Active clinical trials for "HIV Infections"

The mai purpose of the study is to evaluate the safety and to establish the recommended dose of iHIVARNA-01 as a new therapeutic vaccine against HIV

Since there is no cure for HIV, therefore antiretroviral therapy must be taken life-long. Some of the HIV medications can negatively impact the health of the bone and is even more exacerbated in perinatally HIV-injected children and adolescents because this is the period when the bone peaks. Bone loss during this period can be devastating and increase the risk for developing weak bones later in life. Supplementation of calcium and vitamin D have not been well studied in HIV-infected children and adolescents in developing countries. Therefore it is not clear whether higher doses of these supplementations can thwart the damages or not.

New and recently EMA/FDA approved direct acting antiviral (DAA) combination therapies cure 95% or more of the patients chronically infected with HCV genotype 1 and 4. Grazoprevir (MK-5172) and elbasvir (MK-8742) combination therapy is such a, albeit not yet EMA/FDA approved combination DAA therapy. It is likely that the synergistic effect of the host's immune response and antiviral therapy when given during the first 6 months of HCV infection makes antiviral therapy during acute HCV infection more effective. In this study the investigators would like to document that treatment of acute HCV with grazoprevir (MK-5172), elbasvir (MK-8742) is effective and can ben shortened from 12 to 8 weeks for HCV genotype 1 and 4 infection without substantial loss in efficacy. Study design and intervention: Prospective open label interventional clinical trial in which 80 acute HCV genotype 1 or 4 patients co-infected with HIV will receive 8 weeks of grazoprevir and elbasvir (a once-daily combination tablet). Study population: 80 Adult HIV positive patients with an acute HCV genotype 1 or 4 infection from 10 HIV treatment centers in the Netherlands and Belgium will be included. Primary endpoint: Sustained viral response (SVR) 12 weeks after the end of therapy in ITT study population (=genotype 1 and 4).

This is an open-label, single sequence, 4-cycle, 4-treatment, drug-drug interaction (DDI) study in healthy female subjects on oral contraceptives (OC). There is no formal research hypothesis to be statistically tested. It is expected that coadministration of BMS-663068 with OC will not affect the pharmacokinetics (PK) of either ethinyl estradiol (EE) or norethindrone (NE).

The purpose of this study was to evaluate the safety and tolerability of ruxolitinib in HIV-positive adults who were virologically suppressed and who were on antiretroviral therapy (ART).

In order to define the safe windows for co-dosing of metal-cation antacids with once daily administered raltegravir, this study will evaluate the effect of both calcium carbonate and magnesium/aluminum hydroxide antacids on the pharmacokinetics of raltegravir, due to dosage of 1200 mg raltegravir in HIV-infected participants already taking 400 mg raltegravir twice daily as part of their HIV treatment regimen.

The purpose of this study is to evaluate any change from baseline in bone mineral density (BMD) in subjects following the switch from a triple antiretroviral therapy (ART) regimen containing Tenofovir disoproxil fumarate (TDF) to the nucleoside reverse transcriptase inhibitor (NRTI) - sparing two - drug regimen of dolutegravir (DTG) + rilpivirine (RPV) in subjects participating in the parent studies 201636 and 201637 (SWORD-1 and SWORD-2). This open-label, parallel group, study is a sub-study which will recruit subjects who are receiving ART regimens which include TDF at the time of randomization to receive treatment in one of two identical parent studies 201636 and 201637 (SWORD-1 and SWORD-2). These are Phase III, randomised, open-label, multicentre, parallel-group, non-inferiority studies evaluating the efficacy, safety, and tolerability of switching to DTG plus RPV from current integrase inhibitor (INI)-, non NNRTI-, or protease inhibitor (PI)-based antiretroviral regimen in HIV-1-infected adults who are virologically suppressed, having HIV-1 ribonucleic acid (RNA) levels <50 copies per millilitre (c/mL). Randomisation in the parent studies will be stratified by baseline third agent class (INI, NNRTI, or PI), age group (< or =>50 years old) and participation in this Dual energy X-ray absorptiometry (DEXA) sub-study, therefore there will also be balance across the treatment arms in this sub-study both overall and with respect to baseline third agent class and age at entry. The study population will include approximately 75 evaluable subjects recruited from the Early Switch DTG + RPV treatment group of the parent studies 201636 and 201637, and approximately 75 evaluable subjects from the Late Switch group who continue their current antiretroviral therapy (CAR) through to Week 52 across both the 201636 and 201637 (SWORD-1 and SWORD-2) studies. Subjects participating in study 202094 will have DEXA scans performed at Day 1 and at study Weeks 48, 100 and 148 in parallel with the corresponding scheduled visits in the parent studies.

The purpose of this study is to determine efficacy of the combination of low dose of Tenofovir, Efavirenz and Lamivudine in treating HIV-infection.

HIV replication can be effectively suppressed and acquired immunodeficiency syndrome(AIDS) can be prevented with highly active antiretroviral therapy (HAART). However, HIV-infected people must remain on treatment continuously to avoid viral rebound and progression to AIDS. HIV persistence is thought to stem primarily from the presence of integrated copies of the proviral genome within long-lived cells. Because active viral gene expression causes cell death due to viral cytopathic effects and the immune response, long-lived cells likely harbor transcriptionally silent, latent provirus. HIV-1 persistence in long-lived cellular reservoirs remains a major barrier to a cure. HDACi have the potential to activate ("Kick") these latently infected cells. This will make the HIV infected cells visible to the immune system; the immune response and antiretrovirals(ARVs) will be able to attack and eliminate ("Kill") the infected cells. The purpose of this study is to evaluate the safety and efficacy of multi-dose Chidamide in combination with antiretroviral therapy in HIV-infected adults with suppressed viral load.

Cabotegravir is being developed for the treatment of human immunodeficiency virus (HIV) 1 infection. Specifically, it is being developed as a component of a 2-drug maintenance regimen (post-induction of viral suppression) that includes rilpivirine. Rilpivirine requires food for optimal absorption; therefore the recommended intake of cabotegravir in the planned Phase 3 treatment studies is with food regardless of fat or calorie content, when administered along with rilpivirine. This is a single-center, randomized, open-label, two-way crossover study in healthy adult subjects to assess the effect of a high fat meal on the single dose pharmacokinetics of CAB 30 mg. Approximately, 24 subjects will be enrolled in the study and will be screened for 30 days. Twelve subjects with at least 10 hours of fasting will be randomized to receive a single dose of cabotegravir orally (Schedule 'A'). The remaining 12 subjects will receive a single dose of cabotegravir orally along with high fat meal (Schedule 'B'). After 15 days, the subjects earlier undergoing 'Schedule A' will be switched to 'Schedule B' and those undergoing 'Schedule B' will undergo 'Schedule A'. All the subjects will be followed up to 30 days from the day of receiving first dose of cabotegravir to evaluate the effect of a high fat meal on the pharmacokinetics of cabotegravir.
