Efficacy and safety of combining olodaterol Respimat(®) and tiotropium HandiHaler(®) in patients with COPD: results of two randomized, double-blind, active-controlled studies.

ABSTRACT:

Background

Combining bronchodilators with different mechanisms of action may improve efficacy and reduce risk of side effects compared to increasing the dose of a single agent in chronic obstructive pulmonary disease (COPD). We investigated this by combining two long-acting bronchodilators: once-daily muscarinic antagonist tiotropium and once-daily β2-agonist olodaterol.

Methods

Two replicate, double-blind, randomized, 12-week studies (ANHELTO 1 [NCT01694771] and ANHELTO 2 [NCT01696058]) evaluated the efficacy and safety of olodaterol 5 μg once daily (via Respimat(®)) combined with tiotropium 18 μg once daily (via HandiHaler(®)) versus tiotropium 18 μg once daily (via HandiHaler(®)) combined with placebo (via Respimat(®)) in patients with moderate to severe COPD.
