The Effect of Baseline Rescue Medication Use on Efficacy and Safety of Nebulized Glycopyrrolate Treatment in Patients with COPD from the GOLDEN 3 and 4 Studies.

ABSTRACT: Purpose:Rescue medication use is common in chronic obstructive pulmonary disease (COPD) patients and tends to increase with symptoms and disease severity. An analysis of baseline rescue medication use was conducted to inform on patient phenotypes and subsequent effects on lung function, symptoms, and safety following 12 weeks of nebulized glycopyrrolate (GLY) 25 µg twice daily or placebo in patients with moderate-to-very-severe COPD. Patients and Methods:Pooled data from the 12-week, placebo-controlled GOLDEN 3 and 4 studies (n=781) were used to assign patients into quarters based on baseline rescue medication use (ie, average puffs-per-day) during the run-in period. Placebo-adjusted trough forced expiratory volume in 1 second (FEV1), St. George's Respiratory Questionnaire (SGRQ) total score and EXAcerbations of COPD Tool-Respiratory Symptoms (EXACT-RS) total score data were reported; safety was evaluated by reviewing the incidence of adverse events (AEs) and serious AEs (SAEs). Results:Baseline rescue medication use was a proxy for disease severity, evidenced by decreased lung function, increased health status scores, symptom scores and use of background long-acting ?2-agonists and inhaled corticosteroids across quarters and treatment groups. Treatment with GLY led to greater improvements from baseline in trough FEV1, SGRQ and EXACT-RS scores compared with placebo in all rescue medication use quarters. Additionally, the SGRQ and EXACT-RS exhibited greater improvement with increased baseline rescue medication use with GLY treatment. In the Q4 patients, SGRQ (?4-unit reduction) or EXACT-RS (?2-unit reduction) responders were significantly greater with GLY compared with placebo. AE and SAE incidences were similar across quartiles. Conclusion:These results suggest that baseline rescue medication use assessments may be useful in the management of COPD. Treatment with nebulized GLY improved lung function and symptom scores, regardless of baseline rescue medication use. These results support the use of nebulized GLY for the treatment of COPD, independent of baseline rescue medication use.

Project description:IntroductionLung hyperinflation in chronic obstructive pulmonary disease (COPD) is associated with activity limitation, impaired cardiac output, and mortality. Several studies have demonstrated that long-acting muscarinic antagonists (LAMAs) delivered by dry powder inhalers can promote lung deflation; however, the potential of nebulized LAMAs on improving hyperinflation in COPD is currently unknown.MethodsThis single-center, randomized, double-blind, two-way crossover study (NCT04155047) evaluated the efficacy of a single dose of nebulized LAMA [glycopyrrolate (GLY) 25 µg] versus placebo in patients with COPD and lung hyperinflation. Patients with moderate-to-severe COPD and a residual volume (RV) ≥ 130% of predicted normal were included. The primary endpoint was changed from baseline in RV at 6 h post-treatment. Other endpoints included changes from baseline in spirometric and plethysmographic measures up to 6 h post-treatment.ResultsA total of 22 patients (mean pre-bronchodilator RV, 153.7% of predicted normal) were included. The primary objective of the study was not met; the placebo-adjusted least squares (LS) mean [95% confidence interval (CI) change from baseline in RV with GLY at 6 h post-treatment was - 0.323 l (- 0.711 to 0.066); p = 0.0987]. A post hoc evaluation of the primary analysis was conducted after excluding a single statistical outlier; substantial improvements in RV with GLY compared with placebo was observed after exclusion of this outlier [placebo-adjusted LS mean change from baseline (95% CI) in RV was - 0.446 l (- 0.741 to - 0.150)]. Improvements from baseline were also observed with GLY compared with placebo in spirometric and plethysmographic measures up to 6 h post-treatment. GLY was generally safe, and no new safety signals were detected.ConclusionsThis is the first study to evaluate the effect of nebulized GLY on lung deflation. Nebulized GLY resulted in marked improvements in RV up to 6 h post-treatment, compared with placebo. Improvements were also observed with GLY in spirometric and plethysmographic parameters of lung function.Trial registrationClinicalTrials.gov identifier, NCT04155047.

Project description:Long-acting bronchodilators including muscarinic antagonists are central to the management of patients with COPD. The Glycopyrrolate Effect on syMptoms and lung function (GEM2) study assessed the efficacy and safety of twice-daily glycopyrrolate 15.6 ?g in patients with moderate-to-severe airflow limitation. This 12-week multicenter, double-blind study randomized (1:1) patients to glycopyrrolate 15.6 ?g twice daily (b.i.d.) or placebo both delivered via the NeohalerTM device. The primary objective was superiority of glycopyrrolate compared with placebo for forced expiratory volume in 1 second (FEV1) standardized area under curve (AUC) between 0 and 12 hours post dosing (FEV1 AUC0-12h)at week 12. Other outcomes included additional spirometry parameters, health status using St George's Respiratory Questionnaire (SGRQ), dyspnea via Transition Dyspnea Index (TDI), rescue medication use and COPD symptoms reported by patients via the electronic diary. Safety was also assessed. Of the 432 patients randomized (glycopyrrolate, n=216; placebo, n=216), 96% completed the planned treatment phase. The study met its primary objective (superiority of glycopyrrolate compared with placebo for FEV1 AUC0-12h).Compared with placebo, glycopyrrolate showed significant improvements in lung function parameters (p<0.001). Health status (SGRQ total score and COPD assessment test), rescue medication use and daily total COPD symptom scores were significantly improved with glycopyrrolate versus placebo over 12 weeks. Improvements in dyspnea were observed with glycopyrrolate and placebo although the treatment difference was not statistically significant. Overall, differences in the incidences of adverse events and serious adverse events between the groups were not considered clinically meaningful. No deaths were reported. Twice-daily glycopyrrolate 15.6 ?g showed statistically significant and clinically meaningful improvements compared with placebo in lung function, COPD symptoms, health status, and rescue medication usage in COPD patients with moderate-to-severe airflow limitation. CLINICAL TRIAL REGISTRATION:NCT01715298.

Project description:PurposeUsing a composite endpoint, pooled data from two 12-week Phase III placebo-controlled trials (GOLDEN 3, NCT02347761; GOLDEN 4, NCT02347774) were analyzed to determine whether glycopyrrolate inhalation solution (25 mcg and 50 mcg) administered twice daily (BID) via the eFlow® Closed System nebulizer (GLY) reduced the risk of clinically important deterioration (CID) in patients with moderate-to-very-severe COPD.MethodsCID was defined as ≥100-mL decrease from baseline in post-bronchodilator trough forced expiratory volume in one second (FEV1), or ≥4-unit increase in baseline St. George's Respiratory Questionnaire (SGRQ) total score, or moderate/severe exacerbation. The relative treatment effect of GLY versus placebo on the odds of CID (any and by component endpoints) was expressed as the odds ratio (OR) and 95% confidence interval (CI). Subgroups categorized by age (<65/≥65 years), sex, smoking status (current/former), long-acting beta agonist (LABA) use, FEV1 (<50%/≥50%), and peak inspiratory flow rate (PIFR) (<60 L/min/≥60 L/min) were analyzed.ResultsCompared to placebo, GLY 25 mcg and 50 mcg BID over 12 weeks significantly reduced the risk of CID by 50% (OR: 0.50 [0.37-0.68]) and 40% (OR: 0.60 [0.44-0.80]), respectively. Subjects treated with GLY 25 mcg BID were 59% less likely to experience CID in FEV1 (OR: 0.41 [0.27-0.62]) and 48% less likely to perceive CID in health status (OR: 0.52 [0.37-0.73]). Statistically significant reductions were also observed at the higher dose. The incidence of moderate/severe exacerbations was low and comparable among the cohorts. GLY 25 mcg BID was significantly more effective than placebo (p<0.05) in preventing CID irrespective of age, smoking status, LABA use, COPD severity, or PIFR. Subjects <65 years (OR 0.45 [0.29-0.68]) and those with PIFR <60 L/min (OR 0.36 [0.20-0.67]) exhibited the largest benefit.ConclusionNebulized GLY over 12 weeks significantly reduced the risk of CID and provided greater short-term stability in patients with moderate-to-very-severe COPD.
