Enhanced HIV Prevention in Couples: Feasibility Study #3

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to gather information needed to develop a large prevention trial to decrease risk for Human Immunodeficiency Virus (HIV) transmission among HIV-discordant couples (where one person is HIV-positive and the other is HIV-negative) in Lesotho. The protocol team would like to explore new strategies for increasing the number of partners who receive an HIV test and whether this increase in testing also results in identifying HIV-discordant couples. These couples would be the focus of the future large prevention trial, therefore it is critical that the protocol team explore effective strategies for identifying and recruiting these couples. Men and women (index participants) who are attending Antenatal Care (ANC),Tuberculosis (TB) and antiretroviral therapy (ART) clinics will be recruited for this study. If they agree to take part, a testing team will visit their household and offer all adults staying in the house the opportunity to conduct a self-test for HIV. Seventy-ﬁve index participants will be enrolled into the study and have their homes visited by the testing team. The number of household members tested will depend on the number of people living in each household.

Detailed Description
-----------------
In Lesotho, a country with estimated 16% discordance among heterosexual couples, reaching male partners and couples in order to engage them in HIV testing to enable identiﬁcation of discordant couples is an important ﬁrst step for any HIV prevention and treatment efforts. This is a feasibility study of the use of home-based HIV self-testing of partners and household members of individuals recruited from select Antenatal Care (ANC), Tuberculosis (TB) and antiretroviral therapy (ART) clinics in Lesotho. This study uses an observational design to evaluate the feasibility and acceptability of home-based self-testing for HIV testing of partners and the effectiveness of this intervention to identify HIV discordant couples. It is hypothesized that a home-based self-testing intervention will increase the number of partners testing for HIV and will result in increased identiﬁcation of newly diagnosed HIV-discordant couples, the target population of the planned Enhanced Prevention in Couples (EPIC) study. Primary objectives of this study include: To evaluate the feasibility and acceptability of home-based self-testing for HIV testing of partners of index participants To evaluate the effectiveness of home-based partner self-testing strategies to identify HIV-discordant couples To evaluate the feasibility and acceptability of home-based self-testing for HIV testing of other household members of index participants Seventy-ﬁve men and women (index participants) will be recruited from antenatal, TB and ART clinics. HIV testing teams will visit index participant households and offer home-based HIV testing to all adult household members.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Home-based Self-testing<br>Index participants who have tested positive for HIV will be provided with information regarding the importance of HIV testing for their partners and other household members and the role of home-based self-testing in potentially increasing the number of partners and household members tested for HIV. In addition, index participants will be counseled about ways in which to talk to partners and household members about HIV testing and provided with information sheets that can be distributed within the household. Lastly, index participants will be introduced to a member of the testing team that will present at their home and offer the study intervention. | Other: HIV Self-testing with Standard Counseling and Testing (SCT) Confirmation<br>* Partners of the index participants and other household members will be offered HIV self-testing by the mobile testing team. Those who consent to HIV self-testing with SCT confirmation will complete the following procedures: Undergo standardized pre-test counseling and demonstration of use of HIV rapid test kit by trained study staff, including how to determine test results Self-administer HIV rapid test and read test results Provide study staff with self-testing result Undergo confirmatory testing as well as post-test counseling by study staff (SCT) if the initial self-test is positive, there is any doubt about the results, or the test reveals couple discordance<br>* Other names: Self-testing with SCT;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of partners tested | Consistent with the primary study objectives of this study, we will evaluate the feasibility of a home-based HIV self-testing strategy by monitoring the number of partners being tested for HIV. | 9 months | 
| Number of household members tested | Consistent with the primary study objectives of this study, we will evaluate the feasibility of a home-based HIV self-testing strategy by monitoring the number of members of the index participants' households being tested for HIV. | 9 months | 
| Number of sero-discordant couples identified | We will evaluate the effectiveness of a home-based HIV self-testing strategy by tracking the number of HIV-serodiscordant couples that are identified throughout this study. | 9 months |
