Study to Evaluate the Effect on Lung Function and ECG When a Combination of Tiotropium Plus Olodaterol is Administered to Patients With COPD Either From a Single Inhaler or Each Compound is Administered After Each Other From Two Different Inhalers

A Randomised, Placebo-controlled, Double-blind, Single Dose, Cross-over Study to Evaluate the Efficacy and Safety of Orally Inhaled Tiotropium + Olodaterol as Both a Fixed Dose Combination and a Free Combination (Both Delivered by the Respimat® Inhaler) in Patients With Chronic Obstructive Pulmonary Disease (COPD)

The primary objective of this study is to evaluate the efficacy and safety of orally inhaled tiotropium and olodaterol as both a fixed dose combination and a free combination with respect to lung function and ECG parameters

Inclusion criteria:

• patients must sign informed consent consistent with ICH-GCP guidelines prior to participation in the trial, which includes medication washout and restrictions.
• Patients must have a diagnosis of COPD and must meet the following spirometric criteria:

Patients must have relatively stable airway obstruction with a post-bronchodilator (10 to 45 minutes after 400mcg salbutamol) FEV1>30% and < 80% of predicted normal (ECSC, GOLD II - III) and a post-bronchodilator FEV1/FVC <70% at Visit 1

• Male or female patients, 40 years of age or older.
• Patients must be current or ex-smokers with a smoking history of more than 10 pack years.
• Patients who have never smoked cigarettes must be excluded.
• Patients must be able to perform technically acceptable pulmonary function tests according to ATS/ERS guidelines and maintain records in a paper diary
• Patients must be able to inhale medication in a competent manner from the RESPIMAT inhaler and from a metered dose inhaler (MDI).
