Primary Outcomes (1)

  • The primary measures of efficacy in this study will be improved success of erection maintenance in men with ED and improvement in female partner's sexual quality of life.

    Weeks 0 -12

Secondary Outcomes (8)

  • SEP3 at weeks 4 and 12 of treatment compared to placebo.

    Weeks 4 and 12

  • Additional Patient Diary questions at 4 weeks, 8 weeks, 12 weeks, LOCF, and over entire treatment period compared to placebo. Per-subject success rates will be calculated as the number of successes divided by the number of sexual attempts with a resp

    Weeks 4, 8 and 12

  • Global assessment question (GAQ) at weeks 4 and 12 of treatment compared to placebo

    Weeks 4 and 12

  • Global confidence question (GCQ) at 12 weeks of treatment compared to placebo.

    Week 12

  • The score for the IIEF questionnaire EF domain (IIEF-EF) at weeks 4, 12, and LOCF of treatment compared to placebo

    Weeks 4 and 12

  • +3 more secondary outcomes

Eligibility Criteria

Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Males who have had ED for at least six months according to the National Institutes of Health (NIH) Consensus Conference December 7-9, 1992 (inability to attain and/or maintain penile erection sufficient for satisfactory sexual performance).
  • Stable, heterosexual relationship for more than 6 months.
  • Males 18 years, and older.
  • Written informed consent obtained.
  • The subject and his female partner must make at least four attempts at sexual intercourse on four separate days during the untreated baseline period (according to the answer to the following question in the Patient Diary: "Was sexual activity initiated with the intention of intercourse?").
  • At least 50% of attempts at sexual intercourse during the untreated baseline period must be unsuccessful, according to the following questions from the subject diary (at least one question should be answered "No"): "Were you able to achieve at least some erection (some enlargement of the penis)?"; "Were you able to insert your penis in your partner's vagina?"; "Did your erection last long enough for you to have successful intercourse?".

You may not qualify if:

  • A) Previous or current medical conditions:
  • Any unstable medical, psychiatric, or substance abuse disorder that in the opinion of the Investigator is likely to affect the subject's ability to complete the study or precludes the subject's participation in the study.
  • Presence of penile anatomical abnormalities (e.g. penile fibrosis or Peyronie's disease) which, in the Investigator's opinion, would significantly impair erectile function.
  • Primary hypoactive sexual desire.
  • Spinal cord injury.
  • History of surgical prostatectomy (excluding TURP).
  • Retinitis pigmentosa.
  • Unstable angina pectoris.
  • History of myocardial infarction, stroke or life-threatening arrhythmia within the prior 6 months.
  • Uncontrolled atrial fibrillation/flutter at screening (ventricular response rate \≥ 100 bpm).
  • Severe chronic or acute liver disease, history of moderate or severe hepatic impairment.
  • Clinically significant chronic haematological disease which may lead to priapism such as sickle cell anemia and leukemia.
  • Bleeding disorder.
  • Significant active peptic ulcer disease.
  • Resting hypotension (a resting systolic blood pressure of \< 90 mm Hg) or hypertension (a resting systolic blood pressure \> 170 mm Hg or a resting diastolic blood pressure \> 110 mm Hg).
