Study summary

Premature ejaculation (PE) is a common disease in the andrology clinic. Currently, the effectiveness and outcome differences of drug treatment still need to be studied and demonstrated. Premature ejaculation concurrent with erectile dysfunction (ED) is common in outpatient clinics. The preferred treatment plan for these patients still needs to be further studied and explored, and the difference in the efficacy of different treatment regiments remain to be evaluated.

What researchers measure

Primary outcomes

  1. The change of Premature Ejaculation Profile (PEP) at week 8

    The PEP is a 4-question PRO that asks a respondent about his subjective sense of control over ejaculation, distress related to PE, interpersonal difficulty and satisfaction with sexual intercourse.

    Time frame: Baseline, Week 8

  2. The change of International Index of Erectile Function -5(IIEF-5) at week 8

    Time frame: Baseline, Week 8

Secondary outcomes

  1. Incidence of adverse reactions

    To observe the safety of the two regiments in PE concurrent with ED patients

    Time frame: Baseline, Week 8

  2. The change of Erection Hardness Score (EHS)

    Erection Hardness Score as a self-reporting measure that scored erection hardness on a 4 point scale. The aim was to help men, their partners and doctors diagnose erectile dysfunction.

    Time frame: Baseline, Week 8

  3. Clinical Global Impression of Change (GICC)

    Clinical Global Impression is a 7 point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention.

    Time frame: Baseline, Week 8

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 24, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
