Clinical Trial Summary

The clinical study will compare two lubricated polyurethane male condoms of different thickness with a marketed lubricated control male condom made of natural rubber latex. This crossover study will randomize 300 heterosexual couples to the sequence in which they use five condoms of each of the three study condom types. The clinical failure (breakage and slippage) rates of the two polyurethane condoms will be compared to the clinical failure (breakage and slippage) rate of commercial natural rubber latex control condom using a statistical test of non-inferiority. The study will also compare the acceptability of the two polyurethane condom different thickness with that of the natural rubber latex control condom obtained from interviews and questionnaires with subject couples.

Description:

The clinical study will compare two lubricated polyurethane male condoms of different thickness and different sizes with a marketed lubricated control male condom made of natural rubber latex.

Couples entering the study will be expected to use 5 of each type of the 3 condoms in a randomised order. The identity of the condoms will be masked to both the couples and the investigators. The aim will be to recruit 300 heterosexual with the intent of achieving a minimum 1,000 uses of each condom type. Couples will report condom use events using a condom report form. The primary information collected will relate to condom breakage and slippage of the penis during use.

The total clinical failure rates (breakage and slippage) of the two polyurethane condoms will be compared to the clinical failure (breakage and slippage) rate of commercial natural rubber latex control condom using a statistical test of non-inferiority. The study will also compare the acceptability of the two polyurethane condom different thickness with that of the natural rubber latex control condom obtained from interviews and questionnaires with subject couples.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Non Inferiority Analysis of Each of the Experimental Condoms Verses the Control Condom With Respect to Clinical Failure Rates (Combined Breakage and Slippage) as Per ISO 29943-1:2017.	To confirm each experimental condom is non-inferior to the control condom with respect to total clinical failure rate. The definition of total clinical failure rate as specified in ISO 29943-1:2017 will be used. The Total Clinical Failure Rate is Defined as the Number of Condoms with at least One Acute Failure Event (e.g. Clinical Breakage or Clinical Slippage) Divided by the Number of Condoms Used During Intercourse; Typically Reported as a Percentage; Any Condom which Experiences Multiple Clinical Failure Events Only Count as a Single Clinical Failure.; To be eligible for inclusion in the non-inferiority analysis the each couple had to have used at least one of the appropriate experimental condoms and at least one control condom. This means that the numbers of participants and condoms reported in each of the two non-inferiority comparisons will differ.	Self Completion of Questionnaires Within 12 Hours of condom use. Questionnaires returned to investigators when receiving next set of 5 condoms. All sets of questionnaires returned within 9 weeks of couple starting.
