Active clinical trials for "HIV Infections"

This protocol represents the third in human study of TUTI-16, and is being conducted to gather additional safety and human immunogenicity (anti-HIV-1 Tat titers) data of subcutaneously administered TUTI-16.

The purpose of this study is to evaluate the acceptability and efficacy of a computer-based tailored information application designed to promote health literacy in persons treated for HIV infection. The study hypothesis is that the application will be acceptable and usable for persons treated for HIV infection, and will improve their levels of adherence to antiretroviral medication treatment.

The objective of this study is to evaluate the effect of boceprevir (steady state) on the pharmacokinetics of a single dose of raltegravir. The effect on the boceprevir pharmacokinetics of a single dose raltegravir will also be evaluated (compared to historical controls). Furthermore, the safety profile of the combination is studied.

Background: Antiretroviral therapy (ART) has been able to improve the lifespan of individuals infected with human immunodeficiency virus type 1 (HIV-1), but ART requires continuous treatment that has substantial consequences on quality of life. Recent research is attempting to determine whether this persistent infection stems from a low-level infection where new cells are continually infected with HIV, or from cells that live for a long time after infection. ART is very active against the virus in new cells, but has no effect on long-lived cells that are already infected with HIV-1 at the start of ART. As a result, new strategies may be necessary to reduce or eradicate these 'reservoir' cells. Interferon is a natural substance made by the body to combat virus infections, and can be made as an injectable drug known as PEGINTRON. Researchers are interested in determining whether PEGINTRON therapy will also reduce the residual low levels of HIV in patients who are already taking ART. Objectives: - To evaluate the effectiveness of PEGINTRON injections on HIV levels in participants currently undergoing antiretroviral therapy. Eligibility: - Individuals at least 18 years of age who have been diagnosed with HIV, are currently undergoing antiretroviral therapy, and have maintained HIV virus blood counts that are not detectable by current commercial tests for at least 12 months before the start of the study. Design: This study will involve separate screening and treatment processes. Participants will be screened with a physical examination and medical history, including blood and urine samples. The screening analysis to determine study eligibility will take several weeks. Participants will have apheresis to provide sufficient numbers of blood cells for evaluation by the study researchers. Eligible participants will begin a 4-week course of PEGINTRON injections using the standard dose of PEGINTRON that is approved for treatment of chronic hepatitis C. Participants will have weekly injections and have frequent blood tests to measure HIV virus levels. Participants who experience problems in maintaining safe numbers of white blood cells during the study may receive injections of filgrastim to increase their white blood cell count. After the 4 weeks of treatment, participants will return for additional blood tests on study days 28, 35, 42, 49, 56, and 84, and Weeks 16, 24, 36, and 48 (i.e., through the end of 1 year after the start of the study).

This phase II, multicentric, national pilot trial is designed to estimate the sustained virological response rate (SVR) following a 12 weeks treatment by telaprevir combined with a 48 or 72 weeks treatment by peginterferon and ribavirin, based upon the rapid virological response (RVR) at week 8 (4 weeks after telaprevir start), and to compare the observed SVR to 20%, a rate determining a significant therapeutic benefit in this population of patients. The primary endpoint will be the SVR defined as undetectable HCV-RNA measured 24 weeks after the end of therapy (EOT).

The purpose of this study is to assess the safety, efficacy, tolerability and pharmacokinetics of four doses of BMS-663068 with Raltegravir (RAL) + Tenofovir Disoproxil Fumarate (TDF). At least 1 dose of BMS-663068 can be identified which is safe, well tolerated, and efficacious when combined with RAL + TDF for treatment-experienced HIV-1 infected subjects.

This is a multicenter, single arm, 48-week open-label study of FDC ELV/COBI/FTC/TDF [Stribild] in acute HIV infection. Study sites will be members of the Duke-UNC Acute HIV Infection Study Consortium. Participants will be enrolled for 96 weeks. Clinical care and study drug (ELV/COBI/FTC/TDF) will be provided for the first 48 weeks. After week 48, clinical care but not study drug will be provided through week 96. A study participant suppressed at week 48 can continue on FDC ELV/COBI/FTC/TDF. The primary hypothesis is that once daily fixed-dose combination elvitegravir (ELV), cobicistat (COBI), emtricitabine (FTC), and tenofovir disoproxil fumarate (TDF) will rapidly reduce viral replication to <50 copies RNA/ml in participants with acute HIV infection. The secondary hypotheses to be considered are 1) virologic response rates as measured by plasma HIV RNA levels will be non-inferior or superior to a historical group of participants from the PHI cohort treated with EFV/FTC/TDF, 2) compared to historical controls treated with EFV/FTC/TDF, plasma HIV RNA will decrease more rapidly in PHI participants treated with ELV/COBI/FTC/TDF, 3) compared to historical controls treated with EFV/FTC/TDF, immune activation as measured by the proportion CD4+ and CD8+ cells expressing HLA-DR and CD38+ will decrease more rapidly in PHI participants treated with ELV/COBI/FTC/TDF, 4)in a subset of participants samples will be obtained from compartments such as the gastrointestinal tract, and lymphoid tissues to assess changes over time in parameters such as HIV-1 RNA, immunologic responses to HIV, and tissue and anatomic reservoirs. We hypothesize that treatment with the ELV/COBI/FTC/TDF will demonstrate improved viral clearance in these compartments as compared to historical controls treated with EFV/FTC/TDF. 5) in a subset of participants who remain suppressed on therapy, resting CD4 cells with replication-competent HIV-1 (latent reservoir) will be quantitated and compared to similar measurements in PHI participants treated with EFV/FTC/TDF. In addition, we will compare these results to those measured in HIV-1 infected participants treated and 6) ELV/COBI/FTC/TDF will be well tolerated, and the proportion of participants who require treatment modification will be less than that observed in participants treated with EFV/FTC/TDF.

The purpose of this study is to assess the safety and ability of panobinostat to re-activate HIV transcription in latently infected CD4+ T-cells among HIV-infected patients on stable antiretroviral therapy

Our general goal is to evaluate the potential effectiveness of recombinant lactoferrin (1500mg bid) for reducing inflammation among HIV positive participants.

Clinical approach to HIV infection treatment is based on the use of highly active antiretroviral therapies (HAART) and recent national and international guidelines for guiding HIV therapy recommend the use of triple-combination therapy using antiretrovirals with 2 nucleos(t)ide inhibitors [N(n)RTI] as backbone plus a third drug to be chosen among a boosted protease inhibitor (PI/r), a nonnucleoside inhibitor (NNRTI) or an integrase inhibitor (II). In spite of evident efficacy of HAART, as demonstrated by survival increasing, long term side effects, as for example the impact on renal function, remain principal problem. In patient with risk factor for renal disease, a reduction of eGRF (estimated Glomerular Filtration Rate) between 90 and 60 mL/min/1,73 m2 could be already considered as a risk condition [1,2]. Efficacy of HAART, with increase of media survival and the parallel decrease of mortality, has underlined the necessity to reflect on long term HAART effects [3]. There are many evidences of HAART-related toxicity that, in spite of the necessity of a life-saving therapy, focus on the additional costs of this situation, in terms of health as well as in terms of economic costs. Particular attention has been focused on the impact of some drugs on renal function, as tenofovir, especially on tubule, without forgetting the modification of lipid and bone metabolisms. According to further studies which have evidenced the potential of some recently introduced molecules [4,5], the investigators had the need to realize a study to deepen the feasibility of a dual-therapy that permit to exclude NRTIs from the backbone, with the aim to prevent NRTIs-related long-term toxicity. The investigators have designed a prospective randomized controlled trial, open-label, with a duration of 96 weeks, to compare the efficacy of a dual-therapy based on rilpivirine 25mg plus darunavir 800mg/ritonavir 100mg QD, in HIV-positive subjects with suppressed viremia from at least 3 months. In fact, there are a few data about association of these drugs, which it has been shown to be safe, well tolerated, and with a strong pharmacological synergy, without nucleos(t)idic backbone, while the necessity to minimize the costs toxicity-related is becoming increasingly compelling. According to clinical experience and literature data, the investigators hope this study shows positive results in term of immune-virological efficacy, as well as in term of decrease of VACS index - a complex parameter which has the purpose to quantify general organic decay - and markers of lipid and bone metabolism, in group which receives dual-therapy versus the group with standard therapy.
