A Safety and Effectiveness Study of Golimumab in Japanese Patients With Moderately to Severely Active Ulcerative Colitis.

Participants will receive 200 mg golimumab at Week 0 and 100 mg golimumab at Week 2 as a subcutaneous (SC) (under the skin) injection in the induction phase. Participants who have a clinical response in the induction phase and are randomly allocated to golimumab in the maintenance phase will receive 100 mg SC every 4 weeks through Week 52. Participants who do not have a clinical response in the induction phase will receive 100 mg of golimumab SC at Week 4 and will continue with 100 mg of golimumab SC every 4 weeks through Week 52 only if a response is obtained by Week 8.

Participants who have a clinical response to golimumab in the induction phase and are randomly allocated to placebo in the maintenance phase will receive SC placebo every 4 weeks through Week 52. However, participants receiving placebo and who will lose clinical response any time during the study will be eligible to receive 100 mg golimumab SC every 4 weeks through Week 52.
