However, studies on the impact of comorbid A/D on responses to bronchodilators are limited.Methods: This post hoc analysis of pooled data (N=861) from the GOLDEN 3 and 4 studies compared the efficacy and safety of nebulized glycopyrrolate (GLY) 25 μg in patients with moderate-to-very-severe COPD, grouped by self-reported A/D. Changes in forced expiratory volume in 1 second (FEV1) and health-related quality of life determined by St George’s Respiratory Questionnaire (SGRQ) scores in patients with or without comorbid A/D (A/D [+] or A/D [–]) were examined following 12 weeks of GLY 25 μg twice-daily (BID) or placebo treatment.Results: A/D (+) patients were predominantly female, younger, included a higher proportion of current smokers, and had higher baseline SGRQ scores compared with the A/D (–) group. At 12 weeks, GLY resulted in placebo-adjusted improvements from baseline in FEV1 of 46.9 mL (p=0.19; not significant) and 106.7 mL (p< 0.0001), in the A/D (+) and A/D (–) groups, respectively. Improvements were observed with GLY compared to placebo in SGRQ scores, regardless of baseline A/D status; the placebo-adjusted least squares mean change from baseline in SGRQ total scores was – 3.16 (p> 0.05) and – 3.34 (p< 0.001), for the A/D (+) and A/D (–) groups, respectively. Despite numerical improvements in SGRQ scores with GLY in the A/D (+) group, a higher response to placebo was observed. GLY was generally well tolerated throughout 12 weeks of treatment; incidence of adverse events was higher in the A/D (+) group compared with the A/D (–) group in both treatment arms.Conclusion: GLY 25 μg BID resulted in numerical improvements in FEV1, SGRQ total scores and SGRQ responder rates in patients with moderate-to-very-severe COPD, regardless of A/D status at baseline; significant improvements were noted only in the A/D (+) group. The results emphasize the importance of considering underlying comorbidities including A/D when evaluating the efficacy of COPD treatments.Keywords: anxiety, COPD, depression, LAMA, nebulized glycopyrrolate
