Primary Outcome Measures
NameTimeMethod
Maximum Percent Fall in Forced Expiratory Volume in 1 Second (FEV1) After Exercise Challenge at 2 Hours Post-dose in Patients With Exercise-Induced Bronchoconstriction (EIB)0-60 minutes after the exercise challenge performed 2 hours after a single oral dose

In patients with EIB, the percent change from pre-exercise baseline FEV1 to the lowest FEV1 within 60 minutes after exercise challenge (2 hours post-dose). The FEV1 measurement obtained 5 minutes before the exercise challenge was the baseline, and was specific to each exercise challenge.

Secondary Outcome Measures
NameTimeMethod
Number of Patients Requiring β-Agonist Rescue Medication After Exercise Challenge at 2 Hours Postdose0-90 minutes after the exercise challenge performed at 2 hours postdose
Number of Patients Requiring β-Agonist Rescue Medication After Exercise Challenge at 8.5 Hours Postdose0-90 minutes after the exercise challenge performed at 8.5 hours postdose
Number of Patients Requiring β-Agonist Rescue Medication After Exercise Challenge at 24 Hours Postdose0-90 minutes after the exercise challenge performed at 24 hours postdose
Maximum Percent Fall in FEV1 After Exercise Challenge at 8.5 Hours Post-dose in Patients With EIB0-60 minutes after the exercise challenge performed 8.5 hours after a single oral dose

In patients with EIB, the percent change from pre-exercise baseline FEV, to the lowest FEV1 within 60 minutes after exercise challenge (8.5 hours post-dose). The FEV1 measurement obtained 5 minutes before the exercise challenge was the baseline, and was specific to each exercise challenge.

Maximum Percent Fall in FEV1 After Exercise Challenge at 24 Hours Post-dose in Patients With EIB0-60 minutes after the exercise challenge performed 24 hours after a single oral dose

In patients with EIB, the percent change from pre-exercise baseline FEV, to the lowest FEV1 within 60 minutes after exercise challenge (24 hours post-dose). The FEV1 measurement obtained 5 minutes before the exercise challenge was the baseline, and was specific to each exercise challenge.

Area Under the Curve for FEV1 Percent Change From Preexercise Baseline During the 60 Minutes Following Exercise Challenge (AUC 0-60 Min) at 2 Hours Postdose0-60 minutes after the exercise challenge at 2 hours postdose

The measure included only the area below the pre-exercise

baseline

Area Under the Curve for FEV1 Percent Change From Preexercise Baseline During the 60 Minutes Following Exercise Challenge (AUC 0-60 Min) at 8.5 Hours Postdose0-60 minutes after the exercise challenge at 8.5 hours postdose

The measure included only the area below the pre-exercise baseline

Area Under the Curve for FEV1 Percent Change From Preexercise Baseline During the 60 Minutes Following Exercise Challenge (AUC 0-60 Min) at 24 Hours Postdose0-60 minutes after the exercise challenge at 24 hours postdose

The measure included only the area below the pre-exercise baseline

Time to Recovery From Maximum Percentage Decrease in FEV1 After Exercise Challenge at 2 Hours PostdoseExercise challenge at 2 hours postdose

The time to recovery from maximum percent fall is the duration between the time at which the maximum percent fall in FEV1 after exercise challenge occurs and the time when FEV1 returns to within 5% of the preexercise baseline for the first time.

Time to Recovery From Maximum Percentage Decrease in FEV1 After Exercise Challenge at 8.5 Hours PostdoseExercise challenge at 8.5 hours postdose

The time to recovery from maximum percent fall is the

duration between the time at which the maximum percent fall in FEV1 after exercise challenge occurs and the

time when FEV1 returns to within 5% of the preexercise baseline for the first time.

Time to Recovery From Maximum Percentage Decrease in FEV1 After Exercise Challenge at 24 Hours PostdoseExercise challenge at 24 hours postdose

The time to recovery from maximum percent fall is the

duration between the time at which the maximum percent fall in FEV1 after exercise challenge occurs and the

time when FEV1 returns to within 5% of the preexercise baseline for the first time.
