Volatile Organic Compounds (VOCs) in Active Inflammatory Bowel Disease

Inflammatory Bowel Disease (IBD) are chronic diseases of the gut comprising Crohn's Disease (CD) and Ulcerative Colitis (UC). The symptoms of IBD consist of diarrhea, abdominal discomfort, weight loss, fatigue and rectal bleeding. However, symptoms and treatment vary between patients. Early management of IBD can lead to better response rates and decrease the risk of irreversible bowel damage and future disease complications such as surgeries. Current clinical tools for diagnosis and or assessing progression of IBD are either invasive (colonoscopy), have low patient acceptance (fecal calprotectin) or low accuracy (C-reactive protein). The purpose of this study is to collect clinical data and samples (including blood, breath and stool) donated by patients with IBD and patients with no IBD (controls) to facilitate research that may result in the development of new non-invasive methods of diagnosing IBD and understand the progression of the disease over time in order to better manage IBD patients.

A Study of Continued Use of Guselkumab in Participants With Crohn's Disease and Ulcerative Colitis in Real World Setting

The purpose of this study is to find out how long a participant keeps taking guselkumab or continues with their treatment plan without stopping (treatment persistence) in participants with moderate to severe Crohn's disease (CD) or ulcerative colitis (UC) in real-world setting. CD and UC are inflammatory bowel diseases, a group of inflammatory conditions of the colon and small intestine.

Artificial Intelligence For Outcomes Research in Crohn's Disease: Digital Pathology Assessment of Fibrosis and Association With Patient History and Clinical Outcomes

The goal of this retrospective observational study is to learn whether artificial intelligence-based digital pathology can measure intestinal fibrosis and help identify patients with Crohn's disease who may be at greater risk of disease progression and surgery. The main questions the study aims to answer are: Does the FibroNest Phenotypic Fibrosis Composite Score \[Ph-FCS(Muc)\], measured from routinely collected ileal biopsies, reflect the severity of fibrosis assessed by a pathologist? * Is Ph-FCS(Muc) associated with Crohn's disease characteristics and history? * Can Ph-FCS help predict whether a patient will subsequently require a first ileal surgical resection for fibrostenotic Crohn's disease? Researchers will retrospectively analyze previously collected ileal biopsies and medical information from adults with Crohn's disease. Biopsy slides will be digitized and analyzed using FibroNest digital pathology, and the resulting fibrosis measurements will be compared with pathologist assessments, clinical characteristics, disease history, and subsequent clinical outcomes.

Inflammatory Biomarkers and Disease Activity in Inflammatory Bowel Disease

This study aims to evaluate the diagnostic accuracy and clinical utility of routine blood-derived inflammatory biomarker ratios in assessing disease activity among adult patients with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. Endoscopy is the standard method for evaluating mucosal inflammation in IBD, but it is invasive, costly, and inconvenient for frequent disease monitoring. Non-invasive, inexpensive laboratory markers derived from standard routine blood tests, specifically the C-reactive protein-to-albumin ratio (CAR), platelet-to-albumin ratio (PAR), neutrophil-to-lymphocyte ratio (NLR), fibrinogen-to-albumin ratio (FAR), and hemoglobin-to-CRP ratio (Hb/CRP), have shown potential in reflecting systemic and intestinal inflammation. Participants enrolled in this cross-sectional study will undergo routine clinical disease activity evaluations and standard blood tests. For patients undergoing routine colonoscopy, endoscopic disease activity scores will also be recorded. The primary goal is to determine how accurately these blood-based ratios can differentiate active IBD from disease remission, providing a simple, cost-effective tool for regular patient monitoring.

Hyperbaric Oxygen Therapy for Perianal Fistulizing Crohn's Disease Not Responsive or Intolerant to Conventional Care: HYPNOTIC Pilot Study

This study aims to test a new treatment called hyperbaric oxygen therapy (HBOT) for a severe type of inflammatory bowel disease called perianal Crohn's disease (PCD). PCD causes painful perianal infections and chronic drainage from fistula tracts, and current treatments are only moderately effective and may not be suitable for all patients. HBOT is a safe and commonly used treatment for chronic non-healing wounds and other conditions. Previous studies have suggested that HBOT may help heal fistulas in PCD patients, but these studies were small and lacked controls.

The main purpose of this study is to see how the safety and efficacy of a farnesoid X receptor (FXR) agonist (LY4395089), given together with mirikizumab compares with mirikizumab (alone) in adults with moderately to severely active Crohn's disease (CD). This study is part of the IIBD master protocol and will last approximately 62 weeks.

A Master Protocol (IIBD): A Study of Multiple Drugs in Adults With Ulcerative Colitis or Crohn's Disease

Study IIBD is a master protocol that will support a collection of individual sub studies that share key design components. Participants will be assigned to the appropriate study prior to randomization to a treatment group. The studies aim to evaluate the efficacy and safety of new treatments in adults with moderately to severely active ulcerative colitis or Crohn's disease and will last at least 62 weeks.

A Novel Remote Patient and Medication Monitoring Solution to Improve Adherence and PerSiStence With IBD Therapy

The investigators hypothesize that use of a remote monitoring digital health system that supports medication taking and monitoring of symptoms will improve adherence, clinical outcomes, and decrease healthcare utilization compared to standard care in participants with inflammatory bowel disease initiating oral or subcutaneous treatment. The investigators are conducting a 12-month, multicenter, randomized, controlled trial to assess the feasibility and effectiveness of a remote monitoring digital health system on adherence, clinical outcomes, and healthcare utilization. The investigators will address the following specific aims: 1. Compare adherence as measured by the medication possession ratio in participants using a remote monitoring digital health system compared to standard of care. 2. Compare clinical outcomes and healthcare utilization in participants using a remote monitoring digital health system compared to standard of care.

Intestinal Ultrasound Guided Management in Inflammatory Bowel Disease

This randomized controlled trial evaluates whether adding point-of-care intestinal ultrasound (IUS) to standard of care changes clinical management in patients with inflammatory bowel disease (IBD). Adult patients with Crohn's disease or ulcerative colitis undergoing colonoscopy for disease assessment are randomized 1:1 to standard of care plus IUS at every visit, or standard of care alone, and followed for 48 weeks. The primary outcome is the proportion of patients with a change in treatment.

Expanded Access to Upadacitinib

This is an expanded access program (EAP) for eligible participants. This program is designed to provide access to upadacitinib prior to approval by the local regulatory agency. Availability will depend on territory eligibility. A medical doctor must decide whether the potential benefit outweighs the risk of receiving an investigational therapy based on the individual patient's medical history and program eligibility criteria.

Lesion Size Measurement During Gastrointestinal Endoscopies

The goal of this prospective observational study is to assess the accuracy and reliability of laser readings obtained through AccuMeasure, in comparison to other measurements performed by gastroenterologists. AccuMeasure is a novel technology, that has emerged as a promising tool for measuring polyps and lesions during colonoscopies. The system employs laser-based measurements, enabling precise determination of lesion size, depth, and extent. The main hypotheses this study aims to evaluate are: * AccuMeasure technology, with its precise laser measurements, will demonstrate superior accuracy and reliability in assessing lesion size of pathologies encountered during endoscopies, when compared to other endoscopic scoring methods. * AccuMeasure measurements will show strong construct validity by correlating significantly with endoscopic subscores, symptomatic remission (CD PRO2 \<8, partial mayo score), and fecal calprotectin values.

Utility of Random Biopsies in Patients With Inflammatory Bowel Disease

The proposed study is a multicenter parallel group clinical trial that will include 821 evaluable patients per group who will be randomly assigned to either high definition white light colonoscopy (HDWLC) with targeted biopsies plus 2 random biopsies in 4 segments to assess for inflammation (limited biopsy strategy) or HDWLC with targeted biopsies plus 4 biopsies every 10 cm throughout the colon, at a minimum in all segments of the colon known to have been affected by IBD at any time, regardless of the extent of disease (random biopsy strategy). Participants will be followed until total proctocolectomy or the end of the study period to determine whether the two methods of surveillance colonoscopy are associated with detection of dysplasia or sessile serrated adenoma at follow-up colonoscopy. Follow-up via chart review may continue for up to 15 years from enrollment.
