Filter by:Interleukin-2 (IL-2) increases the number of CD4 cells in HIV-1 infected patients with a CD4 cell count over 200/mm3, but its activity in patients with treatment failure and low CD4 cell counts is unknown. This study will test the efficacy and safety of IL-2 with an optimized antiretroviral regimen in patients with a CD4 count below 200/mm3 and a plasma viral load above 10,000 HIV RNA copies/ml.
Treatment of HIV repairs the immune system, but continuous treatment is expensive and causes side effects. Would it not be better to treat intermittently, e.g. stop treatment when the immune system has recovered, and start again only when damage reappears? That is the question which STACCATO proposes to answer. Approximately 500 patients were recruited for this trial from 2002 to 2004. One third were treated continuously; in two thirds, the treatment was interrupted whenever the CD4 count, a measure of immune recovery, exceeded 350. At the end of 2005, the two treatment groups will be compared in order to see which fared better regarding amount of drugs used, side effects, CD4 counts, and development of resistance to treatment.
The purpose of Study GS-01-934 was to assess the efficacy and safety of two simplified antiretroviral treatment (ART) regimens in ART-naive, human immunodeficiency virus, type 1 (HIV-1) infected participants. The primary objective of the study was to assess noninferiority of emtricitabine (FTC) and tenofovir disoproxil fumarate (tenofovir DF; TDF) in combination with efavirenz (EFV) relative to Combivir (CBV) in combination with EFV in the treatment of HIV-1 infected ART-naive participants, determined by the achievement and maintenance of confirmed HIV-1 ribonucleic acid (RNA) < 400 copies/mL (c/mL) through Week 48, as defined by the United States (US) Food and Drug Administration (FDA) time-to-loss-of-virologic-response (TLOVR) algorithm.
The purpose of this study is to determine the safety and acceptability of a vaginal microbicide in HIV uninfected sexually active women. Study hypothesis: The vaginal microbicide 1% tenofovir will be safe and well tolerated in HIV uninfected women who are in good general health.
The purpose of this study is to evaluate the safety and tolerability of an experimental HIV vaccine. The vaccine will be given with or without IL-12 DNA adjuvant (at three escalating doses of 100, 500, and 1,500 mcg respectively), a substance that helps the body respond to a vaccine. This study will also determine the safety and tolerability of an experimental HIV vaccine boosted with two adjuvants.
Lipodystrophy is characterized by increased cardiovascular disease. Limited strategies are available to increase cardiovascular fitness in this population, particularly among women. Progressive aerobic and resistance training will increase aerobic capacity and improve strength in HIV positive women with lipodystrophy.
This is a Phase II, open-label, roll-over trial to evaluate the long term safety and tolerability of TMC125, administered as part of an individually optimized antiretroviral therapy, in HIV 1 infected subjects. In addition, the antiviral activity and immunological effect of TMC125 as part of an antiretroviral regimen over time, and the evolution of HIV phenotype and genotype will be evaluated.
The purpose of this study is to determine the effect of short cycles of recombinant interleukin-2 (also known as rIL-2 or aldesleukin) given with or without anti-HIV drugs in HIV infected patients. The effects will be compared with a study group that receives no IL-2 or antiretroviral therapy. Study hypothesis: Intermittent aldesleukin, when given without antiretroviral therapy to patients with early HIV infection, will produce no change in HIV viral load and increases in CD4+ T lymphocyte counts comparable to aldesleukin administered with antiretrovirals.
The purpose of the study is to determine the safety and tolerability of PRO 140, an investigational anti-HIV drug, administered via intravenous infusion. Study hypothesis: Single intravenous doses of PRO 140 can be safely administered to humans and will result in measurable concentrations of the product in serum.
Effective, suppressive treatment for HIV infected patients can be a major challenge because HIV progressively destroys their immune systems. CD8 cells isolated from a patient's blood and grown in large numbers in the laboratory may increase a patient's immune system response to HIV. The purpose of this study is to determine if CD8 cells will provide effective antiviral activity against HIV when transplanted back in large numbers into HIV infected patients. Study hypothesis: There are specific cells in the immune system that recognize and can kill HIV-infected cells.
