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.

Study to Assess Change in Disease Activity of Risankizumab Treatment in Japanese Participants With Moderate to Severe Ulcerative Colitis

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 30 sites across Japan. 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 156 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.

Immune Regulation in Ulcerative Colitis or Crohn s Disease

This study will investigate in patients with Crohn s disease and ulcerative colitis how the body s immune system controls inflammation in the gastrointestinal tract (stomach and intestines)-specifically, how lymphocytes (a type of white blood cell) function in inflammatory responses. This protocol does not involve any experimental treatments. Patients between the ages of 0 and 75 years of age with Crohn s disease or ulcerative colitis or symptoms of inflammatory bowel disease may be eligible for this study. Screening tests may include the following: medical history and physical examination, routine blood tests, examination of stool specimens, X-rays such as barium enema or upper GI series, proctosigmoidoscopy, colonoscopy, gastroduodenoscopy, and small bowel biopsy. Participants will receive medical treatment according to the best generally accepted measures for treating Crohn s disease or ulcerative colitis. This may include anti-inflammatory drugs, immunosuppressive drugs, and antibiotics to treat infections. A surgical consultation may be recommended for patients whose disease does not respond to medical treatment. If surgery to remove intestinal tissue is recommended, a qualified gastrointestinal surgeon will perform the procedure. In addition, participants may undergo the following procedures: * Blood drawing - No more than 450 milliliters (30 tablespoons, or 15 ounces) of blood will be taken from adults over a 6-week period. A maximum of 7 ml (1/2 tablespoon) of blood per kilogram (2.2. pounds) of body weight will be obtained from children within the same time period, with no more than 3 ml/kg taken at any one time. * Leukapheresis - This procedure is done to collect large quantities of white blood cells. Whole blood is collected through a needle in an arm vein, similar to donating blood. The blood is circulated through a machine that separates it into its components, and the white cells are removed. The rest of the blood is returned to the body, either through the same needle or through another needle in the other arm. * Intestinal biopsies - Intestinal tissue will be obtained during colonoscopy with intestinal biopsy in patients who require this procedure as part of their standard medical care. Patients are given a sedative to reduce anxiety, but are conscious during the procedure. A flexible tube is inserted into the rectum and large intestine, allowing the physician to see the intestinal mucosa. At various places, small pieces of tissue are plucked out.

A Study of Vedolizumab in Adults With Ulcerative Colitis or Crohn's Disease in the Community Setting

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.

Aquamin® for Prevention of Ulcerative Colitis J-Pouch-associate Intestinal Inflammation

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.

A Retrospective Study to Evaluate Treat-to-Target and Disease Modification in Adult Participants With Crohn's Disease and Ulcerative Colitis in Real World Setting

Inflammatory Bowel Disease (IBD), encompassing Crohn's Disease (CD) and Ulcerative Colitis (UC), is a chronic, relapsing, and often disabling condition characterized by inflammation of the gastrointestinal tract. A treat-to-target strategy (T2T) is recommended by international guidelines to optimize long-term outcomes in IBD. The purpose of this study is to describe the real-life implementation of T2T in IBD worldwide and the association between using a T2T strategy and disease outcomes. This is a multi-country, observational, retrospective (non-interventional) study with a cross-sectional component based upon a sample of adult participants with IBD. All objectives will be assessed for IBD and then for CD/UC separately. Primary and secondary objectives will be assessed for the overall population over the 24 months study period. As this is an observational study, enrolled participants will be managed and followed up according to the standard practice. Retrospective chart review over the 24-months from date of inclusion will allow us to collect the variables of interest by using an e-CRF. There will be no additional burden for participants in this trial. Study visits will not be required as this is a retrospective chart review.
