Primary Outcome Measures:

AUC(0-6) FEV1 (Area under the curve of change in FEV1 from baseline to 6 hours post dose) [ Time Frame: after 12 weeks of treatment ]

Secondary Outcome Measures:

Forced vital capacity (FVC) [ Time Frame: 12 weeks ]
Peak expiratory flow rate (PEFR) [ Time Frame: 12 weeks ]
Use of rescue medication [ Time Frame: 12 weeks ]
AUC0-6hFEV1 [ Time Frame: after first dose on Day 1 and after 4 weeks of treatment ]
Change in trough FEV1 (i.e. trough response) from baseline. [ Time Frame: after 4 and 12 weeks of treatment ]
Change in peak FEV1 from baseline (=peak response) after first dose [ Time Frame: after 4 and 12 weeks of treatment ]
AUC0-6hFVC defined in the same way as for FEV1. [ Time Frame: Day 1, week 4 ]
Trough FVC defined in the same way as for FEV1. [ Time Frame: Day 1, week 4 ]
Peak FVC defined in the same way as for FEV1 [ Time Frame: Day 1, week 4 ]
Weekly average PEFR in the morning (a.m. pre-dose measurement) and in the evening (p.m. measurement). [ Time Frame: 12 weeks ]
Weekly average number of puffs of rescue medication used [ Time Frame: 12 weeks ]
Occurrence of adverse events [ Time Frame: 12 weeks ]
Change from baseline in pulse rate and systolic and diastolic blood pressure (seated) measured just before spirometry [ Time Frame: 12 weeks ]
Change from baseline in Physical examination [ Time Frame: 12 weeks ]
