In the drug and alcohol treatment field, what works for one person may not work for another; and sometimes more than one type of treatment may be necessary for successful recovery. Now, there are medications for certain addictions, which can offer treatment for some people.

We’re proud to say that we have been a part of the research that has evaluated the effectiveness of medications and cognitive/behavioral treatments that have resulted in the availability of medications for alcohol and opioid dependence. Our clinical locations have functioned as clinical sites in collaboration with researchers from UCLA, NIDA, SAMHSA, and the private industry.

CLARE|MATRIX has established a reputation for consistently meeting recruitment goals and conducting protocols at a high level of integrity.  As a result, we have been contracted to participate in more than a dozen clinical research trials. Over the past 30 years, we have participated in many multi-site trials aimed at investigating new behavioral and pharmacological treatments for substance use disorders.

The most recent trial we participated in was completed with nine other sites, including the University of Pennsylvania and Columbia University, as well as sites in San Diego, Denver, Baltimore, Albuquerque, Cincinnati, Houston and Salt Lake City. This study looked at a medication (nepicastat) for cocaine dependence with the aim of reducing the pleasurable effects of cocaine and facilitating the cessation of use.

CLARE|MATRIX is available to participate as a clinical site for future clinical trials involving medication and/or psychosocial treatment for substance use disorders. We are also interested in research involving the Matrix Model for Adults, Adolescents, and Criminal Justice, and may provide Matrix Model materials to researchers wishing to investigate psychosocial addiction treatments.
