Background: A secondary analysis of pooled data, stratified by concomitant inhaled corticosteroid (ICS) use, is presented from ACLIFORM (NCT01462942) and AUGMENT (NCT01437397), two Phase III, 24-week, randomised, double-blind studies of twice-daily (BID) aclidinium/formoterol (AB/FF) fixed-dose combination in patients (pts) with moderate to severe airflow obstruction.

Methods: Pts received BID AB/FF 400/12 µg, AB/FF 400/6 µg, AB 400 µg, FF 12 µg or placebo (PB). Assessments: change from baseline in 1-hour morning post-dose and morning pre-dose (trough) forced expiratory volume in 1 second (FEV1) at Week 24, Transition Dyspnoea Index (TDI) score (pre-planned), exacerbation rate and adverse events (AEs).

Results: Analyses included 3398 pts (mean age 63.5 years; 60.5% male; baseline ICS use range 38.7 – 40.0%). AB/FF 400/12 µg with ICS improved post-dose FEV1, trough FEV1 (Table), and TDI vs. PB by 297 mL, 145 mL and 1.59 units, respectively (all p < 0.001). In addition, AB/FF 400/12 µg with ICS improved post-dose FEV1 and trough FEV1 (Table) by 109 mL and 71 mL, respectively, vs. FF alone (both p < 0.001) and by 151 mL and 54 mL, respectively, vs. AB alone (p < 0.001 and p < 0.05, respectively). AB/FF 400/12 µg without ICS improved post-dose FEV1, trough FEV1 (Table) and TDI by 290 mL, 135 mL and 1.36 units vs. PB, respectively (all p < 0.001). Exacerbation rates were higher with ICS (0.67) vs. without (0.36); AB/FF 400/12 µg significantly reduced exacerbations vs. PB in ICS users (p < 0.05; Table). AE frequency was similar throughout (range with ICS, 54.8 – 60.7%; without, 56.0 – 60.3%). Most common AEs across pt groups were COPD exacerbation, nasopharyngitis and headache, regardless of ICS use.

Conclusion: AB/FF 400/12 µg BID improved bronchodilation and dyspnoea regardless of ICS use and reduced exacerbations in pts using ICS. AE frequency was similar across pt groups, regardless of ICS use.
