Active clinical trials for "HIV Infections"

This study will evaluate whether oral islatravir (ISL) is effective in preventing Human Immunodeficiency Virus Type 1 (HIV-1) infection in women at high-risk for HIV-1 infection. The study will compare oral ISL taken once a month with standard-of-care medication for prevention of HIV-1 infection, emtricitabine/tenofovir disoproxil (FTC/TDF), taken once per day. The primary hypothesis is that oral ISL is more effective than FTC/TDF at reducing the incidence rate per year of confirmed HIV-1 infections.

The objective of this proposal is to conduct a pilot test of a program aimed at training traditional healers to conduct HIV testing and implementing HIV testing among people living in Bushbuckridge, South Africa. Pilot Healer-initiated HIV testing uptake and linkage to prevention services. Trust in allopathic health care and HIV stigma will be measured among participants at study enrollment and at month seven. Hypothesis: Healer-initiated HIV counseling and testing (HICT) will increase trust in allopathic health care and reduce HIV stigma.

The purpose of the study is to evaluate the safety, tolerability, and immunogenicity of polyvalent env (A,B,C,A/E)/gag (C) DNA and gp120 (A,B,C,A/E) protein vaccines (PDPHV201401) co-administered together with or without adjuvant in repeated doses in healthy, HIV-uninfected adults

Scale-up of HIV preexposure prophylaxis (PrEP) is a key strategy of the federal initiative to end the HIV epidemic. However, healthcare providers lack tools to identify patients who are at increased risk for HIV infection and thus likely to benefit from PrEP. This pilot study will test the hypothesis that an electronic health record (EHR)-based clinical decision support system that incorporates an HIV risk prediction model can help providers identify patients at increased risk for HIV infection and improve PrEP prescribing in safety-net community health centers. The clinical decision support system will be implemented in the EHR at 2-3intervention clinics, while 2 control clinics will receive standard of care. The primary outcome is PrEP prescriptions. Other key metrics of PrEP-related care to be assessed include medication persistence, adherence to monitoring guidelines for PrEP, and rates of HIV/STI testing and diagnoses. The expected outcome is the foundation for a large-scale cluster randomized trial to test whether EHR-based clinical decision support tools for PrEP can improve PrEP prescribing and prevent new HIV infections in a national network of community health centers.

The purpose of this study is to evaluate the safety and immunogenicity of HIV-1 vaccines based on chimpanzee serotypes of adenovirus expressing clade C gp140 and a CH505TF gp120 protein boost in healthy, HIV- uninfected adult participants.

The goal of this study is to understand the interaction between HIV and the host at the earliest stages when HIV medications are paused. Volunteers with HIV will interrupt antiretroviral therapy (ART) and then have intensive studies preformed two to three times per week. Most will resume therapy within three weeks, even if the virus does not rebound during this time.

mHealth solutions designed to support affordable human resources for health, such as community health workers (CHWs), offer the opportunity to reimagine a patient-centered, system-level solution that may radically change care models in low resource settings. The 'leap' of m-health is most potent and practical in settings where desktop-based infrastructure is lacking and hard-wired internet connectivity is unavailable. Investigators have demonstrated the feasibility of mHealth and human resource solutions in South Africa and shown marked improvements in screening, linkage and treatment initiation as well as supporting patient adherence through video DOT (vDOT) and early identification of treatment related toxicity. Investigators' strategies have evaluated solutions for individual cascade steps through TB and HIV smartphone and tablet-based m-health applications implemented by a CHW. This study combines these individual cascade step approaches into an innovative TB/HIV cascade intervention study entitled, "Leveraging mHealth to enable and adapt community health worker strategies to improve TB/HIV patient outcomes in South Africa (LEAP-TB-SA) Trial."

The project aims to assess the level of oxidative stress biomarkers in HIV patients on effective antiretroviral treatment in correlation with other therapeutic, clinical, and viro- immunological parameters. The analysis aims to better characterize the patient on treatment through an innovative approach based on two specific tests for complementary assessment of total oxidant and anti-oxidant plasma capacity.

This study will investigate the use of a next-generation Reader as part of a digital pill system (DPS; ID-Cap System) to measure adherence to both antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) in people living with HIV (PLWH) and HIV-negative individuals, respectively. During the first (non-human subjects) component of this study, we developed a wrist-borne Reader according to design specifications and preferences shared by DPS users from our previous studies. Early bench testing by etectRx (manufacturer of the ID-Cap System) demonstrated that the wrist-borne version of the Reader acquires signal from the digital pill. This study will therefore evaluate the usability of and user response to a wrist-borne Reader component of the DPS among PLWH on ART and HIV-negative individuals on PrEP.
