Description of intervention(s) / exposure
Hydrogel Male Condom (Geldom)

This study is an open label, two-way crossover study, randomised to sequence of use, designed to describe the preference, and acceptability and performance of an investigational experimental male condom (Geldom) compared to a commercial latex male condom.
This study will evaluate user experience and evaluate the performance of the Geldom through comparison with a commercial latex competitor condom, describe some initial preference measures, clinical slippage and breakage rates and user acceptability. These data inform baseline measures and effect size used for the design of the future regulatory studies for registration.
The sample will be drawn from healthy young to middle aged (18-45 years) heterosexual, mutually monogamous couples and sample size of 35 couples.
To minimise a potential learning effect, couples will be randomly assigned to the sequence of use of condom type (Geldom condom then commercial latex condom or commercial latex condom then Geldom condom). The participants will use 3 Geldom condoms and 3 latex condoms over an estimated 4 week period. Participants will use all 3 of one type of condom before crossing over to the next condom. At their enrollment visit participants will receive three condoms of the first type of study condom based on their randomisation group and study lubricant (silicone and water based).

Participants will take the condoms home for use in their own environment and scheduled for their visit 2 in 14 days (+/- 2 days). At visit 2 they will receive a supply of 3 condoms of the second type of condom according to their randomisation, additional study lubricant and will be scheduled for their exit visit within two weeks.
Participants are required to complete the following activities as part of this study:
1. Have penile-vaginal intercourse 6 times while using either the Geldom or commercial latex condom
2. Return any open and unopened condom packets
3. Measure flaccid and erect penis (males only)
4. Complete questionnaires on the experience of the condoms used after each use and less than 12 hours after intercourse.

Couples will be taught the correct way to use the study condoms and provided instructions for use and how to dispose of used condoms.

There are no restrictions on the time that must elapse between use of the condoms. There is no 'wash-out' period required for cross-over between the different types of condoms other than that of the time between the last condom used from visit 1 and using the first condom provided at visit 2,

Adherence to use is monitored via the tracking of returned opened and unopened packets against the Investigational Product tracking log.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation was not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple - Odd and Even allocation
Odd participant id numbers will be assigned Geldom first then cross over to latex condom
Even participant id numbers will be assigned latex condom first then cross over to Geldom condom
Couples are assigned the same id number and distinguished by their suffix of M for Male and F for Female. EG 001M and 001F is one couple, two participants.
Masking / blinding
