The goal of anti-HIV therapy is to prevent HIV from replicating. Long-term control of HIV requires at least two anti-HIV drugs that are active against the virus. Drug resistance is a problem for many treatment-experienced, HIV-infected people. The purpose of this study was to determine the benefit of adding a nucleoside reverse transcriptase inhibitor (NRTI) to a new anti-HIV drug regimen for the suppression of HIV.
There are few randomized clinical trials in advanced HIV patients. This is a multicenter, randomized, open clinical trial, comparing three parallel groups, to compare the immunological reconstitution and the virological efficacy and safety of three different combinations of antiretroviral therapy given once a day (QD): tenofovir plus emtricitabine plus either efavirenz, lopinavir-ritonavir or atazanavir-ritonavir during 96 weeks in advanced antiretroviral naïve HIV-1 infected patients with less than 100 CD4+ T-cells/mm3. Primary endpoint is the median increase in CD4+ T-cell count at 48 weeks after starting HAART.
The purpose of the study is to look at the effects of two different HIV medications on the body's response to insulin (a hormone that regulates blood sugar levels). This will be done using a method called the 'euglycaemic clamp' The study will also investigate the effects of these drugs on blood fats and on circulating markers in the blood stream related to blood vessels (vascular inflammation markers).
The purpose of the study is to study the effects of switching from an antiretroviral combination that includes two ritonavir boosted protease inhibitors to replacement of these two protease inhibitors with a new protease inhibitor called Darunavir (also boosted with ritonavir). The study will investigate the effect of the switch on viral load (the levels of the HIV virus in the blood), on immunological parameters (CD4 count) and on other safety parameters and also on quality of life. In a subgroup of patients the impact of the switch on the body's response to the hormone insulin will also be measured (Euglycaemic clamp sub group)
The purpose of the study is to look at whether changing directly from one medication for HIV (efavirenz) to a new medication for HIV (TMC125) has any effect on the levels of TMC125 in the blood, compared to when TMC125 is taken without efavirenz having been taken immediately beforehand. The study aims to help the investigators understand whether it is safe to change directly from efavirenz to TMC125 (with no gap between the treatments) in patients who need these treatments. The study will investigate the blood levels of TMC125 when it is taken both once and twice a day.
This observational study is supposed to assess (under conditions of clinical practice in daily routine) whether treatment with Aptivus (tipranavir) in combination with low-dose Norvir (ritonavir) will durably suppress viral load and may achieve suppression of viral load below the limit of detection.
To determine the efficacy and safety of Peginterferón alfa-2a (40 KD) plus Ribavirin in patients who have relapsed or not responded to a previous suboptimal therapy based in Interferon.
The purpose of this study is to identify an optimal dose combination(s) of tipranavir (TPV) and ritonavir (RTV) for antiretroviral treatment naïve HIV-1 infected patients that can be used in pivotal trial by assessing the steady-state pharmacokinetics and short-term efficacy and safety
In this study, we will determine whether treating pregnant and breastfeeding women co-infected with human immunodeficiency virus type 1 (HIV-1) and herpes simplex virus type 2 (HSV-2) with daily valacyclovir will reduce HIV-1 levels in plasma, genital, and breast milk and will decrease the risk of mother-to-child HIV-1 transmission (MTCT).
