MeasureTime frameDescription
Induction Period Primary Endpoint: Percentage of Participants With Clinical Remission Per Full Mayo Score (FMS) at Week 8Week 8The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The FMS ranges from 0 (normal or inactive disease) to 12 (severe disease) and is calculated as the sum of 4 subscores (stool frequency, rectal bleeding, endoscopy \[confirmed by a central reader\], and physician's global assessment), each of which ranges from 0 (normal) to 3 (severe disease). Negative changes indicate improvement. Clinical remission per FMS is defined as Mayo Score ≤ 2 and no individual subscore \> 1.

Participant flow

Recruitment details

This study included a Main Study (120 sites in 19 countries) and a Japan Sub-Study (22 sites in Japan). After a 3-week screening period, participants were randomized 3:2 to an 8-week double-blind (DB) Induction Period with 2 adalimumab dosing regimens (Induction Standard Dose \[I-SD\] or Induction Higher Dose \[I-HD\]).

Pre-assignment details

At Week 8, participants in Main Study were re-randomized (2:2:1) into 44-week DB Maintenance Period with 3 adalimumab dosing regimens (M-SD, M-HD, or an exploratory Therapeutic Drug Monitoring \[TDM\] Regimen). Participants in Japan Sub-study were re-randomized (1:1) into 44-week DB Maintenance Period with 2 adalimumab dosing regimens (M-SD, M-HD).

Induction Period Ranked Secondary Endpoint 3: Percentage of Participants With Inflammatory Bowel Disease Questionnaire (IBDQ) Response (Increase of IBDQ ≥ 16 From Baseline) at Week 8

The IBDQ is a self-administered 32-item questionnaire to evaluate quality of life across 4 dimensional scores: bowel, systemic, social and emotional. Responses to each question range from 1 (severe problem) to 7 (normal health). Total IBDQ score is the sum of the responses to the individual IBDQ questions, and ranges from 32 to 224 with higher scores indicating a better quality of life.

Maintenance Period Ranked Secondary Endpoint 8: Percentage of Week 8 Responders (Per FMS) With IBDQ Response (Increase of IBDQ ≥ 16 From Baseline) at Week 52

The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The FMS ranges from 0 (normal or inactive disease) to 12 (severe disease) and is calculated as the sum of 4 subscores (stool frequency, rectal bleeding, endoscopy \[confirmed by a central reader\], and physician's global assessment), each of which ranges from 0 (normal) to 3 (severe disease). Negative changes indicate improvement. Week 8 responders are defined as participants with a decrease in FMS of ≥ 3 points and ≥ 30% from Baseline plus a decrease in the rectal bleeding subscore (RBS) ≥ 1 or an absolute RBS ≤ 1. The IBDQ is a self-administered 32-item questionnaire to evaluate quality of life across 4 dimensional scores: bowel, systemic, social and emotional. Responses to each question range from 1 (severe problem) to 7 (normal health). Total IBDQ score is the sum of responses to the individual IBDQ questions, and ranges from 32 to 224 with higher scores indicating a better quality of life.
