Long-Acting HIV Pre-Exposure Prophylaxis Integrated With Sexual and Reproductive Health - cRCT

The goal of this hybrid (1a) Cluster Randomised Controlled Trial phase 3B trial is to evaluate the effectiveness and implementation of offering a choice of HIV Pre-Exposure Products (PrEP) through community-based sexual and reproductive health services, on PrEP uptake and retention, and population prevalence of sexually transmissible HIV amongst adolescents and young adults living in rural South Africa. Researchers will compare adding the choice of long-acting PrEP, i.e. two monthly injectable cabotegravir (CAB LA) or dapiravine vaginal ring and HIV post exposure prophylaxis packs to daily oral PrEP integrated with community-based SRH in the 20 intervention clusters with standard of care (SoC), daily oral PrEP integrated with community-based SRH in the 20 control clusters, on uptake and retention on PrEP. We hypothesise that offering a choice of long-acting or oral PrEP and PEP within the community-based delivery of SRH services will overcome the challenges and barriers to effective use of oral daily PrEP and lead to a population-level effect on uptake and retention on PrEP and thus the prevalence of sexually transmissible HIV amongst 15-30 year olds living in rural KwaZulu-Natal, South Africa.

A Study to Evaluate Efficacy, Safety and Tolerability in Antiretroviral Therapy (ART)-Experienced Participants of at Least 50 Years of Age Living With Human Immunodeficiency Virus (HIV) With Virologic Suppression Who Switch to DTG/3TC FDC From BIC/FTC/TAF

The study aims at evaluating the maintenance of virologic suppression of dolutegravir/lamivudine (DTG/3TC) fixed dose combination (FDC) at Week 48 post-switch from bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in participants living with Human Immunodeficiency Virus Type 1 (HIV-1) who are of at least 50 years of age and above.

Study Evaluating the Efficacy, Safety, and Tolerability of Switching to Long-acting Cabotegravir Plus Long-acting Rilpivirine From Current Antiretroviral Regimen in Virologically Suppressed HIV-1-infected Adults

The Antiretroviral Therapy as Long Acting Suppression (ATLAS) study is being conducted to establish if human immunodeficiency virus type-1 (HIV-1) infected adult subjects with current viral suppression on a regimen with 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus a third agent, remain suppressed upon switching to a two-drug intramuscular (IM) long-acting (LA) regimen of cabotegravir (CAB) and rilpivirine (RPV). This is a Phase 3, multi-phase, randomized, open label, active-controlled, multicenter, parallel-group, non-inferiority study in HIV-1, antiretroviral therapy (ART)-adult subjects who are stably suppressed on a current antiretroviral (ARV) regimen. This study is designed to demonstrate the non-inferior antiviral activity of switching to a two drug CAB LA 400 mg + RPV LA 600 mg regimen every 4 weeks (Q4W: monthly) compared with maintenance of current ARV regimen containing 2 NRTIs plus an INI, NNRTI, or a PI. Eligible subjects will be randomized (1:1) into the Maintenance Phase at Day 1 to either continue current ART or switch to initiate oral therapy with CAB 30 mg + RPV 25 mg once daily for 4 Weeks followed by Q4 weekly (monthly) CAB LA + RPV LA injections. Following the Maintenance phase at Week 52, subjects who were randomized to continue their current ART regimen will be given an option to switch to CAB LA + RPV LA injections. Those subjects would transition to LA dosing, beginning with 4 weeks oral CAB + RPV therapy at Week 52, and receive the first IM CAB LA + RPV LA injections at Week 56.

Risk of Morbidity, Mortality and Long-term Monitoring of Antiretroviral Treatment in People Living With HIV

HIV infection is now a chronic disease in countries where antiretroviral treatments (ART) are largely available. Long-term follow-up is required to describe and understand the evolution of morbidities and complications as well as new treatments side effects. The main objective of the cohort is to describe and study the evolution of HIV infection in ART-treated individuals.

Dasatinib for HIV-1 Reservoir Reduction

This study will test if the medicine dasatinib can lower the hidden amount of HIV in the body, called the HIV "reservoir." It will also check if dasatinib is safe and easy to take for people living with HIV who have a suppressed viral load while on antiretroviral therapy (ART). Adults 18 years or older who have been on ART for at least 48 months and have had a suppressed HIV-1 viral load for at least 36 months may be able to join. People will be randomly assigned to take dasatinib 100 mg by mouth once a day or a look-alike substance with no drug, called a placebo, for 12 weeks. Neither participants nor researchers will know who gets which (double-blind). The study team will do regular health checks and blood tests to track safety, tolerability, the HIV reservoir, and changes in immune cells. The study lasts 36 weeks total: 12 weeks of treatment and 24 weeks of follow-up, with clinic visits and possible phone calls. Fourteen people will take part; eight will get dasatinib and six will get placebo. Dasatinib may lower the HIV reservoir, but this is not guaranteed. All medicines can cause side effects, called adverse events (AE). The study team will watch closely and provide medical support. Joining is your choice, and you can leave at any time. If you leave, the team will talk with you about next steps for your care.

A Study to Investigate the Use of VH3810109 With or Without Fostemsavir (FTR) to Reduce the Size and Activity of the Viral Reservoir in People Living With HIV

This study investigates the use of VH3810109 with or without FTR to reduce the size and activity of the HIV viral reservoir in two sub-populations of people living with HIV: treatment-naïve adults (Population 1) and treatment-experienced adults currently taking a standard of care (SOC) integrase strand transfer inhibitor (INSTI)-based antiretroviral therapy (ART) regimen (Population 2). The study is designed to include the following phases: Randomized Intervention Phase (Step 1), Analytical Treatment Interruption (ATI) Phase (Step 2), and Follow-up Phase (Step 3).

Supporting Sustained HIV Treatment Adherence After Initiation

The investigators will implement a 24-month fractional factorial design study (Aim 1). The investigators will recruit 510 patients initiating antiretroviral therapy (ART) at three City of Cape Town ART clinics. Each patient will have adherence monitored using the Wisepill® electronic adherence monitoring device (EAM). After eligibility has been confirmed, each participant will be randomized to one of 16 experimental conditions. Each condition includes a unique combination of five adherence intervention components. Three of these components focus on identifying individuals with poor adherence, with increasing degrees of sophistication, with immediate linkage to adherence support. Two components focus on supporting good adherence. They both supplement the existing adherence support program delivered at the study clinics operated by City of Cape Town (standard of care component). Based on Self-Determination Theory, the investigators postulate these intervention components will: 1) enhance feelings of autonomy support, social support, and knowledge; 2) improve motivation and self-competence; and 3) increase ART retention, adherence, and viral suppression. A subset of the participants, as well as clinic staff, will be invited to in-depth interviews to explore mediating factors (Aim 1) and the implementation process (Aim 2); and the data collected in Aims 1 and 2 will be used to explore cost effectiveness (Aim 3).

A Study to Evaluate the Efficacy, Safety, and Tolerability of Using an Oral Once-daily 2 Drug Regimen Compared to an Oral Once-daily 3 Drug Regimen for the Treatment of Human Immunodeficiency Virus (HIV)-1 in Adults Who Have Not Previously Taken Antiretroviral Therapy

Infectious Disease (ID) Testing OUtreach in Carceral Hubs

This pilot feasibility study represents part 3 of a larger R61 study, where the investigators will follow a cohort about their experiences with human immunodeficiency virus (HIV) testing. This project aims to assess the effectiveness of an intervention at two jail sites in the Boston area: South Bay House of Corrections and Nashua Street Jail implemented in January of 2025 that is aimed at improving HIV testing practices and HIV treatment in those carceral facilities. This implementation was developed independently of the investigators' study activities. The jails worked to develop changes in their electronic health record to offer HIV testing at various points in their intake and physical exam process. HIV care was not well-integrated with the jails' existing intake and healthcare administration systems and medications for opioid use disorder (MOUD) program. The investigators will evaluate the intervention the jails developed to address these issues. The outcomes of interest are more implementation than effectiveness outcomes. The primary goal of this study is to identify existing barriers in the carceral healthcare setting that prevent the improvement of HIV testing and treatment.

The purpose of this study is to evaluate the safety and immunogenicity of mRNAs encoding HIV immunogens (eOD-GT8 60mer, core-g28v2 60mer, N332-GT5 gp151) in adult participants without HIV and in overall good health in South Africa.

Texting to Reduce Human Immunodeficiency Virus (HIV) Risk

This is a 3-year study to test the efficacy of a text message-based intervention program. Dental patients at 4 community health centers (n= 266) will be randomized to receive either text messages (TMs) regarding HIV prevention or TMs regarding overall wellness. Prior to enrolling the 266 participants, the investigators will conduct a feasibility pilot (n=20) to test the TM delivery as well as all study procedures. For both the pilot and the randomized clinical trial (RCT), recruitment will be conducted at 4 Community Health Center dental clinics (Codman Square, East Boston (both East Boston and South End locations), Geiger Gibson, and Upham's Community Health Centers). Recruitment materials (flyers and permission to contact forms) may also be made available at other clinics within the health centers. The study will enroll English and Spanish-speaking patients who have at least one risk factor for HIV but are HIV-negative. Patients enrolled in the pilot will complete self-report surveys at baseline, 1 and 2 months. Participants enrolled in the RCT will complete self-report surveys baseline, 3, 6, and 12 months after baseline; receive and respond to TM assessments during the 6-month intervention.

Impact of a Telenovela/Soap Opera for HIV Prevention in Latinas

Latinas continue to be affected disproportionally by HIV in the United States (US). Often, Latinas are not aware of their HIV status. Also, their perception of low risk for HIV interferes with condom use, HIV testing and lack of awareness, access, and use of Pre-exposure Prophylaxis (PrEP). About 60% of total HIV cases in NC occur among women of childbearing age, thus vulnerability to HIV is particularly acute among Latinas between ages 18 and 44 years old, an age group with the highest rate of new HIV infections in NC. These disparities indicate that HIV prevention among Latinas is urgent; therefore, the investigators propose an innovative intervention - a filmed dramatized story (telenovela/soap opera) Infección de Amor (IA) (Love Infection) - culturally tailored for Latinas in the US and delivered online. Infección de Amor was filmed and developed but has not been tested with the target audience. The proposed study will pilot test IA and move the intervention to online using a website that will allow individual access around the clock from any location and device, such as a smartphone, ensuring wide dissemination of the intervention in the future. This is a a two-year planning grant (R34) to prepare for an R01 efficacy trial. The aims are to: 1) Develop the intervention delivery website, conduct a website usability test, and test the feasibility and acceptability of the IA intervention (four telenovela episodes) with 10 Latinas, 2) Conduct a randomized controlled pilot study to examine change in HIV prevention behaviors (condom use; HIV testing; and PrEP awareness, access, and use) comparing intervention and control Latinas from baseline (Time 1 \[T1\], 0 months) to post-active intervention (Time 2 \[T2\], 1 month), and to six months follow-up, a period with no contact from the study staff (Time 3 \[T3, 7 months\]), and 3) Complete establishing the study infrastructure, expanding the multidisciplinary team, building the research partnerships with the community, finalize the protocol and training materials, refine recruitment and retention strategies, data collection and data management procedures, and obtain institutional review board approval in preparation for an R01 efficacy study. This study address the National Institute on Drug Abuse (NIDA) goal #4: increase NIDA research and programs' public impact. This is a novel intervention to advance HIV prevention for Latinas. This study implement a culturally durable and feasible intervention for Latinas.

An mHealth Intervention to Improve HIV Prevention Service Engagement Among People Who Use Drugs

The goal of this single arm pre-post study is to assess the feasibility, acceptability, and preliminary impact of the LOTUS intervention to improve HIV prevention service engagement among people who use drugs. LOTUS is a technology-delivered intervention that provides HIV prevention informational content and tips, peer social support and social networking features, a resource locator, HIV prevention monitoring and reminders (e.g., reminders for HIV/STI testing and PrEP doses), and a virtual space to have questions answered by health care professionals.
