Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multicenter, randomized, double-blind, placebo-controlled, 2-period, complete block design cross-over study.

The purpose of this study is to evaluate the effect of UMEC/VI 62.5/25 microgram (mcg) on EET as measured by the Endurance Shuttle Walk Test (ESWT) compared to placebo. Additionally, the effect of UMEC/VI compared to placebo on lung function and lung volumes in COPD patients will be characterized.

Approximately 298 participants will be screened and, assuming 35% of these will not be eligible for randomization; approximately 194 participants will be randomized.

Eligible participants will be randomized 1:1 to one of 2 treatment sequences. In sequence 1 participants will receive UMEC/VI 62.5/25 mcg in Treatment Period 1 and placebo in Treatment Period 2. In sequence 2 participants will receive placebo in Treatment Period 1 and UMEC/VI 62.5/25 mcg in Treatment Period 2. Treatments will be delivered once-daily via a dry powder inhaler (DPI). Each treatment period will be for 12 weeks and will be separated by a wash out period of 12-17 days. The total duration of patient participation, including the Follow-Up will be approximately 30 weeks. All participants will be provided with albuterol for use on an "as needed (prn)" basis throughout the run-in, washout and study treatment periods while on investigational product.
