---|---|---|---|---|
Primary | Mean Fold Change in Geometric Mean Intravaginal Ejaculatory Latency Time (IELT) | IX-01 versus placebo. Intravaginal ejaculatory latency time (IELT) was defined as the time from the initiation of sexual intercourse (penetration) until ejaculation occurred | Last 4 weeks of treatment compared to baseline | |
Secondary | Proportion of Participants Rating Their PE as Better or Much Better, on the Clinical Global Impression of Change (CGIC) Scale | 7 point scale ranging from much worse (-3) to much better (3). The proportion refers to the proportion of patients who had the best 2 possible responses [better(2) or much better (3)] on this 7 point scale | Baseline to the end of treatment (approximately 8 weeks) | |
Secondary | Proportion of Participants With Greater Than or Equal to (=) 2.5 Fold Increase in Intravaginal Ejaculatory Latency Time (IELT) | Intravaginal ejaculatory latency time (IELT) was defined as the time from the initiation of sexual intercourse (penetration) until ejaculation occurred. Outcome measured proportion of patients with at least a 2.5-fold increase in geometric mean IELT over the last 4 weeks of treatment as compared to baseline. Proportion of participants adjusted for baseline IELT, country and site | Last 4 weeks of treatment compared to baseline | |
Secondary | Mean Fold Change in Arithmetic IELT (Intravaginal Ejaculatory Latency Time) | IX-01 versus placebo | Last 4 weeks of treatment compared to baseline | |
Secondary | Mean Change in Score on Control of Timing of Ejaculation | Reported in electronic diary and based on the Premature Ejaculation Profile (PEP). PEP question on control of timing is scored on a 5 point scale with the scores ranging from very poor (this is the worst answer) scored as 0 to very good (this is the best answer scored as 4) | Last 4 weeks of treatment compared to baseline | |
Secondary | Mean Change in Score on Ejaculation-related Personal Distress | Based on Premature Ejaculation Profile (PEP). Scale ranges from 'extremely' (0) to 'not at all' (4). An increase in score from baseline indicates improvement. | Last 4 weeks of treatment compared to baseline | |
Secondary | Proportion of Participants With = 1 Category of Improvement in Satisfaction With Sexual Intercourse, on the Premature Ejaculation Profile (PEP) Questionnaire | Based on Premature Ejaculation Profile (PEP) 5 point scale with the scores ranging from 0 (worse answer) to 4 (best answer). | Baseline to 8 weeks | |
Secondary | Proportion of Participants With = 1 Category of Improvement in Control Over Ejaculation During Sexual Intercourse on the Premature Ejaculation Profile (PEP) Questionnaire | Reported in electronic diary and based on the Premature Ejaculation Profile (PEP). PEP is scored on a 5 point scale with the scores ranging from 0 (worst answer) to 4 (best answer) | Baseline to 8 weeks | |
Secondary | Proportion of Participants With = 1 Category of Improvement in Ejaculation-related Distress on the Premature Ejaculation Profile ( PEP) Questionnaire | Reported in e-diary. Based on Premature Ejaculation Profile (PEP). Scale ranges from 'extremely' (0) to 'not at all' (4). An increase in score from baseline indicates improvement. | Baseline to 8 weeks | |
Secondary | Proportion of Participants With = 1 Category of Improvement in Ejaculation-related Interpersonal Difficulty on the Premature Ejaculation Profile (PEP) Questionnaire | Reported in e-diary. Based on Premature Ejaculation Profile (PEP). Scale ranges from 'extremely' (0) to 'not at all' (4). An increase in score from baseline indicates improvement. | Baseline to 8 weeks | |
Secondary | Proportion of Participants With = 2 Category Increase in Control and = 1 Category Decrease in Personal Distress on a Patient Reported Outcome (PRO) Measure | Reported in e-diary. Based on Premature Ejaculation Profile (PEP). Each of the PEP questions is scored on a 5 point scale with the scores ranging from 0 (worst answer) to 4 (best answer) | Baseline to 8 weeks | |
Secondary | Change in Percentage of Intercourse Attempts Lasting Longer Than 1 Minute From Baseline to Last 4 Weeks on Treatment | 'Baseline' time period defined as Day -28 - Day 0. 'Last 4 Weeks' time period defined as the 28 days prior to last time subject took study drug and after Day 14. Analysis excludes two subjects from ITT population: #010-012 (placebo) and #888-018 (active). Adjusted for treatment, baseline IELT, baseline percentage, country and site. |
Baseline to last 4 weeks on treatment | |
Secondary | Incidence of Treatment-emergent Adverse Events | Number of participants with at least one treatment-emergent adverse event | Start of Treatment to end of study (approximately 10 weeks) |
