Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Male or female, ≥18 years of age, who has a diagnosis of active UC for at least 6 months prior to screening
  • A rectal/colonic biopsy obtained previously and consistent with a diagnosis of UC
  • Endoscopy (flexible sigmoidoscopy unless surveillance colonoscopy is clinically indicated) confirming diagnosis of UC within 2 weeks prior to randomization
  • Endoscopy (flexible sigmoidoscopy unless surveillance colonoscopy is clinically indicated) confirming diagnosis of UC within 2 weeks prior to randomization
  • Active UC despite previous treatment with at least one 5-ASA compound at a dose of ≥2000 mg/day for at least 4 weeks or documented intolerance to such therapy

Exclusion Criteria:

  • Diagnosis of indeterminate colitis, Crohn's disease, or clinical findings suggestive of Crohn's disease (fistula or granulomas on biopsy) or microscopic colitis (collagenous colitis or lymphocytic colitis)
  • Subject whose symptoms are likely caused by factors other than inflammatory UC, including infection or irritable bowel syndrome (IBS)
  • History of dysplasia on colonic biopsy
  • Subject with ≥ 8 year history of pancolitis or ≥ 15 year history of left sided colitis unless a colonoscopy with surveillance biopsies to screen for colon cancer has been performed within the past year
  • Subject ≥ 50 years of age who has not had a colonoscopy to screen for colorectal polyps and colon cancer within the past 5 years
  • Subject who has had any prior surgical resection of any part of the colon excluding the appendix
  • Previous treatment with any biologic product including investigational biologic products within 1 year prior to baseline visit
  • The subject is taking Systemic corticosteroids, Azathioprine/6-mercaptopurine/methotrexate, immunosuppressants, Oral 5-ASA compounds unless they have been on a stable dose of sufficient duration prior to Baseline. If recently discontinued the subject must have had a wash-out periods of sufficient duration prior to Baseline
  • Rectally administered corticosteroids or 5-ASA, antibiotics for the treatment of UC and probiotics within 14 days of the Baseline Visit and throughout the study
  • The subject has with a stool culture positive for pathogenic ova or parasites, enteric pathogens or Clostridium difficile toxin at the Screening Visit
