Filter by:This study aims to investigate if MR Enterography (MRE) improves the ability to predict which Crohn's disease patients will relapse quickly (disease comes back) after stopping biologic medication. MRE is a safe MRI scan of the bowel, widely used in Crohn's disease patients.
The main aim of this study is to learn how the body of a child or teenager with moderately to severely active ulcerative colitis (UC) or Crohn's disease (CD) processes vedolizumab (pharmacokinetics) given just under the skin subcutaneously (SC). The participants will be treated with vedolizumab for up to 34 weeks. During the study, participants will visit their study clinic several times.
The goal of this prospective, multicenter, open-label, randomized controlled, non-inferiority trial is to test efficacy and safety of formulation switching between subcutaneous (SC) infliximab and intravenous (IV) infliximab in patients with moderately to severely active Crohn's disease (CD). The primary endpoint of this study is deep remission at week 54. The main questions this study aims to answer are: Question-1) Is maintenance therapy with SC infliximab (120mg every 2 weeks) non-inferior to IV infliximab (5mg/kg every 8 weeks) in terms of deep remission at week 54? Question-2) Is maintenance therapy with SC infliximab (120mg every 2 weeks) non-inferior to IV infliximab (10mg/kg every 8 weeks) in terms of deep remission at week 54?
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 risankizumab subcutaneous (SC) induction treatment is in treating moderately to severely active CD in adult participants. Risankizumab is an approved drug for adults with CD. This study comprises of a Period A and a Period B. In Period A, participants are placed in 1 of 2 groups to receive either risankizumab SC or Placebo. In Period B, based on response, participants will receive risankizumab SC Dose B or Placebo. Participants who do not have improvement in CD symptoms at Week 12 will receive risankizumab SC Dose C and participants with worsening CD symptoms in period B will receive risankizumab SC. Approximately 276 adult participants with a diagnosis of moderately to severely active CD will be enrolled in approximately 250 sites globally. Participants will receive SC induction treatment of risankizumab or matching placebo for up to 24 weeks in Period A and B. The duration of the study will be approximately 49 weeks.
The purpose of this study is to measure the changes in small bowel uptake of radioligand [11C]AZ14132516 after IV administration of a single dose of AZD7798 in healthy participants and participants with Crohn's disease. Study details include: - The study duration will be variable (adaptive design). - There will be 5 in-person study visits: 1 screening visit, 1 visit for the baseline PET examination, 1 residential (24h) visit for AZD7798 administration and 2 visits for repeated PET examinations. There will be a final follow-up virtual visit (telephone call).
The main aim of this study is to learn about the effect of treatment with vedolizumab IV (vedolizumab) together with adalimumab or vedolizumab together with ustekinumab in adults with moderate to severe Crohn's Disease, and the effect of treatment with vedolizumab alone, after the dual targeted treatment. The study is conducted in two parts. In Part A, participants will receive the dual targeted treatment (vedolizumab together with either adalimumab or ustekinumab). In part B, participants will receive vedolizumab only. Part B will include participants who responded to the treatment in Part A. Each participant will be followed up for at least 26 weeks after the last dose of treatment.
M-TECCU is a study: multicenter, randomized and open. It consists of two parallel groups to compare the efficacy of the TECCU web-based telemonitoring system to achieve and maintain activity remission in patients with moderate-high complexity inflammatory bowel disease compared to usual clinical practice.
Crohn's disease (CD) is an incurable chronic inflammatory disorder of the gastrointestinal tract. This study will assess how safe and effective upadacitinib is in treating moderately to severely active CD in real world. Adverse events and change in disease activity will be assessed. Upadacitinib is a drug approved for the treatment of CD. All study participants will receive upadacitinib as prescribed by their study doctor in accordance with approved local label. Approximately 240 participants will be enrolled in Japan. Participants will receive upadacitinib as prescribed by their physician according to their routine clinical practice and local label. Participants will be followed for up to 64 weeks. There is expected to be no additional burden for participants in this trial. Study visits may be conducted on-site or virtually as per standard of care.
Inflammatory Bowel Diseases (IBDs), including ulcerative colitis and Crohn's disease (CD), constitute a group of debilitating chronic diseases that profoundly impact patient quality of life and incurs large costs in terms of treatment and lost productivity. Incidence of IBD is rising worldwide, and there is a pressing clinical need for development of new therapies. Discovery and development of effective therapies to treat IBDs depend first on a better understanding of the underlying mechanisms, including how proinflammatory cells proliferate unchecked. It has been established that the cytokine interleukin (IL)-23 plays a pivotal role in IBD pathophysiology and antibodies targeting IL-23 are currently in late stage development for the treatment of both CD and ulcerative colitis (UC). IL-23 is part of the IL-12 family of cytokines (which includes IL-12, IL-27 and IL-35). The p40 subunit is shared among IL-23 and IL-12; the p19 subunit is unique to IL-23. Thus far, the efficacy of selective anti-IL-23 blockade (via anti-p19 antibodies) appears 5-10% better with respect to clinical and endoscopic outcomes than targeting both IL-23 and IL-12 using anti-p40 antibodies. Understanding the effects of IL-23 (and IL-12) in IBDs requires identification of the most relevant immune cells that respond to these cytokines. One likely cell type controlled by the IL-23 pathway are innate lymphoid cells (ILCs). ILC3s (a subset of ILCs) are dominant in healthy intestinal tissue and capable of producing IL-22 which maintain intestinal epithelial homeostasis. Disturbances in the amounts of IL-22 caused by changes in the stimulatory cytokine IL-23 in tissues, may therefore cause inflammatory responses. IL-23 may facilitate the IL-12-induced shift of ILC3s to ILC1s which are contributing to the disease-causing chronic inflammation. The DIVE 23 project is designed to understand the role of IL-23 in human IBD, in particular CD. It is hypothesized that IL-23R+ cells in the gut, are drivers of chronic inflammation in CD and determine the impact of IL-23 inhibition. To this end the investigators plan to extensively characterize the IL-23-responsive cell populations in inflamed and non-inflamed intestinal tissues of CD patients with postoperative recurrence in order to identify IL-23-responsive immune cell populations that are associated with disease activity. Patients will be treated in routine medical practice with biological agents and will undergo a second ileocolonoscopy 12-16 weeks later to investigate the impact of the different interventions on the mucosal immunology driving CD.
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. Around 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.
