- •2. Ability to provide written informed consent or assent and to be compliant with the schedule of protocol assessments
- •3. Diagnosed with UC = 3 months prior to screening confirmed by endoscopic and histologic evidence
- •4. Active UC confirmed by endoscopy with = 10 cm rectal involvement. Subjects with proctitis only at baseline who meet the other eligibility criteria for inclusion, including the endoscopic and rectal bleeding criteria for moderate to severe disease,will be capped at 15% of the total subjects enrolled
- •5. Moderately to severely active UC defined as MMS of 4 to 9, including an ES of = 2 and RB score = 1
- •6. Received a surveillance colonoscopy within 12 months before baseline to rule out dysplasia in subjects with pancolitis > 8 years duration or subjects with left-sided colitis > 12 years duration. Subjects without a surveillance colonoscopy within the prior 12 months will have a
- •colonoscopy at screening (ie, in place of screening proctosigmoidoscopy). Any adenomatous polyps must be removed prior to their first dose of study treatment
- •7. Demonstrated an inadequate response to, loss of response to, or intolerance to at least 1 of the following therapies as defined below:
- •Conventional therapy
- •a. Corticosteroids
- •b. Thiopurines
- •Biologic therapy or JAK inhibitor therapy
- •a. Antitumor necrosis factor alpha (TNFa) antibodies (eg, infliximab,adalimumab, golimumab, or biosimilars)
- •b. Anti-integrin antibodies (eg, vedolizumab)
- •c. Interleukin 12/23 antibodies (eg, ustekinumab)
- •d. JAK inhibitors (eg, tofacitinib)
- •8. Subjects are permitted to be receiving a therapeutic dose of the following drugs:
- •Oral 5 ASA compounds provided the dose has been stable for = 2
- •weeks immediately prior to randomization
- •Oral corticosteroid therapy (prednisone at a stable dose = 20 mg/day,budesonide at a stable dose = 9 mg/day, or equivalent steroid) provided the dose has been stable for the 4 weeks immediately prior to the screening endoscopy assessment
- •Immunosuppressive agents such as oral azathioprine or 6 mercaptopurine must be discontinued = 2 weeks prior to randomization
- •Probiotics (eg, Culturelle®, Saccharomyces boulardii) provided the dose has been stable for the 2 weeks immediately prior to randomization
- •Antidiarrheals (eg, loperamide, diphenoxylate with atropine) for control of chronic diarrhea
- •If oral 5-ASA or corticosteroids have been recently discontinued, they must have been stopped for at least 2 weeks prior to the endoscopy used for the baseline MMS.
- •9. Adequate hematological function defined by white blood cell count = 3.5 × 109/L with absolute neutrophil count (ANC) = 1.5 × 109/L,lymphocyte count = 0.8 × 109/L, platelet count = 100 × 109/L, and hemoglobin = 8 g/dL
- •10. Adequate hepatic function defined by a total bilirubin level = 1.5 × the upper limit of normal (ULN) range and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels =2.0 × ULN. Subjects with an isolated total bilirubin and normal AST and ALT diagnosed with Gilbert's syndrome may participate
- •11. Adequate renal function defined by an estimated glomerular filtration rate = 30 mL/min/1.73 m2 by the Chronic Kidney Disease Epidemiology Collaboration equation at screening
- •12. Females must meet either a or b of the following criteria and males
排除标准
- •1. Severe extensive colitis as evidenced by:
- •Physician judgment that the subject is likely to require hospitalization for medical care or surgical intervention of any kind for UC (eg,colectomy) within 12 weeks of baseline
- •Current evidence of fulminant colitis, toxic megacolon or recent history (within last 6 months) of toxic megacolon, or bowel perforation
- •Previous total or partial colectomy
- •2. Diagnosis of Crohn's disease (CD) or indeterminate colitis or the presence or history of a fistula consistent with CD
- •3. Diagnosis of microscopic colitis, ischemic colitis, or infectious colitis
- •4. Hospitalization for exacerbation of UC requiring IV steroids within 12 weeks of screening
- •5. Positive assay or stool culture for pathogens or positive test for
- •Clostridioides difficile toxin at screening
- •6. Pregnancy, lactation, or a positive serum ß hCG measured during
- •7. Clinically relevant neurological, endocrine, metabolic, psychiatric,cognitive impairment, alcohol/drug abuse/dependence, or other major systemic disease making implementation of the protocol or
- •interpretation of the study difficult or would put the subject at risk
- •8. Have any of the following conditions or receiving treatments that may affect cardiovascular function:
- •Myocardial infarction, unstable angina, stroke/transient ischemic attack,decompensated heart failure requiring hospitalization or Class III/IV heart failure within 6 months of the Screening Visit

- •Start, stop, or change in dosage of any anti-arrhythmic drugs (Class I to IV) within 1 week of randomization
- •9. Forced expiratory volume at 1 second (FEV1) or forced vital capacity (FVC) < 70% of predicted values and FEV1/FVC ratio < 0.70 at screening
- •10. Uncontrolled diabetes as determined by hemoglobin A1c (HbA1c) > 9% at screening, or subjects with diabetes with significant comorbid conditions such as retinopathy
- •11. History of macular edema or retinopathy
