About this study

Official title: Randomized, Double Blind, Multicenter, Placebo Controlled, Proof of Concept Trial to Assess the Efficacy and Safety of 4 Weeks Treatment With AUS 131 (S Equol) on Benign Prostatic Hyperplasia

The purpose of this study is to assess the safety and effectiveness of S-equol in men with benign prostatic hyperplasia.

Read the detailed description

The study is a phase 2a, randomized, double blind, multicenter, placebo controlled, parallel group, proof of concept study comparing the efficacy, safety, and acceptability of S-equol to placebo in patients with benign prostatic hyperplasia. The study objective is to examine a dose response of 3 dose levels of S equol versus placebo on prostate specific antigen concentrations in patients with benign prostatic hyperplasia. The safety of S-equol will be evaluated during the study.

Conditions: Benign Prostatic Hyperplasia
Being tested: S-equol, Placebo
Medical subject headings: Prostatic Hyperplasia

What is being measured

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

Change From Baseline at Week 4 in Prostate Specific Antigen (PSA) Concentration.
Prostate specific antigen is considered to be the most sensitive measure of S-equol effects on the prostate, due to the expected effects of S-equol on the androgen receptor axis. In this proof-of-concept study, a population of 124 male subjects was estimated to achieve approximately 104 completed subjects (based on an estimated drop-out rate of 15%) to examine the dose-response compared to placebo. A sample size of 26 subjects in each treatment arm was considered to be adequate to observe a trend in this proof-of-concept study.
Measured: 4 weeks

Secondary outcomes (13)

Participants Assessment of Nocturia at Week 4
Participants were asked to rate their change in nocturia (number of times you wake from sleep to urinate) since the Baseline Visit.
Measured: 4 weeks
Investigators Assessment of Nocturia at Week 4
Investigators were asked to rate participant's change in nocturia since the Baseline Visit.
Measured: 4 weeks
Change in I-PSS Total Score From Baseline at Week 4
The International Prostate Symptom Score (I-PSS) is based on the answers to seven questions concerning urinary symptoms and one question concerning quality of life. Each question concerning urinary symptoms allows the patient to choose one out of 6 answers indicating increasing severity of the particular symptom. The answers are assigned points from 0 to 5. The total score can therefore range from 0 to 35 (asymptomatic to very symptomatic). The first seven questions of the I-PSS are identical to the questions appearing on the American Urological Association (AUA) Symptom Index which currently categorizes symptoms as follows: Mild (symptom score less than of equal to 7); Moderate (symptom score range 8-19); and Severe (symptom score range 20-35). A reduction in I-PSS Total Score is consistent with improvement in symptoms of BPH.
Measured: 4 weeks
Change in DAN Prostate Symptom Scale From Baseline at Week 4
The questionnaire is made up of two kinds of questions: intensity of a symptom and bothersomeness of a symptom. Prostate symptoms are addressed in questions 1 - 12 and sexual function in questions 13 - 15. Patients indicate how intense/frequent (scoring 0, 1, 2, or 3; where 0 represents the best case and 3 the worst case) and how bothersome the symptom (scoring 0, 1, 2, or 3; where 0 is 'not at all' and 3 is 'very much'). DAN-PSS total and DAN-PSS total sexual function score were calculated by multiplying the frequency score by the trouble score of each symptom, and then adding the resulting figures. The possible values of DAN-PSS total ranged from 0 to 108 and of DAN-PSS total sexual function score ranged from 0 to 27. A reduction in DAN-PSS total and/or sexual function score is consistent with improved BPH symptoms/sexual functioning.
Measured: 4 weeks

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 May 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

What does the primary outcome measure?

Change From Baseline at Week 4 in Prostate Specific Antigen (PSA) Concentration. (time frame: 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00962390.

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 19 May 2017; AzTrials last refreshed its copy on 7 Nov 2026.
