Filter by:Healthy volunteers are being recruited for this pharmacokinetics study. The objective is to characterize the pharmacokinetic properties of maraviroc alone and when administered with rifabutin and to assess rifabutin and 25-O-desacetyl-rifabutin pharmacokinetics compared to the literature.
Participating countries: France Objectives Principal objective To evaluate, in HIV-1 infected patients receiving effective antiretroviral therapy, the effect of the addition of Rosuvastatin (dose of 20mg/day) for 3 months, on CD8 T cell activation as assessed by the proportion of peripheral CD8 T cells that co-express the activation markers CD38 and HLA-DR Secondary objectives To evaluate the effect of Rosuvastatin administration on residual CD4 and CD8 T cell activation To evaluate the effect of Rosuvastatin administration on the main serum soluble biomarkers of activation (CRP- HS, D-dimers, IL-6 and soluble CD14) To evaluate the effect of Rosuvastatin administration on CD4 T-cell count and on the CD4/CD8 T-cell ratio To study the relationship between the level of immune activation and the level of residual HIV replication in plasma To study the effect of Rosuvastatin administration on lipid profiles and the correlation between the HDL cholesterol and the CD4/CD8 T-cell ratio To evaluate the tolerance of Rosuvastatin at the dose of 20 mg/day
This study was done with people who were infected with HIV, but did not show any signs of having HIV. They were also feeling well without taking HIV medication and had low or undetectable levels of the virus in the blood. The purpose of this study was to see if taking HIV medication (antiretroviral therapy [ART]) would reduce immune activation (a signal that the body is fighting an infection) in people who have HIV, but did not show symptoms. Also this study helped determine how safe the drug was and how well people reacted to the drug. For this study, the following antiretroviral therapy (ART) was be provided in the form of a single tablet that contains three different drugs: emtricitabine/rilpivirine/tenofovir disoproxil fumarate (FTC/RPV/TDF). These drugs were combined as one tablet which was approved by the Food and Drug Administration (FDA) as a single pill to treat HIV infection. The HIV medication provided was one of the recommended treatments for HIV, including people with low viral loads (how much HIV you have in your body) who were taking HIV drugs for the first time. The risks seen with this HIV medication were the same that one would encounter when taking these drugs outside of the study.
In resource-limited setting, concerns remain regarding the emergence of virologic failure and high-level drug resistance mutations (DRM) during WHO recommended first-line antiretroviral therapy (ART) with non-nucleoside reverse transcriptase inhibitors (NNRTI) based regimens for Human immunodeficiency virus 1 (HIV1) infected patients. The study hypothesis is that a boosted-protease inhibitor regimen has a better outcome than a NNRTI-based regimen with a low genetic barrier to resistance. The study is a randomized, multicenter, factorial trial (conducted in Congo), in treatment- naïve adults receiving for 96 weeks ritonavir- boosted lopinavir(LPV/r) or nevirapine (NVP) each in combination with tenofovir (TDF) /emtricitabine (FTC) or zidovudine (ZDV)/lamivudine (3TC). The primary end point is the incidence of therapeutic (clinical and/or virologic)failure by study week 24.
A prospective, multicenter, open, randomized Phase 2a trial to confirm a sustained virological suppression defined as HIV-RNA <50 copies/ml of 3 different doses of Fozivudine in context to a standard Zidovudine based antiretroviral therapy regimen after 24 weeks of treatment in ART naïve, non subtype B HIV-1 infected individuals from Tanzania and Ivory Coast.
During the course of HIV infection the number of CD4 cells decreases, resulting in a reduced immunological response and eventually immune deficiency. Vacc-4x is a peptide-based HIV immunotherapy vaccine and is anticipated to strengthen the immune system's response to HIV. All patients participating in this trial have previously received the vacc-4x vaccine in order to reduce the amount of HIV-1 virus in the blood and increase the immune response. The primary objective of this study is to evaluate if a re-boost with Vacc-4x could further reduce the amount of HIV-1 virus and increase the immune response.
During the course of HIV infection the number of CD4 cells decreases, resulting in a reduced immunological response and ultimately immune deficiency. Vacc-4x is a peptide-based HIV immunotherapy and the primary objective is to strengthen the immune system's response to HIV p24. By adding Lenalidomide, an immunomodulatory agent, as a supporting drug, it is anticipated that the effect of Vacc-4x might be enhanced.
The purpose of this research study is to evaluate how easy it is for female HIV- positive subjects taking Complera to comply with the dietary requirement using a food diary in the short term (4 weeks) and long term (24 weeks and 48 weeks) and to determine association between calorie intake and virologic suppression. A secondary goal of the study is to evaluate subjects' attitudes towards contraception.
The study was done to: - test a strategy of using a resistance test to choose anti-HIV drugs - see how well combinations of new anti-HIV drugs work to lower HIV infection - see if taking new anti-HIV drugs together is safe and tolerable - see if text messages improve people's anti-HIV drug-taking behavior (only at sites participating in the adherence study) - in people taking certain combinations of anti-HIV drugs with an anti-TB drug, compare how these drugs act in the body - to see how people do after they stop having frequent clinic visits as part of a research study
This substudy is a prospective, observational, open-label, randomised study within the MARCH study. The purpose of this substudy is to investigate the changes in cerebral function parameters at 5 timepoints over 96 weeks of the three different treatment arms within the MARCH study. The investigators hypothesise that there will be improvements in cerebral function in those patients randomised, as part of the parent study, into the maraviroc arms. the assessments in this CNS substudy will include: 1. Neurocognitive function as assessed by a computerised testing battery called CogState; 2. changes in cerebral metabolites as measured via 1H Magnetic Resonance Spectroscopy (1H-MRS) In those randomised to the maraviroc arms (arms 2 and 3) there is an optional Lumbar puncture at week 48. The cerebrospinal fluid will be used to measure maraviroc levels and an ultrasensitive CSF HIV-1 viral load. These results will be matched with levels in the plasma.
