Change From Baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) at Week 104From Baseline to Week 104HAQ-DI was derived based on the mean of individual scores in 8 categories of daily living actives (using 20 questions).

Change from Baseline was computed as the value at Week 104 minus the Baseline value. A negative value in Change from Baseline indicates an improvement.
Kaplan-Meier Estimates of Proportion of Subjects Who Discontinued After Response at Week 12From Week 12 up to Week 104Response at Week 12 means that a subject had either a Disease Activity Score 28 \[Erythrocyte Sedimentation Rate\] (DAS28 \[ESR\]) ≤ 3.2 at Week 12 or had a reduction of DAS28 \[ESR\] ≥ 1.2 from Baseline to Week 12.

CZP+MTX (RTG)
Subjects received loading doses of CZP 400mg (200mg/PFS, ie, 2 injections) at Baseline, and Weeks 2 and 4; and CZP 200mg at Weeks 6, 8, and 10. Week 12 Responders continued CZP 200mg at Week 12 and every 2 weeks thereafter through Week 102. Week 12 Non-Responders were switched to receive ADA 40mg at Week 12 and every 2 weeks through Week 22. At Week 24, Week 12 Non-Responders who did not have DAS28(ESR) LDA or a DAS28(ESR) change from Week 12 reduction of ≥1.2 discontinued ADA treatment and were withdrawn from the Treatment Period. All subjects received Methotrexate 15 to 25mg/week orally or subcutaneously from Baseline through Week 104. Regimens could have been changed at Week 52 only. Subjects who could not tolerate these doses could receive MTX at a minimum dose of 10mg/week orally or subcutaneously.
457
ADA+MTX (RTG)
Subjects received ADA 40mg (40mg/PFS, ie, 1 injection) at Baseline and then every 2 weeks through Week 10. In order to preserve the blind (ie, use of 2 injections) until Week 12, subjects received an injection of PBO in addition to ADA at Baseline, and Weeks 2 and 4. Week 12 Responders continued ADA 40mg at Week 12 and every 2 weeks thereafter through Week 102. Week 12 Non-Responders were switched to a loading dose of CZP 400mg at Weeks 12, 14, and 16 followed by CZP 200mg every 2 weeks through Week 22. At Week 24, Week 12 Non-Responders who did not have DAS28(ESR) LDA or a DAS28(ESR) change from Week 12 reduction of ≥1.2 discontinued CZP treatment and were withdrawn from the Treatment Period. All subjects received Methotrexate 15 to 25mg/week orally or subcutaneously from Baseline through Week 104. Regimens could have been changed at Week 52 only. Subjects who could not tolerate these doses could receive MTX at a minimum dose of 10mg/week orally or subcutaneously.
