The goal of the Precision Diagnosis in Inflammatory Bowel Disease, Cellular Therapies, and Transplantation (PREDICT) trial is to apply a systems-biology approach to enable precision diagnostics for the key immunologic outcomes for patients with Inflammatory Bowel Disease, Cellular Therapeutics and Transplantation. This approach will deepen the understanding of the molecular mechanisms driving auto- and allo-immune diseases and serve as a critical platform upon which to design evidence-based treatment paradigms for these patients. This research study will examine the immunology of auto- and allo-immune gastrointestinal disturbances such as Inflammatory Bowel Disease (IBD), Graft-versus-Host Disease (GVHD), and Functional Gastrointestinal Disorder (FGID), as well as the immune manifestations after CAR-T and other cellular therapeutics. The Investigators seek to use blood and tissue samples in order to better understand the mechanisms driving these diseases and their therapies. The Investigators further hypothesize that longitudinal systems-based immunologic analysis will enable the patient-specific determination of the molecular evolution of IBD, GVHD and the response to cellular therapeutics, as well post-transplant defects in protective immunity, and determine which pathways, when perturbed, can cause clinical disease. The discovery of these pathways will lead to improved diagnostic, prognostic and treatment approaches, and to personalized therapeutic decision-making for these patients.
Hypotheses: Hypothesis #1: The Investigators hypothesize that they can define the molecular mechanisms responsible for Inflammatory Bowel Disease (IBD) and gastrointestinal (GI) acute GVHD and differentiate it from other inflammatory disorders by using advanced immunologic analysis including flow cytometry, TCR deep sequencing and transcriptomics. Hypothesis #2: The Investigators further hypothesize that longitudinal systems-based immunologic analysis will enable the patient-specific determination of the molecular evolution of IBD as well as acute and chronic GVHD as well post-transplant def…
