Filter by:In view of the prolongation of patients living with HIV's life expectancy, the question of optimization of ART, which is still a life-long treatment, becomes central. While most patients achieve virological success, their treatments often need to be optimized in order to limit adverse events, drugs interactions and to improve adherence. The switch to dual regimen strategies represent one of the approaches for treatment optimization. Circulating HIV-1 resistant variants can be archived in viral reservoirs, where they can persist for an unknown duration and reemerge in case of therapeutic selective pressure. There is a need to assess the dynamic of archived Drug resistance associated mutations (DRAMs) clearance in cell-associated HIV DNA after a long period of virological control, in the perspective of ARVs recycling. The investigators postulate that it could be interesting in the future to recycle ARV drugs (that where classified as "resistant" in the past) in subsequent regimen. The question is particularly important for 3TC/FTC for subsequent new regimen and for the use of dual regimen (disappearance of M184V). Thus, the investigators propose a retrospective, longitudinal analysis on blood-cell-associated HIV-1 DNA samples in order to investigate by Sanger and Ultra Deep Sequencing the dynamics of decay and persistence of DNA HIV-1 variants harboring key drug resistance-associated mutations to NRTIs, in particular M184V, in patients with sustained virological control for at least 5 years under effective ART.
This is a pilot study investigating the safety of Doravirine (DOR) in combination with Lamivudine (3TC) and Tenofovir Disoproxil Fumarate (TDF) administered over 48 weeks in women of reproductive potential living with HIV-1 switched from Efavirenz or Dolutegravir-based antiretroviral therapy on metabolic and neuropsychiatric outcomes.
This is a pharmacokinetic study investigating the effect of rifampicin on the pharmacokinetics of intracellular tenofovir-diphosphate and plasma tenofovir when coadministered with tenofovir alafenamide fumarate during the maintenance phase of tuberculosis treatment in TB/HIV-1 coinfected participants (EpiTAF)
This is an open-label, single arm, single-centre prospective study to evaluate the feasibility, efficacy and safety of a once daily fixed dose combination regimen, Biktarvy, as a rapid treatment strategy in newly HIV diagnosed patients that come for the first time to the Hospital Clínic HIV Unit Patients with confirmed HIV-1 diagnosis who wish to start ARV treatment immediately will receive bictegravir 50 mg + emtricitabine 200 mg + tenofovir alafenamide 25 mg within the first week since the HIV-1 confirmation during 48 weeks.
The purpose of this study is to demonstrate the effectiveness of Symtuza® in a rapid reinitiation model of care in patients with HIV-1 infection and who are treatment-experienced but have been off of antiretroviral therapy (ART) for 12 or more weeks.
The AELIX-002 trial has been conducted on a cohort of individuals who started cART within the first 6 months after the primary VIH infection, thus increasing the likelihood of observing a certain rate of post-treatment controls (PTC), regardless of treatment efficacy. Although the kinetics of HIV rebound should allow observing differences between placebo and control regarding the post treatment controls rate in case of efficacy of the IMPs, assessing the length and determinants of a post-intervention control (PIC) (i.e., associated with vaccination) beyond 24 weeks is crucial for developing a curative approach to HIV infection. In this regard, an extension of the ATI phase for those individuals with pVL less than 2,000 copies/mL after 24 weeks of ATI in the AELIX-002 offers an unique research opportunity to better understand relevant aspects of the mechanisms involved in the different phenotypes of a PIC and PTC.
The goal of the study is to combine a collaborative and translational approach to evaluate the effect antiretroviral regimen switch to a dolutegravir containing regimen compared to continued treatment with a non- dolutegravir based regimen on on lipid and metabolic profiles, renal function, body composition, vascular function and diet.
This study is composed of two parallel, pilot randomized groups that will obtain preliminary data about the the acceptability, fidelity, and clinical outcomes associated with a multi-component adherence support strategy for HIV treatment and prevention among pregnant and breastfeeding women. The study will take place in Lilongwe, Malawi.
This study will evaluate the intracellular pharmacokinetics and platelet effects of abacavir (ABC), lamivudine (3TC), tenofovir alafenamide (TAF), and emtricitabine (FTC) in persons living with HIV that are receiving these medications as part of standard HIV care. Participants remaining on ABC/3TC- or TAF/FTC-containing therapy will be on study for 4 weeks, and will have two visits: a screening visit and one short PK visit consisting of a single blood draw at week 4. Participants switching from their ABC/3TC-containing therapy will be on study for 3 weeks, and will have nine visits: a screening visit and 8 short PK visits consisting of a single blood draw at Day 0, 1, 3, 7, 10, 14, 18, and 21.
This is a phase 2, single-group, multi-site, open-label study of an islatravir/doravirine (ISL/DOR, MK-8591A) fixed dose combination (FDC) for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in pediatric participants who are virologically suppressed (VS) on antiretroviral therapy (ART) for ≥3 months or are treatment-naive (TN). The primary purposes of the study are 1) to examine the steady-state pharmacokinetics (PK) of ISL in plasma; 2) the steady-state PK of ISL-triphosphate (ISL-TP) in peripheral blood mononuclear cells (PBMCs); and 3) to examine the safety and tolerability of ISL/DOR.
