Here, we investigate whether the safety and efficacy of aclidinium bromide differ due to exacerbation history in patients with COPD and increased cardiovascular risk.Patients and Methods: ASCENT-COPD was a Phase 4, multicenter, double-blind, randomized, placebo-controlled, parallel-group study of patients with moderate-to-very severe COPD and increased cardiovascular risk. Patients were randomized 1:1 to receive aclidinium or placebo twice daily for up to 3 years. Outcomes included time to first MACE and all-cause mortality over 3 years, exacerbation rate during the first year on-treatment, and change in baseline pre-dose forced expiratory volume in 1 second (FEV1) over 3 years. This pre-specified subgroup analysis compared outcomes in patients receiving aclidinium vs placebo. The comparison of patients with vs without an exacerbation history was added following a protocol amendment to increase enrollment in the primary study.Results: Of 3589 patients, 2156 (60.1%) had ≥ 1 moderate or severe exacerbations in the prior year, ...
