Background: approximately 200,000 South Africans acquired HIV in 2021 despite universal HIV test and treat (UTT) and Pre-Exposure Prophylaxis (PrEP). Methods: we conducted a 2x2 factorial open label randomised controlled trial. N=3000 potentially eligible 16-29-year-olds, randomly sampled from a population surveillance area in a mostly rural part of KwaZulu-Natal, were randomised to one of 4 arms: 1) enhanced Standard of Care (SoC): access to mobile youth-friendly services for differentiated HIV prevention (condoms, UTT, PrEP if eligible); 2) Sexual and Reproductive Health (SRH): baseline self-collected specimens for sexually transmitted infection testing and referral to differentiated HIV prevention services; 3) Peer-support: referral to a peer navigator for support, condom provision and facilitation of attendance for differentiated HIV prevention services; 4) SRH + peer-support. Co-primary effectiveness outcomes were: 1) linkage to differentiated HIV prevention services within 60 days of enrolment; 2) transmissible HIV (HIV viral load ≥400 copies/mL) measured from dried blood spots (DBS) at 12 months. 3) the proportion of sampled individuals who consented to participation and gave a DBS for HIV testing at 12 months. Logistic regression was used for analyses, adjusted for age, sex and rural/peri-urban area. Findings: between March 2020 and August 2022, 1743/2301(76%) eligible individuals were enrolled, with a 12-month DBS collected from 1168 (67%). Baseline characteristics and 12-month outcome ascertainment were similar by arm. 755 (43.3%) linked to services by 60 days; SRH increased linkage (aOR 1.68;95%CI=1.39-2.04) but peer-support had no effect. At 12 months, 227 (19%) tested ELISA-positive for HIV, of whom 41 (18%) had a viral load ≥400 copies/ml. The overall prevalence of transmissible HIV was 3.5%. There was no evidence of an effect of either intervention on transmissible HIV (main effects: SRH aOR 1.12; 95%CI=0.60-2.11; peer-support aOR 1.03; 95%CI=0.55-1.94).
