Active clinical trials for "HIV Infections"

This is an Open-label Phase 3 study in adults with chronic genotypes 1, 2, 3, and 4 HCV infection who are co-infected with HIV-1.

People with HIV infection who are taking antiretroviral therapy (ART) could be at risk for cardiovascular disease (CVD), which can be caused by inflammation. Methotrexate (MTX) is a medication used to treat inflammation in people with rheumatoid arthritis. This study evaluated the safety and effectiveness of low-dose methotrexate (LDMTX) at reducing inflammation in HIV-infected adults.

The purpose of this study is to: find out the intensity and duration of the immune response after multiple injections of the investigational study product AGS-004 made from one's own dendritic cells and one's own strain of HIV; understand the changes in the body's HIV DNA , and HIV-1 RNA in peripheral and resting CD4+ cells prior to and following administration of AGS- 004. find out if low levels of HIV virus that are not detectable by standard HIV RNA assays will decrease following the administration of AGS-004. find out if it is safe to give individuals with HIV multiple injections of AGS-004 made from the person's own dendritic cells and their own strain of HIV. find out if administration of AGS-004 decreases the amount of latent HIV infection in resting CD4 cells

The objectives of this Phase I/II trial is to evaluate the safety, tolerability and immunogenicity of THV01 compared to placebo in HIV-1 infected patients on HAART (highly active antiretroviral therapies). THV01 is composed of two vaccines that derived from the HIV (human immunodeficiency virus): lentiviral vectors. They are non-replicative and not infectious. They will be injected intramuscularly, eight weeks apart. Three doses will be assessed and compared to placebo. Eligible patients must have an undetectable viral load and must be treated by HAART for more than 12 months. They will be randomly allocated to one of the study group and will receive the experimental drugs at one of the three doses or a matching placebo. Their anti-HIV treatment will be alleviated around each experimental drugs' administration to enable THV01 efficacy. HAART will be resumed one week after the second injection. 15 weeks after resumption, HAART will be interrupted. Patients will then be monitored every 2 weeks for CD4+ T cell counts and viral load as well as for thorough assessment of the elicited immune response. Stringent anti-HIV treatments resumption criteria have been implemented, based on the CD4+ T cell counts and the viral load. 38 patients were enrolled in THV01-11-01 study and received the 2 injections. A long-term follow-up of all enrolled patients will be performed for 5 years post-prime administration. This will provide additional data on the safety and the potential long-term risks/benefits associated with THV01. The final study report will be written after the last patient last visit in the long-term follow-up.

This study is a single-center, randomized, open-label, two cohorts, 3-way cross-over design in 36 subjects to assess the oral bioavailability of four new cabotegravir (CAB) sodium salt tablet formulations relative to the current CAB sodium salt formulation being used in the phase IIb studies under fasting conditions. All treatments will be administered as single 30 mg doses of CAB. Safety evaluations and serial PK samples will be collected during each treatment period. A follow-up visit will occur 10 - 14 days after the last dose of study drug. Treatment period doses will be separated by a 14 day washout. Participation in this study will be approximately 12 weeks.

This study will evaluate the safety, tolerability, antiretroviral activity, pharmacokinetics, and pharmacodynamics of an intravenous formulation of deferiprone in HIV-infected subjects.

Phase II trial assessing the efficacy of a reduced dose strategy of darunavir to 400 mg/d in HIV-1 infected patients virologically suppressed under a once daily regimen including darunavir 800 mg/d and two nucleoside reverse transcriptase inhibitors (NRTI), to maintain the viral load lower than 50 copies / mL at 48 weeks of treatment.

The purpose of this study was to evaluate the safety, tolerability, pharmacokinetics (PK), and antiviral activity of an antibody (called VRC01) in HIV-infected adults whose HIV was well-controlled with HIV medicines. The study examined whether VRC01 controlled or delayed the return of HIV viremia when the participants' HIV medicines were briefly stopped during the study.

Background: - A combination of daily drugs (called cART) can keep human immunodeficiency virus (HIV) very low for a long time. But cART can lose effectiveness and cause permanent side effects. If treatment stops, HIV levels go up again. Researchers want to see if a new product can control HIV levels when a person is off cART. Objective: - To see if the new product VRC01 is safe and can control the HIV level in the blood when a person is not taking cART. Eligibility: - Adults ages 18-65 with HIV who are willing to interrupt their treatment for at least 24 weeks. Design: Participants will be screened with: Physical exam Medical history Heart tests Blood and urine tests. Their HIV drugs may be switched. They will keep taking them until a few days after Visit 1. Visit 1: Repeat screening procedures. Participants will also have genetic testing and leukapheresis. For this, blood will be removed through a needle in one arm and circulated through a machine that removes white blood cells. The rest of the blood is returned through a needle in the other arm. They will get the first study drug dose through a thin tube in an arm vein for about 1 hour. For 24 weeks, participants will have 16 visits. They will have blood drawn every visit. At some visits they will repeat the screening procedures and get another VRC01 dose. They may have another leukapheresis. Four weeks after the last dose, participants will restart their cART. For 20 weeks, they will have monthly visits to repeat the screening procedures and discuss new symptoms.

The primary objective of the study was to evaluate the efficacy of nevirapine versus ZDV+3TC (Zidovudine + Lamivudine), when administered in labor and again at postdelivery, in reducing peripartum mother to child transmission of HIV (Human Immunodeficiency Virus). The secondary objective was to assess the overall HIV transmission rate between the 2 groups (intrauterine, intrapartum and postpartum up to 6 weeks) as well as to explore the relationship between infection and timing of maternal dose relative to birth, infant feeding method, maternal peripheral blood viral load, and other potential risk factors for transmission. Following the introduction of the second and third Amendments to the Protocol, 2 substudies were added. The objectives of these substudies were to evaluate the frequency of resistance-conferring mutations to nevirapine (Amendment 2) and to ZDV+3TC (Amendment 3); to determine whether there was a reversion of any resistant virus to the wild type; and to determine if the resistant virus was transmitted from the mother to the child.
