Brief Summary
The purpose of the study is to evaluate the functional performance and acceptability of the Miss Liberty female condom version 1 (Miss Liberty female condom), compared to the FC2 female condom. The study will be a sequential randomised 2-period cross-over trial comparing five uses of the Miss Liberty female condom, compared to the control FC2 female condom. Each woman will be asked to use five Miss Liberty female condoms, and five FC2 control female condoms in a randomised order. Woman will complete a Condom Use Report after each condom use. Function, safety, and acceptability will be assessed at each of two follow-up visits conducted after using each set of five condoms. The trial will enrol 235 women between 18-45 years old. The primary objective is to ascertain the functional performance of the Miss Liberty female condom compared to the control FC2 female condom. The secondary objectives are to determine the acceptability and safety (as determined by the number of adverse events) for the Miss Liberty female condom compared to the FC2 female condom.

Outcome Measures
Primary Outcomes (5)
Clinical breakage
Defined as breakage or tearing of the female condom during sexual intercourse or during withdrawal from the vagina. Clinical breakage is breakage with potential adverse clinical consequences. The clinical breakage rate is calculated by dividing the number of female condoms reported to have broken or torn during sexual intercourse or during withdrawal by the number of female condoms used during sexual intercourse.
2-3 months
Clinical slippage
Defined as an instance when a female condom slips completely out of the vagina during sexual intercourse. The clinical slippage rate is calculated by dividing the number of female condoms that slipped by the number of female condoms used during sexual intercourse.
2-3 months
Clinical misdirection
Defined as vaginal penetration whereby the penis is inserted between the female condom and the vaginal wall. The clinical misdirection rate is calculated by dividing the number of reported events of misdirection by the number of female condoms used during sexual intercourse.
2-3 months
Clinical invagination
Defined as an instance when the external retention feature of the female condom is partially or fully pushed into the vagina during sexual intercourse. The clinical invagination rate is calculated by dividing the number of events of invagination by the number of female condoms used during sexual intercourse.
2-3 months
Total clinical failure
Defined as the sum of female condoms with at least one clinical failure event (clinical breakage, clinical slippage, clinical misdirection, clinical invagination) clinically break or additional failure modes(s) identified in the risk assessment which results in the reduction of the female condom protective function. The total clinical failure rate is calculated by dividing the number of female condoms with a clinical failure by the number of female condoms used during sexual intercourse.

Study Arms (2)
Arm 1 - Type A - Type B
ACTIVE COMPARATORA separate randomization process (implemented by an independent statistician) will allocate one of the two study condom types to the letters A and B which will be used to label individual packs of five condoms for distribution to study women and to record the condom type used in each study period.
Arm 2 -Type B - Type A
ACTIVE COMPARATORA separate randomization process (implemented by an independent statistician) will allocate one of the two study condom types to the letters A and B which will be used to label individual packs of five condoms for distribution to study women and to record the condom type used in each study period.
Interventions
The Miss Liberty female condom is manufactured by Zhejiang Rui Bo 001 High Polymer Co, Ltd. The condom is designed as a loose-fitting pouch that lines the vagina. It has two flexible rings. The sheath, are made of polyurethane. The outer ring remains outside the vagina and covers the external genitalia during intercourse. An internal ring is removable and serves as the insertion mechanism and anchors the device within the vagina. Miss Liberty measures 180mm in length and 78mm in lay-flat width. The device is pre-lubricated with silicone oil. This condom is a similar design (material, length, width) to the USFDA approved FC1 female condom which was discontinued and replaced by FC2.
The FC2 is a second-generation female condom manufactured by the Female Health Company (Chicago, IL). The FC2 has US FDA approval and has been granted the CE Mark of the European Union. The FC2 is pre-qualified by the WHO. The condom is designed as a loose-fitting pouch that lines the vagina. It has two flexible rings. The outer ring at the open end is rolled from the nitrile material. The outer ring remains outside the vagina and covers the external genitalia during intercourse. An internal ring is removable and serves as the insertion mechanism and anchors the device within the vagina. FC2 measures 170mm in length and 80mm in lay-flat width. The device is pre-lubricated with silicone oil. This FC is available in the public health sector in South Africa.
