Brief Summary:
This is a multicenter, randomized, double-blind, double-dummy, placebo-controlled, single-dose, 5-treatment, 5-period, 5-way crossover study in pediatric patients with persistent asthma. The primary purpose of this study is to compare the efficacy and safety of Albuterol Spiromax with that of ProAir HFA in pediatric asthma patients at 2 delivered dose levels equivalent to 90 mcg and 180 mcg of albuterol base.

Condition or disease Intervention/treatment Phase
Asthma Drug: Albuterol Spiromax Drug: ProAir HFA Drug: Placebo Phase 2

Detailed Description:
The study consists of a screening visit (SV) followed by up to 16 days by a treatment period comprising 5 visits (TV1-TV5). The treatment period visits will each be separated by a washout period lasting 2-7 days. During each treatment period visit, the forced expiratory volume in 1 second (FEV1) will be determined at 30 minutes and again immediately prior to the commencement of study medication administration, and 5, 15, 30, 45, 60, 120, 180, 240, 300, and 360 minutes after completion of study medication administration.

Primary Outcome Measures :
  1. Baseline-Adjusted Area-Under-The-Percent-Predicted Forced Expiratory Volume In 1 Second (FEV1) Versus Time Curve Over 6 Hours Post-Dose [ Time Frame: Treatment visits 1-5 (approximately days 1, 6, 11, 16, and 21); -35 and -5 minutes prior to dosing and 5 (±2), 15 (±5), 30 (±5), 45 (±5), 60 (±5), 120 (±5), 180 (±5), 240 (±5), 300 (±5), and 360 (±5) minutes after the completion of study drug administrati ]

    Percent predicted FEV1: measured FEV1 as a percent of the "predicted values" for the patients of similar characteristics. Predicted FEV1 values were computed and adjusted for age, height, and gender for patients aged 4-5 years (Eigen et al 2001) and for patients aged 6-11 years (Quanjer et al 1995) using ATS/European Thoracic Society (ERS) criteria applicable to pediatric patients (ATS/ERS 2007).

    The percent predicted FEV1 (PPFEV1) area under the curve (AUC)0-6 was calculated using the linear trapezoidal rule, and baseline adjustment was made by subtracting the average of the 2 pre-dose PPFEV1 values from each post-dose PPFEV1 determination.



Secondary Outcome Measures :
  1. Baseline-Adjusted Area-Under-The- Forced Expiratory Volume In 1 Second (FEV1) Versus Time Curve Over 6 Hours Post-Dose (FEV1 AUC0-6) [ Time Frame: Treatment visits 1-5 (approximately days 1, 6, 11, 16, and 21); -35 and -5 minutes prior to dosing and 5 (±2), 15 (±5), 30 (±5), 45 (±5), 60 (±5), 120 (±5), 180 (±5), 240 (±5), 300 (±5), and 360 (±5) minutes after the completion of study drug administrati ]
    FEV1 AUC0-6 was calculated using the linear trapezoidal rule, and baseline adjustment was made by subtracting the average of the 2 pre-dose FEV1 values from each post-dose FEV1 determination.

  2. Participants With Treatment-Emergent Adverse Events [ Time Frame: Day 1 up to Day 35 ]

    Adverse events (AEs) summarized in this table are those that began or worsened after treatment with study drug (treatment-emergent AEs). An adverse event was defined in the protocol as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator as mild (no limitation of usual activities), moderate, or severe (inability to carry out usual activities).

    Relation of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent the previously listed serious outcomes.
