Inclusion criteria

* Confirmed diagnosis of moderate to severe (Part A) or mild to moderate (Part B) UC for ≥3 months prior to baseline. * Active disease beyond the rectum (\>15 cm of active disease from the anal verge at the screening endoscopy). Part A (moderate to severe): Must have a 5 to 9 score on the modified mayo score, including an endoscopy subscore of at least 2. Part B (mild to moderate): Participants with mMS of 4 to 6, ES of ≥2 and RB score of ≥1 * Must have inadequate response to, loss of response to, or intolerance to at least one conventional therapy for UC. * Total body weight \>40 kg (88.2 lb).

Exclusion criteria

* Presence of indeterminate; microscopic; ischemic; infectious; radiation colitis; diverticular disease; Crohn's disease; colonic stricture; colonic obstruction/ resection; presence of cancer. * History of bowel surgery within 6 months prior to baseline. * History of significant trauma or major surgery within 4 weeks of screening or considered in imminent need of surgery or with elective surgery scheduled to occur during the study. * Presence of clinical signs of fulminant colitis or toxic megacolon, primary sclerosing cholangitis and evidence of colonic dysplasia, adenomas or neoplasia. * Clinically significant infections within 6 months of baseline

Design outcomes

Primary

MeasureTime frameDescription
Part A: Proportion of participants achieving clinical remission at Week 12 in participants with moderate to severe UC.Week 12Clinical remission based on modified Mayo Score is defined as endoscopic subscore equal 0 or 1 (without friability), stool frequency subscore equal 0 or 1, and rectal bleeding subscore equal 0
Part B: Percent change from baseline in the mMS in participants with mild to moderate UC.Week 12

Secondary

MeasureTime frameDescription
Part A: Proportion of participants achieving improvement in endoscopic appearance at Week 12Week 12Endoscopic improvement is defined as a Mayo endoscopic subscore of ≤1 (without friability)
Part A: Proportion of participants with clinical remission at Week 12Week 12Clinical Remission defined by Total Mayo Score ≤2 and no individual subscore \>1 and rectal bleeding subscore of 0
Part B: Proportion of participants achieving clinical remission at Week 12Week 12Clinical Remission based on modified Mayo Score is defined as endoscopic subscore 0 or 1 (without friability), stool frequency subscore 0 or 1, and rectal bleeding subscore 0.
