This study is designed to evaluate the safety of MVA85A in healthy volunteers in the UK who are infected with HIV. In phase I studies, a single vaccination with MVA85A, when administered at a dose of 5 x 10^7pfu intradermally, has been shown to be safe in both mycobacterially naïve individuals, those previously vaccinated with BCG and latently infected individuals. Additionally, 5 x 10^7 pfu MVA containing HIV antigens administered twice, 4 weeks apart, in HIV positive individuals, is safe. We will use 5 x 107 pfu MVA85A intradermally in this study. Subjects will be identified from HIV clinics in the Oxford Radcliffe Hospitals NHS Trust and also from Swindon and Marlborough NHS Trust and St. Mary's Hospital NHS Trust if our recruitment targets are not met.
This study will use focus groups and in-depth individual interviews to explore factors that influence the decision of Hispanics and African-Americans with HIV/AIDS to participate in a research study. HIV-positive Hispanic and African-American patients 18 years of age and older who are enrolled in an NIH HIV/AIDS protocol may be eligible for Part 1, Part 2, or both parts of this study, as follows: Part 1 - Focus group Focus group participants of from six to ten people are interviewed together during a one-time, 2-hour tape-recorded session to explore how they arrived at their decision to enroll in a research study. The group discussion is led by a moderator and a facilitator. Before the session begins, participants complete questionnaires that include information about their age, race, ethnicity, education and social support. Hispanic participants also complete a questionnaire about language preference. At the end of the focus group, participants are offered to be interviewed individually, as described below. Part 2 - In-depth interview An investigator conducts a one-on-one in-depth interview with the participant while a second person observes and tape records the interview. The interview may take from 1 1/2 to 2 hours to complete. Participants who were not in a focus group are asked to complete questionnaires as described in Part 1 above.
Connect to Protect (C2P): Partnerships for Youth Prevention Interventions is a multi-site, three-phase project developed by the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN). The overall goal of the project is to ultimately reduce HIV incidence and prevalence in youth 12-24 years old through a community mobilization intervention. This protocol (ATN 040) describes part one of Phase III. Part two of Phase III will be submitted as a separate protocol (ATN 041).
The purpose of this clinical research study is to assess the bioequivalence of atazanavir administered as a single 300 mg capsule relative to two atazanavir 150 mg capsules in healthy subjects.
Infection with either HIV or hepatitis C virus (HCV) affects immune system responses. The purpose of this study is to investigate the immune responses to two different vaccine formulations in HIV-infected, HCV-infected, and HCV/HIV- coinfected individuals.
This study will evaluate the safety, pharmacokinetics and efficacy of the CCR5 antagonist INCB009471 in HIV-1 infected patients who are antiretroviral therapy naïve, or who are not currently on a HAART regimen and have not received any antiretroviral agents for 3 months prior to the Screening visit. Subjects will receive study medication (INCB009471) admnistered orally or placebo once daily with food for 14 days. Clinical safety laboratories, 12-lead electrocardiograms, physical examinations and virologic assessments, including viral load, viral tropism and CD4+ cell count determinations will be performed at the Screening visit and at regularly scheduled visits throughout the study. A blood sample will also be obtained and stored to potentially determine the genotype of the CCR5 receptor. The primary objectives are: 1. Assess the safety and tolerability of 3 doses of INCB009471 or placebo when administered orally, once daily, as monotherapy for 14 days; 2. Determine the pharmacokinetics of 3 doses of INCB009471 or placebo when administered orally, once daily, as monotherapy for 14 days; 3. Evaluate the anti-retroviral activity of 3 doses of INCB009471 or placebo when administered orally, once daily, as monotherapy for 14 days
HBe seroconversion is an important goal for anti-HBV treatment, since it is associated with a non progressive liver infection and a better clinical outcome. However, the rate of HBe seroconversion is low in HIV-HBV co-infected patients, mostly treated by tenofovir and emtricitabine. This study will evaluate the efficacy and the safety of a one-year Peg-interferon alpha 2a additional treatment in patients already treated by tenofovir and emtricitabine without reaching HBe seroconversion.
The purpose of this study is to determine whether a six-session, small group behavioral intervention based on "peer-volunteer activism" is effective in (1) decreasing distributive sharing of syringes and other injection paraphernalia and (2) increasing utilization of HCV-related healthcare services among HCV-infected injection drug users
The purpose of this study is to determine whether community-based peer education and condom distribution combined with improved treatment of sexually transmitted infections are effective in reducing the spread of HIV infection in a sub-Saharan African population
