Brief Summary:
A new drug for benign prostatic hyperplasia is used for 9 months to determine its long-term safety.

Condition or disease Intervention/treatment Phase
Benign Prostatic Hyperplasia Drug: Silodosin Phase 3

Detailed Description:

This will be a multi-center, open-label 40 week investigation in up to 1,200 men with signs and symptoms of benign prostatic hyperplasia. The following procedures are utilized: physical exams, electrocardiograms, clinical laboratory tests, vital signs, the International Prostate Symptom Score, maximum urine flow rate, adverse events, concomitant medications, and compliance.

All subjects had previously participated in a 12-week double-blind placebo controlled trial (NCT000224107 or NCT000224120)

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Adverse Events [ Time Frame: 9 months ]
    All reported adverse events were recorded. Clinically significant abnormal laboratory values or other clinical findings upon examination were also recorded as adverse events.


Secondary Outcome Measures :
  1. International Prostate Symptom Score (IPSS) [ Time Frame: 9 months ]
    The IPSS is a symptom severity scale from 0 to 35 that is derived from a 7 item questionnaire. 0 indicates no symptoms and 35 indicates most severe symptoms.
