Filter by:Maraviroc is an antiretroviral drug that belongs to the family of the CCR5 coreceptor inhibitors. It has proven to be effective in increasing CD4 lymphocyte counts in both in treated and naïve patients, irrespective of the viral load. The investigators hypothesize that adding Maraviroc to the antiretroviral treatment of discordant patients, defined as those having CD4 lymphocyte counts below 200 cells /mm3 during the last year, could lead to its immunological recovery. 60 patients will be included in this unicentric, prospective, randomized and stratified clinical trial. They will be randomized to either continue with its usual high activity antiretroviral therapy (HAART) treatment or to receive 300 mg of Maraviroc every 12 hours plus its usual treatment. After 24 weeks, lymphocyte counts will be assessed, as well as safety, clinical progression, immunological profile of the patients and the potential benefit of Maraviroc for HIV+ cirrhotic patients.
This is an observational, non-comparative, multicenter, open-label study. Participants will be treated with Raltegravir according to standard clinical practice, and monitored over a total period of 96 weeks. In an extension to the study (Amendment 1), a new cohort of aging participants (≥ 50 years) will be recruited and monitored over a total period of 48 weeks. Participants who stop taking Raltegravir before the end of the 96-week period or 48-week period, respectively, will be followed up for 3 months after discontinuing the drug. The primary objective is to determine the proportion of participants with a human immunodeficiency virus (HIV)-1 viral load < 50 copies/mL after 48 weeks of treatment with Raltegravir.
This is a pilot study to determine the safety and feasibility of lentivirus-transduced T-cell immunotherapy in patients who have failed highly active anti-retrovirus therapy (HAART).
This study will evaluate the safety and tolerability of MK6186 and the change from baseline in plasma HIV-1 RNA after seven consecutive days of dosing.
This study examines the safety of pregabalin over a 6 month period in patients with neuropathic pain associated with HIV infection as an extension of another trial that tests the efficacy of pregabalin.
For several years there has been interest in why some people with HIV-1 progress more slowly to disease and have longer survival without Highly Active Antiretroviral Therapy (HAART) than others. The investigators and others have identified a few HIV positive individuals who can control their viral load for many years without HAART, these rare individuals do not lose their HIV-1-specific cellular immune responses, which are very important for controlling viral load. This group is referred to as long-term non-progressors (LTNP). Unlike LTNP the majority of HIV-1 infected individuals are chronic progressors (CP) who do not make effective HIV-1-specific cellular immune responses, even when on HAART. We propose to use a novel DNA vaccine boosted with immune based therapy (cytokines and hormones) to try to regenerate the missing HIV-1-specific cellular immune responses to make chronically infected HIV-1+ persons more like LTNP. By injecting this novel DNA vaccine and immune based therapy into the people who are already infected with HIV-1, the immune system may be stimulated to mount a greater immune response not only to the vaccines but also to real HIV-1 particles and HIV-1-infected cells.
DCVax-001 is a recombinant protein vaccine designed to prevent and potentially treat human immunodeficiency virus (HIV) infection. The vaccine is composed of a fusion protein containing a human monoclonal antibody specific for the dendritic cell receptor, DEC-205 (CD205), and the HIV gag p24 protein. The vaccine is designed to target HIV antigens directly to endocytic pathways in dendritic cells (DCs) that allow for efficient processing and presentation of multiple HIV peptides on both MHC class I and II products, which will induce HIV-specific CD8+ and CD4+ T cells. This vaccine candidate must be combined with appropriate immunostimulants (adjuvants) to induce immunity to the antigen. In the proposed clinical trial we will use poly ICLC (Hiltonol) from Oncovir, Inc as the adjuvant.
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.
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (behavior in the body) of bevirimat administered for 15 days to HIV-positive individuals.
A double-blind, randomized, placebo-controlled, dose-escalating study to assess the antiviral activity, safety, tolerability, and pharmacokinetics (PK) of the CCR5 antagonist TBR 652 monotherapy dosed orally once daily (QD) for 10 days in HIV 1-infected, antiretroviral treatment-experienced, CCR5 antagonist-naïve patients.
