Sponsor's own description

The aim of the study is to investigate the effect of re-induction with ustekinumab ≈6mg/kg IV followed by two different maintenance dosing regimens 90 mg subcutaneous every 8 weeks (Q8W) vs 90 mg subcutaneous every 4 weeks(Q4W) on clinical, biological and pharmacological outcomes in patients with Crohn's disease who show a secondary loss of response over time
