March 17, 2016 updated by: Astellas Pharma Taiwan, Inc.
An Open-label, Randomized, Parallel Study to Evaluate the Clinical Efficacy and Safety of Tamsulosin Alone or in Combination With Solifenacin for the Treatment in Men With Lower Urinary Tract Symptoms Including Overactive Bladder Symptoms
The objective of this study is to evaluate the clinical efficacy and safety of tamsulosin alone or in combination with solifenacin for the treatment in men with lower urinary tract symptoms (LUTS) including overactive bladder (OAB) symptoms in Taiwan.

Description
Inclusion Criteria:
- Clinical signs and symptoms of frequency and urgency related to benign prostatic hyperplasia for at least 3 months
- I-PSS(S) score of ≥ 12
- Maximum flow rate (Qmax) of 4 to15 mL/sec
- Mean urinary frequency of ≥ 8 micturitions per 24 hours and ≥ 1 episode of urgency per 24 hours as verified by the 3-day micturition diary
- Benign digital rectal examination (DRE) result
Exclusion Criteria:
- Clinically significant outflow obstruction
- Significant post void residue volume (PVR >100ml)
- Prostate specific antigen (PSA) ≥10 ng/mL
- Previous or planned prostate surgery, including transurethral resection of the prostate (TURP)
- Transurethral microwave treatment (TUMT), transurethral needle ablation (TUNA), laser, or other invasive or minimally invasive procedures within 12 months
- Patient with a neurological cause for abnormal detrusor activity
- Patients with urinary tract infection, chronic inflammation, bladder stones, bladder neck, sclerosis, urethral stricture, prostatic cancer, severe vesical diverticulum
- Uncontrolled narrow angle glaucoma, urinary or gastric retention or any other medical condition which in the opinion of the investigator makes the use of anticholinergics contra-indicated
- Patients with any other complication which may cause voiding dysfunction
- Patients with severe hepatic dysfunction, severe renal dysfunction, severe cardiovascular disorder, orthostatic hypotension, or senile dementia
- Patients receiving any medication therapy for LUTS/BPH 2 weeks prior to the study
- Use of drugs to treat incontinence currently
- Hypersensitivity to tamsulosin and/or solifenacin or to any component of the formulation
- Any clinically significant condition, which in the opinion of the investigator makes the patients unsuitable for the trial
- Patients had taken any investigational drug in the previous 3 months prior to this study
