Filter by:The purpose of this study is to evaluate the safety and immunogenicity of the IHV01 protein vaccine primed and co-administered with HIV DNA CON-S env vaccine in healthy, HIV-1-uninfected adults.
This study evaluates the efficacy, safety and tolerability of switching from the older, established single tablet regimen of ATRIPLA® (EFV/FTC/TDF) to a new single tablet regimen of BIKTARVY® (BIC/FTC/TAF), in HIV-1 infected adult subjects who are virologically suppressed (HIV-1 RNA<50 copies/mL).
The investigators propose a pilot study using (1) MRI to assess coronary artery endothelial function, (2) brachial ultrasound to assess systemic endothelial function, (3) serum markers of inflammation and of endothelial cell function and (4) echocardiographic measures of left ventricular diastolic and systolic properties, before and following initiation of PCSK9 antibody in HIV positive subjects.
This is a phase 2, open-label efficacy study of VGX-3100 administered by intramuscular (IM) injection followed by electroporation (EP) in adult men and women who are human immunodeficiency virus (HIV) negative with histologically confirmed anal or anal/peri-anal high-grade squamous intraepithelial lesion (HSIL) associated with human papilloma virus (HPV)-16 and/or HPV-18. Approximately 24 participants will receive at least 3 doses of VGX-3100.
The purpose of this study was to determine the dosage for oral cabotegravir (CAB) and long-acting cabotegravir (CAB LA) and long-acting rilpiverine (RPV LA) LA and evaluate the safety, acceptability, tolerability, and pharmacokinetics (PK) of oral CAB,CAB LA, and RPV LA in virologically suppressed HIV-infected children and adolescents.
The XN-20, is a full blood count (FBC) analyser with an extended differential counting and flagging System. The XN-Series' individual channels allow real-time reflex analysis, and uses a two stage process to classify the white blood count (WBC) sub-populations and detect the presence of abnormal reactive and malignant cells. In regards to lymphocytes in the peripheral blood, the machine has the capacity to distinguish activated from non-activated T-cell subsets using a very small volume of EDTA sample (88uL) (including remnant sample from a standard full blood count) with results available in 1.5 minutes. It is a fully automated process and can be considered as an alternative rapid flow cytometry method. Objective of the SASA study: to investigate the signal pattern of white blood cells assessed using the XN-20 full blood count platform in patients with untreated viral infections i.e. HIV, HCV and HBV. The data from the analysis will be reviewed in conjunction with patient's demographic and clinical disease characteristics with the aim of detecting characteristic cell populations that can be used in the development of system flags for future studies.
This study will implement an intervention in a two-year randomized controlled trial (RCT) to establish efficacy on viral suppression as a biological endpoint, compare the effectiveness of two different modes of implementation (including one entirely based on readily available clinic data), and investigate cost-effectiveness. Participants in the first intervention group (T1, n=110) will be eligible for small lottery prizes based on timely clinic visits, and qualify for an annual lottery conditional if demonstrating viral suppression; those in the second group (T2, n=110) will draw prizes conditional on electronically measured adherence at each clinic visit, and also participate in an annual lottery that is conditional on high adherence throughout the year. The control group (n=110) will receive the usual standard of care. Assessments will be conducted at baseline and then every six months. Primary outcomes are undetectable viral load and electronically measured adherence.
The POWER Cohort study is a PrEP implementation project to demonstrate Pre-exposure prophylaxis (PrEP) delivery for young women in Cape Town and Johannesburg, South Africa and Kisumu, Kenya.
Older adults with human immunodeficiency virus (HIV) and a long history of antiretroviral therapy have more mitochondrial dysfunction- the cells that help them make energy. This dysfunction in mitochondria may lead to symptoms of muscle fatigue, physical function impairment, and impaired exercise tolerance compared to HIV-uninfected controls of a similar age and body mass index (BMI). Furthermore, the investigators hypothesize that the older antiretroviral therapy (ART) of tenofovir disoproxil fumarate (TDF) is associated with greater impairment in mitochondrial function than the newer agent, tenofovir alafenamide (TAF).
Background: Weight gain can lead to obesity and diabetes even in people living with human immunodeficiency virus (HIV). Researchers want to see if the technique intermittent calorie restriction can help overweight people with HIV as an alternative to traditional diets. Objective: To see if intermittent calorie restriction leads to weight loss and improved blood sugar in obese people with HIV. Eligibility: Adults ages 18-65 with HIV who are obese and do not have diabetes Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Before starting treatment, participants will: - Have a nutritional consultation - Get a pedometer to record daily steps - Test a restricted diet for 1 day - Have a body x-ray At the baseline visit, participants will have: - Blood drawn after they drink a sugar drink - Questions about their health and eating - A nutritional consultation - Resting energy expenditure measured. Participants will fast overnight. Then they will lie down while a plastic bubble goes over the head and a plastic sheet covers the upper body. Oxygen flows into the bubble. - Liver stiffness test. A wand on the stomach releases sound waves like an ultrasound. For 12 weeks, some participants will be on a standard diet. Others will restrict how much food they eat 2 days a week. On those days they will eat about 25% of their recommended calories. Participants will keep a diary of their diet and steps. Participants will have 4 visits during the 12-week diet and 1 visit 12 weeks after the diet ends. They will repeat previous tests.
