12 / 48 Week Pivotal PFT vs PBO in COPD I

Study Overview
=================
Brief Summary
-----------------
This primary objective of this study is to compare two doses of BI 1744 CL inhalation solution delivered by the Respimat® inhaler once daily to placebo in patients with chronic obstructive pulmonary disease (COPD).
