SABES?: HIV Test and Treat to Prevent HIV Transmission Among MSM and Transgender Women
Study Details
Study Description
Brief Summary
This study will recruit men and transgender women with acute or recent HIV infection. It wil look at how HIV medicines (ART) when given very early after HIV infection affect the amount of HIV in the blood, semen and rectal secretions. In addition, Investigators will be using modeling studies to look at whether or not this kind of HIV treatment can decrease the risk that a man will infect a person he has sex with and to find out how failure to take medications will impact spreading the virus to other people.
In this study, one group will be randomized (like a coin toss) to start ART immediately (just at the time of the enrollment visit) and the other group will wait until week 24 of the study to start ART. Both groups will be followed for a total of 48 weeks and will continue to receive ART from local sources after the study is over.

Detailed Description
This is three-step study. Step 1 will screen men who have sex with men (MSM) and transgender women who are unaware of their HIV status and 1) report high risk behaviors for acquiring HIV-1 infection or 2) who have symptoms of acute retroviral syndrome or 3) who have a sexual partner with newly-diagnosed acute or recent HIV infection. HIV testing will be conducted for several thousand MSM and transgender women from study opening until July 2015. In Step 2, high risk HIV-1 uninfected MSM and transgender women with high risk for acquiring HIV will be tested at regular intervals for incident HIV-1 (using tests for HIV p24 and/or HIV RNA). (During this period, men will receive standard HIV prevention interventions.) In Step 3, individuals with acute or recent HIV-1 infection will be enrolled in a 48-week randomized, open-label study of the effects of immediate vs. deferred ART on the decay dynamics of HIV viral load in plasma, semen and rectal secretions. (ART will be provided prior to 24 weeks for any participant in the deferred ART arm who meets initiation criteria.) All participants will be followed for 48 weeks after which they will continue ART from other sources.

Outcome Measures
Primary Outcome Measures
- HIV viral load [four years]
To quantify HIV viral load in plasma, semen and rectal secretions in individuals with early HIV infection in immediate versus deferred treatment groups.
Secondary Outcome Measures
- Risk factors for acute/recent HIV infection [four years]
To identify risk factors associated with incident HIV-1 infection among MSM and transgender women in Peru.
- Linkage to care [four years]
To determine the proportion of individuals with evidence of acute infection (HIV-1 RNA-positive) who are successfully contacted for confirmatory HIV testing and are then linked to care.
- Retention in care [four years]
To determine the proportion of men retained in care, including adherence to ART and study procedures, among individuals with early HIV-1 infection receiving immediate and deferred ART.
