Background:
Real-world evidence of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) use in Japan is limited. This real-world study assessed adherence to FF/UMEC/VI once-daily single-inhaler triple therapy (SITT) versus multiple-inhaler triple therapy (MITT) among patients with asthma in Japan.
Methods:
Retrospective observational cohort study of patients with asthma initiating FF/UMEC/VI SITT or MITT, using claims data (02/18/2021-02/28/2022, JMDC database). Patients were aged ≥15 years at index (date of FF/UMEC/VI or MITT claim). Outcomes were assessed in two cohorts and weighted using inverse probability of treatment weighting: 1) 'overall cohort' included patients who received FF/UMEC/VI or MITT as initial maintenance therapy (IMT) or as non-IMT (i.e., had previously received inhaled corticosteroid-containing medication during baseline); 2) 'non-IMT cohort' was a sub-cohort of the overall cohort.
Primary Outcome:
proportion of adherent patients (proportion of days covered ≥0.8) in the 3, 6, and 12 months after, and including, index date.
Results:
The overall cohort comprised 7228 (FF/UMEC/VI) and 864 (MITT) patients. Of these, 3623 and 735 were included in the FF/UMEC/VI and MITT non-IMT cohort, respectively. At 3 months post-index, a significantly higher proportion of patients were adherent to FF/UMEC/VI (36.4 % [n = 2631]) versus MITT (31.2 % [n = 270]) in the overall cohort (rate ratio [95 % confidence interval], 1.16 [1.05-1.29], p = 0.003, weighted), and FF/UMEC/VI (36.6 % [n = 1326]) versus MITT (28.9 % [n = 213]) in the non-IMT cohort (1.26 [1.12-1.43], p < 0.001). Similar results were observed at 6, and 12 months post-index.
Conclusions:
Patients with asthma in Japan who initiated FF/UMEC/VI SITT had significantly better treatment adherence than those who initiated MITT.

Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
