Hospital Admission and Readmission Among US Patients Receiving Umeclidinium/Vilanterol or Tiotropium as Initial Maintenance Therapy for Chronic Obstructive Pulmonary Disease.

ABSTRACT:

Introduction

Patients hospitalized for chronic obstructive pulmonary disease (COPD) exacerbations are at risk of further readmissions, increased treatment costs, and excess mortality. This study evaluated inpatient admissions and readmissions in patients receiving initial maintenance therapy with umeclidinium/vilanterol (UMEC/VI) versus tiotropium (TIO).

Methods

This retrospective, matched cohort study identified patients with COPD who initiated maintenance therapy with UMEC/VI or TIO from Optum's de-identified Clinformatics Data Mart database between January 1, 2013, and December 31, 2018 (index date defined as earliest dispensing). Eligibility criteria included: ≥ 1 medical claim for COPD pre-index or on the index date; ≥ 12 months of continuous eligibility pre-index; age ≥ 40 years at index; no pre- or post-index asthma diagnosis; and no pre-index claims for medications containing inhaled corticosteroids, long-acting β₂-agonists, or long-acting muscarinic antagonists. Outcomes included time to first on-treatment COPD-related inpatient admission, rate of on-treatment COPD-related admissions, and rate of all-cause and COPD-related readmissions within 30 and 90 days. Propensity score matching was used to adjust for potential confounders.

Results

Matched UMEC/VI and TIO cohorts each included 7997 patients and were balanced on baseline characteristics (mean age 70.9 years; female 47.1-47.6%). Over 12 months, patients initiating UMEC/VI had significantly reduced risk (hazard ratio [95% CI]: 0.87 [0.79, 0.96]; p = 0.006) and rates (rate ratio [95% CI]: 0.80 [0.72, 0.92]; p = 0.008) of COPD-related inpatient admissions compared with TIO. While all-cause readmission rates were similar between treatment cohorts, readmission rates among patients with an initial admission length of stay of 1-3 days were numerically lower for UMEC/VI versus TIO (30-day readmissions: 10.5% vs. 12.4%; 90-day readmissions: 15.5% vs. 19.8%). Similar patterns were observed for COPD-related readmissions.

Conclusions

These findings highlight the real-world benefits of dual therapy with UMEC/VI versus TIO in reducing inpatient admissions and readmissions in patients with COPD, which may translate to lower healthcare costs.

Project description:BackgroundAdherence 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).MethodsThis 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 β2-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.ResultsEach 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.ConclusionsThese findings provide valuable information for physicians considering UMEC/VI or TIO as initial maintenance therapy options for patients with COPD.

Project description:IntroductionDual bronchodilator therapy is reserved as a second-line treatment in patients with chronic obstructive pulmonary disease (COPD) and provides benefits in lung function and health status versus monotherapy. The aim of this study was to determine whether early initiation of a dual bronchodilator versus monotherapy reduced the risk of deterioration in COPD.MethodsThis post hoc pooled analysis investigated the efficacy and safety of umeclidinium/vilanterol (UMEC/VI) 62.5/25 mcg/day compared with tiotropium (TIO) 18 mcg/day in a maintenance-naïve (MN) subgroup of patients relative to the intent-to-treat (ITT) population from three 6-month active comparator studies (n = 1747). Other treatment arms (UMEC/VI 125/25, VI 25 and UMEC 125) comprised 850 patients in total but were not included in this analysis. The primary endpoint was trough forced expiratory volume in 1 s (FEV1). St George's Respiratory Questionnaire (SGRQ) score, rescue medication use, and a novel composite endpoint of short-term clinically important deterioration (CID; ≥100 ml decrease in trough FEV1, ≥4-unit increase in SGRQ score, or a COPD exacerbation) were also assessed.ResultsUMEC/VI improved trough FEV1 versus TIO at day 169 [least squares mean (95% confidence interval): MN: 146 ml (102-189) and ITT: 95 ml (71-118); both P < 0.001]. Both UMEC/VI and TIO improved SGRQ and rescue use in the two populations, with greater improvements in rescue use with UMEC/VI versus TIO. UMEC/VI reduced the risk of short-term clinically important deterioration versus TIO [hazard ratio; 95% confidence interval: MN: 0.66 (0.51-0.85); ITT: 0.62 (0.54-0.71), both P ≤ 0.001]. Adverse events were similar across both populations and treatments.ConclusionsEarly use of dual-bronchodilator therapy has superior efficacy on lung function and may reduce the risk of short-term deterioration compared to monotherapy in symptomatic patients with COPD.Clinical trial registrationGSK analysis 202066 (NCT01316900/DB2113360, NCT01316913/DB2113374, NCT01777334/ZEP117115).FundingThis study was funded by GSK.

Project description:BackgroundBoth long-acting muscarinic antagonists (LAMAs) and long-acting β2-agonists (LABAs) are widely used in the treatment of chronic obstructive pulmonary disease (COPD). A novel LAMA/LABA combination of umeclidinium/vilanterol (UMEC/VI; 62.5 μg/25 μg) is approved for chronic obstructive pulmonary disease (COPD) treatment.ObjectiveThis study aimed to assess the efficacy and cost-effectiveness of UMEC/VI versus tiotropium (TIO) 18 μg in symptomatic patients with COPD from the perspective of the Chinese National Healthcare System.MethodsA simple analysis included three studies in the meta-analysis that compared UMEC/VI with TIO. A Markov model was developed to estimate the cost-effectiveness of UMEC/VI compared with TIO treatment in symptomatic patients with COPD. First, utilities, clinical efficacy, and adverse events obtained from the literature were utilized as model inputs. Costs were from Chinese average data, including local data. Costs were expressed in dollars based on 2020 prices. Then, the model outputs including drug costs, other medical costs, and total costs, and quality-adjusted life years (QALYs) were estimated. Costs and outcomes were discounted at a 5% annual rate. Furthermore, incremental cost-effective ratios (ICERs) were analyzed. Finally, the influences of changing parameters on the uncertainty of the results were assessed by means of one-way and probabilistic sensitivity analyses.ResultsThis study revealed that UMEC/VI treatment had a higher rate of clinical efficacy in comparison with TIO, and the differences in the rate of adverse events between the two treatments were not significant. The results indicated that UMEC/VI was superior to TIO, which provided an increase in QALYs (0.002) and a total cost savings of $765.67 per patient over 3 years. In the base case, the ICER of UMEC/VI is -$397468.04/QALY compared with TIO, suggesting that UMEC/VI may be considered a dominant option over TIO. According to the Chinese medical system, the probability of UMEC/VI being cost-effective was 61.6% at a willingness-to-pay (WTP) of $31554/QALY. Sensitivity analyses confirmed that the results were robust.ConclusionUMEC/VI could be considered a cost-effective treatment compared with TIO in symptomatic COPD patients from the Chinese National Healthcare System perspective. These results may help decision-makers in China when making judgements on which treatments to administer.

Project description:IntroductionThe fixed-dose, long-acting bronchodilator combination of umeclidinium/vilanterol (UMEC/VI) has not previously been compared with a combination of a long-acting muscarinic antagonist and long-acting β2-agonist in patients with chronic obstructive pulmonary disease (COPD).MethodsThis 12-week, randomized, blinded, triple-dummy, parallel-group, non-inferiority study compared once-daily UMEC/VI 62.5/25 mcg with once-daily tiotropium (TIO) 18 mcg + indacaterol (IND) 150 mcg in patients with moderate-to-very-severe COPD. The primary endpoint was the trough forced expiratory volume in 1 s (FEV1) on day 85 (predefined non-inferiority margin -50 mL), and the secondary endpoint was the 0- to 6-h weighted mean (WM) FEV1 on day 84. Other efficacy endpoints [including rescue medication use, the Transition Dyspnea Index (TDI) focal score, and the St. George's Respiratory Questionnaire (SGRQ) score] and safety endpoints [adverse events (AEs), vital signs, and COPD exacerbations] were also assessed.ResultsTrough FEV1 improvements were comparable between treatment groups [least squares (LS) mean changes from baseline to day 85: UMEC/VI 172 mL; TIO + IND 171 mL; treatment difference 1 mL; 95 % confidence interval (CI) -29 to 30 mL], demonstrating non-inferiority between UMEC/VI and TIO + IND. The treatments produced similar improvements in the trough FEV1 at other study visits and the 0- to 6-h WM FEV1 (LS mean changes at day 84: UMEC/VI 235 mL; TIO + IND 258 mL; treatment difference -23 mL; 95 % CI -54 to 8 mL). The results for patient-reported measures (rescue medication use, TDI focal score, and SGRQ score) were comparable; both treatments produced clinically meaningful improvements in TDI and SGRQ scores. The incidence of AEs and COPD exacerbations, and changes in vital signs were similar for the two treatments.ConclusionUMEC/VI and TIO + IND, given once daily, provided similar improvements in lung function and patient-reported outcomes over 12 weeks in patients with COPD, with comparable tolerability and safety profiles.Trial numbersClinicalTrials.gov study ID NCT02257385; GSK study no. 116961.

Project description:IntroductionWe report the results of the first direct comparison of the once-daily fixed-dose long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA) combinations umeclidinium/vilanterol (UMEC/VI) and tiotropium/olodaterol (TIO/OLO) in patients with COPD.MethodsThis was a randomized, two-period crossover open-label study in symptomatic patients with COPD [age 40 years or older, postbronchodilator forced expiratory volume in 1 s (FEV1) of 70% or less and 50% or more of predicted normal values, and modified Medical Research Council Dyspnoea Scale score of 2 or greater] not receiving inhaled corticosteroid therapy. Patients were randomized to receive UMEC/VI (62.5/25 µg once daily) via a multidose dry powder inhaler (ELLIPTA) followed by TIO/OLO (5/5 µg once daily) via a soft mist inhaler (Respimat), each for 8 weeks with an interim 3-week washout or vice versa. The primary end point was the change from baseline in trough FEV1 at week 8 with a noninferiority margin of - 50 mL in the per-protocol (PP) population. The incidence of adverse events was also assessed.ResultsIn total, 236 patients (mean age 64.4 years, 60% male) were included in the intent-to-treat population and 227 were included in the PP population. UMEC/VI treatment was noninferior in the PP population and superior in the intent-to-treat population to TIO/OLO treatment with regard to trough FEV1 at week 8 [FEV1 change from baseline 180 mL vs 128 mL; difference 52 mL (95% confidence interval 28-77 mL); p < 0.001]. Patients receiving UMEC/VI had twofold increased odds of experiencing a clinically meaningful increase (100 mL or more) from baseline in trough FEV1 at week 8 compared with patients receiving TIO/OLO (odds ratio 2.05; 95% confidence interval 1.34-3.14). Adverse events occurred in 25% of patients in the UMEC/VI group and in 31% of patients in the TIO/OLO group.ConclusionIn this first direct comparison of two once-daily fixed-dose LAMA/LABA combinations, superiority was observed for the primary end point of trough FEV1 at week 8 with UMEC/VI compared with TIO/OLO in patients with symptomatic COPD. Both treatments had similar safety profiles. These findings confirm the results of previous indirect LAMA/LABA comparisons, and show that an efficacy gradient exists within the LAMA/LABA class.Trial registrationClinicalTrials.gov identifier NCT02799784.FundingGlaxoSmithKline.

Project description:BACKGROUND:Single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62.5/25 ?g has been shown to improve lung function and health status, and reduce exacerbations, versus budesonide/formoterol in patients with chronic obstructive pulmonary disease (COPD). We evaluated the non-inferiority of single-inhaler FF/UMEC/VI versus FF/VI?+?UMEC using two inhalers. METHODS:Eligible patients with COPD (aged ?40 years; ?1 moderate/severe exacerbation in the 12 months before screening) were randomized (1:1; stratified by the number of long-acting bronchodilators [0, 1 or 2] per day during run-in) to receive 24-week FF/UMEC/VI 100/62.5/25 ?g and placebo or FF/VI 100/25 ?g?+?UMEC 62.5 ?g; all treatments/placebo were delivered using the ELLIPTA inhaler once-daily in the morning. Primary endpoint: change from baseline in trough forced expiratory volume in 1 s (FEV1) at Week 24. The non-inferiority margin for the lower 95% confidence limit was set at -?50 mL. RESULTS:A total of 1055 patients (844 [80%] of whom were enrolled on combination maintenance therapy) were randomized to receive FF/UMEC/VI (n?=?527) or FF/VI?+?UMEC (n?=?528). Mean change from baseline in trough FEV1 at Week 24 was 113 mL (95% CI 91, 135) for FF/UMEC/VI and 95 mL (95% CI 72, 117) for FF/VI?+?UMEC; the between-treatment difference of 18 mL (95% CI -13, 50) confirmed FF/UMEC/VI's was considered non-inferior to FF/VI?+?UMEC. At Week 24, the proportion of responders based on St George's Respiratory Questionnaire Total score was 50% (FF/UMEC/VI) and 51% (FF/VI?+?UMEC); the proportion of responders based on the Transitional Dyspnea Index focal score was similar (56% both groups). A similar proportion of patients experienced a moderate/severe exacerbation in the FF/UMEC/VI (24%) and FF/VI?+?UMEC (27%) groups; the hazard ratio for time to first moderate/severe exacerbation with FF/UMEC/VI versus FF/VI?+?UMEC was 0.87 (95% CI 0.68, 1.12). The incidence of adverse events was comparable in both groups (48%); the incidence of serious adverse events was 10% (FF/UMEC/VI) and 11% (FF/VI?+?UMEC). CONCLUSIONS:Single-inhaler triple therapy (FF/UMEC/VI) is non-inferior to two inhalers (FF/VI?+?UMEC) on trough FEV1 change from baseline at 24 weeks. Results were similar on all other measures of efficacy, health-related quality of life, and safety. TRIAL REGISTRATION:GSK study CTT200812; ClinicalTrials.gov NCT02729051 (submitted 31 March 2016).

Project description:BACKGROUND:Prospective evidence is lacking regarding incremental benefits of long-acting dual- versus mono-bronchodilation in improving symptoms and preventing short-term disease worsening/treatment failure in low exacerbation risk patients with chronic obstructive pulmonary disease (COPD) not receiving inhaled corticosteroids. METHODS:The 24-week, double-blind, double-dummy, parallel-group Early MAXimisation of bronchodilation for improving COPD stability (EMAX) trial randomised patients at low exacerbation risk not receiving inhaled corticosteroids, to umeclidinium/vilanterol 62.5/25 μg once-daily, umeclidinium 62.5 μg once-daily or salmeterol 50 μg twice-daily. The primary endpoint was trough forced expiratory volume in 1 s (FEV1) at Week 24. The study was also powered for the secondary endpoint of Transition Dyspnoea Index at Week 24. Other efficacy assessments included spirometry, symptoms, heath status and short-term disease worsening measured by the composite endpoint of clinically important deterioration using three definitions. RESULTS:Change from baseline in trough FEV1 at Week 24 was 66 mL (95% confidence interval [CI]: 43, 89) and 141 mL (95% CI: 118, 164) greater with umeclidinium/vilanterol versus umeclidinium and salmeterol, respectively (both p < 0.001). Umeclidinium/vilanterol demonstrated consistent improvements in Transition Dyspnoea Index versus both monotherapies at Week 24 (vs umeclidinium: 0.37 [95% CI: 0.06, 0.68], p = 0.018; vs salmeterol: 0.45 [95% CI: 0.15, 0.76], p = 0.004) and all other symptom measures at all time points. Regardless of the clinically important deterioration definition considered, umeclidinium/vilanterol significantly reduced the risk of a first clinically important deterioration compared with umeclidinium (by 16-25% [p < 0.01]) and salmeterol (by 26-41% [p < 0.001]). Safety profiles were similar between treatments. CONCLUSIONS:Umeclidinium/vilanterol consistently provides early and sustained improvements in lung function and symptoms and reduces the risk of deterioration/treatment failure versus umeclidinium or salmeterol in symptomatic patients with low exacerbation risk not receiving inhaled corticosteroids. These findings suggest a potential for early use of dual bronchodilators to help optimise therapy in this patient group.
