RCT to evaluate possible pharmacokinetic differences between the two current regimes of intensified adalimumab administration.


IBD patients in need of intensified adalimumab treatment will be randomized to receive 40mg sc weekly or 80mg sc every two weeks, and after 6 weeks of treatment each of the groups will be allocated to the other dosing regime. Adalimumab blood levels and other features such as specific drug antibodies and disease activity parameters will be compared between both groups.
