Filter by:Two thirds of patients with Crohn's disease require intestinal surgery at some time in their life. Intestinal strictures, that is narrowing of the bowel due to inflammation and scarring, are the most common reason for surgery. Despite the high frequency, associated disability, and cost there are no are no treatment strategies that aim to improve the outcome of this disease complication. The STRIDENT (stricture definition and treatment) studies aim to develop such strategies.
The purpose of this study is to determine the safety profile of long-term vedolizumab IV treatment in pediatric participants with UC or CD.
Crohn's disease is a chronic inflammatory bowel disease. This disease can be treated with, among other things, biologicals such as adalimumab. Patients use adalimumab for a long time to maintain remission and to prevent relapse of the bowel inflammation. The disadvantages of this therapy are the high price and side effects (such as the higher risk of infection). Currently, adalimumab is given every 2 weeks, by injection under the skin. The optimal time between two injections has never been investigated before. Prior research in patients with rheumatoid arthritis shows that disease remission can be maintained with longer injection-intervals. Our hypothesis is that this is the same for Crohn's disease patients. Our aim is to show non-inferiority of extending the adalimumab dosing interval, under strict disease monitoring in Crohn's disease patients in sustained (>9 months) clinical remission, compared to standard care. During the trial,174 patients with stable Crohn's disease will be divided into 2 groups. One group continues adalimumab injections with the same 2-week interval. And the other group will incrementally extend the interval to 4 weeks, under strict disease monitoring. If a step-down leads to recurrence of disease activity patients will return to the preceding effective dosing interval. Thus, we will investigate whether, and for whom, it is safe to extend the adalimumab injection interval.
The goal of this study will be to assess the safety and efficacy of high-dose interval Vitamin D3 therapy in children and young adults with Inflammatory Bowel Disease being treated with serial Remicade infusions.
The overall goal of the study is to develop data that can convincingly guide clinicians on the use and efficacy of vedolizumab in patients with small bowel CD. There is an unmet need to identify response to vedolizumab in small bowel CD using objective endpoints. Current data suggest that MR enterography may meet this unmet need. There is an additional unmet need to develop predictive models incorporating both clinical and baseline radiological and endoscopic variables with higher discriminatory performance in identifying longer term clinical remission with vedolizumab. Finally, this proposal is strengthened by the exploratory studies which may identify new proteomic biomarkers that correlate with longer term radiological response with vedolizumab reflecting its latency of response. If successful, these serum biomarkers may guide a personalized approach to the treatment of small bowel CD with vedolizumab, allowing early identification of PNR, monitoring disease activity and the pharmacodynamics of vedolizumab.
The study consists of 4 sub-studies, as follows: - Sub-study 1 (Randomized, double-blind, placebo controlled study) to evaluate the efficacy and safety of risankizumab versus placebo as maintenance therapy in participants with moderately to severely active Crohn's disease (CD) who responded to intravenous risankizumab induction treatment in Study M16-006 or Study M15-991; - Sub-study 2 (Randomized, exploratory maintenance study) to evaluate the efficacy and safety of two different dosing regimens for risankizumab as maintenance therapy in participants who responded to induction treatment in Study M16-006 or Study M15-991; - Sub-study 3 (Open-label, long-term extension study) to evaluate long-term safety of risankizumab in participants who completed Sub-study 1, Sub-study 2, another AbbVie risankizumab Crohn's disease study, or participants who responded to induction treatment in Study M16-006 or Study M15-991 with no final endoscopy due to the Covid-19 pandemic. Additional objectives are to further investigate long-term efficacy and tolerability of risankizumab; - Sub-study 4 (Open-label On Body Injector (OBI) administration and long-term extension study) to evaluate patient-reported outcomes, efficacy, safety, tolerability, and pharmacokinetics of risankizumab administered via OBI in participants who are receiving maintenance treatment with risankizumab. - OL CTE to ensure uninterrupted care in accordance with local regulations until risankizumab is commercially available for participants who completed Sub-study 3, Sub-study 4.
To develop a cost-effective, individualised anti-TNF treatment strategy for patients with Crohn's disease which maximizes benefit and minimises harm. The primary objective of this study is to investigate the mechanisms that underlie primary non-response (PNR), loss of response (LOR) and adverse drug reactions (ADRs) to anti-TNF drugs in patients with active luminal Crohn's disease.
This study evaluates the safety and clinical benefits of a therapeutic approach using the cyclophosphamide (Cy) + thymoglobulin® (ATG) + granulocyte colony-stimulating factor (G-CSF) conditioning regimen followed by autologous hematopoietic stem cell transplantation (HSCT) rescue in the treatment of refractory Crohn's disease. Adverse events, and clinical and endoscopic conditions will be assessed at different short and long-term time points.
The aim of this research is to study the effects of a pomegranate juice on calprotectin levels in patients suffering of inflammatory bowel disease (IBD) in clinical remission. Fecal calprotectin levels, surrogate marker of mucosal inflammation, will be measured from baseline to 12 weeks later (end of intervention). Systemic and mucosal changes of biochemical and molecular inflammatory response markers will be also assessed.
This will be an open label multicenter study of the safety and efficacy of an active implantable VNS device in patients with Crohn's Disease.
