Inclusion Criteria

Participants are eligible to be included in the study only if all the following criteria apply

AGE and WEIGHT

Participant must be 18 years of age or older and >40kg at the time of signing the informed consent.

TYPE OF PARTICIPANT AND DISEASE CHARACTERISTICS

Participants who have a:

Diagnosis of ulcerative colitis, established at least 3 months prior to screening, as documented by diagnostic sigmoidoscopy or colonoscopy, and biopsy.

Complete Mayo Score of 6 to 12, with disease extending >=15cm from the anal verge, with a centrally read endoscopic subscore of >=2 at screening endoscopy, and a rectal

bleeding subscore >=1.

A history of at least one of the following:

Inadequate response to, loss of response to, or intolerance to azathioprine or mercaptopurine (including thiopurine methyltransferase (TPMT) genetic

mutation precluding use), ciclosporin, tacrolimus or methotrexate.

Inadequate response to, intolerance to, or demonstrated dependence on oral corticosteroids.

Inadequate response to, loss of response to, or intolerance to one biologic class ONLY for the treatment of UC: either one or more anti-TNF therapies

(e.g. infliximab, adalimumab, golimumab, or biosimilar) OR vedolizumab.

Surveillance colonoscopy (performed according to local standards) within 12 months of screening (or during screening, if required) for participants with:

Pancolitis of >8 years duration; or

Patients with left-sided colitis of >12 years duration; or

Patients with primary sclerosing cholangitis.

For patients for whom this criterion does not apply, colorectal cancer surveillance should be undertaken according to local or national guidelines for patients with age >=50, or with other known risk factors for colorectal

cancer.

SEX

Female participants:

A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:

Not a woman of childbearing potential (WOCBP), see Section 10.4.1,

WOCBP definitions.

OR

A WOCBP who agrees to use a highly effective contraceptive method for at least 4 weeks prior to dosing, until the Follow-Up visit. See Section 10.4.2, Contraceptive Guidance.

INFORMED CONSENT

Capable of giving signed informed consent as described in Section 10.1.3 which includes compliance with the requirements and restrictions listed in the informed consent form

(ICF) and in this protocol.

Exclusion Criteria

Participants with a current diagnosis of indeterminate colitis, inflammatory bowel

disease-unclassified, Crohnâ??s disease, infectious colitis, or ischaemic colitis.

Participants with fulminant ulcerative colitis (as defined by 6 bloody stools daily

AND 1 or more of: i) body temperature >=100.4°F (or 38°C) or ii) heart rate >90 beats

per minute), or toxic megacolon.

Prior extensive colonic resection, subtotal or total colectomy, or proctocolectomy, or

planned surgery for UC.

Participants with any uncontrolled medical conditions, other than active UC, that in

the opinion of the investigator put the participant at unacceptable risk or interfere

with study assessments or integrity of the data. Other medical conditions should be

stable at the time of screening and be expected to remain stable for the duration of

the study.

Unstable lifestyle factors, such as alcohol use to excess or recreational drug use, to

the extent that in the opinion of the investigator they would interfere with the ability

of a participant to complete the study.

An active infection or a history of serious infections as follows:

- Use of antimicrobials (antibacterials, antivirals, antifungals or antiparasitic agents)

for an infection within 30 days before first dose (topical treatments may be

allowed at the Medical Monitorâ??s discretion).

- A history of opportunistic infections within 1 year of screening (e.g. Pneumocystis

jirovecii, aspergillosis or CMV colitis). This does not include infections that may

occur in immunocompetent individuals, such as fungal nail infections or vaginal

candidiasis, unless it is of an unusual severity or recurrent nature.

- Recurrent or chronic infection or other active infection that, in the opinion of the

Investigator, might cause this study to be detrimental to the patient.

- Symptomatic herpes zoster within 3 months prior to screening.

- History of tuberculosis (active or latent), irrespective of treatment status.

- A positive diagnostic TB test at screening (defined as a positive QuantiFERON

test). In cases where the QuantiFERON test is indeterminate, the participant may

have the test repeated once and if their second test is negative they will be

eligible. In the event a second test is also indeterminate, the investigator has the

option to undertake PPD testing. If the PPD reaction is <5 mm, then the

participant is eligible. If the reaction is >=5 mm, or PPD testing is not undertaken,

the participant is not eligible.

- Positive Clostridium difficile toxin test during screening. However, rescreening

can be undertaken following successful treatment.

Current or history of chronic liver or biliary disease (with the exception of Gilbertâ??s

syndrome, asymptomatic gallstones or uncomplicated fatty liver disease).

Hereditary or acquired immunodeficiency disorder, including immunoglobulin

deficiency (unless the participant has a documented history of selective IgA

deficiency).

A major organ transplant (e.g. heart, lung, kidney, liver, pancreas) or haematopoietic

stem cell/marrow transplant.

Any planned major surgical procedure during the study.

A history of malignant neoplasm within the last 5 years, except for adequately
