• Research summary

  Ulcerative colitis (UC) is an inflammatory bowel disease characterised by chronic, relapsing, inflammatory disease of the colon. Although the precise cause is unknown, UC is thought to arise as a result of the body being unable to appropriately downregulate its immune response to certain pathogens (bad bacteria) that live naturally in our gut. This defective immune response results in periods of enhanced inflammation and tissue damage with symptoms including diarrhea, rectal bleeding and abdominal pain. Patients will typically experience intermittent flare-ups of the disease, followed by periods of disease remission. Current therapies include anti-inflammatory drugs, steroids and immunosuppressants; however, a significant proportion of UC patients still require colectomy (partial or total removal of the large bowel through surgery) or restorative proctocolectomy (surgical removal of the rectum and all or part of the colon with restoration of continuity). These procedures are often considered as a cure for UC, however the resultant effects to the patients quality life mean alternative pharmacological alternatives are desirable. The primary treatment goal of new therapies is to induce remission and then maintain this state. CP-690,550 is a chemical inhibitor that can act to suppress the immune system by blocking the production of molecules that stimulate the immune response. This clinical trial aims to assess the effectiveness of CP-690,550 in inducing remission in patients suffering moderate to severe active ulcerative colitis. The study involves a screening period, followed by a 9-week blinded treatment period, and a 4 week safety follow-up (for patients not involved in the maintainence study (A3921096) or the open-label study (A3921139)). Approximately 545 patient will be enrolled, throughout the study these patients will undergo: - Physical examinations, vital signs, and ECG - Blood samples for laboratory analysis - Endoscopic procedures - Ulcerative colitis assessments - Health outcome assessment questionnaires.
