Placebo
Adalimumab 80 mg/40 mg
Adalimumab 160 mg/80 mg
Participants received placebo subcutaneous injections every 2 weeks for 52 weeks. From Week 8, participants with an inadequate response could switch to rescue therapy, where they initially received adalimumab 160 mg, 80 mg 2 weeks later, and then 40 mg every other week. Participants who completed the 52-week double-blind period received open-label adalimumab 40 mg every other week, with the possibility to escalate to 80 mg every other week, until drug approval.
Participants received adalimumab 80 mg on Day 1, 40 mg at Week 2 and 40 mg every other week from Week 4 to Week 50, via subcutaneous injection. From Week 8, participants with an inadequate response could switch to rescue therapy, where they received adalimumab 40 mg every other week. Participants who completed the 52-week double-blind period received open-label adalimumab 40 mg every other week, with the possibility to escalate to 80 mg every other week, until drug approval.
