Primary outcomePrimary: 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) — 13.15; 10.46; 21.86 Percent Change from Baseline
Summary
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.

Eligibility Criteria
Inclusion Criteria
- Physician-diagnosed exercise-induced bronchospasm
Exclusion Criteria
- Patient is, other than asthma, not in good, stable health. The Primary Investigator will evaluate whether there are other reasons why the patient may not participate.
