AbstractThe defining feature of chronic obstructive pulmonary disease (COPD) is progressive airflow limitation that causes air trapping and hyperinflation. The increasing hyperinflation results in dyspnea along with associated inability to engage in the activities of daily living. The American Thoracic Society (ATS), European Respiratory Society (ERS) and Global Initiative for Chronic Obstructive Lung Disease (GOLD) treatment guidelines all place bronchodilators as the foundation of pharmacological management of COPD. In patients with moderate-to-very-severe respiratory impairment, adding regular treatment with one or more long-acting bronchodilators is recommended [long-acting β2-agonists (LABAs) or long-acting muscarinic antagonists (LAMAs)]. A growing body of evidence shows that LAMA and LABA co-administration is more effective than either drug class alone in managing stable COPD to improve lung function, symptoms and health status. Recently, new drug applications (NDAs) for a fixed-dose combination (FDC) of umeclidinium (UMEC), a LAMA, and vilanterol (VI), a LABA, at UMEC/VI doses of 125/25 and 62.5/25 µg have been submitted by sponsors to the US Food and Drug Administration (FDA) and to the European Medicines Agency (EMA). Thus, UMEC/VI has become the first FDC LAMA/LABA product that has reached a regulatory approval stage. Other LAMA/LABA once-daily combinations coming through development include FDCs of tiotropium and olodaterol, glycopyrronium and indacaterol, and twice-daily aclidinium and formoterol. The aim of this review is to explore currently available data for once-daily UMEC/VI in the context of the evolving standards of COPD management.
