Economic impact of implementing prescription of single-inhaler triple therapies versus current multiple-inhaler triple therapies for COPD in the Apulia Region.

BACKGROUND: The most impacting direct costs associated to COPD for the National Health Systems (NHS) are those related to accesses to the emergency room and hospital admissions, due to the onset of one or more COPD exacerbations. At the same time, severe COPD treatment, that often require a combination of medicaments, represents a substantial economic burden for the National Health Systems (NHS). This study aimed to evaluate the potential saving deriving from the implementation in the prescription of the two currently available single-inhaler triple therapies (SITTs) versus the currently used multiple-inhaler triple therapies (MITTs) in an eligible COPD population residing in the Apulia Region. METHODS: A budget impact model was developed hypothesizing the progressive replacement of the different MITTs on the reference market (Scenario A) with the pre-established SITTs, assuming a degree of penetration of 30%, 50% and 100% (Scenario B). Drug costs were based on prices published on the Official Gazette and therapy durations were based on prescribing information over the year 2019 (IQVIA™ prescription dataset). RESULTS: Our analysis showed that the extemporaneous MITT with the highest prevalence on the reference market was the inhaled corticosteroids/long-acting ß2-agonists (ICS/LABA) combination plus a long-acting muscarinic antagonists (LAMA). This association of medicaments was paradoxically also the one associated to the highest expense value. The expanded use of a pre-established ICS/LAMA/LABA SITT was associated to a significant economic saving, ranging from a minimum of -€ 1,108,814 (SITT use: 30%) to a maximum of -€ 3,658,950 (SITT use: 100%). The cheapest pre-established SITT contained the fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) combination. CONCLUSION: A pre-fixed ICS/LAMA/LABA SITT is cost-saving, compared to the different currently used extemporaneous MITTs. Clinicians should consider the potential benefits of finding less expensive regimens while maintaining adequate efficacy in the prescriptive decision making process of COPD patients.

Outcomes Following Initiation of Triple Therapy with Fluticasone Furoate/Umeclidinium/Vilanterol versus Multiple-Inhaler Triple Therapy Among Medicare Advantage with Part D Beneficiaries and Those Commercially Enrolled for Health Care Insurance in the United States.

Purpose: Patients with chronic obstructive pulmonary disease (COPD) have been shown to benefit from triple therapy commonly delivered by multiple-inhaler triple therapy (MITT); however, the complexity of MITT regimens may decrease patient adherence. Fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), a once-daily single-inhaler triple therapy (SITT), became available in the United States (US) in 2017, but real-world data comparing outcomes for SITT versus MITT are currently limited. This study compared outcomes among patients with COPD initiating MITT versus SITT with FF/UMEC/VI who were either Medicare Advantage with Part D (MAPD) beneficiaries or commercial enrollees in the US. Methods: Retrospective study using administrative claims data from the Optum Research Database for patients with COPD who initiated FF/UMEC/VI or MITT between September 1, 2017, and March 31, 2019 (index date: first pharmacy claim for FF/UMEC/VI cohort; earliest day of ≥30 consecutive days-long period of overlap in the day's supply of all triple therapy components for MITT cohort). COPD exacerbations, adherence to triple therapy, and all-cause and COPD-related health care resource utilization (HCRU) and costs were compared between FF/UMEC/VI and MITT initiators. Results: In total, 4659 FF/UMEC/VI initiators and 9845 MITT initiators for the MAPD population, and 821 FF/UMEC/VI initiators and 1893 MITT initiators for the commercial population were included in the study. MAPD beneficiaries initiating FF/UMEC/VI had a significantly lower annual rate of severe exacerbations compared to MITT initiators (0.26 vs 0.29; p=0.014). They also had a significantly higher mean adherence (proportion of days covered) (0.51 vs 0.37; p<0.001) and significantly lower all-cause and COPD-related inpatient stays compared to MITT initiators ([32.02% vs 34.27%; p=0.017], [16.09% vs 17.72%; p=0.037]). Trends were similar among the commercial population, but the results were not statistically significant. Conclusion: FF/UMEC/VI initiators had significantly fewer severe exacerbations, higher triple therapy adherence, and lower HCRU costs compared to MITT initiators for MAPD beneficiaries.

Extrafine single inhaler triple therapy effectiveness in COPD patients previously treated with multiple-inhaler triple therapy: the TRIWIN study.

BACKGROUND: The extrafine single inhaler triple therapy (efSITT) containing beclomethasone dipropionate/formoterol fumarate/glycopyrronium 87/5/9 µg has proved to be efficacious in patients with chronic obstructive pulmonary disease (COPD) in randomized control trials. OBJECTIVE: TRIWIN study evaluated the effectiveness of efSITT delivering beclomethasone dipropionate/formoterol fumarate/glycopyrronium 87/5/9 µg in COPD patients previously treated with multiple-inhaler triple therapy (MITT) in a real-world study in Greece. DESIGN: Prospective, multicenter, observational, non-interventional study was conducted over 24 weeks. METHODS: A total of 475 eligible patients had moderate-to-severe COPD, an indication for treatment with efSITT, and were symptomatic despite receiving MITT. COPD Assessment Test (CAT) score, pulmonary function parameters, use of rescue medication, and adherence to inhaler use were recorded at baseline (Visit 1), 3 (Visit 2), and 6 months (Visit 3) after treatment. RESULTS: Mean CAT score decreased from 21.4 points at Visit 1, to 16.6 at Visit 2 and 15.1 at Visit 3 (p < 0.001 for all pair comparisons). At Visit 3, 79.8% of patients reached a CAT improvement exceeding minimal clinically important difference (⩾2), compared to baseline. Mean forced expiratory volume in 1 s (%pred.) increased from 55.4% at Visit 1 to 63.5% at the end of study period (p < 0.001), while mean forced vital capacity (%pred.) increased from 71.1% at Visit 1, to 76.7% at Visit 3 (p < 0.001). The mean Test of Adherence to Inhalers score increased from 42.5 to 45.3 and 46.3 points, for the three visits, respectively (p < 0.001 comparing Visits 1/2 and Visits 1/3; p = 0.006 comparing Visits 2/3). The percentage of patients showing good adherence rose from 33.7% at baseline to 58.3% at Visit 3. The percentage of patients using rescue medication during the last month dropped from 16.2% to 7.4% at the end of study period (p < 0.001). Pulmonary function parameters also improved. CONCLUSION: The TRIWIN results suggest that extrafine beclomethasone dipropionate/formoterol fumarate/glycopyrronium is effective in improving health status, pulmonary function, and adherence and in reducing rescue medication use in COPD patients previously treated with MITT, in a real-world setting in Greece.

Comparison of treatment persistence, adherence, and risk of exacerbation in patients with COPD treated with single-inhaler versus multiple-inhaler triple therapy: A prospective observational study in China.

Aim: This study sought to compare treatment persistence, adherence, and risk of exacerbation among patients with COPD treated with single-inhaler triple therapy (SITT) and multiple-inhaler triple therapy (MITT) in the Chinese population. Methods: This was a multicenter, prospective observational study. Patients with COPD from ten hospitals in Hunan and Guangxi provinces in China were recruited from 1 January 2020 to 31 November 2021 for the study and were followed up for one year. Treatment persistence, adherence, and exacerbation rates during the 12-month follow-up were analyzed in COPD patients treated with SITT and MITT. Results: A total of 1,328 patients were enrolled for final analysis, including 535 (40.3%) patients treated with SITT and 793 (59.7%) treated with MITT. Of these patients, the mean age was 64.9 years and most patients were men. The mean CAT score was 15.2 ± 7.1, and the median (IQR) FEV1% was 54.4 (31.2). The SITT group had a higher mean CAT score, more patients with mMRC >1, and lower mean FEV1% and FEV1/FVC than the MITT patients. Moreover, the proportion of patients with ≥1 exacerbation in the previous year was higher in the SITT cohort. SITT patients had, compared to MITT patients, a higher proportion of adherence (proportion of days covered, PDC) ≥0.8 (86.5% vs. 79.8%; p = 0.006), higher treatment persistence [HR: 1.676 (1.356-2.071), p < 0.001], lower risk of moderate-to-severe exacerbation [HR: 0.729 (0.593-0.898), p = 0.003], and severe exacerbation [HR: 0.675 (0.515-0.875), p = 0.003], as well as reduced all-cause mortality risk [HR: 0.475 (0.237-0.952), p = 0.036] during the 12-month follow-up. Persistence was related to fewer future exacerbations and mortality than non-persistence in the SITT and MITT groups. Conclusion: Patients with COPD treated with SITT showed improved treatment persistence and adherence, as well as a reduction in the risk of moderate-to-severe exacerbation, severe exacerbation, and mortality compared to patients treated with MITT in the Chinese population.

COPD Exacerbations, Costs, and Health Care Resource Utilization Before and After Initiation of Fluticasone Furoate/Umeclidinium/Vilanterol in Routine Care in the USA.

Purpose: To examine the impact of initiating fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) in a single device on chronic obstructive pulmonary disease (COPD) exacerbations, COPD exacerbation-related costs, and all-cause and COPD-related healthcare resource utilization (HCRU) and costs in patients with COPD. Methods: Retrospective database analysis of patients with COPD aged ≥40 years who initiated FF/UMEC/VI between September 1, 2017, and December 31, 2018 (index date: first pharmacy claim for FF/UMEC/VI), following evidence of multiple-inhaler triple therapy (MITT) (≥30 consecutive days) in the year prior to index. COPD exacerbations, COPD exacerbation-related costs, and all-cause and COPD-related HCRU and costs were compared between the baseline period (12 months prior to and including index) and follow-up period (12 months following index). Results: Data from 912 patients (mean [SD] age: 71.2 [8.1], 51.2% female) were included in the analyses. Among the overall cohort, mean count of total COPD exacerbations (moderate or severe) per patient was statistically significantly lower in the follow-up period compared to baseline (1.2 vs 1.4, p=0.001). The proportion of patients with ≥1 COPD exacerbation (moderate or severe) was also statistically significantly lower in the follow-up period compared to baseline (56.4% vs 62.4%, p=0.001). All-cause and COPD-related HCRU were similar during follow-up compared to baseline, although the proportion of patients with COPD-related ambulatory visits was lower during follow-up (p<0.001). COPD-related office visit costs, emergency room visit costs, and pharmacy costs were statistically significantly lower during follow-up compared to baseline (p<0.001; p=0.019; p<0.001, respectively). Conclusion: In a real-world setting, patients on MITT who subsequently initiated FF/UMEC/VI in a single device had significant reductions in the rate of COPD exacerbations (moderate or severe). Switching to FF/UMEC/VI also resulted in improvements in some HCRU and cost outcomes. These data support the use of FF/UMEC/VI among patients at high risk of exacerbation to reduce future risk and improve outcomes.

Benefit of Prompt Vs Delayed Initiation of Triple Therapy Following an Exacerbation in Patients with COPD in Japan: A Retrospective Cohort Study.

Purpose: There is currently limited evidence for the optimal timing of triple therapy initiation in Japan, which is crucial for optimizing strategies for the effective treatment of chronic obstructive pulmonary disease (COPD). This study assessed the impact of prompt vs delayed initiation of triple therapy following a COPD exacerbation on clinical and economic outcomes in patients in Japan. Patients and Methods: Retrospective cohort study of patients in the Medical Data Vision Co., Ltd. database initiating triple therapy as single-inhaler triple therapy (fluticasone furoate/umeclidinium/vilanterol or budesonide/glycopyrronium/formoterol) or multiple-inhaler triple therapy within 180 days of a moderate-to-severe exacerbation (index). For the main analysis, patients were categorized as prompt or delayed initiators, initiating triple therapy within 0-30 days or 31-180 days of index, respectively. Inverse probability of treatment weighting based on propensity scores was used to adjust for measured confounders between prompt and delayed cohorts. Results: For the main analysis, 610 (60.3%) and 402 (39.7%) patients were prompt and delayed initiators, respectively. The rate of subsequent moderate-to-severe exacerbations following index exacerbation was numerically lower in prompt vs delayed initiators (weighted rate ratio 0.95, 95% confidence interval [CI]: 0.74-1.21; P = 0.6603). Time-to-first subsequent moderate-to-severe exacerbation increased significantly in prompt vs delayed initiators (weighted hazard ratio 0.77, 95% CI: 0.64-0.93; P = 0.0053). In patients indexed on a severe exacerbation, delayed initiation resulted in significantly higher 90-day all-cause readmissions vs prompt initiation (42.1% vs 30.6%; P = 0.0329 [weighted estimates]). Weighted healthcare resource utilization rates were numerically lower in prompt vs delayed initiators, and weighted direct costs (all cause and COPD-related) were significantly lower in prompt initiators. Conclusion: This real-world study demonstrated that earlier initiation of triple therapy resulted in several benefits in clinical outcomes for COPD and may also reduce the economic burden of COPD management in Japan.

Characteristics of New Users of Single- and Multiple-Inhaler Triple Therapy for COPD in Primary Care in England.

Purpose: Inhaled triple therapy is recommended for patients with chronic obstructive pulmonary disease (COPD) who have poorly controlled symptoms and to reduce the risk of exacerbations. This study assessed the clinical characteristics of new users of single- and multiple-inhaler triple therapy (SITT and MITT) treated in a primary care setting in England. Patients and Methods: This cross-sectional, observational study used data from an electronic health record database (CPRD Aurum) of COPD patients registered with a primary care practice in England, with linkage to a secondary care database. Patients were required to have initiated a new triple therapy (index) between November 2017 and November 2018 and have ≥12 months of available medical history prior to the index date. Results: In total, 3536 patients initiated fluticasone furoate, umeclidinium, and vilanterol (FF/UMEC/VI) SITT for the first time: 65% had a Medical Research Council (MRC) dyspnea score ≥3, 45% had forced expiratory volume in 1 second (FEV1)% predicted <50%, and 64% had a moderate or severe exacerbation in the previous 12 months. The majority (83%) of new FF/UMEC/VI users had a history of MITT use. Immediately prior to FF/UMEC/VI initiation, 46% received MITT, 25% received an inhaled corticosteroid (ICS)/long-acting ß2-agonist (LABA), 12% received long-acting muscarinic antagonist (LAMA)/LABA, and 14% stepped up directly from LAMA monotherapy. A second cohort of 6540 patients initiated triple therapy (SITT or MITT) for the first time. COPD severity (airflow limitation, exacerbation history) was worse among patients initiating SITT versus MITT. In the 12 months before triple-therapy initiation, ICS/LABA was the most common treatment; a step up from LAMA/LABA was more common among patients initiating FF/UMEC/VI (34%) or beclomethasone/formoterol/glycopyrronium bromide SITT (25%) than MITT (14%). Conclusion: First-time triple therapy was frequently initiated in patients with COPD inadequately controlled on maintenance therapy. General practitioners in England generally identify appropriate patients who require initiation of triple therapy.

Adherence and persistence to once-daily single-inhaler versus multiple-inhaler triple therapy among patients with chronic obstructive pulmonary disease in the USA: A real-world study.

BACKGROUND: Triple therapy comprising an inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting ß2 agonist (ICS/LAMA/LABA) is recommended for chronic obstructive pulmonary disease (COPD) patients at risk of exacerbation. Multiple-inhaler triple therapy (MITT) is associated with poor adherence and persistence; however, these outcomes have not been evaluated for single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI). METHODS: This retrospective analysis of the IQVIA PharMetrics Plus claims database identified patients with COPD initiating triple therapy between 18 September 2017 and 30 June 2019. The first date of single-inhaler FF/UMEC/VI dispensing, or first day of overlapping ICS, LAMA, and LABA medications for MITT users, defined the index date. Patients were ≥40 years, had ≥12 months of continuous insurance coverage pre-index (baseline) and ≥6 months' coverage post-index; those with MITT during baseline were excluded. Inverse probability weighting was used to balance baseline characteristics. Adherence was assessed using proportion of days covered (PDC) and was evaluated using linear and log-binomial models. Persistence (non-persistence identified as >30-day gap between fills) was evaluated using Cox models. RESULTS: 9942 patients (FF/UMEC/VI: 2782; MITT: 7160) were included. Adherence was significantly higher for FF/UMEC/VI versus MITT users (mean PDC, 0.66 vs. 0.48; p < 0.001), and FF/UMEC/VI users were twice as likely to be adherent (PDC ≥0.8) than MITT users (46.5% vs. 22.3%; risk ratio [95% CI]: 2.08 [1.85-2.30]; p < 0.001). After 12 months, significantly more FF/UMEC/VI users persisted on therapy than MITT users (35.7% vs. 13.9%; hazard ratio [95% CI]: 1.91 [1.81-2.01]; p < 0.001). CONCLUSIONS: COPD patients initiating single-inhaler FF/UMEC/VI had significantly improved adherence and persistence compared with MITT.

Adherence and Persistence to Single-Inhaler Versus Multiple-Inhaler Triple Therapy for Asthma Management.

BACKGROUND: Treatment guidelines recommend triple therapy for patients with asthma who remain uncontrolled on inhaled corticosteroid/long-acting ß2-agonist therapy. Previously, triple therapy was only available via multiple inhalers. Single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) is approved as maintenance treatment for asthma; however, real-world information on adherence and persistence is limited. OBJECTIVE: To compare adherence and persistence among adult patients with asthma receiving single-inhaler FF/UMEC/VI versus multiple-inhaler triple therapy (MITT) in the United States. METHODS: This retrospective cohort study used IQVIA PharMetrics Plus data to evaluate patients with asthma who initiated once-daily FF/UMEC/VI 100/62.5/25 mcg or MITT between September 18, 2017, and September 30, 2019. Inverse probability weighting and multivariable regression adjusted for differences in characteristics between the FF/UMEC/VI and MITT cohorts. Adherence was assessed using proportion of days covered (PDC) and proportion of patients achieving PDC ≥0.8 and PDC ≥0.5. Non-persistence was identified as a >45-day gap between fills. RESULTS: The study included 1396 FF/UMEC/VI and 5115 MITT initiators. Three months after initiation, FF/UMEC/VI users had significantly higher mean PDC versus MITT users (0.68 vs 0.59; P < .001) and 31% more likely to be adherent (PDC ≥0.8; 40.6% vs 31.3%; adjusted risk ratio [95% confidence interval (CI)]: 1.31 [1.13-1.54]; P < .001). Similar patterns were observed at 6 and 12 months post initiation. In addition, FF/UMEC/VI users were 49% more likely to persist at 12 months than MITT users (25.9% vs 15.1%, adjusted hazard ratio [95% CI]: 1.49 [1.39-1.60]; P < .001). CONCLUSIONS: Patients with asthma initiating triple therapy with FF/UMEC/VI had significantly better adherence and persistence compared with MITT initiators.

Clinical Characteristics, Treatment Persistence, and Outcomes Among Patients With COPD Treated With Single- or Multiple-Inhaler Triple Therapy: A Retrospective Analysis in Spain.

BACKGROUND: COPD is a leading cause of death and disability. COPD therapy goals include reducing exacerbations and improving symptom control. Single-inhaler triple therapy (SITT) or multiple-inhaler triple therapy (MITT) is indicated for patients with frequent exacerbations despite bronchodilator therapy. No available evidence compares SITT vs MITT in Spain in terms of treatment persistence, exacerbations, and other outcomes. RESEARCH QUESTION: Do COPD patients in Spain initiating SITT vs MITT have improved persistence, exacerbations, and health care resource utilization? STUDY DESIGN AND METHODS: This real-world, observational, retrospective cohort study analyzed electronic health records in the Spanish National Healthcare System BIG-PAC database to identify COPD patients aged ≥ 40 years initiating SITT or MITT (using two or three inhalers) between June 1, 2018 and December 31, 2019. Comparative data on persistence (allowing up to 60 days without prescription refill), exacerbation rates, and health care resource utilization and costs during 12-month follow-up were analyzed. Multivariate adjusted analyses were performed. RESULTS: Eligible patients (N = 4,625) initiating SITT (n = 1,011) or MITT (n = 3,614) had a mean age of 70.9 years; most were male (73.9%) with mainly moderate (62.0%) or severe (26.5%) airflow limitation. Between-cohort baseline characteristics were similar. At 12-month follow-up, SITT patients had higher persistence (hazard ratio [HR] = 1.37; 95% CI = 1.22-1.53; P < .001), reduced risk of exacerbations (HR = 0.68; 95% CI = 0.61-0.77; P = .001), and lower all-cause mortality risk (HR = 0.67; 95% CI = 0.63-0.71, P = .027), compared with MITT patients. SITT was associated with significantly reduced health care resource use (mean annual cost savings: €403 vs MITT). For both SITT and MITT, persistence was associated with improved exacerbation rates vs nonpersistence, and substantial adjusted mean annual cost savings (€2,115 and €2,700, respectively). INTERPRETATION: Patients initiating SITT had a clinically relevant improvement in persistence leading to reductions in mortality, incidence of exacerbations, and health care resource use with consequent mean cost savings.

Quantifying the Economic Impact of Delayed Multiple-Inhaler Triple Therapy Initiation in Patients with COPD: A Retrospective Cohort Study of Linked Electronic Medical Record and Hospital Administrative Data in England.

PURPOSE: To assess if early multiple-inhaler triple therapy (MITT) initiation in patients with chronic obstructive pulmonary disease (COPD) reduces subsequent healthcare resource utilization (HCRU), direct medical costs, and acute exacerbations of COPD (AECOPDs). PATIENTS AND METHODS: This retrospective, longitudinal cohort study used electronic health records and linked hospital administrative data in England. COPD patients with an AECOPD between July 2012 and May 2016 (index), and who subsequently started MITT within 180 days were eligible. Patients with an AECOPD 6 months prior to index were excluded. HCRU, direct healthcare costs, and AECOPDs were assessed in the following 24-month period for early (≤30 days) and delayed (31-180 days) MITT initiators. RESULTS: A total of 934 patients were included in the analysis and categorized as early (n=367, 39%) or delayed (n=567, 61%) MITT initiators. Mean patient age was 68.5 years and 53.2% were male. A significantly higher proportion of delayed MITT initiators required ≥1 outpatient appointment (all-cause) compared with early MITT initiators (87% vs 79%; p=0.0016). A significantly higher proportion of delayed MITT initiators required ≥1 COPD­related inpatient stay versus early MITT initiators (47% vs 40%; p=0.0262). Over the 24-month follow-up, mean all-cause and COPD-related total healthcare costs were significantly higher in delayed MITT initiators compared with early MITT initiators (all­cause: £11,348 vs £8126; p=0.0011; COPD-related: £7307 vs £4535; p=0.0009). CONCLUSION: Delayed initiation of multiple-inhaler triple therapy was associated with higher all-cause and COPD-related costs, suggesting that earlier initiation of triple therapy in COPD patients may help reduce the economic burden on the healthcare system.

Effect of Age on Efficacy and Safety of Fluticasone Furoate/Vilanterol (FF/VI), Umeclidinium (UMEC), and UMEC + FF/VI in Patients with Chronic Obstructive Pulmonary Disease: Analyses of Five Randomized Clinical Trials.

Introduction: Concerns have been raised about the practical use and clinical benefits of medications and inhalers in older patients with chronic obstructive pulmonary disease (COPD). Here, we report analyses according to age from five clinical trials evaluating medications administered using the ELLIPTA dry-powder inhaler (DPI). Methods: Efficacy and safety according to age groups (<65 and ≥65 years) were assessed using data from five clinical trials in patients ≥40 years of age with symptomatic COPD. There was a mix of pre-specified and post hoc analyses of two 24-week trials with fluticasone furoate (FF)/vilanterol (VI) 100/25 µg; one 24-week trial with umeclidinium (UMEC) 62.5 µg; and two 12-week trials with UMEC 62.5 µg + FF/VI 100/25 µg. The primary endpoint was trough forced expiratory volume in 1 second (FEV1) obtained 23 and 24 hours after dosing on the last day of the study. Results: A total of 2876 patients <65 years of age and 2148 patients ≥65 years of age were enrolled across all studies of whom 1333 and 1111 patients, respectively, received treatment at the doses presented. Statistically significant and clinically meaningful treatment differences in improvement from baseline in mean trough FEV1 were reported for active comparators versus placebo at study end for both <65 and ≥65 years subgroups (FF/VI vs placebo: 143 mL and 111 mL; UMEC vs placebo: 110 mL and 123 mL; UMEC + FF/VI vs placebo + FF/VI: 136 mL and 105 mL; p<0.001 for all comparisons). The incidence of adverse events reported for active treatments was similar between age groups. Conclusion: These data provide evidence to support the use of FF/VI, UMEC, or UMEC + FF/VI, all delivered via the ELLIPTA DPI, to treat older (≥65 years) and younger (<65 years) patients with 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.

A Real-World Analysis of Treatment Patterns and Clinical Characteristics Among Patients with COPD Who Initiated Multiple-Inhaler Triple Therapy in New Zealand.

Purpose: Real-world data on maintenance treatment and prescription patterns provide insights into healthcare management among patients with chronic obstructive pulmonary disease (COPD), which benefits our understanding of current COPD treatment patterns in New Zealand. Methods: We retrospectively analyzed real-world data from the HealthStat general practice database to evaluate treatment patterns among patients with COPD in New Zealand who initiated multiple-inhaler triple therapy (MITT): inhaled corticosteroid (ICS) + long-acting muscarinic antagonist + long-acting ß2-agonist (LABA). Our main objective described treatment patterns (class, duration, modification, persistence, and adherence) and characteristics of patients with COPD initiating MITT between 1 May 2016 and 30 April 2017, with 12-months' follow-up. We also assessed the number of patients receiving MITT between 2015 and 2017, among a larger patient population receiving long-acting bronchodilator and ICS-containing therapies. Results: Of 6249 eligible patients, 421 (mean age 67.3 years; mean number exacerbations at baseline 1.8) initiated MITT: 59.1% received combination ICS/LABA therapy prior to MITT initiation, and median treatment duration prior to MITT initiation was 350 days. Overall, 33.5% of patients remained on index treatment for 12 months. Of the remaining patients who modified treatment (on average at 144.4 days), those who had a direct switch (24.9%) or retreatment (13.5%) remained on MITT, 19.7% of patients stepped down to mono/dual therapy, and 8.3% discontinued treatment. Mean (standard deviation) persistence to any MITT over 12 months was 47.3 (50.0), and 53.4% of patients were considered adherent to MITT. Total proportions of patients receiving long-acting bronchodilator therapy and MITT increased between 2015 and 2017. Conclusion: Most patients with COPD in New Zealand who initiated MITT had characteristics appropriate for triple therapy prescription, suggesting prescription behavior among general practitioners was largely consistent with treatment guidelines. Our findings may help optimize treatment decisions, with a focus on improving long-term triple therapy persistence and adherence.

Clinical burden of illness among patients with severe eosinophilic COPD.

Background: There are currently limited real-world data on the clinical burden of illness in patients with COPD who continue to exacerbate despite receiving triple therapy. The aim of this study was to compare the burden of COPD in patients with and without a phenotype characterized by a high blood eosinophil count and high risk of exacerbations while receiving triple therapy. Methods: This retrospective cohort study (GSK ID: 207323/PRJ2647) used UK Clinical Practice Research Datalink records linked with Hospital Episode Statistics. Eligible patients had a COPD medical diagnosis code recorded between January 1, 2004 and December 31, 2014, and a blood eosinophil count recorded on/after that date. Patients were followed from index date (first qualifying blood eosinophil count) until December 31, 2015. The study phenotype was defined as ≥2 moderate/≥1 severe acute exacerbation of COPD (AECOPD) in the year prior to the index date, current use of multiple-inhaler triple therapy (MITT), and blood eosinophil count ≥150 cells/µL on the index date. Outcomes measured during follow-up included moderate/severe AECOPDs, severe AECOPDs, all-cause mortality, primary care (GP) clinical consultations, and non-AECOPD-related unscheduled hospitalizations. Results: Of 46,814 patients eligible for inclusion, 2512 (5.4%) met the definition of the study phenotype. Adjusted rate ratios (95% CI) of moderate/severe AECOPDs and all-cause mortality in patients with the study phenotype versus those without were 2.32 (2.22, 2.43) and 1.26 (1.16, 1.37), respectively. For GP visits and non-AECOPD-related unscheduled hospitalizations, adjusted rate ratios (95% CI), in patients with the study phenotype versus those without, were 1.09 (1.05, 1.12) and 1.31 (1.18, 1.46), respectively. Conclusion: Patients with COPD and raised blood eosinophil counts who continue to exacerbate despite MITT represent a distinct subgroup who experience substantial clinical burden and account for high healthcare expenditure. There is a need for more effective management and therapeutic options for these patients.

Medication adherence and persistence in chronic obstructive pulmonary disease patients receiving triple therapy in a USA commercially insured population.

INTRODUCTION: This longitudinal, retrospective cohort study of patients with COPD describes baseline characteristics, adherence, and persistence following initiation of inhaled corticosteroids (ICS)/long-acting ß2-agonists (LABA)/long-acting muscarinic antagonists (LAMA) from multiple inhaler triple therapy (MITT). METHODS: Patients aged ≥40 years receiving MITT between January 2012 and September 2015 were identified from the IQVIA™ Real-world Data Adjudicated Claims-USA database. MITT was defined as subjects with ≥1 overlapping days' supply of three COPD medications (ICS, LABA, and LAMA). Adherence (proportion of days covered, PDC) and discontinuation (defined as a gap of 1, 30, 60, or 90 days of supply in any of the three components of the triple therapy) were calculated for each patient over 12 months of follow-up. In addition, analyses were stratified by number of inhalers. RESULTS: In total, 14,635 MITT users were identified (mean age, 62 years). Mean PDC for MITT at 12 months was 0.37%. Mean PDC for the ICS/LABA and LAMA component at 12 months was 49% (0.49±0.31; median, 0.47) and 54% (0.54±0.33; 0.56), respectively. The proportion of adherent patients (PDC ≥0.8) at 12 months was 14% for MITT. Allowing for a 30-day gap from last day of therapy, 86% of MITT users discontinued therapy during follow-up. CONCLUSION: Patients with COPD had low adherence to and persistence with MITT in a real-world setting. Mean PDC for each single inhaler component was higher than the mean PDC observed with MITT. Reducing the number of inhalers may improve overall adherence to intended triple therapy.
