['fp mdpi', 'fs mdpi', 'flovent hfa', 'advair diskus', 'albuterol/salbutamol hfa']

        Inclusion Criteria:

          1. Best pre-bronchodilator forced expiratory volume in 1 second (FEV1) of greater than
             40% of their predicted normal value.

          2. Patients must have a treatment regimen that includes a short-acting β2 agonist (SABA)
             (albuterol) for use as needed and either an inhaled corticosteroid (ICS) or an
             ICS/long-acting β2 agonist (LABA) as a preventative treatment for a minimum of 8 weeks
             before the SV. Patients currently taking low-dose ICS without LABA are not eligible
             for this study. Patients currently taking low-dose ICS/LABA may only be entered into
             the mid ICS strength. All patients must have been maintained on a stable dose of ICS
             or ICS/LABA for 4 weeks prior to the SV (or pre-SV if necessary) at 1 qualifying doses

          3. To meet reversibility of disease criteria, the patient must demonstrate a ≥12%
             reversibility of FEV1 (and 200 mL for patients aged18 years and older) within 30
             minutes following 4 inhalations of albuterol at the SV. Historic reversibility within
             the past 12 months of the SV may be used to meet this criterion.

          4. Written informed consent/assent is obtained. For adult patients (aged 18 years and
             older, or as applicable per local regulations), the written informed consent form
             (ICF) must be signed and dated by the patient before conducting any study-related
             procedure. For minor patients (aged 12 to 17 years, or as applicable per local
             regulations), the written ICF must be signed and dated by the parent/legal guardian
             and the written assent form must be signed and dated by the patient (if applicable)
             before conducting any study-related procedure. Note: Age requirements are as specified
             by local regulations.

          5. Outpatient >= 12 years of age on the date of consent/assent. .

          6. Asthma diagnosis: The patient has a diagnosis of asthma as defined by the National
             Institutes of Health (NIH). The asthma diagnosis has been present for a minimum of 3
             months and has been stable (defined as no exacerbations and no changes in medication)
             for at least 30 days before providing informed consent.

          7. The patient is able to perform acceptable and repeatable spirometry.

          8. The patient is able to perform peak expiratory flow (PEF) with a handheld peak flow
             meter.

          9. The patient is able to use a metered-dose inhaler (MDI) device without a spacer device
             and a MDPI device.

         10. The patient is able to withhold (as judged by the investigator) his or her regimen of
             ICS or study drug, and rescue medication for at least 6 hours before the SV and before
             all treatment visits where spirometry is performed.

         11. The patient/parent/legal guardian/caregiver is capable of understanding the
             requirements, risks, and benefits of study participation, and, as judged by the
             investigator, capable of giving informed consent/assent and being compliant with all
             study requirements.

         12. SABAs: All patients must be able to replace their current SABA with
             albuterol/salbutamol HFA inhalation aerosol at the SV for use as needed for the
             duration of the study.

         13. Female patients may not be pregnant, breastfeeding, or attempting to become pregnant.

               -  -Other criteria may apply, please contact the investigator for more information

        Criteria for Randomization:

        Patients were randomized into the study if they met all of the following criteria:

          1. The patient continued to be in general good health, meeting the entry criteria.

          2. The patient continued to have a predose/pre-albuterol FEV1 at the randomization visit
             (RV) that was ≥40% of predicted normal.

          3. The patient had no clinically significant abnormal laboratory test results or ECG
             findings at the screening visit.

          4. The patient had no significant changes in asthma medications during run-in, excluding
             the albuterol/salbutamol HFA (90 mcg ex actuator) or equivalent used as rescue
             medication as supplied per protocol.

          5. The patient did not have a upper respiratory tract infection (URI) or lower
             respiratory tract infection (LRI) during the run in period. Patients who developed a
             URI or LRI during the run in period could be discontinued from the study and allowed
             to re-screen 2 weeks after resolution of symptoms.

          6. The patient had no asthma exacerbation during the run in period, defined as any
             worsening of asthma requiring any significant treatment other than rescue
             albuterol/salbutamol HFA (90 mcg ex actuator) or equivalent or the patient's run-in
             MDPI. This included requiring the use of systemic corticosteroids and/or emergency
             department (ED) visit or hospitalization or an increase in the patient's regularly
             prescribed nonsteroidal maintenance treatment. Urgent care/ED visits where the
             treatment was limited to a single dose of nebulized albuterol/salbutamol did not meet
             the criteria of an asthma exacerbation.

          7. The patient had no clinical visual evidence (on oropharyngeal examination) of
             oropharyngeal candidiasis.

          8. The patient did not experience an adverse event that would result in failure to
             continue to meet selection criteria.

          9. The patient did not use any of the prohibited concomitant medications during the run
             in period.

         10. The patient complied with completion of the daily diary, defined as follows:

               -  completion of AM and PM asthma symptom scores on 4 or more of the 7 days
                  immediately preceding the RV.

               -  completion of rescue medication use (whether used or not) on 4 or more of the 7
                  days immediately preceding the RV.

               -  completion of AM peak expiratory flow (PEF) measurements on 4 or more of the 7
                  days immediately preceding the RV.

               -  recording of AM and PM asthma inhalation therapy use on 4 or more of the 7 days
                  immediately preceding the RV.
