Filter by:This is an exploratory mixed-methods research study that compares an efficacious behavioral HIV-prevention intervention (3MV) alone to the behavioral HIV-prevention intervention combined with a biomedical intervention (PrEP). After completing the 3MV behavioral intervention, participants will be randomly assigned to one of three study arms: 1) daily FTC/TDF as PrEP, 2) placebo pill control, or 3) "no pill" control. Behavioral and biomedical data will be collected at baseline and every 4 weeks thereafter for 24 weeks. Youth who decline to participate will be asked to complete a brief survey about their opinions on PrEP. Qualitative interviews will be completed with six study participants and the study coordinators at the end of the trial to explore further the issues of trial acceptability and feasibility. Finally, focus groups will be conducted to explore feasibility and acceptability issues with YMSM who meet all eligibility requirements of the study except for not being age 18 or older, but are at least 16 years of age.
This pilot study is a sub-study of ATN 067. ATN 067 utilizes a cross-sectional research design to recruit Latina and African American young women to undergo HIV screening. The primary goal of this proposed pilot study, ATN 084, is to explore the feasibility and acceptability of index female recruiters identifying and recruiting their past and present male sexual partners to undergo HIV screening and complete a one-time ACASI interview. In addition, the study will also include female friendship network members who were enrolled in ATN 067 and were diagnosed with HIV. These young women will also be asked to recruit their past and present male sex partners to undergo HIV screening.
Drug use (DU) is a major risk factor for HIV infection in many regions of the world. However, as highly active antiretroviral therapy (HAART) has been rolled out in South and South East Asia, less than 2% of individuals initiated on HAART were drug users (DUs) or former DUs, despite the fact that approximately 20% of HIV infections in the region are ascribed to DU. India is home to about 2.4 million HIV-infected individuals. Though, injection drug users contribute to only about 3% of all HIV infections in India; it is estimated that there are between 168,000 and 1.1 million DUs in India with HIV prevalence about 30%. Novel approaches are needed to engage disenfranchised populations in HIV care in lower and middle income countries, where the burden of HIV disease is growing. Incentive-based strategies (or contingency management) have been shown to be effective in reducing illicit drug use, smoking cessation, and weight loss. Short-term pilot studies have also shown that incentive-based strategies can improve electronically-monitored rates of adherence to HAART in the US, and a recent study in Africa showed that a small incentive approximately doubled the rate that individuals returned to learn the results of their HIV test. However, to date there is no experience with the use of incentive-based interventions to improve engagement into care and risk-reduction among out-of-care HIV-infected DUs in developing world settings. The investigators propose to conduct pilot randomized trial comparing a voucher incentive strategy to a control condition to improve engagement in HIV care and HIV treatment outcomes among out-of-care, treatment-eligible, HIV-infected DUs in Chennai, India. Subjects in the incentive arm will be eligible to earn incentive vouchers for 1) initiating HAART at a government-sanctioned HIV treatment clinic, 2) adherence to scheduled follow-up visits at the HIV clinic, and 3) achieving suppression of HIV RNA. Subjects will be enrolled from a mature research venue in Chennai, YR Gaitonde Centre for Substance Abuse-related Research (YRGCSAR), which focuses the epidemiology and natural history of HIV in DUs. Preliminary data from this pilot study will be used to inform the design of a phase-III study.
Although highly active antiretroviral therapy (HAART) decreases HIV-associated mortality, it does not to completely restore health. Patients doing well on otherwise effective HAART remain at risk for cancer, cardiovascular/liver disease, osteopenia, and other "non-AIDS-defining" events. While complete eradication may never be feasible, a "functional cure" in which patients are able to maintain undetectable viral loads indefinitely without therapy may be possible. The best evidence for this are the so-called "elite" controllers, whom we define as individuals who are HIV-seropositive, with plasma HIV RNA levels below the level of conventional detection without treatment. Controllers may be conceptualized as a naturally occurring model of a functional cure (or "HIV remission"), and are ideal patients in which to study HIV persistence and the possibility of eradication. We propose to conduct a pilot study to better characterize the reservoirs that lead to viral persistence in a group of well-characterized controllers. We propose two specific aims: 1) to characterize the dynamics of viral production in blood and gut-associated lymphoid tissue (GALT) in controllers; and 2) to prospectively treat 10 controllers with raltegravir, tenofovir/emtricitabine for 24 weeks and study the effects of HAART on viral dynamics and host inflammatory responses. Our primary hypotheses are: 1) viral replication is ongoing in untreated controllers, 2) HAART will reduce viral replication in blood and GALT and decrease immune activation, and 3) higher levels of immune activation are associated with greater measures of microbial translocation and distribution of virus to more differentiated T cell subsets.
This study will collect information on health status and risk behaviors, as well as basic demographic and biomedical information for a group of HIV positive adolescents receiving care at the ATN sites.
This is a two-phase study, consisting of the following plan: Phase I - This is a pre-test of the feasibility and acceptability of the beta version of a computer-delivered intervention, Motivational Enhancement System for Adherence (MESA), as well as the control intervention Motivational Enhancement System for Health (MESH) at three selected AMTUs. Following analysis of the responses in Phase I and further modification of the intervention, Phase II will be initiated. Phase II - This is a pilot, randomized, controlled trial (RCT) testing a two-session computer-delivered intervention, MESA, designed to increase motivation for adherence to Highly Active Antiretroviral Therapy (HAART) among youth newly recommended to begin medications, as well as an attention control, MESH, matched for dose and delivery format. Phase II is open to all 15 AMTUs.
The purpose of this study is to provide atazanavir or tenofovir-emtricitabine to HIV-infected subjects who have completed atazanavir or tenofovir-emtricitabine therapy on a previous BMS sponsored clinical trial
To assess 48-week treatment responses, tolerability, and steady-state minimum plasma concentrations of ritonavir-boosted lopinavir monotherapy for salvage therapy in HIV-1 infected patients who failed antiretroviral regimens containing NRTI and NNRTI.
Common treatments for tuberculosis (TB) can interfere with certain antiretroviral (ARV) medications used to treat HIV. People whose immune systems are weakened by HIV infection are susceptible to TB, so it is important to find treatments for both that can be given in combination. This study will test the safety of combining a new medication for TB with an already approved HIV medication in healthy adults.
The trial aim is to ascertain what, if anything, needs to be combined with a boosted protease inhibitor (bPI) backbone in second-line therapy in order to maximize the chance of a good clinical outcome following WHO-defined failure on a first-line nucleoside reverse transcriptase inhibitor (NRTI) and NNRTI-containing regimen with probable extensive NRTI and NNRTI resistance mutations.
