Study Endpoints

Primary Endpoints

Proportion of Participants Achieving Clinical Response Per Modified Mayo Clinic Score at Week 12
Week 12

Clinical Response is defined as a decrease from baseline of ≥ 2 points and at least 30% in 3 components of the modified Mayo Clinic Score, Stool Frequency, Rectal Bleeding, and Endoscopic Findings, in addition to a ≥ 1 point decrease from baseline in the Rectal Bleeding subscore or Rectal Bleeding subscore of ≤ 1. The modified Mayo Clinic Score is a scoring system for assessment of UC activity and is composed of subscores from endoscopy (range: 0 to 3, where 0 = normal or inactive disease and 3 = severe disease \[spontaneous bleeding, ulceration\]), rectal bleeding (range: 0 to 3, where 0 = no blood seen and 3 = blood alone passes), and stool frequency (range: 0 to 3, where 0 = normal number of stools and 3 = at least 5 or more stools more than normal). Total score for modified Mayo Clinic Score ranges from 0 to 9 (sum of all subscores), with higher scores indicating higher disease activity.
