Longitudinal Immunophenotyping of Patients With Inflammatory Bowel Disease

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.

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 Study of Vedolizumab in Adults With Ulcerative Colitis (UC) or Crohn's Disease (CD) 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.

A Study to Learn More About How Risankizumab Works in Young Participants With 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 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.

Study of Advanced Therapies for the Treatment of Adult Participants With Moderately to Severely Active Crohn's Disease or Ulcerative Colitis

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.

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.

Hyperbaric Oxygen Therapy for Ulcerative Colitis (HBOT-UC)

Chronic intestinal hypoxia and accompanying mucosal inflammation is a hallmark of ulcerative colitis (UC). Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen under increased atmospheric pressure to increase tissue oxygenation. Two small prospective randomized controlled trials have demonstrated that the delivery of HBOT to UC patients hospitalized for acute moderate to severe flares results in improved remission rates and avoidance of in-hospital progression to biologics, small molecules, or colectomy. In this larger trial the study aims to confirm the treatment benefits of HBOT for hospitalized UC patients and study the immune-microbe mechanisms underpinning treatment response.
