Trial Outcomes & Findings for Effect of Testosterone in Men With Erectile Dysfunction (NCT NCT00512707)
NCT ID: NCT00512707
Last Updated: 2017-06-29
Results Overview
IIEF is a validated, 15-item questionnaire that assesses 5 domains of sexual function: erectile function (range 1-30), orgasmic function (range 0-10), sexual desire (range 2-10), intercourse satisfaction (range 0-15), and overall sexual satisfaction (range 2-10). Each question was answered on a 6-point or 5-point scale from 0/1 to 5 (best) with Erectile Function domain range of 1 to 30 with higher scores representing better function.

Testosterone
Active Testosterone Gel
Sildenafil citrate (open label): On demand use of sildenafil citrate (3 tablets per week). Starting dose of 50 mg. Titrated to 100 mg or 25 mg depending on efficacy and tolerability. Begins as open label run in period for 3 - 6 weeks, and continues during the placebo-controlled testosterone gel intervention for 16 weeks.
Testosterone gel 1% (active or placebo): Testosterone Gel 1%: Starting active dose 10 g/day. Increased to 15 g/day or decreased to 5 g/day in order to attain morning total testosterone level between 500 - 1000 ng/dL. Blinding achieved by combining a total of 3 tubes of active or placebo gel, applied to upper arms and shoulders each day.
Topical testosterone gel 1%: Testosterone Gel: Starting dose 10 g/day. Increased to 15 g/day or decreased to 5 g/day in order to attain morning total testosterone level between 500 - 1000 ng/dL. Blinded achieved by combining a total of 3 tubes of active or placebo gel.

PRIMARY outcome
Timeframe: Week 0, week 8, week 11, week 14Population: All available data expressed as absolute value at the given time-point.
IIEF is a validated, 15-item questionnaire that assesses 5 domains of sexual function: erectile function (range 1-30), orgasmic function (range 0-10), sexual desire (range 2-10), intercourse satisfaction (range 0-15), and overall sexual satisfaction (range 2-10). Each question was answered on a 6-point or 5-point scale from 0/1 to 5 (best) with Erectile Function domain range of 1 to 30 with higher scores representing better function.

Active Testosterone Gel
Sildenafil citrate (open label): On demand use of sildenafil citrate (3 tablets per week). Starting dose of 50 mg. Titrated to 100 mg or 25 mg depending on efficacy and tolerability. Begins as open label run in period for 3 - 6 weeks, and continues during the placebo-controlled testosterone gel intervention for 16 weeks.
Testosterone gel 1% (active or placebo): Testosterone Gel 1%: Starting active dose 10 g/day. Increased to 15 g/day or decreased to 5 g/day in order to attain morning total testosterone level between 500 - 1000 ng/dL. Blinding achieved by combining a total of 3 tubes of active or placebo gel, applied to upper arms and shoulders each day.
Topical testosterone gel 1%: Testosterone Gel: Starting dose 10 g/day. Increased to 15 g/day or decreased to 5 g/day in order to attain morning total testosterone level between 500 - 1000 ng/dL. Blinded achieved by combining a total of 3 tubes of active or placebo gel.

SECONDARY outcome
Timeframe: Week 0, Week 8, Week 14Population: All available data expressed as absolute value at the given time-point.
Well-being and mood were assessed using the Psychological General Well-Being Index (PGWBI), a 22-item questionnaire that evaluated six dimensions of self-reported wellness: Anxiety (5 questions), Depressed Mood (3 questions), Positive Well-Being (4 questions), Self Control (3 questions), General Health (3 questions), and Vitality (4 questions). Higher scores in each dimension reflect increasing well-being. A global score (ranging from 0 (poor QoL) to 110 (good QoL)) was calculated as the sum of each domain score. The global score and those of its 6 dimensions were normalized to a 100% scale to facilitate comparison.

SECONDARY outcome
Timeframe: Week 0, Week 8, Week 14Population: All available data expressed as absolute value at the given time-point.
The Derogatis Affects Balance Scale (DABS) is a 40-item mood inventory and consists of 4 positive affect dimensions (joy, contentment, vigor, and affection) as well as 4 negative affect dimensions(anxiety, depression, guilt, and hostility). Each domain was calculated as the sum of 5-items and could range from 0 to 20, wherein higher scores indicate greater affectivity.

SECONDARY outcome
Timeframe: Week 0, Week 8, Week 14Population: All available data expressed as absolute value at the given time-point.
The Derogatis Affects Balance Scale (DABS) is a 40-item mood inventory and consists of 4 positive affect dimensions (joy, contentment, vigor, and affection) as well as 4 negative affect dimensions(anxiety, depression, guilt, and hostility). Positive Affects Ratio (PAR), ranging from 0 to 1, is the proportion of total scores (sum of all 8 domains) that is positive (sum of 4 positive domains). Higher PAR represents better affectivity.
