Efficacy and safety of once-daily single-inhaler triple therapy for mild-to-moderate chronic obstructive pulmonary disease: a study protocol for a randomised and interventional study.

INTRODUCTION: Bronchodilators, including long-acting muscarinic antagonists (LAMA) and long-acting beta 2 agonists (LABA), are the main treatments for chronic obstructive pulmonary disease (COPD). The efficacy of triple therapy (inhaled corticosteroids/LAMA/LABA) has also been reported. However, the effect of triple therapy on patients with mild-to-moderate COPD has not yet been clarified. This study aims to investigate the safety and efficacy of triple therapy, compared with LAMA/LABA combination therapy, for lung function and health-related quality of life in patients with mild-to-moderate COPD and identify baseline characteristics and biomarkers to predict responders and non-responders to triple therapy. METHODS AND ANALYSIS: This is a multicentre, prospective, open-label, randomised, parallel-group study. Mild-to-moderate patients with COPD will be randomised to receive fluticasone furoate/umeclidinium/vilanterol or umeclidinium/vilanterol for 24 weeks. A total of 668 patients will be enrolled from March 2022 to September 2023 from 38 sites in Japan. The primary endpoint is the change in the trough forced expiration volume in 1 s after 12 weeks of treatment. Secondary endpoints are responder rates based on the COPD assessment test score and the St. George's Respiratory Questionnaire total score after 24 weeks of treatment. The safety endpoint is the occurrence of any adverse events. We will also investigate safety in terms of changes in microbial colonisation in sputum and antimycobacterium avium complex antibodies. ETHICS AND DISSEMINATION: The study protocol and informed consent documents were approved by the Saga University Clinical Research Review Board (approval number: CRB7180010). Written informed consent will be obtained from all patients. Recruitment of the patients began in March 2022. The results will be disseminated through scientific peer-reviewed publications and domestic and international medical conferences. TRIAL REGISTRATION NUMBERS: UMIN000046812 and jRCTs031190008.

Open-inhaler versus single-inhaler triple therapy (long-acting muscarinic antagonist, inhaled corticosteroid, and long-acting ß2-agonist) in asthma patients: a narrative review.

OBJECTIVE: To review the evidence for the use of open-inhaler (inhaled corticosteroid [ICS] plus long-acting ß2-agonist [LABA] with separate add-on long-acting muscarinic antagonist [LAMA]) versus single-inhaler triple therapy (ICS/LABA/LAMA combination) and the merits of add-on LAMA to ICS/LABA in patients with uncontrolled asthma. DATA SOURCES: Original research articles were identified from PubMed using the search term "triple therapy asthma." Information was also retrieved from the ClinicalTrials.gov website. STUDY SELECTIONS: Articles detailing the use of add-on LAMA to ICS plus LABA (open-inhaler triple therapy), and closed triple therapy compared with ICS plus LABA dual therapy, addressing patient symptoms, exacerbations, and health-related quality of life. RESULTS: Open-inhaler triple therapy was associated with a significantly reduced incidence of hospitalizations and emergency department visits and a decrease in ICS dose, oral corticosteroids use, and antibiotics use. Exacerbations and acute respiratory events were also reduced. Single-inhaler triple therapy showed a greater improvement in lung function, asthma control, and health status and was noninferior to open-inhaler triple therapy for Asthma Quality of Life Questionnaire scores. Single-inhaler triple therapy may also lead to improved therapy adherence. CONCLUSION: Add-on LAMA to ICS plus LABA (open- or single-inhaler triple therapy) improves the response in patients who remain symptomatic and provides a reasonable alternative to ICS dose escalation in treatment-refractory patients.

Combination therapy with long-acting bronchodilators and the risk of major adverse cardiovascular events in patients with COPD: a systematic review and meta-analysis.

INTRODUCTION: Accumulated high-quality data from randomised controlled trials (RCTs) indicate that long-acting muscarinic antagonist (LAMA)/long-acting ß2 agonist (LABA) combination therapy significantly improves clinical symptoms and health status in patients with chronic obstructive pulmonary disease (COPD) and reduces exacerbation risk. However, there is a growing concern that LAMA/LABA therapy may increase the risk of cardiovascular disease in patients with COPD. The aim of this paper is to determine whether the use of LAMA/LABA combination therapy modifies the risk of cardiovascular disease in patients with COPD. METHODS: Two reviewers independently searched Embase, PubMed and Cochrane Library to identify relevant RCTs of LAMA/LABA or LABA/LAMA/inhaled corticosteroids (ICS) for the management of patients with COPD that reported on cardiovascular end-points. The primary outcome was major adverse cardiovascular events (MACE), which was a composite of cardiovascular death, myocardial infarction or stroke. RESULTS: A total of 51 RCTs enrolling 91 021 subjects were analysed. Both dual LAMA/LABA (1.6% versus 1.3%; relative risk 1.42, 95% CI 1.11-1.81) and triple therapy (1.6% versus 1.4%; relative risk 1.29, 95% CI 1.03-1.61) significantly increased the risk of MACE compared with ICS/LABA. The excess risk was most evident in RCTs in which the average underlying baseline risk for MACE was >1% per year. Compared with LAMA only, LABA only or placebo, dual LAMA/LABA therapy did not significantly increase the risk of MACE, though these comparisons may have lacked sufficient statistical power. CONCLUSION: Compared with ICS/LABA, dual LAMA/LABA or triple therapy increases cardiovascular risk in patients with COPD. This should be considered in the context of the incremental benefits of these therapies for symptoms and exacerbation rates in patients with COPD, especially in those with a MACE risk of >1% per year.

The clinical characteristics and outcomes of different inhaled therapies in chronic obstructive pulmonary disease patients with frequent cough.

BACKGROUND: Cough is a common symptom in patients with chronic obstructive pulmonary disease (COPD). Patients with cough may exhibit various clinical characteristics and experience varying outcomes based on inhaled therapies they receive. OBJECTIVES: This study aimed to explore the clinical characteristics and outcomes of various inhaled therapies in COPD patients with frequent cough. METHODS: This was a multicenter, prospective cohort study. Of these patients, the median cough score in COPD assessment test (CAT) was two. Patients were classified into frequent cough group if they scored two or over in the first item of CAT and infrequent cough group otherwise. Patients with frequent cough were then divided into long-acting antimuscarinic (LAMA), long-acting beta2-agonist (LABA)/LAMA, inhaled corticosteroids (ICS)/LABA and ICS/LABA/LAMA groups. Minimum clinically important difference (MCID) (CAT scores decreased ≥2 from baseline) and the improvement of cough (cough score decreased ≥1 from baseline) were collected in the six-month follow-up. Frequent exacerbations (experiencing at least two exacerbations) were collected in the one-year follow-up. RESULTS: Of 906 patients, 581 (64.1%) patients reported frequent cough at the initial visit. Frequent cough was associated with the current smokers and CAT scores (p < 0.05). The MCID showed no significant difference between frequent cough and infrequent cough groups in the follow-up. More patients with frequent cough experienced future frequent exacerbations compared to those with infrequent cough. After receiving inhaled therapies, 62% of patients with frequent cough got the cough improved. More patients with frequent cough treated with LABA/LAMA or ICS/LABA/LAMA attained MCID and fewer experienced exacerbations than those treated with LAMA or ICS/LABA (p < 0.05). The change in cough score showed no difference among various inhaled therapies in patients with frequent cough. CONCLUSION: COPD patients with frequent cough were related to current smokers and higher CAT scores. These patients had a higher incidence of frequent exacerbations than those with infrequent cough. Patients with frequent cough who were treated with LABA/LAMA or ICS/LABA/LAMA were more likely to attain MCID and at a lower risk of exacerbation than those treated with LAMA or ICS/LABA.

Cost-Effectiveness of Triple Therapy with Budesonide/Glycopyrronium/Formoterol Fumarate Dihydrate versus Dual Therapies in Moderate-to-Very Severe Chronic Obstructive Pulmonary Disease: United Kingdom Analysis Using the ETHOS Study.

Background: In the 52-week ETHOS study (NCT02465567), fixed-dose triple therapy with budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF) reduced moderate or severe chronic obstructive pulmonary disease (COPD) exacerbations versus fixed-dose long-acting muscarinic antagonist (LAMA)/long-acting ß2-agonist (LABA) or inhaled corticosteroid (ICS)/LABA dual therapies. Here, ETHOS data were used to estimate the long-term cost-effectiveness of BGF versus LAMA/LABA and ICS/LABA dual therapies in the United Kingdom. Methods: Costs, exacerbations, quality-adjusted life-years (QALYs), and LYs were extrapolated using a Markov model that considered disease severity progression, risk of moderate and severe exacerbations, adverse events, and treatment discontinuation in patients with moderate-to-very severe COPD receiving BGF 320/14.4/10 µg, the LAMA/LABA glycopyrronium/formoterol fumarate dihydrate 14.4/10 µg (GFF), or the ICS/LABA budesonide/formoterol fumarate dihydrate 320/10 µg (BFF). Utilities for COPD severity states were estimated using EuroQol 5-dimension 5-level data from ETHOS. Exacerbation disutilities were sourced from published literature. Healthcare resource utilization was based on ETHOS data, published literature, key external experts' input, and informed assumptions. Unit costs came from the UK National Health Service Schedule of Reference Costs, Unit Costs of Health and Social Care from the Personal Social Services Research Unit, and published literature. A lifetime horizon was considered, with costs, QALYs, and LYs discounted at 3.5% per annum. Results: The incremental cost-utility ratio (ICUR; per QALY gained) was £9901 for BGF versus GFF and £2164 for BGF versus BFF. The probability of treatments being cost-effective at the conventional UK-adopted willingness-to-pay threshold of ICUR <£20,000 was 85.1% for BGF, 14.3% for GFF, and 0.6% for BFF. Conclusion: Based on ETHOS data, BGF was demonstrated to be cost-effective versus LAMA/LABA and ICS/LABA dual therapies at the conventional UK-adopted willingness-to-pay threshold (ICUR <£20,000). The main cost-effectiveness driver for BGF versus LAMA/LABA and ICS/LABA therapies was reduction in rate of exacerbations, which reduced costs and preserved quality of life.

Impact of switching from triple therapy to dual bronchodilation in COPD: the DACCORD 'real world' study.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) guidelines recommend reserving triple therapy of inhaled corticosteroid (ICS), long-acting ß2-agonist (LABA) and long-acting muscarinic antagonist (LAMA) for patients with exacerbations despite dual therapy. However, many patients receive triple therapy without a clear indication. For these patients, it would be useful to know whether ICS can be withdrawn. METHODS: DACCORD was a longitudinal, non-interventional 'real-world' study in three cohorts. This manuscript describes the results of Cohort 3, which recruited patients with COPD who had received triple therapy for ≥ 6 months. Prior to entry, each patient's physician decided to continue triple therapy, or switch to a LABA/LAMA; patients were then followed for 12 months, with exacerbations and COPD Assessment Test (CAT) data recorded every 3 months. The primary endpoint was the time until COPD worsening, defined as the occurrence of a moderate/severe exacerbation or clinically relevant CAT worsening. RESULTS: Of the 1192 patients recruited into the study, 967 completed the end-of-study visit and ≥ 2 of the three interim visits, 292 and 675 receiving LABA/LAMA and triple therapy, respectively. Most baseline demographics were similar between the two groups. A lower proportion of patients in the LABA/LAMA group had COPD worsening than with triple therapy (32.5% vs 55.7% at 12 months), with the time to worsening extended in the LABA/LAMA group (hazard ratio 2.004, p < 0.001). In addition, a significantly lower proportion of patients in the LABA/LAMA group exacerbated (18.5% vs 28.7%; p < 0.001), accompanied by a greater improvement from baseline in CAT total score. Overall, fewer patients in the LABA/LAMA group reported adverse events than in the triple therapy group (12.9% vs 15.1%). CONCLUSIONS: These results suggest that in a real world setting physicians are able to identify patients who can be 'stepped down' from triple therapy to LABA/LAMA. Following step down, there was no overall decline in COPD-indeed, some patients had better outcomes.

Single inhaler triple therapy (SITT) in asthma: Systematic review and practice implications.

A significant number of patients with asthma remain uncontrolled despite treatment with inhaled corticosteroids (ICS) and long-acting ß2 adrenergic bronchodilators (LABA). The addition of long-acting antimuscarinic agents (LAMA) can improve the management of asthma in these patients. Recently, three novel triple therapy (ICS/LABA/LAMA) formulations in a single-inhaler device (SITT) have been investigated in patients with uncontrolled asthma despite ICS/LABA treatment. Here, we review systematically the evidence available to date in relation to SITT in patients with uncontrolled asthma despite ICS-LABA treatment and conclude that SITT is a safe and effective therapeutic alternative in these patients. We also discuss how to position this new therapeutic alternative in their practical clinical management as well as the opportunities and challenges that it may generate for patients, physicians, and payers.

Medium-dose ICS-containing FDCs reduce all-cause mortality in COPD patients: an in-depth analysis of dual and triple therapies.

OBJECTIVES: The recent publication of additional data retrieval for patients missing week 52 vital status in the original analyses of the ETHOS study provides the urgent need of updating previous network meta-analyses (NMA) to produce stronger evidence on mortality in patients receiving dual and triple FDCs according with the level of ICS dose. METHODS: A NMA was performed to compare the effect of ICS/LABA/LAMA, ICS/LABA, and LABA/LAMA FDCs administered via the same inhaler device in COPD patients. The number need to treat (NNT) was also calculated. RESULTS: When considering on-treatment all-cause of death (analyzed patients: 18,864), MD ICS/LABA/LAMA and MD ICS/LABA FDCs significantly reduced the risk of mortality vs. LABA/LAMA FDC (RR 0.59 95%CrI 0.35-0.97 and 0.61 95%CrI 0.38-0.99 respectively, P < 0.05); NNT ranged between 123 and 129. MD ICS/LABA/LAMA FDC also significantly reduced the risk of adjudicated cardiovascular mortality vs. LABA/LAMA FDC (RR 0.44 95%CI 0.19-0.97, P < 0.05). Low-dose (LD) ICS/LABA FDC did not significantly modulate mortality. CONCLUSION: MD ICS/LABA/LAMA and MD ICS/LABA FDCs were effective in reducing on-treatment all-cause of death, with MD ICS/LABA/LAMA FDC being effective also against adjudicated cardiovascular mortality. The protection against mortality was related with the level of ICS dose in the FDCs.

Evaluating a Cox marginal structural model to assess the comparative effectiveness of inhaled corticosteroids versus no inhaled corticosteroid treatment in chronic obstructive pulmonary disease.

PURPOSE: To evaluate the potential of a Cox marginal structural model (MSM) to estimate the time-varying causal inference of a known clinical trial association where the effectiveness of inhaled corticosteroid- (ICS-) versus non-ICS-containing treatments has been compared in patients with chronic obstructive pulmonary disease (COPD). METHODS: This retrospective study from 2006-2016 used linked data from Clinical Practice Research Datalink-GOLD, Hospital Episode Statistics, and Office for National Statistics mortality. A Cox MSM, incorporating a new-user design, was deemed capable of replicating a clinical trial-like pathway. Repeated outcomes for exacerbation events and stabilized weights were used to include time-varying and fixed covariate exposures. RESULTS: Of 45,958 patients, 55% were male; 52% had moderate COPD. ICS-treated patients had a higher incidence of comorbid asthma than non-ICS-treated patients. Adjusted hazard risk ratios for any exacerbation event: ICS and/or long-acting ß2-agonist (LABA) versus long-acting muscarinic antagonist (LAMA), 1.07 (95% confidence interval 1.04-1.10); ICS/LABA versus LABA and/or LAMA, 1.05 (1.00-1.10); ICS and/or LABA and/or LAMA versus LAMA, 1.04 (1.01-1.06); ICS and/or LABA and/or LAMA versus LABA and/or LAMA 1.02 (0.97-1.07). CONCLUSIONS: The Cox MSM was not able to fully demonstrate results consistent with the previously established benefits of ICS-containing treatments seen in clinical trials. Future studies should continue to investigate causal inference methods and their capability to estimate the long-term outcomes of treatment in COPD.

Time-to-first exacerbation, adherence, and medical costs among US patients receiving umeclidinium/vilanterol or tiotropium as initial maintenance therapy for chronic obstructive pulmonary disease: a retrospective cohort study.

BACKGROUND: Adherence to chronic obstructive pulmonary disease (COPD) maintenance medication is important for managing symptoms and exacerbation risk, and is associated with reduced mortality, hospitalizations, and costs. This study compared on-treatment exacerbations, medical costs, and medication adherence in patients with COPD initiating treatment with umeclidinium/vilanterol (UMEC/VI) or tiotropium (TIO). METHODS: This retrospective matched cohort study selected patients from Optum's de-identified Clinformatics Data Mart database who initiated maintenance treatment with UMEC/VI or TIO between 01/01/2014 and 12/31/2017 (index date defined as the first dispensing). Eligible patients were ≥ 40 years of age and had ≥ 12 months continuous health plan coverage pre- and post-index; ≥ 1 medical claim for COPD pre-index or on the index date; no moderate/severe COPD-related exacerbations on the index date; no asthma diagnosis pre- or post-index; no maintenance medication fills containing inhaled corticosteroids, long-acting ß2-agonists, or long-acting muscarinic antagonists pre-index or on the index date; and no fills for both UMEC/VI and TIO on the index date. Outcomes included time-to-first (Kaplan-Meier analysis) and rates of on-treatment COPD-related moderate/severe exacerbations, medication adherence (proportion of days covered [PDC] and proportion of adherent patients [PDC ≥ 0.8]), and COPD-related medical costs per patient per month (PPPM). Propensity score matching was used to adjust for potential confounders. RESULTS: Each cohort included 3929 matched patients. Kaplan-Meier rates of on-treatment COPD-related exacerbations were similar between cohorts (hazard ratio at 12 months; overall: 0.93, moderate: 0.92, severe: 1.07; all p > 0.05). UMEC/VI versus TIO initiators had significantly higher adherence (mean PDC: 0.44 vs 0.37; p < 0.001; proportion with PDC ≥ 0.8: 22.0% vs 16.4%; p< 0.001) and significantly lower mean on-treatment COPD-related total medical costs ($867 vs $1095 PPPM; p = 0.028), driven by lower outpatient visit costs. CONCLUSIONS: These findings provide valuable information for physicians considering UMEC/VI or TIO as initial maintenance therapy options for patients with COPD.

Comparisons of Efficacy and Safety between Triple (Inhaled Corticosteroid/Long-Acting Muscarinic Antagonist/Long-Acting Beta-Agonist) Therapies in Chronic Obstructive Pulmonary Disease: Systematic Review and Bayesian Network Meta-Analysis.

BACKGROUND: Various combinations of inhaled corticosteroid (ICS), long-acting muscarinic antagonist (LAMA), and long-acting beta-agonist (LABA) have been used as triple therapy for stable chronic obstructive pulmonary disease (COPD). OBJECTIVE: Our study was conducted to answer whether there were significant differences among various combinations in efficacy, for reducing exacerbation or mortality, and in safety, for increasing cardiovascular events or pneumonia. METHOD: We searched parallel-group randomized controlled trials (RCTs) comparing ICS/LAMA/LABA with other inhaled drugs in patients with stable COPD for at least 12 weeks in PubMed, EMBASE, the Cochrane Library, and clinical trial registries from inception to December 31, 2019. We conducted a network meta-analysis with Bayesian statistics using a random-effects model with heterogeneous variance structure (PROSPERO, CRD42019126757). RESULTS: Nine different combinations of ICS/LAMA/LABA were identified in 21 RCTs containing 29,892 patients with moderate to very severe COPD. We could not find any significant evidence suggesting a better treatment for reducing total exacerbations or all-cause mortality among ICS/LAMA/LABA combinations. There were also no significant differences in moderate to severe exacerbation, COPD-related mortality, or cardiovascular disease-related mortality among ICS/LAMA/LABA combinations, and the risk of major adverse cardiovascular events was not different. A significantly lower risk of pneumonia was found in fluticasone propionate (FP)/glycopyrrolate/salmeterol (SAL) than FP/tiotropium/SAL {median odds ratio [OR] (95% credible interval [CrI]) = 0 [0-0.72]} and FP/umeclidinium/SAL {median OR (95% Crl) = 0 [0-0.97]}. CONCLUSION: There were no significant differences in clinical outcomes, including acute exacerbation and all-cause mortality among various ICS/LAMA/LABA combinations in patients with moderate to very severe COPD.

Real-World Treatment Patterns of Multiple-Inhaler Triple Therapy Among Patients with Chronic Obstructive Pulmonary Disease in UK General Practice.

INTRODUCTION: Until recently, triple therapy for chronic obstructive pulmonary disease (COPD) has only been available through treatment with multiple inhalers. Evidence on real-world use of multiple-inhaler triple therapy (MITT), including duration of use and treatment patterns, is limited. METHODS: A retrospective, observational study of electronic health records and hospital episodes in patients with COPD initiating MITT between 2013 and 2015 in the UK was performed. This study described patients initiating, treatment persistence and discontinuation, and prior and subsequent COPD treatments. RESULTS: Eligible patients (N=3825) had a mean age of 69.5 years; most were former or current smokers (95%). The majority (86%) initiated MITT with two inhalers and 14% initiated with three inhalers. Mean duration of use was 5.1 (standard deviation: 4.6) months; 24% of patients persisted for 12 months. Patients who had significantly poorer lung function at baseline (12 months prior to initiating MITT) and had experienced significantly more moderate-to-severe acute exacerbation of COPD (AECOPD) and hospitalizations during the baseline period were more likely to persist for 12 months, compared with those who discontinued within 12 months. Most patients stepped down to an inhaled corticosteroid/long-acting ß2-agonist combination (ICS/LABA; 48%) or a long-acting muscarinic antagonist (LAMA; 45%) after discontinuing MITT. CONCLUSION: Initiation of MITT occurred in patients with clinically relevant symptoms and a history of AECOPD. Persistence varied and was most likely linked to disease severity, although more research is required to fully understand why patients discontinue MITT, the subsequent clinical consequences of therapy discontinuation, and the potential impact of newly available single-inhaler triple therapies.

Long-Acting Bronchodilator Use in Chronic Obstructive Pulmonary Disease in Primary Care in New Zealand: A Retrospective Study of Treatment Patterns and Evolution Using the HealthStat Database.

PURPOSE: Long-acting bronchodilator (LABD) use is the mainstay of pharmacologic treatment for chronic obstructive pulmonary disease (COPD). Few studies describe evolving patterns of LABD use in the setting of changing inhaler availability and updated clinical guidelines. METHODS: A retrospective cohort study in New Zealand using the HealthStat general practice database (01/2014 to 04/2018). Eligible patients (aged ≥40 years) had COPD and ≥1 LABD prescription (long-acting muscarinic antagonist [LAMA] and/or long-acting ß2-agonist [LABA]) during the index period (05/2015 to 04/2016). Demographics and clinical characteristics of all LABD users (overall/by treatment) were described at baseline. Patients starting LABD treatment during the index period, termed "new" users, were also described, as was their treatment evolution over 24 months of follow-up. Yearly LABD initiation rates were assessed from 2015 to 2017, covering changes to Pharmaceutical Management Agency criteria and clinical guidelines. RESULTS: Across 2140 eligible patients, the most common index treatments were inhaled corticosteroid (ICS)/LABA (59.0%) and open triple therapy (LAMA+LABA+ICS; 26.7%). ICS/LABA therapy was highest in younger patients, with open triple therapy highest in older patients. Prior yearly exacerbation rates were lowest in those receiving monotherapy (LABA: 0.9/year; LAMA: 1.1/year) versus dual therapy (all 1.4/year) and open triple therapy (2.2/year). Of 312 new LABD users, ICS/LABA was the most common index treatment (69.6%), followed by LAMA monotherapy (16.0%). Continuous use with index treatment was 31.1% at 12 months and 13.5% at 24 months; mean time to treatment change was 175.5 and 244.1 days, respectively. Among patients modifying treatment at 24 months, 23.0% augmented, 7.0% switched, 45.6% re-started, and 24.4% discontinued/stepped down. Among patients initiating LABD each year from 2015 to 2017, LAMA prescription increased (17% to 46%) while ICS prescription remained stable (approximately 20%). CONCLUSION: Predominant use of ICS/LABA (05/2015 to 04/2016) reflects available LABDs and previous restrictions on LAMA use in New Zealand.

Therapeutic Success of Tiotropium/Olodaterol, Measured Using the Clinical COPD Questionnaire (CCQ), in Routine Clinical Practice: A Multinational Non-Interventional Study.

BACKGROUND: The Clinical COPD Questionnaire (CCQ) is a simple patient-reported tool to measure clinical control of chronic obstructive pulmonary disease (COPD). OBJECTIVE: This open-label, single-arm, non-interventional study (NCT03663569) investigated changes in CCQ score during treatment with tiotropium/olodaterol in clinical practice. METHODS: Data were included from consenting COPD patients, enrolled in Bulgaria, Czech Republic, Hungary, Israel, Lithuania, Poland, Romania, Russia, Slovenia, Switzerland and Ukraine, who were receiving a new prescription for tiotropium/olodaterol according to the treating physician in a real-world environment. The primary endpoint was the occurrence of therapeutic success, defined as a 0.4-point decrease in CCQ score after treatment with tiotropium/olodaterol for approximately 6 weeks. RESULTS: Overall, 4819 patients were treated; baseline and Week 6 CCQ scores were available for 4700 patients, mostly classified as Global Initiative for Chronic Obstructive Lung Disease (GOLD) B (51.6%) or D (42.7%). After 6 weeks' treatment, 81.4% (95% confidence interval [95% CI] 80.24-82.49) of patients achieved therapeutic success; mean improvement in overall CCQ score was 1.02 points (95% CI 1.00-1.05). Improved CCQ score was seen in 92.2% of patients (95% CI 91.43-92.98), 2.5% had no change and 5.3% showed a worsening. When stratified by prior treatment, the greatest benefit was seen in treatment-naïve patients, with 85.7% achieving therapeutic success, compared with 79.5% of those pretreated with long-acting ß2-agonist (LABA)/inhaled corticosteroid (ICS) and 74.2% of those pretreated with LABA or long-acting muscarinic antagonist (LAMA) monotherapy. Overall, rescue medication decreased by 1.25 puffs/day (95% CI 1.19-1.31) versus baseline. In total, 29 patients (0.6%) reported drug-related adverse events and 7 patients reported serious adverse events (0.15%). CONCLUSION: In 4700 COPD patients, 6 weeks' treatment with tiotropium/olodaterol, as initial treatment or follow-up to LAMA or LABA monotherapy or LABA/ICS, improved CCQ and decreased rescue medication use. The adverse event profile was consistent with the known safety profile of tiotropium/olodaterol.

Benefit/Risk Profile of Single-Inhaler Triple Therapy in COPD.

Chronic obstructive pulmonary disease (COPD) is associated with major healthcare and socioeconomic burdens. International consortia recommend a personalized approach to treatment and management that aims to reduce both symptom burden and the risk of exacerbations. Recent clinical trials have investigated single-inhaler triple therapy (SITT) with a long-acting muscarinic antagonist (LAMA), long-acting ß2-agonist (LABA), and inhaled corticosteroid (ICS) for patients with symptomatic COPD. Here, we review evidence from randomized controlled trials showing the benefits of SITT and weigh these against the reported risk of pneumonia with ICS use. We highlight the challenges associated with cross-trial comparisons of benefit/risk, discuss blood eosinophils as a marker of ICS responsiveness, and summarize current treatment recommendations and the position of SITT in the management of COPD, including potential advantages in terms of improving patient adherence. Evidence from trials of SITT versus dual therapies in symptomatic patients with moderate to very severe airflow limitation and increased risk of exacerbations shows benefits in lung function and patient-reported outcomes. Moreover, the key benefits reported with SITT are significant reductions in exacerbations and hospitalizations, with data also suggesting reduced all-cause mortality. These benefits outweigh the ICS-class effect of higher incidence of study-reported pneumonia compared with LAMA/LABA. Important differences in trial design, baseline population characteristics, such as exacerbation history, and assessment of outcomes, have significant implications for interpreting data from cross-trial comparisons. Current understanding interprets the blood eosinophil count as a continuum that can help predict response to ICS and has utility alongside other clinical factors to aid treatment decision-making. We conclude that treatment decisions in COPD should be guided by an approach that considers benefit versus risk, with early optimization of treatment essential for maximizing long-term benefits and patient outcomes.

The Impact of Fixed Triple Therapy with Beclometasone/Formoterol/Glycopyrronium on Health Status and Adherence in Chronic Obstructive Pulmonary Disease (COPD) in an Italian Context of Real Life: The TRITRIAL Study Protocol.

BACKGROUND: The fixed triple combination Beclometasone dipropionate/Formoterol fumarate/Glycopyrronium (BDP/FF/G, Trimbow®), an extrafine formulation in a unique pressurized metered dose inhaler, is indicated for the maintenance treatment in adult patients with moderate to severe COPD, not adequately treated by ICS/LABA or LABA/LAMA. Besides the evidence from three randomized controlled trials, the impact of fixed triple therapy has not been extensively evaluated in a real-world population of COPD patients. TRITRIAL (TRIple Therapy in Real life: Impact on Adherence and HeaLth status) is a non-interventional study to assess the effect of BDP/FF/G in a real world setting in Italy. DESIGN: TRITRIAL is a 12-month, multicenter, cohort, prospective, longitudinal observational study. Two follow-up visits will be performed at 6 and 12 months, respectively. The study includes the collection of anamnestic clinical and functional data before the start of BDP/FF/G. The study is built for digital conduction, from signature of the informed consent on a dedicated web platform, to the collection of questionnaires and clinical data on the eCRF. POPULATION: A total of 800 patients with COPD ranging from Global Initiative for Obstructive Lung Disease (GOLD) stages 2 to 4, receiving therapy with BDP/FF/G according to the Summary of Product Characteristics and local clinical practice, will be recruited. All concomitant therapies will be permitted for the duration of the study. EVALUATIONS: The primary endpoint is the change of CAT score at 12 months versus baseline. Secondary endpoints are adherence, health-related quality of life, sleep quality, disease-related outcomes (lung function and COPD exacerbations), device usability, economic resources consumption, and safety. CONCLUSION: TRITRIAL study is expected to give relevant information about effectiveness of BDP/FF/G fixed triple therapy in a real-life setting of patients with COPD, where adherence, usability of inhalers and patient's preference of the device are crucial factors for the success of the therapy.

Evaluating triple ICS/LABA/LAMA therapies for COPD patients: a network meta-analysis of ETHOS, KRONOS, IMPACT, and TRILOGY studies.

OBJECTIVES: In some studies comparing triple with dual combination therapies in COPD there might be a possible effect of inhaler bias resulting from different inhaler devices being used in comparator arms. The aim of this study was a quantitative synthesis by considering the studies that directly compared triple ICS/LABA/LAMA vs. either dual LABA/LAMA or ICS/LABA therapies administered at fixed-dose combination (FDC) via the same inhaler device. METHODS: A network meta-analysis was performed to assess the efficacy/safety impact of triple ICS/LABA/LAMA FDC compared with dual LABA/LAMA and ICS/LBA FDCs administered via the same inhaler device in COPD patients. The treatment ranking was reported via the surface under the cumulative ranking curve analysis (SUCRA). RESULTS: Data obtained from 21,909 COPD patients were extracted from the ETHOS, KRONOS, IMPACT, and TRILOGY studies, the only that fulfilled the strict inclusion criteria of this research. The weighted efficacy/safety profile resulting from SUCRA provided the following ranking in patients with low eosinophil count: ICS/LABA/LAMA>LABA/LAMA≫ICS/LABA; whereas in patients with high eosinophil count the ranking was as follows: ICS/LABA/LAMA>LABA/LAMA>ICS/LABA FDC. CONCLUSION: Triple ICS/LABA/LAMA FDC and dual LABA/LAMA or ICS/LABA FDCs are characterized by specific efficacy/safety profiles in agreement with the level of blood eosinophil count at baseline.

When to Use Initial Triple Therapy in COPD: Adding a LAMA to ICS/LABA by Clinically Important Deterioration Assessment.

Purpose: Triple therapy versus dual therapy for chronic pulmonary obstructive disease (COPD) can reduce symptoms, limit the risk of acute exacerbations (AEs) as well as improve lung function. Currently, studies that feature clinically important deterioration (CID) as a composite endpoint to assess the need for treatment intensification for patients maintained on dual therapy remained to be scarce. Patients and Methods: This study is a retrospective analysis (January 2014 to January 2018) of COPD patients that presented with moderate to severe AEs during the previous year with blood eosinophil counts ≥ 100 cells/µL. The first line of therapy included a combination of inhaled corticosteroid (ICS) and a long-acting ß2 agonist (LABA). Composite CID was used in assessing the response to treatment after 24 weeks of therapy. Results: This study included 110 patients, of which 49 patients reportedly experienced CID. The most common events of CID include a decline in forced expiratory volume in 1 second (FEV1) ≥ 100 mL from baseline (25/49, 51%) and an increase in COPD Assessment Test (CAT) scores ≥ 2 (13/49, 26.5%); many of these patients respond to the addition of a long-acting muscarinic antagonist (LAMA). Seven patients (7/110, 6.3%) experienced moderate to severe exacerbations while undergoing treatment with ICS/LABA. Univariate and multivariate analyses have identified low baseline FEV1 (OR = 0.81, p = 0.004), high CAT score (OR = 1.89, p = 0.004), and the frequency of AE (OR = 19.86, p = 0.021) as independent predictors of CID. A baseline FEV1 of ≤42%, an initial CAT score ≥ 18, and AE ≥ 2 last year were considered the optimal cut-off values, which were identified via receiver operating characteristics (ROC) curve analysis. Conclusion: Triple therapy (ICS/LABAs/LAMAs) may be considered as first-line treatment in patients experiencing more than 2 times moderate to severe AEs of COPD in the previous year and who have blood eosinophil counts ≥100 cells/µL, reduced lung function (FEV1 ≤ 42%), and more symptoms (CAT score ≥ 18).

Healthcare Resource Utilization, Exacerbations, and Readmissions Among Medicare Patients with Chronic Obstructive Pulmonary Disease After Long-Acting Muscarinic Antagonist Therapy Initiation with Soft Mist versus Dry Powder Inhalers.

Background: Chronic obstructive pulmonary disease (COPD) is often managed with inhaled long-acting muscarinic antagonists (LAMAs), yet real-world data on healthcare resource utilization (HRU) by inhaler type are lacking. This study compared HRU after LAMA initiation with a soft mist inhaler (SMI) versus a dry powder inhaler (DPI). Patients and Methods: Inclusion criteria were COPD diagnosis, age ≥40 years, LAMA initiation (index date = first LAMA SMI or DPI claim 9/1/14-6/30/18), and Medicare Advantage enrollment 1 year pre-index (baseline) to ≥30 days post-index (follow-up). Patients were followed to the earliest of discontinuation, switch, disenrollment, 1 year, or study end (7/31/18). Exclusion criteria were asthma, cystic fibrosis, or lung cancer diagnoses, unavailable demographics, multiple index LAMAs, or baseline LAMA use. Cohorts (SMI or DPI) were balanced on baseline characteristics using inverse probability of treatment weighting. Outcomes included per patient per month (PPPM) COPD-related HRU encounters, and exacerbations (defined as moderate [ambulatory visit with corticosteroid or antibiotic within ±7 days] or severe [emergency visit or inpatient admission]); and 30-day readmissions following COPD-related hospitalizations. Results: After weighting, cohorts (SMI [n=5360] and DPI [n=22,880]) were similar in age (72 and 73 years, respectively), gender (both 52% female), and COPD severity score (31.3 and 31.5, respectively). Cohorts had similar counts of follow-up HRU encounters. However, the SMI cohort had fewer (mean ± standard deviation) COPD-related exacerbations (0.054±0.082 vs DPI cohort 0.059±0.088 PPPM, p<0.001) overall. Moreover, the SMI cohort had fewer severe exacerbations (0.030±0.058 vs DPI: 0.034±0.065 PPPM, p<0.001). Hospitalizations among SMI patients had a lower adjusted odds of readmission versus hospitalizations among DPI patients (odds ratio: 0.656, 95% confidence interval= 0.460, 0.937; p=0.020). Conclusion: SMI initiators had significantly fewer COPD-related exacerbations than DPI initiators. In addition, lower odds of readmissions were observed following COPD-related hospitalizations among the SMI cohort, as compared with the DPI cohort.

Randomized controlled trial of triple versus dual inhaler therapy on small airways in smoking asthmatics.

BACKGROUND: Smoking worsens underlying asthma inflammation and also induces resistance to inhaled corticosteroids (ICS). Small airways dysfunction measured by impulse oscillometry (IOS) is associated with worse control. OBJECTIVES: We investigated the effects on small airways of adding long-acting beta-agonist (LABA) alone or with long-acting muscarinic antagonist (LAMA) to ICS in asthmatic smokers. METHODS: Sixteen current smokers were enrolled: mean age 44 year, FEV1 84%, FEF25-75 47%, R5 158%, ACQ 1.69, 20 pack year . Patients were converted to a reference ICS as HFA-BDP during initial run-in at median dose of 800 µg/day. Open label olodaterol 5 µg od (OLO) or olodaterol 5 µg/tiotropium 5 µg od (OLO/TIO) was added to HFA-BDP for median duration of 3 weeks in a randomized cross over design, including run-in and washout periods on HFA-BDP. IOS and spirometry were measured after each treatment (BDP/OLO/TIO or BDP/OLO) and at baseline after run-in and washout (BDP). RESULTS: After chronic dosing, IOS outcomes at trough except for R20 were all significantly improved with OLO/TIO compared to OLO. For the primary end-point of total airway resistance (as R5), the mean difference (95%CI) at trough was 0.06 (0.015-0.10) kPa/l/s, peripheral airways resistance (as R5-R20) 0.03 (0.003-0.06) kPa/l/s, peripheral lung reactance area (as AX) 0.38 (0.08-0.68) kPa/l and resonant frequency (as RF) 2.28 (0.45-4.12) Hz. FEF25-75 at trough was also better with OLO/TIO vs TIO: 0.93 (0.86 - 0.95) l/s while FEV1 was not different. CONCLUSIONS: ICS/LABA/LAMA was superior to ICS/LABA on trough small airway outcomes in asthma patients who smoke.
