The goal of the DDRCC Biorepository is to collect human samples and health information to store for future research. Samples to be collected are blood, tissue (gastrointestinal, liver, pancreas and/or lymph nodes), stool, and cheek swabs. Participants may be eligible to enroll if scheduled for a clinical visit or surgical procedure during which these samples could be collected.

This study aims to evaluate the clinical development program for icotrokinra in the treatment of adult participants with moderately to severely active CD. Icotrokinra may offer additional advantages beyond injectable antibody therapies and available
oral therapies for the treatment of patients with moderate to severely active CD due to its oral route of administration, high local exposure to GI tissues, and systemic activity. Overall, the program will evaluate icotrokinra treatment in a target of 1092 participants through at least 52 weeks but participants can participate in a long-term extension for 4 years (total duration approximately 5 years).

Efficacy of the vedolizumab IV and SC formulations has been demonstrated in completed studies of adult subjects with moderately to severely active UC or CD. Clinical trial results are needed to affirm proper dosing, exposure, efficacy and safety for use of vedolizumab in pediatric patients. Subsequent to preliminary positive results from the completed pediatric phase 2, vedolizumab IV is being further evaluated in the phase 3 Studies MLN0002-3024 and MLN0002-3025 (subjects aged 2 to 17 years). Confirmatory positive results from these studies would support submission for registration of vedolizumab IV for pediatric patients. Vedolizumab SC is being evaluated in the proposed study to provide an alternative administration route of vedolizumab for maintenance treatment in the
same pediatric population

The study aims to evaluate if an experimental drug called SAR441566 can improve signs and symptoms of moderate to severe ulcerative colitis (UC). SAR441566 is a new drug that inhibits Tumor necrosis factor receptor 1 (TNFR1) signaling. This study will also help the Sponsor to understand which dose of SAR441566 is most effective and safe in participants with moderate to severe UC. To do this, 3 different doses of SAR441566 will be tested along with a placebo. The study will last about 1 year, will include about 260 adult participants across over 26 countries.

The study aims to evaluate if an experimental drug called SAR441566 can improve signs and symptoms of moderate to severe Crohn's disease (CD). SAR441566 is a new drug that inhibits Tumor necrosis factor receptor 1 (TNFR1) signaling.

To do this, 3 different doses of SAR441566 will be tested along with a placebo. The study will last about 1 year, will include about 260 adult participants across over 26 countries.

The purpose of this research study is to determine the best treatment goals for patients with active CD. Researchers are investigating how treating and monitoring CD to meet specific treatment goals will keep your disease under control (remission) and decrease complications such as hospitalizations and surgeries. Group 1 treatment goals include IUS response (if the drug is improving your CD) and IUS assessed transmural healing (healing of all bowel layers), clinical remission (normalization of CD symptoms), and biomarker remission (improvement in stool and blood tests that show inflammation). Group 2 treatment goals include clinical remission and biomarker remission. Comparing the treatment goals in these groups may inform doctors how best to manage CD in the future. Approximately 304 people will be enrolled in this study. This research study will involve receiving 300 mg of vedolizumab as an intravenous (IV) infusion into your arm at Weeks 0, 2, 6, 10, and 14, then every 4 or 8 weeks thereafter.

This study will evaluate the efficacy and safety of RO7790121 compared with placebo in patients with moderately to severely active CD. Data on currently available treatments highlights the need for new medications in addressing the high unmet need in CD. The total maximum duration of study participation for an individual is expected to be approximately 70 weeks without OLE participation. With OLE participation, treatment will continue until RO7790121 is commercially available in that region or until the Sponsor decides to terminate the study, whichever is earlier. Approximately 600 patients will be enrolled in the study.

This is a prospective, observational research study for patients with IBD under the care of a gastroenterologist provider. The objective of the Corrona Inflammatory Bowel Diseases (IBD) Registry is to create a national cohort of patients with IBD.The diseases under study include Crohn's Disease (CD), Ulcerative Colitis (UC) and Indeterminate Colitis (IC). Data collected will be used to better characterize the natural history of the disease and to extensively evaluate the effectiveness and safety of medications approved for the treatment of IBD .Approximately 10,000 patients and 150 clinical sites in North America will be recruited to participate with no defined upper limit for either target. The Corrona IBD Registry is a long-term observational study; therefore, the duration of the registry has no pre-determined stop date.
