Filter by:This study is designed to evaluate the long-term efficacy and safety of mirikizumab in participants with moderately to severely active ulcerative colitis (UC). The study will last up to 3 years. Participants who complete the 3-year study may continue to receive mirikizumab until it is (outside of this study) in their country or until they meet other discontinuation criteria.
The purpose of this study is to evaluate the safety and efficacy of Mirikizumab in participants with moderately to severely active ulcerative colitis (UC) who have had an inadequate response to, loss of response, or intolerant to conventional or biologic therapy for UC.
There is limited data to guide the use of dietary change in the management of IBD, and it can prove challenging to implement in the setting of altered anatomy, comorbid conditions, and patient compliance. Therefore there is an important need to study diet as a therapy for IBD. Here, the investigators propose a novel study to evaluate the feasibility and efficacy of the autoimmune protocol (AIP) diet in patients with active Crohn's disease (CD) and ulcerative colitis (UC).
The surgical treatment of the ulcerative colitis (UC) remains associate to a significant morbidity (up to 60%). Anastomotic fistula and pelvic sepsis are the most severe complications which could dramatically compromise the surgical issue and functional status. Thanks to the current therapeutic arsenal and the evolution of health care paradigms, the quality of life of patients plays a key role in the modern global management of these medical conditions. Biotherapies (e.g anti-TNF) are widely used to treat patients with UC. Anti-TNF and anti-integrins have an effect on the immune response and can theoretically aggravate the infectious disease. Their potential impact on postoperative complications after ileo anal anastomosis (AIA) remains debated. Very few studies have looked at other biotherapies including vedolizumab. All studies are retrospective series with small sample size. Here again the conclusion remain contradictory. Lightner et al. showed an increased risk of surgical site infection for patients preoperatively exposed to vedolizumab (37% vs. 10%, p <0.001). In a dedicated cohort to the RCH, the same author found a risk of increased pelvic abscess (31.3% vs 5.9%, NS) but the difference was not statistically significant probably for lack of power. Other studies did not find any impact of vedolizumab on the risk of postoperative complications. To clearly determine within a large prospective cohort the impact of anti-TNF agents and biotherapies on the postoperative complications seems to be essential in order to adapt and to optimize the therapeutic strategy, especially the surgical sequences, in patients with UCR whom benefit a surgery.
Rationale: Ulcerative colitis (UC) is remitting disease with a variable course. Predicting disease relapse after remission is important for the adjustment of medical treatment. Ileocolonoscopy is the best tool for doing this, but due to its invasiveness should be replaced by a method better accepted by the patient. Gastrointestinal ultrasound (GIUS) could be such a method.The PRELAPSE study will include UC patients who have been on maintenance anti-TNF therapy for at one year or more and in clinical remission for the 3 past months at least in two centres, Haukeland University Hospital and Ålesund Hospital. The infrastructure for recruiting these patients has already been established in the BIOSTOP study (Protocol ID no: HMR2016-0.6 and EudraCT (European Clinical Trials Database) no: 2016-001409-18). Objective: To study if GIUS or individual US parameters can predict endoscopic relapse at follow up examinations in a group of patients with ulcerative colitis in sustained clinical and endoscopic remission Study design: Prospective, longitudinal, explorative, observational multi-centric study for diagnostic accuracy Study population: Adult patients with histo-pathologically confirmed diagnosis of UC between 18 and 80 years of age that have entered the BIOSTOP trial (Trial number: EudraCT: 2016-001409-18) will be considered for inclusion in the proposed study. Intervention: All patients will be subjected to trans-abdominal gastrointestinal ultrasound and ileocolonoscopy. Blood and faeces samples will be collected at one time point for measuring relevant inflammatory markers. Main study parameter: Ultrasound measurements of the intestine of patients with ulcerative colitis Nature and extent of the burden and risks associated with participation, benefit and group relatedness: All patients will be examined repeatedly with gastrointestinal ultrasound (GIUS) and at certain time points with ileocolonoscopy or sigmoidoscopy. As all these procedures already are scheduled as a part of the BIOSTOP study the only extra burden for the patients will be the ultrasound examination. GIUS is a safe procedure that uses high frequency sound waves for the visualization of internal organs. The implementation of GIUS for the assessment of disease activity in UC patients might result in a reduced need for ileocolonoscopy, thereby reducing costs and the burden for patients. Compared to invasive endoscopic procedures GIUS can be performed without preparation, which is an advantage for the patients as treatment decisions can be made without delay. GIUS is also cheaper than ileocolonoscopy, causes little discomfort and has few or no complications.
Ulcerative colitis (UC) is a chronic inflammatory bowel disease associated with recurrent mucosal inflammation. Clinically, the disease is characterized by bloody diarrhea, abdominal pain, and constitutional symptoms such as fever and weight loss. Treatment strategies vary based on disease activity and target various aspects of the inflammatory cascade. Options include: anti-inflammatory drugs (mesalamine), immunosuppressive or modulatory medications (corticosteroids, thiopurines, cyclosporine) and biologic agents (Anti-TNF). Disease severity can be wide ranging, and nearly 25% of UC patients are hospitalized for acute severe disease. Of these patients, 30% will undergo colectomy after the acute episode, a quarter of which will experience post-operative complications. Although there has been great progress in treatment of UC over the past decade, even with the anti-TNF agent infliximab, the one-year remission rate for patients not responding to conservative management is barely 20%. Furthermore, corticosteroids have significant long-term consequences and immune suppressive drugs such as 6-mercaptopurine, azathioprine and infliximab have been associated with serious adverse events including life-threatening infections and lymphomas. With growing evidence that the pathogenesis of UC is multi-factorial and involves a complex interaction of genetic and environmental factors, newer treatment modalities are being evaluated to target the mucosal immune response and mucosal inflammatory regulatory system. Hyperbaric oxygen offers a promising new treatment option since it targets both tissue hypoxia and inflammation. Recent small scales studies evaluating the impact of hyperbaric oxygen treatment in acute ulcerative colitis flares demonstrated improved outcomes. The mechanisms underlying the improvement are not known. In this study, we will treat ulcerative colitis flares with hyperbaric oxygen and measure changes in both markers of tissue hypoxia and inflammation. We hypothesize that hyperbaric oxygen will (a) improve outcomes, and (b) show reductions in markers of both tissue hypoxia and inflammation.
The purpose of this study is to evaluate the percentage of moderate to severe IBD participants with active disease at Day 1.
Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease. UC pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota (called dysbiosis) in predisposed hosts. The purpose of this study is to determine the effect of the fecal microbiota transplantation on UC.
This clinical trial is the first-in-human study of BBT-401-1S. The purpose of this phase 1 study is to assess the safety and tolerability of single and multiple ascending oral doses of BBT-401-1S in healthy adult subjects.
This trial has two sequentially enrolling parts with different objectives. The primary objectives of this trial are - to prove the concept of clinical activity of BI655130 (SPESOLIMAB) in patients with moderate-to-severely active ulcerative colitis who have failed previous biologic treatments and to identify efficacious and safe dose regimens in Part 1 (Phase II) - to confirm efficacy and safety of BI655130 (SPESOLIMAB) in patients with moderate-to-severely active ulcerative colitis who have failed previous biologic treatments in Part 2 (Phase III) - To provide, along with induction study 1368-0018 and the run-in cohort of 1368-0020, the target population to be evaluated in study 1368-0020.
