The purpose of this study is to evaluate the efficacy and safety of guselkumab in participants with moderately to severely active ulcerative colitis (UC).
- Conditions
- Ulcerative Colitis
- Being tested
- Placebo, Guselkumab
- Medical subject headings
- Colitis, Ulcerative
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PlaceboDrug
Participants will receive matching placebo IV or SC.
GuselkumabDrug
Participants will receive guselkumab IV or SC.
| Study group | Role | What they receive |
|---|---|---|
| Induction Study 1: Guselkumab Dose 1 | Experimental | Participants will receive guselkumab dose 1 intravenously (IV) in Induction Study 1. Subsequent study treatment will be determined by the participant's clinical response status at Week 12. Receives: Drug: Guselkumab |
| Induction Study 1: Guselkumab Dose 2 | Experimental | Participants will receive guselkumab dose 2 IV in Induction Study 1. Subsequent study treatment will be determined by the participant's clinical response status at Week 12. Receives: Drug: Guselkumab |
| Induction Study 1: Placebo IV | Placebo comparator | Participants will receive matching placebo IV in Induction Study 1.

What is being measured
The primary outcome is the main question the study is designed to answer.
Induction Study 1: Percentage of Participants With Clinical Response at Week I-12
Clinical response was defined as a decrease from induction baseline in the modified Mayo score by greater than or equal to (>=) 30 percent (%) and >=2 points, with either a >=1 point decrease from baseline (Week 0 of IS-1) in the rectal bleeding subscore or a rectal bleeding subscore of 0 or 1. The modified Mayo scores consisted of 3 subscores: stool frequency, rectal bleeding and endoscopic subscore as determined during central review, each subscore graded from 0 (normal) to 3 (severe) with higher scores indicating more severe disease. These individual subscores were summed up to give a total modified Mayo score range of 0 (normal) to 9 (severe disease), where higher scores indicated more severe disease activity. This outcome measure was planned to be analyzed for specified arms only.
Measured: At Week I-12
Induction Study 2: Percentage of Participants With Clinical Remission at Week I-12
Clinical remission was based on the modified Mayo score. Clinical remission was defined as Mayo stool frequency subscore of 0 or 1 and not increased from baseline (Week 0 of IS-2), a Mayo rectal bleeding subscore of 0, and Mayo endoscopic subscore of 0 or 1 with no friability. The modified Mayo scores consisted of 3 subscores: stool frequency, rectal bleeding and endoscopic subscore as determined during central review, each subscore graded from 0 (normal) to 3 (severe) with higher scores indicating more severe disease. These individual subscores were summed up to give a total modified Mayo score range of 0 (normal) to 9 (severe disease), where higher scores indicated more severe disease activity. This outcome measure was planned to be analyzed for specified arms only.
Measured: At Week I-12
Maintenance Study: Percentage of Participants With Clinical Remission at Week M-44
Clinical remission was based on the modified Mayo score. Clinical remission was defined as Mayo stool frequency subscore of 0 or 1 and not increased from baseline (Week 0 of IS-1 and IS-2), a Mayo rectal bleeding subscore of 0, and Mayo endoscopic subscore of 0 or 1 with no friability. The modified Mayo scores consisted of 3 subscores: stool frequency, rectal bleeding and endoscopic subscore as determined during central review, each subscore graded from 0 (normal) to 3 (severe) with higher scores indicating more severe disease. These individual subscores were summed up to give a total modified Mayo score range of 0 (normal) to 9 (severe disease), where higher scores indicated more severe disease activity. This outcome measure was planned to be analyzed for randomized arms only.
Measured: At Week M-44

Primary outcome
Induction Study 1: Percentage of Participants With Clinical Response at Week I-12
Time frame: At Week I-12
Clinical response was defined as a decrease from induction baseline in the modified Mayo score by greater than or equal to (>=) 30 percent (%) and >=2 points, with either a >=1 point decrease from baseline (Week 0 of IS-1) in the rectal bleeding subscore or a rectal bleeding subscore of 0 or 1. The modified Mayo scores consisted of 3 subscores: stool frequency, rectal bleeding and endoscopic subscore as determined during central review, each subscore graded from 0 (normal) to 3 (severe) with higher scores indicating more severe disease. These individual subscores were summed up to give a total modified Mayo score range of 0 (normal) to 9 (severe disease), where higher scores indicated more severe disease activity. This outcome measure was planned to be analyzed for specified arms only.
Induction Study 2: Percentage of Participants With Clinical Remission at Week I-12
Time frame: At Week I-12
Clinical remission was based on the modified Mayo score. Clinical remission was defined as Mayo stool frequency subscore of 0 or 1 and not increased from baseline (Week 0 of IS-2), a Mayo rectal bleeding subscore of 0, and Mayo endoscopic subscore of 0 or 1 with no friability. The modified Mayo scores consisted of 3 subscores: stool frequency, rectal bleeding and endoscopic subscore as determined during central review, each subscore graded from 0 (normal) to 3 (severe) with higher scores indicating more severe disease. These individual subscores were summed up to give a total modified Mayo score range of 0 (normal) to 9 (severe disease), where higher scores indicated more severe disease activity. This outcome measure was planned to be analyzed for specified arms only.
Maintenance Study: Percentage of Participants With Clinical Remission at Week M-44
Time frame: At Week M-44
Clinical remission was based on the modified Mayo score. Clinical remission was defined as Mayo stool frequency subscore of 0 or 1 and not increased from baseline (Week 0 of IS-1 and IS-2), a Mayo rectal bleeding subscore of 0, and Mayo endoscopic subscore of 0 or 1 with no friability. The modified Mayo scores consisted of 3 subscores: stool frequency, rectal bleeding and endoscopic subscore as determined during central review, each subscore graded from 0 (normal) to 3 (severe) with higher scores indicating more severe disease. These individual subscores were summed up to give a total modified Mayo score range of 0 (normal) to 9 (severe disease), where higher scores indicated more severe disease activity. This outcome measure was planned to be analyzed for randomized arms only.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
