About

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.

Inclusion criteria

1 initial prescription for BGF or MITT starting October 1, 2020 through to the latest available data update, AND
- Age ≥40 years on date of first prescription for BGF or MITT episode, AND
- Continuous medical and pharmacy health plan eligibility for ≥12-months (365 days) prior to first prescription for BGF or MITT AND
2 medical claims with diagnoses for COPD at least 30 days apart occurring on or anytime in the patient's available 24-month history before the first BGF prescription or MITT episode, with one diagnosis occurring in the immediate 12-month period prior to or on initiation of BGF or MITT

Exclusion criteria

Age <40 at time of treatment initiation
Invalid or unknown gender
If death date occurs prior to or on study index date
<12 months (365 days) of medical and pharmacy health plan eligibility/coverage prior treatment initiation
Presence of ≥1 prescription claim for any triple therapy during the patient's entire available baseline history (BGF, FF/UMEC/VI or MITT)
"potential MITT use" in baseline, MITT for baseline purposes will be defined as ≥1 days continuous days where all three MITT components (ICS, LABA, LAMA) are observed in combination (dual + monotherapy) or as three separate monotherapy components
History of any of the following conditions, procedures or events during the immediate baseline 12-month period: (a) ≥1 medical claim (i.e., office, ED or hospital) in any position with a diagnosis for alpha-1-antitrypsin deficiency, interstitial fibrosis, lung cancer, pulmonary embolism, sarcoidosis; (b) ≥1 medical claim for hospice services; (c) Any medical Bill Type Code (BILL_TYPE_CODE ) starting with 81 or 82; or Revenue codes (RVNU_CD): 0651-0659; (d) ≥1 medical claim with a diagnosis code of encounter related to clinical trial participation (Z00.6) at any point during the study period (including both baseline and follow-up periods)
