Outcome Measures

Primary Outcomes (1)

  • The change from baseline in the maximal percentage decrease in forced expiratory volume in one second (FEV1) after exercise

    Week 2 and Week 4

Secondary Outcomes (1)

  • - Area under the curve (AUC) for FEV1 after exercise challenge, - the length of time for recovery of FEV1 after exercise challenge, - changes in non-challenge pulmonary function tests, and an asthma control questionnaire.

    Week 2 and Week 4

Study Arms (2)

Senicapoc

EXPERIMENTAL
Drug: senicapoc
