ABSTRACT
BACKGROUND:
The combination of aclidinium bromide, a long-acting anticholinergic, and formoterol fumarate, a long-acting beta2-agonist (400/12 µg twice daily) achieves improvements in lung function greater than either monotherapy in patients with chronic obstructive pulmonary disease (COPD), and is approved in the European Union as a maintenance treatment. The effect of this combination on symptoms of COPD and exacerbations is less well established. We examined these outcomes in a pre-specified analysis of pooled data from two 24-week, double-blind, parallel-group, active- and placebo-controlled, multicentre, randomised Phase III studies (ACLIFORM and AUGMENT).METHODS:
Patients ≥40 years with moderate to severe COPD (post-bronchodilator forced expiratory volume in 1 s [FEV1]/forced vital capacity <70 % and FEV1 ≥30 % but <80 % predicted normal) were randomised (ACLIFORM 22221; AUGMENT 11111) to twice-daily aclidinium/formoterol 400/12 µg or 400/6 µg, aclidinium 400 µg, formoterol 12 µg or placebo via Genuair™/Pressair®. Dyspnoea (Transition Dyspnoea Index; TDI), daily symptoms (EXAcerbations of Chronic pulmonary disease Tool [EXACT]-Respiratory Symptoms [E-RS] questionnaire), night-time and early-morning symptoms, exacerbations (Healthcare Resource Utilisation [HCRU] and EXACT definitions) and relief-medication use were assessed.RESULTS:
The pooled intent-to-treat population included 3394 patients. Aclidinium/formoterol 400/12 µg significantly improved TDI focal score versus placebo and both monotherapies at Week 24 (all p < 0.05). Over 24 weeks, significant improvements in E-RS total score, overall night-time and early-morning symptom severity and limitation of early-morning activities were observed with aclidinium/formoterol 400/12 µg versus placebo and both monotherapies (all p < 0.05). The rate of moderate or severe HCRU exacerbations was significantly reduced with aclidinium/formoterol 400/12 µg compared with placebo (p < 0.05) but not monotherapies; the rate of EXACT-defined exacerbations was significantly reduced with aclidinium/formoterol 400/12 µg versus placebo (p < 0.01) and aclidinium (p < 0.05). Time to first HCRU or EXACT exacerbation was longer with aclidinium/formoterol 400/12 µg compared with placebo (all p < 0.05) but not the monotherapies. Relief-medication use was reduced with aclidinium/formoterol 400/12 µg versus placebo and aclidinium (p < 0.01).CONCLUSIONS:
Aclidinium/formoterol 400/12 µg significantly improves 24-hour symptom control compared with placebo, aclidinium and formoterol in patients with moderate to severe COPD. Furthermore, aclidinium/formoterol 400/12 µg reduces the frequency of exacerbations compared with placebo. TRIAL REGISTRATION NCT01462942 and NCT01437397 (ClinicalTrials.gov).
