Filter by:The purpose of this study was to see if antiretroviral therapy (ART) is safe and works at getting rid of malaria in blood and to see whether one type of ART is better than another. This study may offer information for further research in looking at whether ART plays a role in the prevention and treatment of malaria.
Background: Despite the introduction of highly effective antiretroviral therapy (ART) regimes, which control the HIV infection and results in increases in CD4 cell counts and an undetectable viral load, many patients suffer from increased morbidity. There is evidence that presence of antibodies against the C5 region of gp120 strongly correlates with slower disease progression, and that loss of antibody responses to this region are associated with progression. Investigational product: Vacc-C5 is a single heterodimeric peptide-based HIV therapeutic vaccine corresponding to the C5 region on gp120 and the external domain of gp41. The vaccine is intended to create a non-neutralizing antibody against C5 region. Study objectives: 1. To evaluate safety of the vaccination regimens 2. To evaluate C5-specific humoral immune responses (antibodies), T cell responses, T cell activation markers and other immune markers.
The purpose of this trial is to evaluate the safety and immunogenicity of the therapeutic vaccine candidate VAC-3S in HIV-1 infected patients under AntiRetroviral Therapy (ART) with undetectable viral loads.
HIV-infected people can have an increase in inflammation in their body organs, even after taking anti-HIV medicines. Sevelamer carbonate is used to bind phosphate in dialysis patients. It can also bind endotoxin in the gut and lowers endotoxin levels in the blood of dialysis patients. Sevelamer carbonate decreases the inflammation endotoxin causes in dialysis patients. A5296 is a phase II, single-arm study to evaluate the effect of 8 weeks of sevelamer carbonate administration on markers of microbial translocation and T-cell activation in the blood in chronically HIV-infected subjects not receiving ART.
This is a open controlled trial in which 48 HIV-1 patients successfully treated with EFV/FTC/TDF will be randomized to one of 4 groups in equal proportion between arms (1:1). The four arms are as follows: Arm I: EFV / FTC / TDF (n = 12) Arm II: EFV / FTC / TDF + LST (n = 12) Arm III: FTC / TDF + MK-0518 (n = 12) Arm IV: FTC / TDF + LST + MK-0518 (n = 12) The allocation will take place in two phases: Phase I: 24 patients 1:1 receiving EFV/FTC/TDF vs. EFV/FTC/TDF + Losartan If losartan arm shows benefits we will proceed to the second phase: Phase II: 24 patients 1:1 to receive FTC/TDF+ MK-0518 versus FTC/TDF + MK-0518 + losartan. Patients will be followed up during 12 months to determinate the proportion of patients with decreased collagen deposition in TL equal to or greater than 50%.
Since people started taking HIV medications, illnesses related to AIDS have decreased, but other serious illnesses like heart disease (heart attacks) and certain kinds of cancer have increased. Studies show that HIV causes changes in the lining of the arteries and also causes inflammation (irritation) inside the body that may play a role in diseases like heart attacks and strokes. The levels of inflammation and artery lining health can also affect how well your brain works. These changes cannot be felt, but can be measured. Artery lining health can be looked at with a test that uses a blood pressure cuff on your arm to see how the artery responds when air is let in and out of the cuff. An ultrasound (machine that uses sound waves) is used to look at the artery during the test. This test is called Flow Mediated Dilation or FMD for short. Inflammation can be checked with blood tests (blood tests that measure this irritation inside the body that you cannot feel). HIV medications can improve the artery lining health and can partially lower levels of inflammation in the blood; however, these levels of inflammation may not be able to return back to normal. Pravastatin sodium is a medication that is approved by the Food and Drug Administration (FDA) for treating high cholesterol. Pravastatin sodium has also been able to improve the health of the lining of the arteries and lower the level of inflammation in people with other diseases, but has not been studied or approved for this purpose in people who have HIV. This research study will look at the effects of two types of medications used separately or together on the health of the lining of arteries and levels of inflammation in the blood: Atripla (a HIV medication) and pravastatin sodium. This study will also look at the effects of Atripla and pravastatin sodium on cholesterol levels, tests that measure how well you can think and calculate (tests of neurocognitive function), and at the effects of Atripla on the levels of pravastatin sodium in the blood.
The study will assess whether Atazanavir/ritonavir monotherapy provides a non-inferior proportion of virological efficacy with respect to ATV/RTV + 2 NRTIs in patients with stable suppressed viremia and no prior virologic failures.
The combination of GTU-MultiHIV B DNA and LIPO-5 vaccines in a prime-boost strategy is expected to induce strong and diverse HIV-specific immune responses in HIV-infected patients. The investigators will carry out the clinical therapeutic immunization "proof of concept" trial in HIV infected patients. The investigators propose a multi-center double blind randomized versus placebo phase II clinical trial in patients who are chronic asymptomatic HIV-infected patients, with undetectable viral load while treated with a potent combination of antiviral drugs. Patients will continue antiviral therapy combined with either therapeutic vaccination or placebo vaccination. Patients will undergo the procedure which includes a prime with the GTU-MultiHIV B DNA vaccine or placebo administered by IM injections via Biojector (a needle-free injection system) followed by a boost of LIPO-5 vaccine or placebo also given IM. In total, 105 HIV-1 patients will be enrolled: 35 in the placebo arm and 70 in the vaccine arm. Patients will receive antiretroviral treatments and 3 administrations of DNA vaccine or its placebo at weeks 0, 4 and 12 (corresponding to prime vaccinations). They also receive 2 doses of LIPO-5 vaccines or its placebo at week 20 and 24 (corresponding to boost vaccinations). At week 36 antiretroviral treatments will be interrupted until week 48. Patients will be intensely monitored during the treatment interruption period. After start of cART treatment (at the latest in W48), a data collection from clinical car will be carried out. A blood sample with W74 will allow to study the persistence ot the immunizing responses, 1 year after the injection of the last vaccine/placebo. The primary efficacy endpoint is a plasma HIV-1 RNA level at week 48 (e.g. 12 weeks after stopping all antiviral treatment). The main hypothesis for conducting a phase II randomized trial is that immune responses in vaccinated patients may be associated with a better control of viral replication following c-ART interruption as compared to placebo-vaccinated patients.
The purpose of this study is to identify at least one dose of BMS-986001 which is safe, well tolerated, and efficacious when combined with Efavirenz (EFV) + Lamivudine (3TC) for treatment-naive Human Immunodeficiency Virus 1 (HIV-1) infected subjects
The purpose of this research study is to evaluate the immune response to the H1N1 influenza or "flu" vaccine. The "immune response" is how your body recognizes and defends itself against bacteria, viruses, and substances that may be harmful to the body. HIV-1 infected children typically respond more poorly to vaccines compared to uninfected, healthy children and so this study hopes to learn whether or not the body will successfully produce enough antibodies (proteins that fight infection) that will prevent or fight the H1N1 flu virus. There is no information yet on the safety or immune response to this vaccine in children infected with HIV.
