E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess whether the combination of solifenacin succinate 3, 6, 9 mg and tamsulosin OCAS 0.4 mg provides improved efficacy compared to tamsulosin OCAS 0.4 mg alone in males with LUTS associated with BPH. |
|
E.2.2 | Secondary objectives of the trial |
Safety and the tolerability of the combination of different doses of solifenacin succinate 0 placebo , 3, 6 and 9 mg and tamsulosin OCAS 0 placebo and 0.4 mg in males with LUTS associated with BPH. To assess the dose response relationship of the combination of different doses of solifenacin succinate 0 placebo , 3, 6 and 9 mg and tamsulosin OCAS 0 placebo and 0.4 mg in relieving voiding and storage symptoms in males with LUTS associated with BPH. To assess the efficacy of the combination of solifenacin succinate 3, 6, 9 mg and tamsulosin OCAS 0.4 mg compared with solifenacin succinate 3, 6, 9 mg alone in males with LUTS associated with BPH. To evaluate the pharmacokinetics of the combination of different doses of solifenacin succinate 0 placebo , 3, 6 and 9 mg and tamsulosin OCAS 0 placebo and 0.4 mg in males with LUTS associated with BPH. |

E.3 | Principal inclusion criteria |
At study entry 1. Male aged more than 45 years. 2. Written informed consent has been obtained. 3. Patient is willing and able to complete the micturition diary and questionnaires correctly. 4. Voiding symptoms including incomplete emptying of the bladder, intermittency, weak stream or hesitancy and storage symptoms including frequency, urgency or nocturia , diagnosed as LUTS associated with BPH formerly known as symptomatic BPH for more than 3 months. 5. A total I-PSS score of more than 13. 6. A maximum urinary flow rate of more than 4.0 mL/s and less than or equal to 15.0 mL/s, with a voided volume more than 120 mL during free flow minimum of 2 flows to be performed . At randomization 7. A total I-PSS score of more than 13. 8. Patient continues to meet all inclusion criteria of visit 1. |
|
E.4 | Principal exclusion criteria |
At study entry 1. Any significant post void residual volume PVR 200 mL at least 2 assessments to be performed . 2. Evidence of a symptomatic urinary tract infection or a known history or diagnosis of any of the following urinary conditions - Recurrent symptomatic urinary tract infection - Chronic inflammation such as interstitial cystitis - Stone in bladder or urethra - Previous pelvic radiation therapy - Previous or current malignant disease of the pelvic organs - Previous surgery to the bladder neck or prostate - Bladder neck stenosis - Urethral stricture 3. Narrow angle glaucoma, myasthenia gravis, severe gatro-intestinal condition including toxic megacolon or patients at risk for these conditions, urinary or gastric retention or any other medical condition which in the opinion of the investigator makes the use of anticholinergics contra-indicated. 4. Clinically significant cardiovascular or cerebrovascular diseases within 6 months prior to visit 1, such as myocardial infarction, uncontrolled angina, significant ventricular arrhythmias, heart failure NYHA class III/IV , a history of orthostatic hypotension or stroke. 5. Non-drug treatment for BPH or overactive bladder, including electrostimulation therapy at the start of the study or start of a bladder training program during the 2 weeks prior to or during the study. 6. Use of forbidden concomitant medication - Other pharmacological treatment for BPH, such as alfa-AR-antagonists and plant extracts within the 2 weeks prior to visit 1 . - 5alpha-reductase inhibitors within the 3 months prior to visit 1 . - Other drugs which may influence the pharmacodynamic effects of solifenacin or tamsulosin, combined alpha/beta-AR-antagonists, alpha-agonists, cholinergics or anti- cholinergics or CYP 3A4 inhibitors or inducers. This medication should be discontinued ultimately at visit 1 see Appendix 1 Part A . 7. Use of any drugs with cholinergic or anticholinergic side effects, diuretics, oral 2-agonists or PDE 5 inhibitors see Appendix 1 Part B . However, long term therapy 1 month prior to randomization on a stable dosage of these drugs is permissible. 8. Diabetic neuropathy. 9. A planned cataract surgery within 30 days after completion of the study. 10. Severe renal impairment including hemodialysis or moderate or severe hepatic impairment. 11. Known or suspected hypersensitivity to solifenacin, other anticholinergics, tamsulosin, other alpha-AR-antagonists, lactose or any of the other inactive ingredients of the study medication. 12. Any clinically significant condition, which in the opinion of the investigator makes the patient unsuitable for the trial. 13. Participation in any clinical trial within 30 days or the limit set by national law, whichever is longer prior to randomization. 14. Employees of the Astellas Group, the CROs involved, or the investigator site executing the study. At randomization 15. Patient did not complete the micturition diary or I-PSS questionnaire according to the instructions. 16. Total daily urine volume 3000 mL as verified in the micturition diary. 17. Any clinically significant abnormal ECG, which in the opinion of the investigator makes the patient unsuitable for the trial. 18. ALAT, ASAT or creatinine outside 2 times the normal range, gamma GT outside 3 times the normal range. 19. Any other clinically significant out of the normal range result of urinalysis, biochemistry including PSA or hematology, which in the opinion of the investigator makes the patient unsuitable for the trial. 20. Patient fulfils any exclusion criteria of visit 1. |
