"Extrafine single inhaler triple therapy effect on health status, lung function and adherence in COPD patients: A...

The extrafine single inhaler triple therapy (efSITT) containing beclometasone dipropionate/formoterol fumarate/glycopyrronium 87/5/9 μg has proved to be efficacious in patients with Chronic Obstructive Pulmonary Disease (COPD) in randomized control trials. TRIBUNE study aimed to assess the efSITT effectiveness on health status, lung function, adherence and rescue medication use in COPD patients in Greece in a real-world setting. This was a 24-week prospective, multicenter, observational study in 1,195 patients with moderate/severe COPD and history of at least one exacerbation during the previous year despite dual therapy. Health status (COPD Assessment Test/CAT), lung function parameters and rescue medication use were recorded at baseline, 3 (Visit 2/V2) and 6 months (Visit 3/V3) after treatment. Adherence (Test of Adherence to Inhalers/TAI) and self-reported overall impression of health condition change (Visual Analogue Scale/VAS) were recorded at V2 and V3. Mean CAT score decreased from 20.9 points at V1, to 15.1 at V2 and 13 at V3 (p < 0.001, all pair comparisons). 85.9% of patients achieved a CAT decrease of minimal clinically important difference (MCID) or more (≥2) at V3, compared to V1. Mean FEV1 increased from 1.4 ± 0.5 L on V1, to 1.6 ± 0.5 L on V3 (p < 0.001, N = 275). The percentage of patients with "good adherence" increased from 58.4% (V2) to 64.0% (V3). Rescue medication use and VAS also significantly improved. The efSITT achieves improved outcomes on health status, lung function and rescue medication use as well as satisfactory adherence and patient-reported improvement of health condition, in moderate/severe COPD patients previously treated with a dual combination in a Greek real-world setting.
