The Safety and Effectiveness of Adefovir Dipivoxil in HIV-Infected Children

Start date: n/a
Phase: Phase 1
Study type: Interventional

To evaluate the single-dose pharmacokinetic profile and acute toxicity of bis-POM PMEA ( adefovir dipivoxil ) in HIV-1 infected children, and to determine whether age-related differences exist. To ascertain dosages that may be suitable for a multiple-dose evaluation in this patient population. Although the oral bioavailability of PMEA ( adefovir ) is low, the prodrug bis-POM PMEA has resulted in increased bioavailability in adult patients in clinical trials. However, the safety and pharmacokinetic patterns of drugs in infants often differ from those of adults and the direction of the variation is not predictable. This study will assess these parameters of bis-POM PMEA in children.

NCT ID: NCT00000844 Completed - HIV Infections Clinical Trials

A Multicenter, Prospective, Randomized, Double-Blind, Placebo-Controlled Trial of Three Preparations of Low-Dose Oral Alpha Interferon in HIV-Infected Patients With CD4+ Counts >= 50 and <= 350 Cells/mm3

Start date: n/a
Phase: N/A
Study type: Interventional

To evaluate the effects of three preparations of low-dose oral interferon alpha (i.e., Alferon LDO, Veldona, and Ferimmune) on HIV symptoms in HIV-infected patients. To evaluate differences in response to oral interferon alpha according to gender, race/ethnicity, and use of antiretrovirals. Previous or ongoing clinical trials to test the efficacy of low-dose oral interferon alpha have produced different results, and it is not clear whether the differences were due to the interferon alpha products used or to problems in the study design. Therefore, three preparations will be compared to evaluate their potential efficacies.

NCT ID: NCT00000845 Completed - HIV Infections Clinical Trials

A Phase I Safety and Immunogenicity Trial of UBI HIV Lipopeptide Vaccine Component P3C541b in HIV-1 Seronegative Human Subjects

Start date: n/a
Phase: Phase 1
Study type: Interventional

To evaluate an HIV synthetic lipopeptide candidate vaccine component, P3C541b, at two dose levels, administered subcutaneously (s.c.) in a randomized, double-blind, placebo controlled study.

NCT ID: NCT00000846 Completed - HIV Infections Clinical Trials

A Phase I Trial To Evaluate the Safety and Immunogenicity of the UBI HIV-1MN PND Peptide Immunogen, Given by IM Injection, in Combination With the UBI Microparticulate Monovalent HIV-1 MN Branched Peptide Given Orally, in HIV-1 Uninfected Volunteers.

Start date: n/a
Phase: Phase 1
Study type: Interventional

To evaluate safety and immunogenicity of 2 different HIV-1 peptide candidate vaccines, the UBI HIV-1 MN PND peptide immunogen and the UBI microparticulate monovalent HIV-1 MN branched peptide when administered sequentially by 2 different routes of immunization, parental priming followed by oral boosting.

NCT ID: NCT00000847 Completed - HIV Infections Clinical Trials

A Phase I Safety and Immunogenicity Trial of Live Recombinant Canarypox ALVAC-HIV (vCP205) and HIV-1 SF-2 rgp120 in HIV-1 Uninfected Adult Volunteers

Start date: n/a
Phase: Phase 1
Study type: Interventional

To evaluate the safety and immunogenicity of high-titered ALVAC-HIV MN120TMG (vCP205) given sequentially or simultaneously with rgp120/HIV-1SF2 in MF59 adjuvant emulsion in HIV-negative volunteers. ALVAC-HIV vCP205 is a second-generation candidate vaccine that can be used to induce a humoral and cellular response against several antigens. vCP205 expresses proteins from two strains of HIV (MN and LAI). rgp120/HIV-1SF2 expresses proteins from a different strain of HIV. This study will help to show how the immune system responds to proteins from more than one strain of virus.

NCT ID: NCT00000848 Completed - HIV Infections Clinical Trials

The Anti-HIV Effects of Saquinavir Soft Gelatin Capsules Versus Indinavir in Patients Who Have Used Saquinavir Hard Gelatin Capsules for One Year

Start date: n/a
Phase: Phase 2
Study type: Interventional

To determine, in HIV-infected patients, whether switching to a new soft gelatin capsule formulation of saquinavir or to indinavir following prolonged use of the original hard capsule formulation of saquinavir results in an acute decrease in plasma HIV RNA. Resistance to anti-HIV agents occurs with increasing duration of use. In vitro studies have shown that cross-resistance occurs among protease inhibitors, although no clinical trials have been conducted to examine antiretroviral activity with sequential use of protease inhibitors or to determine whether saquinavir resistance can be overcome with higher concentrations of the drug.

NCT ID: NCT00000849 Completed - HIV Infections Clinical Trials

A Study to Test the Safety of Recombinant Interleukin-2 (rIL-2) in HIV-Infected Children

Start date: n/a
Phase: Phase 1
Study type: Interventional

The purpose of this study is to determine the safety and maximum tolerated dose (the highest dose that can be given safely) of recombinant Interleukin-2 (rIL-2) in HIV-infected children. This study also evaluates the effect of rIL-2 on the immune system of these patients. IL-2 is a substance naturally produced by the body's white blood cells that plays an important role in helping the body fight infection. HIV-infected patients do not produce enough IL-2, and it is hoped that the use of rIL-2 may improve immune system function in these patients. First, it is necessary to determine the safety and effectiveness of this drug in HIV-infected children.

NCT ID: NCT00000850 Completed - HIV Infections Clinical Trials

The Effectiveness of GM-CSF in HIV-Positive Patients Who Are Also Receiving Anti-HIV Therapy

Start date: n/a
Phase: Phase 2
Study type: Interventional

The purpose of this study is to see how HIV-positive patients who are taking anti-HIV drugs and have a viral load (level of HIV in the blood) of 1,500 copies/ml or more respond to GM-CSF (granulocyte-macrophage colony-stimulating factor). GM-CSF is a medication that is being tested in HIV-positive patients to see if it can improve their immune systems or if it can lower the level of HIV in their blood. GM-CSF is often given to patients with leukemia or patients who have received bone marrow transplants to increase their white blood cells and to improve their immune systems. Doctors believe that GM-CSF can increase CD4 counts in HIV-positive patients, but this study will also look at how GM-CSF affects viral load.

NCT ID: NCT00000851 Completed - HIV Infections Clinical Trials

Comparison of Stavudine Used Alone or in Combination With Didanosine in HIV-Infected Children

Start date: n/a
Phase: Phase 2
Study type: Interventional

To evaluate the safety and determine the pharmacokinetic disposition of stavudine (d4T) alone and in combination with didanosine (ddI), and whether concurrent administration alters the disposition of either drug. To compare d4T versus d4T plus ddI with respect to short and long term changes from baseline in plasma HIV RNA concentrations. To determine the relationship, if any, between drug exposure and viral burden. In a pilot study of d4T and ddI given to eight children with advanced HIV for 24 weeks, the three children with baseline counts greater than 50 cells/micro liter experienced a 20% increase in their CD4+ lymphocyte counts. Based on these results, controlled trials of the same regimen for children with less advanced HIV disease should be undertaken.

NCT ID: NCT00000852 Completed - HIV Infections Clinical Trials

A Pilot Study of Allogeneic Lymphocyte Transfer in HIV Infection

Start date: n/a
Phase: N/A
Study type: Interventional

To examine, in HIV-infected patients, the safety of allogeneic lymphocyte transfer (i.e., infusion of white blood cells taken from an HIV-negative parent, sibling, or adult offspring who has a compatible blood type). To measure the distribution and survival of allogeneic lymphocytes in the circulation of HIV-infected patients, and to determine whether their infusion results in enhanced immunity. To determine whether enhanced immunity is passively transferred or actively induced. There is evidence that periodic infusion of allogeneic lymphocytes obtained from the peripheral blood of HLA-matched HIV-1 seronegative siblings of patients with AIDS can, in some instances, restore the number of circulating CD4+ lymphocytes. However, more controlled studies are needed to better quantitate the immunologic reconstitution seen with this type of therapy.
