NCT ID: NCT03468582 Recruiting - Clinical trials for Human Immunodeficiency Virus

123I Radiolabeled 3BNC117

Start date: February 8, 2018
Phase: Early Phase 1
Study type: Interventional

The conventional way to control HIV infection is the usage of a drug cocktail capable of suppressing the viral replication cycle, commonly known as antiretroviral therapy (ART). Despite effective ART it is not possible to eradicate HIV. The virus hides in particular cells to form the latent HIV-reservoir.[1-9] Studies that emphasise on revealing hidden reservoirs would aid in designing novel therapeutic strategies for controlling HIV infection. Molecular imaging by SPECT/CT has the potential to reveal hidden reservoirs of HIV virus that are not eliminated by currently used drugs capable of suppressing and thereby controlling the viral replication cycle in HIV infected patients. New approaches, necessary to prevent and treat HIV-1 infection, are gradually emerging. A new generation of highly potent broadly neutralizing antibodies (bN/Abs) may represent a promising approach to combating HIV-1 infection.[10] The broadly neutralizing antibody 3BNC117 antibody that can mimic human CD4 binding targeted against the HIV gp120 envelope protein has been tested in various clinical trials.[11-14] It has found to be safe and effective in reducing viraemia and to improve host humoral responses in HIV-1 infected individuals, and to have effect on viral rebound in patients who are kept off antiretroviral treatment briefly for experimental purpose. Imaging of simian immunodeficiency virus (SIV) infection by PET/CT has been successfully performed in nonhuman primates with a 64Cu-labeled SIV gp120-specific antibody called 7D3.[15] This study aims to use a similar approach in human with the 3BNC117 antibody. The 3BNC117 antibody has been successfully radiolabeled with iodine 123. The half-life of this radioisotope is appropriate for antibody imaging in nuclear medicine. Radiolabeled 123I 3BNC117 was shown to keep a good immunoreactivity for gp120. By using state of the art SPECT scanner a semi-quantitative image will be obtained. In addition, the absence of any chelator and the well known use of iodine-123 in clinic make it suitable for human intervention. No HIV imaging in human has been achieved yet, which is however fundamental to understand some key steps in the pathogenesis of HIV-induced immunodeficiency. This research opens promising opportunities for drug and vaccine development. Indeed, identification of virus reservoirs in treated patients would facilitate the development of strategies for eradicating these reservoirs or for extending latency period.

Prevalence of Chronic Kidney Disease (CKD) and Risk Factors in Sub-Saharan Africa

Start date: December 8, 2010
Phase: N/A
Study type: Observational

Prospective cross-sectional study at the outpatient clinic (OPC) of the Bagamoyo District Hospital (BDH) in Tanzania. Assessment of basic epidemiological data (Point prevalence and risk factors) on CKD with simple clinical, laboratory tests and the patients history. After informed consent blood samples are taken for complete blood count, serum creatinine, HbA1c, HIV-Screening, and urine samples for dipstick, urine sediment, and albumin-creatinine ratio. Further, office blood pressure, weight and height are taken. Further, patients history are asked by a questionnaire (i.e.history of infectious and cardiovascular diseases and basic demographic data: i.e. sex, age). CKD is defined as the presence of either impaired kidney function and/or albuminuria based on a one-time measurement. Primary outcome of the study are prevalence rates of CKD and the impact of non-communicable and communicable disorders on CKD.

NCT ID: NCT03449706 Recruiting - HIV Clinical Trials

Accurate Staging of Immuno-virological Dynamics During Acute HIV Infection

Start date: September 1, 2017
Phase: N/A
Study type: Observational

In this prospective longitudinal study we aim to assess how immunologic and viral aspects of the human immunodeficiency virus (HIV) viral reservoir, established during early HIV infection and responsible for viral rebound at treatment interruption, evolve in individuals who start combination anti-retroviral therapy (cART) during acute seroconversion. Recently infected patients will be selected based on Fiebig staging for an in depth sampling protocol at different timepoints during a 2 year follow up period. Colonbiopsies, lymphnode resection, lumbar puncture, leucapheresis and repeated peripheral venous blood-draws will be performed. Immunological, virological and genome expression analysis will be performed on the gathered samples.

NCT ID: NCT03447873 Recruiting - HIV Infections Clinical Trials

Tripe Versus Dual Antiretroviral Therapy in HIV-infected Patients With Virological Suppression (Tridual)

Start date: June 1, 2017
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT03446573 Recruiting - Clinical trials for Infection, Human Immunodeficiency Virus

Switch Study to Evaluate Dolutegravir Plus Lamivudine in Virologically Suppressed Human Immunodeficiency Virus Type 1 Positive Adults

Start date: January 18, 2018
Phase: Phase 3
Study type: Interventional

The aim of the study is to establish if human immunodeficiency virus type 1 (HIV-1) infected adult participants with current virologic suppression on a ≥3-drug tenofovir alafenamide (TAF) based regimen (TBR) remain suppressed upon switching to a two-drug regimen of dolutegravir (DTG) 50 milligram (mg) + lamivudine (3TC) 300 mg. This study will also provide important information regarding the safety and participant satisfaction with this two-drug regimen. The primary objective of this trial is to demonstrate the non-inferior antiviral activity of switching to DTG + 3TC once daily compared to continuation of TBR over 48 weeks in HIV-1 infected, ART-experienced, virologically suppressed participants. This study also will characterize the long-term antiviral activity, tolerability and safety of DTG + 3TC through Week 100. This will be a 100-week, Phase III, randomized, open-label, active-controlled, multicenter, parallel-group study. The study will include a screening phase (up to 28 days), a randomized early switch phase (Day 1 up to Week 52), a randomized late switch phase (Week 52 up to Week 100), and a continuation phase (post Week 100). Approximately 550 HIV-1 infected adults on stable TBR will be randomized 1:1 to switch to DTG + 3TC once daily for up to 100 weeks, or to continue their TBR for 52 weeks, at which time and if HIV-1 ribonucleic acid (RNA) <50 copies per milliliter (c/mL) at Week 48, these participants will switch to DTG + 3TC up to Week 100.
