Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Change From Baseline in Forced Vital Capacity (FVC)
Time Frame: Baseline, Week 6
|
Spirometry was conducted according to American Thoracic Society standards.
A spirometer was used to measure FVC, the maximum amount of air exhaled from the lungs after taking the deepest breath possible, at Baseline and Week 6.
A positive change from Baseline indicated improvement.
|
Baseline, Week 6
|
|
Change From Baseline in Forced Expiratory Volume in One Second (FEV1)
Time Frame: Baseline, Week 6
|
Spirometry was conducted according to American Thoracic Society standards.
A spirometer was used to measure FEV1, the maximum amount of air exhaled in one second, at Baseline and Week 6.
The highest value at each time-point was recorded.
A positive change from Baseline indicated improvement.
|
Baseline, Week 6
|
|
Change From Baseline in FEV1/FVC Ratio
Time Frame: Baseline, Week 6
|
The FEV1/FVC ratio was calculated by dividing the FEV1 value by the FVC value representing the portion (or ratio) of FVC exhaled in one second.
A positive change from Baseline indicated improvement.
|
Baseline, Week 6
|

Measure Description |
Time Frame |
|---|---|---|
|
Change From Baseline in the Number of Urinary Incontinence Episodes
Time Frame: Baseline, Week 6
|
The number of urinary incontinence episodes or leakage occurring over the previous 3 days was recorded in the patient bladder diary at Baseline and prior to Week 6.
A negative change from Baseline indicated improvement (less incontinence/leakage).
|
Baseline, Week 6
|
|
Change From Baseline in the Maximum (Amplitude) Detrusor Pressure (MDP)
Time Frame: Baseline, Week 6
|
MDP was measured at the first involuntary detrusor contraction using urodynamic testing.
A catheter was inserted into the bladder at Baseline and Week 6 and the pressure [measured in centimeters water (cm H20)] was determined as the bladder filled.
A negative change from Baseline indicated improvement (less Detrusor pressure).
|
Baseline, Week 6
|
|
Change From Baseline in Maximum Cystometric Capacity (MCC)
Time Frame: Baseline, Week 6
|
MCC (the maximum amount of urine the bladder could hold) was measured using urodynamic testing.
The amount of urine collected was subtracted from the total volume infused measured as milliliters (mL) of urine.
A positive change from Baseline indicated improvement (fuller bladder/ less incontinence).
|
Baseline, Week 6
|

Measure Description |
Time Frame |
|---|---|---|
|
Number of Participants With at Least a 15% Decrease From Baseline in FVC
Time Frame: Baseline, Weeks 2, 6 and 12
|
Spirometry was conducted according to American Thoracic Society standards.
A spirometer was used to measure FVC, the maximum amount of air exhaled from the lungs after taking the deepest breath possible at Baseline, Weeks 2, 6 and 12.
|
Baseline, Weeks 2, 6 and 12
|
|
Number of Participants With at Least a 20% Decrease From Baseline in FVC
Time Frame: Baseline, Weeks 2, 6 and 12
|
Spirometry was conducted according to American Thoracic Society standards.
A spirometer was used to measure FVC, the maximum amount of air exhaled from the lungs after taking the deepest breath possible at Baseline, Weeks 2, 6 and 12.
