Research summary
This research study is being done to see if guselkumab, golimumab or the combination of guselkumab and golimumab is safe and effective for treating participants with moderately to severely active ulcerative colitis.
Guselkumab is currently in phase 3 studies for both Crohn’s disease and ulcerative colitis. It is not approved for the treatment of ulcerative colitis at this time by any Regulatory Authority in any country.
Golimumab has been approved in countries worldwide for the treatment of moderately to severely active ulcerative colitis, rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis.
The combination of guselkumab and golimumab works by blocking both IL-23 and TNF, chemical messengers that regulate inflammation and are present in excessive amounts in patients with active ulcerative colitis. This combination has been studied in ulcerative colitis and is currently being studied in psoriatic arthritis. The combination of guselkumab and golimumab is not yet approved for ulcerative colitis by any Regulatory Authority in any country.
Participants will randomly be put into 1 of the 6 treatment groups. These groups include a placebo, guselkumab, golimumab, combination of guselkumab and golimumab (high dose), combination of guselkumab and golimumab (mid dose) and combination of guselkumab and golimumab (low dose).
The main study consists of Screening, Treatment, and Long-Term Extension (LTE) periods. The treatment period of the study will evaluate 48 weeks of therapy with guselkumab/golimumab co-formulation. All participants who are not responding based on defined measures at Week 24, including those assigned to the placebo Group, will have the opportunity for an increase in the level of treatment to mid- or high-dose combination.
