Filter by:The purpose of this study is to describe the initial response to ustekinumab induction treatment for ulcerative colitis (UC) in Japan.
The purpose of this research is to determine if different diets have different effects on the inflammation in the colon.
People with inflammatory bowel diseases (IBD) can be at higher risk of developing abnormal areas in their bowel. These abnormal areas can be due to active inflammation, healed inflammation, polyps or pre-cancerous changes ("dysplasia"). It is for this reason that people with IBD are offered periodic surveillance colonoscopy procedures to identify, characterize and where necessary remove abnormal areas or lesions from the bowel. These can be difficult to characterize correctly, which is important to make the correct endoscopic diagnosis and management plan. Technical advancements in endoscopy mean that more tools are available to identify and characterize these lesions in real time during colonoscopy. Specialists regularly performing gastrointestinal endoscopy and colonoscopy ("endoscopists") will often receive special training, both during their initial postgraduate training and through continuous professional development programs. This study aims to evaluate whether an online training platform can improve the ability of endoscopists to characterize dysplasia in IBD. The goal is to support improved decision-making during IBD surveillance, reporting of dysplastic lesions, and ultimately the care and outcomes of people with IBD.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity of MK-6194 in participants with active UC.
The purpose of this study is to characterize which patients with Crohn's disease are likely to respond to standard of care to vedolizumab therapy.
The purpose of this study is to evaluate the long-term safety and efficacy of Deucravacitinib in participants who have previously been enrolled in a Deucravacitinib Phase 2 study for moderate to severe Crohn's disease or moderate to severe Ulcerative Colitis.
This is a Phase 1b, randomized, double-blind, multicenter dose-ranging study to evaluate the safety, tolerability, and PK of NX-13. Approximately 40 subjects will be randomized in a 3:3:3:1 ratio to receive 1 of 3 NX-13 treatment regimens (NX-13 250 mg IR, 500 mg IR, 500 mg MR) (12 evaluable subjects at each of the 3 dose levels) or placebo (4 subjects), once daily for 28 consecutive days.
Given the bidirectionality between psychological distress and disease activity in inflammatory bowel disease (IBD), whereby increased psychological distress exacerbates disease activity and vice versa, psychosocial aspects of IBD care are receiving increased attention. However, proposed interventions are generally resource-intensive and have been tested in majority white populations. While people of color are an increasing segment of the IBD population, they are currently underrepresented in research studies. The purpose of this study is to evaluate the efficacy and implementation of internet-based cognitive behavioral therapy (iCBT) among IBD patients of color with elevated psychological distress.
The purpose of this study is to assess effectiveness of vedolizumab versus ustekinumab in patients with Crohn's disease and vedolizumab versus tofacitinib in patients with ulcerative colitis, after non-response to anti-tumor necrosis factor (TNF) medications, using data from two existing cohorts.
Specific Aim 1: Characterize the effects of vitamin D treatment on expression of α4β7 on B cells in patients with inflammatory bowel disease (IBD). Specific Aim 2: Determine the effects of vitamin D treatment on fecal immunoglobulins, percentage of Ig-coated gut bacteria, gut microbiome composition (global and bound by immunoglobulins) in patients with IBD and the association of these parameters with change in α4β7+ B cells . Specific Aim 3: Compare BCR repertoire (BCR clonotypes, immunoglobulin heavy chain gene (IGHV), and isotype usage) between α4β7+ and α4β7- B cells in patients with IBD and identify α4β7+ BCR clonotypes associated with Ig-bound gut bacteria .
