Filter by:This is a pilot facility-based direct-to-pharmacy PrEP refill delivery to streamline care pathway in Kenyan public health HIV facilities implementing PrEP. Data on up to 500 PrEP users will be evaluated to understand delivery efficiency and in-depth interview with users and delivery key informants will be conducted to identify barriers and facilitators of implementation.
DREAM-02 is a phase 1, open label study to evaluate different sequences of tap water douching and simulated receptive anal intercourse (sRAI) in the presence of a tenofovir douche designed to confer protection from Human Immunodeficiency Virus (HIV) acquisition. DREAM-02 will assess the safety and pharmacokinetics (PK) of different sequences of administration of tap water (H2O) and rectal tenofovir (TFV) douches to more accurately represent the community practice of commonly using cleansing douches prior to RAI, and occasionally after RAI. DREAM-02 results are essential to gain understanding of Tenofovir diphosphate (TFV-DP) concentrations at various anatomic distances in the colon, and how those concentrations may be modified by sRAI, seminal fluid, and sequence of cleansing tap water douches.
This research study will determine how well two female condoms perform when used during sex. One of these condoms (FC2) is already commercially available in South Africa. The other female condom, "Wondaleaf Condom" is a new female condom. Participants will use both condoms. The study aims to determine how well these condoms work comparatively. Study visits include a screening/enrolment visit and 2 follow up visits.
Truvada (Emtricitabine or FTC and tenofovir disoproxil fumarate or TDF) has been approved for HIV prevention since 2012. Drug concentrations after receipt of oral Truvada for HIV Pre Exposure Prophylaxis (or PrEP) appeared to be lower in transgender women compared to Men who Have Sex with Men (MSM) in the iPrEx study, the landmark study of PrEP for HIV prevention. Concentrations were especially low among transgender women (TGW) reporting use of feminizing hormones. Reasons for the lower drug concentrations may be behavioral or biomedical, or a combination of both. While there are no systemic drug-drug interactions between TDF and oral contraception, there are known interactions involving these classes of medications with drug transporters that could affect drug concentrations in target tissues. Drug-drug interactions with natural estrogens and anti-androgenic agents used for gender affirming hormone therapy among transgender women have not been studied, neither have interactions between emtricitabine and female hormones. Concerns about the impact of PrEP on gender affirming hormone therapy is the main barrier for uptake of PrEP among transgender women. In addition, very little is known about TDF/FTC pharmacokinetics in transgender men using testosterone hormonal therapy. Drug-drug interactions with masculinizing hormones have never been properly investigated as trans gender men have not been formally involved in PrEP clinical trials or demonstrations projects.This small study will assess pharmacokinetic drug-drug interactions between tenofovir disoproxil fumarate/emtricitabine and cross-sex hormone therapy. The I-BrEATHe study is a substudy of the Triumph study, a culturally-relevant community-led PrEP demonstration project in transgender communities. The I- BrEATHe pharmacokinetic substudy will provide Truvada daily using directly observed therapy in 24 transgender women and 24 transgender men over a one month period, and will measure drug and hormone therapy levels in blood collected from participants.
The project seeks to determine whether implementing a multilevel, woman-focused intervention, the Young Women's Health CoOp (YWHC), for pre-exposure prophylaxis (PrEP) readiness, uptake, and adherence is a viable complement to the HIV prevention plan for the Government of South Africa. Specifically, this project aims to: increase uptake, of sexual and reproductive health (SRH) services and readiness and uptake of PrEP among adolescent girls and young women (AGYW) aged 16 to 24 who engage in high-risk sexual behaviors; and reduce their barriers to accessing SRH services by addressing and reducing stigma and discrimination (S&D) in clinics.
MTN-045 is a cross-sectional study that will utilize questionnaires, including Discrete-Choice Experiments (DCE) and joint decision tasks, to assess couples' preferences related to dual purpose prevention (DPP) products that could be used to prevent unintended pregnancies and HIV infection. Post-survey explanatory in-depth interviews (IDIs) will be conducted with a subset of participants to explore DPP product-related decisions..
Nationally, the HIV case rate among black/ African American (AA) women is nearly 20 times higher than in white women; for Hispanic/Latino women it is 4.5 times higher. Moreover, according to findings in the HIV Prevention Trials Network (HPTN) Study 064 (The Women's HIV SeroIncidence Study), HIV incidence among women who live in communities with high HIV prevalence and poverty is about 6 times higher than for black/AA women. South Florida's new HIV diagnoses are now triple the national average due to rates in Miami-Dade and Broward counties in its AA, Latino and Haitian communities. Black women follow black men who have sex with men (MSM) as the most crisis-ridden of the communities in South Florida, the state as a whole, the South, and the U.S. Women overall have been at a disadvantage in the HIV epidemic due to gender differences and norms that shape biological, social and economic vulnerability. Racial and ethnic disparities magnify the risk. Co-factors such as alcohol and other drug (AOD) use intersect and reinforce other comorbidities. Living in a high prevalence area significantly hardens the risk and makes it tougher to overcome. Options to help women stay HIV negative have been limited, and the absence of practical female-controlled prevention strategies and relative dependence on cooperative use of the male condom continue to keep women's HIV vulnerability high. This obstacle shifted several years ago with FDA approval and Centers for Disease Control and Prevention's (CDC) endorsement of oral pre-exposure prophylaxis (PrEP). However, women do not know about PrEP. Despite FDA approval in 2012, followed by expansions in recommended use from the CDC and World Health Organization (WHO), the majority of women in the U.S. are not aware of oral PrEP as an HIV prevention strategy that applies to them. This study utilizes community-based participatory research (CBPR) to develop an intervention program that will promote optimal PrEP utilization among women of color in South Florida. The overall goal is to determine how best to target and improve PrEP utilization among women of color with substantial risks for HIV, including alcohol use.
DREAM-03 is an early phase-1, open label study to compare the safety, pharmacokinetics (PK), pharmacodynamics (PD), and acceptability of 3 sequences of tenofovir (TFV) and non-medicated douches. The overall goal is to inform the design of an extended safety study of an on-demand and behaviorally congruent TFV douche to confer protection from HIV acquisition in an outpatient pre-RAI context.
The purpose of this study is to evaluate the acceptability and performance of a directly assisted oral HIV self-testing (HIVST) program in a youth population aged 14-24 in Nigeria. The study is oral HIV self-testing (HIVST) program in a youth population aged 14-24 in Nigeria. The study is focused on assessing young people's ability to correctly perform the test.
In this mixed-methods research study, the study team will offer comprehensive safer conception services to 150 HIV-uninfected women reporting an HIV-infected or high-risk partner and personal or partner plans for pregnancy in rural Uganda to evaluate prevalence and determinants of uptake and adherence (tenofovir plasma concentration >40ng/mL, opening pill device to take >80% of dispensed pills) to PrEP and other safer conceptions strategies among Ugandan women exposed to HIV.
