• Use of any biologics for the treatment of ulcerative colitis in the previous 8 weeks before screening
• Requirement for concomitant treatment that could bias primary evaluation
• Pregnant or breast-feeding women
• Women of childbearing potential not protected by highly effective contraceptive method of birth control

• Patient with latent or active tuberculosis (TB) defined as:

  • Any signs or symptoms suggestive of active TB upon medical history or clinical examination
  • Patients with a positive QuantiFERON TB Gold Test
  • Chest radiograph within 3 months prior to the inclusion visit consistent with prior tuberculosis infection including, but not limited to, apical scarring, apical fibrosis, or multiple calcified granulomasa. This does not include non-caseating granulomasa
  • Patients with close contact with a person with active tuberculosis
• Patient with a history of listeriosis or tuberculosis (unless it is documented that they were adequately treated)
• Administration of any live (attenuated) vaccine within 3 months prior to the screening Visit (eg, varicella-zoster vaccine, oral polio, rabies)

• Prior opportunistic infections within 6 months prior to screening or while receiving anti-TNF treatment
• History of a hypersensitivity reaction, other than localized injection site reaction, to any biological molecule
• History or any current signs of demyelinating disease or any neurological disease that can by the opinion of Investigator interfere with study safety assessments including assessment for progressive multifocal leukoencephalopathy
