NCT ID: NCT02225184 Completed - Clinical trials for Drug Abuse/Dependence

Impact of Delta Opioid Receptor Gene (OPRD1) Variations on Treatment Outcome in African Americans

Start date: August 23, 2014
Phase:
Study type: Observational

Background: - Differences in peoples genes can make them respond to drugs in different ways. Methadone and buprenorphine are two drugs used to treat drug addiction. A study showed that African Americans with a certain genetic marker did better using one kind of drug treatment over the other. Researchers want to see if they can repeat these findings. They also want to study other things that affect how well people do in treatment. Objective: - To see if certain genetic markers and other facts about a person s life can predict how well they do in treatment for addiction to opioids and cocaine. Eligibility: - African American adults age 18 and over. They must be former or current participants in an Archway Treatment Clinic study. They must have been on a stable dose of either study drug for at least 12 weeks. They also must have given urine samples regularly for at least 10 weeks. Design: - Participants will come to the clinic for 1 visit lasting about 2 hours. - Participants will give 1 teaspoon of blood for genetic testing. They will be asked if their sample can be used in future studies. - If researchers cannot get enough blood, they will do a cheek swab. This will collect skin cells for genetic testing. - Participants will fill out 3 questionnaires. - Results of genetic testing and answers to questionnaires will be kept private.

NCT ID: NCT01678833 Completed - Clinical trials for Drug Abuse/Dependence

Understanding Drug Abuse Treatment Outcomes

Start date: July 19, 2012
Phase:
Study type: Observational

Background: Although some treatments for substance abuse are considered effective for some people who are drug dependent, many others do not benefit as much over time. Researchers are working to find out what characteristics predict treatment response. They also want to determine how to design treatments that are more effective for a greater number of substance abusers. This pilot study involves providing drug addicts with cognitive behavioral therapy (CBT), a treatment considered to be one of the most effective in reducing substance-abuse, to identify ways in which the brain works that may predict and explain treatment effects. A comparison group will be included that receives only standard psychotherapy or talk therapy. This approach will enable researchers to determine what factors might be interfering with favorable treatment outcomes and how to refine or develop new treatments that work well for more people. Objectives: - To identify individual characteristics which predict and explain the effects of CBT in people with opiate dependence. Eligibility: - Males between 18 and 60 years of age who are dependent on opioids (such as heroin). - Participants must be willing to take buprenorphine and receive substance abuse counseling. Design: - Participants will be screened with a physical exam and medical history. - Researchers will ask questions about participants ability to cope in certain situations, along with questions about drug use and lifestyle issues. These questions will be asked twice, before and after completing treatment. - Participants will be placed into one of two groups. One group will have CBT twice a week for 8 weeks. The other group will have standard counseling twice per week. Both groups will take buprenorphine as part of the drug abuse treatment. - Participants will have other tests during this study. They will have imaging studies to look at brain function. These studies will test thinking and decision making.

NCT ID: NCT01571752 Completed - Stigma Clinical Trials

Health Outcomes by Neighborhood - Baltimore

Start date: July 17, 2012
Phase:
Study type: Observational

Background: - Researchers have been studying patterns of mood and drug use in specific neighborhoods. This study will look at environmental factors that may affect drug use, addiction, and treatment seeking in Baltimore neighborhoods. The results could inform prevention efforts, enhance treatment interventions, and improve substance use outcomes. Objectives: - To better understand why some people start to use drugs, why some people who use drugs become addicted, and why some people who become addicted enter treatment. Eligibility: - Individuals at least 18 years of age who are living in the neighborhoods participating in the study. Design: - Participants will be screened with a physical exam and medical history. They will be separated into one of four groups: (1) people who do not use drugs, (2) people who have used drugs in the past, (3) people who are using drugs and want treatment, and (4) people who are using drugs and do not want treatment. - This study will include two outpatient visits about 12 months apart. Each visit will last about 5 hours. Each study visit may be done in 1 day or in 2 days. - At each study visit, participants will provide blood, breath, urine, and saliva samples. They will also have a heart function test and body measurements. They will complete questionnaires about personal and family history. - There will be monthly follow-up phone calls between the two visits.
