Filter by:We aim at comparing markers of HIV reservoir, monocyte function and immune activation between antiretroviral therapy (ART)-naïve (chronic infection or primary infection), ART-controlled or ART-failing HIV infected adults initiating a dolutegravir (DTG)-based regimen. The investigators' purpose is to measure cell associated HIV-1 DNA, monocyte function [soluble CD14 (sCD14), soluble CD163 (sCD163)], and immune activation [neopterine, interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hsCRP)] biomarkers at different time points between baseline and week 48 post DTG-based regimen initiation in each group.
Research ipotesis is to assess the efficacy and safety of a nucleos(t)ide sparing regimen of atazanavir/ritonavir 300 mg /100 mg QD + Dolutegravir 50 mg QD for the management of virological failure in HIV-1 infected patients. The Primary Objective is to explore the 24-week efficacy of a nucleos(t)ide sparing regimen of atazanavir 300 mg QD/ ritonavir 100 mg QD + Dolutegravir 50 mg QD for the management of virologic failure in HIV-1 infected, integrase inhibitor-naïve subjects.
The principal objective is to evaluate the antiviral efficacy of 48 weeks treatment with the two-drugs combination dolutegravir(Tivicay®) and lamivudine(TEpivir®) in HIV-1 infected patients virologically suppressed with triple HAART.
The purpose of the study is to evaluate whether sitagliptin (Januvia is the brand name for sitagliptin) reduces inflammation and immune activation markers in HIV-infected men and women when compared to a placebo (inactive medication like a dummy pill). The study evaluated whether taking 100 mg of sitagliptin by mouth daily for 16 weeks is safe and effective for HIV-infected persons on antiretroviral therapy (ART) who do not have diabetes. Sitagliptin is a medication that is used to treat people with diabetes (high blood sugar) but also may reduce inflammation in the body.
The study is conducted in two stages and open-label stage of the study. At the first stage of the study, the main purpose was to choose the optimal dose of VM-1500 (20 mg or 40 mg per day) in addition to standard-of-care basic antiretroviral therapy consisting of two NRTIs, in terms of reduction of viral load at Week 12 (<400 copies/ml) in treatment-naïve HIV-1-infected patients. At the second stage of the study, the main purpose was to evaluate efficacy of VM- 1500 (in the optimal dose selected at the first stage of the study) in comparison to Efavirenz added to standard-of-care antiretroviral therapy of two NRTIs, in terms of reduction of viral load at Week 24 to the undetectable level (<50 copies/ml) in treatment-naïve HIV-1 infected patients. Open-label stage of the study continued evaluation of viral load and immunological and safety parameters in HIV-1 patients receiving VM-1500 up to Week 96 and additional PK up to Week 100.
Effect on HIV-1 cell reservoirs of the concomitant administration of intensive chemotherapy and the pharmacological blockade of CCR5 coreceptors: a pilot, open, randomized, and controlled clinical trial.
The goal of antiretroviral therapy should be maintaining undetectable plasma viral load, only present condition to prevent the progression of the disease, improve immune restoration and prevent the emergence of viral resistance mutations. In addition to the individual benefit, antiretroviral treatment reduces the transmission of HIV from an infected person to sexual partners. There is to date no alternative strategy to antiretroviral treatment and antiretroviral therapy, even extended, does not allow viral eradication. The need to maintain antiretroviral therapy for life raises the long-term safety concerns of it, even with the latest molecules. Also, one of the key issues in clinical research is whether after reaching undetectable viral load, antiretroviral treatment can be reduced in order to reduce exposure to molecules. Indeed, this treatment of "maintenance" could potentially need a smaller antiviral potency. On the other hand, reduction of antiretroviral treatment reduces costs, an important consideration in light of new global recommendations of treatment for all patients with T-cells CD4 below 500 / mm3. The alleviation of antiretroviral therapy is to either reduce the number of molecules by making monotherapies or dual therapy, or to realize or intermittent treatment is to reduce the doses of molecules such as randomized ENCORE -1 showing the equivalence of a dose of Efavirenz 400mg instead of 600mg in naive patients. Atalow study has the sense to lower the dose of Atazanavir / Ritonavir in combination with two NRTI to reduce exposure to this molecule and its cost while maintaining an undetectable viral load.
The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of switching abacavir/lamivudine (ABC/3TC) fixed-dose combination (FDC) tablets to emtricitabine/tenofovir alafenamide (F/TAF) FDC tablets versus maintaining ABC/3TC in human immunodeficiency virus type 1 (HIV-1) infected adults who are virologically suppressed on regimens containing ABC/3TC.
This study evaluates the effects of two infusions of 3BNC117 in preventing or delaying rebound of viral load during a brief treatment interruption of standard ART and its safety during a brief analytical interruption of antiretroviral therapy.
Modern antiretroviral therapy (ART) has transformed the clinical care and lived experience of HIV infection. However, increased rates of adverse health conditions that are related to immune activation, such as cardiovascular disease (CVD) and neurodegenerative disease in ART-treated individuals persist. An important cause of this inflammation is the gut CD4 T cell loss and the "leaking" or translocation of luminal gut bacteria and other microbes across the bowel wall and into the bloodstream. The use of complementary and alternative therapies is common among people living with HIV, however their efficacy has generally not been well demonstrated. Probiotics are live microbes that may provide a health benefit to the host and the investigators believe that the simultaneous use of probiotics along with antiretroviral therapy (ART) will improve gut CD4 T cell restoration and function and therefore reduce microbial translocation and immune activation. Probiotic Visbiome consists of a high potency blend of eight different probiotics. The precise mechanism of action of Visbiome is unknown, but preclinical studies have shown that Visbiome may modulate the immune response towards a phenotype that is associated with reduce inflammation, and Visbiome was also protective in a non-human primate model of SIV infection. Therefore, we believe that the "beneficial" bacteria from Visbiome will accelerate the normalization of gut immune cells and function in HIV-infected individuals as they start ART. Early resolution of gut immune cells may normalize microbial translocation and immune activation and will reduce the rates of HIV-associated comorbidities.
