Phase 3
Completed
Conditions
Ulcerative Colitis
Interventions
Other: Placebo (IV)
Other: Placebo (Injection)
Registration Number
NCT02136069
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This is a multicenter, Phase III, randomized, double-blind, double-dummy, parallel-group study to evaluate the safety, efficacy, and tolerability of etrolizumab compared with infliximab in treating participants with moderate to severe ulcerative colitis (UC) who are naive to tumor necrosis factor (TNF) inhibitors. Participants will be randomized in a 1:1 ratio to receive either etrolizumab 105 milligrams (mg) by subcutaneous (SC) injection once every 4 weeks (Q4W) + placebo (intravenous \[IV\] infusion at Weeks 0, 2, and 6, then once every 8 weeks \[Q8W\]) or infliximab 5 milligrams/kilogram (mg/kg) IV at Weeks 0, 2, and 6, then Q8W) + placebo (SC Q4W). Time on treatment is 54 weeks.

Number of Participants With Adverse Events Leading to Study Drug DiscontinuationBaseline until the end of study (up to 66 weeks)
Number of Participants With Infection-Related Adverse Events, Severity Determined According to the NCI CTCAE v4.0Baseline until the end of study (up to 66 weeks)

All AEs were graded for severity using the NCI-CTCAE v4.0. Any AE not specifically listed was assessed per the following 5 grades: Grade 1 = mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; or intervention not indicated. Grade 2 = moderate; minimal, local, or non-invasive intervention indicated; or limiting age-appropriate instrumental activities of daily living. Grade 3 = severe or medically significant, but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; or limiting self-care activities of daily living. Grade 4 = life-threatening consequences or urgent intervention indicated. Grade 5 = death related to AE. Not all grades are appropriate for all AEs; some AEs have fewer than 5 options. The terms "severe" and "serious" are not synonymous and are independently assessed for each AE. Multiple occurrences of AEs were counted only once per participant at the highest (worst) grade.

Number of Participants With Anti-Therapeutic Antibodies (ATAs) to EtrolizumabWeeks 0, 4, 10, 12, 30, and 54
Change From Baseline in Inflammatory Bowel Disease Questionnaire (IBDQ) Overall Score at Weeks 10, 30, and 54Weeks 10, 30, and 54

The IBDQ is used to assess participant's health-related quality of life (QOL). The 32-item questionnaire contains four domains: bowel symptoms (10 items), systemic symptoms (5 items), emotional function (12 items), and social function (5 items). The items are scored on a 7-point Likert scale with a higher score indicating better health-related QOL.

IBDQ score is a total score summed up from across all 32 questions on the questionnaire. The score can range from 32-224 and the higher score indicates a better quality of life.
