Indacaterol/glycopyrronium in symptomatic patients with COPD (GOLD B and GOLD D) versus salmeterol/fluticasone: ILLUMINATE/LANTERN pooled analysis.

BACKGROUND

Indacaterol/glycopyrronium (IND/GLY) is approved for maintenance treatment of adult patients with COPD. This post hoc analysis explored the efficacy and safety of IND/GLY versus salmeterol/fluticasone (SFC) in symptomatic (Global Initiative for Chronic Obstructive Lung Disease [GOLD] B and GOLD D) patients with moderate-to-severe COPD.

PATIENTS AND METHODS

Data from LANTERN and ILLUMINATE studies were pooled and analyzed. In both studies, symptomatic COPD patients were randomized to once-daily IND/GLY 110 μg/50 μg or twice-daily SFC 50 μg/500 μg. End points were pre-dose trough forced expiratory volume in one second (FEV), standardized area under the curve for FEV from 0 to 12 hours (FEV AUC hours), peak FEV, peak forced vital capacity (FVC), pre-dose trough FVC, Transition Dyspnea Index (TDI) total score, St George's Respiratory Questionnaire total score, rescue medication use and safety.

RESULTS

A total of 1,263 patients were classified as either GOLD B (n=809) or GOLD D (n=454). At week 26, IND/GLY demonstrated statistically significant improvement in all lung function parameters versus SFC in patients in both the GOLD B and GOLD D subgroups. TDI total score and rescue medication use were significantly improved with IND/GLY versus SFC in the overall population and in the GOLD B (TDI total score only) and GOLD D (rescue medication only) subgroups. IND/GLY also reduced the rate of exacerbations in the pooled population. Overall safety profile was comparable with a higher incidence of pneumonia in the SFC-treated group.

CONCLUSION

In this pooled analysis, IND/GLY demonstrated superior efficacy compared with SFC in patients in the GOLD B and GOLD D subgroups and supported its use in symptomatic COPD patients.
