Active clinical trials for "HIV Infections"

The purpose of this study is to determine whether an intensive, eight session behavioral intervention is superior to standard care in achieving abstinence from cigarettes in smokers living with HIV/AIDS.

Hypothesis: the intracellular concentrations of raltegravir (RAL) and etravirine (ETV) administrated as 800 and 400 mg once a day, respectively, are similar to those obtained with the standard doses of 400 and 200 mg/12h, respectively. Objective: To analyze the plasma and intracellular concentrations of RAL and ETV administrated as 800 and 400 mg once daily respectively compared with standard doses of 400 and 200 mg/12h, respectively, and if they support its once daily administration.

This study will enroll completers of a prior 24 week MEMS cap study of Kaletra adherence, conducted in 2005 - 2006, and repeat the MEMS monitoring for an additional 24 weeks in 2008/2009 on the current antiretroviral anchor drug. The goals of the study are to correlate long-term adherence with virologic outcome, and to explore the stability of MEMS cap adherence measurements over time.

To demonstrate that patients treated with Kaletra have an improvement in their quality of life compared to the quality of life they had with their previous NRTI therapy.

Patients with HIV-1 infection on HAART regimen including 2 NRTI/NtRTIs plus one of the following : 1 PI/ritonavir or ATV/unboosted or 1 NNRTI, will be randomized to switch from the NNRTI/PI to maraviroc (300 mg /12 h) or to continue with the same approach.

The purpose of this study is to determine if vaccination before a structured treatment interruption (STI) is associated with an improvement in immune function, resulting in a delayed and reduced rebound in the amount of HIV virus in the blood.

The goal of this research study is to look at treatments that may help individuals who have HIV/AIDS to stop smoking.

The purpose of this study is to investigate the possibility of an association between changes in neurocognitive function, as measured by a computerised test battery, and the use of two different highly active antiretroviral therapy (HAART) regimens in treatment naïve HIV-1 infected subjects commencing antiretroviral therapy.

This is an open-label, multi-center, randomized, parallel-group, maintenance trial of Serostim® in subjects who have completed a prior Serostim® Human Immunodeficiency Virus-associated Adipose Redistribution Syndrome (HARS) trial (Study 22388). The subjects, who encountered toxicity during the antecedent protocol, will be assigned to a 1 milligram (mg) dose. All other subjects will be randomized in 1:1 ratio, to receive up to 2 mg or 4 mg of Serostim®, beginning from Day 1 of Week 1. Doses will be adjusted downward in subjects weighing less than 55 kilogram (kg). Serostim® therapy will be continued at the assigned doses through Week 12 (Period 1). Subjects, who will encounter toxicity during Period 1, will be assigned to the 1 mg group for Period 2. All other subjects will be randomized in a 1:1 ratio to receive up to 2 mg or 1 mg of Serostim® on a weight adjusted basis. Period 2 therapy will begin on Day 1 of Week 13, continuing through Week 36. Study visits are required at Screening (that is, Final Visit of the antecedent trial), Day 1 of Week 1 (Baseline), and at Weeks 2, 6, 12, 14, 24, 30 and 36.

We hypothesize that a simple bridging ARV regimen that tends to select for virus with a low replicative capacity may tend to stabilize CD4 cell counts and HIV viral load and might be an option to consider in patients with MDR HIV. This strategy will provide them with the bridge they desperately need so that they can await the development of new therapies that when used in combination will give them the best chance in achieving complete virologic suppression.
