Ulcerative Colitis

Background: Inflammatory bowel disease (IBD) is a term used to describe disorders that cause long-term inflammation in the digestive tract. Symptoms include stomach pain, diarrhea, and bleeding. Crohn's disease and ulcerative colitis are the 2 main types of IBD. Researchers want to conduct a natural history study to learn more about whether genetic factors can cause IBD; how immune cells contribute to IBD; and how diet, drugs, and disease affect those cells. Objective: To better understand IBD over time. Eligibility: Adults aged 18 to 85 years with Crohn's disease, ulcerative colitis, or another IBD. Their healthy relatives are also needed. Design: Affected participants will have clinic visits every 6 months for 3 years. Once a year, they will have these procedures: A physical exam with blood and stool samples. Ultrasound of the abdomen. A wand will be rolled over the skin. It uses sound waves to capture images of the intestines. Magnetic resonance imaging (MRI) scan. They will lie on a table that slides into a tube. Magnetic fields will capture images of the intestines. Colonoscopy. A long, flexible tube with a video camera will be inserted into the rectum to view the entire colon. Up to 12 tissue samples may be taken. Upper endoscopy, for those with Crohn's disease. A long, thin tube with a camera will be inserted through the mouth and into the first part of the small intestine. Up to 12 small tissue samples may be taken. Questionnaires. Participants will answer questions about their disease and their diet. Midyear visits will include a physical exam, blood and stool collection, ultrasound, and questionnaires Healthy relatives will have 1 blood draw for genetic tests.

Crohn's disease (CD) and Ulcerative colitis (UC) are 2 types of inflammatory bowel diseases which cause long-lasting, severe inflammation (redness, swelling) in the digestive tract. CD can affect any part of the digestive tract causing many different symptoms including belly pain, diarrhea, tiredness, and weight loss. UC affects the lining of the rectum and colon (large intestine) and can cause bleeding, belly pain, and diarrhea. This platform basket study will evaluate how safe and effective advanced therapies are in adults with moderately to severely active Crohn's Disease (CD) or Ulcerative Colitis (UC). This study currently includes 2 substudies evaluating different treatments in participants with CD or UC. Substudy 1 will evaluate the combination of risankizumab and trosunilimab (ABBV-466) and Substudy 2 will evaluate the combination of risankizumab and ABBV-701 (ABBV-7066). When adult participants with moderately to severely active CD or UC join the study, they will undergo a 2-step randomization within CD and UC substudies, respectively. The first unblinded randomization will assign participants into a substudy, and the second blinded randomization will assign participants to a treatment arm within the assigned substudy. Approximately 100 adult participants will be enrolled per treatment arm across both substudies at approximately 400 sites worldwide. There may be higher treatment burden for participants in this trial compared to their standard of care treatment without participating in this study. 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, stool tests, endoscopies, checking for side effects and completing questionnaires and a daily diary.

The purpose of this protocol is to evaluate the efficacy of MK-8690 in participants with moderately to severely active ulcerative colitis. The primary hypothesis is that MK-8690 is superior to placebo with respect to the proportion of participants achieving clinical remission per Modified Mayo Score at Week 12.

This research is studying whether changing an individual's behaviors may have an impact as a treatment or outcome for inflammatory bowel disease. This research will increase the understanding of the role of a self-management program in improving health and health-related quality of life for patients with inflammatory bowel disease. The study team hypothesizes: * the study will achieve a recruitment rate of 10 participants every 3 months * 70% participant retention at 24 weeks * 70% outcome data collection * 70% intervention completion * high acceptability

This is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics and clinical efficacy of ISM5411 in adult patients with active ulcerative colitis.

This is a Phase 2, multicenter, proof-of-concept platform study in adult participants with moderately to severely active ulcerative colitis (UC). The primary goal of the study is to assess the efficacy and safety of multiple interventions following intravenous (IV) induction and subcutaneous (SC) maintenance treatment.

Ulcerative colitis (UC) is a disease that causes long-term inflammation in the digestive tract, and many people with this condition require surgery to remove the colon and create a new J-pouch for stool. Some patients develop a problem called pouchitis, where this pouch becomes inflamed. Current treatments are limited, and there are no known ways to prevent pouchitis from starting. This study is being done to find out if a natural mineral supplement called Aquamin® can help reduce inflammation and protect the gut lining in people with a J-pouch, and may reduce the risk of pouchitis. By understanding whether Aquamin® is safe and helpful, the study team hopes to find a new and better way to prevent inflammation and improve the long-term health of people with UC.

The purpose of this study is to evaluate the efficacy of RO7837195 compared with placebo in participants with moderately to severely active ulcerative colitis for whom prior treatment with conventional and/or advanced therapies has failed.

Ulcerative Colitis (UC) and Crohn's Disease (CD) are long-term conditions in the gut that can cause diarrhea, swelling (inflammation), bleeding from the anus, and belly pain. The main aim of this study is to check for how many participants with UC and CD signs and symptoms disappear after 3.5 months (14 weeks) of treatment with Vedolizumab (this is called remission). Participants will be treated with Vedolizumab for approximately 1 year (50 weeks). During the first 1.5 months (6 weeks), participants will receive Vedolizumab as an infusion in the vein (called intravenously). After this, participants will receive Vedolizumab as an injection under the skin (called subcutaneously) for the rest of the treatment. Participants for whom the treatment does not seem to work well after 3.5 months (14 weeks) will stop treatment with Vedolizumab and can change to another treatment and also there will be additional required visits at 6 months (26 weeks) and at 1 year (52 weeks). All participants will be checked again 4.5 months (18 weeks) after their last treatment with Vedolizumab. During the study, participants will visit their study clinic several times.

Ulcerative colitis (UC) is a type of inflammatory bowel disease that causes inflammation and bleeding from the lining of the rectum and colon (large intestine). This study will assess how Risankizumab moves through the body as well as how safe and effective it is in treating pediatric participants with moderate to severely active UC. Adverse events and change in disease activity will be assessed. Risankizumab is an approved medication for moderate to severe UC in multiple countries and is being developed for the treatment of UC in pediatrics. This study is comprised of 3 cohorts that may participate in 3 substudies (SS). Cohort 1 will enroll participants with ages from 6 to less than 18 years. Cohort 2 will enroll participants with ages from 2 to less than 6 years. Cohort 3 will enroll participants with ages from 2 to less than 18 years. SS1 is an open-label induction period where participants will receive a weight-based induction regimen of risankizumab. SS2 is a double-blind maintenance period where participants will be randomized to receive 1 of 2 doses of weight-based maintenance regimen of risankizumab. SS3 is an open-label extension period where participants will receive risankizumab based off of their response in SS2. Around 120 pediatric participants with UC will be enrolled at around 80 sites worldwide. Participants in SS1 will receive risankizumab intravenously during the 12-week induction period. Participants in SS2 will receive risankizumab subcutaneously during the 52-week randomized maintenance period. Participants in SS3 will receive risankizumab subcutaneously during the 208-week open label period. Participants will be followed-up for approximately 140 days. 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.

Ulcerative Colitis (UC) is a chronic Inflammatory Bowel Disease characterized by chronic inflammation of the colon. Composition of gut microbiota of UC patients is abnormal (dysbiosis). Ulcerative Colitis patients have an increased risk of Clostridioides difficile infection (CDI) and CDI complications (colectomy, death, recurrence). The reason for this increased risk in IBD patients is not fully understood. The decrease in the proportion of secondary bile acids, induced by microbiota dysbiosis in patients with UC could favor C. difficile infection. The main objective of the study is to describe the composition of bile acids (primary and secondary) in children followed for UC during relapse with or without CDI and to compare it to children with UC in remission and healthy controls. The composition of fecal microbiota will be also describe to correlate dysbiosis and bile acid abnormalities. And finally some fecal biomarkers will be study : short chain fatty acids, metabolic pathway of Tryptophan, and fecal Calprotectin.

More older people (more than 65 years of age) around the world are getting Ulcerative Colitis (UC) or Crohn's Disease (CD). This is happening because people are living longer and because more people overall are developing UC or CD. Medicines that treat UC/CD, however, might make it easier for older adults to get infections. The main aim of this study is to learn if there is a difference in the number and type of infections in older people when treated with either ENTYVIO or other advance medicines (TNF-alpha inhibitors or ustekinumab) that reduce swelling and pain by blocking a chemical in the body (called TNF-alpha). The study will include people aged 65 years and older UC or CD who used either ENTYVIO with ustekinumab or a TNF-alpha inhibitor between 2016 and 2025. Data will be collected from existing Medicare databases.

The main purpose of this study is to show whether in these individuals, treatment with both mirikizumab and tirzepatide, compared with treatment with mirikizumab and placebo, leads to decrease or disappearance of UC symptoms, and loss of at least one-tenth of the overall body weight. Participation in this study will last up to 61 weeks, including 52 weeks of treatment.

The main purpose of this study is to evaluate the long-term efficacy of mirikizumab in pediatric participants with ulcerative colitis (UC) or Crohn's disease (CD). The study will last about 172 weeks and may include up to 44 visits. Additional treatment may be available to participants via a Continued Access Period.

The purpose of this research study is to test the efficacy and safety of the study intervention, CurQD or placebo (non-active pill), in combination with vedolizumab prescribed as standard of care for patients with ulcerative colitis (UC)..

The main aim of this study is to learn about medical problems (adverse events) if vedolizumab subcutaneously (SC) is given to a child or teenager with UC or CD for a long time. Other aims are to understand if the long time use of vedolizumab SC has an impact on the time period until hospital visits because of bowel swelling (inflammation) are needed and has an impact on the quality of life of children and teenagers who received vedolizumab SC. In this study, participants who responded well to the treatment with vedolizumab SC in the parent study (VedolizumabSC-3003 \[NCT06100289\]) will continue to be treated with vedolizumab SC. Participants who did not respond well to the treatment with vedolizumab SC in the parent study or who received corticosteroids in the last 4 weeks of the parent study will not receive vedolizumab SC in this study but will be followed for up to 2 years after the last treatment with vedolizumab SC in the parent study. During the study, participants will visit their study clinic several times.

Ulcerative colitis (UC) is a type of inflammatory bowel disease that causes inflammation and bleeding from the lining of the rectum and colon (large intestine). This study will assess the change in disease activity of risankizumab treatment in adult participants with moderate to severe UC in real-world clinical practice. Risankizumab is an approved drug for treating participants with ulcerative colitis. Approximately 200 participants who are prescribed risankizumab by their physician in accordance with local label will be enrolled in approximately multiple sites across Germany and Austria. Participants will receive risankizumab as prescribed by their physician according to their routine clinical practice and local label. Participants will be followed for up to 52 weeks. There is expected to be no additional burden for participants in this trial. Participants will attend regular visits during the study at a hospital or clinic according to their routine clinical practice.

The bidirectional effects between psychological distress and inflammatory bowel disease (IBD) activity mean that not only does increased IBD activity trigger psychological distress, but psychological distress triggers increased IBD activity (i.e., gut-brain interaction). Comorbid psychological distress is linked to increased health resource utilization and poor health-related quality of life (HRQoL). This has prompted calls for integrating psychological care into IBD practice with restoration of quality of life as a clinical target of IBD management alongside endoscopic healing. The IBD Social Cognitive Model (IBD SCM) posits that patient psycho-behavioral modifiers contribute to IBD outcomes and not disease modifiers alone. While a co-localized gastro-psychologist in an IBD medical home is an emerging mode of delivering psycho-behavioral care among people living with IBD, access and scalability of this form of support is not yet widespread, particularly in resource-limited settings. Though many people with IBD have significant psychological distress, mental health care is underutilized with cost cited as a barrier. The emergence of digital interventions in clinical practice presents an opportunity to address access, scalability, and cost barriers. However, current testing of digital interventions to address gut-brain interactions (digital mind-body intervention, DMBI) among people with IBD involves mostly women with high educational attainment who have full time employment and do not receive social service benefits. Individuals with limited resources and those from racial and ethnic minority groups (e.g. Black, Hispanic) often have socioecological factors, such as healthcare access and mental health stigma, that impede their use of psycho-behavioral resources. DMBI development informed by participatory research approaches are, therefore, critical to facilitate equitable engagement and utilization. Beneficial effects of psycho-behavioral treatment among people with IBD are strongest for those who have psychological distress and for acceptance, mindfulness, and values-based approaches. Although high quality evidence demonstrates psychological improvement with DMBI in IBD, feasibility and acceptability of applying DMBI to IBD patients from racial and ethnic minority groups is lacking.

This phase Ib trial studies the side effects of nivolumab and to see how well it works alone and in combination with other treatments, such as ipilimumab, cabozantinib, platinum containing therapy, and fluoropyrimidine, in treating patients with autoimmune disorders and cancer that has spread from where it first started (primary site) to nearby tissue, lymph nodes, or distant parts of the body (advanced), to other places in the body (metastatic) or cannot removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib blocks certain proteins, which may help keep tumor cells from growing. It may also prevent the growth of new blood vessels that tumors need to grow. Cabozantinib is a type of tyrosine kinase inhibitor and a type of angiogenesis inhibitor. Chemotherapy drugs, such as platinum containing therapies and fluoropyrimidine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab alone and in combination with other treatments, including ipilimumab, cabozantinib, platinum containing therapy, or fluoropyrimidine, may be safe, tolerable, and/or effective in treating patients with autoimmune disorders and advanced, metastatic, or unresectable cancer.

The main purpose of the study is to evaluate the effectiveness and safety of LY4268989 when given with mirikizumab compared to mirikizumab alone in adult participants with moderately to severely active ulcerative colitis (UC). Study participation will last approximately 118 weeks, including 104 weeks of treatment and may include up to 21 visits.

Ulcerative colitis is a long-lasting condition that causes swelling and sores in the large intestine. This study tests whether a small device placed under the skin can help reduce bowel urgency in people with ulcerative colitis. The investigational device sends mild signals to a nerve near the tailbone. It is placed during a same-day procedure.

The purpose of this study is to evaluate association between ozanimod exposure during pregnancy and subsequent maternal, fetal, and infant outcomes.

The treatment duration may be up to 280 weeks including: * 40 weeks in Pivotal Maintenance Sub-Study * 240 weeks in OLE Sub-Study The total number of on-site visit will be up to 32: * 21 visits in the Pivotal Maintenance Sub-Study. * 11 visits in the OLE Sub-Study.

The aim of this study is to evaluate the efficacy, safety, tolerability, and pharmacokinetics (PK) of filgotinib as a treatment for UC in children and adolescents aged from 8 to less than 18 years. Approximately 80 subjects from 8 to \<18 years of age with moderately to severely active UC, including a minimum of 8 subjects from 8 to \<12 years of age, will be enrolled in this study. During the study, eligible subjects will take the investigational product (IP) on-site at Week 4, Week 10, and Week 22 (in the morning; with or without food). On all other days, subjects will take IP at home (in the morning; with or without food). Subjects who do not achieve mMCS remission and/or MCS response at Week 10 will continue with induction treatment until Week 22. Subjects who do not achieve PUCAI remission at Week 22 will be permanently discontinued from the study. Subjects will all receive a filgotinib dose targeting the same systemic exposure as that observed in adults with UC treated with 200 mg q.d.
