New app and urine test aim to boost HIV med adherence in men who use stimulants
NCT ID NCT07125235
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a program called reSTART for men living with HIV who also use stimulants. It combines a smartphone app, a urine test to check medication levels, and motivational messages to help them remember to take their HIV drugs. The goal is to see if this approach can lower their viral load and reduce stimulant use. About 270 men are being recruited for this trial.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- mobile health app and urine tenofovir self-test
- What this could lead to
- If successful, this could provide a practical tool to help men with HIV and stimulant use stay on their medication and achieve viral suppression.
- What could go wrong
- This is a relatively small, early-stage trial (270 participants) focused on a specific group, so results may not apply broadly. The intervention relies on self-monitoring, which may not work for everyone.
