Results include trough forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) at Day 1 and Wks 12, 26 and 52, 24-hr serial spirometry in a subset of patients, and FEV1 AUC.Results1888 subjects were randomized, 98.2% analyzed (NVA237=1059, TIO=267, PBO=528); male: 71.5%, mean age: 63.9yr, mean post-bronchodilator FEV1: 55.5% predicted. All trough FEV1 and FVC values for NVA237 and TIO were significantly greater than PBO (p<0.001) and NVA237 was numerically higher than TIO at all-time points (Table).View this table:Table: Trough FEV1 and FVC least square mean treatment difference (SE) from PBO (mL)The improvement in FEV1 with NVA237 was seen immediately after the first dose on Day 1 (90mL at 5min and 144mL at 15min versus PBO, p<0.001) and sustained throughout the 52 Wk period. FEV1 AUC for 0-4h, 0-12h, 0-24h and 12-24h for NVA237 was significantly greater than PBO (p<0.05) and numerically greater than TIO on Day 1, Wk 12, 26 and 52.ConclusionNVA237 50μg QD provided rapid, sustained and clinically meaningful bronchodilation over 52 wks with efficacy similar to tiotropium.
