Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Evaluation of safety of study drug [ Time Frame: 4 weeks ]
    Number of Participants with Abnormal Laboratory Values and/or Adverse Events That Are Related to Treatment


Secondary Outcome Measures :
  1. Evaluation of change in Intra-vaginal Ejaculation Latency Time (IELT) compared to baseline [ Time Frame: 4 weeks ]
    Intra-vaginal ejaculation latency time difference of one minute or more will be considered as efficient.

  2. Evaluation of IIEF-15 (International Index of Erectile Function) score compared to baseline [ Time Frame: 4 weeks ]
    Increase in IIEF score will be considered as efficacy.

  3. Evaluation of premature ejaculation symptom scores compared to baseline [ Time Frame: 4 weeks ]
    Increase in IIEF scores will be considered as efficacy.
