Filter by:The HIV Vaccine Trials Network (HVTN) is doing a study to test 2 experimental HIV vaccines in combination with 2 licensed vaccines for tetanus and hepatitis B. HIV is the virus that causes AIDS. Tetanus is an infection that causes muscular spasms. Hepatitis B is a virus that can cause liver failure. About 100 people will take part in this study at multiple sites. The US National Institutes of Health (NIH) is paying for the study. We are doing this study to answer several questions. - Are the HIV study vaccines safe to give to people? - Are people able to take the HIV study vaccines without becoming too uncomfortable? - How do people's immune systems respond to the HIV study vaccines? (Your immune system protects you from disease.) - Can people's immune responses to a tetanus or hepatitis B vaccines help us understand how their immune systems might respond to the HIV study vaccines? - Is there a common immune response to licensed vaccines like the tetanus and hepatitis B vaccines?
HIV infection is associated with premature aging of the immune system. It is believe that the persistent inflammation that accompanies HIV infection is a major contributor to premature immune aging. Fish oil has well-documented anti-inflammatory properties. In this randomized, clinical trial, we're testing whether a 12-week course of fish oil supplementation will reverse premature aging in HIV-infected older adults.
This study will allow to assess liver related injuries in HIV patients.
This study seeks to determine the public health impact of providing rapid HIV test kits to men who have sex with men (MSM) so they may test themselves at their convenience. The study will determine if men who receive the rapid HIV test kits report HIV testing at least three times per year. This study will be conducted in four consecutive parts. The first three parts are formative in nature to guide the development and implementation of Part 4 of the study. The research study will use two different types of rapid HIV tests. The OraQuick® In-Home HIV Test for oral fluid (FDA approved for home use) and Sure Check® HIV 1/2 Assay, currently FDA-approved for professional use and distributed in the U.S. as Clearview® Complete HIV-1/2 Rapid Test. An Investigational Device Exemption will be obtained from the FDA to allow the contractor to supply the Sure Check® HIV 1/2 Assay to study participants since it is not approved for home use.
In sub-Saharan Africa (SSA), more than 300,000 babies with HIV die each year. HIV-infected children develop AIDS and die faster in SSA than those in developed countries. Bacille Calmette-Guerin (BCG) vaccine is given to infants at birth in SSA to protect them from severe forms of TB. BCG is known to cause immune cells to be active and replicate faster. The immune system of neonates also responds differently to BCG that to other vaccines and infections. We hypothesize that the routine immunization of neonates with BCG contributes to generalized immune activation in HIV-exposed infants resulting in skewed immune responses to vaccines and infections and increased rates of disease progression in those infants that become HIV-infected. However, delaying BCG until HIV testing is completed would result in operational difficulties, and may not induce the appropriate immune response. Delayed BCG would also render many HIV-exposed uninfected infants at high risk for disseminated TB. We plan to assess immune cells in infants to determine the impact of the timing of BCG vaccination on immune responses to tuberculosis (TB) and other vaccines. We will also compare the immune activation and disease progression of those infants that become HIV-infected in the BCG or control arms. Our results will provide key insights into the effect of BCG vaccination on immune responses to HIV as well as inform the optimal timing of BCG vaccination for HIV-exposed infants.
The objectives of this Phase I/II trial is to evaluate the safety, tolerability and immunogenicity of THV01 compared to placebo in HIV-1 infected patients on HAART (highly active antiretroviral therapies). THV01 is composed of two vaccines that derived from the HIV (human immunodeficiency virus): lentiviral vectors. They are non-replicative and not infectious. They will be injected intramuscularly, eight weeks apart. Three doses will be assessed and compared to placebo. Eligible patients must have an undetectable viral load and must be treated by HAART for more than 12 months. They will be randomly allocated to one of the study group and will receive the experimental drugs at one of the three doses or a matching placebo. Their anti-HIV treatment will be alleviated around each experimental drugs' administration to enable THV01 efficacy. HAART will be resumed one week after the second injection. 15 weeks after resumption, HAART will be interrupted. Patients will then be monitored every 2 weeks for CD4+ T cell counts and viral load as well as for thorough assessment of the elicited immune response. Stringent anti-HIV treatments resumption criteria have been implemented, based on the CD4+ T cell counts and the viral load. 38 patients were enrolled in THV01-11-01 study and received the 2 injections. A long-term follow-up of all enrolled patients will be performed for 5 years post-prime administration. This will provide additional data on the safety and the potential long-term risks/benefits associated with THV01. The final study report will be written after the last patient last visit in the long-term follow-up.
The development of a safe and effective HIV-1 vaccine strategy would probably be the best solution for the ultimate control of the worldwide AIDS pandemic. Heterologous prime-boost immunisations are today considered promising HIV prophylactic vaccine strategies. It is thus relevant to pursue the development of different candidate vaccines in prime-boost vaccine strategies to identify the most promising prime-boost combinations and to integrate scientific inquiry into trial protocols from the beginning to maximize learning opportunities.
This is an open-label, single group study to determine the pharmacokinetic profile of atazanavir 300 mg daily boosted with ritonavir 100mg daily in HIV-infected patients over a period of 9 days. Ritonavir and atazanavir are protease inhibitors used to treat HIV. However, ritonavir, when used at low doses (up to 100mg) does not have HIV activity, but will enhance (boost) the blood concentrations of other drugs like atazanavir. Recently, a study showed that taking 50mg of ritonavir administered in an oral solution led to similar blood concentrations of atazanavir than when given with 100mg of ritonavir. Potential benefits associated with a lower dose of ritonavir may include a reduction of side effects such as upset stomach and an improvement in cholesterol level. This study will look at the amount of atazanavir into your blood when given with ritonavir in a tablet formulation at 50mg or 100mg with standard atazanavir dose (300mg).
This study will estimate the rates of asymptomatic Chlamydia and/or Gonorrhea in the oropharynx, rectum and urethra (urine) of HIV infected men who have sex with men at a specialty care center and compare it to the rates in Douglas County, using nucleic acid amplification tests.
The Centre for Infectious Disease Research in Zambia (CIDRZ) and researchers from the University of North Carolina at Chapel Hill (UNC) have partnered to pilot an peer-referral incentive program to increase voluntary medical male circumcision (VMMC) uptake in Zambia. The program allows each man coming for circumcision to refer up to 5 uncircumcised men in their social network for VMMC services and receive a monetary reward for each successful referral. The peer-referral program offers several advantages over traditional demand-creation approaches that rely on employing mobilizers or community health workers (CHWs). The amount of the monetary incentive will be analogous to the amount of incentive that CHWs might receive for comparable effort, making the program suitable for large-scale expansion. The effect of the peer-referral program on uptake of VMMC services will be evaluated using a rigorous methodology proposed by UNC researchers.
