Active clinical trials for "HIV Infections"

This study will evaluate the efficacy of Stribild® (elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (EVG/COBI/FTC/TDF)) single-tablet regimen (STR) after switching from a regimen consisting of raltegravir plus Truvada® (FTC/TDF) at baseline in maintaining HIV-1 RNA < 50 copies/mL at Week 12 in virologically suppressed, HIV-1 infected adults. This study will also evaluate the safety, tolerability, and efficacy of Stribild over 24 and 48 weeks of treatment.

The purpose of this study is to determine the correct dose of Vitamin D to give to prevent HIV related complications.

The purpose of this study is to evaluate the first web-based cessation program developed expressly for people living with HIV who smoke tobacco. Main study goals are (1) to evaluate the website's feasibility (i.e., recruitment, adherence, retention, and satisfaction) and (2) to complete a prospective, randomized controlled trial comparing the efficacy of the online program to standard care with a primary outcome of 3 month point-prevalence abstinence.

The purpose of this study is to evaluate the effectiveness and safety of telaprevir, given with pegylated-interferon-alfa-2a (Peg-IFN-alfa-2a) and ribavirin (RBV) in the treatment of hepatitis C in patients infected with both chronic hepatitis C virus (HCV-1) and human immunodeficiency virus (HIV-1).

This is an open-label, single-sequence, two-way drug interaction study to investigate the PK, safety and tolerability of GSK3640254 and DTG when administered alone or in combination in healthy subjects. Treatment of human immunodeficiency virus (HIV) infection frequently involves combination therapy. Data from this study will contribute to dosing recommendations when GSK3640254 and DTG are given in combination. The study will consist of a Screening period and 3 sequential treatment periods. Subjects will be administered DTG 50 milligrams (mg) once daily (QD) in Period 1 followed by GSK3640254 200 mg QD in Period 2. There will be a washout period of 4 days between Periods 1 and 2. In Period 3, subjects will be co-administered DTG 50 mg QD and GSK3640254 200 mg QD. The total duration of the study will be approximately 55 days, including Screening.

The persistence of an aberrant state of immune activation and inflammation (pIA) may contribute to the emergence of serious non-AIDS events which carry a higher morbimortality in HIV-infected patients. Although combined antiretroviral treatment (cART) reduces both cellular and soluble activation markers, it fails to completely control pIA despite consistent plasma viral load suppression. One of the mechanisms involved in pIA is may be an incomplete suppression of viral replication not reflected by plasma viral load, which only reflects a balance between viral replication and clearance of HIV-RNA. In addition, low-level viremia detected in most HIV-1-infected patients despite years on cART. Unintegrated 2-LTR HIV-DNA, and cellular associated HIV-RNAs, as products of active integrated DNA transcription, support this issue. Furthermore, the key rationales behind simplifying cART are a reduction of toxicities, lower risk of resistance mutations in case of virological failure and saving costs. One of these simplification strategies is a dual therapy which, based on the data up to date and in our clinical experience, has similar virological efficacy than cART. However, it is unknown if this strategy could increase the persistent HIV-1 replication and, therefore, pIA. The CD4+/CD8+ T cell ratio as a marker of immune recovery, the changes in T cell immune activation, senescence, exhaustion and apoptosis, and the cellular associated HIV-DNA and -RNA would answer the question if simplification to dual therapy would provide less control of residual HIV replication and, therefore, a detriment on pIA compared to triple therapy and, therefore, would worsen the patients' long-term prognosis.

This is a phase 2, open-label efficacy study of VGX-3100 administered by intramuscular (IM) injection followed by electroporation (EP) in adult men and women who are human immunodeficiency virus (HIV) negative with histologically confirmed anal or anal/peri-anal high-grade squamous intraepithelial lesion (HSIL) associated with human papilloma virus (HPV)-16 and/or HPV-18. Approximately 24 participants will receive at least 3 doses of VGX-3100.

A randomized trial to test the feasibility and acceptability of an intervention to improve retention in HIV primary care in HIV-infected Hispanic immigrants compared to a "treatment as usual" condition. We will measure feasibility, acceptability, study retention, and effect sizes of outcomes in order to inform a larger trial. The intervention design is based on qualitative research with HIV-infected Hispanic immigrants and their HIV providers. The intervention will be led by a Spanish-speaking community health worker trained in HIV health promotion.

A phase IV, multicentre, randomised, open-label, pilot clinical trial designed to evaluate HIV-infected, aviremic patients who receive treatment with the combination of DTG/3TC/ABC and who have neuropsychiatric adverse effects that, in the opinion of the investigators, may be related to taking DTG/3TC/ABC, if they improve after switching antiretroviral therapy to the combination of ELV/COBI/FTC/TAF.

Many patients on Highly Active Antiretroviral Therapy (HAART) are able to achieve a sustained response with viral loads becoming undetectable and staying undetectable, but do not have an increase in their CD4 counts to levels greater than 500. Adding maraviroc to the treatment regimen of these patients may result in an increase in their CD4 counts. As the patient would be continuing their prior regimen, they will likely continue with full control of viral replication.
