  • AZA, 6-MP, MTX: 8 weeks immediately prior to randomization
  • 5-ASA: 4 weeks immediately prior to randomization
  • Corticosteroids: 4 weeks immediately prior to randomization; if corticosteroids are being tapered, dose has to be stable for at least 2 weeks prior to randomization
  • Use of highly effective contraception method as defined by the protocol
