intention to continue with the same partner for the duration of the study)
· diagnosed with lifelong PE (defined as symptoms starting at the time the patient became sexually

· previously tried at least one form of therapy for PE (eg, behavioral therapy, topical therapy, or oral
therapy) but patient remains dissatisfied
· mean screening intravaginal ejaculatory latency time (IELT) of = 1 minute (calculated from the 4 most
recent evaluable events recorded on the screening sexual event log [SEL])
-None of the 4 most recent evaluable events can have an IELT measurement > 2 minutes.
-It must not have taken longer than 28 days to obtain 4 evaluable events.
-Evaluable event is defined as an ejaculation which was recorded in the SEL to have occurred
prior to intended vaginal penetration or during vaginal penetration (see Section 6.3.4.1 for
further details).
· patient and partner are willing and able to engage in vaginal intercourse at least 4 times per month for
the duration of the study
· patient and partner agree not to change their usual sexual practices during the study (eg, amount of
foreplay, use of lubrication, use of behavioral techniques, and/or type of contraception)
· patient and partner agree not to use condoms for the duration of the study (screening and
posttreatment)

Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 60

F.1.3.1 Number of subjects for this age range
· any medical or surgical condition that could be associated with secondary (acquired) PE or patient has
PE which is situational or attributable to relationship issues
· a score of < 25 on the International Index of Erectile Function - Erectile Dysfunction (IIEF-ED)
questionnaire at screening
· patient is unable or unwilling to discontinue (ie, washout) prohibited medications from at least 28 days
prior to efficacy measurements, and throughout the duration of the study. Prohibited medications
include:
1) dapoxetine (Priligy™, Kutub™) or any other medications with selective serotonin reuptake
inhibitor (SSRI) activity
2) tramadol or any other medications with serotonin norepinephrine reuptake inhibitor (SNRI)
activity or with opiate activity
3) antidepressant, antipsychotic, antiepileptic, neuroleptic medications, or medications with
psychoactive properties
4) topical penile treatments (eg, anesthetics, herbal treatments) for PE or any other indication
5) penile injections (eg, intracavernosal injections) for PE or any other indication
6) phosphodiesterase type 5 (PDE-5) inhibitors, alprostadil, or any other treatments for erectile
dysfunction (ED) or any other type of sexual dysfunction
7) See Section 4.5.2 for a full list of prohibited medications requiring washout.
· patient has had prior genital, prostatic or lower urinary tract surgery (other than vasectomy or
circumcision)

study
