A tiered strategy was used to detect and characterize etrolizumab antibodies within this clinical study. When determining post baseline incidence, participants were considered to be ADA positive if they were ADA negative or had missing data at baseline but developed an ADA response following etrolizumab drug exposure (treatment-induced ADA response), or if they were ADA positive at baseline and the titer of one or more post baseline samples was at least 0.60 titer unit greater than the titer of the baseline sample (treatment-enhanced ADA response). Participants were considered to be ADA negative if they were ADA negative or had missing data at baseline and all post baseline samples were negative, or if they were ADA positive at baseline but did not have any post baseline samples with a titer that was at least 0.60 titer unit greater than the titer of the baseline sample (treatment unaffected).
- Etrolizumab Serum Trough Concentration (for Arms/Timepoints Above LLOQ) [Pre-dose (0 hour) at Baseline and Weeks 14, 24, 44 and 66]

Outcome Measures
Title | Induction Phase: Percentage of Participants With Remission at Week 14, as Determined by the Mayo Clinic Score (MCS) |
---|---|
Description | The Mayo Clinic Score (MCS) ranges from 0 to 12 and is a composite of 4 assessments (each rated from 0-3): stool frequency, rectal bleeding, endoscopy, and physician's global assessment. Higher scores represent greater disease severity. Remission was defined as MCS less than or equal to (≤)2 with individual subscores ≤1 and a rectal bleeding subscore of 0. |

Title | Induction Phase: Change From Baseline to Week 6 in MCS Rectal Bleed Subscore |
---|---|
Description | Rectal bleeding data were collected via the participant's diaries and each day a participant provided a score from 0 to 3 according to the following definitions: 0 = no blood in the stool; 1 = streaks of blood with stool less than half the time; 2 = obvious blood with stool most of the time; 3 = blood alone passed. The Mayo Clinic Score (MCS) rectal bleeding subscore was calculated as the worst value of three days of daily diary scores closest to anchor dates at baseline and post-baseline. The data was considered non-parametric and was reported using RANK analysis of covariance (ANCOVA). Participants were stratified by concomitant treatment with corticosteroids or immunosuppressants at randomization and disease activity measured during screening (MCS ≤9/MCS ≥10); the model adjusted for these stratification factors along with the baseline rectal bleeding (RB) subscore. |

Title | Number of Participants With Anti-Therapeutic Antibodies to Etrolizumab at Baseline and During the Study |
---|---|
Description | A tiered strategy was used to detect and characterize etrolizumab antibodies within this clinical study. When determining post baseline incidence, participants were considered to be ADA positive if they were ADA negative or had missing data at baseline but developed an ADA response following etrolizumab drug exposure (treatment-induced ADA response), or if they were ADA positive at baseline and the titer of one or more post baseline samples was at least 0.60 titer unit greater than the titer of the baseline sample (treatment-enhanced ADA response). Participants were considered to be ADA negative if they were ADA negative or had missing data at baseline and all post baseline samples were negative, or if they were ADA positive at baseline but did not have any post baseline samples with a titer that was at least 0.60 titer unit greater than the titer of the baseline sample (treatment unaffected). |
