What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants Experiencing at Least One Treatment Emergent Adverse Event (Serious or Non-Serious)	A Treatment Emergent Adverse Event (TEAE) was defined as an event that first occurs or worsens (increases in severity) after baseline, regardless of causality or severity. The percentage of participants with TEAEs was calculated by dividing the number of participants with at least 1 TEAE over the 12-Month treatment period by the total number of participants analyzed, multiplied by 100%. A summary of serious and other non-serious adverse events, regardless of causality, is located in the Reported Adverse Events module.	Baseline through Month 12
Percentage of Participants Experiencing at Least One Adverse Event Leading to Discontinuation	Data presented are the number of participants who experienced 1 or more AEs (all causalities and drug-related) and serious AEs (SAEs) that lead to discontinuation. A summary of serious and other non-serious adverse events, regardless of causality, is located in the Reported Adverse Events module.	Baseline through Month 12

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in the International Index of Erectile Function- Erectile Function (IIEF-EF) Domain Questionnaire Score	IIEF- EF is the sum of Questions 1-5 and 15 of the IIEF. Questions 1-5 are scored 0 (no sexual activity for Question 1, no sexual stimulation for Question 2 and did not attempt intercourse for Questions 3-5) to 5 (high erectile function) and Question 15 is scored 1 (very low confidence) to 5 (very high confidence), for a total score ranging from 1 to 30. Higher scores represent better erectile function. Least Squares (LS) mean of the change from baseline is from Mixed effect Model Repeat Measurement (MMRM) model. The model included covariates baseline + visit + pooled investigator + baseline*visit, where participant is a random effect.	Baseline, Month 1; Baseline, Month 3
Change From Baseline in the IIEF-EF Domain Questionnaire Score of 5 mg Tadalafil Treatments	IIEF- EF is the sum of Questions 1-5 and 15 of the IIEF. Questions 1-5 are scored 0 (no sexual activity for Question 1, no sexual stimulation for Question 2 and did not attempt intercourse for Questions 3-5) to 5 (high erectile function) and Question 15 is scored 1 (very low confidence) to 5 (very high confidence), for a total score ranging from 1 to 30. Higher scores represent better erectile function. Least Squares (LS) mean of the change from baseline is from Mixed effect Model Repeat Measurement (MMRM) model. The model included covariates baseline + visit + pooled investigator + baseline*visit, where participant is a random effect.	Baseline, Month 6; Baseline, Month 12;Baseline, Month 18; Baseline, Month 24
Percentage of Participants With "Yes" Responses to Sexual Encounter Profile (SEP) Diary	Participant-assessed diary has 5 questions(QI-Q5): 4 of the 5 questions were analyzed. Q2: successful penetration, Q3: successful intercourse, Q4: satisfied with erection, and Q5: satisfied with sexual experience) for each sexual encounter made over a specified period of time. SEP Q1-Q5 scores were determined as the percentage of 'Yes' responses to each of the 5 questions out of all sexual attempts recorded during the time period.	Month 1, Month 3
Percentage of Participants Achieving Normal Erectile Functioning	Participants achieving a normal erectile functioning (defined as having an IIEF-EF Domain score of >=26) at Month 1 and Month 3.	Month 1, Month 3
Percentage of Participants Achieving Normal Erectile Functioning of 5 mg Tadalafil Treatments	Participants achieving a normal erectile functioning (defined as having an IIEF-EF Domain score of >=26) at Month 6 and Month 12.	Month 6, Month 12, Month 18, Month 24
Percentage of Participants With "Yes" Responses to Global Assessment Questions (GAQ)1 and GAQ2	Participants with "yes" responses to GAQ Question 1 (GAQ1) and GAQ Question 2 (GAQ2) of the GAQ questionnaire at Month 3 and Month 12. GAQ1: Has the treatment you have been taking during this study improved your erections? GAQ2: If yes, has the treatment improved your ability to engage in sexual activity?	Month 3, Month12, Month 24
