Meta Analysis Comparative StudyImpact of ICS/LABA and LABA/LAMA FDCs on functional and clinical outcomes in COPD: A network meta-analysis.
Inhaled corticosteroid (ICS)/long-acting β2 agonist (LABA) fixed-dose combinations (FDCs) and LABA/long-acting muscarinic antagonist (LAMA) FDCs are extensively used to treat chronic obstructive pulmonary disease (COPD). The aim of the present network meta-analysis was to assess the comparative efficacy of all the currently available dual therapies in patients with moderate-to-severe COPD. ⋯ The results of this meta-analysis show that LABA/LAMA combinations are consistently more effective than ICS/LABA FDCs for most of the evaluated outcomes. However, differences have also been observed between FDCs belonging to the same class. Across the investigated LABA/LAMA FDCs, glycopyrronium/indacaterol revealed a consistent and robust efficacy profile.

Meta Analysis Comparative StudyEfficacy and cardiovascular safety profile of dual bronchodilation therapy in chronic obstructive pulmonary disease: A bidimensional comparative analysis across fixed-dose combinations.
Despite several long-acting β2-adrenoceptor agonist (LABA)/long-acting muscarinic antagonist (LAMA) fixed-dose combinations (FDCs) are currently approved for the treatment of chronic obstructive pulmonary disease (COPD), there are limited findings concerning the direct comparison across the different LABA/LAMA FDCs. The aim of this study was to compare the efficacy/safety profile of approved LABA/LAMA FDCs in COPD. A network meta-analysis was performed by linking the efficacy (forced expiratory volume in 1 s, St' George Respiratory Questionnaire, transitional dyspnea index) and safety (cardiovascular serious adverse events) outcomes resulting from randomized controlled trials that directly compared LABA/LAMA FDCs with placebo and/or each other. ⋯ The IBiS score showed the following rank of efficacy/safety profile: tiotropium/olodaterol 5/5 μg (area 66.83%) » glycopyrronium/indacaterol 15.6/27.5 μg (area 40.43%) > umeclidinium/vilanterol 62.5/25 μg (area 30.48%) ≈ aclidinium/formoterol 400/12 μg (area 28.44%) > glycopyrronium/indacaterol 50/110 μg (area 19.95%) > glycopyrronium/formoterol 14.4/9.6 μg (area 11.50%). Each available LABA/LAMA FDC has a specific efficacy/safety profile that needs to be considered for personalized therapy in COPD. Head-to-head studies aimed to assess the impact of different LABA/LAMA FDCs on the risk of COPD exacerbation are needed to further improve the information provided by this quantitative synthesis.
