mcg twice daily) or an equivalent combination via separate
             inhalers.

          -  Use of ICS/LABA are not permitted with LABA on the day of Visit 1.

          -  Must be able to replace current SABA treatment with albuterol/salbutamol aerosol
             inhaler at Visit 1 for use as needed, during the study. Subjects must be able to
             withhold albuterol/salbutamol for at least 6 hours prior to study visits

        Exclusion Criteria:

          -  Upper or lower respiratory tract, sinus, or middle ear that is: not resolved within 4
             weeks of Visit 1 and led to a change in asthma management or, in the opinion of the
             investigator, expected to affect the subject's asthma status or the subject's ability
             to participate in the study.

          -  Any asthma exacerbation that required oral corticosteroids within the 12 weeks prior
             to Visit 1 or, resulted in an overnight hospitalization requiring additional treatment

          -  A subject must not have any clinically significant, uncontrolled condition or disease
             state that, in the opinion of the investigator, would put the safety of the subject at
             risk through study participation or would confound the interpretation of the efficacy
             results if the condition/disease exacerbated during the study

          -  Chronic stable hepatitis B or C are acceptable provided their screening alanine
             transaminase (ALT) is <2x upper limit of normal (ULN) and the y otherwise meet the
