Open to people ages 18-80

  • Moderately to severely active UC as determined by an MCS of 6-12 with an endoscopic subscore greater than or equal to (>=) 2 as determined by the central reading procedure (endoscopy to be performed 4-16 days prior to Day 1), a rectal bleeding subscore >=1, and a stool frequency subscore >= 1 during the screening period (prior to Day 1)
  • Evidence of UC extending a minimum of 20 centimeters (cm) from the anal verge as determined by baseline endoscopy (flexible sigmoidoscopy or colonoscopy) performed during screening, 4-16 days prior to Day 1
  • Naive to treatment with any anti-TNF therapy
  • Participants must have had an inadequate response, loss of response, or intolerance to prior corticosteroid and/or immunosuppressant treatment
  • Background regimen for UC may include oral 5-aminosalicylate (5-ASA), oral corticosteroids, budesonide multi-matrix system (MMX), probiotics, azathioprine (AZA), 6-mercaptopurine (6-MP), or methotrexate (MTX) if doses have been stable during the screening period
  • Use of highly effective contraception
  • Must have received a colonoscopy within the past year or be willing to undergo a colonoscopy in lieu of a flexible sigmoidoscopy at screening
