This study is an open-label study aiming at evaluating the long-term safety and the efficacy profile of ABX464 given once a day (o.d) at 50 mg in subjects who have been previously enrolled in the ABX464-101 clinical study (induction study) and who are willing to continue their treatment.
Inflammatory Bowel Diseases (IBD) is a heterogeneous group of diseases regarding clinical presentation, disease course and treatment response. Pathogenesis is complex and multifactorial, based on interactions between genetic and environmental factors, gut microbiota and the immune system, leading to intestinal inflammation. As the immune reaction itself causes the intestinal damage, differences in components of this immune mediated inflammatory reaction between IBD patients might explain the heterogeneity in response to different therapy strategies. Identifying immune components that are associated to disease activity and prognosis would enable a more personalized treatment.
Spondyloarthritis and inflammatory bowel diseases are common diseases, frequently met together in overlap syndromes. Their physiopathology remains puzzling. A strong role of gut microbiota has been recently put forward to explain the development of inflammatory bowel diseases, and is suspected to play an important role in rheumatoid diseases. Anti-Tumor Necrosis Factor (anti-TNF) alpha are effective and safe drugs in the treatment of both digestive and rheumatoid inflammatory diseases. The way they work is unclear, and the clinical response to this treatment is variable. A better understanding of the pathophysiology of inflammatory bowel diseases and of the action of anti-TNF alpha is essential to an optimized care. Our hypothesis is that the efficacy of anti-TNF alpha in spondyloarthritis and in inflammatory bowel diseases is at least partly due to its restoring action of homeostasis at the interface between gastrointestinal mucosa and intestinal microbiota, either by primary action on the digestive epithelium, allowing it to regain its control and tolerance functions toward mucosal microbiota, either by direct action on the intestinal microbiota, via an inter-reigns regulation. The main objective of our study is to assess quantitative and qualitative changes in fecal microbiota before (D0) and 3 months after initiation of anti-TNF alpha.
This is a phase 2, multicenter, randomized, double-blind, placebo-controlled, dose-finding study to evaluate the efficacy and safety of IMU-838 for induction and maintenance therapy in moderate-to-severe ulcerative colitis (CALDOSE-1).
IBD adds additional stressors as a chronic disease that has unpredictable and sometimes embarrassing symptoms to the normal challenges that teenagers face. Stress and how stressful events are perceived, may contribute to worsening of disease. Complementary and alternative medicine (CAM), are used often by pediatric IBD patients and maybe beneficial in decreasing stress and improving quality of life. Yoga could be a well suited paring with standard medical therapy to decrease and provide a better sense of control and improve quality of life.
The objective of this study is to evaluate and compare the bioavailability of mesalamine
Inflammatory Bowel Diseases (IBD) are chronic debilitating disorders of the gastrointestinal tract that comprise two subtypes; Crohn's Disease (CD) and Ulcerative Colitis (UC). Canada has among the highest incidence rates of CD and UC in the world, as high as 20.2 and 19.5 per 100,000 respectively. Although, IBD can occur at any age, it is frequently diagnosed in the second and third decades of life, at a time when vulnerable individuals are entering the prime years of their lives. This age of onset, coupled with the recurrent and frequently relapsing nature of these disorders, can significantly impair the psychological well-being of patients. Therefore, it's not surprising that patients with IBD report a higher burden of depression and anxiety in comparison to the general population. The prevalence of depression and anxiety in patients with IBD have previously been linked to the following: (1) Increased risk of surgery; (2) Increased number of relapses; (3) Clinical recurrence; (4) Treatment failure and earlier retreatment; (5) Lower self-reported quality of life, satisfaction, and medication adherence; (6) and Increased health care utilization. Although, depression and anxiety are highly treatable conditions, they are often under-recognized and under- treated in patients with IBD. The most common treatments for these disorders are pharmacological agents and psychological treatments. Psychological treatments like Cognitive Behavioral Therapy (CBT) have extensive support for treatment of depression and anxiety. The major advantage of psychological treatments over pharmacological agents is their ability to sustain improved depression and anxiety symptoms in patients post-treatment. As part of this study, we aim to evaluate the following: Specific Aim #1: Determine whether a psychological intervention, involving web-based CBT, is effective in ameliorating depression and anxiety symptoms in a cohort of adult IBD patients. Specific Aim #2: Determine the durability effect of the intervention on sustaining improved psychiatric symptoms. Specific Aim #3: Determine the impact of a psychological on IBD-specific and psychiatric-specific health care utilization.
Graves disease in ulcerative colitis: The connection between Graves disease and Inflammatory bowel disease is well known in the literature, but thyroid disorders have not been considered extra-intestinal manifestations of ulcerative colitis. In most cases, the diagnosis of thyroid disease has preceded that of Inflammatory bowel disease. Early studies have suggested a relationship between thyroid abnormalities and ulcerative colitis . But it is still uncertain whether the coexistence of Grave's and ulcerative colitis diseases is due to a specific reason or a coincidence.
Research of fecal microflora and dysbiosis status in ulcerative colitis (UC) has shown its influential role on the disease pathogenesis. Vedolizumab, a humanized monoclonal antibody blocking the migration of leukocytes into inflamed intestinal tissue, has been shown to achieve remission in about half of active UC patients. Dietary intervention in UC patients has not been adequately studied. There is a significant clinical gap to achieve a higher efficacy and better clinical outcomes on the treatment of active UC patients. This study proposes to assess the integrated effect of normalization of intestinal dysbiosis through a structured semi-vegetarian dietary intervention in active UC patients who will also be under the standard of care medical therapy (vedolizumab). Significance of investigation for innovation: The pathogenesis of UC has been found to be multi-factorial, including host genetics and dysregulated inflammatory response, and recent research has shown the influential role of gut environmental factors - dysbiosis which has been found the key feature of UC. Vedolizumab has been shown effective (e.g. 47% clinical response rate vs. 25% in placebo group) and is part of the current standard of care treatment in UC. With the observation of drastic increase of IBD patients in Asia, in which has historically low incidence of IBD, it is generally accepted that the westernized diet and urbanization of life style play an important role in IBD pathogenesis. Enteral nutritional therapy has been demonstrated effective in pediatric Crohn's disease (CD) patients; however, the application to adult IBD patients has not been widely accepted partly because of the compliance issue. In addition, unlike CD, neither enteral nutrition nor non-enteral nutrition in patients with active UC has been adequately studied. Therefore, this study proposes a novel approach to assess the integrated effect of a structured dietary intervention in active UC patients who will also be under the current standard of care medical therapy (vedolizumab). After this study achieves the proposed primary or secondary outcome, it will further support the hypothesized synergistic interactive therapeutic effect between the normalization of dysbiosis in the intestine (through dietary intervention) and anti-inflammatory biologics (vedolizumab).
A series of N-of-1 trials will be used to determine the effectiveness of a specific carbohydrate diet (SCD) versus a modified SCD in patients in reducing symptoms and inflammatory burden at both the individual and population level. This is a three-year study. The study staff will recruit 120 patients (goal sample size of 100, accounting for attrition) across up to 12 sites in patients aged 7-17 with mild to moderate disease activity.
