Fixed Dose Combination Versus Free Combination of Tiotropium and Olodaterol in COPD

Overview

This is a 4-week, multicenter, randomized, double-blind, parallel group and active controlled study. Patients will be randomized (1 to 1 ratio) to a 4-week double-blind treatment period of either FDC (fixed-dose combination) of tiotropium + olodaterol (5/5 µg) plus placebo or the free combination of tiotropium 5 µg and olodaterol 5 µg; all administered via the Respimat® inhaler. The purpose is to show non-inferiority between the FDC and the free combination of tiotropium and olodaterol in patients with COPD.

Full Title of Study: “A 4-week, Randomised, Double-blind, Parallel Group Study to Evaluate the Efficacy and Safety of Tiotropium + Olodaterol Fixed Dose Combination (5/5 µg) Delivered by the Respimat® Inhaler Versus the Free Combination of Tiotropium 5 µg and Olodaterol 5 µg Delivered by Separate Respimat® Inhalers in Patients With Chronic Obstructive Pulmonary Disease (COPD)”

Clinical Trial Outcome Measures

Primary Measures

  • Trough Forced Expiratory Volume in 1 Second (FEV1) (in Liter) After 28 Days of Treatment
    • Time Frame: Day 29
    • This outcome measure presents FEV1 after 28 days of treatment (measurement on Day 29). Trough FEV1 was defined as the FEV1 value at the end of the dosing interval (24 hours), and was measured at 24 hours (+/- 10 minutes) after trial medication administration at Visit 5. The FEV1 measurement at Visit 4, which was 24 hours after the last open-label run-in treatment intake and 15 minutes before the first double-blind study drug intake was the baseline measurement.

Secondary Measures

  • Trough Forced Vital Capacity (FVC) (in Liter) After 28 Days of Treatment
    • Time Frame: Day 29
    • This outcome measure presents trough FVC after 28 days of treatment (measurement on Day 29). The FVC measurement at Visit 4, which was 24 hours after the last open-label run-in treatment intake and 15 minutes before the first double-blind study drug intake was the baseline measurement for FVC.
  • Chronic Obstructive Pulmonary Disease (COPD) Assessment Test™ (CAT) Score on Day 28
    • Time Frame: Day 28
    • This outcome measure presents COPD assessment test score on Day 28. The COPD Assessment Test™ is a short 8-item questionnaire for assessment and monitoring of COPD health status in routine practice. Its scale is 0-40 (high score = poor health). The CAT measurement on Visit 4 prior to the first dose of double-blind study drug was the baseline for CAT.
