Summary

This study tests a mobile app called KIOS that gives personalized advice and support to people receiving medication-assisted treatment for opioid use disorder. Over 12 weeks, 116 participants will either use the app plus standard counseling or just standard counseling. The goal is to see if the app helps them stay in treatment and reduce opioid use.

What this could mean

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

Active substance
KIOS mobile app
What this could lead to
If it works, this could provide a convenient, on-demand tool to help people stick with medication-assisted treatment and reduce opioid use.
What could go wrong
This is a relatively small, early-stage trial (116 participants) testing a behavioral app, not a drug. Results may not apply broadly, and the app's benefit over standard counseling is uncertain.
