Randomized Controlled Trial Multicenter StudyDose-response of an extrafine dry powder inhaler formulation of glycopyrronium bromide: randomized, double-blind, placebo-controlled, dose-ranging study (GlycoNEXT).
An extrafine formulation of the long-acting muscarinic antagonist, glycopyrronium bromide (GB), has been developed for delivery via the NEXThaler dry powder inhaler (DPI). This study assessed the bronchodilator efficacy and safety of different doses of this formulation in patients with COPD to identify the optimal dose for further development. ⋯ This study supports the selection of GB 25 μg BID as the minimal effective dose for patients with COPD when delivered with this extrafine DPI formulation.

Randomized Controlled TrialEfficacy and safety of four doses of glycopyrrolate/formoterol fumarate delivered via a metered dose inhaler compared with the monocomponents in patients with moderate-to-severe COPD.
To determine the efficacy and safety of glycopyrrolate/formoterol fumarate metered dose inhaler (GFF MDI 36/9.6, 36/7.2, 18/9.6, 9/9.6 µg) using innovative co-suspension delivery technology, compared with glycopyrrolate (GP) MDI 36 µg and formoterol fumarate (FF) MDI 9.6 µg, in patients with moderate-to-severe COPD. ⋯ While all doses of GFF MDI were superior to GP MDI 36 µg for the primary end-point, in this study neither superiority of GFF MDI to FF MDI 9.6 µg nor a clear dose-response was observed. All treatments were well tolerated with no unexpected safety findings.

Randomized Controlled Trial Multicenter StudyExacerbation recovery patterns in newly diagnosed or maintenance treatment-naïve patients with COPD: secondary analyses of TICARI 1 trial data.
Little is known about the recovery patterns from acute exacerbations of chronic obstructive pulmonary disease (AECOPD) in newly diagnosed or maintenance treatment-naïve patients with COPD. This study describes the course of AECOPD in these patients at the time of treatment for the symptoms of acute respiratory tract infection (RTI). ⋯ A substantial portion of newly diagnosed or maintenance treatment-naïve patients with COPD experience relapse or persistent symptoms following a clinic visit for AECOPD with symptoms of RTI. Whether initiating maintenance therapy could improve outcomes and reduce exacerbation risk requires further study.

Randomized Controlled TrialClinical characteristics of patients newly diagnosed with COPD by the fixed ratio and lower limit of normal criteria: a cross-sectional analysis of the TargetCOPD trial.
Consensus on the definition of airflow obstruction to diagnose COPD remains unresolved. ⋯ In symptomatic individuals, defining airflow obstruction by FR instead of LLN identifies a significant number of individuals who have less respiratory and more cardiac clinical characteristics.

Randomized Controlled TrialSatisfaction, preference and error occurrence of three dry powder inhalers as assessed by a cohort naïve to inhaler operation.
Inhaled medication is central to the treatment of COPD. Various types of inhaler devices, which directly deliver medication to the lung, have been developed. However, patients often exhibit incorrect techniques of inhaler usage. Effectiveness of therapy may be affected by the ease of device usage, size, convenience of use, durability, clarity of instructions and device preferences of patients. This study compares the satisfaction and preference, as well as error occurrence, with the use of Genuair®, Ellipta™ and Breezhaler™ by healthy subjects in Hong Kong. ⋯ Breezhaler seemed to be more comfortable and easy to carry, but users made less critical errors when using Ellipta after reading the instructions only. Genuair provided the clearest indication of correct dose preparation and inhalation.
