Inclusion criteria

  • Confirmed diagnosis of UC at least 12 weeks before screening based on clinical, endoscopic, and histopathological evidence.
  • Have a 3-component Mayo score of 4 to 9, which includes a modified Mayo Endoscopy Score (mMES) of ≥ 2 as determined by a central reader, a rectal bleeding score of ≥ 1, and a stool frequency score of ≥ 1.
  • Must have failed or be intolerant to (discontinued the medication due to an adverse event as determined by the investigator) at least 1 of the following treatments for UC: Oral corticosteroids, azathioprine or 6-mercaptopurine, biologic therapy (eg, infliximab, vedolizumab or adalimumab).
  • Participants currently receiving the following treatment(s) for UC are eligible, provided they have been receiving acceptable and stable dose(s): oral 5-ASA or oral corticosteroids.
  • No evidence of active or latent or inadequately treated tuberculosis infection.
  • Willingness to avoid pregnancy or fathering children.

Exclusion criteria

  • Clinical signs of fulminant colitis or toxic megacolon.
  • Presence of indeterminate colitis, microscopic colitis, ischemic colitis, infectious colitis, or clinical or radiographic findings suggestive of Crohn's disease.
  • Disease limited to the distal 15 cm of the colon.
  • Receiving (or expected to receive) the following therapies within protocol-designated timeframes before the baseline visit or during the study: Natalizumab; anti-TNF therapy; Vedolizumab or any investigational anti-adhesion molecule therapy; Ustekinumab or any on or off label biologic therapy; interferon therapy; cyclosporine, mycophenolate, or tacrolimus; daily dose of oral corticosteroids ≥ 25 mg prednisone or equivalent; intravenous corticosteroids; rectally administered formulation of corticosteroids or 5-aminosalicylic acid; and AZA, 6-MP, or methotrexate.
  • Enema treatments within 2 weeks of the baseline visit, with the exception of enema bowel preparations for clinical assessments.
  • Positive stool examinations for enteric pathogens, pathogenic ova or parasites, or Clostridium difficile toxin at the screening visit.
  • Other immunocompromised states and history of opportunistic infections.

History of stomach or intestinal surgery, including bariatric surgery (Note: appendectomy and/or cholecystectomy, is allowed).

o surgery for UC or likely to require surgery for UC during the study.

  • If at risk for colorectal cancer, must have had a colonoscopy within protocol-defined timeframes.
  • History of recurrent, disseminated, or multiple dermatomal herpes zoster.
  • History of alcohol or drug abuse.
  • History of active malignancy within 5 years of screening, excluding superficial basal and squamous cell carcinoma of the skin and adequately treated carcinoma in situ of the cervix.
  • Current or recent history (within 30 days before randomization) of a clinically meaningful viral, bacterial, fungal, parasitic, or mycobacterial infection.
  • Previously received either lymphocyte apheresis or selective monocyte granulocyte apheresis (eg, Cellsorba) within 1 year of baseline.
  • History of unstable ischemic heart disease or uncontrolled hypertension.
  • Positive serology test results for HIV, for hepatitis B surface antigen or core antibody, or for HCV antibody with detectable RNA at screening.
  • Participants taking potent systemic CYP3A4 inhibitors or inducers or fluconazole within 2 weeks or 5 half-lives (whichever is longer) of baseline.
  • Participants taking P-gp substrates with narrow therapeutic index, including digoxin within 2 weeks or 5 half-lives (whichever is longer) of baseline.
