Awards & highlights


This trial uses MRIs to study how different types of therapy affect the brains of people with opioid addiction, in hopes of finding better treatments.

Who is the study for?
This trial is for adults aged 18-64 with heroin addiction, specifically those who have chosen heroin as their primary drug and are stabilized on methadone or similar treatments. It's not suitable for individuals with metal implants, serious medical conditions like heart disease, a history of significant head trauma, neurological diseases, schizophrenia, autism spectrum disorders, or infectious diseases such as Hepatitis B/C or HIV/AIDS.Check my eligibility
What is being tested?
The study compares two types of behavioral group therapies to see which is more effective in treating opioid addiction. Participants will undergo brain scans before and after the 8-week therapy sessions to observe changes in reward processing and impulse control. The effectiveness will be evaluated at different stages: before treatment starts, right after it ends, and three months later.See study design
What are the potential side effects?
Since this trial involves behavioral group therapies rather than medication or invasive procedures, there are no direct physical side effects associated with the interventions being tested.
