Study to Evaluate the Efficacy and Safety of Filgotinib in the Induction and Maintenance of Remission in Adults With Moderately to Severely Active Ulcerative Colitis
Purpose
The primary objectives of this study are to evaluate the efficacy of filgotinib in the induction and maintenance treatment of moderately to severely active ulcerative colitis (UC) in participants who are biologic-naive and biologic-experienced. Participants who complete the study, or met protocol specified efficacy discontinuation criteria will have the option to enter a separate, long-term extension (LTE) study (Gilead Study GS-US-418-3899: NCT02914535).

Inclusion Criteria
- Males or non-pregnant, non-lactating females, ages 18 to 75 years, inclusive based on the date of the screening visit - Documented diagnosis of UC of at least 6 months AND with a minimum disease extent of 15 cm from the anal verge. Documentation should include endoscopic and histopathologic evidence of UC. - A surveillance colonoscopy is required at screening in individuals with a history of UC for 8 or more years, if one was not performed in the prior 24 months - Moderately to severely active UC - Previously demonstrated an inadequate clinical response, loss of response to, or intolerance to at least 1 of the following agents (depending on current country treatment recommendations/guidelines): corticosteroids, immunomodulators, tumor necrosis factor alpha (TNFa) antagonists, or vedolizumab

|
Experimental Maintenance Study: Filgotinib 200 mg From Induction Filgotinib 200 mg |
Participants in the Filgotinib 200 mg arm who completed the Induction Study and achieved either Endoscopy/Bleeding/Stool Frequency (EBS) remission or Mayo Clinic Score (MCS) response at Week 10 were re-randomized at Week 11 into the Maintenance Study to receive filgotinib 200 mg and PTM filgotinib 100 mg for an additional 47 weeks (up to Week 58). |
|
Placebo Comparator Maintenance Study: Placebo From Induction Filgotinib 200 mg |
Participants in the Filgotinib 200 mg arm who completed the Induction Study and achieved either EBS remission or MCS response at Week 10 were re-randomized at Week 11 into the Maintenance Study to receive PTM filgotinib orally once daily for an additional 47 weeks (up to Week 58). |
|
Experimental Maintenance Study: Filgotinib 100 mg From Induction Filgotinib 100 mg |
Participants in the Filgotinib 100 mg arm who completed the Induction Study and achieved either EBS remission or MCS response at Week 10 were re-randomized at Week 11 into the Maintenance Study to receive filgotinib 100 mg and PTM filgotinib 200 mg for an additional 47 weeks (up to Week 58). |
|
Placebo Comparator Maintenance Study: Placebo From Induction Filgotinib 100 mg |
Participants in the Filgotinib 100 mg arm who completed the Induction Study and achieved either EBS remission or MCS response at Week 10 were rerandomized at Week 11 into the Maintenance Study to receive PTM filgotinib orally once daily for an additional 47 weeks (up to Week 58). |
|
Placebo Comparator Maintenance Study: Placebo From Induction Placebo |
Participants in the Placebo arm who completed the Induction Study and achieved either EBS remission or MCS response at Week 10 were re-randomized at Week 11 into the Maintenance Study to receive PTM filgotinib for an additional 47 weeks (up to Week 58). |
