Patient and Clinical Demographics of New Users to Single-Inhaler Triple Therapy in Patients with Chronic Obstructive Pulmonary Disease.

INTRODUCTION: Single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) triple therapy was approved by the United States Food and Drug Administration in 2017 as a maintenance therapy for chronic obstructive pulmonary disease (COPD). Patient characteristics and treatment patterns prior to initiating FF/UMEC/VI are currently unknown. This study assessed patient characteristics, exacerbation, and medication history in patients with COPD before the initiation of FF/UMEC/VI or multiple-inhaler triple therapy (MITT). METHODS: This was a retrospective study using the Optum Clinformatics® Data Mart. Patients who initiated FF/UMEC/VI triple therapy or MITT (consisting of a long-acting muscarinic antagonist [LAMA], long-acting ß2-agonist [LABA], and inhaled corticosteroid [ICS]) between October 2017 and September 2018, were enrolled in commercial or Medicare Advantage Prescription Drug plans, were aged > 40 years, and had a COPD diagnosis were eligible. Patient characteristics, comorbidities, COPD medication use, exacerbations, and eosinophil counts were assessed in the 12-month baseline period prior to initiation of FF/UMEC/VI triple therapy or MITT. RESULTS: The study population included 3933 FF/UMEC/VI users and 18,244 MITT users. Mean (standard deviation) patient age was 72.2 (8.6) years in FF/UMEC/VI users and 70.7 (9.7) years in MITT users. Prior to initiating triple therapy, the majority of FF/UMEC/VI (89.1%) and MITT (93.8%) users experienced a moderate or severe exacerbation or used a COPD maintenance therapy during the baseline period. In addition, 41.2% of FF/UMEC/VI users received overlapping ICS/LAMA/LABA, 20.3% received ICS/LABA, and 9.7% received LAMA/LABA. CONCLUSION: In this population of COPD patients, triple therapy was frequently initiated after previous maintenance medication use or an exacerbation, in line with treatment guideline recommendations.

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.

Once-daily single-inhaler versus twice-daily multiple-inhaler triple therapy in patients with COPD: lung function and health status results from two replicate randomized controlled trials.

BACKGROUND: The comparative efficacy of inhaled corticosteroid/long-acting muscarinic antagonist/long-acting ß2-agonist (ICS/LAMA/LABA) triple therapy administered via single or multiple inhalers in patients with chronic obstructive pulmonary disease (COPD) has not been evaluated comprehensively. We conducted two replicate trials comparing single- with multiple-inhaler ICS/LAMA/LABA combination in COPD. METHODS: 207608 and 207609 were Phase IV, 12-week, randomized, double-blind, triple-dummy non-inferiority trials comparing once-daily fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62.5/25 µg via Ellipta inhaler, with twice-daily budesonide/formoterol (BUD/FOR) 400/12 µg via metered-dose inhaler plus once-daily tiotropium (TIO) 18 µg via HandiHaler. Patients had symptomatic COPD and forced expiratory volume in 1 s (FEV1) < 50% predicted, or FEV1 < 80% predicted and ≥ 2 moderate or 1 severe exacerbations in the prior year. The primary endpoint in both trials was weighted mean change from baseline (wmCFB) in 0-24-h FEV1 at Week 12. Secondary endpoints included CFB in trough FEV1 at Day 84 and 85. Other endpoints included serial FEV1 and health status outcomes at Week 12. Safety was evaluated descriptively. RESULTS: The modified per-protocol population included 720 and 711 patients in studies 207608 and 207609 (intent-to-treat population: 728 and 732). FF/UMEC/VI was non-inferior to BUD/FOR+TIO for wmCFB in 0-24-h FEV1 at Week 12 (Study 207608 treatment difference [95% confidence interval]: 15 mL [- 13, 43]; Study 207609: 11 mL [- 20, 41]). FF/UMEC/VI improved trough FEV1 CFB versus BUD/FOR+TIO at Day 84 and 85 (Day 85 treatment difference: Study 207608: 38 mL [10, 66]; Study 207609: 51 mL [21, 82]) and FEV1 at 12 and 24 h post-morning dose at Week 12 in both studies. No treatment differences were seen in health status outcomes. Safety profiles were similar between treatments; pneumonia occurred in 7 (< 1%) patients with FF/UMEC/VI and 9 (1%) patients with BUD/FOR+TIO, across both studies. CONCLUSIONS: FF/UMEC/VI was non-inferior to BUD/FOR+TIO for wmCFB in 0-24-h FEV1 at Week 12 in patients with COPD. Greater improvements in trough and serial FEV1 measurements at Week 12 with FF/UMEC/VI versus BUD/FOR+TIO, together with similar health status improvements and safety outcomes including the incidence of pneumonia, suggest that once-daily single-inhaler FF/UMEC/VI triple therapy is a viable option for patients looking to simplify their treatment regimen.
