Introduction
Few studies have utilized 24-h serial spirometry to compare the effects of inhaled chronic obstructive pulmonary disease (COPD) therapies on lung function. The FULFIL study previously reported significant lung function improvements with once-daily single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus twice-daily single-inhaler budesonide/formoterol (BUD/FOR) in patients with symptomatic COPD at risk of exacerbations.
Methods
This prespecified analysis evaluated 24-h serial spirometry data from a subgroup of 406 patients in FULFIL. BUD/FOR twice-daily dosing was maintained during 24-h spirometry. A post hoc analysis evaluated serial forced expiratory volume in 1 s (FEV1) at day 1 and week 24 by disease severity at screening (FEV1 < 50% predicted and no moderate or severe exacerbation in prior year, FEV1 < 50% predicted and ≥ 1 moderate or severe exacerbation in prior year, and FEV1 ≥ 50% and < 80% predicted and ≥ 2 moderate or ≥ 1 severe exacerbations in prior year).
Results
Odds of achieving a ≥ 100-mL increase from baseline in FEV1 within the first 6 h post dose on day 1 were significantly greater with FF/UMEC/VI than BUD/FOR [odds ratio 2.79 (95% confidence interval 1.56–4.98); p < 0.001]. FF/UMEC/VI led to greater improvements in weighted mean FEV1 over 0–6, 0–12, 0–24, and 12–24 h on day 1 and at week 24, with the greatest between-group differences at week 24 (range 196–210 mL; all p < 0.001). Significant between-treatment differences in FEV1 and forced vital capacity (FVC) in favor of FF/UMEC/VI versus BUD/FOR were seen at all time points at week 24 (FEV1 range 156–231 mL, all p < 0.001; FVC range 139–309 mL, all p ≤ 0.002). Serial FEV1 results were consistent irrespective of disease severity at screening.
Conclusion
These findings further demonstrate sustained lung function benefits with once-daily FF/UMEC/VI single-inhaler triple therapy in patients with symptomatic COPD at risk of exacerbations across a range of disease severities.
