Study Comparing Intravenous (IV)/Subcutaneous (SC) Risankizumab to IV/SC Ustekinumab to Assess Change in Crohn's Disease Activity Index (CDAI) in Adult Participants With Moderate to Severe Crohn's Disease (CD)

Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. This study will evaluate how well risankizumab works compared to ustekinumab. This study will assess change in Crohn's Disease Activity Index (CDAI). Risankizumab is an investigational drug being developed for the treatment of Crohn's Disease (CD). Ustekinumab is an approved drug for the treatment of moderate and severe CD. Participants are randomly assigned to one of the three treatment groups. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to ustekinumab. Around 508 adult participants with moderate to severe CD will be enrolled in approximately 307 sites worldwide. In Part 1, participants assigned to risankizumab will receive intravenous (IV) doses of risankizumab at Week 0, 4,8 and subcutaneous (SC) doses every 8 weeks thereafter through Week 48. Participants assigned to ustekinumab will receive intravenous (IV) dose of ustekinumab at Week 0 and subcutaneous (SC) doses every 8 weeks thereafter through Week 48. In Part 2, participants who received risankizumab in Part 1 and completed the Week 48 visit will continue to receive SC risankizumab for up to an additional 220 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Comparing Over the Counter Pain Medicines for Discomfort in Crohn's Disease (AVID-CD)

The purpose of this pilot study is to prepare for a larger study that will compare the effectiveness and safety of two common pain medications, ibuprofen and acetaminophen, to help treat period cramps in women with Crohn's disease. The goal of this study is to identify any challenges in running a larger study. The investigators will track how many people sign up for the study, how well participants follow the study plan, how many people stay in the study, and whether they are able to complete all the study activities, such as taking the medication, submitting samples, and filling out surveys. During the study, participants will undergo a screening visit that includes a blood draw, physical exam, pregnancy test, stool testing, and complete surveys about Crohn's disease and menstrual cycles. Once this visit is complete, the rest of the study will occur at home. Participants will be assigned to take either ibuprofen or acetaminophen to help treat period cramps for four menstrual cycles in a row. Participants will take ibuprofen for two cycles and acetaminophen for two cycles. Participants will know which medication is being taken at any given time, but the order in which they take the medications will be randomly assigned. Before each menstrual cycle, participants will submit a stool sample and fill out a short (\<1 minute) electronic survey. When participants develop period cramps, they will take the assigned medication for three days and fill out short (\<1 minute) electronic surveys about their cramps. After participants finish taking the medication for three days, they will submit another stool sample and fill out two more short (\<1 minute) electronic surveys. After have completing this process for four menstrual cycles, a remote interview with a researcher to give feedback on the study will be conducted.

Zymfentra (Infliximab-dyyb) REal World Cohort STudy

The goal of this observational study is to learn about how effective Zymfentra (IFX=dyyb) is when treating patients with Crohn's disease (CD) and ulcerative colitis (UC) Does Zymfentra lead to a reduction in symptoms at intervals throughout one year? Participants being prescribed Zymfentra (IFX-dyyb as part of their regular medical care for CD or UC will answer online survey questions about their bowel habits for 1 year.

Universal CAR-T Cell Injection Targeting CD19/BCMA in Patients With Inflammatory Bowel Disease

This is an open-label, Phase I, investigator-initiated trial (IIT) designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of RD06-05 in patients with moderate-to-severe ulcerative colitis (UC) and Crohn's disease (CD). The enrolled population consists of patients with refractory moderate-to-severe inflammatory bowel disease who have received multiple lines of biologic therapy. Two cohorts are established in the study to explore the optimal biological dose (OBD) for each indication: Cohort 1: Ulcerative Colitis Cohort Cohort 2: Crohn's Disease Cohort The study presets 3 dose groups, which are 3, 6, and 10×10⁶ CAR+T cells/kg respectively. The initial dose group is 3×10⁶ CAR+T cells/kg (Dose Group 1), and dose de-escalation or escalation may be conducted based on the assessment of the Safety Review Committee (SRC). It is expected that no more than 9 patients will be enrolled in each cohort.

A Study of Vedolizumab in Children and Teenagers With Moderate to Severe Crohn's Disease (CD)

Vedolizumab is a medicine that helps to reduce inflammation and pain in the digestive system. In this study, children and teenagers with moderate to severe Crohn's disease will be treated with vedolizumab. The main aim of the study is to check if participants achieve remission after treatment with the vedolizumab. Remission means symptoms improve or disappear and an endoscopy shows no signs of inflammation. Participants will receive 3 infusions of vedolizumab over 6 weeks. Then, those who have a clinical response will receive either a high dose or low dose of vedolizumab once every 8 weeks. They will receive the same dose every time.

Clinical Study of the Efficacy, Safety, Pharmacokinetics, Pharmacodynamics, and Immunogenicity of BCD-261 in Subjects With Moderate to Severe Active Crohn's Disease

The aim of the study is to evaluate the efficacy, safety, pharmacokinetics, pharmacodynamics and immunogenicity of study drug (BCD-261) in comparison with placebo and to characterize the dose-response relationship in patients with moderate to severe active Crohn's Disease. The study will be conducted in a population of male and female subjects ≥18 years and ≤75 years with moderate to severe active Crohn's Disease and an inadequate response to prior treatment with glucocorticoids, immunosuppressants, or biologics/targeted immunosuppressants.
