Conditions
Keywords
Acute Severe Ulcerative Colitis, Steroid Refractory Ulcerative Colitis
Brief summary
The purpose of this study is to identify whether an Accelerated or Intensified Infliximab induction regimen is superior to Standard induction in Acute Severe Ulcerative Colitis in an open label multi-centre randomised controlled trial.
Interventions
INFLIXIMAB (REMICADE) in the form of a freeze-dried compound is conditioned in 100mg vials. Treatment will first be reconstituted in 250ml isotonic saline solution and infused
