PURPOSE: Long-acting bronchodilators including muscarinic antagonists are central to the management of symptoms in patients with COPD. Glycopyrronium (GLY) 50 µg q.d. is approved for maintenance bronchodilator treatment in patients with COPD in more than 80 countries including countries within the EU and Japan, Canada, Switzerland and Australia. Here, we present the results of patient reported outcomes from the pooled analysis of GEM1 and GEM2 studies.

METHODS: GEM1 and GEM2 were 12-week, multicenter, double-blind, placebo-controlled, replicate studies, designed to assess efficacy and safety of GLY 12.5 µg b.i.d compared with placebo (both delivered via the NeohalerTM device). Change in health status, dyspnea, and rescue medication use were measured by St. George’s Respiratory Questionnaire [SGRQ] total score, Transition Dyspnea Index [TDI] focal score, and puffs/day of rescue medication, respectively.

RESULTS: Data from 867 patients from the GEM1 and GEM2 studies (GLY, n=437, placebo, n=430) were included in this analysis. Baseline patient demographics were comparable between the two treatment groups. At week 12, compared with placebo, GLY showed a significant reduction in the SGRQ total score [Least Square Mean treatment difference (LSMTD) (95% CI): -4.0 units (-5.6, -2.3), p<0.001] which reached the minimal clinically important difference (MCID) of ≥4 units decrease in SGRQ total score from baseline. GLY also showed a significant improvement in TDI focal score [LSMTD (95% CI): 0.70 units (0.28, 1.12); p=0.001] at week 12 compared with placebo. The proportion of patients achieving the MCID for the SGRQ total score (≥4 units decrease) and TDI focal score (≥1 unit) at week 12 were significantly higher with GLY compared with placebo (SGRQ: GLY, 52%, placebo, 42%, Odds ratio (95%CI) 1.59 (1.19,2.12), p=0.002; TDI: GLY, 54%; placebo, 41%, Odds ratio (95%CI), 1.75 (1.30, 2.36), p<0.001]. The change from baseline in rescue medication use over 12 weeks was significantly lower with GLY compared with placebo [LSMTD (95% CI): -0.66 puffs/day (-0.97, -0.36); p<0.001].

CONCLUSIONS: In COPD patients with moderate-to-severe airflow limitation, treatment with glycopyrronium 12.5 µg b.i.d. improves health status and dyspnea, and reduces rescue medication usage.

CLINICAL IMPLICATIONS: Glycopyrronium 12.5 µg twice daily can be an effective treatment option to reduce COPD symptoms and improve quality of life in patients with COPD with moderate-to-severe airflow limitation.
