What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total International prostate symptom score(IPSS) score before and after treatment

    Assess the improvement of lower urinary tract symptoms with change in total IPSS score before and after treatment.

    Measured: For 12 weeks

Secondary outcomes (5)
  1. Quality of life(QoL) score before and after treatment

    Assess the improvement of lower urinary tract symptoms with change in QoL score before and after treatment.

    Measured: For 12 weeks

  2. Maximal urinary flow rate(Qmax) before and after treatment

    Assess the improvement of lower urinary tract symptoms with change in Qmax before and after treatment.

    Measured: For 12 weeks

  3. Voiding score of IPSS before and after treatment

    Assess the improvement of lower urinary tract symptoms with change in voiding scores before and after treatment.

    Measured: For 12 weeks

  4. Storage scores of IPSS before and after treatment

    Assess the improvement of lower urinary tract symptoms with change in storage scores before and after treatment.

    Measured: For 12 weeks

  5. Post void residual urine volume(PVR) before and after treatment

    Assess the improvement of lower urinary tract symptoms with change in post void residual urine volume(PRV) before and after treatment.

    Measured: For 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Silodosin in people with Benign Prostatic Hyperplasia, run by JW Pharmaceutical at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Mar 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total International prostate symptom score(IPSS) score before and after treatment (time frame: For 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Mar 2012.
