Healthy volunteers: no

Brief summary:
The purpose of this study is to evaluate the dose-response of 4 doses of umeclidinium bromide in combination with fluticasone furoate compared with fluticasone furoate monotherapy in chronic obstructive pulmonary disease participants with an asthmatic component. The fluticasone furoate/umeclidinium bromide treatments will also be compared to the once-daily inhaled corticosteroid/long-acting beta agonist combination fluticasone furoate/vilanterol.

Detailed description:

Arms:
arm 1: Eligible subjects will enter a 4-week run-in period and will receive fluticasone propionate/salmeterol. Subjects will then be randomized to receive fluticasone furoate 100 mcg, fluticasone furoate/umeclidinium bromide 100/15.6 mcg, fluticasone furoate/umeclidinium bromide 100/62.5 mcg, fluticasone furoate/umeclidinium bromide 100/125 mcg, fluticasone furoate/umeclidinium bromide 100/250 mcg, or fluticasone furoate/vilanterol 100/25 mcg, respectively for 4 weeks arm 2: Subjects completing Treatment Phase A will be randomized to receive either fluticasone furoate/umeclidinium bromide100/250 mcg or fluticasone furoate/umeclidinium bromide/vilanterol 100/250/25 mcg for 1 week. arm 3: Subjects completing Treatment Phase B will be randomized to receive either the same treatment as in Treatment Phase B, or the same treatment minus the umeclidinium bromide component, for 1 week.
