Hiv Infections

VH4770359 (also known as GSK4770359) is an antiretroviral compound. This first-in-human study aims to evaluate the safety, tolerability, and pharmacokinetics (PK) of orally administered VH4770359 in healthy participants. The findings from this study will support the design of future clinical studies of VH4770359 in people living with HIV.

The purpose of the study is to assess the bioavailability, mass balance, pharmacokinetics, metabolism and excretion of radiolabeled (14C) VH4524184.

The purpose of this study is to identify 1 or more doses of parenterally administered VH4524184 that are safe, well tolerated and yield a PK drug exposure profile necessary to deliver a long-acting antiretroviral therapy for the treatment of HIV-1 infection.

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.

The goal of this observational study is to generate real-life information on the use of lenacapavir (LEN, YEZTUGO®, (YTG)) for pre-exposure prophylaxis (PrEP) across diverse clinical settings in the United States. The study will characterize how PrEP is initiated, used, and discontinued in routine clinical practice when LEN is added as PrEP option and will evaluate persistence on LEN PrEP. The primary objective of this study is to evaluate real-life persistence on LEN PrEP at Week 52 in diverse clinical settings in the United States.

This study evaluates strategies to improve access to HIV prevention through the integration of pre-exposure prophylaxis (PrEP) into existing healthcare settings, rather than limiting delivery to specialty clinics. The study addresses barriers to PrEP uptake, including limited awareness, stigma, and restricted access, and recognizes that availability alone may not ensure initiation or sustained use. The study includes two components. First, a longitudinal cohort of current PrEP users will be followed to assess changes in access, preferences, and PrEP use over time in real-world settings. Second, a dynamic decision-support toolkit will be developed and evaluated to support patients and providers in PrEP-related decision-making. The toolkit will include patient- and provider-facing components to support clinical decision-making, improve risk understanding, and facilitate integration of PrEP into routine healthcare. The toolkit will be refined and beta-tested in selected healthcare facilities in Botswana and Alabama.

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.

This study compares the efficacy, safety and tolerability of CAB ULA and RPV ULA administered with CAB long acting (LA) and RPV LA administered in adults and adolescents with HIV who are virologically suppressed on anti-retroviral therapy (ART).

This multicenter study evaluates a full-situational awareness robotic bronchoscopy system combined with CBCT-based multimodal image fusion for diagnosing lung nodules in people living with HIV (PLWH). Lung nodules are small lesions that may be benign or cancerous. In PLWH, accurate diagnosis is especially important but challenging. In this study, participants will be assigned to one of two groups: * Experimental group: Robotic bronchoscopy with real-time full-situational awareness and CBCT image fusion; * Control group: Electromagnetic navigation-guided bronchoscopy combined with radial endobronchial ultrasound (EBUS). In both groups, rapid on-site cytologic evaluation (ROSE) will be performed to confirm tissue adequacy. For participants confirmed to have lung cancer and meeting safety criteria, an exploratory transbronchial cryoablation will be performed during the same procedure. The study aims to compare diagnostic accuracy and safety between the two approaches and to explore the feasibility of immediate cryoablation for early-stage lung cancer in PLWH.

(Effectiveness Aim 1) To test the comparative effectiveness of PreP for WINGS versus PrEP alone on primary outcomes of increasing PrEP initiation measured by self-report/medical records, recent adherence and longer-term adherence by self-report/medical records over the 6-month follow-up; and secondary outcomes of decreasing IPV, hazardous drinking, recidivism, and HIV risks. (Moderation Aim 2) To test if the effectiveness of WINGS+PrEP on study outcomes is moderated by key participant subgroups based on race/ethnicity, sexual orientation, age, education, incarceration history, IPV severity, substance use disorders (SUDs), digital access and literacy, housing stability, and medical mistrust.

This is an exploratory qualitative study among People Living With HIV (PLWH) of diverse racial/ethnic and sexual and gender minority (SGM) identities to explore individual, interpersonal, and structural oral health equity factors that serve as barriers or facilitators of accessing oral health care, knowledge and perceptions of human papillomavirus (HPV) vaccination and Oral squamous cell carcinoma (OSCC) /Oropharyngeal squamous cell carcinoma (OPSCC), and to collect recommendations on how to increase access to oral health care and engage PLWH in OSCC/OPSCC prevention.

Our goal is to optimize LAI-PrEP implementation within the context of other PrEP methods. Our strategy is flexible to allow pivot to include forthcoming PrEP dosing options should they become available

This is a multi-phased study, funded through a National Institute on Drug Abuse (NIDA) K24 grant that aims to ultimately refine a virtual reality tool through qualitative and quantitative research targeting HIV and substance abuse risk behavior among at-risk young people who have experienced psychosocial trauma. Participants eligible for this study include young men who have sex with men (YMSM)/individuals who are romantically/physically attracted to men and adolescents with substance use disorder (SUD) between the ages of 15 - 30 and have experienced at least one traumatic event in their lifetime. Frontline healthcare workers who work within these populations are eligible for the study as well.

The clinical schedule will consist of 3 injections of CD40.HIVRI.Env (VRIPRO) at weeks 0, 4, and 24.40 volunteers without HIV and in overall good health, aged 18 to 60 years, who previously participated in the HVTN 706 trial.

The investigators are studying whether metabolic abnormalities in calf (leg) muscle in older people with and others without HIV are associated with decreased abilities to exercise.

The investigators plan to conduct an R61/33 hybrid type 2 implementation-effectiveness trial that includes 1) a one-year exploratory R61 phase that will enable the development of the intervention protocol needed for the R33 trial phase including concrete R61 phase milestones; 2) a four-year R33 phase that will include a concurrent implementation evaluation and a randomized control trial.

This randomized, placebo-controlled trial will evaluate self-administered 5-fluorouracil (5FU) to improve human papillomavirus (HPV) clearance after thermal ablation (TA) in Women With Human Immunodeficiency Virus (HIV) (WWH) in Kenya. The trial will also assess the safety, adherence, and acceptability of 5FU. Starting four weeks after TA, participants will self-administer 5FU cream or matched placebo intravaginally once every other week for 12 applications, with clinic visits at weeks 2, 8, 16, 24, and 48 for evaluation. All participants will be followed up to 48 weeks. It is hypothesized that, compared to placebo, 5FU will increase HPV clearance at 24 weeks and that the proposed dosing schedule will be safe, well-tolerated, and acceptable in this population. Together with data from other studies, this trial will provide evidence on the use of self-administered intravaginal 5FU to improve HPV treatment outcomes in WWH in low- and middle-income countries, where the burden of cervical cancer is highest.

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.

This Clinical Trials Network for Human Immunodeficiency Virus (HIV)-Associated Cervical Cancer Screening and Treatment Optimization (CASCADE)-3001-B trial aims to assess how the introduction of a community-health-worker-facilitated model, in addition to the existing static clinic-only model, influences the rates of cervical cancer screening uptake among women living with HIV (WLWH). This study involves offering human papillomavirus (HPV) self-collection for cervical cancer screening to eligible WLWH. The 'CASCADE' Network is a clinical trials network aimed at improving cervical cancer screening, management, and pre-cancer treatment for WLWH, in various healthcare settings. The network will conduct implementation trials to improve the triage of HPV-positive WLWH, as well as algorithms to optimize access to and options for effective treatment. Trials will be conducted using a mixed-methods approach aimed at assessing implementation strategies and outcomes and their potential to integrate into existing health systems. Further understanding of HPV-based community-based strategies to reach WLWH, and the acceptability, feasibility, appropriateness, and cost of these strategies will be valuable for cervical cancer screening programs serving WLWH. Inputs from various 'CASCADE' Clinical Sites (CS) regarding feasible screening outreach options available in their settings for WLWH have guided this study that focuses on evaluating a pragmatic HPV self-collection implementation model to improve access to screening. While it is clear that HPV self-collection is a highly acceptable and feasible screening option, creating opportunities to conduct self-collection in alternative venues outside the clinic premises, and with the guidance of and facilitation by trusted community healthcare workers (CHWs) is an important implementation strategy that needs to be evaluated and considered for its potential benefit. Studies have not yet evaluated a community-based approach for HPV self-collection kit distribution among WLWH - who may have different characteristics, preferences, and access to screening services than women not living with HIV. Providing WLWH with the option of receiving HPV self-collection kits in their own homes or other community-based settings ('community-based HPV self-collection') is a novel implementation strategy that could improve cervical cancer screening rates among eligible women. Therefore, this novel trial aims to evaluate the feasibility and effectiveness of implementing community-based HPV self-collection among WLWH.

The goal of this clinical trial is to learn if the WeCare intervention-an adapted Friendship Bench program that integrates problem-solving therapy, minority-stress-informed content, and explicit PrEP/ART adherence skills-improves mental health and HIV medication adherence among men who have sex with men (MSM). It will also assess the safety, acceptability, and feasibility of delivering WeCare through trained lay coaches in community clinics. Main questions the trial aims to answer: * Does WeCare reduce symptoms of depression and anxiety among MSM? * Does WeCare improve PrEP and ART adherence and increase rates of viral suppression among participants on ART? * Is WeCare acceptable, feasible, and safe when delivered by lay coaches in POP INN clinics compared with usual care?

The purpose of this study is to advance pediatric HIV treatment and cure research by evaluating the impact of a combination of three anti-HIV-1 broadly neutralizing antibodies (bNAbs) or analytic treatment interruption (ATI) on viral reservoir, immune function, and maintenance of HIV suppression in early-treated children.

The goal of the TAIL-PrEP study is to understand how to support the safe discontinuation of injectable long-acting cabotegravir (cab-LA) and lenacapavir (LEN) while maximizing the public health impact of biomedical HIV prevention interventions. In Aim 1, the study will pilot test and assess the acceptability and feasibility of the TAIL-PrEP intervention: for participants discontinuing cab-LA, this will consist of monthly cabotegravir drug level monitoring to provide personalized HIV prevention coaching, for participants considering discontinuing cab-LA or LEN, this will consist of a one-time personalized HIV prevention coaching session. In Aim 2, the study will refine the TAIL-PrEP intervention and implementation strategy based on findings from the pilot study.

This is a prospective, adaptive, randomized controlled trial comparing the effectiveness of 4 intervention arms on a combined endpoint in adults with confirmed MDR-TB HIV initiating Bedaquiline-containing MDR-TB treatment regimens and on ART (integrase strand transfer inhibitor (INSTI)-based fixed dose combination therapy) in KwaZulu-Natal, South Africa. Interventions arms include: enhanced standard of care; psychosocial support; mHealth using cellular-enabled electronic dose monitoring; combined mHealth psychosocial support. Level of support will be adjusted using a differentiated service delivery (DSD)- informed assessment of treatment support needs.

Multinational Observational Cohort of HIV and other Infections (MOCHI). This observational study is to gain information regarding the number of new HIV infections among people who engage in behaviors that make them vulnerable to acquiring HIV across multiple international sites.
