Filter by:Despite the implementation of a national strategy to prevent the transmission of the human immunodeficiency virus (HIV) combining prevention campaigns, condom use, early detection of HIV infections and recommendations for treatment as soon as possible, the number of new HIV-infected patients per year in France does not decrease. New HIV prevention strategies are therefore clearly needed. Since 2009, several studies have shown that tenofovir disoproxil fumarate and emtricitabine (TDF/FTC), an antiretroviral therapy combining two nucleoside reverse transcriptase inhibitors used for the treatment of patients seropositive for HIV, has preventive activity on HIV transmission. These results enabled the TDF/FTC to obtain in France an extension of the marketing authorization in March 2017 for preexposure prophylaxis (PrEP) of HIV transmission among patients at high risk of contamination. Since the approval, many studies around the world investigate the use of PrEP in routine practice, highlighting its effectiveness in real life. These studies describe the population of patients who benefit from PrEP in order to adapt their multidisciplinary care but also track the transmission of other sexually transmitted infections to prevent their emergence, given the observed decline in condom use. However, these studies are limited to big cities while PrEP is accessible in all territories. The Rhône-Alpes region is one of the three French regions that has been the most involved in the implementation of PrEP, one year after the FTC/TDF approval in France. Given the geographical position of the investigators, both in province and close to Switzerland, where the FTC/TDF is not authorized for PrEP, and the non-university nature of five of the six involved hospitals, the investigators would like to determine the profile of patients consulting in this region to benefit from PrEP. This analysis will also determine if the population at risk of the "Alpine Arc" region is similar to that observed in the other cohorts in order to adapt patient care.
A randomized three arm control trial to examine the efficacy of two distinct apps (LYNX and MyChoices) developed for young men who have sex with men (YMSM) compared to standard of care (SOC) information about HIV testing and PrEP (Pre-Exposure Prophylaxis).
This is a formative study, designed to provide information required to tailor Life-Steps for Pre-Exposure Prophylaxis (PrEP), an evidence-based cognitive behavioral adherence intervention, to enhance PrEP uptake and adherence in high risk young men who have sex with men (YMSM) and young transgender women who have sex with men (YTWSM). Life-Steps for Pre-exposure prophylaxis (PrEP) is a manualized modular adherence intervention based on principles of cognitive-behavioral therapy (CBT), that allows for recipients of the intervention to focus on the greatest challenges that they perceive in maintaining optimal adherence to PrEP.
The researchers are working with a technology company, AiCure, to develop a smartphone app, DOT Diary, which combines two drug adherence strategies. DOT Diary reminds people when it is time to take their medication, and uses motion-sensing technology to visually and automatically confirm the pill was swallowed. The goal of this study is to assess the impact of the app on adherence to HIV pre-exposure prophylaxis (PrEP) for the prevention of HIV.
The premise for the study is that a tailored approach for rural young men who have sex with men (YMSM), addressing known barriers of transportation, access to providers, and privacy, is most likely to yield high levels of Pre-exposure Prophylaxis (PrEP) initiation and persistence in care.
Pre-exposure prophylaxis (PrEP) is a daily pill that greatly reduces the risk of transmission of human immunodeficiency virus (HIV), however the barriers to PrEP use for women are understudied and PrEP is underutilized by women. Partnering with the DC Department of Health and the DC Center for AIDS Research (DC-CFAR), the overarching goals are (1) to identify and populate the PrEP cascade for women, (2) to provide a blueprint for family planning providers to integrate HIV prevention into their practices and target evidence-based interventions to the women at highest risk for HIV in their communities, and (3) to evaluate the cost-effectiveness of this intervention. The overarching hypotheses are that (1) the timeline and roadmap to PrEP adoption and the PrEP cascade will be different for cis-gender women than that described for men who have sex with men (MSM) and transgender women, (2) women seeking family planning services will be eligible for and interested in PrEP and family planning providers are ideally situated to provide this care, and (3) provision of PrEP in the family planning setting will be cost-effective. This research proposes to evaluate (1) PrEP cascade of events for women (eligibility for PrEP, acceptability/interest in PrEP, access/linkage to a PrEP program, initiation of PrEP, retention, and adherence to PrEP) and (2) the integration of universal screening for PrEP and PrEP provision into a women's family planning clinic. This research will allow for targeted evidence-based interventions to reach women at high-risk for HIV and will provide a blueprint for the implementation of PrEP services in the family planning setting nationally.
The specific aims of this study are: 1. To explore perceived facilitators and barriers to initiating and adhering to HIV PRE-EXPOSURE PROPHYLAXIS (PrEP) among at-risk YOUNG MEN WHO HAVE SEX WITH MEN (YMSM). 2. To assess the acceptability and feasibility of a culturally-tailored peer navigator program to optimize adherence to PrEP among YMSM.
The researchers are working with a technology company, AiCure, to develop a smartphone app, DOT Diary, which combines two drug adherence strategies. DOT Diary reminds people when it is time to take their medication, and uses motion-sensing technology to visually and automatically confirm the pill was swallowed. The goal of this study is to understand people's experiences using this new app while taking HIV pre-exposure prophylaxis (PrEP) for the prevention of HIV.
This pilot study will assess the feasibility and acceptability of a peer outreach and navigation intervention designed to increase access and promote HIV pre-exposure prophylaxis (PrEP) uptake among women at high risk for HIV.
The study will be a randomized, open-label, cross-over clinical pharmacokinetic trial to investigate a strategy for probenecid "boosting" in the setting of tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) for HIV pre-exposure prophylaxis (PrEP). The study will be conducted at the Indiana University Clinical Research Center. All samples will be processed and the amount of tenofovir/FTC in plasma, blood, and urine, and tenofovir diphosphate and emtricitabine in peripheral blood mononuclear cells will be determined using validated analytical methods developed by the investigators at the University of Colorado. Probenecid plasma and urine concentrations will also be measured using an in-house assay. Following completion of the study, the secondary aim will be accomplished via analysis of selected samples collected at baseline and following treatment. Those selected samples will be assessed for urinary markers of proximal tubulopathy (urine total protein, albumin, creatinine, phosphorus, retinol binding protein, and beta-2-microglobulin) and serum alkaline phosphatase, osteocalcin, procollagen type 1 N propeptide, cystatin C, and creatinine to determine if the probenecid boosting strategy does indeed lead to less potential renal and bone toxicity.
