A Clinical Investigation to Assess the Performance of a Polyurethane Condom Versus a Latex Condom in Healthy Monogamous Couples

Phase 4

Completed

• Conditions: Control of Pregnancy; Prevention of Sexually Transmitted Infections
• Interventions: Device: Polyurethane (PU) condom; Device: Natural Rubber Latex (NRL) condom

• Registration Number: NCT04134039
• Lead Sponsor: Reckitt Benckiser Healthcare (UK) Limited

Brief Summary

This investigation is designed to evaluate the performance rate of a polyurethane (PU) condom versus a standard natural rubber latex (NRL) condom.

Detailed Description

In this clinical investigation, a new PU male condom (test condom) will be evaluated against a marketed NRL male condom (reference condom). This clinical investigation will also evaluate the in-use tolerance of the test and reference condoms.

Inclusion Criteria

1. A male and a female subject aged: 18 - 60 years inclusive.
2. All subjects must be generally healthy and in a mutually monogamous heterosexual relationship - current relationship ≥ 3 months.
3. All couples must be sexually active and agree to have penile-vaginal intercourse with a frequency sufficient to meet protocol requirements (a minimum of 5 coital acts over 4 weeks).
4. The female partner should already be on an established highly effective form of non-barrier contraception, unless post-menopausal.
5. Couples must agree not to use drugs or non-investigational devices that can affect sexual performance.

Main

Exclusion Criteria

1. Either partner is or becomes aware of an allergy or sensitivity to the ingredients of the test products, including the test or reference condoms.
2. Either partner has a pre-existing skin condition (severe eczema/ psoriasis) or systemic allergic reactions or as confirmed by the subject and physical examination.
3. Either partner that needs to use condoms for a specific sexually transmitted infection (STI) protection e.g. discordance for Human Immunodeficiency Virus (HIV) or herpes.
4. Subjects that have previous or planned genital surgery, that in the opinion of the Investigator would consider the subject unsuitable to participate in the clinical investigation e.g. laser for abnormal smear.
5. Male partners that have known erectile or ejaculatory dysfunction.
6. A female partner that has been diagnosed with or treated for vaginal complaints (including vaginal dryness) in the previous 3 months which, in the opinion of the investigator, deems the partner unsuitable for the investigation.
7. Any subject who has clinical symptoms or signs of a sexually transmitted diseases (STD) or HIV/ AIDS or has a previous history of high-risk behaviour as judged by the investigator.
8. Female partner using medication which in the investigator's opinion would affect vaginal mucosal secretion, such as Chlorpheniramine at any time in the 14 days (or 5 half-lives of the drug, whichever is longer) before first condom use.
9. A male partner with abnormal penile anatomy that would, in the opinion of the investigator, affect the ability to keep the condom in place during intercourse.
10. Either partner intends to continue to use antihistamines, anti-inflammatory drugs or pain killers for the duration of the investigation.

Arm && Interventions

Group	Intervention	Description
Polyurethane (PU) condom	Polyurethane (PU) condom	Following randomisation each couple will be given one set of 7 condoms as per randomisation schedule. After use of at least 5 condoms, couples will return to the clinic site for collection of their next set of condoms. Each couple will test a maximum of 14 condoms during their participation in the investigation.

Primary Outcome Measures

Name	Time	Method
Compared clinical failure rate of condom use between the test condom group and the reference condom group	within 2 hours following each coital act for each condom use	Clinical failure rate is calculated as the number of condoms with at least 1 acute clinical failure event divided by the number of condoms used during intercourse, reported as a percentage. Clinical failure events, defined in ISO 29943-1:2017, will be reported by subjects.

Secondary Outcome Measures

Name	Time	Method
Performance (clinical slippage rate) of the Polyurethane (PU) condom	within 2 hours following each coital act for each condom use	Clinical slippage rate is calculated as the number of condoms with at least 1 clinical slippage event divided by the number of condoms used during intercourse, reported as a percentage. Clinical slippage events, defined in ISO 29943-1:2017, will be reported by subjects.; A clinical slippage is defined as a condom slipping off completely during intercourse or during withdrawal from the vagina. Slippage that occur because the user failed to hold onto the condom at the base of the penis during withdrawal and/ or because the user delayed withdrawal after sex are to be record as "non-clinical slippage", these events are considered user failures.
Subject's experience on the use of each type of condoms [Acceptability and Tolerability	12 weeks	Acceptability and tolerability as assessed by subject perceived questionnaires (designed by following ISO 29943-1)
Performance (clinical breakage rate) of the Natural Rubber Latex (NRL) condom	within 2 hours following each coital act for each condom use	Clinical failure rate is calculated as the number of condoms with at least 1 acute clinical failure event (clinical slippage or clinical breakage) divided by the number of condoms used during intercourse, reported as a percentage. Clinical failure events, defined in ISO 29943-1:2017, will be reported by subjects.
Incidence of treatment-emergent adverse events and adverse device effects, defined in MEDDEV 2.7/3	12 weeks
Performance (clinical breakage rate) of the Polyurethane (PU) condom	within 2 hours following each coital act for each condom use	Clinical failure rate is calculated as the number of condoms with at least 1 acute clinical failure event (clinical slippage or clinical breakage) divided by the number of condoms used during intercourse, reported as a percentage. Clinical failure events, defined in ISO 29943-1:2017, will be reported by subjects.
