- Healthy Volunteers: f

Study Arms:
- Ustekinumab (Stelara) (Type: ACTIVE_COMPARATOR): Ustekinumab (Stelara) subcutaneous injection 45mg (if person's weight is 100kg or less) or 90mg (if person's weight is greater than 100kg) at day 0 and week 4 followed by every 12-week dosing thereafter. Patient will receive total of 52 weeks of ustekinumab (12 weeks during RCT phase, 40 weeks post RCT phase). The end of study is at Week 52 for this arm.
- Placebo (Type: PLACEBO_COMPARATOR): Placebo subcutaneous injection will be given according to the same dose and schedule as the active comparator until week 12 (end of RCT phase). At week 12, ustekinumab will be administered according according to the same injection schedule as the active comparator arm for 52 weeks. Patient will receive total of 52 weeks of ustekinumab (0 weeks during RCT phase, 52 weeks post RCT phase). The end of study is at Week 64 for this arm.
