Montelukast Compared With Placebo and Salmeterol in Exercise-Induced Bronchoconstriction - Full Text View

Purpose

To determine the effect of an approved medication being studied in support of a new approach in the prevention of exercise-induced asthma (a worsening of asthma caused by exercise, also known as exercise-induced bronchospasm), in patients who have a history of worsening asthma after exercise.

Primary Outcome Measures:

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) [ Time Frame: 0-60 minutes after the exercise challenge performed 2 hours after a single oral dose ] [ Designated as safety issue: No ]
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:

Number of Patients Requiring β-Agonist Rescue Medication After Exercise Challenge at 2 Hours Postdose [ Time Frame: 0-90 minutes after the exercise challenge performed at 2 hours postdose ] [ Designated as safety issue: No ]
Number of Patients Requiring β-Agonist Rescue Medication After Exercise Challenge at 8.5 Hours Postdose [ Time Frame: 0-90 minutes after the exercise challenge performed at 8.5 hours postdose ] [ Designated as safety issue: No ]
Number of Patients Requiring β-Agonist Rescue Medication After Exercise Challenge at 24 Hours Postdose [ Time Frame: 0-90 minutes after the exercise challenge performed at 24 hours postdose ] [ Designated as safety issue: No ]
Maximum Percent Fall in FEV1 After Exercise Challenge at 8.5 Hours Post-dose in Patients With EIB [ Time Frame: 0-60 minutes after the exercise challenge performed 8.5 hours after a single oral dose ] [ Designated as safety issue: No ]
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 EIB [ Time Frame: 0-60 minutes after the exercise challenge performed 24 hours after a single oral dose ] [ Designated as safety issue: No ]
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 Postdose [ Time Frame: 0-60 minutes after the exercise challenge at 2 hours postdose ] [ Designated as safety issue: No ]
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 Postdose [ Time Frame: 0-60 minutes after the exercise challenge at 8.5 hours postdose ] [ Designated as safety issue: No ]
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 Postdose [ Time Frame: 0-60 minutes after the exercise challenge at 24 hours postdose ] [ Designated as safety issue: No ]
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 Postdose [ Time Frame: Exercise challenge at 2 hours postdose ] [ Designated as safety issue: No ]
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 Postdose [ Time Frame: Exercise challenge at 8.5 hours postdose ] [ Designated as safety issue: No ]
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 Postdose [ Time Frame: Exercise challenge at 24 hours postdose ] [ Designated as safety issue: No ]
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.
