NCT00534976

Brief Summary

This study will see if there is a change in breathing after exercising when the child receives study drug ( montelukast or placebo). Breathing will be measured by a spirometer before exercising and measured again several times after exercising.

Outcome Measures

Primary Outcomes (1)

  • Maximum Percent Fall in Forced Expiratory Volume in 1 Second (FEV1) After Exercise Challenge at 2 Hours Postdose

    Maximum Percent Fall in FEV1 was defined as the % change from pre-exercise baseline FEV1 to the lowest FEV1 within 60 mins (minutes) after exercise. Spirometry measurements were taken 5 mins prior to each exercise challenge and immediately, 5, 10, 15, 30, 45, \& 60 mins after each exercise challenge. The 2-hour exercise challenges occurred 2 hours after the witnessed dose of study medication. The calculation used to produce the results was \[100\*(1-(X/Y))\] where X= the lowest FEV1 within 60 mins after exercise \& Y= pre-exercise baseline FEV1. Smaller values mean greater response to therapy.

    Pre-exercise baseline and 0-60 minutes after the exercise challenge performed 2 hours post-dose

Secondary Outcomes (7)

  • Maximum Percent Fall in FEV1 After Exercise Challenge at 24 Hours Post-dose

    Pre-exercise baseline and 0-60 minutes after the exercise challenge performed 24 hours post-dose

  • Area Under the Curve for FEV1 Percent Fall From Pre-exercise Baseline to 60 Minutes Following Exercise Challenge (AUC0-60 Min) at 2 Hours Post-dose

    Pre-exercise baseline to 60 minutes after the exercise challenge performed 2 hours post-dose

  • Area Under the Curve for FEV1 Percent Fall From Pre-exercise Baseline to 60 Minutes Following Exercise Challenge (AUC0-60 Min) at 24 Hours Post-dose

    Pre-exercise baseline to 60 minutes after the exercise challenge performed 24 hours post-dose

  • Time to Recovery From Maximum Percent Fall in FEV1 at 2 Hours Post-dose

    0-60 minutes and 0-90 minutes after the exercise challenge at 2 hours postdose

  • Time to Recovery From Maximum Percent Fall in FEV1 at 24 Hours Post-dose

    0-60 minutes and 0-90 minutes after the exercise challenge at 24 hours postdose

  • +2 more secondary outcomes
