3.Diagnosed with PE according to DSM IV criteria.
4. Diagnosed with PE according to the ISSM definition, that is, he ejaculates always or nearly always prior to or within about one minute of vaginal penetration; and is unable to delay ejaculation on all or nearly all vaginal penetrations; and experiences negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy.
5. Subject has lifelong PE.
6.Subject response to Screening Visit 1 PEP as follows:
a.Perceived control over ejaculation of ‘Poor’ or ‘Very poor’
b.Personal distress related to ejaculation of ‘Quite a bit’ or ‘Extremely’
c.Interpersonal difficulty related to ejaculation of ‘Quite a bit’ or ‘Extremely’
d.Satisfaction with sexual intercourse of ‘Poor’ or ‘Very poor’.
7.Subject must be in a stable heterosexual and monogamous relationship of at least 3 months duration with this partner.
8.Subject has at least documented 3 sexual encounters in the Baseline period.
9.IELT = 1 minute in at least 2 of the first 3 sexual encounters in the Baseline period.
10.The subject’s partner must provide written informed consent, be aged 18 years or over and willing to comply with the study procedures.
Are the trial subjects under 18? no
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
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range
1.Subject, or his sexual partner, has received an investigational (non-registered) drug within 30 days of Screening.
2.Subject has erectile dysfunction, defined as an IIEF5 score of =21, unless the low score is entirely related to PE symptoms in the opinion of the Investigator.
3.The subject, or his sexual partner, has a physical or psychological condition that would prevent them from undertaking the study procedures, including, but not limited to, the following:
-Urological disease (e.g. prostatitis, urinary tract infection) or genito-urinary surgery within 8 weeks of Screening
-Ongoing significant psychiatric disorder (e.g. bipolar disease, depression / anxiety disorder or schizophrenia) not controlled by medication.
4.Subject has safety testing abnormalities at the Screening Visit, in particular liver function tests, that are indicative of a medical condition that would preclude further participation in the opinion of the Investigator.
5.Subjects taking tricyclic antidepressants, monoamine oxidase inhibitors (MAOIs) or selective serotonin reuptake inhibitors (SSRIs), for indications other than PE, where the dose has been changed within 4 weeks of Screening and it is planned that the dose will change during the double-blind treatment period.
6.Subject has received any treatment for PE e.g. anti-depressant therapy, local anesthetic spray, intra-cavernosal injection or psychotherapy within 4 weeks of Screening.
7.Subject, or his sexual partner, has a current history of alcohol or drug abuse, in the opinion of the Investigator.
8.The subject, or his sexual partner, is unlikely to understand or be able to comply with study procedures, for whatever reasons.
9.Subject or his sexual partner has known drug sensitivity to amide-type local anesthetics.
10.Subjects with pregnant partners.
11.Subject with sexual partners of child-bearing potential and not using appropriate contraception [hormonal contraception or intra-uterine device (IUD) during double-blind part of study; hormonal contraception or IUD or condom during open-label part of study].
12.Subject, or his sexual partner, has a history of Glucose-6-Phosphate Dehydrogenase (G-6-PD) deficiency or use of medications that would increase susceptibility to methemoglobinemia (e.g. anti-malarial agents).
13. Subject, or his sexual partner, uses class I (e.g. mexiletine, tocainide) or III (e.g. amiodarone, sotalol) anti-arrhythmic drugs.

Name Time Method Main Objective: To determine the effect of PSD502 on the Index of Premature Ejaculation (IPE) and intravaginal ejaculatory latency time (IELT).;Secondary Objective: To evaluate safety and tolerability of PSD502 in subjects with PE, and their sexual partners. <br>;Primary end point(s): The primary efficacy variables are the:<br>•Change in mean IELT from Baseline to during the 3 months of double-blind treatment<br>•Change in the IPE domain of ejaculatory control from Baseline to month 3<br>•Change in the IPE domain of sexual satisfaction from Baseline to month 3.<br>
