Filter by:The primary objective of this study is to evaluate the efficacy of switching from a regimen of dolutegravir (DTG) and abacavir/lamivudine (ABC/3TC) or a fixed dose combination (FDC) of abacavir/dolutegravir/lamivudine (ABC/DTG/3TC) to a FDC of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus continuing DTG and ABC/3TC as the FDC ABC/DTG/3TC in virologically suppressed Human Immunodeficiency Virus- 1 (HIV-1) infected adults.
The primary objective of this study is to evaluate the efficacy of switching to a fixed-dose combination (FDC) of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus continuing on a regimen consisting of boosted atazanavir (ATV) or darunavir (DRV) plus either emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) or abacavir/lamivudine (ABC/3TC) in HIV-1 infected adults who are virologically suppressed.
The primary objective of this study is to evaluate the safety and tolerability of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) in human immunodeficiency virus (HIV-1) infected adults with end-stage renal disease (ESRD) on chronic hemodialysis (HD).
The primary objective is to measure the prevalence of according to the Frascati classification in a HIV-infected population aged between 55 and 70 years (exposed group) and to compare it with the prevalence of HIV-Associated Neurocognitive Disorders (HAND) in unexposed subjects from the general population-based cohort CONSTANCES, matching subjects on age, gender, geographical origin and socioprofessional category.
HIV-1 infected patients with normal peripheral blood CD4+ T-cell counts and undetectable viral load will be recruited in four Belgian HIV reference centers. Selected patients will undergo a two-step screening in which a viral reservoir measurement will be performed and among those with a very low viral reservoir an analytical treatment interruption of their longstanding antiretroviral therapy (ART). There is no randomization foreseen. Patients will receive an intense clinical and laboratory follow-up during 48 weeks followed by 12 weeks post intervention.
This study evaluates the effects of four 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.
This study was done to see if the combination of two anti-HIV medicines, dolutegravir (DTG, Tivicay) and lamivudine (3TC, Epivir) taken once a day, provide a safe, effective, and well-tolerated treatment for HIV. DTG is a type of HIV medicine called an integrase inhibitor; 3TC is a type of HIV medicine called a reverse transcriptase inhibitor. DTG works by blocking integrase and 3TC works by blocking reverse transcriptase, two HIV proteins (enzymes). This prevents HIV from multiplying and lowers the viral load (amount of HIV in the blood). Both DTG and 3TC are currently part of Food and Drug Administration (FDA) recommended regimens along with a third active drug. Since some HIV medicines have side effects and are costly, there is interest in whether HIV can be successfully controlled with fewer than three HIV drugs.
This study seeks to assess the virologic effectiveness of dual therapy (lopinavir/ ritonavir (LPV/r) + lamivudine (3TC)) in treatment-experienced human immunodeficiency virus 1 (HIV-1) infected participants with an undetectable plasma HIV-1 (ribonucleic acid) RNA level (for at least 6 months) at the 48 week time point of treatment in the routine clinical settings of the Russian Federation.
Advances in antiretroviral therapy (ART) have resulted in increased survival of the HIV-infected population; however, this gain in longevity is associated with an increased risk of cardiovascular disease (CVD). Although ART and traditional risk factors contribute to CVD in this population, heightened markers of immune activation, inflammation, and coagulation independently predict morbidity and mortality, suggesting that dysregulation of these systems plays a significant role in the increased risk of CVD. The investigators believe that platelet activation is an important driver in HIV-associated immune activation, inflammation, and coagulation, leading to an increased CVD pathophysiology and risk. Platelets initiate thrombus formation and also play a key role in vascular inflammation by releasing pro-inflammatory mediators and cross-talking with other relevant cell types including leukocytes. Researchers have described platelet hyperreactivity in chronic HIV infection. Importantly, the investigators demonstrated that one week of anti-platelet therapy (aspirin) decreased platelet activation and immune activation, with an improved trend in inflammation and immune parameters. The overall hypothesis is that platelet activation is a major driver of immune activation, inflammation, and thrombosis in ART-treated HIV infected patients. The purpose of the proposed proof-of-concept study is to understand the mechanism(s) by which anti-platelet therapy improves immune and inflammatory parameters in chronic HIV infection. To test this, the immune modulating and anti-inflammatory effects of 24 weeks of the anti-platelet drug aspirin as compared to the anti-platelet drug clopidogrel will be evaluated. Given their different mechanisms of action and inhibitory potency, the investigators can differentiate whether the potential benefits are mediated via inhibition of arachidonic acid (aspirin) or inhibition of ADP (clopidogrel) or by the antithrombotic activity. A secondary goal is to perform multidimensional assays of platelet activity and thrombogenicity alongside immune activation assays and careful assessments of traditional risk factors and medication regimens, to understand which parameters are highly associated with thrombogenicity.
During the past years the treatment of HIV-1 infection has transformed towards chronic treatment. Patients are being treated with antiretroviral drugs for many years and become older. The risk of developing side-effects due to long term antiretroviral therapy is therefore more and more likely. New alternative once-daily maintenance regimes are needed for those who are extensively pre-treated and experience side-effects or toxicity on standard treatment combinations. A possible once-daily, fully active maintenance regimen is the combination of atazanavir (unboosted), dolutegravir and lamivudine (PRADAII regimen). This combination is expected to be a safe, once-daily maintenance regimen with a favorable side-effect profile. The combination suits patients with intolerance and/or resistance to NRTIs, NNRTIs and ritonavir, who have a suppressed viral load. However, for this new combination the pharmacokinetic profile is unknown and there are no data on short-term and long-term safety and efficacy. This study wille therefore asses the pharmacokinetics, safety and efficacy in a small number of HIV-1 infected patients.
