145 Clinical Trials for Various Conditions
MATCH is an observation study of HIV-infected adults on effective antiretroviral therapy (ART) and demographically matched uninfected adults to evaluate muscle and aging.
Advances in antiretroviral therapy (ART) have resulted in increased survival of the HIV-infected population; however, this gain in longevity is associated with an increased risk of cardiovascular disease (CVD). Although ART and traditional risk factors contribute to CVD in this population, heightened markers of immune activation, inflammation, and coagulation independently predict morbidity and mortality, suggesting that dysregulation of these systems plays a significant role in the increased risk of CVD. The investigators believe that platelet activation is an important driver in HIV-associated immune activation, inflammation, and coagulation, leading to an increased CVD pathophysiology and risk. Platelets initiate thrombus formation and also play a key role in vascular inflammation by releasing pro-inflammatory mediators and cross-talking with other relevant cell types including leukocytes. Researchers have described platelet hyperreactivity in chronic HIV infection. Importantly, the investigators demonstrated that one week of anti-platelet therapy (aspirin) decreased platelet activation and immune activation, with an improved trend in inflammation and immune parameters. The overall hypothesis is that platelet activation is a major driver of immune activation, inflammation, and thrombosis in ART-treated HIV infected patients. The purpose of the proposed proof-of-concept study is to understand the mechanism(s) by which anti-platelet therapy improves immune and inflammatory parameters in chronic HIV infection. To test this, the immune modulating and anti-inflammatory effects of 24 weeks of the anti-platelet drug aspirin as compared to the anti-platelet drug clopidogrel will be evaluated. Given their different mechanisms of action and inhibitory potency, the investigators can differentiate whether the potential benefits are mediated via inhibition of arachidonic acid (aspirin) or inhibition of ADP (clopidogrel) or by the antithrombotic activity. A secondary goal is to perform multidimensional assays of platelet activity and thrombogenicity alongside immune activation assays and careful assessments of traditional risk factors and medication regimens, to understand which parameters are highly associated with thrombogenicity.
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 overall aim of the BREATHER trial is to evaluate the role of Short-Cycle Therapy (SCT) in the management of HIV-infected young people who have responded well to antiretroviral therapy (ART) and to determine whether young people with chronic HIV infection undergoing Short-Cycle Therapy of five days on ART and two days off maintain the same level of viral load suppression as those on continuous therapy, over 48 weeks. To assess the advantages and disadvantages of the strategy, the incidence of toxicities, immunological control, resistance mutations, acceptability, quality of life and adherence to the randomised strategy will also be compared. Importantly, because of insufficient data on short-term viral load rebound after stopping ART in this population, the trial will incorporate an initial pilot phase in selected centres, to assess the safety of the SCT strategy by evaluating detailed HIV-1 RNA profiles of participants on the SCT strategy.
The purpose of this study is to examine the safety, tolerability, and immune response to killed-whole HIV-1 (SAV001-H) vaccine as a primary vaccination regimen in HIV infected individuals.
The purpose of this study is to find the best tests to use to investigate the differences between older and younger people with HIV disease. Test to be included will measures of memory, learning, activity levels, sleep patterns, emotional well-being and sexual health.
This study will examine whether a computerized, self-administered assessment of patient medication adherence and health behaviors, plus support for adherence, improves the ability of clinicians to identify adherence problems and leads to better adherence.
The objective of the study is to compare two different doses of Peg-INF-α-2A (90 or 180 ug/wk) for their ability to maintain viral control when initiated 5 weeks before ART (antiretroviral therapy) interruption in HIV positive, ART-suppressed subjects (viral load \<50 copies/ml) as determined by observing the percentages of viral load measurements \<400 copies/ml between the two arms over a 24-week period, corresponding to the Pegasys monotherapy period (exclusive of dual ART/Pegasys 5-week period). Primary analysis will be an "intent to treat" analysis and will address the hypothesis that two different doses of Peg-INF-α-2A (90 and 180 ug/week) will be similarly effective at inhibiting viral replication.
This study will test the safety and immunogenicity of the gp120/NefTat/AS02A vaccine candidate in individuals with chronic HIV-1 infection successfully treated with HAART. The rationale for this study is based on previous scientific experiments, including data indicating that this vaccine can elicit strong HIV-1-specific T cell immune responses in humans and monkeys and lead to a retardation of HIV-1 disease progression in animal models of HIV-1 infection. The HIV vaccine to be administered during this study consists of three recombinant HIV clade B viral antigens: the envelope glycoprotein gp120 and two regulatory proteins, Nef and Tat.The antigens are formulated in a proprietary adjuvant, AS02A, comprised of two immunostimulants in an oil-in-water emulsion (gp120/NefTat/AS02A). The vaccine and the adjuvant are manufactured and provided for the study by GlaxoSmithKline Biologicals, Rixensart, Belgium. The drugs will be given by intramuscular (IM) injection at a standard dose of 20 mg together with 0.5 ml of the AS02A adjuvant. Twenty HIV-1 infected individuals will be randomly enrolled into three different study groups, receiving either the gp120/NefTat/AS02A vaccine (10 individuals), the AS02A adjuvant alone (5 individuals) or a placebo (5 individuals). After obtaining informed consent, subjects will have a history and physical exam performed and have laboratory tests to confirm they meet all inclusion and exclusion entry criteria. Women of childbearing potential will have a pregnancy test prior to each injection of the investigational product. Injections with vaccine, adjuvant alone, or placebo will then be performed at weeks 0, 4, and 12. Study participants will undergo close monitoring after each vaccination. Blood samples will be obtained for immunological assays at study baseline (2 times) and weeks 2, 4, 6, 12, 14, 24, and 48. All patients will maintain their antiretroviral treatment regimen during the entire study period.
There is evidence that early and aggressive treatment with antiretroviral drugs can prevent the loss of immune cell function that accompanies HIV infection. This study will use leukapheresis (drawing blood, separating out the white cells and returning the blood to the patient) to obtain blood cells from HIV-infected patients in either the acute or chronic stage of infection who are being treated with early highly active antiretroviral therapy (HAART). Leukapheresis is necessary to obtain enough cells to delineate the response of B cells to CD4+ T cell help, the CD8 factors associated with suppression of viral replication and normalization of immune function, and natural killer function relative to HIV disease. Study participants will be adult (older than 18 years) HIV primary or acutely affected patients (those with a history of exposure to HIV but not yet showing chronic symptoms of HIV disease) and HIV chronically infected patients (those infected with HIV for longer than 12 months or showing other symptoms of HIV disease) who are not receiving HAART at the beginning of the study. The study seeks to enroll 30 primary and 30 chronic patients. Pregnant women will not be enrolled in the study; women who become pregnant will be dropped from the study. Leukapheresis will be performed on each patient before HAART therapy begins and then three times a year. Each session will take between 1 and 3 hours. This longitudinal study will enable researchers to examine the function of certain B cells, natural killer cells, and CD8+ T cells in people who do not have chronic HIV disease and in those who do have the disease and are treated with HAART.
This study will evaluate the effects of intermittent short cycles of HAART (highly active antiretroviral therapy) for treating HIV infection. HAART is a multi-drug regimen that is very effective in suppressing HIV and perhaps slowing or halting progression to AIDS. However, the treatment has significant drawbacks: it cannot completely rid the body of virus; long-term therapy carries a risk of toxicity (harmful side effects); and the regimen is difficult to comply with because many pills and capsules must be taken daily. When patients stop taking HAART, their HIV levels climb again. This study will see if giving HAART in short cycles of 7 days on, 7 days off, can keep viral levels low while maintaining CD4+ T cell counts. HIV-infected people age 18 or older who are receiving HAART and have a viral load of less than 50 copies/ml and a CD4+ T cell count of at least 175 cells/mm3 may be eligible for this study. Candidates will be screened with a medical history and physical examination, blood and urine tests, and possibly a chest X-ray and electrocardiogram. Women of childbearing potential will have a pregnancy test. Participants will be randomly assigned to either continue their current medication regimen or to take HAART in intermittent cycles of 7 days off, 7 days on. Patients will continue treatment for 72 weeks or until viral levels increase or CD4+ T cell counts decline to a level of concern. Upon entering the study, patients will have blood tests to monitor the amount of virus in the blood, CD4+ T cell count, viral resistance to HAART medications, side effects of the drug, and immune response to HIV in the test tube. They will have clinic visits for a history, physical examination and blood draws every month for 12 months. At that time, depending on T cell counts and viral load, the number of visits may be reduced, but never less frequently than every other month. Patients will also undergo leukapheresis-a procedure for collecting quantities of white blood cells-every 3 to 4 months while on the study. For this procedure, whole blood is collected through a needle in an arm vein (similar to donating blood). The blood is circulated through a cell separator where the white cells are removed, and the rest of the blood (plasma, red cells and platelets) is returned through the same needle or through a second one in the other arm. The collected white cells are used for special studies on the level and function of T cells and to detect hidden virus.
To compare Traditional Chinese Medicine versus standard antibiotic therapy consisting of pseudoephedrine ( Sudafed ) plus amoxicillin / clavulanate potassium combination ( Augmentin ) in reducing symptoms and recurrence of acute HIV-related sinusitis. Chronic sinusitis in HIV-infected individuals is a recurrent and persistent infection with potentially serious complications: it can exacerbate pulmonary disease, cause recurrences of life-threatening sepsis, and progress to central nervous system involvement. Symptoms of sinusitis in HIV patients are often refractory to aggressive Western medical management, and antibiotic intolerance can occur. Traditional Chinese Medicine consisting of acupuncture and herbal treatment may provide a low-risk, low-cost alternative to conventional antibiotic therapy.
Hypothesis: Statin therapy will decrease inflammation and slow progression of cardiopulmonary abnormalities in HIV.
This is a multicenter controlled interventional trial. This phase 1 trial is the first study to assess 426c.Mod.Core-C4b adjuvanted with 3M-052-AF + aluminum hydroxide suspension (Alum) in people living with HIV (PLWH).
This study involves researching new approaches to treating HIV infection. Currently, HIV infection is treated with combinations of drugs called antiretrovirals. These drugs protect cells from infection by interfering with the viruses' ability to make copies of itself by infecting new target cells. Though these drugs are very effective, they cannot cure HIV infection and must be taken each and every day at prescribed doses to maintain their beneficial effect. This research study is investigating a new approach that involves an addition to existing medications. The study is investigating a medication called Poly-ICLC (Hiltonol®, Oncovir), which is an adjuvant. Adjuvants are medications that are designed to boost your body's immune responses resulting from a vaccine. The investigators want to test whether Poly-ICLC is an adjuvant that is effective in HIV-infected patients. A vaccine is not given in this study, but just investigating the adjuvant, Poly-ICLC, to determine whether it may be safe and useful in future vaccines that could be used to treat HIV, called therapeutic vaccines. One goal of future therapeutic vaccines is to reduce the virus that remains persistently inside of cells in a dormant or resting state despite treatment with HIV medications. This persistent pool is termed the "latent virus pool" or "viral reservoir". One tactic to reduce this viral reservoir is to first stimulate HIV to start replicating in order to force it out of hiding. Once viral replication occurs, the infected cells may then be recognized and killed by cells of the immune system. Therefore, we also want to see what effect Poly-ICLC has on the virus that lives inside of cells. Specifically, the investigators want to look at whether Poly-ICLC increases the level of virus inside your cells while also improving your immune system's responses. The investigators are doing this research in hope to find new ways to treat HIV infection that may reduce exposure to medications that are called antiretrovirals. Antiretrovirals are medications used to treat HIV infection. They are very effective but have side effects and have to be taken each and every day and cannot cure HIV.
This is a phase 1, single-site study is to evaluate the safety and immunologic and virologic efficacy of ex vivo expanded HIV-1 multi-antigen specific T-cell (HXTC) therapy in HIV-infected individuals with viral suppression on antiretroviral therapy (ART).
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
This phase I trial studies the side effects and the best dose of sunitinib malate in treating human immunodeficiency virus (HIV)-positive patients with cancer receiving antiretroviral therapy. Sunitinib malate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
The purpose of this study is to determine if stopping anti-HIV drugs for a period of time is safe and effective for enhancing the immune function of patients with HIV.
The objective of this study is to test alternative treatment strategies to reduce the frequency of chronic diarrhea among HIV positive individuals. 60 percent of patients with HIV disease in the U.S. will have diarrhea at some point in their illness. Although in general many of the opportunistic infections (OI's) associated with HIV have decreased due to new "drug cocktails", many of these drugs, however, have diarrhea as a side effect. In Asian countries, acupuncture (including moxibustion) has been widely used for the treatment of various gastrointestinal (GI) disorders. However, there are no published studies that test treatment protocols using acupuncture or moxibustion on patients with HIV experiencing chronic diarrhea.
The purpose of this study is to see if it is safe and effective to add interleukin-12 (IL-12) to the standard drug combination (paromomycin plus azithromycin) used to treat cryptosporidiosis in AIDS patients. Doctors would like to find out if the combination of IL-12, paromomycin, and azithromycin is more effective than paromomycin and azithromycin alone. Cryptosporidiosis is a type of opportunistic (AIDS-related) infection seen in HIV-positive patients as their immune systems weaken. It is caused by a parasite that invades the intestinal tract, and it can cause watery diarrhea, stomach cramps, an upset stomach, or a fever. Antibiotics (paromomycin and azithromycin) are usually used to treat cryptosporidiosis. In this study, doctors will look at the effectiveness of using IL-12. IL-12 is a type of protein naturally produced by certain types of cells of the immune system and is believed to be important for immune function. Doctors hope that IL-12 can help boost the immune system in fighting cryptosporidiosis.
By 2015 half of the people living with HIV infection in the U.S. are estimated be over the age of 50, and this cohort of patients with well-controlled plasma viremia is aging at a more rapid pace than their non-HIV peers. Long-term chronic inflammation plays a critical role in premature aging in HIV-infected adults. Markers associated with chronic inflammation, including IL-6, CRP, sCD14 and d-dimer, have not only been shown to be present at higher levels in HIV-infected adults, but are also correlated to a wide variety of morbidities and mortality. The goal of this project is to determine the impact of two different interventions -- Mindfulness-Based Stress Reduction (MBSR) and Health Enhancement Program (HEP) -- on reducing biological markers associated with chronic inflammation in HIV-infected adults with an undetectable HIV viral load. In order to achieve this goal, a pilot RCT with 120 subjects over 50 years old who are on anti-retroviral therapy (ART) will be conducted with the following specific aims: 1) to assess the effect of MBSR and/or HEP on biomarkers of chronic inflammation (IL-6, CRP, sCD14, d-dimer), and, 2) to explore whether changes in psychological well-being (anxiety, depression, fatigue, cognitive functioning) mediate the impact on chronic inflammation. Subjects will be randomized to participation in a group MBSR course or to the HEP group both of which consist of 8 weekly sessions followed by 6 monthly booster sessions. Three time points will be measured: baseline, 8 weeks (immediately after completion of weekly intervention), and 6-months post-completion of weekly intervention. Mixed linear and structural equation model will be used to test the study hypotheses. The proposed study is innovative in that it is the first to explore the impact of a complementary mind-body intervention on chronic inflammation in HIV-infected adults. Given that the consequences of early aging in this cohort will be a burden on the health care system as well as a medical, social and psychological burden on those living with HIV, the study has the potential to have a major public health impact.
This single-site study of self-hypnosis software using an off-the-shelf virtual reality (VR) device (OculusGo™) to determine the software's safety, usability, and preliminary efficacy in pain relief for HIV-associated chronic pain patients. This is funded under the i Prism Funding through Mount Sinai Innovations.
This project is a single-site, two-arm, randomized controlled pilot study examining the impact of a 2-hour version of Mindfulness-Oriented Recovery Enhancement (ONE MORE) training for individuals with HIV and chronic pain.
The study aims to assess safety and tolerability of oral toll-like receptor (TLR) 8 agonist Selgantolimod (SLGN) administered for 24 weeks in participants with both CHB and HIV who have been receiving suppressive antiviral therapy for both viruses for ≥5 years and have qHBsAg level \>1000 (3 log10) IU/mL at screening. The study will also evaluate if TLR8 stimulation with SLGN will reduce hepatitis B surface antigen (HBsAg) titers in the blood.
Chronic pain is highly comorbid among the 1.2 million persons living with HIV, with recent prevalence estimates ranging from 55-67%. Needed are evidenced-based non-pharmacological interventions to improve chronic pain management and reduce the demand for opioids in the United States. The proposed research will address this need by examining the feasibility and acceptability of Tai Chi as a mind-body intervention for chronic pain management in an HIV population.
To determine if decreased production or release of endogenous opioid peptides by peripheral immune cells contributes to hypersensitivity in people with HIV
Chronic pain impacts a large proportion of aging people living with HIV (aPLWH) and involves factors directly related to HIV (neurotoxicity) and psychosocial co-morbidities common in aPLWH (i.e. social isolation and loneliness). The investigators hypothesize that novel interventions that acknowledge these psychosocial co-morbidities may improve the efficacy of chronic pain management and minimize the use of potentially dangerous medications. This grant proposes to adapt and pilot a pain psychotherapy approach using group acceptance and commitment therapy (ACT) in aPLWH with chronic pain.
The purpose of this study is to conduct a randomized control trial of a behavioral intervention delivered by counselors via telephone to determine if this is an efficacious method for improving medication adherence and health-related quality of life for persons who are 50 and older and living with HIV/AIDS and other chronic conditions.
