---|---|
Experimental: Montelukast/Salmeterol
Period I - Montelukast 5 milligrams (mg) oral tablet once daily and Salmeterol matching placebo dry powder inhaler (DPI) twice daily for 4 weeks followed by a 2-week washout period (salmeterol matching placebo + montelukast matching placebo). Period II - Montelukast matching placebo oral tablet once daily and Salmeterol DPI 50 micrograms (mcg) twice daily for 4 weeks. Inhaled Fluticasone 100 mcg twice daily throughout the study.

- Maximum Post-exercise Percent (%) Fall in FEV1 [ Time Frame: 4 weeks (Weeks 0 to 4 or Weeks 6 to 10) ]The effect of four weeks of treatment with oral montelukast plus inhaled fluticasone, and inhaled salmeterol plus inhaled fluticasone on EIB as measured by the maximum post-exercise percent fall (relative to pre-exercise baseline) in FEV1.
- Area Under the Curve for %-Change From Pre-exercise Baseline FEV1 in Liters (L), From 0 to 20 Minutes (AUC(0-20)) [ Time Frame: 4 weeks (Weeks 0 to 4 or Weeks 6 to 10) ]The effect of a four-week treatment course of oral montelukast plus inhaled fluticasone, compared to inhaled salmeterol plus inhaled fluticasone, on the extent and severity of EIB as measured by the area under the curve from 0 to 20 minutes (AUC0-20) for FEV1 percent change from pre-exercise baseline.
- Maximum FEV1 % Predicted Following First Beta-agonist Use [ Time Frame: 4 weeks (Weeks 0 to 4 or Weeks 6 to 10) ]The effect of a four-week treatment course of oral montelukast plus inhaled fluticasone, compared to inhaled salmeterol plus inhaled fluticasone, on short-acting β-agonist bronchodilation as measured by the maximum FEV1 percent predicted following first β-agonist use.
- Time to Recovery to Within 5% of Baseline FEV1 [ Time Frame: 4 weeks (Weeks 0 to 4 or Weeks 6 to 10) ]The effect of a four-week treatment course of oral montelukast plus inhaled fluticasone, compared to inhaled salmeterol plus inhaled fluticasone, on the extent and severity of EIB as measured by the time to recovery (to within 5 percent of the pre-exercise baseline FEV1) following a standardized exercise challenge.
- Average (Avg) %-Change in FEV1 After First Beta (β)-Agonist Use and Prior to Second β-agonist Use [ Time Frame: 4 weeks (Weeks 0 to 4 or Weeks 6 to 10) ]The effect of a four-week treatment course of oral montelukast plus inhaled fluticasone, compared to inhaled salmeterol plus inhaled fluticasone, on the extent and severity of EIB as measured by the average percent change in FEV1 after first β-agonist intake and prior to second β-agonist use.
