Filter by:The purpose of this study is to evaluate the relationship between anti-retroviral therapy (ART) adherence with levels of human immunodeficiency virus (HIV) reservoir and residual viremia in suppressed, HIV-infected individuals on chronic ART.
Scaling up integrated, cost-efficient HIV services for people who inject drugs (PWID) in Needle Syringe Programs (NSPs) is urgently needed in Kazakhstan, where only one-third of the estimated 19,000 HIV-positive PWID are ever linked to HIV care and only 10% initiate ART with 4% achieving viral suppression. The study's aim is to evaluate the implementation, effectiveness, and sustainability of an integrated HIV service model in 24 NSPs located in 3 Kazakhstani city areas. This model will employ highly effective strategies that will include peer-driven recruitment of PWID in NSPs using social network strategies (SNS), integrating rapid HIV testing in NSPs with HIV Care Clinic nurses, and linking HIV positive PWID in NSPs to HIV care using the ARTAS (Anti-Retroviral Treatment and Access to Services) case management model. Findings will have important public health implications for improving HIV service delivery for PWID in the Central Asian region and other countries with injection driven epidemics.
GSK2838232 is a Human Immunodeficiency Virus (HIV) maturation inhibitor being developed for the treatment of HIV in combination with other antiretroviral therapy (ART). The primary objectives of this study are to investigate the safety, tolerability, and pharmacokinetics (PK) of single and repeat doses of GSK2838232. This study will be a double-blind, placebo-controlled, single and repeat dose escalation study. This study will be conducted in two Parts: single escalating doses (Part 1A and 1B), and repeated escalating once daily (QD) doses for 11 days (Part 2) of GSK2838232 co-dosed with RTV. During Part 1A, single doses of GSK2838232 (as of active pharmaceutical ingredient-powder in bottle [API PiB]) 50 milligrams (mg), 100mg and 200mg will be administered with RTV. Part 1B will evaluate the relative bioavailability of single doses of crystalline active pharmaceutical ingredient (API) Immediate Release Tablet (IR) tablets versus API PiB as reference, administered with RTV. In Part 2, multiple doses of GSK2838232 will be co-administered with RTV 100mg QD for 11 days as sequential dose cohorts. Maximum duration of study participation will be approximately 10 weeks.
Background: In most people infected with human immunodeficiency virus (HIV), their immune system cannot control HIV infection. They need drugs called combination antiretroviral therapy (cART) to control the HIV. When people stop cART treatment, their immune system cannot control the infection again. They can also become resistant to cART and have lasting side effects. Researchers want to test if the drug vedolizumab is effective at controlling HIV infection without the need for cART. Objective: To test if vedolizumab is safe and can control the amount of HIV in the blood when cART is not taken. Eligibility: People ages 18-65 who have HIV and are being treated with cART Design: Participants will be screened with: Physical exam Medical history Electrocardiogram: Soft, sticky patches on the chest, arms, and legs measure heart activity. Blood and urine tests Participants will have a baseline visit. This will be 2-5 hours each day for 1-2 days. It will include repeats of the screening tests and: Leukapheresis: Blood is removed through a needle in the arm. A machine separates the white blood cells from the blood. The rest of the blood is returned to the participant. Neurologic exam: The nerves and reflexes are tested. First vedolizumab infusion through an arm vein Participants will have visits every 4 weeks for 30 weeks. These will include: Vedolizumab infusions Repeats of baseline tests Participants will have more visits for blood draws. Participants will keep taking cART until after the week 22 infusion. After discontinuing cART at study week 22, participants will be seen every two weeks to monitor the CD4 count and the level of HIV in the blood. Some of these visits will occur in between infusion visits and will only take about 1 hour to complete. cART will be restarted if a participant's HIV levels go up to high, or if their CD4 cell counts decreases by too much. For the follow-up phase, participants will have visits every 4 weeks for 24 weeks. These will include blood tests and a physical exam. ...
To provide access to maraviroc to patients who have limited or no therapeutic treatment options and to collect more safety data in a broader patient population.
This study aimed to evaluate the safety, tolerability, and pharmacokinetics of maraviroc in infants at risk for mother-to-child HIV transmission, and to determine an appropriate dose of maraviroc during the first six weeks of life.
The purpose of this protocol is to determine user preferences for antiretroviral therapy (ART) for HIV-1 infected partners and pre-exposure prophylaxis (PrEP) HIV-1 un-infected partners and to optimize targeted delivery and sustained use of these interventions.
single-center, national clinical trial, phase I, randomized (1: 1: 1: 1), prospective, placebo-controlled, partially masked, parallel group. Patients will be assigned to one of the following four arms: 3 immunizations of dendritic cells / 3 immunizations of dendritic cells with pegylated interferon + / 3 immunizations of placebo / 3 immunizations of placebo with pegylated interferon.
The aim of this study was to assess tolerability and safety of three different formulations of an anti-HIV immunotherapy based on autologous dendritic cells (DCs) pulsed with HIV chemically inactivated with Aldrithiol™-2 (AT-2). Patients were chronically infected with HIV, naïve for antiretroviral drugs. A possible immunological and virological favorable impact was also assessed.
This is a randomized, double-blind placebo-controlled dose-escalation clinical trial to evaluate the safety and the immunogenicity of Adenoviral vector 5 HIV-1 vaccines in subjects receiving stable highly active antiretroviral therapy(HAART) .
