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 β2-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.
