Biomarkers to Predict and Monitor Response to Infliximab
- Conditions
- Crohn Disease
- Registration Number
- NCT04655729
- Lead Sponsor
- Massachusetts General Hospital
- Brief Summary
The aim of the study is to generate novel minimally-invasive serum protein signatures and biomarkers in children and adolescents with Crohn's Disease (CD) that correlate with and can predict and monitor patients who will have a prolonged response to Infliximab so that personalized medicine can be applied to patients with CD.
- Detailed Description
Prospective, observational study will enroll 120 unique pediatric Crohn's disease patients between the ages of 3-20 years among multiple sites. Patients will be naïve to TNF inhibitor. If patient is going to start infliximab or infliximab biosimilar, patient may be enrolled in study. Study length will be from commencement of infliximab until the infusion visit given at least 1 year after initiation. During the study, if the patient fails infliximab or biosimilar, they will be complete study once failure is indicated and discontinued on infliximab or biosimilar. Patients may be on concurrent IBD therapy such as antibiotics, mesalamines, immunomodulators and may continue in study if non-standard induction schedule or changes made during induction or maintenance to dose or frequency. Excluded patients will be those receiving infliximab or biosimilar infusions at home due to need for blood collection at time of infusion, on systemic corticosteroids (topical preparations such as budesonide are allowed), and those who have already undergone significant bowel surgery relating to their Crohn's.
Study visits will take place in conjunction with previously scheduled routine clinic visits or infusion visits. At initial study visit, demographics, medical and surgical history, PARIS classification, PCDAI, weight and height, fecal calprotectin, labs, EGD and colonoscopy report and pathology report, cross-sectional imaging reports and concurrent medications will be obtained and entered. Parameters measured at each study visit will include any obtained labs, weight and height, PARIS classification, PCDAI, infliximab dose (mg/kg) and dose interval. There will be four study visits throughout the course of 1 year after initiating infliximab. At these four visits, blood will be obtained in PAXgene tubes for RNA analysis and serum for banking for SOMAscan analysis.
