HIV Status clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

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.
