- For participants outside of the United States: have had an inadequate response or been intolerant to at least one prior therapy as listed below or have a medical contraindication to such therapies:
- Oral or intravenous (IV) corticosteroids;
- Azathioprine or 6-mercaptopurine;
- TNF inhibitors or anti integrin therapy.
- For participants in the United States: have had an inadequate response or intolerance to TNF inhibitors.
- Stable doses of the following therapies for UC:
- Oral 5 Aminosalicyclic acids (ASA) or sulfasalazine
- Oral corticosteroids equivalent to prednisone at most 1 mg/kg up to a maximum of 20 mg/day or budesonide up to 9 mg/day.
- evidence of prior varicella zoster virus exposure based on serological testing.
- female participant is eligible if she is not pregnant or breastfeeding, If she is a woman of child bearing potential, she needs to be using a contraceptive method that is highly effective (with a failure rate of <1% per year).
- Diagnosis of indeterminate colitis, isolated proctitis, microscopic colitis,
infectious colitis, Crohn's disease, or clinical findings suggestive of Crohn's
- History of symptomatic obstructive intestinal strictures or active ostomy, or history
of colectomy, extensive small bowel resection ( greater than100 centimetres) or short
bowel syndrome, or hospitalization for UC related reason(s) within 4 weeks of baseline
- Any factors or clinical characteristics potentially related to the risk of venous
thromboembolism that may increase the risk associated with study participation or
study intervention administration or may interfere with the interpretation of study
results and, in the judgment of the investigator, would make the participant
inappropriate for entry into this study.
- Participants who have previously received tofacitinib or another Janus Kinase
- Vaccination or exposure to a live or attenuated vaccine within the 6 weeks prior to
the first dose of study drug, or who are expected to be vaccinated or to have
household exposure to these vaccines during treatment or during the 6 weeks following
discontinuation of study drug.
- Participants having received azathioprine, 6-mercaptopurine, methotrexate,
thioguanine, infliximab, adalimumab, golimumab, interferon, cyclosporine,
mycophenolate, tacrolimus, IV or rectally administered corticosteroids, natalizumab,
vedolizumab, other antiadhesion molecules, or investigational drugs during the
specified time periods prior to baseline whereby they may still have pharmacokinetic
and/or pharmacodynamic effect in the body of the participant.
- Previous treatment by leukocyte apheresis including selective lymphocyte, monocyte, or
granulocyte apheresis, or plasma exchange within 6 months prior to baseline.
- Treatment by specified prohibited concomitant medications, including moderate to
potent CYP3A inducers or inhibitors in the specified time periods prior to the first
dose of study drug or are expected to receive any of these medications during the
- Chronic and frequent use of antimotility agents for control of diarrhea (ie,
diphenoxylate hydrochloride with atropine sulfate or loperamide).
- History of bowel surgery, including cholecystectomy within 6 months prior to baseline,
history of appendectomy within 3 months prior to baseline, or significant trauma or
major surgery within 4 weeks of screening visit are excluded.
- Participants with the following laboratory values at screening:
- Hemoglobin level lower than 9.0 g/Dl.
- Absolute white blood cell (WBC) count lower than 3000/mm3.
- Absolute neutrophil count lower than 1200/mm3.
- Absolute lymphocyte count lower than 750/mm3.
- Thrombocytopenia as defined by a platelet count lower than 100,000/mm3.
- Estimated bedside Schwartz Glomerular filtration rate (GFR) lower or equal to 40
- Total bilirubin, aspartate aminostransferase (AST) or alanine aminotransferase
(ALT) more than 1.5 times the upper limit of normal.
- Positive stool examinations for enteric pathogens, pathogenic ova or parasites, or C.
difficile toxin at screening.
- Participants infected with human immunodeficiency virus (HIV) or hepatitis B or C
- History of more than one episode of HZ, a history of disseminated HZ or disseminated
- History or current symptoms of any lymphoproliferative disorder (eg, Epstein Barr
Virus (EBV) related lymphoproliferative disorder, lymphoma, leukemia,
myeloproliferative disorders, multiple myeloma, or signs and symptoms suggestive of
currently lymphatic disease).
- Clinically significant infections currently or within 3 months prior to baseline (eg,
those requiring hospitalization or parenteral antimicrobial therapy or opportunistic
infections), a history of any infection requiring antimicrobial therapy within 2 weeks
of baseline, or a history of any infection otherwise judged by the investigator to
have the potential for exacerbation by participation in the study.
- Any malignancies or with a history of malignancies, with the exception of adequately
treated or excised nonmetastatic basal cell or squamous cell cancer of the skin.
- Investigator site staff members directly involved in the conduct of the study and
their family members, site staff members otherwise supervised by the investigator, or
participants who are employees of the Sponsor, including their family members,
directly involved in the conduct of the study.
- Participation in other studies involving investigational drug(s) within 2 months prior
to study entry and/or during study participation.
- Other acute or chronic medical or psychiatric condition including recent (within the
past year) or active suicidal ideation or behavior or laboratory abnormality that may
increase the risk associated with study participation or study intervention
administration or may interfere with the interpretation of study results and, in the
judgment of the investigator, would make the participant inappropriate for entry into
- Pregnant female participants; breastfeeding female participants; fertile female
participants of childbearing potential who are unwilling or unable to use a highly
effective method of contraception as outlined in this protocol for the duration of the
study and through the telephone follow up visit.
