<h4>Background</h4>Three classes of inhaler medication are used to manage chronic obstructive pulmonary disease (COPD): long-acting beta₂-agonists (LABA); long-acting muscarinic antagonists (LAMA); and inhaled corticosteroids (ICS). To encourage patient adherence, two classes of medication are often combined in a single medication device; it seems that once-daily dosing offers greatest convenience to patients and may markedly influence adherence.<h4>Objectives</h4>To compare a once-daily combina ...[more]

Project description:Importance:Long-acting muscarinic antagonists (LAMAs) are a potential adjunct therapy to inhaled corticosteroids in the management of persistent asthma. Objective:To conduct a systematic review and meta-analysis of the effects associated with LAMA vs placebo or vs other controllers as an add-on therapy to inhaled corticosteroids and the use of a LAMA as add-on therapy to inhaled corticosteroids and long-acting β-agonists (LABAs; hereafter referred to as triple therapy) vs inhaled corticosteroids and LABA in patients with uncontrolled, persistent asthma. Data Sources:MEDLINE, EMBASE, Cochrane databases, and clinical trial registries (earliest date through November 28, 2017). Study Selection:Two reviewers selected randomized clinical trials or observational studies evaluating a LAMA vs placebo or vs another controller as an add-on therapy to inhaled corticosteroids or triple therapy vs inhaled corticosteroids and LABA in patients with uncontrolled, persistent asthma reporting on an outcome of interest. Data Extraction and Synthesis:Meta-analyses using a random-effects model was conducted to calculate risk ratios (RRs), risk differences (RDs), and mean differences (MDs) with corresponding 95% CIs. Citation screening, data abstraction, risk assessment, and strength-of-evidence grading were completed by 2 independent reviewers. Main Outcomes and Measures:Asthma exacerbations. Results:Of 1326 records identified, 15 randomized clinical trials (N = 7122 patients) were included. Most trials assessed adding LAMA vs placebo or LAMA vs LABA to inhaled corticosteroids. Adding LAMA vs placebo to inhaled corticosteroids was associated with a significantly reduced risk of exacerbation requiring systemic corticosteroids (RR, 0.67 [95% CI, 0.48 to 0.92]; RD, -0.02 [95% CI, -0.04 to 0.00]). Compared with adding LABA, adding LAMA to inhaled corticosteroids was not associated with significant improvements in exacerbation risk (RR, 0.87 [95% CI, 0.53 to 1.42]; RD, 0.00 [95% CI, -0.02 to 0.02]), or any other outcomes of interest. Triple therapy was not significantly associated with improved exacerbation risk vs inhaled corticosteroids and LABA (RR, 0.84 [95% CI, 0.57 to 1.22]; RD, -0.01 [95% CI, -0.08 to 0.07]). Conclusions and Relevance:In this systematic review and meta-analysis, the use of LAMA compared with placebo as add-on therapy to inhaled corticosteroids was associated with a lower risk of asthma exacerbations; however, the association of LAMA with benefit may not be greater than that with LABA. Triple therapy was not associated with a lower risk of exacerbations.

Project description:BackgroundA number of long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) fixed-dose combinations (FDCs) for treatment of moderate-to-very severe chronic obstructive pulmonary disease (COPD) have recently become available, but none have been directly compared in head-to-head randomized controlled trials (RCTs). The purpose of this study was to assess the relative clinical benefit of all currently available LAMA/LABA FDCs using a Bayesian network meta-analysis (NMA).MethodsA systematic literature review identified RCTs investigating the efficacy, safety and quality of life associated with licensed LAMA/LABA FDCs for the treatment of moderate-to-very severe COPD. RCTs were screened for inclusion in the NMA using prespecified eligibility criteria. Data were extracted for outcomes of interest, including change in trough forced expiratory volume in 1 second (tFEV1) from baseline, St. George Respiratory Questionnaire (SGRQ) percentage of responders, Transition Dyspnea Index (TDI) percentage of responders, change in SGRQ score from baseline, change in TDI focal score from baseline, moderate-to-severe exacerbations, all-cause discontinuation, and discontinuation due to adverse events.ResultsFollowing screening, a total of 27 trials from 26 publications with 30,361 subjects were eligible for inclusion in the NMA. Nonsignificant results were seen in most analyses comparing efficacy, exacerbations and discontinuation rates of included LAMA/LABA FDCs (i.e. aclidinium/formoterol 400/12 µg, glycopyrronium/indacaterol 110/50 µg, tiotropium + olodaterol 5/5 µg, umeclidinium/vilanterol 62.5/25 µg). Meta-regression controlling for post-bronchodilator percentage of tFEV1 predicted at baseline as well as meta-regression adjusting for concomitant use of inhaled corticosteroids at baseline was performed to assess the magnitude of effect modification and produced similar results as observed in the base case analysis.ConclusionAll LAMA/LABA FDCs were found to have similar efficacy and safety. Definitive assessment of the relative efficacy of different treatments can only be performed through direct comparison in head-to-head RCTs. In the absence of such data, this indirect comparison may be of value in clinical and health economic decision-making.
