结局指标

主要结局

Earliest Onset Day Measured by Cumulative Percentage of Participants With Yes Response to Sexual Encounter Profile Diary Question 3

时间窗: 4 days during double-blind period

Cumulative percentage of participants achieving successful intercourse, as measured by "yes" responses to Sexual Encounter Profile diary question 3 (SEP3). SEP3 asks if the participant's erection lasted long enough to have successful intercourse.

次要结局

  • Sexual Encounter Profile Diary Question Number 1, Change From Baseline to Post Baseline During the Double-blind Period in Percentage of Yes Responses(Baseline and 14 days double-blind period)
  • Sexual Encounter Profile Diary Question Number 2, Change From Baseline to Post Baseline During the Double-blind Period in Percentage of Yes Responses(Baseline and 14 days double-blind period)
  • Sexual Encounter Profile Diary Question Number 3, Change From Baseline to Post Baseline During the Double-blind Period in Percentage of Yes Responses(Baseline and 14 days double-blind period)
  • Sexual Encounter Profile Diary Question Number 4, Change From Baseline to Post Baseline During the Double-blind Period in Percentage of Yes Responses(Baseline and 14 days double-blind period)
  • Sexual Encounter Profile Diary Question Number 5, Change From Baseline to Post Baseline During the Double-blind Period in Percentage of Yes Responses(Baseline and 14 days double-blind period)
  • Sexual Encounter Profile Diary Question 3, the Overall Distribution of Time to Onset by Yes Responses(4 days double-blind period)
  • Sexual Encounter Profile Diary Question 3, Daily Cumulative Percentage of Successful Intercourse Attempts(14 days during double-blind period)
  • Sexual Encounter Profile Diary Question 3, Percentages of Yes Responses During the Double-blind and Open-label Periods for Participants Who Were Assigned to Placebo in the Double-blind Treatment Period(14 days double-blind and 14 days open-label)
  • Sexual Encounter Profile Diary Question 3, Percentages of Yes Responses in the Double-blind Period and the Open-label Period for Participants Who Were Assigned to Tadalafil 2.5 mg in the Double-blind Treatment Period(14-day double-blind and 14-day open-label)
  • Sexual Encounter Profile Diary Question 3, Percentages of Yes Responses in the Double-blind Period and the Open-label Period for Participants Who Were Assigned to Tadalafil 5 mg in the Double-blind Treatment Period(14-day double-blind and 14-day open-label)
  • Sexual Encounter Profile Diary Question 3, Percentages of Yes Responses During the Double-blind Period and the Open-label Period for Participants Who Didn't Respond to Tadalafil 2.5 mg During Double-blind Period(14 days double-blind and 14 days open-label)
