Summary

This study tests a mobile app called LOTUS designed to help people who use drugs engage with HIV prevention services like testing and PrEP. The app provides tips, reminders, peer support, and a way to ask healthcare professionals questions. The trial will enroll 40 participants to see if the app is feasible, acceptable, and shows early signs of improving prevention service use.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: LOTUS mobile app (behavioral intervention)
What this could lead to: If it works, this could point toward a scalable way to improve HIV prevention among people who use drugs.
What could go wrong: This is a very small early trial (40 people) with no control group, so results may not be generalizable. The app may not be engaging enough to change behavior.
