Efficacy of aclidinium/formoterol 400/12 µg, analyzed by airflow obstruction severity, age, sex, and exacerbation history: pooled analysis of ACLIFORM and AUGMENT.

ABSTRACT:

Background

Aclidinium/formoterol 400/12 µg is a twice-daily maintenance bronchodilator for COPD. This post hoc study evaluated aclidinium/formoterol vs aclidinium 400 µg, formoterol 12 µg, or placebo in patient subgroups.

Patients and methods

Data were pooled from two 24-week Phase III clinical trials (ACLIFORM and AUGMENT). Patients (N=3,394) were analyzed by baseline airflow obstruction severity (moderate/severe), age (<65/≥65 years), sex, and exacerbation history (0/≥1 exacerbation in the previous 12 months). Changes from baseline vs placebo and mono-therapies were evaluated: morning pre-dose (trough) and morning 1-hour post-dose FEV₁, Transition Dyspnea Index (TDI), and moderate/severe exacerbation rates (healthcare resource utilization [HCRU] and EXAcerbation
