139 Clinical Trials for Various Conditions
The primary objective of this R34 proposal is to increase willingness for PrEP initiation and PrEP initiation among Cisgender Black Women (CBW) and increase willingness to prescribe/refer pre-exposure prophylaxis (PrEP) to CBW among healthcare providers (HCPs) in Houston/Harris County, a high priority Ending the HIV Epidemic (EHE) jurisdiction.
The goal of this clinical trial is to learn if two interventions-C4 and C4+3MV-can improve PrEP adherence (taking medication to prevent HIV) among Black men who have sex with men (MSM). The study will also explore the most effective ways to support participants in continuing their PrEP use over time. The main questions it aims to answer are: * Does the C4 program help participants take PrEP more regularly? * Does adding the 3MV intervention to C4 provide additional support for adherence? Researchers will compare two intervention strategies to see if they result in better PrEP adherence: * C4 Intervention: A program focused on individualized care coordination and addressing structural needs. * C4 + 3MV Intervention: A combination of care coordination with additional behavioral change sessions. Participants will: * Participate in PrEP education and counseling sessions. * Have their PrEP use monitored through dried blood spot (DBS) tests. * Complete questionnaires about their experiences and challenges with PrEP. Receive support sessions tailored to address individual barriers to PrEP adherence.
The investigators have previously developed an integrated bio-behavioral intervention to promote PrEP uptake and adherence in cisgender women who are undergoing treatment for trauma-related mental health conditions and who are at a higher risk for HIV. The intervention is delivered within the mental health treatment setting and integrates knowledge, behavioral skills, and motivation to engage in and adhere to PrEP care. The purpose of this study is to assess the preliminary efficacy, feasibility, and acceptability of this intervention. The hypothesis is that, compared to standard treatment, the intervention will be feasible, acceptable, and associated with greater PrEP uptake and adherence.
The goal of this clinical trial is to test an addiction-clinic based behavioral intervention for increasing PrEP uptake and adherence among women who engage in high-risk sexual behaviors and problematic substance use. The main question it aims to answer is: • If the integrated intervention increase PrEP uptake and adherence compared to standard treatment Participants will * receive provision of PrEP information through 4 counseling sessions * prevention navigation * receive nurse practitioner prescribed PrEP in an addiction treatment setting Researchers will compare intervention group with standard treatment to see if the integrated intervention help increase PrEP uptake and adherence
During the initial encounter, the nurses will complete program enrollment forms (consents and disclosures as approved by IRB), medical history, and risk assessment. If needed, the RN will facilitate a 4th generation rapid HIV test or draw HIV serology. A general review of systems, focused physical exam with emphasis on sexually transmitted infections and signs of seroconversion is provided, including identifying signs of genitourinary infection. The nurse will order labs per standing order and performs blood draw. Pre-test and Post-test counseling with HIV and STI testing is provided at this time. Upon receipt of a negative HIV rapid or serology test, PrEP-RN provides a 7-14 day supply of samples with a 30-day prescription of FTC/TDF (Truvada) or a 30-day prescription of FTC/TAF (Descovy) per standing order. At each follow-up visit, client's self-efficacy, attitudes/beliefs about PrEP, general health indicators, and social determinants of health, such as access to transportation and housing status, are recorded. Process evaluation will be performed to determine relationships of these variables and PrEP adherence, implementation (12 months), and continuation/dissemination (year 2) phases of the study.
Through the proposed Substance Checking Outreach and Pre-Exposure Prophylaxis (PrEP) Engagement (SCOPE) study, the investigators will design and evaluate an overdose prevention and HIV prevention study among people who use drugs (PWUD). Specifically, SCOPE will provide access to drug-checking services for PWUD to better understand the contents of the drug supply, in combination with PrEP for those who are HIV-, to both reduce overdose and HIV among PWUD in Baltimore City.
The goal of phase 1 is to determine the feasibility and acceptability of an intervention ('Rapid PrEP Access') providing people who use drugs (PWUD) one-time access to HIV self-testing at the Victory Program. Aim 1: To offer HIV self-testing to PWUD in the community through a study called 'Rapid PrEP Access'. The study will be carried out at the Victory Program. Aim 2: To determine the feasibility and acceptability of 'Rapid PrEP Access' at the Victory Program.
This is a research study to determine the best way to dose Truvada®, an oral medication licensed to be taken as Pre-Exposure Prophylaxis (PrEP) to prevent HIV infection, in transgender women who are also taking feminizing hormones. The duration of the study is about 4 months, and involves a screening visit, a baseline visit with colon biopsies and kidney function testing, and several outpatient visits, including 5 intensive sampling visits that last about 9 hours and involve colon biopsies, kidney function testing and other blood specimen collections. After the baseline visit, participants will start on PrEP, daily Truvada® pills, and will continue on the Truvada® for 5 weeks. Participants will then receive either an injection of Lupron, oral low-dose estradiol or oral high-dose estradiol, which will be taken along with the Truvada® PrEP for 1-2 weeks before returning for an intensive sampling visit.
This randomized controlled trial will test the efficacy of "PrEP for Health," a behavioral intervention to improve the use of antiretroviral pre-exposure prophylaxis (PrEP) among at-risk people who inject drugs (PWID) in two syringe service program (SSP) settings in Lawrence and Boston/Cambridge, Massachusetts. The investigators will equally randomize 200 PWID to receive either (a) the "PrEP for Health" intervention condition involving theory-informed HIV and PrEP education, motivational interviewing, problem-solving and planning, and ongoing patient navigation (n=100), or (b) the standard of care condition involving PrEP information and referrals (n=100). Successful PrEP uptake (via medical/pharmacy records), post-treatment PrEP adherence (assessed at 3 months via drug levels in hair), and longer-term PrEP adherence (assessed at 6 and 12 months via drug levels in hair) will be evaluated. The degree to which intervention efficacy occurs through specific conceptual mediators and differs according to hypothesized moderators will also be evaluated.
The objective of this application is to increase PrEP uptake among AA women vulnerable to HIV acquisition in the rural South, specifically those seeking care at Federally Qualified Healthcare Centers (FQHC) in rural Alabama. The investigators will use a mixed-methods approach to adapt and pilot test a patient-provider communication tool from the CDC PrEP toolkit that focuses on the first three steps of the PrEP cascade (e.g., recognizing HIV risk, identifying as a PrEP candidate, and interested in PrEP) to increase PrEP uptake via referrals to local PrEP clinics.
Our proposed study will: provide a novel exploration of facilitators and barriers to PrEP; allow us to target hard to reach populations, including men who have sex with men (MSM) and substance users (both of which are top funding priority groups for the National Institutes of Health) who experience intersecting markers of HIV risk; and inform regional, and possibly national, intervention approaches to combat the overlapping epidemic of HIV and incarceration.
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.
This study is a randomized controlled clinical trial of a theoretically based mobile app, HealthMindr, to increase pre-exposure prophylaxis (PrEP) uptake among men who have sex with men (MSM) to prevent human immunodeficiency virus (HIV). Participants in the intervention arm will receive access to the HealthMindr app, with information about PrEP and other HIV prevention methods in addition to provider locators. Participants randomized to the control arm will receive standard of care. The primary aim for this study is to assess PrEP uptake in the intervention arm compared to the control arm.
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.
This study uses an ingestion sensor and a wearable sensor (worn as a patch on the skin), which are new Proteus Digital Health (PDH) technologies approved by the FDA, to collect information about patients taking their Pre-Exposure Prophylaxis (PrEP) medication for HIV prevention. The wearable sensor records information, which is uploaded wirelessly to a mobile device and then to a secure computer. Together the sensors and the mobile device transmitting the information to the study computer are called a digital health feedback system (DHFS), which gives healthcare providers information about when patients have taken their PrEP medication. The purpose of the study is to demonstrate that the DHFS is easy to use and acceptable to people taking PrEP; that patients will persist with its use; and that the system provides valid, accurate measures of adherence.
This study is a randomized clinical trial of PrEP@Home, a home care system for Human Immunodeficiency Virus (HIV) Pre-Exposure Prophylaxis (PrEP). Individuals entering into PrEP care at an initial in-person study visit will be randomized to the PrEP@Home system for home-based PrEP care follow-up visits or to the control standard of care for clinic-based follow-up visits. The primary aim of this study is to assess protective levels of PrEP medication for the intervention arm compared to the control arm.
Pepped on PrEP is an innovative pilot RCT designed by an interdisciplinary team to develop a counseling and problem-solving PrEP adherence intervention with a Behavioral Activation (BA) approach that aims to re-engage participants in safe but pleasurable activities in life and addresses stimulant-abuse as well as associated factors including depression, as barriers to optimal PrEP adherence.
This is an open-label, steady-state study of Tenofovir (TFV) and Emtricitabine (FTC) pharmacokinetics (PK) in transgender women taking feminizing hormones. Half of the participants will be transgender women on feminizing hormones, the other half will be male volunteers not taking any hormone therapy.
Background: The Ebola virus causes a severe disease. It can be fatal. The usual incubation period after being exposed is 2 to 21 days. There is no approved treatment for Ebola infection. There is also no vaccine to prevent infection either before or after exposure. Researchers want to test an Ebola vaccine. They want to give it to people before they are exposed to the virus in order to prevent the disease. Objectives: To see how long-lasting and effective the vaccine rVSV\[delta\]G -ZEBOV-GP (V920) is at preventing Ebola. Eligibility: Healthy adults at risk of exposure to the Ebola virus at work through lab or clinical contact. Design: Participants will be screened with medical history, physical exam, and blood tests. Participants will get the study vaccine. It will be injected into their upper arm. Participants will be monitored closely for at least 30 minutes. They will get a diary card to record any symptoms they have from the vaccine for up to 14 days. Participants will have study visits at 1, 3, and 6 months after they get the vaccine, then every 6 months (that is, at months 12, 18, 19, 24, 30, and 36 of study) for a total of 36 months. Eighteen months after they join the study, participants will be randomly assigned to one of two groups. One group will get a second (or booster ) dose of the vaccine. The other group will not get a second dose. This study lasts 36 months. In December 2024, the study was approved to re-enroll up to 30 participants from the primary cohort to check longer-term immune response to the study vaccine beyond 36 months.
The purpose of this study is to test a program that uses drug level monitoring, text messaging ("iTAB") and personalized counseling with HIV prevention services, including PrEP (medicine that can help prevent HIV infection when taken daily).
The primary objective of this study is to define the mean, variance, and dose proportionality for tenofovir-diphosphate(TFV-DP) in dried blood spots resulting from 33%, 67%, and 100% of daily dosing with 200mg emtricitabine and 300mg of tenofovir disoproxil fumarate (as Truvada®). With this information, a model will be established to predict adherence rates to TFV-DP using DBS. Forty-eight healthy HIV-uninfected adult participants who are at low risk for HIV infection will be randomized to one of 6 sequences consisting of two directly observed dosing regimens, 33%/67%, 33%/100%, 67%/33%, 67%/100%, 100%/33%, and 100%/67% with each dose regimen lasting approximately 12 weeks, separated by an approximately 12 week washout period. DBS will be collected at regular intervals, including during the washout. The hypothesis of the study is that levels of TFV-DP in DBS will predict adherence rates in the preceding 1-3 months.
This is an observational study of HIV-1 negative individuals who participated in demonstration projects or clinical studies and took daily Emtricitabine/Tenofovir Disoproxil Fumarate (FTC/TDF, Truvada®) for pre-exposure prophylaxis (PrEP). All individuals were enrolled and followed as described in the parent PrEP demonstration project or clinical study protocol until study completion, HIV-1 infection, discontinuation due to an adverse event, lost to follow-up, or administrative censoring. In the protocols of the parent PrEP observational or clinical studies, participants had follow-up visits on average every 3 months for evaluation of adherence, renal and bone adverse events, and HIV-1 infection status. Adherence was determined by the specific FTC/TDF drug level measurement(s) outlined in the parent protocol. Gilead had collected data from 21 global PrEP demonstration projects and clinical studies for over 7,000 Truvada for PrEP users who had at least one measurement of adherence. Data from the different contributing studies were pooled for statistical analyses by Gilead.
This study will evaluate HIV-1 RNA and the presence or absence of resistance at baseline and following seroconversion, assess the frequency of HIV-1 screening and screening method(s) used for evaluation of seroconverters, and collect information regarding whether the seroconverter experienced signs and symptoms of acute HIV-1 infection prior to or at the time of seroconversion.
Black men who have sex with men (MSM) Pre-Exposure Prophylaxis (PrEP) Study with Client Centered Care Coordination (C4) Component.
This is a three phase study designed to examine clinician behaviors with regard to recommending and prescribing pre-exposure prophylaxis (PrEP) as a primary Human Immunodeficiency Virus (HIV) prevention strategy, and to identify knowledge-related and attitudinal factors associated with these behaviors. Each phase consists of the following: Phase 1: Semi-structured face-to-face or telephone interviews of ATN-affiliated clinicians. Approximately 10 clinicians will be interviewed. Phase 2: Development of a new theory-based survey instrument and cognitive interview testing of this survey. Approximately five clinicians (of those who participated in Phase 1) will be interviewed. Phase 3: Administration of the newly developed survey to ATN-affiliated clinicians. Approximately 60 clinicians will be interviewed.
This study will assess the uptake, acceptability, safety, and feasibility of HIV pre-exposure prophylaxis (PrEP), consisting of a once-daily fixed-dose combination tablet of emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF), administered at sexually transmitted disease (STD) clinics and a community health center in the United States.
Pre-exposure prophylaxis (PrEP) is a method of preventing HIV infection through the use of antiretroviral (ARV) medications before exposure to HIV. This study will examine the feasibility of different methods of dosing for a PrEP regimen. Three methods of delivery will be compared: daily, time-based, and event-based.
The main purpose of the study is to evaluate the safety and tolerability of oral Islatravir (ISL) once monthly (QM) as Preexposure Prophylaxis (PrEP) in cisgender men who have sex with men (MSM) and transgender women (TGW) who have sex with men and who are at high risk of HIV-1 infection with 48 or 96 weeks of treatment and a minimum follow-up of 42 days.
The long-term goal of this research is to develop a theoretically grounded, effective, accessible and sustainable mHealth PrEP care continuum intervention for racially/ethnically diverse transgender women (TW) and gay, bisexual, and other men who have sex with men (GBMSM) disproportionately impacted by the HIV epidemic. To reach this goal, the investigators will compare study outcomes among persons randomized to use a mobile app (eSTEP) intervention tailored to the unique needs of TW and GBMSM with interactive components delivered before in-person HIV testing and PrEP initiation visit and interactive components delivered after PrEP is initiated. The eSTEP group will be compared to usual HIV testing and PrEP care.
