Summary

"This trial is testing a new drug, GS-1427, to see if it is safe and effective in treating people with moderate to severe ulcerative colitis. The study will compare different groups of

Who is the study for?
This trial is for individuals who have had Ulcerative Colitis for at least 90 days, confirmed by previous tests. They should have moderate to severe symptoms and not responded well or tolerated at least one standard treatment like corticosteroids or azathioprine.
What is being tested?
The study tests if GS-1427 can effectively treat Ulcerative Colitis compared to a placebo. It also compares the effectiveness of combining GS-1427 with ustekinumab versus using each drug alone in achieving a clinical response after 12 weeks.
What are the potential side effects?
Potential side effects may include typical reactions associated with immune-modulating drugs such as injection site reactions, increased risk of infections, possible liver issues, and flu-like symptoms among others.

Trial Design

4Treatment groups
Experimental Treatment
Group I: Part A, Placebo; Part B, Part C: GS-1427Experimental Treatment2 Interventions
Participants will receive Placebo to match GS-1427 Day 1 through Week 12 (Part A). Part A placebo participants will be eligible to undergo re-randomization in a double-blind manner after endoscopy assessment at Week 12 to receive one of the GS-1427 dose A, B, or C treatments. Participants will be eligible to continue and remain on the new dose through Week 52 (Part B). Participants who complete Part B of the study will continue onto Part C: blinded treatment extension for an additional 24 weeks (through Week 76).
Group II: Part A, Part B, Part C: GS-1427 Dose CExperimental Treatment1 Intervention
Participants will receive GS-1427 Dose C Day 1 through Week 12 (Part A). Participants who complete the 12-week Part A treatment period will be eligible to continue and remain on the same dose of GS-1427 through Week 52 (Part B). Participants who complete Part B of the study will continue onto Part C: blinded treatment extension for an additional 24 weeks (through Week 76).
Group III: Part A, Part B, Part C: GS-1427 Dose BExperimental Treatment1 Intervention
Participants will receive GS-1427 Dose B Day 1 through Week 12 (Part A). Participants who complete the 12-week Part A treatment period will be eligible to continue and remain on the same dose of GS-1427 through Week 52 (Part B). Participants who complete Part B of the study will continue onto Part C: Blinded treatment extension for an additional 24 weeks (through Week 76).
Group IV: Part A, Part B, Part C: GS-1427 Dose AExperimental Treatment1 Intervention
Participants will receive GS-1427 Dose A Day 1 through Week 12 (Part A). Participants who complete the 12-week Part A treatment period will be eligible to continue and remain on the same dose of GS-1427 through Week 52 (Part B). Participants who complete Part B of the study will continue onto Part C: Blinded treatment extension for an additional 24 weeks (through Week 76).
