Status: Completed

Sponsored by: Sunovion

Clinical Details

Official title: An Efficacy and Safety Study of Levalbuterol, Racemic Albuterol and Placebo in Subjects Twelve Years of Age and Older With Asthma

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: percent change in FEV1 from visit predose averaged over the 8-week double-blind period

Secondary outcome:

area under the FEV1 percent change curve from visit pre-dose and from study baseline curves averaged over the double-blind period

peak percent change in FEV1 from study baseline

peak change in FEV1 from visit predose

peak percent of predicted FEV1

area under the FEV1 curve (AUC)

peak change and peak percent change in FEF25-75% from visit predose

peak change and peak percent change in FVC from visit predose

Detailed description: This was a Phase III, multicenter, randomized, double-blind, placebo- and active-controlled, parallel-group study of up to 9 weeks in duration. Seven days of QID single-blind placebo administration (via MDI) was followed by 56 days of QID double-blind active treatment. Following the run-in period, each subject was randomized to one of the following three treatments: levalbuterol HFA MDI 90 mcg (2 actuations of 45 mcg), racemic albuterol HFA MDI 180 mcg (2 actuations of 90 mcg), or placebo (2 actuations). Subjects were randomized in a 2: 1:1 ratio of levalbuterol to racemic albuterol to placebo. In order to maintain blinding of the device, a placebo dose was administered with each treatment. 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.
