This is a randomized, open-label study in adult patients who have completed standard first line therapy for large B-cell lymphoma (LBCL) and achieved a complete response or partial response suitable for observation, but who have minimal residual disease (MRD) as detected by the Foresight CLARITY™ Investigational Use Only (IUO) MRD test, powered by PhasED-Seq™. The purpose of the trial is to assess the efficacy and safety of consolidation with cemacabtagene ansegedleucel (cema-cel), an allogeneic CD19 CAR T product, as compared to standard of care observation. In this study, participants with MRD are randomized 1:1 to treatment with cema-cel or an observation arm. Treatment includes cema-cel following a lymphodepletion regimen of fludarabine and cyclophosphamide. Prior to August 2025, participants may also have received an anti-CD52 monoclonal antibody, ALLO-647, as part of their lymphodepletion regimen. Type: Interventional Start Date: Jun 2024 |

The Comprehensive HHT Outcomes Registry of the United States (CHORUS) is an observational registry of patients diagnosed with Hereditary Hemorrhagic Telangiectasia (HHT). The purpose of this study is to better understand HHT, the symptoms and complications it causes, and the impact the disease has on people's lives. The investigators will collect long-term information about the participant, allowing us to understand how the disease changes over time, and what factors can influence those changes. Ultimately, this should help improve treatments for the disease. Another important goal of the study is to provide a way to contact people to participate in future clinical trials and other research. The registry will be a centralized resource for recruitment for clinical trials. People in the registry will not be obligated to join any of these additional studies, but if interested, can agree to be contacted if they may be eligible for a study. Participants will: - Be asked to provide permission to collect information from their medical records, including things like demographic information, diagnosis information, family history, test results, treatment information, symptoms, complications, lifestyle and other relevant medical information. - Be asked study-related questions by phone or at a clinic visit. - Be asked study-related questions every year after enrollment for up to 10 years or until the study ends. A member of the study team will communicate with participants by phone or at clinic visits to collect information regarding any changes to their health over the previous year/s including new test results, treatment information, symptoms, and complications from HHT.

genetic variation impacts response to an FDA-approved medication commonly used to treat
type 2 diabetes called oral semaglutide (Rybelsus) and to characterize the physiological
response to a mixed meal tolerance1 expand
The goal of this research study is to evaluate the pathophysiologic mechanisms by which genetic variation impacts response to an FDA-approved medication commonly used to treat type 2 diabetes called oral semaglutide (Rybelsus) and to characterize the physiological response to a mixed meal tolerance test (MMTT) before and after a 14-day treatment with oral semaglutide. The investigators will do this by measuring factors in the blood, such as sugars, fats, metabolites, and proteins, after eating a standardized breakfast meal at the first visit and after taking 14 doses of oral semaglutide over two weeks before the second study visit. The food (mixed meal breakfast) we will be studying is specially prepared to contain a set amount of protein, carbohydrates, and fat. The investigators hypothesize that understanding how the acute biochemical response to oral semaglutide differs by genetic variation will generate insight into drug mechanisms and type 2 diabetes pathophysiology.

Vocal hyperfunction (VH) is the most commonly treated class of voice disorders by speech-language pathologists and voice therapy is the primary curative treatment. Patients and clinicians report that generalizing improved voicing into daily life is the most significant barrier to successful therapy.

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. Type: Interventional Start Date: Apr 2023 |

Spinocerebellar ataxias (SCA) are genetic neurological diseases that cause imbalance, poor coordination, and speech difficulties. There are different kinds of SCAs and this study will focus on types 1, 2, 3, 6, 7, 8, 10, 27B, and RFC1-ataxia (SCA 1, SCA 2, SCA 3, also known as Machado-Joseph disease, SCA 6, SCA 7, SCA 8, SCA 10, SCA27B, and RFC1-ataxia, also known as CANVAS). The diseases are rare, slowly progressive, cause increasingly severe neurological difficulties, and are variable across and within genotypes. The purpose of this research study is to bring together a group of experts in the field of SCA for the purpose of learning more about the disease. The research questions are: 1. How do these diseases progress over time? 2. What are the best ways to measure the progression? 3. Do some genes, other than the gene that is abnormal in these diseases, have any effect on the way the disease behaves? This is a nationwide study and the investigators expect that 1400 patients will participate all over North America. The participants will remain in the study for an indeterminate period of time, for as long as they are willing to participate. Study visits will be done every 12 months. Within the broader CRC-SCA, there is an Imaging Sub-study aiming to identify magnetic resonance imaging (MRI) markers sensitive to the onset and progression of common SCAs. To accomplish this, participants attend annual visits involving a neurological exam, surveys, a blood draw, and an MRI scan. Participants can attend visits at one of three US locations - Minneapolis, MN; Gainesville, FL; or Dallas, TX and two European locations - Paris, France and Bonn, Germany. Eligible participants must either have SCA1, 2, or 3 or have been a participant of the previous READISCA study (NCT03487367). Gene-positive participants must have a SARA score less than 10; however, there is no SARA limit for participants previously enrolled in READISCA. All participants must be 18 years or older. Gene-negative participants should be 25-65 years old. Type: Observational Start Date: Apr 2010 |
