Abstract
Despite fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) being available for asthma treatment in the US (United states) since 2020, real-world evidence on its clinical and economic benefits in patients with asthma is lacking. This study aimed to assess the effectiveness of FF/UMEC/VI (100/62.5/25 µg and 200/62.5/25 µg) in US patients with asthma previously on inhaled corticosteroid/long-acting β 2 -agonists (ICS/LABA) using administrative claims data. Retrospective, longitudinal, pre-post study utilizing data from the Komodo Health database between 09/09/2019 and 12/31/2023. Eligible adults with asthma had been treated with ICS/LABA prior to FF/UMEC/VI initiation (index date: first FF/UMEC/VI prescription). Rates of moderate–severe exacerbations, asthma-related healthcare resource utilization, oral corticosteroid (OCS) and short-acting β 2 -agonist (SABA) use, and asthma-related medical costs were evaluated pre- (12 months pre-index) and post-FF/UMEC/VI initiation (12 months post-index). Statistical analyses involved rate ratios (RRs) from a Poisson regression model, odds ratios (ORs) from logistic regression models, and mean differences from linear regression models. Exploratory analyses stratified these results by pre-index ICS/LABA combination and FF/UMEC/VI index dose. In total, 17,959 patients were included. Following FF/UMEC/VI initiation, odds of having ≥ 1 exacerbation were reduced by 52% (OR [95% confidence interval (CI)] 0.48 [0.46, 0.50]; P < 0.001), rate of moderate–severe exacerbations reduced by 38% (RR [95% CI] 0.62 [0.61, 0.64]; P < 0.001) and asthma-related hospitalizations by 25% (RR [95% CI] 0.75 [0.68, 0.83]; P < 0.001). Odds of ≥ 1 OCS dispensing were reduced by 36% (OR [95% CI] 0.64 [0.62, 0.67]; P < 0.001) and ≥ 1 SABA canister use by 54% (OR [95% CI]: 0.46 [0.44, 0.48]; P < 0.001) post initiation; mean annualized asthma-related medical costs were reduced by $1115 ([95% CI] [$ −1771, $ −459]; P < 0.001). Both FF/UMEC/VI dosage groups had similar results. In patients who remain uncontrolled despite ICS/LABA treatment, escalating to FF/UMEC/VI is associated with reductions in asthma exacerbations, asthma-related hospitalizations, OCS use, SABA use, and asthma-related medical costs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
