Study of Solifenacin Succinate and Tamsulosin Hydrochloride OCAS in Males With Lower Urinary Tract Symptoms

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).

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 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.

A micturition is any voluntary urination, excluding episodes of incontinence only.The mean number of micturitions per 24 hours was calculated from data recorded by the participant in the micturition diary for the 3 days preceding each clinic visit.

A micturition is any voluntary urination, excluding episodes of incontinence only. The mean volume voided per micturition was calculated from data recorded by the participant in the micturition diary for the 3 days preceding each clinic visit.

A micturition is any voluntary urination, excluding episodes of incontinence only. The maximum volume voided per micturition was calculated from data recorded by the participant in the micturition diary for the 3 days preceding each clinic visit.

An urgency episode is defined as an episode of strong desire to void accompanied by fear of leakage or pain. The mean number of urgency episodes with PPIUS grade 3 (Severe urgency) or 4 (Urgency incontinence) per 24 hours was calculated from data recorded by the participant in the micturition diary for the 3 days preceding each clinic visit.

An urgency incontinence episode is defined as an episode with any involuntary leakage of urine accompanied by or immediately preceded by urgency. The mean number of urgency incontinence episodes with PPIUS grade 3 (Severe incontinence) or 4 (Urgency incontinence) per 24 hours was calculated from data recorded by the participant in the micturition diary for the 3 days preceding each clinic visit.

An incontinence episode is defined as an episode with any involuntary loss of urine. The mean number of incontinence episodes per 24 hours was calculated from data recorded by the participant in the micturition diary for the 3 days preceding each clinic visit.

A nocturia episode is defined as waking up at night to void (i.e., any voiding associated with sleep disturbance between the time the participant goes to bed with the intention to sleep until the time the patient gets up in the morning with the intention to stay awake). The mean number of nocturia episodes per 24 hours was calculated from data recorded by the participant in the micturition diary for the 3 days preceding each clinic visit.

The mean number of pads per 24 hours was calculated from data recorded by the participant in the micturition diary for the 3 days preceding each clinic visit.

The IPSS is a validated global questionnaire to assess the degree of urinary symptoms based on answers to 7 questions. Each question is assigned points from 0 to 5 indicating increasing severity of the particular symptom. The voiding score is the sum of the responses to 4 voiding questions (incomplete emptying of the bladder, intermittency, weak stream, hesitancy) and ranges from 0 to 20 (mildly symptomatic to severely symptomatic).

The IPSS is a validated global questionnaire to assess the degree of urinary symptoms based on answers to 7 questions concerning urinary symptoms. Each question is assigned points from 0 to 5 indicating increasing severity of the particular symptom. The storage symptom score is the sum of the responses to 3 storage questions (frequency, urgency and nocturia) and ranges from 0 to 15 (mildly symptomatic to severely symptomatic).

The QoL assessment was a single question asking the participant how he would feel about tolerating his current level of symptoms for the rest of his life. The answers ranged from 0 to 6 (delighted to terrible).

The Overactive Bladder Questionnaire (OAB-q) is a self-reported questionnaire with items relating to Symptom Bother and health-related quality of life (HRQoL). The Symptom Bother portion consists of an 8-item scale scored from 1 to 6. The total symptom bother score was calculated from the 8 answers and then transformed to range from 0 to 100, with 100 indicating worst severity. A negative change from baseline indicates an improvement.

The Overactive Bladder Questionnaire (OAB-q) is a self-reported questionnaire with items relating to Symptom Bother and health-related quality of life (HRQoL). The HRQoL portion consists of an 25-item HRQoL subscale containing the following domains scored from 1 to 6: - coping - concern - sleep - social interaction Coping score can range from 8 to 48 (none of the time to all of the time) and transformed to a scale from 0 to 100, with higher scores indicating better quality of life. A positive change from baseline indicates an improvement.

The HRQoL portion consists of an 25-item HRQoL subscale containing the following domains scored from 1 to 6: •coping •concern •sleep •social interaction Total score is calculated by adding the 4 HRQoL subscale scores and transforming to a scale from 0 to 100, with higher scores indicating better quality of life. A positive change from baseline indicates an improvement.

A OAB-q responder was defined as a participant with an improvement from baseline in HRQoL subscale total score ≥ 10.

The European quality of life-5 dimensions (EQ-5D) is an international standardized non-disease specific instrument for describing and valuing health status. The EQ5D has 5 domains: - mobility - self-care - usual activity - pain/discomfort - anxiety/depression Each domain has 3 response levels (1= no problem, 2= some problems, 3 = confined to bed).

Safety is monitored by collecting AEs, which include abnormal laboratory parameters, vital signs or ECG data if the abnormality induced clinical signs or symptoms, needed active intervention, interruption or discontinuation of study medication or was clinically significant. A serious AE (SAE) was an event resulting in death, persistent or significant disability/incapacity or congenital anomaly or birth defect, was life-threatening, required or prolonged hospitalization or was considered medically important. AEs were assessed by the Investigator for intensity as 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 administration of the first dose of double-blind study drug until 14 days after the last dose of double-blind study drug.

PVR volume is the volume of urine retained after voiding. PVR volume was assessed by ultrasonography or bladder scan.
