Filter by: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 study is a phase I/II, double-blind, placebo-controlled, randomized cross-over clinical trial of tocilizumab (TCZ) or placebo in HIV-infected subjects receiving antiretroviral therapy with suppressed viral replication and CD4+ T cell count ≥350 and ≤1,000 cells/mm3)
Substance use, particularly the compulsive behaviors associated with addiction, lead to unhealthy behaviors including non-adherence to antiretroviral therapy (ART) and treatment failure. High on the list of disorders leading to non-adherence is heroin addiction as a wide range of impulsive, high-risk behaviors accompanies it. The science of adherence would be improved by developing new methods to prevent relapse to heroin addiction, especially methods that can be used in settings that are not limited by the aims to test such a method using an implantable naltrexone formulation (IN) that is approved in Russia and blocks opioid effects for 3 months. The efficacy of the IN should be better than oral naltrexone (ON) because it does not depend on daily behavior to take a tablet and maintains a constant plasma level for months, which should result in sustained blockade, less relapse, and better ART adherence and treatment response.
The Pediatric Enhanced Surveillance Study is a three part study of HIV-infected infants and children in South Africa to examine, clinical, immunologic, virologic, metabolic, psychosocial and behavioral outcomes. This study has two parts: (1) comprehensive de-identified records review of all HIV-infected children enrolled in at the pediatric Wellness and ART clinics at the five study sites; and (2) a prospective cohort surveillance study with active consented enrollment with 12-24 months of follow-up. As part of the prospective cohort, the study will aim to collect outcomes on children lost to follow-up, including causes of death through review of death certificates in the clinical chart and through verbal autopsy reports. The study will provide insights into overall outcomes for the larger pediatric patient populations in the province and South Africa. This work is designed in collaboration with the provincial health authorities of the Eastern Cape Department of Health (EC), The International Center for acquired immune deficiency syndrome (AIDS) Care and Treatment Programs (ICAP) South Africa and Center of Disease Control (CDC)-South Africa in support of the South African National ART Program for Children and aims to collect and analyze accurate, relevant and useful information that will be available on children seen at facilities. For the prospective cohort study, we will aim to enroll 400 children newly initiated on ART at 5 health facilities in the Eastern Cape of South Africa who will be actively followed for up to 24 months.
The purpose of this study is to: - find out the intensity and duration of the immune response after multiple injections of the investigational study product AGS-004 made from one's own dendritic cells and one's own strain of HIV; - understand the changes in the body's HIV DNA , and HIV-1 RNA in peripheral and resting CD4+ cells prior to and following administration of AGS- 004. - find out if low levels of HIV virus that are not detectable by standard HIV RNA assays will decrease following the administration of AGS-004. - find out if it is safe to give individuals with HIV multiple injections of AGS-004 made from the person's own dendritic cells and their own strain of HIV. - find out if administration of AGS-004 decreases the amount of latent HIV infection in resting CD4 cells
The main purpose of this clinical trial is to generate additional safety data in a highly immunocompromised population. HIV-infected persons are considered excellent candidates to represent the highly immunocompromised population for enrolment in this trial. Additionally, the immune system's response (protection against smallpox as measured by the amount of antibodies produced) following injections of MVA-BN® smallpox vaccine will be evaluated. All participants in this trial will be randomly and evenly assigned to one of three groups to receive two, three or four injections. Group 1 will receive the standard regime consisting of one dose at each vaccination time point, Group 2 will receive two doses at each vaccination time point and Group 3 will receive a booster vaccination 12 weeks after the standard vaccination schedule with MVA-BN® smallpox vaccine. Participation in the trial is scheduled to last up to 75 weeks.
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 study identifies social and behavioral factors likely to influence PrEP acceptability and adherence among men who have sex with men (MSM), and collaborates with a community health center to evaluate a two-stage intervention to improve PrEP decision-making, as well as persistence and adherence for those who chose to take PrEP.
This project aims to assess the effect of group peer support to children with HIV in relation to adherence, virological treatment failure as well as physical development. A randomised controlled trial (RCT) will be used where HIV+ children on antiretroviral treatment (ARV) and their caretakers are randomized into either enhanced treatment support (ETS) through peer supporters or the conventional treatment (CT) according to the guidelines of The National AIDS Control Program. The treatment strategies will be assessed and compared in relation to virological treatment failure as primary endpoint, immunological and clinical (AIDS events and mortality) as secondary endpoints as well as treatment adherence and physical development. The results from this project will lead to an increased knowledge in relation to the impact of enhanced treatment support on adherence, virological suppression and resistance development for children with HIV and have an impact on HIV treatment policies and guidelines for Pediatric HIV in low-income settings globally.
