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.

A Study to Assess Adverse Events, Change in Disease Activity, and How Intravenous and Subcutaneous Risankizumab Moves Through the Body of Pediatric Participants With Moderately to Severely Active Crohn's Disease
Crohn's Disease (CD) is a gastrointestinal disease that can cause chronic diarrhea with or without gross bleeding, abdominal pain, weight loss, and fever. This study will assess the pharmacokinetics, efficacy, and safety of risankizumab in pediatric participants with moderately to severely active CD aged 2 to \< 18 years old who have had intolerance or inadequate response to other therapies. Risankizumab is an approved drug for adults with plaque psoriasis, psoriatic arthritis, and CD and is being developed for the treatment of CD 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 induction regimen of risankizumab. SS3 is an open-label extension period where participants will receive risankizumab based off of their response in SS2. Approximately 110 pediatric participants with CD will be enrolled at around 100 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 Targeted Therapies for the Treatment of Adult Participants With Moderate to Severe Crohn's Disease
Crohn's disease (CD) is a long-lasting disease that causes severe inflammation (redness, swelling), in the digestive tract, most frequently affecting the bowels. It can cause many different symptoms including belly pain, diarrhea, tiredness, and weight loss. Treatments are available but do not work the same for all patients or may stop working over time. This study will evaluate the effectiveness and adverse events of targeted therapies (TaTs) for adult participants with moderate to severe CD. The medicines assessed in this study are risankizumab, trosunilimab, lutikizumab, and ABBV-8736. When participants join the study, they will be randomized into available study treatment groups. Adult participants with CD will be enrolled. Around 540 participants will be enrolled in the study at approximately 300 sites worldwide. Risankizumab and trosunilimab are given as an injection under the skin or as an infusion into the vein. Lutikizumab is given as an injection under the skin. ABBV-8736 is given as an infusion into the vein. 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, endoscopies, checking for side effects and completing questionnaires and a daily diary.

Crohn's Disease: Efficacy, Safety, and Pharmacokinetics of Upadacitinib in Pediatric Subjects With Moderately to Severely Active Crohn's Disease
Crohn's disease (CD) is a long-lasting disease that causes severe inflammation (redness, swelling), in the digestive tract, most often affecting the bowels. It can cause many different symptoms including abdominal pain, diarrhea, tiredness, and weight loss. This study will assess how safe and effective oral Upadacitinib is in treating moderately to severely active Crohn's Disease in pediatric participants aged 2 to 18 years old who have had inadequate response, loss of response, intolerance, or medical contraindications to corticosteroids, immunosuppressants, and/or biologic therapy. Upadacitinib (RINVOQ) is a drug approved in adults for moderate- to severely active CD and is being developed for moderate- to severely active CD in pediatric participants. This study is conducted in 2 periods: Period 1 is comprised of two phases: a 12-week open-label induction phase which means that the study doctor and participants know that participants will receive UPA Dose-A (or the adult equivalent based on body weight) followed by a 52-week double-blind maintenance phase meaning that neither the participants nor the study doctors will know which dose of upadacitinib will be given (UPA Dose B or Dose C). Period 2 is a 156-week open-label extension of Period 1. Approximately 110 pediatric participants with moderate to severely active CD will be enrolled at approximately 92 sites worldwide. Participants will receive upadacitinib oral tablets once daily or oral solution twice daily at approximately the same time each day, with or without food. Participants will have a safety follow up for 30 days after discontinuation from any time point within the study. There may be higher treatment burden for participants in this trial compared to their standard of care (due to study procedures). Participants will attend regular (weekly, monthly) 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.

A Continuation Study of TAK-279 in Adults With Ulcerative Colitis (UC) and Crohn's Disease (CD)
Crohn's Disease and Ulcerative Colitis are two types of inflammatory bowel disease (IBD), which is a serious, long-term condition in the gut (intestine) that can cause pain and swelling (inflammation) in the bowel. TAK-279 is a medicine which helps to block inflammation. This study is an extension of the parent studies, TAK-279-CD-2001 (NCT06233461), TAK-279-UC-2001 (NCT06254950) and TAK-279-CD-2003 (NCT07403968). This means that participants who responded to treatment with TAK-279 in either of the parent studies may be able to continue to benefit from the treatment in this study. The main aim of this study is to find out how safe TAK-279 is for long term use and to check if it reduces bowel inflammation and symptoms when used for a longer period of time in adults with moderately to severely active UC or CD. The participants will be treated with TAK-279 for up to 3 years (156 weeks). During the study, participants will visit their study clinic around 15 times.

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.
