Outcome results
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)
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.
Time frame: 0-60 minutes after the exercise challenge performed 2 hours after a single oral dose
Population: The primary efficacy analysis used the modified intention-to-treat (MITT) approach. Patients with data from only one period were not included in the analysis.
