Study summary

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.

Read the detailed description

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.

Exclusion criteria

Exclusion Criteria:

  • Subject, or his sexual partner, has received an (unapproved) drug within 30 days of Screening.
  • Subject has erectile dysfunction, defined as an IIEF-5 score of 21, unless the low score is entirely related to PE symptoms in the opinion of the Investigator.

  • 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.
  • Subject has received PSD502 in a clinical study or has received Fortacin within 1 year of Screening.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Study arms

  • 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.

    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).

    Drug: Placebo

Interventions

  • DrugPlacebo

    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.

  • DrugPSD502

    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.

What researchers measure

Primary outcomes

  1. Change between Baseline and 4 weeks : Success on the Premature Ejaculation Bothersome Evaluation Questionnaire PEBEQ Item 3 (event-specific bother)

    Success is defined as having a 1-point or greater improvement between the mean response over the treatment period and the mean response during the baseline period

    Time frame: Baseline and 4 week treatment period

Secondary outcomes

  1. Patient Global Impression of Change

    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?'

    Time frame: 4 weeks post treatment

  2. Patient Global Impression of Severity

    Change from baseline in patient-reported impression of severity of the quickness of their ejaculation.Subjects will be asked to answer the question 'Overall, how severe is the quickness of your ejaculation?' using a 5-point scale of 'Not Severe', 'Mildly Severe', 'Moderately Severe', 'Very Severe' and 'Extremely Severe'.

    Time frame: Baseline and 4 week treatment period

  3. Patient Global Impression of Change-Bother

    Patient-reported global impression of change in the bother resulting from the quickness of their ejaculation. Subjects will be asked to provide a response to the following question 'Compared to when you started the study, how would you describe any change in how much you are bothered by the quickness of your ejaculation now?' on a 7-point scale of: 'Bothered a great deal less', 'Bothered moderately less', 'Bothered a little less', 'Bothered about the same', 'Bothered a little worse', 'Bothered moderately worse' and 'Bothered 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?'.
