Zeitfenster
Change From Baseline to 12 Week Endpoint in Nocturnal Penile Tumescence (NPT) Pattern: Number of Erectile Events Per Night
Zeitfenster: Baseline, Week 12
NPT was measured using electrobioimpedance volumetric assessment (NEVA). The NEVA device measures a man's erections during the night. The man wears the device for three nights prior to visit 2 (baseline), visit 5 (end of randomised treatment) and visit 6 (end of follow-up). Data are entered for the 2 nights prior to the visit. During the night the man may have multiple erections. The number of erections is recorded.
Baseline, Week 12
Change From Baseline to 12 Week Endpoint in Nocturnal Penile Tumescence (NPT) Pattern: Duration of Erectile Events Per Night
Zeitfenster: Baseline, Week 12
NPT was measured using electrobioimpedance volumetric assessment (NEVA). The NEVA device measures a man's erections during the night. The duration of erections are measured and recorded. Data presented are the duration of erectile events at baseline and the change from baseline to Week 12.
Baseline, Week 12
Change From Baseline to 12 Week Endpoint in Nocturnal Penile Tumescence (NPT) Pattern: Percentage Volumetric Change
Zeitfenster: Baseline, Week 12
NPT was measured using electrobioimpedance volumetric assessment (NEVA). The NEVA device measures a man's erections during the night. The percent of volume change of the penis during erections is measured and recorded for each erection. Data presented are mean percentage of volumetric change from baseline to Week 12.
Baseline, Week 12
Change From Baseline to 12 Week Endpoint in the Frequency of Spontaneous Morning Erections Captured by Patient Diary
Zeitfenster: Baseline, 12 weeks
The morning erection diary allows the participant to record whether he experienced an erection on waking. The participant is to complete the morning erection diary every morning during the run-in, treatment and follow-up periods. The percentage of mornings the participant reported an erection is analysed.
Baseline, 12 weeks
The Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) Questionnaire at 12 Week Endpoint
Zeitfenster: Week 12
The subject questionnaire consists of 11 questions. Each question is rated on a scale of 0 (extremely low treatment satisfaction) to 4 (extremely high treatment satisfaction). The EDITS summary score will be obtained by adding each individual result for all questions, dividing by the number of questions answered (mean satisfaction score), and multiplying by 25, thus obtaining a score that ranges from 0 (extremely low treatment satisfaction) to 100 (extremely high satisfaction).
Week 12
Change From Baseline to 12 Week Endpoint in Total and Subdomain Scores of the Self-Esteem and Relationship (SEAR) Questionnaire
Zeitfenster: Baseline, Week 12
SEAR measures improvement in self-esteem and relationship satisfaction. Questionnaire consists of two domains, Sexual Relationship (items 1-8) and Confidence (items 9-14). All questions except negatively worded questions 8 and 11 are scored from 1=almost never/never to 5=almost always/always. Questions 8 and 11 were reverse scored, thus a higher score signifies a more favorable response for all 14 items. Overall score is transformed into a 0 (least favorable) to 100 (most favorable) scale.
Baseline, Week 12
Change From Baseline to 12 Week Endpoint in International Index of Erectile Function (IIEF), Orgasmic Functions (OF)
Zeitfenster: Baseline, Week 12
Self-reported overall satisfaction over the past 4 weeks. Scores range from 0 (low/no satisfaction) to 5 (high satisfaction), thus the 2 questions of the IIEF-OF domain range from 0 to 10.
Baseline, Week 12
Change From Baseline to 12 Week Endpoint in International Index of Erectile Function (IIEF), Sexual Desire (SD)
Zeitfenster: Baseline, 12 weeks

Baseline, 12 weeks
Change From Baseline to 12 Week Endpoint in International Index of Erectile Function (IIEF), Intercourse Satisfaction (IS)
Zeitfenster: Baseline, Week 12
Self-reported intercourse satisfaction over the past 4 weeks. Scores range from 0 (low/no satisfaction) to 5 (high satisfaction), thus the 3 questions of the IIEF-IS domain range from 0 to 15.
Baseline, Week 12
Change From Baseline to 12 Week Endpoint in International Index of Erectile Function (IIEF), Overall Satisfaction (OS)
Zeitfenster: Baseline, 12 weeks
Self-reported overall satisfaction over the past 4 weeks. Scores range from 0 (low/no satisfaction to 5 (high satisfaction), thus the 2 questions of the IIEF-OS domain range from 0 to 10.
Baseline, 12 weeks
Change From Baseline to 12 Week Endpoint in Sexual Encounter Profile (SEP) Question 1 Percentage of "Yes" Responses
Zeitfenster: Baseline, 12 weeks
Assessed was the mean change from baseline in the percentage of Yes responses to the SEP diary Question 1. "Were you able to achieve at least some erection (some enlargement of the penis)? " Data are presented as the mean percentage of yes responses per participant.
