Overview
The purpose of this Phase III, multicentre, randomized, double-blind, single-dose, 2-period, crossover study is to assess the efficacy and safety of PT027 (budesonide/albuterol sulfate) metered-dose inhaler compared with placebo on exercise-induced bronchoconstriction in adult patients with asthma. Subjects will receive each study treatment on separate visits and undergo a treadmill exercise challenge test so that the effect of study treatment on exercise-induced bronchoconstriction can be evaluated
