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.
Ulcerative Colitis, Active Moderate
Device: (GMA) Adsorptive Apheresis
||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||Multicentre Investigation of the Efficacy and Safety of Adacolumn® GMA in Patients With Steroid-Dependent Active Ulcerative Colitis and Insufficient Response or Intolerance to Immunosuppressants and/or Biological Therapies
Primary Outcome Measures:
- The primary efficacy endpoint is the ulcerative colitis remission rate at Week 12, defined as a CAI (Rachmilewitz) score of ≤4. [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- Ulcerative colitis response rate at Week 12, with response defined as a reduction in CAI of ≥3. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
- Response and remission rates at Weeks 24 and 48 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
- Change from Baseline in CAI at Weeks 12, 24 and 48 [ Time Frame: 12 weeks, 24 weeks and 48 weeks ] [ Designated as safety issue: No ]
- Change from Baseline in EAI at Week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
- Time to remission and response [ Time Frame: Baseline ] [ Designated as safety issue: No ]
- The proportion of patients reaching steroid-free remission/steroid-free response at any visit and by visit at Weeks 12, 24 and 48. [ Time Frame: 12 weeks, 24 weeks and 48 weeks ] [ Designated as safety issue: No ]
- Time to steroid-free remission and response. [ Time Frame: Baseline ] [ Designated as safety issue: No ]
- Colectomy rate at Week 96 [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
- Change from Baseline in concomitant medication (steroid) dose at Weeks 12, 24 and 48. [ Time Frame: 12 weeks, 24 weeks and 48 weeks ] [ Designated as safety issue: No ]
- Quality of life changes based on the Short Health Scale for ulcerative colitis at Weeks 5, 12, 24 and 48. [ Time Frame: 5 weeks, 12 weeks, 24 weeks and 48 weeks ] [ Designated as safety issue: No ]

|Ages Eligible for Study:
||18 Years to 75 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- 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.

- 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.
- Has proctocolectomy, total colectomy, ileostomy, stoma or ileal pouch-anal anastomosis.
- Has a history of allergic reaction to heparin or of heparin-induced thrombocytopenia.

- Has symptomatic hypotension.
- Has a history of physical findings consistent with a cerebrovascular accident.
- Has a history of myocardial infarction or unstable angina within the previous 6 months.
- Has undergone coronary artery bypass graft surgery or angioplasty within the previous 6 months.
- Has congestive heart failure (New York Heart Association Class III or IV).
- Has a prosthetic heart valve, pacemaker or other permanent implant.
- Has severe cardiovascular or peripheral vascular disease.
- Has liver disease defined as levels of aspartate aminotransferase (AST/SGOT), alanine aminotransferase (ALT/SGPT) or alkaline phosphatase of greater than 2.5 × the upper limit of the normal range for the laboratory performing the test.
- Has a history of cirrhosis.
- Has a known bleeding disorder (prothrombin time [PT] or partial thromboplastin time [PTT] greater than 1.5 × the upper limit of the normal range for the laboratory performing the test) or requires concomitant anticoagulant therapy for purposes other than apheresis treatment.
- Has a prior history suggestive of a hypercoagulable disorder, including 1 or more episodes of pulmonary embolism or deep vein thrombosis.
- Has a known infection with hepatitis B or C or human immunodeficiency virus.
- Has abnormal haematology parameters defined as severe anaemia with haemoglobin <8.5 g/dL, white blood cell count <3500/µL or granulocyte count <2000/µL.
- Has a fibrinogen level >700 mg/dL.
- Has renal insufficiency, defined as a serum creatinine level greater than 150% of the upper limit of the normal range for the laboratory performing the test.
- Has had major surgery within the previous 6 weeks.
