             procedure

          3. Has a documented physician diagnosis of persistent asthma of a minimum of 6 months
             duration that has been stable for at least 4 weeks prior to the screening visit. The
             asthma diagnosis must be in accordance with the National Asthma Education and
             Prevention Program Guidelines Expert Panel Report 3 (EPR3)

          4. Has the ability to self-perform spirometry reproducibly per American Thoracic Society
             (ATS) guidelines

          5. Has forced expiratory volume in 1 second (FEV1) 60-90% predicted for age, height, and
             gender at the screening visit based on the pediatric population standards as per
             protocol.

             Notes: (1) Predicted values of 59.50-59.99% may be rounded up to 60% and 90.01-90.49%
             rounded down to 90%. (2) Patients who at the screening visit fail to meet the
             predicted spirometry values for study entry may be allowed a single attempt to
             re-qualify on another day, but they must re-qualify no later than 16 days following
             the first attempt.

          6. Demonstrates reversible bronchoconstriction as verified by a 15% or greater increase
             in baseline FEV1 within 30 minutes following inhalation of 180 mcg of albuterol to 200
             mcg of fluticasone propionate per day or equivalent), leukotriene modifiers (LTM),
             inhaled cromones, or on β2-agonists alone as needed. The Inhaled corticosteroid (ICS),
             LTM, and cromone doses must have been stable for at least 4 weeks prior to the
             screening visit and are expected to be maintained for the duration of the study

          7. Is maintained on low-dose inhaled corticosteroids ([ICS], less than or equal to 200
             mcg of fluticasone propionate per day or equivalent), leukotriene modifiers (LTM),
             inhaled cromones, or on β2-agonists alone as needed. The ICS, LTM, and cromone doses
             must have been stable for at least 4 weeks prior to the screening visit and are
             expected to be maintained for the duration of the study

          8. Can self-perform peak expiratory flow rate (PEF) measurements with a handheld peak
             flow meter

          9. Has the ability to demonstrate acceptable and reproducible inhalation technique with
             the Spiromax and metered dose inhaler (MDI) devices

               -  Other inclusion criteria apply.

        Exclusion Criteria:

          1. Known hypersensitivity to albuterol or any of the excipients in the inhaler
             formulations (lactose, ethanol, etc.)

          2. Participation (receiving study medication) in any investigational drug trial within
             the 30 days preceding the screening visit or planned participation in another
             investigational drug trial at any time during this trial

          3. History of severe milk protein allergy

          4. History of a respiratory infection or disorder (including, but not limited to
             bronchitis, pneumonia, acute or chronic sinusitis, otitis media, influenza, etc.) that
             has not resolved within 4 weeks preceding the screening visit

          5. Any asthma exacerbation requiring oral corticosteroids within 3 months of the
             screening visit. A patient must not have had any hospitalization for asthma within 6
             months prior to the screening visit.

          6. History of life-threatening asthma that is defined for this protocol as an asthma
             episode that required intubation and/or was associated with hypercapnea, respiratory
             arrest, or hypoxic seizures

          7. Use of any prohibited concomitant medications within the washout period prescribed per
             protocol prior to the screening visit.

          8. Use of any medication for asthma or allergic rhinitis that is prohibited per the
             protocol

          9. The dosage of any required intranasal corticosteroid and/or cromone has not been
             stable for at least 2 weeks prior to the screening visit.

         10. Treated with oral or injectable corticosteroids within the 6 weeks before the
             screening visit.

         11. Initiation of immunotherapy during the study period or dose escalation during the

             must be using a stable (maintenance) dose (90 days or more) to be considered for
             inclusion.
