Patients were randomised 1:1 to umeclidinium 62.5 µg or glycopyrronium 50 µg administered via Ellipta or Breezhaler dry powder inhaler, respectively. The primary endpoint was trough forced expiratory volume in 1 s (FEV1) at day 85 in the per-protocol population. Other endpoints included: weighted mean FEV1 over 0–24 h and patient-reported outcomes (transition dyspnoea index score and St George's Respiratory Questionnaire total score). Adverse events were also assessed.A total of 1037 patients were randomised to treatment. Umeclidinium was non-inferior (margin: −50 mL) to glycopyrronium (trough FEV1 at day 85 treatment difference: 24 mL, 95% confidence intervals: −5–54). Improvements in other endpoints were similar between treatments. Adverse event incidences were similar for umeclidinium (37%) and glycopyrronium (36%).Once-daily umeclidinium was non-inferior to once-daily glycopyrronium in patients with chronic obstructive pulmonary disease in trough FEV1 at day 85. Patient-reported outcomes and safety profiles were similar for both treatments.Once-daily umeclidinium is non-inferior to once-daily glycopyrronium in patients with COPD by trough FEV1 at day 85 http://ow.ly/4mRdE6 ER -
