Dataset from 201546, A Repeat-dose Study of Batefenterol/FF (GSK961081/GW685698) Compared With Placebo in the Treatment of COPD

Batefenterol inhalation powder is currently under development as a fixed-dose combination with fluticasone furoate (FF) for the treatment of Chronic Obstructive Pulmonary Disease (COPD). The present study will administer batefenterol/FF (300/100 micrograms [mcg]) for the first time to subjects with COPD, to investigate the safety and tolerability of the combination compared with placebo, and to evaluate the pharmacokinetics and pharmacodynamics profiles of the individual components when administered in combination. This is a Phase IIa, multicenter, randomized, placebo-controlled, double-blind, parallel group study. Subjects will be randomized (2:1) to one of the following double-blind treatment groups: Batefenterol/FF 300/100 mcg inhalation powder once daily, or matching placebo inhalation powder once daily. Subjects will self-administer the study treatments once daily (QD) in the morning for 42 days via a multi-dose dry powder inhaler (DPI) which contains two blister strips. Additionally, an inhaled short acting beta2-receptor agonist, albuterol will be provided from screening to the end of the treatment period for all subjects to use as needed to relieve COPD symptoms. At the end of the treatment period, subjects can resume conventional therapy. The study will randomize approximately 60 subjects. The total duration of subject participation (from screening to follow-up) will be approximately 8 weeks.
