Brief Summary:
Study FDC114615 is a two year, multi-centre, randomised, open-label trial to assess the efficacy of Dutasteride plus tamsulosin when compared to the standard practice of watchful waiting, with a defined escalation to tamsulosin in treatment naive men with symptomatic benign prostate hyperplasia (BPH).
Once consented, each subject will undergo screening procedures to ensure the prostate volume and post void residual are within eligible range. If all entry criteria are met, subjects will be randomised (1:1) to receive Dutasteride plus tamsulosin with lifestyle advice or watchful waiting, with lifestyle advice, with a defined escalation to tamsulosin. Escalation will be initiated when no improvement from baseline is scored using the International Prostate Symptom Score (version 2) (IPSS) questionnaire.
After randomisation, the subjects return to site at one month, then every 13 weeks until two years of treatment is complete or they are withdrawn. Key assessments, such as Adverse Events (AE's) and concomitant medication monitoring and completion of the quality of life questionnaires are performed at each visit and the data recorded.

Detailed Description:
This will be a European, multicentre, randomised, open-label, parallel group study. The aim of the study is to investigate whether Dutasteride plus Tamulson treatment with lifestyle advice is more effective than watchful waiting treatment plus lifestyle advice plus step-up therapy with tamsulosin for improvement of symptoms and Acte Urinary Retention (AUR) and BPH-related prostatic surgery, in older men (≥50 yrs), with moderate symptoms of BPH (IPSS 8-19), enlarged prostates (≥30cc) and Prostate Specific Antigen (PSA) ≥1.5ng/mL.
Data from all participating centres will be pooled prior to analysis. Investigative centres will be pooled a priori into clusters based on geographic location; these clusters may be used in analyses to adjust for site effects. Clusters will be defined once all investigative centres have been identified and randomisation has been completed.
Subjects will be screened for inclusion into the study and eligible subjects will be randomised by investigative centre. Subjects will be allocated to one of two treatment groups, according to a pre-determined randomisation schedule (in a 1:1 ratio):
* Dutasteride plus tamsulosin once daily plus lifestyle advice.
* Watchful waiting plus lifestyle advice. Escalation to tamsulosin 0.4 mg once daily at any visit from Week 4 if any IPSS measurement shows no improvement or worsening from baseline. At any study visit, if the IPSS is the same or greater than the baseline value for that subject, tamsulosin 0.4 mg once daily will be initiated. If tamsulosin is initiated, it will be continued for the remainder of the study unless the subject elects to withdraw from the study. Initiation of tamsulosin will be recorded in the electronic case report form (eCRF.) Subjects will self-administer study medication once daily for up to 104 weeks, (up to 100 weeks for those on tamsulosin). Subjects will return to the clinic at 4 weeks post-randomisation and then at 13-week intervals post-randomisation during the 2-year treatment period (i.e. at 4, 13, 26, 39, 52, 65, 78, 91 and 104 weeks) for the assessments listed as in Appendix 1 Time and Events Schedule.
Approximately 760, treatment naive men with symptomatic BPH will be randomised into the study in order to achieve at least 592 evaluable subjects. 380 into the Dutasteride plus tamsulosin with lifestyle advice arm and 380 into the watchful waiting plus lifestyle advice arm.
Treatment naïve is defined as a man that has recently been diagnoses with BPH whom has received no prescribed therapeutic treatment. For example, medicines such as 5 α-reductase inhibitors (5-ARIs) or invasive procedures such as transurethral resection of the prostate (TURP) prescribed to directly treat the BPH symptoms are considered therapeutic treatments. As per the entry criteria, phytotherapy is allowed unless it was performed less than two weeks prior to the screening visit.
The anticipated recruitment period will be approximately 6 months. The study will be conducted in approximately 8 countries within Europe.
