A Study to Learn About the Effectiveness of Etrasimod in People With Ulcerative Colitis
The purpose of this real world non-interventional study is to learn about the effects of etrasimod as treatment for patients with moderate to severe ulcerative colitis. Patients will be treated according to standard of care and will only be included in the study if etrasimod is the best treatment choice according to the treating physician. Additionally, patients have to be between 18 and 65 years of age and should not have taken etrasimod in the past. All patients will be prescribed etrasimod according to standard of care. Assessments will be conducted according to standard of care with the exception of health questionnaires which will be completed by the patients online on their own device. The study duration is 52 weeks with 28 days of safety follow-up. Patients will visit their treating physician as they would if they were not enrolled in the study. During the study duration, patients will be asked to complete health questionnaires on a regular basis either on their mobile phone, tablet or computer. The effects of etrasimod will be analyzed for each patient comparing to their disease activity prior to the start of etrasimod.

Longitudinal Registry of Difficult-to-Treat Inflammatory Bowel Disease
Difficult-to-treat inflammatory bowel disease (DTT-IBD) represents a heterogeneous group of patients with treatment-refractory, structurally complicated, postoperative, perianal, pouch-related, or psychosocially complex disease. This multicentre ambidirectional observational cohort will establish a longitudinal registry of adults with inflammatory bowel disease and systematically identify patients meeting prespecified DTT-IBD criteria. Clinical data will be reconstructed retrospectively and collected prospectively using a common data dictionary, including disease phenotype, advanced-therapy exposure and failure, objective disease assessments, multidisciplinary decision-making, treatment implementation, surgery, hospitalization, and long-term outcomes. The registry will characterize the occurrence, clinical domains, treatment trajectories, longitudinal disease-control states, and outcomes of DTT-IBD. No treatment, diagnostic test, dose, surgery, or monitoring procedure will be assigned by the study. Clinical management will remain entirely at the discretion of the treating physicians and patients. The platform is designed to support prespecified nested studies addressing treatment-failure mechanisms and clinical decisions, longitudinal DTT trajectories and cumulative uncontrolled disease, and implementation of multidisciplinary care.

An Observational Study of Etrasimod in Adult Patients With Moderate to Severe Ulcerative Colitis
The purpose of this observational study is to learn about the effects of etrasimod as a treatment for adult patients with moderate to severe ulcerative colitis. Patients will be treated according to standard of care and will only be included in the study if etrasimod is the best treatment of choice according to the physician and they have not previously taken etrasimod. All patients will be prescribed etrasimod according to standard of care. Tests and doctor visits will be conducted according to standard of care with the exception of health questionnaires about ulcerative colitis symptoms. These questionnaires will be completed by patients at various timepoints during the study using their mobile phone, tablet, or computer. The study is 52 weeks with 28 days of safety follow up. The effects of etrasimod will be analyzed for each patient comparing their disease activity prior to the start of etrasimod.

Confirmatory Clinical Study in Active Ulcerative Colitis
The main goal of the study is to check if MH002 works and is safe to use. In a previous study in 45 patients with Ulcerative Colitis, MH002 was found to have favorable effects. In this study, 2 different doses will be tested, and long-term treatment effects will be investigated. MH002 is a live biotherapeutic product (LBP). This is a biological medicine containing live bacteria used to restore the normal function of a gut that is damaged by ulcerative colitis (UC). Ulcerative colitis is a bowel disease that causes inflammation and sores in the gut.
