Study 2: lung function (forced expiratory volume in 1 s (FEV1)) on day 3. a) FEV1 change from baseline (pre-dose on day 1). b) Peak FEV1 change from baseline (pre-dose on day 1) caused by tiotropium (18 µg), tiotropium (18 µg)+RPL554 (1.5 mg) and tiotropium (18 µg)+RPL554 (6 mg). c) Average FEV1(0–12 h) change from baseline (pre-dose on day 1) caused by tiotropium (18 µg), tiotropium (18 µg)+RPL554 (1.5 mg) and tiotropium (18 µg)+RPL554 (6 mg). Data are presented as mean±sem. **: p<0.01.
