An Active Treatment Study to Induce Clinical Response and/or Remission With GSK1605786A in Subjects With Crohn's Disease

Study Summary

This is a multi-centre, randomised, double-blind, active treatment, parallel group induction study in subjects with moderately-to-severely active Crohn's disease. Subjects will receive one of two doses (500 milligrams once daily, 500 milligrams twice daily) of GSK1605786A for 12 weeks. The primary objective of the study is to induce clinical response (Crohn's Disease Activity Index \[CDAI\] decrease from baseline of at least 100 points) and/or remission (CDAI score less than 150) with GSK1605786A at Week 12 in subjects with active Crohn's disease to qualify subjects for enrolment into a 52 week maintenance study (CCX114157). Secondary objectives will include assessment of the safety and evaluation of the efficacy in induction of clinical response or remission. Safety will be assessed by recording of adverse events and assessment of changes in clinical laboratory parameters, vital signs and electrocardiogram. Population pharmacokinetics will evaluate the two doses of GSK1605786A. Health outcomes assessments will include changes in Inflammatory Bowel Disease Questionnaire, SF-36, EQ-5D, and Work Productivity and Activity Impairment-Crohn's Disease.

Primary Outcome

Clinical response, defined as decrease in Crohn's disease activity index (CDAI) score, from Baseline value of \>=100 points. Baseline defined as Week 0. CDAI is scoring system measuring disease severity with scores of \>=220 to \<=450 describing moderately-to-severely active population(higher score indicated severe disease). Contains 8 questions related to disease symptoms; soft tools in 7 days (weightage (Wt)as 2; abdominal pain over 7 days Wt= 5; general well being Wt= 7;Crohn's disease sympto
