Perrine Roux, Pharm.D., Ph.D., French National Institute of Health and Medical Research (Inserm), has been selected as a NIDA INVEST Drug Abuse Research Fellow. She will work with Sandra D. Comer, Ph.D., Columbia University, to better define the concept of nonadherence to opioid maintenance treatment with buprenorphine/naloxone and to validate a tool to measure nonadherence using a self-administered questionnaire. The researchers predict that identification of factors associated with nonadherence will provide important information on how to improve clinical management and outcomes in patients abusing heroin or prescription opioids, with or without chronic pain symptoms. At Inserm, Dr. Roux has participated in a longitudinal study of drug treatment for marginalized populations, a national trial of hepatitis C risk reduction interventions for prisoners, and a trial of methadone in primary care for hepatitis C prevention.
