Asthma, Exercise-Induced
Conditions
Brief summary
The purpose of this study is 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.
Interventions

Participant flow
Recruitment details
Patients were randomized at 8 sites (7 in the US and 1 in Peru). Primary therapy period: May to October 2004.
Pre-assignment details
Patients who required excluded medications, or did not meet FEV1 criteria during the prestudy period were excluded from randomization. Patients who required a β-agonist after the exercise challenge and did not meet FEV1 criteria within 30 minutes of treatment were also excluded.

Time frame: Pre-exercise baseline measurement and 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.
