Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Comparison of trough FEV1 values at the end of 4-week treatment with tiotropium inhalation solution (5 mcg, 10 mcg) to that achieved with tiotropium inhalation powder (Spiriva 18 mcg). | — |
Secondary
| Measure | Time frame |
|---|---|
| Peak response (FEV1 and FVC) to first dose | within 3 hours to first dose |
| Peak response (FEV1 and FVC) after 4 weeks | within 3 hours after 4 weeks |
| FEV1 AUC0-12h and FVC AUC0-12h response after 4 weeks | after 4 weeks |
| FEV1 AUC0-3h and FVC AUC0-3h response after the first dose and after 4 weeks | after first dose and after 4 weeks |
| Individual FEV1and FVC measurements at each time point | up to 28 weeks |
| Trough forced vital capacity (FVC) response after 4 weeks (change from baseline) | baseline until week 28 |
| Number of occasions of rescue therapy used as required (p.r.n. salbutamol) | up to 28 weeks |
| Median time to onset of therapeutic response after first dose | after 4 weeks |
| Number of patients with 15% response above baseline for each treatment at each timepoint after first dose | at week 4, 12, 20 |
| Number of patients with 15% response above baseline for each treatment at each timepoint after 4 weeks | at week 8, 16, 24 |
| Pre-dose morning and evening peak expiratory flow rate (PEFR) measured by patients | up to 28 weeks |
