Abstract

Introduction: Previously, adherence and persistence to treatment have been shown to improve outcomes among patients with chronic obstructive pulmonary disease (COPD). This study aimed to evaluate adherence and persistence to single-inhaler triple therapy with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI; one inhalation, once-daily) compared with budesonide/glycopyrrolate/formoterol fumarate (BUD/GLY/FOR; two inhalations, twice-daily) among patients with COPD in the USA.

Methods: This retrospective weighted cohort study used claims data from the IQVIA PharMetrics^® Plus Database from October 1, 2019 to March 31, 2023, to identify patients with COPD newly initiating FF/UMEC/VI or BUD/GLY/FOR. Index date was the first pharmacy claim for FF/UMEC/VI or BUD/GLY/FOR on or after October 1, 2020. The longest follow-up period was 12 months. Inverse probability of treatment weighting was used to balance baseline characteristics between cohorts. Adherence was measured as mean proportion of days covered (PDC); the proportion of patients with PDC ≥ 0.5 and PDC ≥ 0.8 was also assessed. Persistence was assessed as time to treatment discontinuation using Kaplan-Meier rates.

Results: Overall, 8912 and 2685 patients were included in the FF/UMEC/VI and BUD/GLY/FOR cohorts, respectively. After weighting, mean age and proportion of patients with Medicare Advantage insurance was 64.62 years and 40.0% in the FF/UMEC/VI cohort and 63.96 years and 36.1% in the BUD/GLY/FOR cohort. At 6 months post-index, mean PDC was greater in the FF/UMEC/VI versus the BUD/GLY/FOR cohort (0.65 versus 0.59; P < 0.001). A significantly greater proportion of patients in the FF/UMEC/VI versus the BUD/GLY/FOR cohort had PDC ≥ 0.8 (45.6% versus 34.5%; P < 0.001) and PDC ≥ 0.5 (71.8% versus 64.3%; P < 0.001). Results were consistent at 12 months post-index. When a 30-day gap was used to define treatment discontinuation, the FF/UMEC/VI cohort had statistically significantly greater treatment persistence versus the BUD/GLY/FOR cohort at all time points.

Conclusion: In this study, patients initiating FF/UMEC/VI had significantly greater adherence and persistence to treatment than patients initiating BUD/GLY/FOR.

期刊介绍： Advances in Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged. The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Advances in Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
