Filter by:This was a clinical trial in HIV infected patients with tuberculosis. The study assessed whether the addition of prednisolone, a type of steroid medication, to the standard treatment for tuberculosis improved immune and viral outcomes in the patients. The study demonstrated that prednisolone increased the CD4 cell count as was hoped, but the beneficial effect was short-lived and was gone within 4 months of stopping therapy. Therefore, the use of prednisolone for tuberculosis in HIV infected patients is not recommended at this time.
This study compares three different tuberculosis (TB) prevention regimens against the standard regimen of 6 months of isoniazid. It is being conducted in Soweto, South Africa. People who are HIV positive and have a positive tuberculin skin test without signs of active tuberculosis may join.
This study will evaluate whether the HIV vaccine ALVAC vCP1452 given in combination with interleukin-2 (IL-2), also known as aldesleukin, can increase immune system function in people with HIV infection.
This study will evaluate the safety of and immune responses to a dendritic cell vaccination for HIV-1 infection. The vaccine will be made from a patient's own cells combined with small fragments of HIV-1 (made synthetically in a laboratory). These cells will be administered back to the patient either into a vein (intravenously) or the skin (subcutaneously).
The purpose of this study is to determine the safety and immune system response to the TBC-3B HIV vaccine when it is injected either into the groin area or into the arm. The goal is to determine which injection site is better at producing a particular type of immune response. This study is not evaluating the effectiveness of the vaccine, so volunteers must maintain low risk behavior for HIV transmission throughout the study.
This is an open-label, randomized, parallel group pharmacokinetics trial of tipranavir/ritonavir (TPV/RTV), alone or in combination with RTV-boosted saquinavir (SQV), amprenavir (APV) or lopinavir (LPV), plus an optimized background regimen, in multiple antiretroviral (ARV) experienced HIV-1 patients. The primary objective is to determine the safety and pharmacokinetics of: TPV/RTV given with an optimized background regimen (OBR) and TPV/RTV given in combination with saquinavir, amprenavir, or Kaletra® and an optimized background regimen (OBR).
Pegylated interferon (PEG-interferon) and ribavirin are accepted treatments for hepatitis C virus (HCV) infection. However, HCV infection progresses differently in patients who are coinfected with HIV and in hemophiliacs. This study will evaluate the effectiveness of PEG-interferon and ribavirin for treating HCV in HIV infected hemophiliacs.
This study will examine the safety and effectiveness of the experimental drug bevacizumab for treating both non-acquired immune deficiency syndrome (AIDS) and AIDS-associated Kaposi's sarcoma (KS). KS tumors depend on the formation of new blood vessels for their growth. Bevacizumab is an antibody to a protein called vascular endothelial growth factor (VEGF) that is produced by the body and is involved in blood vessel growth. Bevacizumab may block the action of VEGF, and thus help shrink KS lesions. Patients 18 years of age and older with Kaposi's sarcoma that is restricted to the skin and is not life threatening may be eligible for this study. Candidates will be screened with a medical history and physical examination, blood and urine tests, electrocardiogram (EKG), chest x-ray, and, if needed, imaging studies to evaluate internal tumors. Participants will receive bevacizumab intravenously (by vein) once a week for 2 weeks and then every 3 weeks at the National Institutes of Health (NIH) Clinical Center. The first infusion takes about 90 minutes, the second takes about 60 minutes, and subsequent infusions take about 30 minutes. Infusions may take longer, however, if the drug is better tolerated at a slower infusion rate. Patients will be evaluated with the following tests and procedures: - Physical examination, assessment of drug side effects, measurement of KS lesions, and photographs of lesions once a week for the first 6 weeks of therapy, and then every 3 weeks. - cluster of differentiation 4 (CD4) cell counts and human immunodeficiency virus (HIV) viral load in HIV-positive patients every 12 weeks. - Biopsies of lesions: upon entering the study, at week 12, and at the time of a response of the tumor to therapy or at the end of treatment, if treatment ends at week 18 or later. - Additional biopsies, if requested. (Additional biopsies are not required.) - Other procedures, such as computed tomography (CT) or magnetic resonance imaging (MRI) scans, if medically indicated. Patients may continue bevacizumab therapy indefinitely if they are benefiting from it, as long as they have no substantial toxicity or other conditions that would cause them to stop receiving it and the protocol remains open.
The purpose of this study is to determine any adverse effects of PRO 542 after administration and to determine the anti-HIV effects of PRO 542 in the patient.
The purpose of this study is to evaluate the effect of starting anti-HIV drugs in HIV infected patients who are being treated for opportunistic infections (OIs). This study will follow two patient groups: those who received anti-HIV drugs soon after being diagnosed with an OI and patients with OIs who deferred beginning anti-HIV drugs until after recovering from the OI.
