KHK4083 Cohort 1
Subjects received one 1.0 mg/kg IV infusion treatment of KHK4083 every two weeks from Week 0 to Week 10 of Induction Therapy. Subjects who chose to continue into extension therapy and were eligible received one IV infusion every 4 weeks (at the same dose as Induction Therapy) from Week 12 to Week 48.
KHK4083 Cohort 2
Subjects received one 3.0 mg/kg IV infusion treatment of KHK4083 every two weeks from Week 0 to Week 10 of Induction Therapy. Subjects who chose to continue into extension therapy and were eligible received one IV infusion every 4 weeks (at the same dose as Induction Therapy) from Week 12 to Week 48.
KHK4083 Cohort 3
Subjects received one 10.0 mg/kg IV infusion treatment of KHK4083 every two weeks from Week 0 to Week 10 of Induction Therapy. Subjects who chose to continue into extension therapy and were eligible received one IV infusion every 4 weeks (at the same dose as Induction Therapy) from Week 12 to Week 48.
KHK4083 Cohort 4
Subjects received one maximum tolerated dose (10.0 mg/kg) IV infusion treatment of KHK4083 every two weeks from Week 0 to Week 10 of Induction Therapy. Subjects who chose to continue into extension therapy and were eligible received one IV infusion every 4 weeks (at the same dose as Induction Therapy) from Week 12 to Week 48.
Placebo
Subjects received one IV infusion treatment of Placebo every two weeks from Week 0 to Week 10 of Induction Therapy. Subjects who chose to continue into extension therapy and were eligible received one IV infusion every 4 weeks (at the same dose as Induction Therapy) from Week 12 to Week 48. Subjects who participated in Open-Label Therapy received KHK4083 instead of placebo.

Placebo
Subjects received placebo IV infusion treatments from Baseline to Week 12. Subjects who completed double-blind Induction Therapy (i.e., at least five of six treatments) were eligible to enter OLE Therapy and receive 10 treatments of open-label KHK4083 (at the same dose administered to that subject during Induction Therapy) as maintenance therapy. Each subject was to receive one IV infusion every 4 weeks from Week 12 to Week 48.

Timeframe: 12 weeks

Population: Full analysis set - All randomized subjects who received at least one full dose of investigational product and had a Baseline and at least one post-treatment primary efficacy variable.

The Mayo Clinic Score is comprised of 4 parts: stool frequency, rectal bleeding, endoscopic findings and physician's global assessment, each scored from 0-3. The total score ranges from 0-12 with higher scores indicating increased severity of disease. Improvement will be based on a reduction in the total Mayo Clinic score.

Population: The overall number of participants is the number in the full analysis set. The number of patients analyzed is the number of patients who had values at the noted visits. There were no subjects in the 10.0 mg/kg KHK4083 group in the LTE Therapy Period. There were no subjects in the 1.0 mg/kg KHK4083 group in the OLE Therapy Period.

The Mayo Clinic Score is comprised of 4 parts: stool frequency, rectal bleeding, endoscopic findings and physician's global assessment, each scored from 0-3. The total score ranges from 0-12 with higher scores indicating increased severity of disease. Improvement was based on a reduction (mean change from Baseline \[Week 0\] to Week 52) in the total Mayo Clinic score.
