Improvement in Lung Function and Patient-Reported Outcomes in Patients with COPD with Comorbid Anxiety and Depression Receiving Nebulized Glycopyrrolate in the GOLDEN 3 and 4 Studies

Abstract

Background: Anxiety and depression (A/D) are common in patients with chronic obstructive pulmonary disease (COPD) and are often associated with lower adherence to treatment and worse patient-related outcomes. 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 (FEV 1 ) 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 FEV 1 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 FEV 1 , 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.

Impact of COVID-19, cancer survivorship and patient-provider communication on mental health in the US Difference-In-Difference

“…Last, those who had chronic lung disease were more likely to have poor mental health, a finding that has been reported previously and is likely related to the poor quality of life among those with chronic lung disease 60 , 61 . Similarly, we also observed that those with poor general health status were more likely to have poor mental health, which is consistent with a previous report that considered depression and anxiety among cancer survivors 25 .…”
