Efficacy and Safety of NVA237 in Patients With Chronic Obstructive Pulmonary Disease (COPD)

Forced Expiratory Volume in one second (FEV1) is calculated as the volume of air forcibly exhaled in one second as measured by a spirometer.

FEV1 was measured between dosing regimens (over the range 20 micrograms to 55 micrograms total daily dose) after 28 days of treatment.

Mean trough FEV1 was measured in response to all doses administered (12.5 µg q.d., 25.0 µg q.d., 12.5 µg b.i.d., 50 µg q.d., 25 µg b.i.d., 100 µg q.d., 50.0 µg b.i.d., and Placebo; see Outcome Measure # 19), and was used to compute modeled dose-response curves for once-daily and twice-daily regimens separately. The difference between those curves was computed at pre-specified theoretical doses (20 µg, 25 µg, 30 µg, 35 µg, 40 µg, 45 µg, 50 µg, and 55 µg) chosen at points likely to show the largest differences between the once-daily and twice-daily regimens. The theoretical responses to each dosing schedule separately and the difference between the once-daily and twice-daily regimens are represented below.
