In a three-arm, randomized trial, the investigators will test the use of HIV-1 self-testing to decrease the frequency and burden of clinic visits for PrEP while resulting in equivalent PrEP adherence and HIV testing.
Guidelines recommend HIV-1 testing quarterly for individuals on PrEP. Clinic-based HIV testing every three months is costly for both clinics and participants. The investigators propose using HIV self-testing to replace quarterly clinic-based HIV testing for participants on PrEP, eliminating half of clinic visits and saving staffing and participant costs. The investigators want to understand the effect that reduced clinic contact frequency (resulting from HIV self-testing) has on PrEP adherence or completion of HIV-1 testing, overall and in subgroups. The investigators will enroll roughly 495 eligible individuals on PrEP: 165 men and 165 women in HIV-1 serodiscordant couples and 165 women at risk of HIV-1 infection (priority populations for PrEP delivery in Kenya and more generally in Africa). In this study, participants will be randomly assigned in a 2:1 fashion to either six-monthly clinic visits or quarterly clinic visits. Participants randomized to six-monthly clinic visits will receive a 6-month supply of PrEP and either two blood-based HIV self-tests (blood-based HIV self-testing arm) or two oral fluid HIV self-tests (oral fluid HIV self-testing arm). Participants randomized to quarterly clinic visits will receive a 3-month supply of PrEP and get tested for HIV by a healthcare professional at the clinic (standard of care arm) Study outcomes, measured at Months 6 and 12, include PrEP adherence (defined as the detection of PrEP in dried blood spots as well as persistence in refilling PrEP), HIV-1 testing, and safety (including side effects and social harm).

Number of Participants With Adherence to PrEP at 6 Months
Laboratory tests will be conducted to measure adherence to PrEP medication by testing drug levels in the collected blood specimen. The detection of PrEP in blood will be considered as adherent to PrEP.
Time frame: Month 6
Persistence in Refilling PrEP
The percentage of participants that return to clinic to refill their PrEP medication. An alternative measure of PrEP adherence.
Time frame: Month 6
HIV-1 Testing
Self-reported HIV-1 testing in the past 6 months
Time frame: Month 6
PrEP Adherence
Laboratory tests will be conducted to measure adherence to PrEP medication by testing drug levels in the collected blood specimen. The detection of PrEP in blood will be considered as adherent to PrEP.
Time frame: Month 12
Persistence in Refilling PrEP
The percentage of participants that return to clinic to refill their PrEP medication. An alternative measure of PrEP adherence.
Time frame: Month 12
HIV-1 Testing
Self-reported HIV-1 testing in the past 6 months
Time frame: Month 12
