Active clinical trials for "HIV Infections"

This randomized, multi-center, Phase IV, comparative study will assess the efficacy and safety of combined peg-interferon alpha-2a (Peg-IFN-Alpha-2A) and ribavirin therapy for 48 or 72 weeks of treatment and 24 weeks of follow-up in participants with Genotype 1 chronic hepatitis C (CHC), co-infected with human immunodeficiency virus type 1 (HIV-1).

The purpose of the study is to evaluate the bioequivalence between Fixed-dose Combination (FDC) tablet formulation of Dolutegravir (DTG) 50 milligrams (mg) and Rilpivirine (RPV) 25 mg versus co-administration of the separate tablet formulations of DTG 50 mg plus RPV 25 mg, in the fed state. This pivotal bioequivalence study, is to serve as a pharmacokinetic (PK) bridge to the ongoing Phase 3 trials with the separate agents. This study will be conducted under fed conditions to appropriately mimic the conditions in the Phase 3 trials. This is a single-center, randomized, open-label, 2-period, single-dose, crossover study. A minimum of 86 healthy adult subjects will be randomized such that a minimum of approximately 82 evaluable subjects complete the study. The total duration of participation of a subject in this study will be approximately 8 weeks which includes a screening visit within 30 days prior to the first dose of study drug, two treatment periods each with a single dose of study drug and a follow-up visit within 12-17 days after the last dose of study drug. There will be a washout of at least 21 days between each dose of study drug. A blinded (for treatment) review of DTG and RPV plasma concentration data for approximately the first 40 subjects will be conducted. If the within-subject coefficients of variation (CVw%) for either DTG or RPV maximal drug concentration (Cmax) values are >=31%; a sample size re-estimation will be employed and additional subjects (beyond the 86 planned) will be randomized for treatment in the study. Following the re-estimation, it is possible that up to approximately 154 healthy adult subjects (68 new subjects in addition to the planned 86 subjects above) will be randomized such that a maximum of approximately 146 evaluable subjects could complete the study.

This study will be a phase 1, open label, parallel group, three period crossover study to evaluate the effect of dolutegravir (DTG) on the steady state pharmacokinetics of metformin and on the safety and tolerability of dolutegravir and metformin. Subjects will have a screening visit within 30 days prior to the first dose of study drug, three treatment periods, and a follow up visit 7-14 days after the last dose of study drug. Eligible subjects will be assigned to one of the two treatment cohorts. Subjects will receive metformin 500 milligram (mg) after every 12 hours (q12h) for 5 days in Period 1; metformin 500 mg q12h plus dolutegravir 50 mg after every 24 hours (q24h) (Cohort 1) or 50 mg q12h (Cohort 2) for 7 days in Period 2; and metformin 500 mg q12h for 10 days in Period 3. There will be no washout periods between treatments. All doses of study drug will be taken following a meal. Safety evaluations will be collected during each period. Serial pharmacokinetic (PK) samples will be collected for metformin on the last day of each period and for dolutegravir on the last day of Period 2.

HIV infection is associated with premature aging of the immune system. It is believe that the persistent inflammation that accompanies HIV infection is a major contributor to premature immune aging. Fish oil has well-documented anti-inflammatory properties. In this randomized, clinical trial, we're testing whether a 12-week course of fish oil supplementation will reverse premature aging in HIV-infected older adults.

The primary objective of this study is to evaluate the efficacy of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) versus elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) FDC in HIV-1 positive, antiretroviral treatment-naive adults.

GSK2838232 is a novel human immune virus (HIV) maturation inhibitor being developed for the treatment of chronic HIV infection. This study is the first administration of GSK2838232 in humans to establish the initial safety, tolerability, and pharmacokinetic profile following single doses of GSK2838232 and to evaluate the effect of food and ritonavir (RTV) on GSK2838232 in healthy subjects. There will be 2 cohorts in this study. In Cohort 1, approximately 8 healthy subjects will be enrolled (6 active and 2 placebo) at each dose visit. There will be four dosing sessions for each subject with subjects randomized to receive placebo in a random sequence. In Cohort 2, approximately 8 healthy subjects will be enrolled (6 active doses and 2 placebo doses at each dose visit). Cohort 2 will have four dosing sessions for each subject with subjects randomized to receive placebo in a random sequence.

This phase I trial studies the side effects and best dose of cabozantinib s-malate in treating patients with solid tumors that have spread to other places in the body and usually cannot be cured or controlled with treatment and human immunodeficiency virus. Cabozantinib s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This is a 24-week, one arm, open-label, interventional, non-comparative multicenter study to evaluate lipid changes in HIV infected women with hyperlipidemia on boosted PI based regimen after switching their boosted PI to raltegravir at standard dosage with 400mg twice daily. This study aims to study the effect on metabolic profiles by switching hyperlipidemic HIV infected women from a PI based regimen to raltegravir.

This study is being conducted to comply with the Food and Drug Administration (FDA) recommendation that all new non anti-arrhythmic drugs be assessed for cardiac repolarization effects through electrocardiographic evaluation. Therefore, this study will evaluate the effect of GSK1265744 on cardiac conduction as assessed by collection of twelve-lead continuous digital data in healthy adults. This study will evaluate the effect of three doses of GSK1265744 on the QT duration corrected for heart rate (QTc) interval as compared to placebo. Moxifloxacin will be used as a positive control in order to validate the sensitivity of the study in detecting QTc change. This study consists of three treatment periods (each separated by 21 day washout period) followed by follow-up visit 10 to 14 days post last dosing. The total duration of study including follow-up visit will be approximately 62 days. Approximately 42 subjects will be enrolled such that 34 subjects complete dosing and critical assessments.

Background: - The immune system protects the body from infection. But it can also cause harm. For example, the clotting system makes blood clot and protects from bleeding. But blood clots are sometimes harmful. People with human immunodeficiency virus (HIV) infection have increased inflammation and clotting. This may increase their risk for diseases like stroke or heart attack. Researchers want to know how aspirin or HMG-CoA reductase inhibitors (so-called statin medications) affect the immune and clotting systems of people with HIV. Aspirin is a medicine to decrease clotting. Statins are medications given to lower cholesterol and decrease inflammation. Objectives: - To see how aspirin or statins change immune and clotting systems in people with HIV. Eligibility: - Adults 18 and older with HIV and a low viral load, not on aspirin or a statin medication. They must also have either: (1) never taken anti-HIV medications (ARVs), have a suppressed viral load, have stable CD4 counts, and never had an opportunistic infection; or (2) been taking ARVs for 5 continuous years and have a suppressed viral load for more than 3 years. Design: Participants will be screened with medical history, physical exam, and blood and lab tests. Participants will repeat screening tests and have an MRI. An MRI is a way to visualize blood vessels in the neck and head. Participants will lie on a table that slides in and out of a cylinder surrounded by a magnetic field. Participants will take either study drug once daily for 9 months. Participants will have a blood procedure twice. Blood will be removed through a needle in one arm and circulated through a machine that removes white blood cells. The blood, minus white blood cells, is returned through a needle in the other arm. All participants will be observed for 3 months before and after treatment.
