Primary Outcome Measures:
  • Percent change from baseline (pre treatment) in absolute lymphocyte count in CSF in subjects with CD or UC after receiving 3 monthly doses of PF-00547659 [ Time Frame: Week 9-11 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

  • Proportion of subjects developing anti-drug antibodies (ADA) to PF-00547659 [ Time Frame: Week 36 ] [ Designated as safety issue: Yes ]
  • Frequency of injection site reactions and other hypersensitivity reactions [ Time Frame: Week 36 ] [ Designated as safety issue: Yes ]
