Active clinical trials for "HIV Infections"

This study aims to test if small incentives promote linkage to care and 6-month viral suppression among individuals recently tested for HIV at selected sites within Johannesburg, South Africa. Individuals who obtain a reactive HIV test result will be randomized to receive either the standard of care (SOC) for linkage to care or to receive financial incentives for confirmatory testing, linkage to care and viral suppression.

This is a randomized controlled trial to test a combination behavioral and biomedical interventions to improve the HIV prevention and care cascades in a population of mobile men in a high priority setting (fishermen in Kenya). The intervention strategy is to recruit and train highly socially-connected men to distribute HIV self-tests and provide linkage support to men in their close social networks. The study will determine whether this social network-based approach along with small financial incentives in the form of transport vouchers can increase men's self-testing, linkage to and uptake of ART and PrEP after self-testing, virologic suppression at 6 months (for those initiating ART) and PrEP adherence (for those initiating PrEP) at 6 months. The study includes a longitudinal qualitative and mixed methods (quantitative and qualitative assessments) to identify the pathways of intervention action, and understand how the social network-based approach with support for linkage affects testing and ART and PrEP uptake and retention in men.

Tenofovir 1% gel is an investigational vaginal microbicide intended to reduce the risk of transmission of HIV. Pregnant women and mothers who have recently given birth often maintain sexual activity, and research has shown that they may be at greater risk of HIV infection during pregnancy. Microbicides may be able to prevent HIV infection during pregnancy, which would also prevent fetal exposure to HIV. This study will test the safety of using tenofovir 1% gel in healthy, pregnant women and healthy, breastfeeding women.

This is a randomized, open label, phase II trial to evaluate the safety and immunogenicity of two different schedules of vaccination against influenza A H1N1 in HIV-infected individuals, in which each of the randomized groups will be compared with HIV-negative volunteers vaccinated with the regimen indicated by the Brazilian National Immunization Program. Will be included in the study HIV-infected patients, stratified by CD4 count (< 200 cells/mm3 or > 200 cells/mm3) at the time of screening for the study, not receiving antiretroviral therapy treatment or receiving stable treatment for at least 8 weeks, with no plans to change over the next 6 months, eligible to receive vaccine against influenza A H1N1. The control group will be formed by HIV-negative individuals, confirmed by serology performed at screening, eligible to receive vaccine against influenza A H1N1. Patients infected with HIV will receive one of two possible vaccination regimens: 1) 3.75 µg in two applications 21 days apart, 2) 7.5 µg in two applications 21 days apart. The volunteers in the control group will receive a single application of 3.75 µg dose of the vaccine. The study's hypotheses are: 1) The vaccine against the H1N1 virus promotes antibody titers above the level specified for protection (seroconversion), being as safe and well tolerated in patients HIV-1 infected as in non HIV-infected volunteers; 2) The proportion of seroconversion for H1N1 virus vaccine at a dose of 3.75 µg in HIV-1-infected patients is similar to the proportion of seroconversion induced by the same vaccine at a dose of 7.5 µg; 3)The proportion of seroconversion with one dose of the vaccine against H1N1 virus is similar to the proportion after the second dose.

The purpose of this study is to determine whether the availability of home self-testing for HIV will increase HIV testing frequency among men who have sex with men without negatively impacting their risk for HIV acquisition.

As a measure of secondary prophylaxis, and with the final objective of avoiding the infection, it has been suggested to use antiretroviral therapy. This is known as post-exposure prophylaxis (PEP). Although there are different recommendations, almost every guideline recommend using 3 drugs as PEP both in USA and Europe. Toxicity is one of the main limitations of PEP. Side effects during PEP are very usual, are attributed mainly to PI and are the main reasons for poor adherence or lost of follow-up. A current standard regimen is AZT+3TC (Combivir®) or tenofovir+emtricitabine (Truvada®) plus the PI lopinavir/r. Toxicity associated with this regimens are high (31-85% of cases), with a 10-35% interruption of PEP Maraviroc, a CCR5 receptor antagonist, very well tolerated, coul be an adequate drug for PEP.

This trial is evaluating a public health intervention strategy trial which aims to reduce the incidence of HIV at a population-level. The proposed strategy is a two steps process: Extensive HIV counselling and testing, and comprehensive prevention programme among a target population Immediate ART initiation after HIV diagnosis, irrespective of CD4 count criteria. The underlaying trial hypothesis is that HIV testing followed by immediate ART initiation of all HIV-infected individuals will prevent onward transmission and reduce HIV incidence in the population. This is a cluster randomised controlled trial with a total of 22 communities used as the units for randomisation. Enrolment of a population of 22 000 individuals among which 4 400 are expected to be HIV-Infected.

The purpose of this project is to compare the effect of a family-based HIV prevention program to the effect of an adolescent-only health promotion program on adolescent HIV risk and marijuana use among adolescents enrolled in the Juvenile Drug Court (JDC) of the Rhode Island Family Court.

The purpose of this study is to assess the safety and tolerability of intravaginal administration of P2G12. 11 subjects will receive P2G12/placebo. Three subjects in Group 1 will receive up to 7mg of P2G12, or placebo. Three subjects in Group 2 will receive up to 14mg of P2G12, or placebo and five subjects in Group 3 will receive up to 28mg of P2G12, or placebo. A safety review will take place before subjects in Groups 2 and 3 receive study drug to determine if it is safe to proceed to the next dose of P2G12. Vaginal and cervical inspections will be performed to determine what effect, if any, the study drug has had on the site of administration. Adverse event data will be collected throughout the trial.

This study involves conducting formative research to develop a culturally appropriate secondary prevention intervention for HIV-positive Black young men who have sex with men (B-YMSM). The intervention draws upon the principles of Critical Consciousness Theory (CCT). The formative research includes reviewing data and findings from relevant ATN protocols (i.e., 070, 068, and 073) and existing health promotion interventions targeting young men of color (i.e., the Young Warriors program, Hermanos de Luna y Sol [HLS]) and conducting focus groups with up to 32 HIV- positive B-YMSM.
