Brief Summary
The main objective is to evaluate the bronchodilatory efficacy, safety and pharmacokinetic profiles of A006 (Albuterol Dry Powder Inhaler (DPI)), in comparison with those of an active control, Proventil-HFA (Albuterol Metered Dose Inhaler (MDI)), and a Placebo DPI in escalating and cumulative-doses up to 1440 mcg, eight (8) times of the proposed clinical dose.

Outcome Measures
Primary Outcomes (1)
Bronchodilatory efficacy after the escalating and cumulative-doses, up to 1,440 mcg.
Area Under the Curve (AUC)0-t of percent change in Forced Expiratory Volume in 1 second (FEV1), which is defined as the area under curve of post-dose FEV1 percentage changes from the Pre-dose Baseline FEV1 (FEV10) versus time. Doses are at 0, 30, 60 and 90 min.
-15 min predose, 15 min post dose 1, 2 and 3 and 15, 45, 90, 120, 180, 240, 360 min post dose 4
Secondary Outcomes (6)
AUC0-t of change in FEV1
-15, 15 min post 1, 2, and 3, and 15, 90, 120, 240, and 360min post dose 4
Time to onset
0 - 120 min
Peak Response
15 min post dose 1, 2 and 3 and 15, 45, 90, 120, 180, 240, and 360 min post dose 4
Adverse Events
Time 0, 15, 45, 75, 105, 150, 195, 130, 190, 250, 435 minutes post dose 1
Blood Analysis
-15, 10, 25,40, 55, 70, 85, 95, 115, 145, 175, 210, 270, 330, 690 min post dose 1

Study Arms (3)
T
EXPERIMENTALFour doses of A006 taken in 30 minute intervals. Doses will have an escalating number of inhalations (1, 1, 2, and 4 inhalations). Total cumulative Albuterol dose at 90 minutes is 1440 mcg.
R
ACTIVE COMPARATORFour doses of Proventil-HFA taken in 30 minute intervals. Doses will have an escalating number of inhalations (2, 2, 4, and 8 inhalations). Total cumulative Albuterol dose at 90 minutes is 1440 mcg.
P
PLACEBO COMPARATORFour doses of Placebo DPI taken in 30 minute intervals. Doses will have an escalating number of inhalations (1, 1, 2, and 4 inhalations). Total cumulative Albuterol dose at 90 minutes is 0 mcg.
