Brief Summary

The purpose of this study is to investigate, using an exercise challenge approach, the dose response of levalbuterol HFA MDI in pediatric subjects with asthma

Detailed Description

A randomized, double-blind, active controlled, multicenter, parallel treatment, 3x3 dose level crossover study evaluating the dose response of levalbuterol in pediatric subjects between the ages of 6 and 11, inclusive with exercise induced bronchoconstriction. This study was previously posted by Sepracor Inc. In October 2009, Sepracor Inc. was acquired by Dainippon Sumitomo Pharma., and in October 2010, Sepracor Inc's name was changed to Sunovion Pharmaceuticals Inc.

Study Groups

A

Subjects randomized to the levalbuterol arm will complete 1 of 6 possible randomization sequences containing (a) levalbuterol 45 µg (1 actuation of 45 µg); (b) levalbuterol 90 µg (2 actuation of 45 µg) and (c) levalbuterol 180 µg (4 actuations of 45 µg each). Subjects will receive treatment, according to the randomization sequence, followed by a 5±2 day washout.
