Randomized Controlled Trial Multicenter Study Comparative StudyEfficacy and safety of coadministration of once-daily indacaterol and glycopyrronium versus indacaterol alone in COPD patients: the GLOW6 study.
Addition of a second bronchodilator from a different pharmacological class may benefit patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) whose symptoms are insufficiently controlled by bronchodilator monotherapy. GLOW6 evaluated the efficacy and safety of once-daily coadministration of the long-acting β2-agonist indacaterol (IND) and the long-acting muscarinic antagonist glycopyrronium (GLY) versus IND alone in patients with moderate-to-severe COPD. ⋯ In patients with moderate-to-severe COPD, once-daily coadministration of IND and GLY provides significant and sustained improvement in bronchodilation versus IND alone from day 1, with significant improvements in patient-centered outcomes.

Randomized Controlled Trial Multicenter StudyEfficacy and safety of combining olodaterol Respimat(®) and tiotropium HandiHaler(®) in patients with COPD: results of two randomized, double-blind, active-controlled studies.
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. ⋯ These studies demonstrated that olodaterol (Respimat(®)) and tiotropium (HandiHaler(®)) provided bronchodilatory effects above tiotropium alone in patients with COPD. In general, both treatments were well tolerated.

Randomized Controlled Trial Multicenter Study Comparative StudyLung function efficacy and symptomatic benefit of olodaterol once daily delivered via Respimat® versus placebo and formoterol twice daily in patients with GOLD 2-4 COPD: results from two replicate 48-week studies.
Two replicate, multicenter, randomized, double-blind, placebo-controlled, parallel-group, Phase III studies investigated the long-term efficacy and safety of once-daily olodaterol via Respimat® versus placebo and formoterol over 48 weeks in patients with moderate to very severe chronic obstructive pulmonary disease receiving usual-care background therapy. Patients received once-daily olodaterol 5 or 10 μg, twice-daily formoterol 12 μg, or placebo. Co-primary end points were forced expiratory volume in 1 second (FEV1) area under the curve from 0-3 hours response, FEV1 trough response, and Mahler transition dyspnea index total score after 24 weeks; secondary end points included St George's Respiratory Questionnaire. ⋯ St George's Respiratory Questionnaire total score was significantly improved with olodaterol, but not formoterol, versus placebo. No safety signals were identified from adverse-event or other safety data. Once-daily olodaterol 5 μg and 10 μg is efficacious in patients with moderate to very severe chronic obstructive pulmonary disease on usual-care maintenance therapy, with a satisfactory safety profile.

Multicenter Study Comparative StudyExperience of fatigue, and its relationship to physical capacity and disease severity in men and women with COPD.
Several differences have been reported in the clinical characteristics of chronic obstructive pulmonary disease (COPD) between men and women. Differences have been found in the association between respiratory symptoms and lung function, and in the factors associated with dyspnea. This raises the question of whether there are differences between the sexes in the relationship between fatigue, the second most prevalent symptom, and the variables of physical capacity and disease severity. ⋯ Exercise capacity and disease severity were associated with fatigue in both men and women. In women, leg fatigue was strongly associated with fatigue, which warrants further investigation.

Multicenter Study Comparative StudyReal-world characterization and differentiation of the Global Initiative for Chronic Obstructive Lung Disease strategy classification.
This study aimed to characterize and differentiate the Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy 2011 cut points through the modified Medical Research Council dyspnea scale (mMRC) and chronic obstructive pulmonary disease (COPD) assessment test (CAT). ⋯ Use of current mMRC or CAT cut points leads to inconsistencies for COPD assessment classification. It is recommended that cut points are aligned and both tools administered simultaneously for optimal patient care and to allow for closer management of movers. Our research may suggest an opportunity to investigate a combined score approach to patient management based on the worst result of mMRC and CAT. The reduced number of remaining movers may then identify patients who have greater impact of disease and may require a more personalized treatment plan.
