-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Adverse Events (AEs) | Safety is monitored by collecting AEs, which include abnormal lab parameters, vital signs or ECG data if the abnormality induced clinical signs or symptoms, needed active intervention, interruption or discontinuation of study drug or was clinically significant. A serious AE (SAE) was an AE resulting in death, persistent or significant disability/incapacity or congenital anomaly/birth defect, was life-threatening, required or prolonged hospitalization or was considered medically important. AEs were assessed by the Investigator for intensity (mild-no disruption of normal daily activities, moderate-affected normal daily activities or severe-inability to perform daily activities) and for causal relationship to study drug. A treatment-emergent adverse event (TEAE) was defined as an AE that occurred after the intake of first dose of double-blind study drug (if on FDC in 905-CL-055) or after first open-label dose until 30 days after the last dose of open-label study drug (in 905-CL-057). | From first dose of double-blind study drug (if on FDC in 905-CL-055) or first open-label dose up to 30 days after last dose of open-label study drug (in 905-CL-057) (up to 56 weeks) | 
| Change From Baseline to End of Treatment in Post Void Residual (PVR) Volume | PVR volume is the volume of urine retained after voiding. PVR volume was assessed by ultrasonography or bladder scan. | Baseline and up to 52 weeks of FDC treatment | 
| Change From Baseline to End of Treatment in Maximum Flow Rate (Qmax) | Qmax during a micturition (urination) was recorded using uroflowmetry. | Baseline and up to 52 weeks of FDC treatment | 
| Change From Baseline to End of Treatment in Average Flow Rate (Qmean) | Qmean during a micturition (urination) was recorded using uroflowmetry. | Baseline and up to 52 weeks of FDC treatment | 
| Change From Baseline to End of Treatment in Total International Prostate Symptom Score (IPSS) | The International Prostate Symptom Score (IPSS) is a validated global questionnaire to assess the degree of urinary symptoms, based on answers to 7 questions concerning urinary symptoms: Incomplete emptying of the bladder Intermittency Weak stream Hesitancy Frequency Urgency Nocturia Each question is assigned points from 0 to 5 indicating increasing severity of the symptom. Total score can range from 0 to 35 (mildly symptomatic to severely symptomatic). | Baseline and up to 52 weeks of FDC treatment | 
| Change From Baseline to End of Treatment in Total Urgency Frequency Score (TUFS) (Previously Known as Total Urgency Score [TUS]) | The Patient Perception of the Intensity of Urgency Scale (PPIUS) is a validated scale completed as part of the micturition diary. For each micturition and/or incontinence episode, the participant rated the degree of associated urgency according to the following 5-point categorical scale: 0. No urgency; 1. Mild urgency; 2. Moderate urgency; 3. Severe urgency; 4. Urgency incontinence TUS/TUFS was calculated as the sum of the PPIUS gradings from the 3-day diary divided by the number of days on which urgency grading was recorded. Higher scores indicate more severe urgency. | Baseline and up to 52 weeks of FDC treatment |
