A Comparative Effectiveness Study of Mortality Outcomes and Related Cardiopulmonary Events Among a Cohort of Chronic Obstructive Pulmonary Disease (COPD) Patients Who Initiate Breztri and Multiple Inhaler Triple Therapy (MITT) in the United States (US)

Patients with chronic obstructive pulmonary disease (COPD) have elevated risk of mortality and cardiopulmonary events, particularly following exacerbations. While single inhaler triple therapies (SITTs), such as budesonide/glycopyrrolate/formoterol fumarate (BGF), reduce mortality and cardiopulmonary event risk versus dual bronchodilator therapy, there is limited evidence comparing outcomes associated with SITTs versus multiple inhaler triple therapies (MITTs). SKOPOS-MAZI was a retrospective comparative effectiveness study in patients with COPD aged ≥40 years using US administrative claims data from Optum's de-identified Clinformatics® Data Mart Database. The primary and secondary endpoints were time to all-cause mortality (ACM) and time to first severe cardiopulmonary event following initiation of BGF or MITT (identification period: October 1, 2020-June 30, 2023; index date: first prescription fill). Relative hazards of outcomes were assessed until a censoring event using Cox proportional hazards models, with inverse propensity treatment weighting accounting for between-group imbalances (standardized mean difference \>0.1) in baseline characteristics.
