Characteristics of Patients with COPD Initiating Budesonide/Glycopyrronium/Formoterol or Other Triple Therapies in Japan: A Real-World Healthcare Claims Database Study (MITOS-AURA).

INTRODUCTION: In Japan, patients with chronic obstructive pulmonary disease (COPD) can be escalated to treatment with inhaled triple therapy. Two single-inhaler triple therapies combining an inhaled corticosteroid/long-acting muscarinic antagonist/long-acting β2-agonist (ICS/LAMA/LABA) are approved maintenance therapies for patients with COPD, and multiple-inhaler triple therapies (MITTs) are also available. There is limited evidence regarding real-life treatment patterns and characteristics of patients with COPD initiating triple therapies.

METHODS: This observational, retrospective cohort study identified patients with COPD in Japan from an administrative claims database (May 2018-December 2021). Demographics, clinical characteristics, and healthcare resource utilization (HCRU) were assessed in four cohorts initiating a triple therapy: budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF) early adopters (initiated ≤ 12 months after market approval [September 1, 2019]), contemporary BGF users (initiated > 12 months after market approval), fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) users, and any MITT users.

RESULTS: A total of 636 patients were BGF early adopters, 2558 were contemporary BGF users, 11,187 used FF/UMEC/VI, and 5931 used MITT. The percentage of patients with concomitant asthma in each cohort was 73.0%, BGF early adopter; 74.2%, contemporary BGF; 75.7%, FF/UMEC/VI; and 84.5%, MITT. During the 12-month baseline period, the frequency of patients with ≥ 1 moderate/severe exacerbation was 18.2%, BGF early adopter; 14.3%, contemporary BGF; 13.1%, FF/UMEC/VI; and 14.0%, MITT. ICS/LABA treatment during baseline was the most frequent pathway to triple therapy, ranging from 38.2% to 51.7% across cohorts. HCRU was relatively high across cohorts (range of hospital outpatient visits/patient during the 12-month baseline period, 11.0-14.1). Multimorbidity was observed in > 80% of patients in all cohorts; cardiovascular diseases were among the most common.

CONCLUSION: Many patients initiating triple therapy for COPD had concomitant asthma and had previously received ICS/LABA maintenance therapy. Patients prescribed BGF in the initial post-launch period were more likely to have a previous exacerbation history versus other cohorts, indicating more severe disease.
