Can a phone app help young adults with HIV stay on track?
NCT ID NCT07804602
First seen Sep 04, 2026 · Last updated Sep 04, 2026
Summary
This trial tests whether a smartphone app called PL4Y can help young adults aged 18 to 29 who have HIV stay engaged in their care. For the first 6 months, participants receive standard care. Then they get the app, which sends daily medication reminders, appointment alerts, secure messages with their clinic, and access to an anonymous support group. The main goal is to see if using the app helps more participants achieve viral suppression, meaning a very low level of HIV in the blood, after 12 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PositiveLinks for Youth (PL4Y), a smartphone app with daily adherence check-ins, appointment reminders, secure messaging with providers, and an anonymous virtual support group
- What this could lead to
- If it works, the app could become a practical tool to help young adults with HIV stick to their care plan and improve their long-term health.
- What could go wrong
- The trial is early and relies on participants consistently using the app, which may not happen. The app's benefits beyond standard care are not yet proven.
