What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline to 12 Week Endpoint in International Index of Erectile Function (IIEF) Erectile Function (EF) Domain Score
The IIEF EF domain score was the sum of Questions (Q) 1 to Q5 and Q15 of the IIEF self-reported questionnaire. Q1 to Q5 were rated 0 (low/no EF) to 5 (high EF) and Q15 was rated 1 (no/low confidence) to 5 (high confidence). IIEF EF domain scores ranged from 1 to 30. Higher scores denoted better EF.
Measured: Baseline, Week 12
Secondary outcomes (9)
Change From Baseline to 12 Week Endpoint in the Percentage of "Yes" Responses on the Sexual Encounter Profile (SEP) Diary
The SEP diary was a participant-assessed diary with 5 questions (Q): Q1 (erection achievement), Q2 (successful penetration), Q3 (successful intercourse), Q4 (satisfied with erection), and Q5 (satisfied with sexual experience) for each sexual encounter made over a specified period of time. SEP Q1 to Q5 scores were determined as a percentage of "Yes" responses to each of the 5 questions out of all sexual attempts recorded during the time period. A higher percentage of "Yes" responses indicated better EF. Assessed was the mean change from baseline in the percentage of "Yes" responses to the SEP diary Q1 to Q5. The least squares (LS) mean was estimated from a repeated measures analysis of covariance model that included terms for treatment, visit, treatment*visit, baseline, baseline*treatment (if p-value <0.25).
Measured: Baseline, Week 12
Change From Baseline to 12 Week Endpoint in IIEF Domain Scores (Intercourse Satisfaction, Orgasmic Function, Sexual Desire, and Overall Satisfaction)
Intercourse Satisfaction (IS) domain score: sum of Questions (Q) 6, Q7, and Q8, each rated 0 (low/no satisfaction) to 5 (high satisfaction). IS domain score range: 0 to 15; lower scores denoted lower satisfaction. Orgasmic Function (OF) domain score: sum of Q9 and Q10, each rated 0 (no sexual stimulation) to 5 (almost always/always). OF domain score range: 0 to 10; lower scores denoted lower OF. Sexual Desire (SD) domain score: sum of Q11 and Q12, each rated 1 (almost never or low/no sexual desire) to 5 (almost always or very high sexual desire). SD domain score range: 2 to 10; lower scores denoted lower SD. Overall Satisfaction (OS) domain score: sum of Q13 and Q14, each rated 1 (low/no satisfaction) to 5 (high satisfaction). OS domain score range: 2 to 10; lower scores denoted lower OS. Least squares (LS) mean estimated from repeated measures analysis of variance model that included terms for treatment, visit, treatment*visit, baseline, baseline*treatment (if p-value<0.25).
Measured: Baseline, Week 12
Change From Baseline to 12 Week Endpoint in the Percentage of Participants Who Return to "Normal" on the International Index of Erectile Function (IIEF) Scale (EF>25)
The percentage of participants whose IIEF Erectile Function (EF) domain scores changed from ≤25 at baseline to >25 (normal) at Week 12. The IIEF EF domain score was the sum of IIEF Question (Q) 1 to Q5 and Q15. Q1 to Q5 were rated 0 (low/no EF) to 5 (high EF) and Q15 was rated 1 (no/low confidence) to 5 (high confidence). IIEF EF domain scores ranged from 1 to 30. Higher scores denoted better EF.
Measured: Baseline, Week 12
Change From Baseline to 12 Week Endpoint in IIEF EF Domain Score Reported by Testosterone Concentration Subgroups
The International Index of Erectile Function (IIEF) EF was the sum of Questions (Q) 1 to Q5 and Q15 of the IIEF Self-reported questionnaire. Q1 to Q5 were rated 0 (low/no erectile function) to 5 (high erectile function) and Q15 was rated 1 (no/low confidence) to 5 (high confidence). IIEF EF domain scores ranged from 1 to 30. Higher scores denoted better EF. Testosterone concentration subgroups were based on optimal baseline testosterone levels (<340 nanograms per deciliter [ng/dL] or ≥340 ng/dL). The least squares (LS) mean was estimated from an analysis of covariance (ANCOVA) model that included terms for treatment group, baseline, and baseline*treatment interaction (if p-value<0.25).
Measured: Baseline, Week 12
Change From Baseline to 12 Week Endpoint in Prostate-Specific Antigen (PSA)
The least squares (LS) mean was estimated from a repeated measures analysis of covariance model that included terms for treatment, visit, treatment*visit, baseline, baseline*treatment (if p-value<0.25).
Measured: Baseline, Week 12
Change From Baseline to 12 Week Endpoint in Total Cholesterol and Triglycerides
The least squares (LS) mean was estimated from a repeated measures analysis of covariance model that included terms for treatment, visit, treatment*visit, baseline, baseline*treatment (if p-value<0.25).
Measured: Baseline, Week 12
Percent Change From Baseline to 12 Week Endpoint in High-Density Lipoprotein Cholesterol (HDL-C) and Low-Density Lipoprotein Cholesterol (LDL-C)
The least squares (LS) was estimated from a repeated measures analysis of covariance model that included terms for treatment, visit, treatment*visit, baseline, baseline*treatment (if p-value<0.25).
Measured: Baseline, Week 12
Change From Baseline to 12 Week Endpoint in Fasting Glucose
The least squares (LS) mean was estimated from a repeated measures analysis of covariance model that included terms for treatment, visit, treatment*visit, baseline, baseline*treatment (if p-value<0.25).
Measured: Baseline, Week 12
Change From Baseline to 12 Week Endpoint in Fasting Insulin
Change from baseline to 12 Week endpoint in fasting blood insulin concentration. The least squares (LS) mean was estimated from a repeated measures analysis of covariance model that included terms for treatment, visit, treatment*visit, baseline, baseline*treatment (if p-value<0.25).
Measured: Baseline, Week 12

Primary outcome
Change From Baseline to 12 Week Endpoint in International Index of Erectile Function (IIEF) Erectile Function (EF) Domain Score
Time frame: Baseline, Week 12
The IIEF EF domain score was the sum of Questions (Q) 1 to Q5 and Q15 of the IIEF self-reported questionnaire. Q1 to Q5 were rated 0 (low/no EF) to 5 (high EF) and Q15 was rated 1 (no/low confidence) to 5 (high confidence). IIEF EF domain scores ranged from 1 to 30. Higher scores denoted better EF.

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 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.

What does the primary outcome measure?
Change From Baseline to 12 Week Endpoint in International Index of Erectile Function (IIEF) Erectile Function (EF) Domain Score (time frame: Baseline, Week 12). 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 9 Apr 2019.
