- •101 Subject has provided informed consent prior to initiation of study.
- •102 Age =18 years to <80 years at screening visit, except in South Korea where age =19 years to <80 years at screening visit.
- •103 Diagnosis of UC established =3 months prior to enrollment by clinical and endoscopic evidence and corroborated by a histopathology report.
- •104 Moderately to severely active UC as defined by a modified Mayo
- •score of 5 to 9, with a centrally read endoscopy subscore =2.
- •105 Has documentation of
- •- A surveillance colonoscopy within 12 months of day 1 visit for subjects with pancolitis of at least 8 years duration, or subjects with left-sided colitis of over 12 years duration, or subjects with
- •primary sclerosing cholangitis.
- •For all other subjects, up-to-date colorectal cancer surveillance. At the discretion of the investigator, a colonoscopy may be performed as the screening endoscopy for this study. Subjects who do not have a colonoscopy report available in source documentation will have a
- •colonoscopy instead of rectosigmoidoscopy performed as the screening endoscopy for the study.
- •106 Subjects must have demonstrated inadequate response, loss of response, or intolerance to at least 1 conventional therapy, biologic therapy, or targeted small molecule therapy (ie, JAK-inhibitor).
- •1. Conventional therapy failed subjects:
- •- Corticosteroids (corticosteroid-refractory colitis, defined as signs
- •and/or symptoms of active UC despite oral prednisone (or equivalent) at doses of at least 30 mg/day for a minimum of 2 weeks; or corticosteroid-dependent colitis, defined as: an inability to reduce
- •corticosteroids below the equivalent of prednisone 10 mg/day within
- •3 months of starting corticosteroids without a return of signs and/or
- •symptoms of active UC; or a relapse within 3 months of completing a
- •course of corticosteroids
- •- History of intolerance of corticosteroids
- •- Immunomodulators: signs and/or symptoms of persistently active
- •disease despite at least 3 months treatment with one of the following at locally approved doses: oral azathioprine or 6-mercaptopurine, or oral azathioprine or 6-mercatopurine within a therapeutic range as judged by thioguanine metabolite testing, or a combination of a thiopurine and allopurinol within a therapeutic range as judged by thioguanine metabolite testing
- •- History of intolerance to at least 1 immunomodulator (including but not limited to nausea/vomiting, abdominal pain, pancreatitis, liver function test abnormalities, and lymphopenia) and have neither failed nor demonstrated an intolerance to a biological medication (anti-TNF antibody, anti-integrin antibody, or IL-12/23 antagonists) that is indicated for the treatment of UC
- •2. Biologic or targeted small molecule therapy failed subjects: those who demonstrated inadequate response or loss of response or intolerance to biologic therapy for UC (eg, anti-TNF antibodies or IL-12/23 antagonists, anti-integrin antibodies) or targeted small molecules (eg, JAK inhibitors or S1P modulators). The therapy used to qualify the subject for entry into this category must be approved for the treatment of UC in the country of use, at the time of use. Subjects must fulfil one of the following criteria:
- •- Inadequate response: signs and symptoms of persistently active
- •disease despite induction treatment at the approved induction dosing that was indicated in the product label at the time of use
- •- Loss of response: recurrence of signs and symptoms of active
- •disease during approved mainten

- •201 Diagnosis of Crohn’s disease, inflammatory bowel disease-unclassified, microscopic colitis, ischemic colitis, or clinical findings suggestive of Crohn’s disease.
- •202 Disease limited to the rectum.
- •203 Evidence of toxic megacolon, fulminant colitis, intra-abdominal abscess, or stricture/stenosis within the small bowel or colon.
- •204 Previous bowel resection or intestinal or intra-abdominal surgery.
- •Have had extensive surgery for UC, or are likely to require surgery for the treatment of UC during the study. Subjects who have had limited surgery for UC may be allowed in the study, if this does not affect the assessment of efficacy. Discussion with the sponsor must occur prior to screening of such subjects.
- •Have had any small bowel or colonic surgery within 6 months of day 1.
- •Have had any nonintestinal intra-abdominal surgery within 3 months of day 1.
- •205 Adenoma and dysplasia exclusion criteria:
- •Any current sporadic adenoma without dysplasia that has not been removed. Once completely removed, the subject is eligible for study.
- •Dysplasia occurring in flat mucosa, sporadic adenomas containing dysplasia, and dysplasia-associated lesions or masses will be managed as follows:
- •Any history or current evidence of high-grade dysplasia.
- •Any history or current evidence of dysplasia occurring in flat mucosa.
- •This includes histopathology reporting indefinite for dysplasia, low-grade dysplasia, and high-grade dysplasia.
- •Any history or current evidence of a nonadenoma-like
- •dysplasia-associated lesions or masses, with or without evidence of
- •Any current sporadic adenoma containing dysplasia or any current
- •adenoma-like dysplasia-associated lesions or masses that has not been
- •removed. Once completely removed, the patient is eligible for the study.
- •206 Stool positive for Clostridium difficile toxin at screening and other enteric pathogens including but not limited to ova, parasites, Campylobacter, salmonella, shigella, E coli 0157:H7, and Yersinia enterocolitica.
- •207 History or evidence of suicidal ideation (severity of 4 or 5) or any suicidal behavior based on an assessment with the Columbia Suicide Severity Rating Scale (C-SSRS) at screening
- •208 Active infection for which anti-infectives were indicated within 2
- •weeks prior to screening visit OR presence of serious infection, defined as requiring hospitalization or intravenous (IV) anti-infectives within 8 weeks prior to screening visit.
- •209 Active tuberculosis or latent tuberculosis with no documented past history of adequate treatment per local standard of care
- •210 Positive test for TB during screening defined as: either a positive or indeterminate QuantiFERON-TB or T-spot test OR positive purified protein derivative. Subjects with a positive PPD and a history of Bacillus Calmette-Guerin vaccination are allowed to enroll with a negative QuantiFERON®-TB or T-Spot test and negative chest X-ray.
- •Indeterminate QuantiFERON®-TB or T-spot test can be repeated once,
- •based on investigator judgment. Subjects can enroll if second result is
- •negative. Subjects with persistent indeterminate or positive test results must proceed as below.
- •Subjects with a positive PPD test or a positive or indeterminate QuantiFERON®-TB or T-Spot test are allowed to enroll if they meet ALL the following criteria at screening:
- •No symptoms per tuberculosis worksheet provided by Amgen
- •documented history of adequate TB treatment or prophylactic treatment for latent TB
- •No known exposure to a case of active tuberculosis after mo
