Brief summary
This study is a phase III clinical study to assess the efficacy and safety of Revefenacin inhalation solution 175 mcg administered once daily via nebulization for 12 weeks compared to placebo in a population of Chinese subjects with moderate to very severe COPD.
Detailed description
This will be a multi-center, randomized, double blind, placebo-controlled, parallel group study, randomizing approximately 320 male or female moderate-very severe COPD subjects. Subjects will receive study drug for 12 weeks. Treatments to be received during the study will include one of the following, administered using a centrally-provided, standard jet nebulizer and compressor via a mouthpiece: A. Revefenacin inhalation solution 175 mcg Quaque die (QD). B. Placebo inhalation solution QD. Subjects will have approximately 6 clinic visits (encompassing a screening period of up to 30 days and a treatment period of 12 weeks), and a follow-up telephone call 1-2 weeks after the End of Treatment (EoT) visit.
