E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of the study is to confirm in a larger and less selected population (“real life conditions”) the positive risk-benefit balance observed with silodosin in double-blind, randomised clinical trials. |
|
E.2.2 | Secondary objectives of the trial |
The effectiveness and safety of the drug will be investigated also in different subgroups of subjects according to age, severity of the disease, concomitant disease and medications. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Clinical diagnosis of BPH by the urologist; - Male subjects aged 60 years or older; - IPSS total score ≥12 at Visit 1 (Screening) and 2 (Baseline); - Able to comply with protocol procedures; - Written informed consent obtained before beginning any investigational procedures. |
|
E.4 | Principal exclusion criteria |
- Hypersensitivity to the active substance or to any of the excipients; - Patients for whom cataract surgery is scheduled; - History of orthostatic hypotension or syncope; - Moderate or severe renal impairment (CLCR <50 ml/min, as estimated by the Cockcroft Gault formula); - Severe hepatic impairment; - Concomitant use of other α-adrenoreceptor antagonists or natural/herbal products known to have an effect on LUTS (e.g. saw palmetto - serenoa serulata/repens) . Patients already on treatment with those drugs may be enrolled after a 4 week wash-out period before Visit 2 (baseline); - Concomitant use with potent CYP3A4 inhibitors, such as ketoconazole, itraconazole or ritonavir (possible PK interaction); - Prostate cancer; - History of prostate or bladder neck surgery, including TURP, TUNA, laser or other minimally invasive therapy; - Active urinary tract infection; - Acute or recurrent prostatitis (more than 3 times in the last year); - History of neurological disease that may affect bladder function; - Unstable cardiovascular or cerebrovascular disease (including acute myocardial infarction, unstable angina pectoris, by-pass, PTCA, congestive heart failure class III-IV, stroke, transient ischemic attack and episodes of cardiac arrhythmia requiring treatment in the last 6 months); - History or current evidence of drug or alcohol abuse within the last 12 months; - Participation in a study involving the administration of an investigational compound within the past 30 days; - Any other condition which, in the investigator's judgement, renders the subject unable to complete the study or increases the risk to the subject or which prevents optimal participation in achieving the objectives of the study. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
The primary objective of the study is to evaluate the effect of silodocin on LUTS in terms of IPSS response rate (decrease from baseline >=25% in the IPSS total score) |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
The secondary objectives are: - effects on LUTS expressed as - effects on QoL due to urinary symptoms - safety profile - adherence to therapy - patient’s treatment satisfaction |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Baseline to week +24, follow-up information will be collected up to 4 weeks by a phone contact. |
