Title: A Phase IIIb Open-label run-in Double-blind, Placebo Controlled, Randomized Study to Evaluate the Safety/Efficacy of Certolizumab Pegol Administered Concomitantly With Stable-dose Methotrexate in Patients With Active Rheumatoid Arthritis.
Brief Summary: During the run-in period, CZP will be administered at 400 mg (2 injections) at Wks 0, 2, and 4 and 200 mg with placebo (1 injection placebo, 1 injection CZP) at Wks 6, 8, 10, 12, 14 and 16. At Wk 18 patients will be grouped as responders or non-responders based on results of the ACR20 at Week 16.


Options:
A: Inclusion Criteria

1. Male and female subjects aged ≥18 years at the time of signing the Informed Consent Form.
2. Patients with a diagnosis of rheumatoid arthritis as per the ACR/EULAR 2010 classification criteria (Appendix 7) confirmed at least 24 weeks prior to the screening visit.
3. Patients who have failed conventional DMARD therapy as per NICE/BSR Guidelines (49) i.e. failure of at least 2 DMARDS including MTX.
4. Patients with persistent RA disease activity despite having been treated with a current initial TNFi agent for at least 12 weeks. Active RA defined as\*:

   1. Primary non-response: failing to improve DAS28 by \> 1.2 (Appendix 6) or failing to achieve DAS28 ≤ 3.2 within the first 12 to 24 weeks of starting the initial TNFi.

      • This may include patients that have shown a reduction in DAS28 of \> 1.2 but still demonstrate unacceptably high disease activity in the physician's judgement with evidence of an overall DAS28 of ≥ 3.2 OR
   2. Secondary non-response: defined as inefficacy to first TNFi (having demonstrated prior satisfactory response) as per clinician judgement; with intolerance not the reason for cessation of first TNFi.
5. MTX dose stable for 4 weeks prior to the screening visit and to be continued for the duration of the study.
6. Patients on NSAIDs and / or corticosteroids (oral prednisolone not exceeding 10mg daily) who have been on an unchanged regimen for at least 4 weeks prior to the screening visit and are expected to remain on a stable dose until the baseline assessments have been completed.
