Received 7 July Published 30 December Volume Peer reviewers approved by Dr Lucy Goodman. Editor who approved publication: Studies of these FDCs have demonstrated substantial improvements in lung function forced expiratory volume in 1 second in comparison with their respective constituent monocomponents.

Improvements in patient-reported outcomes PROssuch as symptoms and health status, as well as exacerbation rates, have been reported compared with a LABA or LAMA alone, but results are less consistent.

JOURNAL MENU

The inconsistencies may in part be owing to differences in study design, methods used to assess study end points, and patient populations.

Nevertheless, these observations tend to support an association between improvements in forced expiratory volume in 1 second and improvements in symptom-based outcomes.

In order to assess the effects of FDCs on PROs and evaluate relationships between PROs and changes in lung function, we performed a systematic literature search of publications reporting randomized controlled trials of FDCs. Results of this literature search were independently assessed by two reviewers, with a third reviewer resolving any conflicting results. In total, 22 Phase III randomized controlled trials of FDC bronchodilators in COPD were identified, with an additional study including a post-literature search ten for indacaterol—glycopyrronium once daily, eight for umeclidinium—vilanterol once daily, three for tiotropium—olodaterol once daily, and two for aclidinium—formoterol twice daily.

Overall, the safety profiles of the FDCs were similar to placebo.

Appropriate pharmacological management of COPD involves treatment with inhaled bronchodilators to reduce airflow limitation and hyperinflation. Beta agonists BAs and muscarinic antagonists MAs target different pathways to promote smooth-muscle relaxation and inhibit pulmonary constriction. Click bronchodilators with different modes of action see more to be additive, providing greater efficacy versus component monotherapies.

COPD is characterized by persistent airflow limitation, with forced expiratory volume in 1 second FEV 1 to forced vital capacity ratio and percentage predicted FEV 1 widely used as pathophysiological markers. Outcomes in addition to FEV 1 are needed to assess disease burden and treatment efficacy. Data sources included a ProQuest search of Biosis, Biosis previews, Embase and Medline databases January 1, to July 31,and abstracts from principal respiratory congresses January 1, to May 20, ; Table S2.

These selected search dates ensured that all relevant publications on fixed-combination bronchodilators were captured. Following the publication-database searches and during preparation of this manuscript August onwardadditional relevant articles became available, and thus these were added to the literature-search results. All search results were extracted and gathered by a single party. Conflicting results were resolved by a third reviewer, who provided input as to whether the abstract was of potential relevance based on the same criteria as the first reviewers.

The searches yielded records, from 2018 Guidelines For Copd Management Flowchart Symbols Communication 35 primary publications were relevant Figure 1. Literature searches were supplemented with information from ClinicalTrials. Figure 1 Flowchart of systematic literature search. Reasons for exclusion comprised: Treatment was once daily unless stated otherwise. Findings from 12 Phase III trials had been reported in publications or conference abstracts at the time of the literature search, including: Findings from two of four Phase III trials have been fully reported comparing the combination therapy versus monocomponents or placebo, and are included in this paper Table 1.

In this review, we focus on the 23 aforementioned published Phase III RCTs and listed in Table 1 supplemented with results presented at major respiratory congresses, where applicable: The remaining primary publications from the literature search were excluded, due to duplicate publications of the same results eg, where a primary publication superseded several congress abstracts. Patient populations, inclusion criteria, treatment blinding, and other characteristics differed between trials Table 1.

The majority of indacaterol—glycopyrronium OD studies enrolled symptomatic patients with moderate-to-severe airflow limitation GOLD, or classificationexcept for SPARK and FLAME, which enrolled patients with severe-to-very-severe or moderate-to-very-severe disease, respectively, and one or more exacerbations in the past year. Table 2 Lung function: Treatment once daily unless stated otherwise. Table 3Figure 2.

The data available from analysis of secondary end points indicate that umeclidinium—vilanterol significantly increased time to first exacerbation versus placebo HR 0. Citing abstracts is highly discouraged. When applicable, statements regarding Ethics Committee and Institutional Review Board approval, written informed consent and clinical trial registration must be included in this section.

Figure 2 Differences between monotherapy and combination bronchodilators or placebo in TDI patient-response rates in published studies. A Indacaterol—glycopyrronium; B umeclidinium—vilanterol All treatments were once daily unless stated otherwise. Three indacaterol—glycopyrronium OD studies evaluated patient-diary data and reported significantly improved symptom scores versus indacaterol, glycopyrronium, tiotropium, or placebo Table 3.

In three week studies, umeclidinium—vilanterol In two week studies, there was no significant difference in TDI focal scores between umeclidinium—vilanterol Symptoms were evaluated using a number of end points in the two week aclidinium—formoterol BID studies.

For Evaluating Respiratory Symptoms E-RS score, the combination was significantly better than placebo both studies and the monotherapies one study. Rescue-medication usage provides a surrogate measure of symptom control, and was reported in most of the published indacaterol—glycopyrronium OD and umeclidinium—vilanterol OD Phase III trials Table 4.

Table 4 Rescue-medication use: Statistical analysis not reported. The effects of FDC therapy on exacerbation rates and time to first exacerbation are summarized in Table 5. Currently, there are no studies evaluating exacerbation risk as a primary end point in patients receiving umeclidinium—vilanterol OD.

Individuals who provided paid contributions to the paper including writers, statisticians, epidemiologists, and any others involved with data management and analyses may meet the criteria for authorship. The Editor may send the revision for peer review and further revision may be requested. Findings from 12 Phase III trials had been reported in publications or conference abstracts at the time of the literature search, including: In two week studies, there was no significant difference in TDI focal scores between umeclidinium—vilanterol Statistical Methods and Hypothesis Where appropriate, all original articles should state the hypothesis that is being tested and detail the statistical method that was used.

The data available from analysis of secondary end points indicate that umeclidinium—vilanterol significantly increased time to first exacerbation versus placebo HR 0. Time to first exacerbation was comparable for combination therapy versus tiotropium alone in two trials 23 and significantly greater in a third study HR 0.

Table 6 Health status: Proportions of SGRQ responders were significantly increased for all the combination-versus-component comparisons, apart from tiotropium—olodaterol 2. To date, the most extensive safety data available for FDC bronchodilators comes from indacaterol—glycopyrronium 2018 Guidelines For Copd Management Flowchart Symbols Communication trials.

Overall, indacaterol—glycopyrronium was well tolerated across the studies, and had a similar safety profile to placebo in individual trials and analyses of pooled data. Over 24 weeks, umeclidinium—vilanterol As the imbalances were not dose-related, they were not considered drug-related. The incidence of cardiovascular AEs of special interest was comparable for umeclidinium—vilanterol, monocomponents, and placebo.

In the two 1-year tiotropium—olodaterol OD studies, the frequency of AEs was largely comparable between the combination- and individual component-treatment groups. The rates of MACE and cardiac events did not read article significantly between the combination and the individual component groups.

The data demonstrated that fixed-dose LAMA—LABA combinations significantly improved lung function compared with component monotherapies or single agents. However, although significant or clinically relevant correlations appear at group levels, they tend to be only moderate, weak, or too weak to be useful at individual levels. Likewise, in trials of combination-bronchodilator therapy versus components, improvement in FEV 1 was not 2018 Guidelines For Copd Management Flowchart Symbols Communication mirrored by improved PROs.

For example, significant improvement in dyspnea for umeclidinium—vilanterol OD versus monocomponents occurred only for vilanterol in one of three trialsdespite improvements in FEV 1.

Findings may still be somewhat limited though, as these end points are often only secondary, meaning power may be lacking. Patient-selection criteria represent an important limitation of RCTs.

As such, the extrapolation of RCT data is limited. Clinical trial participants tend to be less symptomatic than general patient populations, and clinical trials may exclude patients likely to benefit the most from 2018 Guidelines For Copd Management Flowchart Symbols Communication as a maximum level of benefit may be reached sooner.

Additionally, the most symptomatic patients in control arms may discontinue study treatment to obtain greater symptom relief. In contrast, real-life studies are likely to involve broader populations and treat each study arm to a similar level. Roche et al suggested a new framework to categorize the approach taken in clinical trials from highly controlled efficacy RCT management to usual clinical care. In addition, composite end points, such as lack of exacerbations and improved health status, may provide greater insight into the true benefits of treatment.

Additional studies of fixed-combination bronchodilators are needed to characterize further the relationship between FEV 1 and PROs with these agents, as well as defining optimal strategies for their use in clinical practice. In conclusion, our review of a systematic literature search indicates that fixed-dose LABA—LAMA combinations significantly improved lung function compared with their component monotherapies.

In general, LABA—LAMA combinations also improved other outcomes, including symptoms and health status, compared with the monotherapies, although some discrepancies between lung function and PROs were apparent. All authors contributed to the concept and objectives of the review and provided guidance on the literature search, presentation, and discussion of the findings, as well as critically reviewing the article.
