This study is testing a lab-made antibody called ePGT121v1-LS that targets a specific part of HIV. Researchers will give it by vein (IV) and under the skin (SC), both on its own and together with two other antibodies, VRC07-523LS and PGDM1400LS, which target different parts of the virus. They will assess safety and side effects, determine the right dose, study how the body processes the drug (pharmacokinetics or PK), and measure how well it neutralizes HIV in the blood (serum neutralizing activity). The expectation is that ePGT121v1-LS, whether given alone or with PGDM1400LS and VRC07-523LS, by IV or SC, will be safe in generally healthy adults and that the antibodies will not interfere with each other when used together. Approximately 83 volunteers in overall good health and without HIV-1 will be enrolled into two parts (A and B). Part A has six groups. In Groups 1-3, participants will get ePGT121v1-LS given by IV at one of three dose levels: 5 mg/kg, 20 mg/kg, or 40 mg/kg. In Groups 4-6, participants will receive three antibodies-first ePGT121v1-LS, then PGDM1400LS and VRC07-523LS-given by IV at two separate visits that are 24 weeks apart. The total study duration for participants in Part A is 48 weeks of scheduled clinic visits. Part B has two groups. In Group 7, people will get ePGT121v1-LS as SC shots at two visits 12 weeks apart. Each visit will give a total of 375 mg, split into three injections of 125 mg each. In Group 8, people will also have two visits 12 weeks apart and will receive three antibodies as SC shots in this order: first ePGT121v1-LS (125 mg), then PGDM1400LS (100 mg), and then VRC07-523LS (100 mg). The total study duration for participants in Part B is 24 weeks of scheduled clinic visits.

This is a phase 1, multicenter, open-label, dose escalation, first-in-human (FIH) trial to evaluate the safety and immunogenicity of DV201P-RNA and DV202B1-RNA, immunogens designed to induce HIV-1 envelope (Env) V2 apex-specific broadly neutralizing antibodies (V2 apex bnAbs). Both vaccines consist of a modified mRNA encapsulated in lipid nanoparticles (LNP) that when translated in cells produces HIV-1 Env gp150 transmembrane trimers. The trial will enroll adult volunteers without HIV and in overall good health.

One in four older persons living with HIV/AIDS (PLWHA) report at least one suicide attempt in their lifetime, and the risk for death by suicide is 100 times higher in PLWHA than in the general population. Currently, there are no behavioral interventions that specifically address suicide prevention for older PLWHA, despite their unique biopsychosocial and structural risk factors. Through this work, investigators will adapt Dialectical Behavior Therapy, an evidence-based intervention for suicide prevention, for patients with PLWHA to be delivered by an AI-powered conversational Agent developed by our industry partner, Empower Health. Investigators will then pilot test the feasibility, usability, acceptability and preliminary efficacy to improve self-efficacy to manage negative emotions in n=50 older adults living with HIV/AIDS.

This project will explore the development of a personalized decision support tool to assist with pre-exposure prophylaxis (PrEP) initiation and persistence among patients identified in the emergency department (ED) and urgent care settings as PrEP eligible. First, the investigators will use a sequence of validated implementation science methodologies to develop and validate a decision support tool designed to optimize PrEP persistence by strengthening self-efficacy by addressing the multifaceted medical and social needs of the individual patient. The investigators will then test the preliminary effectiveness of this tool through a pilot stepped wedge implementation trial in two EDs and an urgent care in Baltimore, MD and Washington, DC among 120 PrEP eligible patients to determine PrEP initiation, linkage to care, persistence, and adherence rates.

H. pylori is an infection of the stomach that can cause chronic gastritis, gastric cancer and peptic ulcer disease. The goal of this study is to screen people for this infection and offer treatment for those who test positive for the infection. By treating those who are positive for H. pylori, there is an opportunity to prevent gastritis, peptic ulcer disease, and even gastric cancer.

The goal of this study is to examine two types of olfactory interventions (olfactory training vs overnight odor diffuser) in adults with HIV. The two research questions are: 1. Determine if participants find the intervention acceptable and assess feasibility of the study. 2. Determine if the intervention improves olfactory function and cognitive function. Participants will come to our office and be administered the baseline battery of questions including olfactory and cognitive performance tests. Then they will be randomized and sent home with one of the two interventions (below) in which they will engage in it for 8 weeks, after which they come back to our office for the posttest battery of questions including olfactory and cognitive performance test. 1. Olfactory Training at Home -- 4 scents in which they will smell twice a day for 8 weeks. 2. Overnight Diffuser Group -- a single scent diffuser that participants will turn on while they sleep and use for 8 weeks.

This study is testing software designed to help healthcare providers choose the best HIV treatment combinations for their patients. HIV medicines, known as antiretroviral therapy (ART), can be complex to manage because the right regimen depends on many factors-such as drug resistance, other health conditions, and medication schedules. Many people with HIV are cared for by general clinicians who may not have access to HIV specialists, which can make treatment decisions more challenging. In this study, healthcare providers will use patient cases to compare standard HIV treatment resources with a new clinical decision support tool that gives evidence-based ART recommendations at the point of care. The investigators hypothesize that using the tool will help providers select treatment plans that better match clinical guidelines, make decisions faster, reduce mental effort, and increase overall satisfaction with the prescribing process.

This research study aims to find out how safe and well tolerated the experimental study drugs are when given to persons with HIV (PWH) taking antiretroviral therapy (ART). The study treatments are MGD014 and MGD020, which are two antibodies developed specifically for HIV, and Vorinostat, an oral medication to help expose HIV in cells to the antibodies. The study will measure the impact of study treatment on non-active HIV in cells, and how long MGD014 and MGD020 stay in the body after they are given. In this study, participants will be randomly assigned to one of three groups. All participants receive MGD014 and MGD020, given sequentially as infusions through an IV for 4 doses. Participants in one group (group A) receive only MGD014 and MGD020. Participants in another group (group B) will stop taking their ART therapy for up to 8 weeks (a temporary treatment interruption (TTI)) while receiving MGD014 and MGD020. Participants in the third group (group C) receive Vorinostat in addition to MGD014 and MGD020. Total time of participation is about 8 months and involves 13 or 18 visits, depending on group assignment.

The goal of this randomized controlled trial is to pilot test new mobile health (mHealth) interventions to improve PrEP adherence among HIV-negative men who have sex with men (MSM) with mild to moderate methamphetamine use disorder (MUD). The CHAMPION intervention combines two mHealth tools-PrEPAPP and CBT4CBT-to address both HIV prevention and MUD treatment needs in this population. The study's specific aims are: * To evaluate the feasibility and acceptability of the CHAMPION intervention based on treatment retention and engagement rates. * To examine the preliminary efficacy the CHAMPION intervention to improve PrEP adherence, as measured by dried blood spot (DBS) tests compared to the waitlist control group.

This is an open-label, single center study to evaluate implementation of a pharmacist-managed delivery of L4P in a community pharmacy setting and the impact of twice-yearly vs. quarterly PrEP visits on STI rates.

This study is being done to test whether a drug called baricitinib, which blocks specific causes of inflammation, affects HIV-1 viral rebound and viral load levels after HIV treatment is discontinued. Researchers will test the effects of continuing baricitinib in people with HIV before and after discontinuing their antiretroviral therapy. This drug is approved by the Food and Drug Administration (FDA) for other diseases; it is not approved for the treatment of HIV-1. The study team will also investigate any side effects associated with the drug.

The goal of this study is to determine the feasibility and impact of delivering long-acting injectable cabotegravir HIV pre-exposure prophylaxis and suite of support services to adults who inject non-prescription drugs who are risk for HIV through known sexual risk.
