- Percent Predicted FEV1 AUC0-4 Response at the End of Week 12 [ Time Frame: Baseline, Week 12 ]Outcome measure description: Change from baseline in percent predicted Forced Expiratory Volume in one second (FEV1) Area Under the Curve from 0 to 4 hours (AUC0-4). Calculated as percent predicted at week 12 minus percent predicted at baseline.
- Percent Predicted FEV1 Trough Response at the End of Week 12 [ Time Frame: Baseline, Week 12 ]Outcome measure description: Change from baseline in percent predicted trough Forced Expiratory Volume in one second. Calculated as percent predicted at week 12 minus percent predicted at baseline.
- Percent Predicted FVC AUC0-4 Response at the End of Week 12 [ Time Frame: Baseline, Week 12 ]Change from baseline in percent predicted Forced Vital Capacity (FVC) Area Under the Curve from 0 to 4 hours (AUC0-4). Calculated as percent predicted at week 12 minus percent predicted at baseline.
- Percent Predicted FVC Trough Response at the End of Week 12 [ Time Frame: Baseline, Week 12 ]Change from baseline in percent predicted trough Forced Vital Capacity (FVC). Calculated as percent predicted at week 12 minus percent predicted at baseline.
- Pre-bronchodilator FEF25-75 Percent Predicted at the End of Week 12 [ Time Frame: Baseline, Week 12 ]Forced Expiratory Flow at 25-75% of vital capacity (FEF25-75). Calculated as percent predicted at week 12 minus percent predicted at baseline.
- Change From Baseline in Residual Volume/Total Lung Capacity (RV/TLC) at the End of Week 12 [ Time Frame: Baseline, Week 12 ]Change from baseline in static lung hyperinflation as measured by RV/TLC. Calculated as percent predicted at week 12 minus percent predicted at baseline.
- Respiratory and Systemic Symptoms Questionnaire (RSSQ) [ Time Frame: 12 weeks ]Outcome measure description: The RSSQ questionnaire is used to determine the presence or absence of an exacerbation during the recall period.
- Change From Baseline in CFQ Scores - Adult Group [ Time Frame: 12 weeks ]The Cystic Fibrosis questionnaire (CFQ) is a disease-specific instrument that measures health-related quality of life (HRQOL) for adults with CF. This validation questionnaire consists of 50 items on generic and disease-specific scales. The scores range from 0 to 100, with higher scores indicating better health.
- Change From Baseline in CFQ Scores - Adolescents Group [ Time Frame: 12 weeks ]The Cystic Fibrosis questionnaire (CFQ) is a disease-specific instrument that measures health-related quality of life (HRQOL) for adolescents (age 6-13) with CF. This validation questionnaire consists of 50 items on generic and disease-specific scales. The scores range from 0 to 100, with higher scores indicating better health.
- Change From Baseline in CFQ Scores - Parent Questionnaire [ Time Frame: 12 weeks ]The Cystic Fibrosis questionnaire (CFQ) is a disease-specific instrument that measures health-related quality of life (HRQOL) for adolescents with CF - parent questionnaire. This validation questionnaire consists of 50 items on generic and disease-specific scales. The scores range from 0 to 100, with higher scores indicating better health.
- Amount of Tiotropium Eliminated in Urine From 0 to 4 Hours at Steady State (Ae0-4,ss) [ Time Frame: pre-dose, and 5 minutes (min), 20 min, 1 hour (h), and 2 h post-dose ]Ae0-4,ss represents the amount of tiotropium that is eliminated in urine from time 0 to 4 hours at steady state
- Maximum Measured Concentration at Steady State (Cmax,ss) [ Time Frame: pre-dose, and 5 minutes (min), 20 min, 1 hour (h), and 2 h post-dose ]Cmax,ss represents the maximum measured concentration of tiotropium in plasma at steady state.
- Time From Dosing to the Maximum Concentration (Tmax,ss) [ Time Frame: pre-dose, and 5 minutes (min), 20 min, 1 hour (h), and 2 h post-dose ]Tmax,ss represents the time from dosing to the maximum concentration of tiotropium in plasma
- Clinical Relevant Abnormalities for Vital Signs and Laboratory Evaluation [ Time Frame: From first drug administration until 30 days after last drug administration (up to 121 days) ]Clinical Relevant Abnormalities for Vital Signs and Laboratory evaluation. Any new or clinically relevant worsening of baseline conditions was reported as Adverse Event.
