Study Arms:
- Adalimumab 0.4 mg/kg (Type: EXPERIMENTAL): In Period A participants received a single subcutaneous loading dose of adalimumab 0.4 mg/kg (up to a maximum of 20 mg) at Week 0 followed by every other week dosing beginning at Week 1. To maintain the blind, participants also received weekly dosing of methotrexate placebo tablets. Participants who were non-responders in Period A entered Period D directly and received open-label adalimumab at 0.8 mg/kg eow for up to 52 weeks. Participants who responded in Period A entered the Treatment Withdrawal Phase (Period B) for up to 36 weeks. Participants who experienced a loss of disease control in Period B entered the Re-treatment Phase (Period C) and received blinded adalimumab 0.4 mg/kg eow for 16 weeks. Participants who completed Period B with no loss of disease control entered Period D and were observed off study medication for up to 52 weeks. Participants who completed Period C entered Period D for an additional 52 weeks of treatment with blinded adalimumab 0.4 mg/kg eow.
- Adalimumab 0.8 mg/kg (Type: EXPERIMENTAL): In Period A participants received a single subcutaneous loading dose of adalimumab 0.8 mg/kg (up to a maximum of 40 mg) at Week 0 followed by every other week dosing beginning at Week 1. To maintain the blind, participants also received weekly dosing of methotrexate placebo tablets. Participants who were non-responders in Period A entered Period D directly and received open-label adalimumab at 0.8 mg/kg eow for up to 52 weeks. Participants who responded in Period A entered the Treatment Withdrawal Phase (Period B) for up to 36 weeks. Participants who experienced a loss of disease control in Period B entered the Re-treatment Phase (Period C) and received blinded adalimumab 0.8 mg/kg eow for 16 weeks. Participants who completed Period B with no loss of disease control entered Period D and were observed off study medication for up to 52 weeks. Participants who completed Period C entered Period D for an additional 52 weeks of treatment with blinded adalimumab 0.8 mg/kg eow.
- Methotrexate (Type: ACTIVE_COMPARATOR): Participants received 0.1 mg/kg methotrexate at Baseline (Week 0), and up to 0.4 mg/kg weekly (maximum dose of 25 mg/week) in Period A. Participants also received adalimumab placebo as a single subcutaneous loading dose at Week 0, followed by every other week (eow) dosing from Week 1. Participants who were non-responders in period A entered Period D directly and received open-label adalimumab at 0.8 mg/kg eow for up to 52 weeks. Participants who responded in Period A entered the Treatment Withdrawal Phase (Period B) for up to 36 weeks. Participants who experienced a loss of disease control in Period B entered the Re-treatment Phase (Period C) and received blinded adalimumab 0.8 mg/kg eow for 16 weeks. Participants who completed Period B with no loss of disease control entered Period D and were observed off study medication for up to 52 weeks. Participants who completed Period C entered Period D for an additional 52 weeks of treatment with blinded adalimumab 0.8 mg/kg eow.
