Primary Outcome Measures:
  • The proportion of subjects in clinical remission at week 8 as defined by a Crohn's disease activity index (CDAI) score of less than 150 points. [ Time Frame: week 8 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The proportions of subjects in clinical remission (CDAI<150) at Week 2 and 4. [ Time Frame: week 2 and 4 ] [ Designated as safety issue: No ]
  • The proportion of subjects achieving clinical response-70 at Week 2, 4, and 8 as defined by a decrease in CDAI score of at least 70 points from baseline. [ Time Frame: week 2, 4 and 8 ] [ Designated as safety issue: No ]
  • The proportion of subjects achieving clinical response-100 at Week 2, 4, and 8 as defined by a decrease in CDAI score of at least 100 points from baseline. [ Time Frame: week 2, 4 and 8 ] [ Designated as safety issue: No ]
  • The proportion of subjects achieving either clinical response-100 or clinical remission (CDAI<150) at Week 2, 4, and 8. [ Time Frame: week 2, 4 and 8 ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria:

  • Male or female subjects between the ages of 18 and 75 years at screening (upper age limit will be 64 years in India and 65 years in the Netherlands).
  • Subjects with clinical diagnosis of Crohn's disease for at least 6 months prior to screening.

Exclusion Criteria:

  • Diagnosis of indeterminate colitis, ulcerative colitis (UC), or clinical findings suggestive of UC.
  • Subjects diagnosed with Crohn's disease but without previous exposure to treatment (i.e., treatment-naïve).
  • Subjects receiving the following treatment for Crohn's disease:
  • Azathioprine, 6-mercaptopurine or methotrexate within 2 weeks prior to baseline.
  • Anti-TNFα therapy within 8 weeks prior to baseline.
