BACKGROUND: Several new fixed-dose combination bronchodilators have been recently launched, and assessing their efficacy relative to each other, and with open dual combinations is desirable. This network meta-analysis (NMA) assessed the efficacy of umeclidinium and vilanterol (UMEC/VI) with that of available dual bronchodilators in single/separate inhalers.
METHODS: A systematic literature review identified randomized controlled trials of ≥10 weeks among chronic obstructive pulmonary disease patients (≥40 years), assessing the efficacy of combination bronchodilators in single or separate inhalers. Comparative assessment was conducted on change from baseline in trough forced expiratory volume in 1 second (FEV1), St George's Respiratory Questionnaire (SGRQ) total scores, transitional dyspnea index (TDI) focal scores, and rescue medication use at 12 weeks and 24 weeks using an NMA within a Bayesian framework.
RESULTS: A systematic literature review identified 77 articles of 26 trials comparing UMEC/VI, indacaterol/glycopyrronium (QVA149), formoterol plus tiotropium (TIO) 18 μg, salmeterol plus TIO, or indacaterol plus TIO, with TIO and placebo as common comparators at 12 weeks and approximately 24 weeks. The NMA showed that at 24 weeks, efficacy of UMEC/VI was not significantly different compared with QVA149 on trough FEV1 (14.1 mL [95% credible interval: -14.2, 42.3]), SGRQ total score (0.18 [-1.28, 1.63]), TDI focal score (-0.30 [-0.73, 0.13]), and rescue medication use (0.02 [-0.27, 0.32]); compared with salmeterol plus TIO on trough FEV1 (67.4 mL [-25.3, 159.4]), SGRQ total score (-0.11 [-1.84, 1.61]), and TDI focal score (0.58 [-0.33, 1.50]); and compared with formoterol plus TIO 18 μg on SGRQ total score (-0.68 [-1.77, 0.39]). Results at week 12 were consistent with week 24 outcomes. Due to lack of availability of evidence, no comparison was made with formoterol plus TIO on FEV1 or TDI at 24 weeks.
CONCLUSION: UMEC/VI has comparable efficacy to other dual-bronchodilator combinations on available efficacy endpoints.
