There is broad support for the hypothesis that Ulcerative colitis is an auto-immune disease. Rituximab is an antibody protein that removes a subgroup of white blood cells (B lymphocytes) from the circulation. These cells have the capacity to generate the auto-antibodies that typify auto-immune disease. Although Rituximab has been mainly used for treating B lymphocyte malignancies (lymphoma) it has also been used with promising results in Rheumatoid arthritis and has an excellent safety recortd. This is a small placebo-controlled trial to assess its efficacy and safety in patients with steroid-resistant active ulcerative colitis.
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
||Phase 3: Randomised Controlled Trial of Rituximab in Active Ulcerative Colitis
Primary Outcome Measures:
- Remission defined as a decrease in Mayo score to ≤ 2 points at week 4
Secondary Outcome Measures:
- Clinical response defined as a decrease in Mayo score by ≥ 3 points at weeks 4, 8 (partial Mayo score) and 12.
- Remission at weeks 8 and 12.
- Endoscopic mucosal healing at week 4 and 12
- Improvement in Inflammatory Bowel Disease specific Quality of Life Index  [Appendix 2] at weeks 4 and 12
- Histological improvement of disease activity at 4 and 12 weeks compared with baseline. Scored as follows:
- 0 = no polymorphs
- 1 = small numbers of polymorphs in the lamina propria with minimal infiltration of crypts
- 2 = prominent polymorphs in the lamina propria with infiltration of ³ 50% of crypts
- 3 = florid polymorph infiltrate with crypt abscesses
- 4 = florid acute inflammation with ulceration
- Treatment tolerability as defined by adverse events.
