Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Fluticasone Furoate

Daily inhalation of 100mcg fluticasone furoate for 7 days Response to methacholine induced bronchoconstriction will be assessed on Day 1 before first inhalation of study treatment (baseline) and again at 24, 72 and 168 hours.

The change in airway responsiveness to methacholine will be determined as a dose shift in methacholine PD20 from baseline to each of the three timepoints

Group Type EXPERIMENTAL

Fluticasone furoate

Intervention Type DRUG

Inhaled corticosteroid

Matching Placebo

Daily inhalation of inactive placebo comparator for 7 days Response to methacholine induced bronchoconstriction will be assessed on Day 1 before first inhalation of study treatment (baseline) and again at 24, 72 and 168 hours.

The change in airway responsiveness to methacholine will be determined as a dose shift in methacholine PD20 from baseline to each of the three timepoints
