The purpose of this study is to learn the best approach to treating patients with known or suspected Barrett's esophagus by comparing endoscopic surveillance to endoscopic eradication therapy. To diagnose and manage Barrett's esophagus and low-grade dysplasia, doctors commonly use procedures called endoscopic surveillance and endoscopic eradication therapy. Endoscopic surveillance is a type of procedure where a physician will run a tube with a light and a camera on the end of it down the patients throat and remove a small piece of tissue. The piece of tissue, called a biopsy, is about the size of the tip of a ball-point pen and is checked for abnormal cells and cancer cells. Endoscopic eradication therapy is a kind of surgery which is performed to destroy the precancerous cells at the bottom of the esophagus, so that healthy cells can grow in their place. It involves procedures to either remove precancerous tissue or burn it. These procedures can have side effects, so it is not certain whether risking those side effects is worth the benefit people get from the treatments. While both of these procedures are widely accepted approaches to managing the condition, there is not enough research to show if one is better than the other. Barrett's esophagus and low-grade dysplasia does not always worsen to high-grade dysplasia and/or cancer. In fact, it usually does not. So, if a patient's dysplasia is not worsening, doctors would rather not put patients at risk unnecessarily. On the other hand, endoscopic eradication therapy could possibly prevent the worsening of low-grade dysplasia into high-grade dysplasia or cancer (esophageal adenocarcinoma) in some patients. Researchers believe that the results of this study will help doctors choose the safest and most effective procedure for their patients with Barrett's esophagus and low-grade dysplasia. This is a multicenter study involving several academic, community and private hospitals around the United States. Up to 530 participants will be randomized. This study will also include a prospective observational cohort study of up to 150 Barrett's esophagus and low grade dysplasia patients who decline randomization in the randomized control trial but undergo endoscopic surveillance (Cohort 1) or endoscopic eradication therapy (Cohort 2), and are willing to provide longitudinal observational data.

The goal of this Nutrition for Precision Health (NPH) powered by All of Us research study is to develop Artificial Intelligence/Machine Learning (AI/ML) algorithms that predict individual responses to diet patterns using rich multimodal data streams collected across multiple domains (e.g., behavior, social, environmental, clinical and molecular biomarkers). NPH includes a large phenotyping cohort (Module 1, N=8000) and two separate follow-up groups drawn from a subset of Module 1participants. One group (Module 2, N=1200) receives three distinct diets in a 14-day crossover sequence, with at least a 14-day washout period between diets, while living in their own homes. A second group (Module 3, N=150) receives the same three diets under full-time supervision in a residential research setting. We will train and test AI/ML models to predict 0-4 hour postprandial response curves for glucose, insulin, triglycerides, and GLP-1, to the standardized diet-specific meal test (DSMT) collected after each of the three different diets delivered in Module 2. Each diet functions as a controlled stimulus to reveal biological features (such as individual variables, patterns, or clusters of measurements) that best predict a person's response. The Module 2 DSMT response curves are the primary outcomes (dependent variables) for AI/ML algorithms that predict individual responses to diet patterns. As a secondary objective, NPH will evaluate the validity and acceptability of technology-based dietary assessment tools. The Automated Self-Administered 24-hour recall (ASA24), Automatic Ingestion Monitor-2 (AIM-2), and the mobile food record (mFR) will be evaluated in Modules 2 and 3, and the ASA24 food record and the image-assisted ASA24 recall will be evaluated only in Module 3. Total energy intake, macronutrient and dietary fiber intake data are the main outcomes for validity testing compared against measures of actual intake. Acceptability will be determined from feedback surveys.

This phase II trial compares the effect of encorafenib, binimetinib, and nivolumab versus ipilimumab and nivolumab in treating patients with BRAF- V600 mutant melanoma that has spread to the brain (brain metastases). Encorafenib and binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Ipilimumab and nivolumab are monoclonal antibodies that may interfere with the ability of tumor cells to grow and spread. This trial aims to find out which approach is more effective in shrinking and controlling brain metastases from melanoma.

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.

The objective of the rFVIIa for Acute Hemorrhagic Stroke Administered at Earliest Time (FASTEST) Trial is to establish the first treatment for acute spontaneous intracerebral hemorrhage (ICH) within a time window and subgroup of patients that is most likely to benefit. The central hypothesis is that rFVIIa, administered within 120 minutes from stroke onset with an identified subgroup of patients most likely to benefit, will improve outcomes at 90 days as measured by the Modified Rankin Score (mRS) and decrease ongoing bleeding as compared to standard therapy. FASTEST Part 2 is an extension of the FASTEST Trial where the subgroups include those treated within 2 hours with a positive spot sign on a baseline CT angiogram or patients treated within 90 minutes of stroke onset, with or without a positive spot sign.

The significance of developing a safe and effective therapy for aneurysmal subarachnoid hemorrhage (aSAH) patients suffering cerebral vasospasm (CVS) cannot be overstated. Vasospasm - a clamping down of normal arteries in the days following rupture - remains incredibly challenging to treat.1,2 Current drugs and minimally invasive surgical therapies are helpful, yet woefully insufficient. Symptomatic cerebral vasospasm afflicts about 30% of aneurysmal subarachnoid hemorrhage patients and nearly half will go on to suffer a stroke, despite aggressive medical care.1-3 The autonomic nervous system is a balance between sympathetic (fight or flight) and parasympathetic (rest and digest) influence with sympathetic overactivity and inflammation shown to play an important role in the development and severity of cerebral vasospasm.4,5,17-20 Prior studies of autonomic nervous system neuromodulation highlight its promise as a promising potential avenue to improve morbidity and mortality from CVS in aSAH.6-15 Despite progress, continued high levels of CVS morbidity and mortality stress the urgent need for exploration of neuromodulation therapy. In this proposal, the study team will modulate the autonomic nervous system function in aSAH patients using transcutaneous vagal nerve stimulation (tVNS). tVNS involves placement of a stimulation electrode on the external ear to non-invasively stimulate a branch of the vagal nerve and increase parasympathetic influence. This device has FDA approval for epilepsy and cluster headache. The study hypothesis is that neuromodulation of the autonomic nervous system with tVNS (increasing parasympathetic influence) reduces sympathetic overactivity and inflammation in aSAH resulting in decreased morbidity of CVS.

This phase III trial compares the effectiveness of rituximab to mosunetuzumab in treating patients with follicular lymphoma with a low tumor burden. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Mosunetuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. It is not yet known if giving rituximab or mosunetuzumab works better in treating patients with follicular lymphoma with a low tumor burden.
