Filter by:Tragically, HIV infections among Black sexual minority men (BSMM) in the U.S. persist. Despite the availability of pre-exposure prophylaxis (PrEP) for HIV prevention, effective uptake among BSMM remains low. It is imperative to support PrEP initiation among this group. The proposed multi-component interventional study is designed to increase HIV risk perceptions and subsequent PrEP initiation through the use of our team's existing mobile application called PrEPme and a peer change agent (PCA) to record and review sexual risk behaviors and subsequent PrEP interest. Few have studied whether reviewing sexual diaries with a PCA increases HIV risk perceptions and PrEP initiation among BSMM. This strategy will allow BSMM who are not using PrEP to record their sexual behaviors using a PrEPme-based diary, review their sexual histories with a PCA, and assess PrEP interest. The PCA will be trained in motivational interviewing techniques to facilitate discussions. The PCA will provide HIV prevention education, sexual risk evaluation, and PrEP navigation. BSMM who become interested in initiating PrEP will be referred to our team's ongoing PrEP tele-medicine study (PI: Jason Farley, co-investigator) or other PrEP care services in the greater Baltimore area. The proposed intervention targets a high priority population in HIV prevention and mitigates structural barriers to PrEP uptake such as perceived judgement, stigma, and discrimination from clinical providers.
Transgender women (trans women; assigned male sex at birth but identify as female) are at high risk for HIV infection, and are an important, under-researched population in sub-Saharan Africa. Trans women have a 13 times greater risk of acquiring HIV than adults aged 15-49 years in the general population, and in Africa, trans women have nearly twice the HIV prevalence (25%) of men who have sex with men [MSM] (14%). Oral pre-exposure prophylaxis (PrEP) is an effective prevention tool that could change the trajectory of the HIV epidemic among the 25 million trans women globally, yet its use has been suboptimal in this vulnerable population. Same-day PrEP initiation is feasible and acceptable and improves retention in PrEP care in resource-rich settings. Same-day initiation of emtricitabine/tenofovir alafenamide (F/TAF), a new PrEP regimen, has not to our knowledge previously been evaluated as PrEP in African trans women. F/TAF is potentially more efficacious and safer than emtricitabine/tenofovir disoproxil fumarate (F/TDF) as shown in the recent DISCOVER trial. However, concerns about drug-drug interactions between feminizing hormonal therapy (FHT) and PrEP are a key potential adherence barrier for trans women. While PrEP drugs do not lower FHT levels, FHT decreases plasma TFV and (emtricitabine) FTC levels. Little is known about FHT use among African trans women taking F/TAF or how concerns about F/TAF-FHT interactions may influence PrEP adherence. Moreover, interventions to support PrEP adherence in this population are needed. Feedback about PrEP use has been shown to potentially improve PrEP adherence among MSM but has not been utilized among trans women. Key knowledge gaps include: 1) whether same-day PrEP can be successfully implemented for African trans women, 2) the impact of drug-level feedback on PrEP adherence, and 3) how use of FHT may influence PrEP adherence. To address these questions, this protocol describes a randomized trial to evaluate the feasibility and acceptability of same day initiation of F/TAF PrEP, evaluate impact of drug-level feedback on PrEP adherence and characterize PrEP persistence, and in-depth interviews to explore how self-care interventions for sexual health influence prevention choices among trans women and their sexual partners. This will be the first clinical trial, to our knowledge, to evaluate F/TAF as PrEP for HIV-negative trans women in sub-Saharan Africa.
Despite an increasing armamentarium of behavioral and biomedical HIV prevention methods, since 2010 rates of new infection have remained around 40,000 annually. The demonstrated efficacy and subsequent approval of emtricitabine/tenofovir disoproxil fumarate for pre-exposure prophylaxis (PrEP) for HIV by the FDA in 2012 was thought to represent a turning point that could significantly reduce the number of new infections. Since approval, the promise of PrEP as a transformative intervention has yet to be realized. Despite the implementation of systems for clinical evaluation for and initiation of PrEP by primary care providers, HIV specialists, and STI clinics, numerous barriers to PrEP expansion have been identified, including: 1) patient and provider lack of knowledge, 2) lack of access to medical care among high-risk individuals, 3) provider discomfort and inexperience with screening for risk behaviors, and 4) insurance and affordability. This proposal seeks to expand access to and engagement in PrEP among high risk individuals though an innovative delivery approach in the Emergency Department (ED) while addressing these four barriers.
Transgender women (TGW) are at high risk for HIV infection, and are an important, under-researched population in sub-Saharan Africa. Globally, HIV acquisition risk among TGW is 13 times higher than other adults aged 15-49 years. In Uganda, HIV prevalence among TGW is 22% compared to 5.9% in the general population. Encouraging use of self-controlled HIV prevention tools - specifically, HIV self-testing (HIVST), STI self-sampling (STISS) and antiretroviral pre-exposure prophylaxis (PrEP) - to those testing HIV negative could decrease HIV incidence among African TGW. This R34 application proposes formative research and a pilot trial to develop an HIV prevention intervention for African transgender women (TGW). The investigators will evaluate whether peer-delivered combination HIV prevention increases testing uptake and empowers effective prevention decision making in TGW. Peer-led interventions are effective in increasing HIV and STI testing among other hard-to-reach vulnerable populations with high HIV prevalence but low testing coverage and are recommended by the World Health Organization. Exploring peer-delivery approaches to increase coverage of combination HIV prevention interventions is key to addressing research gaps in HIV epidemic control. However, little is known about the effectiveness of peer-delivered combination HIV prevention (HIVST, STISS and PrEP) for African TGW, or the best way to deliver care to this population. Key knowledge gaps include: 1) whether peer delivery increases testing rates and status knowledge, 2) the role of peers in creating demand for repeat testing and PrEP, and 3) how to optimize peer delivery of combination HIV prevention (HIVST, STISS and PrEP). To address these questions, this proposal seeks to conduct formative research to inform implementation of peer-delivered combination HIV prevention for African TGW (Aim 1), implement a pilot cluster randomized trial to evaluate the feasibility, acceptability and preliminary effectiveness of peer delivered combination HIV prevention (Aim 2), and conduct in-depth interviews to explore how peer-delivery of HIVST, STISS and PrEP influences prevention choices among TGW and sexual partners (Aim 3). This will be the first clinical trial, to our knowledge, to evaluate HIV self-testing and STI self-sampling in HIV-uninfected TGW. Pilot data from TGW and their partners will provide unique perspectives to inform HIV prevention delivery. The proposed proof-of-concept evaluation is uniquely positioned to improve prevention uptake for African TGW - a high-risk, marginalized, and underserved population. Rigorous application of mixed methodologies will generate actionable data for policy and programs, and provide a strong foundation for scalable implementation of cutting edge combination HIV prevention interventions for African TGW. The local transgender community is involved in study design, planning and implementation. This project is supported by the Ugandan Ministry of Health.
The investigators aim to 1) speed up access to and delivery of PrEP to young women, and 2) compare interventions to support and maximize the prevention-effective use of PrEP. Specifically, the investigators aim to answer the following two questions: 1) how can the study use existing community-based platforms to identify and deliver PrEP to those in need? and 2) which adherence support interventions are most likely to engender effective use of PrEP? The investigators propose to answer these questions by leveraging existing community-based HIV testing platforms in South Africa and use a mixed methods approach to optimize the PrEP cascade and evaluate a community-based PrEP adherence program for young women.
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.
The investigators will conduct a randomized trial to evaluate whether provision of oral HIV self-test kits (HIVST) to HIV-positive pregnant women to provide to their male partner, increases the proportion of male partners who test and link to HIV care or prevention, compared to invitation letters for fast track testing. Pregnant women who are randomized to the arm with secondary distribution of HIVST to their male partners will be trained in the use and interpretation of HIVST, and given two oral fluid-based HIVST kits to use with or give to their partners, along with information about HIV testing and prevention and care services. The investigators will offer men confirmatory testing regardless of their HIVST result, counseling, and if negative, pre-exposure prophylaxis (PrEP) and if positive, antiretroviral therapy (ART). The investigators will provide counseling to minimize social harms of HIV self-testing, and additional counseling and referral to social support services when social harms occur. This project will address key challenges in PMTCT B+ programs, by evaluating innovative strategies to increase male partner's knowledge of their HIV status, disclosure, and involvement coupled with offering PrEP to HIV-negative men, ART to HIV-positive men, and encouraging post-partum ART continuation and adherence among HIV-positive women.
This is an open label, non-randomized, observational pilot study to evaluate a model of care for treatment of hepatitis C in people with ongoing injection drug use. Participants will be treated with direct-acting antivirals (DAA) as per standard of care and will concomittantly be offered pre-exposure prophylaxis for HIV prevention and buprenorphine for treatment of opioid use disorder when clinically indicated.
This study involves a one-time, web-based quantitative structured self-complete ("web-based") survey for all subjects and a qualitative semi-structured ("qualitative") interview for a selected sub-sample of subjects to evaluate the consent processes in association with research outcomes, specifically early adherence to Pre-exposure Prophylaxis (PrEP) and Human Immunodeficiency Virus (HIV) seroconversion at any point during participation in the ATN 110 or ATN 113 study.
This study will develop and test a novel, smartphone based gaming intervention to improve adherence to medication to prevent HIV (known as Pre-exposure Prophylaxis, PrEP) and to decrease HIV risk behaviors among men who have sex with men (MSM). In the intervention, participants will engage with an immersive app/game on their iPhone. While gaming, participants will gain information about their health, improve motivation for PrEP and medical appointment adherence, and practice healthy behaviors. If the intervention is found to be effective, it can be tested in a larger study and then disseminated to other people taking PrEP.
