Filter by:This study will enrol African, Caribbean and Black (ACB) women who are known to have a more diverse vaginal microbiome, higher rates of bacterial vaginosis with lower numbers of protective lactobacilli, and are at increased risk for HIV. The investigators will evaluate the safety, feasibility, effect on the vaginal bacterial microbiome and changes in local immune and inflammatory responses with the administration of vaginal estrogen alone, vaginal estrogen in combination with oral or vaginally administered probiotics, or vaginal probiotics alone.
The ARBRE Study is an observational prospective trial aimed at investigating the impact of the therapy initiation with INTIs on brain outcomes according to the time of therapy initiation. Three study arms are considered: 1) Early treated HIV-1 infected patients (<3 months since estimated date of infection), 2) Regularly treated HIV-1 infected patients (>6 months since estimated date of infection), 3) Matched seronegative control group. Study assessments will be performed at baseline, 1 month and 12 months. Study assessments will comprise comprehensive evaluation of brain outcomes. They will include cognitive functioning, neuroimaging parameters, and functional outcomes.
This trial is a prospective, multi-center, randomized comparison study of 2 Pre-Exposure Prophylaxis (PrEP) pharmacokinetic (PK) dosing regimens from 1st trimester through 12 weeks following delivery (postpartum) to achieve study objectives which include PK, safety monitoring for maternal and fetal/infant safety signals, and adherence.
The most commonly used illicit stimulant in HIV-infected individuals is methamphetamine (MA). Prior studies demonstrate strong evidence that MA promotes increased HIV transcription as well as immune dysregulation. A challenge in achieving worldwide HIV eradication is targeting specific marginalized populations who are most likely to benefit from an HIV cure but possess poorer immune responses. For this study, HIV+ infected ART-suppressed individuals with no prior history of MA use disorder will be administered oral methamphetamine (the maximum FDA approved daily dose for the treatment of childhood obesity) to determine the effects of short-term MA exposure on residual virus production, gene expression, and inflammation. Measures of MA exposure in urine and serum will then be associated with residual virus production, gene expression, cell surface immune marker protein expression, and systemic markers of inflammation. The clinical trial data will generate advanced gene expression and immunologic data to identify potential novel targets for reversing HIV latency, reducing inflammation, and personalizing future therapies in HIV+ individuals who use MA.
EVAI2020_01 is a single blinded two part experimental medicine study to determine the extent to which different prime-boost combinations of model immunogens based on HIV-1 envelope proteins (ConM and ConS), influence the breadth of viruses neutralised by induced antibodies and the associated diversity of B and T cell responses. Our research will investigate the effect of a second immunisation challenge with a combination of three model mosaic envelope proteins designed to increase the breadth of induced antibody neutralisation. The primary outcome will be measurement of specific viral neutralisation activity of serum antibodies. Exploratory outcomes will include characterisation of blood B and T cell responses to these model immunogens.
This is an open-label, parallel-group, nonrandomized, multi-centre, phase-IV, single dose trial in 8 HIV-seronegative subjects with severe hepatic impairment and 8 matched controls to assess the pharmacokinetics of a single dose of 50mg of dolutegravir in subjects with severe hepatic impairment.
Adult participants (18-64 years old) with HIV-1 Infection on ART with a CD4 T cell count ≥ 350 cells/mm3 and viral suppression for ≥ 24 months will be enrolled on this study. Participants will receive two series of combination therapy consisting of one (1) intravenous (IV) dose of VRC-HIVMAB075-00-AB (VRC07-523LS) followed by 10 oral (PO) doses of Vorinostat (VOR) taken every 72 hours. Each series will last approximately 1 month and the two series will be separated by at least one month. Combination ART is maintained throughout the study. Participants will be on this study for approximately 28 weeks (or about 7 months). The purpose of this study is to: - Evaluate the safety of two series of a VRC07-523LS infusion followed by multiple oral doses of VOR - Determine if combining VRC07-523LS and VOR can have an impact on non-active HIV virus.
The primary objective of this study is to evaluate the efficacy and safety of fixed dose combination (FDC) bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in adults coinfected with both HIV-1 and hepatitis B. As this is a switch study, all eligible subjects enrolled will be switched from their current antiretroviral regimen to B/F/TAF will be followed on treatment for 48 weeks.
The purposes of this study are to find out if: metformin can be combined with anti-HIV drugs to reduce systemic inflammation measured by the determination of cytokines and other series of serum markers. To determine if the concomitant administration of metformin with TARA improves the immune function on the CD4 T cell count and its relation with the CD8 T cells, during the treatment and after its interruption. To this end, in the present study, patients with prediabetes (who meet the fasting impaired glucose criteria) will be identified and treated with metformin or placebo for 8 weeks, receiving stable TARA and with a CD4 + level> 200 cells / μL. 40 patients from the HIV Unit of the Civil Hospital of Guadalajara "Fray Antonio Alcalde" will be included in this study and the intervention will last 8 weeks.
This is a randomized study for participants treated with tenofovir-based antiretroviral drug regimens with a history of suboptimal adherence (detectable HIV RNA twice over the last year). Eligible participants are enrolled, receive routine adherence counseling and are randomized to receive an AdhereTech "smart pill bottle" or not (open label). The "smart pill bottle" quantitates the number of tenofovir-containing pills taken and sends this to a centralized server; if a dose is missed, the participant is contacted by either phone or text. Participants are assessed at baseline and weeks 4, 8, and 12 for tenofovir diphosphate (TFV-DP) levels (by plasma and dried red blood cell spots), HIV RNA level, and adherence using a standardized questionnaire. Primary outcome is change in TFV-DP levels from baseline in the 2 groups.
