Study Endpoints
Primary Endpoints
Percentage of participants who experienced an adverse event
Week 96

Incidence of treatment-emergent adverse events (TEAEs) as measured over time.

Part A: Change in Robarts Histopathology Index (RHI)
Week 12

Change in Robarts Histopathology Index (RHI) from baseline at Week 12 will be assessed. The RHI is used to quantify and assess histological activity of UC, comprising of scores for inflammatory infiltrates, neutrophils, erosions or ulceration. Scores are assigned to each of these features, with a total ranging from 0 (no disease activity) to 33 (most severe disease activity). Higher score indicates more severe disease.

Part B: Percentage of participants with clinical remission
Week 12

Percentage of participants with clinical remission at Week 12 will be assessed. Clinical remission is based on the modified Mayo subscores, which consist of a rectal bleeding subscore (ranging from 0 to 3), stool frequency subscore (ranging from 0 to 3), and endoscopic subscore (ranging from 0 to 3), as assessed by central reading. Higher scores indicate more severe disease.
