Active clinical trials for "HIV Infections"

The purpose of the study is to evaluate the efficacy and safety of autologous CD34+ cells that stably express multiplexed shRNA to treat HIV infection.

This trial evaluates options for second-line antiretroviral therapy in patients failing on a non-nucleoside reverse transcriptase inhibitor (NNRTI) and tenofovir (TDF)-based first-line regimen in the setting of the public health approach in sub-Saharan Africa (with assumed substantial nucleoside reverse transcriptase inhibitor (NRTI) cross-resistance). The trial tests two hypotheses. Firstly that a regimen of dolutegravir (DTG) with two NRTIs is non-inferior to a regimen of ritonavir-boosted darunavir (DRV/r) with two NRTIs. Secondly that continuing an NRTI regimen of TDF and lamivudine (3TC) is non-inferior to switching to zidovudine (ZDV) and 3TC. The trial is a parallel group, open-label, multi-centre, factorial (2X2) randomised, controlled trial. Patients will be randomised to either DTG or DRV/r with a second randomisation to ZDV and 3TC or TDF and 3TC. Treatment efficacy will be monitored by testing viral load (VL). Analyses will compare DRV/r with DTG; and ZDV/3TC with TDF/3TC by intention to treat analysis on the primary outcome parameter of plasma VL below 400 copies/ml at 48 weeks. Trial follow-up will continue to 96 weeks.

Through a multi-center large-sample non-randomized controlled study, the effect of voriconazole, amphotericin B sequential itraconazole therapy on Talaromyces in Human Immunodeficiency Virus（HIV）negative hosts were compared to clarify whether the two therapies were equivalent; A comprehensive efficacy evaluation system and standard treatment program was established to provide a basis for standardized treatment of Talaromyces in Human Immunodeficiency Virus negative hosts.The observational indicators included: 2-week all-cause mortality; 24-week all-cause mortality; clinical improvement time; level of decrease of fungus in the blood culture medium two weeks before treatment; recurrence; appearance of adverse drug reaction at the level 3 and above. Dynamically monitor the immune cells and factors like anti-Interferon-γ autoantibodies, Interferon-γ, Th1/Th2, and Th17/Treg in the HIV-negative Talaromyces host microenvironment, and observe the host's immune status and its change. 3. study the effect of absence of Interferon-γ and Interferon-γ Receptor (IFN-γR）on the activation and function of anti-Interferon-γ autoantibodies, Th1/Th2, and Th17/Treg by establishing a Talaromyces mouse model that knocks out the Interferon-γ and IFN-γR gene and a IFN-γ silenced cell model; Study the effect of anti-IFN-γ autoantibody on the activation and function of IFN-γ、Th1/Th2、Th17/Treg by increasing its titer in vitro and vivo; determine by which path the anti-IFN-γ autoantibody of HIV-negative host influences its immune regulation mechanism; finally, the intervention effect of IFN-γ on high titer anti-IFN-γ autoantibodies is studied, providing a new idea for immunotargeted therapy.

Multicenter, randomized, open label pilot clinical trial with two parallel arms aimed to compare the efficacy of Raltegravir (RAL) 1200mg QD vs Darunavir/Cobicistat (DRV-cb) 800-150mg QD both in combination with alafenamide/emtricitabine (TAF/FTC) in patients with Human Inmunodefficiency Virus (HIV) infection and CD4<200 cells/microL

This project is designed to 1) develop a PrEP implementation plan for a general adolescent clinic. Investigators will develop a replicable implementation plan for providing PrEP to adolescents in a primary care setting; and 2) Determine the acceptability and preliminary effectiveness of a telehealth intervention to promote adherence in adolescents.

Virological failure is a complication of treatment in patients with HIV, and it can be as high as 42% to first line treatment or around 18% in second line treatment. The reasons behind this phenomenon are several, including adherence to treatment (self-patient) or those related to the drugs (kinetics, interactions) and the virus itself (resistance patterns). People living with HIV needs treatment for all their lives, another factor to facilitate virus resistance and poor adherence to treatment. For that reason, it is necessary to look for additional therapeutic options to minimize this problem, and the use of immunomodulatory drugs is an interesting topic now. Among those drugs, isoprinosine hs been reported not only improve the immune response, it also has the capability to inhibit the replication of RNA virus. Then, we propose an open label clinical trial to evaluate the effect of isoprinosine in HIV patients with a virological load between 50 and 200 copies/ml.

Long-term side effects of antiretrovirals (ART) have led to the introduction in clinical practice of NRTI-sparing regimens as double- or mono- therapy and their use is now recommended in specific populations by International Guidelines. Indeed, based on the monitoring of surrogate markers of ART efficacy, most of these unconventional regimens, when used in switch studies, have shown to have a non-inferior virological efficacy and a good CD4 recovery compared to standard triple drug-based therapy. At present, the best marker to evaluate the risk of developing of non-AIDS related events has not been determined. Interestingly, the analysis of the data of the investigator's and others cohorts have shown that, in contrast with recent data from ART-CC collaboration, a low CD4/CD8 ratio is a predictor of non-AIDS related events independently from CD4 cell count, while other studies have shown an association of this marker with non-AIDS defining cancers or, more recently, with pulmonary emphysema. Aim of the present study is to compare CD8 and CD4/CD8 slopes in patients switching with an undetectable viral load to the 2 regimens which will be more frequently used in clinical practice: i.e B/F/TAF and dolutegravir + lamivudine. Indeed, B/F/TAF is already a recommended regimen in all guidelines while dolutegravir + lamivudine is widely used in clinical practice.

A randomized, placebo-controlled, once weekly dose for four weeks, double blind study in Healthy HIV-Uninfected Volunteers. Each of 3 consequent groups (120 mg, 200 mg and 280mg) enrolls 6 active and 2 placebo subjects.

Cryptococcal meningitis (CM) is one of the leading opportunistic infections and one of the most common causes of death in AIDS patients. Amphotericin B (AmB) is the corner stone in CM treatment. The effect of AmB was dose-dependent. Recent retrospective study indicated that longer duration rather than higher dose of AmB is necessary to reduce the mortality of CM. We aimed to explore the efficacy and safety of small dose but longer duration of AmB for the treatment of HIV-associated CM.

This study seeks to measure the costs associated with HIV prevention service delivery to female sex workers (FSW) in Nigeria, as well as examine the relationship between management practices at the community-based organizations (CBOs) and costs. To complete these goals, the study will collect both retrospective and prospective data from CBOs and from centralized information from study partners (Society for Family Health, SFH). In the prospective section of the study, CBOs will be sampled and assigned to either treatment or control groups. Data collected at the CBOs will be aggregated by the CBO managers, and those in the treatment group will receive feedback on their performance on a monthly basis. Those in the treatment group will additionally receive a management training to guide their management practices. Researchers hypothesize that there will be improvements in management indicators and therefore decreases in costs at CBOs in the treatment group. Results will be disseminated to local, national, and international stakeholders.
