Active clinical trials for "HIV Infections"

The purpose of this study is to investigate the efficacy, safety, and tolerability of an investigational treatment for patients with Human Immunodeficiency Virus (HIV).

The primary purpose of this study is to: Demonstrate the safety and efficacy of tipranavir/ritonavir (TPV/r) among a racially diverse HIV+ population (males and females) who are three-class (nucleoside reverse transcriptase inhibitor (NRTI), non-nucleoside reverse transcriptase inhibitor (NNRTI), and protease inhibitor (PI)) experienced with documented resistance to more than one PI. Determine pharmacokinetic data in this racially and gender diverse population. Determine the potential utility of using therapeutic drug monitoring (TDM) in improving efficacy outcomes.

Some HIV-infected individuals have a white blood cell marker known as HLA-B*57 that appears to help control the progress of the disease; however, not all who have the HLA-B*57 marker are able to control the infection. This study will examine the effects of giving white blood cells with HLA-B*57 from an individual who controls HIV infection to an individual who cannot control HIV infection, as a form of HIV treatment. All candidates will be screened with a medical history, physical examination, and blood and urine tests. Both donor and recipient volunteers must be HIV-positive individuals 18 years of age or older who have the HLA-B*57 marker and are receiving care. Donor candidates must have positive HIV antibody tests for at least seven years with a recent CD4 cell count greater than 400 cells/mm?, HIV viral load less than 50 copies/mL, and no previous HIV viral load greater than 1,000 copies/mL. Recipient candidates must have positive HIV antibody tests with a recent CD4 cell count less than 400 cells/mm? and HIV viral load greater than 10,000 copies/mL, and must have failed at least two prior combination antiretroviral regimes and are willing to receive or resume combination antiretroviral therapy. Donor volunteers will be excluded if they have taken certain antiretrovirals drugs, have a medical history of cancer or of other blood-borne illnesses, or have other medical conditions that might interfere with the study. Recipient volunteers will be excluded if they have a medical history of malignant cancer or other medical conditions that might possibly interfere with the study. Donors will undergo apheresis to separate white blood cells from circulating blood before the red blood cells and plasma are returned to the bloodstream. The procedure will take up to five hours, and donors will be required to return for additional tests. Donors may be asked to return for further white blood cell donations, a maximum of six procedures per year. Recipients will undergo apheresis to obtain stem cells for possible use in the study, and will be admitted to an NIH Clinical Center inpatient unit to receive an infusion of white blood cells and undergo a series of blood tests both before and after the infusion. The infusion process will take two hours. After being discharged, recipients will be asked to return to the Clinical Center for monitoring and follow-up tests, and may receive further infusions.

Once daily antiretroviral therapy with Viread (tenofovir DF, 300mg) plus Kaletra (LPV/r, 800mg/200mg) will be effective in suppressing and maintaining suppression of HIV RNA to <50 copies/ml in antiretroviral naïve patients through 48 weeks of therapy.

This research work is important for the cure/control of HIV infection. The objectives of a treatment case on HIV patient is essentially to bring down the viral load closer to undetectable level. The studies are depend on the potential influence of 'Kallunk Oxide' on the CD4+ T cells and the effectiveness on surface of HIV-1. The basic study is to break surface protein and directly inhibit a protein's increased functions, not only in the CD4+T cell but also CD3 and CD8+ T cells, by appropriate antidote. The 'Yogaprabhava', the drug's effectiveness, and progressive immunity with diet and lifestyle can be more easily studied.

The purpose of this research study is to see if HIV that persists despite current antiviral therapy can be targeted by new treatments. We will see if adding Raltegravir (MK-0518) and Valproic acid (VPA) to current ART can decrease the amount of latent HIV.

The purpose of the study is to determine if an investigational drug, NGX-4010 (high-concentration capsaicin patch), is safe, tolerable and effective in treating painful HIV-associated neuropathy.

Three or more anti-HIV drugs are taken in combination as part of a treatment regimen. These drug regimens must be closely followed in order to be successful. Having a support person watch a patient take his or her anti-HIV drugs each day may help a patient follow his or her regimen. This study will see if patient-chosen treatment supporters help patients take HIV medicines correctly and improve their health. Study hypothesis: The mean change in CD4 count at 12 and 24 months will be significantly higher in the directly observed therapy-highly active antiretroviral therapy (DOT-HAART) arm as compared to the self-administered arm.

The ideal anti-HIV medications for patients with advanced HIV disease is unknown. There is evidence that anti-HIV regimens that contain protease inhibitors can enhance immune function better than regimens that do not contain protease inhibitors. This is a study that will determine the difference in immune enhancement capabilities between an anti-HIV regimen that contains the protease inhibitor - lopinavir-ritonavir, and a regimen that contains efavirenz. Both medications are recommended as first line treatments for HIV-infected patients. This study will recruit HIV-positive patients that need to start anti-HIV treatment because their CD4+ T-cells are below 200. The usual threshold for starting treatment is a CD4+ T-cell less than 350. Subjects will be randomized to treatment with either an anti-HIV regimen that contains lopinavir-ritonavir or a regimen that contains efavirenz. The study will determine the difference in immune reconstitution over 24 weeks of treatment with study medications. Among the immune parameters that will be measured is the ability of each subject to respond to vaccination with the tetanus-diphtheria vaccine and the 23-valent pneumococcal vaccine. Both vaccines are also recommended for HIV-positive patients but HIV-positive patients tend to have a lower response rate to these vaccines.

Treatment of acute primary HIV infection may improve long-term outcome. However, optimal treatment is still debated. The ANRS 112-INTERPRIM trial evaluates three different therapeutical strategies, combining permanent or intermittent HAART and a cytokine, interferon alpha, in order to determine which combination allows the best control of HIV viremia after 24 weeks of antiretroviral treatment interruption
