Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Addiction to methamphetamine is a serious health problem in the United States. Right now, there are no medications that a doctor can give someone to help them stop using methamphetamine. More research is needed to develop drugs for methamphetamine addiction. Ibudilast (the study drug) is a drug that could help people addicted to methamphetamine.
