- Patient Global Impression of Change [ Time Frame: 4 weeks post treatment ]
Patient-reported global impression of change in the quickness of their ejaculation. Subjects will be asked to provide a response to the question 'Compared to when you started the study, how would you describe any change in how quickly you ejaculate now?' on a 7-point scale of: 'A great deal better', 'Moderately better', 'A little better', 'About the same', 'A little worse', 'Moderately worse' and 'A great deal worse'. Subjects will also be asked to provide a 'Yes' or 'No' response to the question 'Was this a meaningful or important change for you?'

PSD502 in Subjects With Premature Ejaculation
|
A Pilot Multicenter, Randomized, Double-Blind Study Comparing The Proportion Of Responders to PSD502 and to Placebo Using the PEBEQ In Subjects With Premature Ejaculation
|
This study is being done to test the effect of PSD502 (the study medication) compared to placebo in subjects with premature ejaculation. PSD502 is a topical (applied to skin) anesthetic spray containing a mixture of two drugs called lidocaine and prilocaine that will be applied to the penis. Half of the subjects will receive PSD502 and half will receive placebo.
|
The study will assess whether the bothersome symptoms of premature ejaculation (PE) are helped when treated with PSD502 by answering questionnaires such as the 'Premature Ejaculation Bothersome Evaluation Questionnaire' (PEBEQ) and 'Index of Premature Ejaculation© (IPE) and some additional questions about premature ejaculation.
The study will also measure the effect of PSD502 on the Intravaginal Ejaculatory Latency Time (IELT). This is the time between when the penis enters the vagina and when the subject starts to ejaculate in the vagina.
Subjects are stratified based on whether they are circumcised or uncircumcised and within each stratified group subjects are randomized to PSD502 (lidocaine prilocaine spray) or placebo in a 1:1 ratio.

- Drug: Placebo
For each sexual encounter during the 4-week treatment period the study spray will be applied 5 minutes before intercourse and any excess will be wiped off prior to penetration.
Study subjects should leave at least 24 hours between each dosing.
- Drug: PSD502
For each sexual encounter during the 4-week treatment period the study spray will be applied 5 minutes before intercourse and any excess will be wiped off prior to penetration.
Study subjects should leave at least 24 hours between each dosing.
|
- Experimental: PSD502
PSD502 spray contains a eutectic-like mixture of lidocaine and prilocaine, and a propellant (norflurane) which also serves as a solvent. Each spray contains 7.5 mg lidocaine and 2.5 mg prilocaine. A single dose consists of 3 sprays applied to the glans penis.
Intervention: Drug: PSD502
- Placebo Comparator: Placebo
The placebo is a metered dose spray, identical in appearance to the active treatment and contains the same propellant (norflurane) but has no lidocaine or prilocaine (instead it contains PEG600 and Povidone).
Intervention: Drug: Placebo

- Subject, or his sexual partner, uses Class I (e.g., mexiletine, tocainide) or III (e.g., amiodarone, sotalol) anti-arrhythmic drugs, or cimetidine, beta blockers or local anesthetics.
