Primary Outcome Measures:
  • Clinical efficacy change defined by a score of 180-400 on the Crohn's Disease Activity Index (CDAI) by assessment of the remission after 8-week treatment defined by a CDAI score of ≤150. [ Time Frame: baseline and Week-8 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Remission (ie, CDAI score of ≤150) after 2-week treatment [ Time Frame: baseline and Week-2 ] [ Designated as safety issue: Yes ]
  • Remission (ie, CDAI score of ≤150) after 4-week treatment [ Time Frame: baseline and Week-4 ] [ Designated as safety issue: Yes ]
  • Change in CDAI score [ Time Frame: baseline and after 2-week ] [ Designated as safety issue: Yes ]
  • Change in CDAI score [ Time Frame: baseline and Week-4 ] [ Designated as safety issue: Yes ]
  • Change in CDAI score [ Time Frame: baseline and Week-8 ] [ Designated as safety issue: Yes ]
  • Time to the first remission [ Time Frame: up to 8th Week of treatment ] [ Designated as safety issue: Yes ]
  • Clinical improvement defined by a remission (ie, CDAI score of ≤150) or a decrease in CDAI score of at least 100 from baseline [ Time Frame: baseline and week-2 ] [ Designated as safety issue: Yes ]
  • Clinical improvement defined by a remission (ie, CDAI score of ≤150) or a decrease in CDAI score of at least 100 from baseline [ Time Frame: baseline and week-4 ] [ Designated as safety issue: Yes ]
  • Clinical improvement defined by a remission (ie, CDAI score of ≤150) or a decrease in CDAI score of at least 100 from baseline [ Time Frame: baseline and Week-8 ] [ Designated as safety issue: Yes ]
  • Clinical improvement defined by a remission (ie, CDAI score of ≤150) or a decrease in CDAI score of at least 70 from baseline [ Time Frame: baseline and Week-2 ] [ Designated as safety issue: Yes ]
  • Clinical improvement defined by a remission (ie, CDAI score of ≤150) or a decrease in CDAI score of at least 70 from baseline [ Time Frame: baseline and Week-4 ] [ Designated as safety issue: Yes ]
  • Clinical improvement defined by a remission (ie, CDAI score of ≤150) or a decrease in CDAI score of at least 70 from baseline [ Time Frame: baseline and week-8 ] [ Designated as safety issue: Yes ]
  • Change in disease specific health-related quality of life (HRQL) as defined by a score of 180-400 on the CDAI by assessment of the Inflammatory Bowel Disease Questionnaire (IBDQ) total score and all sub scores [ Time Frame: baseline and Week-2 ] [ Designated as safety issue: Yes ]
  • Change in disease specific health-related quality of life (HRQL) as defined by a score of 180-400 on the CDAI by assessment of the Inflammatory Bowel Disease Questionnaire (IBDQ) total score and all sub scores [ Time Frame: baseline and Week-4 ] [ Designated as safety issue: Yes ]
  • Change in disease specific health-related quality of life (HRQL) as defined by a score of 180-400 on the CDAI by assessment of the Inflammatory Bowel Disease Questionnaire (IBDQ) total score and all sub scores [ Time Frame: baseline and Week-8 ] [ Designated as safety issue: Yes ]

Criteria

Inclusion Criteria:
