Brief summary
This study is conducted to evaluate the short (12 Weeks) and long term (104 Weeks) efficacy of Certolizumab Pegol compared with Adalimumab both in combination with Methotrexate (MTX) in the treatment of moderate to severe Rheumatoid Arthritis (RA) that is not responding adequately to MTX.

| ADA+MTX (FAS) | Percentage of Subjects With a Disease Activity Score 28 [Erythrocyte Sedimentation Rate] (DAS28 [ESR]) ≤ 3.2 at Week 104, in Subjects Responding at Both Week 6 and Week 12 | 46.6 Percentage of subjects |
Percentage of Week 12 Responders Who Had a Disease Activity Score 28 [Erythrocyte Sedimentation Rate] (DAS28 [ESR]) ≤ 3.2 at Week 104
DAS28 \[ESR\] was calculated using the Tender Joint Count (TJC), Swollen Joint Count (SJC), Erythrocyte Sedimentation Rate (ESR in mm/hour), and the Patient's Global Assessment of Disease Activity - Visual Analog Scale (PtGADA-VAS in mm) using the following formula: 0.56 x √ (TJC) + 0.28 x √ (SJC) + 0.70 x lognat (ESR) + 0.014 x Patient Global Assessment of Arthritis, where 28 joints were examined and a lower score indicates less disease activity. The definition of Week 12 responders was DAS28\[ESR\] Low Disease Activity (LDA) (ie ≤ 3.2) or an improvement of ≥ 1.2 in DAS28\[ESR\] relative to Baseline.
Time frame: Week 104
Population: Week 12 Responders were defined as those with DAS28(ESR) LDA (defined as DAS28\[ESR\] ≤3.2) or a DAS28(ESR) CFB reduction of ≥1.2 at Week 12.
