Conditions

a chronic relapsing and remitting gastrointestinal disorder causing inflammation of the colonic and rectal mucosa., Ulcerative Colitis is a type of inflammatory bowel disease

Brief summary

Clinical remission at Week 12, defined as an MMS ≤ 2, with ES of ≤ 1 (excluding friability), a rectal bleeding (RB) subscore of 0, stool frequency (SF) subscore of ≤ 1 (with a ≥ 1 point decrease from baseline).
