Pharmacokinetic Study of Long-acting Antiretrovirals and Contraceptives in HIV

This study is being done to understand how long-acting injectable cabotegravir (CAB-LA) used for HIV pre-exposure prophylaxis (PrEP) and hormonal contraceptive methods affect each other when used at the same time. Women who are already using CAB-LA or not using PrEP will choose to join one of several groups based on whether they use injectable contraceptive (IM DMPA), an etonogestrel implant, or no hormonal contraceptive. Participants will have study visits every 4 to 12 weeks for up to 12 or 24 weeks after starting a contraceptive method to collect blood samples and measure levels of CAB-LA and hormone concentrations. The study will compare these levels to see if taking CAB-LA changes hormone concentrations or if using hormonal contraception changes CAB-LA drug levels. Safety, side effects, satisfaction, and continuation of CAB-LA PrEP and contraceptive methods will also be evaluated.

Tu'Washindi RCT: Adolescent Girls in Kenya Taking Control of Their Health

This study will test the effectiveness of a youth-designed multilevel intervention, Tu'Washindi, to increase PrEP use and reduce intimate partner violence (IPV) among Kenyan AGYW and to identify implementation challenges and strategies to facilitate future scale-up in programmatic settings to maximize public health impact. Through a cluster randomized controlled trial (cRCT) design, twenty-two administrative wards in Siaya County, western Kenya will be randomized in a 1:1 ratio to receive either the 6-month Tu'Washindi intervention plus usual HIV prevention services or usual HIV prevention services alone. Approximately 72 AGYW will be enrolled from each ward (N= 1,584), with follow-up visits at months 3, 6, and 12 post-enrollment. A mixed methods process evaluation (not part of the clinical trial) will also be conducted using programmatic data, follow-up questionnaires from trial participants, approximately 500-1000 exit surveys with men, and approximately 100 qualitative interviews with AGYW participants, male partners, and intervention providers. These data will characterize fidelity and quality of intervention implementation, explore and test mechanisms of change, and capture contextual factors influencing intervention outcomes, with the goal of informing future refinement and implementation. The population for this clinical trial study is AGYW ages 15-24 in Siaya County, Kenya.

Bringing Medicines for HIV Prevention to a Family Planning Clinic

The goal of this clinical trial is to understand what patients and physicians think about providing medications to prevent HIV transmission to patients in a family planning clinic. These medications are known as pre-exposure prophylaxis, or PrEP. The main questions to answer are: 1. Do patients find it acceptable to be asked about, and offered, PrEP during their visit to a family planning clinic? 2. What things make it easier or harder to ask about PrEP in a family planning clinic setting? 3. What things make it easier or harder to begin PrEP in a family planning clinic setting? Patient participants: 1. Will receive standardized counseling about PrEP. 2. Will have the opportunity to begin PrEP as part of their routine, ongoing care. 3. Will be asked to complete a survey about their experiences. Physician participants: 1. Will receive standardized education about PrEP. 2. Will talk to patient participants about PrEP, and support patient participants who want to begin PrEP. 3. Will be asked to complete pre-and post-study surveys about their experiences. 4. May be asked to complete a post-study in-depth interview about their experiences.

A Multi-Level Trauma-Informed Approach to Increase HIV Pre-exposure Prophylaxis Initiation Among Black Women

U.S. epidemiological data indicates that Black women are a high-risk HIV disparity group, yet initiation of novel prevention strategies like pre-exposure prophylaxis (PrEP) among this group is stagnant. Socio-structural challenges like intimate partner violence and gendered racism can constrain PrEP access among Black women, but few implementation studies have mitigated these challenges to improve PrEP initiation. The proposed research aims to implement and assess the effectiveness, implementation, and sustainability of a multilevel intervention to increase PrEP initiation among Black women with and without intimate partner violence in Baltimore.

HIV Pre-Exposure Prophylaxis (PrEP) Linkage With Immediate Medications in the Emergency Department Study

Our primary objective is to increase HIV pre-exposure prophylaxis (PrEP) awareness and uptake among people who want, need, or would benefit from PrEP in Dallas, TX through a pilot program of immediate PrEP prescribing in the Parkland Memorial Hospital Emergency Department (ED) with linkage to PrEP clinic. Leveraging the previous work of the Parkland Center for Clinical Innovation (PCCI) which created an automated electronic health record (EHR) based HIV prediction tool and prior success with a robust ED HIV navigation program, a PrEP navigator would approach patients in the Parkland ED for PrEP initiation. Through standard care prescribing by their ED clinician, subjects would leave the ED with a prescription for rapid-start oral PrEP and a clinic appointment to persist on the PrEP modality of their choice which will include long-acting injectable options.

Using PrEP, Doing It for Ourselves

The goal of this clinical trial is to test a new online program called UPDOs Protective Styles to help people in the southeastern United States learn about and start using PrEP (pre-exposure prophylaxis), a medicine that helps prevent HIV. The study focuses on people who may be at higher risk for HIV and have not had equal access to PrEP. The main questions it aims to answer are: Does UPDOs help more people trust and understand PrEP? Does UPDOs increase the number of people who start and continue using PrEP? Researchers will compare two groups: One group will use UPDOs, which includes six weekly videos, blog discussions, and access to telehealth services through Q Care Plus. The other group will receive standard HIV prevention materials from the CDC. Participants will: Be recruited from 32 beauty salons in areas with high HIV rates. Complete surveys at the start of the study and again at 6, 12, 24, 32, and 52 weeks. Have access to HIV testing and PrEP prescriptions through Q Care Plus. This study will also look at how well the program works in different communities and how easy it is to use and share.

Prevention ICONA Dedicated Ensemble

Despite significant advances in HIV treatment, transmission remains a public health concern. In 2022, there were 1.3 million new HIV infections worldwide and 1,888 new diagnoses in Italy, with sexual transmission being the predominant route. Many individuals are still diagnosed late, and a portion of people living with HIV are unaware of their status. Pre-Exposure Prophylaxis (PrEP) has emerged as an effective biomedical strategy to prevent new infections, especially when integrated into comprehensive prevention efforts. Study Objectives The primary objective of this observational study is to establish a large prospective cohort of individuals using PrEP in Italy. The study aims to assess PrEP's effectiveness, tolerability, adherence, and barriers to long-term use in a real-world setting. These data will be instrumental in guiding future strategic interventions to optimize PrEP management and move toward the goal of zero new HIV infections in Italy. Primary Objective * To assess the incidence of new HIV infections among PrEP users in Italy. Secondary Objectives * Incidence of other sexually transmitted infections (STIs); * Tolerability of PrEP; * Psychological and behavioral aspects related to PrEP use; * Adherence and persistence in care; * Use of therapies and prophylaxis for STIs during PrEP use. Study Design and Coordination This is a prospective observational study, promoted by Fondazione ICONA in collaboration with clinical centers and community-based organizations. The coordinating enrolling center is INMI "L. Spallanzani" IRCCS in Rome. Participating Centers: * 49 university and hospital-based centers across Italy; * 4 non-clinical checkpoints offering PrEP screening, prescription, and follow-up. Study Population Adults (≥18 years) who are HIV-negative, sexually active, and considered eligible for PrEP per national or international guidelines, including both new and current PrEP users. Inclusion Criteria * Age ≥18 years; * Negative HIV test at enrollment; * Willingness to initiate or continue PrEP; * Informed consent provided. Exclusion Criteria * HIV infection or strong suspicion of infection; * Contraindications to PrEP medications; Known allergy to PrEP components; Refusal to comply with study procedures.

Behavioral Intervention for PrEP Service Utilization Among Chinese MSM: A HAPA and CEI Integrated Model

The goal of this clinical trial is to evaluate the effectiveness of a novel, intelligent intervention platform in bridging the "intention-behavior gap" for pre-exposure prophylaxis (PrEP) uptake among men who have sex with men (MSM) in China, a population at high risk for HIV infection. The study aims to address the following main questions: * Can the intervention platform, guided by the Health Action Process Approach (HAPA) and Conditional Economic Incentive (CEI) dual-track theoretical framework, significantly increase PrEP initiation rates among MSM? * What are the key mechanisms and pathways underlying the transition from PrEP intention to actual usage behavior? Researchers will compare participants receiving the intelligent intervention platform (intervention group) with those receiving basic PrEP information (control group) to determine the platform's impact on PrEP initiation rates. Participants will: * Use a mobile health platform equipped with personalized HIV risk assessments, PrEP knowledge resources, action planning tools, peer support features, and economic incentives. * Complete baseline and follow-up surveys at 3 months and 6 months to assess PrEP initiation, adherence, and related behaviors. * Engage in peer group activities and receive tailored feedback based on their progress. This study seeks to provide evidence for scalable and sustainable strategies to improve PrEP uptake and contribute to HIV prevention efforts in high-risk populations.

Development of a Predictive Model for Sexually Transmitted Infections in Individuals Using Pre-Exposure Prophylaxis for HIV in Spain

Objective: To develop and validate a predictive model for acquiring sexually transmitted infections (STIs) in individuals using HIV pre-exposure prophylaxis (PrEP) within the national program providing this strategy. Methods: Ambispective cohort study, multicentric (23 Spanish hospitals). All PrEP users, with follow-up within the program, will be included. Entry into the program will be considered as the baseline visit. From there, patients are followed quarterly, following the national protocols for monitoring PrEP users in Spain. At each visit, diagnosis of different STIs (serum, pharyngeal swab, urethral or urine sample, rectal swab, endocervical/vaginal swab, ulcer) is performed. Primary outcome variable: development of an STI (Yes/No). The following STIs will be considered: syphilis, Neisseria gonorrhoeae (NG) infection, Chlamydia trachomatis (CT) infection, lymphogranuloma venereum (LGV), Mycoplasma genitalium (MG) infection, genital herpes, hepatitis A, hepatitis B, hepatitis C, HIV infection, and MPOX. Secondary outcome variable: number of diagnosed STIs. In order to determine factors associated with acquiring an STI, multivariate analyses will be conducted using logistic regression. The best models will be analyzed in the validation population. To compare the models, we will follow the Bayesian approach suggested by Benavoli et al.
