Evaluation of the Performance and Acceptability of a Synthetic Polyisoprene Male Condom Compared to a Natural Rubber Latex Condom

This study is a masked (investigators, research staff), two-way crossover, randomized to sequence of use study designed to evaluate the acceptability and functional performance (breakage, slippage) of a silicone lubricated polyisoprene condom and a silicone lubricated natural rubber latex condom.

About this study

Three hundred (300) couples will be enrolled and asked to use five condoms of each of the two types of lubricated condoms to yield a potential sample size of 1500 uses for each type of lubricated condom. To minimize a potential learning effect, couples will be randomly assigned to the sequence of use of each type of lubricated condom.

The primary objective of this study is to examine the slippage, breakage and acceptability of a new polyisoprene male condom compared to a natural rubber latex condom. The study will assess safety in terms of adverse events and user acceptability will be evaluated by comparing physical attributes of the polyisoprene and latex control condoms, as well as perceptions about using the devices.

Treatment and study plan

Silicone Lubricated Synthetic polyisoprine condom

Device

Synthetic polyisoprene condom are made from softer materials for a more natural feel and increased sensitivity

Silicone Lubricated Natural Rubber Latex Condom

Device

Natural rubber latex condoms are made from natural rubber

Primary outcomes

  1. Total Clinical Failure

    Time frame: 5 -7 weeks

    The total clinical failure rate is defined as the number of condoms that broke or slipped completely off the penis during intercourse or withdrawal over the number of condoms used for vaginal intercourse.

Secondary outcomes

  1. Clinical Breakage

    Time frame: 5 - 7 weeks

    The clinical breakage rate is defined as the number of condoms that broke during intercourse or withdrawal over the number of condoms used for vaginal intercourse.

  2. Clinical Complete Slippage

    Time frame: 5-7 weeks

    The clinical complete slippage rate is defined as the number of condoms that slipped completely off the penis during intercourse or withdrawal over the number of condoms used for vaginal intercourse
