E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study was to estimate the dose response in subjects with active Crohn’s Disease (CD), and to evaluate the efficacy of certolizumab pegol in these subjects.
|
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives were to evaluate the safety and tolerability of certolizumab pegol in subjects with active CD and to obtain data on the plasma certolizumab pegol concentrations and anti-certolizumab pegol antibody levels up to Week 16 following dosing at Weeks 0, 2, and 4 (induction period).
