PURPOSE: Treatment guidelines for chronic obstructive pulmonary disease (COPD) recommend combination therapy of 2 or more long-acting bronchodilators with different mechanisms of action. Here we report the long-term safety of a fixed-dose combination of aclidinium bromide, a long-acting muscarinic antagonist indicated for maintenance treatment of COPD-associated bronchospasm, with formoterol fumarate, a long-acting β2-agonist, in patients with COPD.

METHODS: In this phase 3, double-blind, parallel-group, active-controlled study, patients with moderate to severe COPD were randomized 2:1 to twice-daily (BID) aclidinium 400 µg/formoterol 12 µg (FDC 400/12) or formoterol 12 µg alone for 52 weeks, both administered via a multidose dry powder inhaler (Genuair®/Pressair®). Safety and tolerability were assessed via adverse events (AEs).

RESULTS: A total of 590 patients were randomized, all of whom were included in the safety population. In this study (FDC 400/12, n=392; formoterol, n=198), patients had a mean baseline forced expiratory volume in 1 second (FEV1) of 1.3 L and postbronchodilator FEV1 % predicted of 51.3%. A similar percentage of patients who received FDC 400/12 or formoterol completed the study (67.6% and 67.2%, respectively), with AEs leading to study discontinuation reported by similar proportions of patients (6.6% and 7.1%, respectively). AEs were reported by 280 (71.4%) and 130 (65.7%) patients in the FDC 400/12 and formoterol groups, respectively. The most commonly reported AEs (ie, ≥5% in both FDC 400/12 and formoterol) were urinary tract infection (6.6% and 5.6%, respectively) and sinusitis (5.1% and 5.6%, respectively). Serious AEs (SAEs) were reported by a similar proportion of patients treated with FDC 400/12 (n=38 [9.7%]) or formoterol (n=21 [10.6%]). Pneumonia was the most frequently reported SAE, occurring in 4 patients (1.0%) and 1 patient (0.5%) in the FDC 400/12 and formoterol groups, respectively. On-therapy deaths occurred in 5 (1.3%) patients with FDC 400/12 (sudden cardiac death etiology unknown, n=2; suicide, metastatic lung cancer, cardiopulmonary arrest, n=1 each) and 1 (0.5%) patient with formoterol (COPD exacerbation).

CONCLUSIONS: Long-term treatment with a twice-daily fixed-dose combination of aclidinium/formoterol was well tolerated in patients with COPD, with an AE profile generally similar to that of formoterol alone.

CLINICAL IMPLICATIONS: Aclidinium/formoterol fixed-dose combination may be a safe therapeutic option in patients with moderate to severe COPD.

Aclidinium bromide (Tudorzo/Pressair, Eklira/Genuair, Breo/Ellipta) is approved for the maintenance treatment of COPD-associated bronchspasm. The fixed-dose combination of aclidinium bromide/formoterol fumarate is being developed, but not yet approved, for its commercial use for the treatment of COPD.
