Peer support could boost HIV med adherence and curb substance use
NCT ID NCT05933226
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a program called Khanya, where trained peers (people with lived substance use experience) help HIV patients stick to their medication and reduce drug or alcohol use. The program is offered in steps: a basic version first, then a more intensive one if needed. Researchers will compare it to usual care over 12 months in South African primary care clinics. About 160 adults with HIV who have trouble taking their medication and have moderate-to-high substance use risk are taking part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Khanya (peer-delivered behavioral intervention)
- What this could lead to
- If it works, this could provide a low-cost, scalable way to improve HIV medication adherence and reduce substance use in primary care settings.
- What could go wrong
- This is a relatively small trial (160 participants) testing a behavioral intervention, so results may not apply broadly. The intervention relies on peer counselors, which may vary in effectiveness.

Inclusion Criteria: * HIV positive and on ART * ≥18 years of age * At least moderate substance use risk in the past 3 months for at least one non-tobacco substance (measured by the WHO- ASSIST: score ≥11 for alcohol, ≥4 for non-tobacco drugs) * ART nonadherence and/or risk of virologic failure, defined as at least one of the following in the past 12 months 1) re-engaging in care after ≥1 month of being out of care (confirmed by pharmacy refill data) 2) ≥1 episodes of VL \>400 copies/mL 3) on second- or third-line ARTs. Exclusion Criteria: * Severe risk/likely dependence for opiates (WHO ASSIST score \>26) because opiate substitution therapy is largely not available * Severe alcohol dependence symptoms that may warrant medical management of potential withdrawal symptoms/stabilization prior to study participation * Inability to provide informed consent or complete study procedures in isiXhosa or English * In third trimester of pregnancy during baseline * Currently enrolled in another study or treatment program focused on substance use (including Matrix) or ART adherence. * Untreated or undertreated major mental illness that would interfere with study procedures
