To Evaluate the Long-term Safety of (R,R)-Formoterol in Subjects With COPD

This was a multicenter, open-label, randomized, active controlled, parallel group chronic safety study of arformoterol 50 mcg once daily over a period of 12 months in subjects with COPD. 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.

Inclusion criteria

In order to qualify for participation, subjects must meet the following criteria:

• Must give written informed consent prior to participation. Women of childbearing potential must also sign the Women of Childbearing Potential Addendum.
• Must be willing to comply with study procedures and visit schedule
• Male or female >35 years of age
• Female subjects <65 years of age must have a serum pregnancy test conducted at Visit 1 and confirmed negative prior to randomization. Subjects of childbearing potential must be using an acceptable method of birth control.
• Female subjects who are considered not of childbearing potential must be: (1) documented surgically sterile, OR (2) postmenopausal
• Have a primary diagnosis of COPD, which may include components of chronic bronchitis and/or emphysema. Diagnosis can be made during the screening process.
• Have a minimum smoking history of 15 pack-years (pack-years = the number of cigarette packs per day times the number of years)
• Medical Research Council (MRC) Dyspnea Scale Score >2
• Have a baseline FEV1 <65% of predicted normal value and >0.70 L documented prior to randomization
• Have an FEV1/FVC ratio <70% documented prior to randomization.
• Have a chest x-ray that is consistent with the diagnosis of COPD and taken <3 months prior to Visit 1. If there is no chest x-ray taken 3 months prior to Visit 1, a chest x-ray will be performed prior to Visit 2.
• Be able to complete all study questionnaires and logs reliably

• Have a known sensitivity to (R,R)-formoterol, ipratropium, salmeterol or albuterol or any of the excipients contained in any of these formulations
• Have clinically significant abnormalities that may interfere with the metabolism or excretion of the study drug
• Have a history of substance abuse or drug abuse within 12 months of Visit 1 or with a positive urine drug screen at the screening visit
• Subject with clinically significant abnormal laboratory values
• Subject with clinically significant abnormal 12-lead ECG that may jeopardize the subject's ability to complete the study
• Subject using any prescription drug for which concomitant beta-agonist administration is contraindicated
