This study will assess the safety and tolerability of AIN457 in patients with moderate to severe Crohn's disease who already participated and completed the core trial CAIN457A2202.
The purpose of this study is to provide data correlating levels of microparticles that circulate in the blood and disease activity in children with inflammatory bowel disease (IBD). The hypothesis is that circulating microparticles will be higher in children with active IBD, show inflammatory activity, and will be low in patients in remission as well as in healthy controls.
The primary purpose of this study is to pilot test an instrument that the investigators will develop to assess decision influences on inflammatory bowel disease patients' medication adherence decision-making. This pilot study will use an exploratory, descriptive cross-sectional survey approach to pilot test the instrument and answer the research questions. The main hypothesis is that patients at risk for intentionally modifying their prescribed medication regimen will differ on influences on decision-making, health status, and utilization of the IBD clinic services compared to those who are intentionally adherent and who continue adherence over time.
The investigators will prospectively recruit 26 children with moderate - severe active Crohn disease (PCDAI >30). Results will be compared to 26 patients in sustained remission (PCDAI <10 and physician global assessment of remission over the previous 6 months) who are matched for age and gender. Subjects will be studied at baseline and six months. The primary study end-points will be leucine rate of appearance (a measure of protein breakdown) and IGF-1 levels. This study will test the hypothesis that children with greater disease severity will have worse longitudinal growth and protein catabolism. The investigators will also explore the secondary hypothesis that children with Crohn disease have abnormal IGF-1 generation which is linked to underlying inflammation and disease severity.
The objective of this NIH-specific substudy is immunologic monitoring of cytokine and immune cell responses in subjects undergoing treatment with AIN457 (human monoclonal anti-human interleukin-17A) for moderate to severe Crohn's disease. Recent data suggests that interleukin-17 (IL-17) is an important mediator of inflammation in certain animal models of Crohn's disease, and treatment aimed at blocking the IL-23-IL-17 axis can ameliorate the inflammatory changes. In addition, elevated expression of IL-l7 has been found in the gut tissue of patients with active Crohn's disease. This substudy will measure changes in cytokine production, relevant RNA expression, and immune cell populations (in the periphery and lamina propria) for correlation with clinical outcomes in order to explore the mechanisms of therapeutic response.
The purpose of this study is to evaluate the safety, efficacy, pharmacokinetics, and immunogenicity of certolizumab pegol treatment in pediatric subjects, aged 6 to 17, with moderately to severely active Crohn's disease. The target enrollment is 160 subjects.
The purpose of this trial is to demonstrate that Pentasa administered as a 2 g morning dose and a 4 g evening dose is efficacious in active mild to moderate CD.
This is a double-blind, double-dummy, prednisolone-controlled, multi-center, randomized, parallel-group clinical study to evaluate the therapeutic efficacy of repeated infliximab infusions in order to maintain Crohn's disease remission at the end of the study.
Objectives: The primary objective of the study was to determine the ability of ITF2357, administered orally at the dose of 50 mg b.i.d. for 8 consecutive weeks, to induce complete healing of mucosal ulcerations of ileum and/or colon, assessed by endoscopy, in patients with endoscopic and clinical evidence of active moderate-to-severe Crohn's disease not controlled by conventional therapies. The secondary objectives of the study were: - to evaluate the effect of ITF2357 on endoscopic disease activity assessed using both the Crohn's Disease Endoscopic Index of Severity (CDEIS) and the Simple Endoscopic Score of Crohn's Disease (SES-CD); - to evaluate the effect of ITF2357 on clinical disease activity, assessed using the Crohn's Disease Activity Index (CDAI); - to assess the safety and tolerability of ITF2357; to assess the pharmacokinetic profile of ITF2357.
