The objectives of the study are to observe and document the efficacy and safety of 5 or more Adacolumn treatments, administered once weekly over 5 or more weeks, in a specific subset of ulcerative colitis patients. The patient subset of interest is those with moderate/severe, steroid-dependent, active ulcerative colitis with insufficient response or intolerance to immunosuppressants and/or biological agents.

Inclusion criteria

Patients enrolled into the study will be between 18 and 75 years old and have moderate to severe, steroid-dependent, active ulcerative colitis documented by clinical symptoms, endoscopic findings and histology. Patients will have an ulcerative colitis clinical activity (CAI) of ≥6 and an endoscopic activity index (EAI) of ≥4. Patients will have an insufficient response or intolerance to immunosuppressants and/or biological treatment agents. Patients are required to have adequate peripheral venous access to allow completion of apheresis treatment.

A patient will be excluded from the study if he/she meets any of the following criteria:

Is febrile (body temperature >38ºC).
Has evidence of toxic megacolon.
Has known obstructive disease of the gastrointestinal system.
Is anticipated to need surgery within the next 24 weeks.
Has a history of hypersensitivity reaction associated with an apheresis procedure or an intolerance to apheresis procedures.
