Outcome Measures

Primary Outcomes (1)

  • The primary objective of the study is to evaluate the effects of silodosin on LUTS in terms of IPSS response rate (decrease from baseline ≥ 25% in the IPSS total score)

    6 months o treatment

Secondary Outcomes (1)

  • Change from baseline in IPSS total score

    4, 12, 24 weeks of treatment

Other Outcomes (1)

  • Percentage of subjects improving each symptom of the ICS (International Continence Society) male questionnaire as compared to baseline; to evaluate the effect of silodosin on the most frequent and bothersome symptoms

    6 months of treatment

Study Arms (1)

Silodosin

EXPERIMENTAL

Silodosin capsule 8 mg daily for 24 weeks

Drug: Silodosin

Interventions

8 mg daily for 24 weeks

Eligibility Criteria

Age60 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Clinical diagnosis of Benign Prostatic Hyperplasia (BPH) by the urologist;
  • Male subjects aged 60 years or older;
  • IPSS total score equal or more than 12 at Visit 1 (Screening) and 2 (Baseline);
  • Able to comply with protocol procedures;
  • Written informed consent obtained before beginning any investigational procedures.

You may not qualify if:

  • 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 serrulate/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 cytochrome P450 3A4 inhibitors, such as ketoconazole, itraconazole or ritonavir (possible pharmacokinetic interaction);
  • Prostate cancer;
  • History of prostate or bladder neck surgery, including transurethral prostatectomy, 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, percutaneous transluminal coronary angioplasty, 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;
  • +1 more criteria
