  Purpose
A randomised, double-blind, placebo-controlled study to evaluate the efficacy and safety of two doses (500 mg once daily and 500 mg twice daily) of GSK1605786A in maintaining remission over 52 weeks in adult subjects with Crohn's disease. Efficacy will be assessed by the Crohn's Disease Activity Index (CDAI) score. Eligible subjects will have achieved response (CDAI decrease of at least 100 points) and/or remission (CDAI less than 150) in a prior GSK sponsored induction study. The primary endpoint will be proportion of subjects in remission at both Weeks 28 and 52. Safety will be assessed by recording of adverse events, clinical laboratory parameters including liver function tests, vital signs and electrocardiogram. Population pharmacokinetics will evaluate the two doses of GSK1605786A. Health outcomes assessments will include changes in Inflammatory Bowel Disease Questionnaire (IBDQ), SF-36v2, EQ-5D, Work Productivity and Activity Impairment - Crohn's Disease (WPAI-CD) and disability.

Primary Outcome Measures:
  • Percentage of Participants in Clinical Remission (Crohn's Disease Activity Index , CDAI Score <150 Points) at Both Weeks 28 and 52 of the 52-week Treatment Period [ Time Frame: Week 28 and 52 ]
    Clinical remission is defined as a CDAI score <150 points. In the missing=no effect imputation, participants with missing CDAI scores was considered not to be in clinical remission. Data for percentage of participants in at both Weeks 28 and 52 of the 52-week treatment period have been presented.


Secondary Outcome Measures:
  • Percentage of Participants in Clinical Remission (CDAI Score <150 Points) and Not Taking Corticosteroids at Both Weeks 28 and 52 of the 52-week Treatment Period [ Time Frame: Week 28 and 52 ]
    Clinical remission is defined as a CDAI score <150 points. A participant was considered to be not taking corticosteroids at Weeks 28 and 52 if the participant had not taken a corticosteroid for the 8 days prior to and the day of the CDAI assessment for each of Weeks 28 and 52. In the missing=no effect imputation, participants with missing CDAI scores was considered not to be in clinical remission. Data for percentage of participants in clinical remission and not taking corticosteroids at both Weeks 28 and 52 of the 52-week treatment period have been presented.

  • Percentage of Participants in Clinical Remission at Both Weeks 28 and 52 of the 52-week Treatment Period Among Those Participants Who Were in Clinical Remission at Baseline [ Time Frame: Week 28 and 52 ]
    Clinical remission is defined as a CDAI score <150 points. Among participants in remission at baseline, the percentage of participants with clinical remission at both Weeks 28 and 52 of the treatment period using the no effect imputation for missing data were to be compared between each GSK1605786A dose group and placebo using Fisher's exact test. Participants with missing CDAI scores were to be considered not to be in remission according to the missing=no effect imputation. The limited data resulting from early termination of Study CCX114157 did not allow any conclusions to be drawn about the efficacy of GSK1605786A in the maintenance of clinical remission in participants with Crohn's disease.

  • Percentage of Participants in Clinical Remission at All Visits (Continuous Clinical Remission) During the 52-week Treatment Period Among Participants in Clinical Remission at Baseline [ Time Frame: Upto Week 52 ]
    The percentage of participants with clinical remission at all visits during the 52-week treatment period were to be summarized by treatment group for the subset of participants in remission at baseline, using the no effect imputation for missing data. Participants with missing CDAI scores were to be considered not to be in remission according to the missing=no effect imputation. Comparisons between each GSK1605786A dose group and placebo were to be made using Fisher's exact test.The limited data resulting from early termination of Study CCX114157 did not allow any conclusions to be drawn about the efficacy of GSK1605786A in the maintenance of clinical remission in participants with Crohn's disease.

  • Percentage of Participants in Clinical Remission at Week 52 [ Time Frame: Week 52 ]
    The limited data resulting from early termination of Study CCX114157 did not allow any conclusions to be drawn about the efficacy of GSK1605786A in the maintenance of clinical remission in participants with Crohn's disease.

  • Percentage of Participants With a Clinical Response (CDAI Decrease >=100 Points) at Both Weeks 28 and 52 of the 52-week Treatment Period [ Time Frame: Week 28 and 52 ]
    Clinical response is defined as a reduction from the induction study baseline CDAI score of >=100 points. The percentage of participants with a clinical response at both Weeks 28 and 52 of the 52-week maintenance treatment period in the ITT population using the no effect imputation for missing data were to be compared between each GSK1605786A dose group and placebo using Fisher's exact test. Participants with missing CDAI scores were to be considered non-responders according to the missing=no effect imputation. The limited data resulting from early termination of Study CCX114157 did not allow any conclusions to be drawn about the efficacy of GSK1605786A in the maintenance of clinical remission in participants with Crohn's disease.

  • Time to Induction of Clinical Remission in Participants Who Had Achieved Clinical Response During Induction Therapy But Were Not in Clinical Remission at Baseline [ Time Frame: Upto Week 52 ]
    The duration of time participants maintained clinical remission during the 52-week treatment period was to be defined as the time between Week 0 and the first visit where remission was not observed in those participants in remission at baseline. These time periods were to be summarized by treatment group using quartiles and their corresponding confidence intervals. Comparisons between each GSK1605786A dose group and placebo were to be made using log-rank tests. The limited data resulting from early termination of Study CCX114157 did not allow any conclusions to be drawn about the efficacy of GSK1605786A in the maintenance of clinical remission in participants with Crohn's disease.

    The CDAI score is used to quantify the symptoms of participants with Crohn's Disease. A score of 150 or below indicates remission and a score above 450 indicates extremely severe disease. A decrease in CDAI over time indicates improvement in disease activity. CDAI scores and changes in CDAI scores during the 52-week treatment period were to be summarized by treatment group at Weeks 4, 8, 12, 20, 28, 36, 44, and 52. The limited data resulting from early termination of Study CCX114157 did not allow any conclusions to be drawn about the efficacy of GSK1605786A in the maintenance of clinical remission in participants with Crohn's disease. Baseline was defined as value at Week 0. Change from Baseline was calculated by subtracting the Baseline value from the post-randomization value at the time of assessment.

  • Change From Baseline in Inflammatory Bowel Disease Questionnaire (IBDQ) Total Score at Week 52 [ Time Frame: Baseline (Week 0) and Week 52 ]
    The IBDQ consists of a self-administered 32-item questionnaire that evaluates quality of life across 4 dimensional scores: Bowel, Systemic, Social and Emotional. The IBDQ questionnaire was to be completed by each participant at baseline and at Weeks 28, and 52. The response to each question can range from 1 to 7, with 1 indicating severe problem and 7 indicating normal health. The total IBDQ is computed as the sum of the responses to the individual IBDQ questions. The total score can range between 32 to 224 with higher scores indicating a better quality of life. The limited data resulting from early termination of Study CCX114157 did not allow any conclusions to be drawn about the efficacy of GSK1605786A in the maintenance of clinical remission in participants with Crohn's disease. Baseline was defined as value at Week 0. Change from Baseline was calculated by subtracting the Baseline value from the post-randomization value at the time of assessment.

Detailed Description:
This is a multi-centre, randomised, placebo-controlled, double-blind parallel group study in adult subjects with Crohn's disease who previously achieved clinical response (CDAI decrease of at least 100 points) and/or remission (CDAI less than 150) in a prior Phase III induction study (Study CCX114151 or another GSK sponsored induction study). Subjects will be randomised to 52 weeks of oral treatment with GSK1605786A 500 mg once daily or 500 mg twice daily or placebo. Subjects who are receiving concomitant corticosteroids at entry will undergo dose tapering following a defined schedule. Subjects who complete the treatment period may be eligible to enter an open-label extension study. Subjects who experience disease worsening and require additional (rescue) treatment will be withdrawn and may be eligible to enter the open-label study. Subjects who do not enter the open-label study must complete a follow-up assessment 4 weeks after completion of treatment. Approximately 756 subjects will be enrolled.
