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.

An Open-Label, Proof of Consent Study of Vorinostat for the Treatment of Mdoerate-to-Severe Crohn s Disease and Maintenance Therapy With Ustekinumab
Background: Crohn s disease (CD) is an inflammatory bowel disease. It causes inflammation of the gut. Symptoms may include diarrhea, abdominal pain, fatigue, weight loss and malnutrition. CD has no cure, but symptoms can sometimes be controlled with medicine. Researchers want to see if it is safe to treat CD with the medicine vorinostat. It is thought that vorinostat may reduce the inflammation process of CD. This may then help to relieve symptoms of CD. Participants who respond to Vorinostat will be invited to an extension phase of treatment with Vorinostat and possibly a maintenance treatment using Ustekinumab. Objectives: To see if vorinostat is safe for people with moderate-to-severe CD. To see if it is safe for people with moderate-to-sever CD to receive maintenance therapy using Ustekinumab after successful treatment of Vorinostat. Eligibility: Adults 18-65 with moderate-to-severe CD that medicine is not controlling. Design: Phase I is screening. It may last 120 days. Participants will have: Physical exam Medical history Tests of blood, urine, and stool samples Heart test Questionnaires Tuberculosis skin test They may have a colonoscopy and lymphapheresis collection. These will be explained in a separate consent. They will keep a diary of symptoms. Phase II is treatment using Vorinostat. It will take 12-13 weeks. Participants will take the study drug by mouth twice daily for 12 weeks. They will get a weekly phone call to talk about how the drug makes them feel. They will have blood taken regularly. Every 4 weeks, they will have a check-up that will repeat some screening tests. Phase III extension treatment of Vorinostat for an additional 6 months for those who respond to vorinostat and it is safe for them to continue treatment. Participants will continue to receive weekly calls to talk about how the drug makes them feel. They will have blood taken regularly. Every 3 months, they will have a check-up that will repeat some screening tests. Phase IV: is maintenance therapy for 2 years with Ustekinumab. Participants will receive a one time loading dose of ustekinumab, and then will receive the approved maintenance dose once every 8 weeks, at which time they will return to the NIH Clinical Center for evaluation. The participant will get a phone call 3 days after each dose and again 2 weeks later to see how the drug makes them feel. After two years of receiving treatment with ustekinumab the participant will have an end of study visit, where some of the screening tests, including a colonoscopy, will be repeated.

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.

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.
