Filter by:The purpose of this study is to evaluate the safety of and immune response to a two-vaccine regimen in healthy, HIV-uninfected adults who have never received an HIV preventive vaccine before.
The primary objective of the trial is to assess the ability of an early and intermittent antiretroviral therapy in maintaining an immunological stability in antiretroviral naive HIV infected adults, to offer a potential alternative strategy to differed and continuous antiretroviral treatment.This is a 2-year phase II, open-label, multicentric "proof of concept" trial. The patients included are treated following a pulse-therapy scheme, i.e. 6-month periods with once daily boosted-PI based therapy in alternance with 6-month periods without antiretroviral therapy. The preferentially recommended treatment of the study is atazanavir boosted with ritonavir, associated with a fixed combination of abacavir and lamivudine or emtricitabine + tenofovir.The patients are closely followed to assess the efficacy and the tolerance of the strategy, with clinical, biochemical, immunological, virological and pharmacokinetic evaluations.
HIV is characterized by frequent immune system activation. Early in the course of infection the body establishes an immune activation "set point" related to the amount of HIV in the blood stream. This set point affects the rate of CD4 cell loss. Without CD4 cells, or with very low levels of CD4 cells, the body cannot fight off illness. This is known as immunodeficiency. If left untreated HIV can lead to extreme immunodeficiency and AIDS. Evidence suggests that by decreasing the rate of immune system activation, immune deficiency progression could be prevented. The purpose of this study is to learn how well chloroquine can reduce the level of immune activation and to test the safety and tolerance of chloroquine in people infected with HIV.
The primary objective of this study is to demonstrate the efficacy of nevirapine extended release (NVP XR) based regimen for HIV-1 infected patients who were receiving nevirapine immediate release (NVP IR) based regimen for at least 18 prior weeks of therapy.
This study focuses on one of the major health issues of Sub-Saharan Africa: multi-parasitism and co-infections. In particular this study aims to elucidate the interaction of helminths with HIV. There is good reason to suspect a detrimental effect of helminth infection on the course of HIV infection. We hypothesize, that treatment of helminths in HIV- and helminth co-infected individuals leads to a reduction of HIV viral load. With a lower HIV RNA level one would expect a slower decline of CD4 cells and hence also a slower progression of the disease. Ideally this would lead to a prolongation of the chronic phase of HIV infection and to a delay in the time when anti-retroviral treatment needs to be started.
This pilot study will provide data on the safety and efficacy of the combination of Raltegravir (RAL) 400mg BID + Atazanavir (ATV) 300 mg BID in Antiretroviral (ARV)-experienced subjects that have a suppressed HIV viral load on a Ritonavir (RTV) boosted Protease Inhibitor (PI) based regimen who are then switched to a regimen of RAL 400mg BID +ATV 300mg BID.
To evaluate the single dose relative bioavailability of GSK1265744 10mg administered in either oral solution fasted, two 5mg tablets fasted, or two 5mg tablets following a moderate meal.
The study aims at comparing the safety, tolerability and efficacy of Mefloquine (MQ) to Sulfadoxine-Pyrimethamine (SP) as Interment Preventive Treatment in pregnancy (IPTp) for the prevention of malaria effects on the mother and her infant.
The objective of this surveillance is to collect information about 1) adverse drug reaction not expected from the LPD (unknown adverse drug reaction), 2) the incidence of adverse drug reactions in this surveillance, and 3)factors considered to affect the safety and/or efficacy of this drug.
The objective of this study is to compare the pharmacokinetics of lopinavir tablets administered to pediatric patients as either whole or crushed tablets. The study is a randomized,open-label, crossover study of pediatric subjects already taking lopinavir/ritonavir tablets as part of their clinical care. THe investigators hypothesize that lopinavir exposure in pediatric patients will be lower after taking a dose of the tablet formulation, crushed and mixed with pudding or yogurt, as compared to the exposure after taking a dose with tablets swallowed whole.
