Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Characterisation of the cell populations associated with the different IBD fenotypes (CU or CD L1, L2, L3, L4). 2. Comprehensive phenotypic analysis and comparison of mucosal immune compartment in patients and controls ex vivo (year 1-3); 3.Comprehensive phenotypic analysis and comparison of mucosal stromal cell compartment in patients and controls ex vivo (year 1-3) | — |
Secondary
| Measure | Time frame |
|---|---|
| a. Comparison of immune and stromal cell compartments between pediatric and adult patients (year 1-3); b. Determination of correlates between changes in immune and stromal cell compartments and response to therapy (year 2 and 4); c. Comparison of the immune cell compartments between naïve patients and patients with active disease already on treatment to determinate the response on treatment. c. Functional analysis of selected immune and stromal cell subsets based on analysis in the endpoints above (year 3 and 4). | — |
