Filter by: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.
Cabotegravir (CAB) long-acting (LA) is a promising candidate for human immunodeficiency virus (HIV) pre exposure prophylaxis (PrEP) due to its potent antiretroviral activity and infrequent dosing requirements. Currently, the CAB concentrations achieved in the anatomical sites associated with sexual HIV transmission following the proposed 600 milligram (mg) intramuscular (IM) PrEP dose are unknown. These data will enhance our understanding of CAB distribution to the anatomical mucosal tissue believed to be relevant to sexual HIV-1 transmission and supplement the data to support future PrEP clinical trial development. The primary objective is to determine the PK concentrations of CAB following LA administration in plasma and in vaginal tissue (VT), cervical tissue (CT), and cervicovaginal fluid (CVF) in healthy women and in rectal tissue (RT) and rectal fluid (RF) in healthy men and women following a single 600 mg IM dose. This will be a Phase 1, open label study in healthy subjects to assess the pharmacokinetics of CAB LA in the plasma and mucosal locations associated with sexual HIV-1 transmission: VT, CT, CVF, RT and RF. The study will consist of a screening period, a 28-day oral lead-in phase at a dose of 30 mg per day followed by a 14-42 day washout period, and a single dose of CAB LA 600 mg as an IM (intragluteal) injection with compartmental pharmacokinetic (PK) sampling for up to 12 weeks. Subjects will return for safety assessments and plasma PK sampling at Week 24 and Week 36 post-injection and undergo a follow-up/withdrawal visit at Week 52 post-injection.
This study is a two-arm prospective 1:1 randomised controlled trial comparing the proportion of patients between: Group 1: vorinostat/hydroxychloroquine/maraviroc (VHM) co-administered with anti-retroviral therapy (ART) Group 2: ART only who are able to maintain HIV RNA < 50 copies/ml following treatment interruption. Subjects will be recruited from RV254/SEARCH 010, an acute HIV infection cohort conducted by the Thai Red Cross AIDS Research Centre in Bangkok, Thailand. The study will run for a minimum of 34 weeks from screening.
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).
The goal of this study is to determine if there is a difference in shedding (primary objective) and in immunogenicity and safety (secondary objectives) between HIV-positive and HIV-negative children and young adults who are receiving the quadrivalent live-attenuated influenza vaccine (QLAIV).
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.
This study is a prospective, open-label, randomized, three-arm, dose-escalation exploratory pilot clinical trial involving HIV-1 infected participants treated with suppressive combination antiretroviral combination therapy (cART). The study will test whether combined treatment with the histone deacetylase inhibitor panobinostat and the immunomodulatory cytokine Interferon-alpha2a can reduce the residual reservoir of HIV-1 infected cells that persist during treatment with currently available antiretroviral drugs.
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.
A single oral dose study in subjects with hepatic impairment and healthy control subjects. Subjects will stay at the clinical facility where interval blood samplings will be obtained and examined for drug effect.
Like most of sub-Saharan Africa, Rwandan youth are the epicenter of the AIDS epidemic, accounting for 40% of new infections. Antiretroviral (ART) adherence is a global health priority, but Rwandan youth are more than twice as likely to be on second line therapy than adults, and with a median population age of 18.7 years old, adherence is essential for Rwanda's future. Resources to provide youth-centered medical and psychosocial care are limited in Rwanda, and young people with HIV face many obstacles to adherence, namely the long-term consequences of genocide, depression, and gender-based violence, as well as logistical issues, negative attitudes, and insufficient parent/caregiver support. Preliminary data underscore the utility of culturally-adapted, trauma-informed cognitive behavioral therapy (TI-CBT) in reducing depression and traumatic distress among youth and adults in Rwanda. This project proposes a 2-arm randomized controlled trial (RCT) to test and compare the efficacy of adherence-enhanced Trauma Informed Cognitive Behavioral Therapy (i.e., TI-CBTe) to usual care in increasing ART adherence among Rwandan youth from two clinics caring for the largest number of youth with HIV in Rwanda. This proposal answers a compelling need for innovative programs to increase ART adherence among HIV+ youth. If effective, the study will build Rwanda's capacity to provide much needed services; and, involvement by the Rwanda Biomedical Center will ensure wide dissemination.
