Title: A Multi-center, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of Certolizumab Pegol in Combination With Methotrexate for Inducing and Sustaining Clinical Response in the Treatment of DMARD-Naïve Adults With Early Active Rheumatoid Arthritis
Brief Summary: This study is intended to evaluate the efficacy and safety of Certolizumab Pegol (CZP) in combination with Methotrexate (MTX) for sustaining clinical response achieved in study RA0055 Period 1 \[NCT01519791\]. Subjects entering this study RA0055 Period 2 achieved sustained Low Disease Activity at Week 52 in study RA0055 Period 1.


Options:
A: Inclusion Criteria:

1. Subject has a minimum 1 year history/diagnosis of rheumatoid arthritis based on the 1987 American College of Rheumatology (ACR) Revised criteria for RA.
2. Subject must have active rheumatoid arthritis despite methotrexate (MTX) therapy of ≥10 mg/wk for at least 12 weeks. The MTX dose must be stable for at least 4 weeks immediately prior to screening.

Exclusion Criteria:

1. Subjects who used any of the following systemic treatments during the washout periods given below:

   1. Oral corticosteroid dose of prednisone \>7.5 mg/day (or equivalent) or a change in dose within 28 days of baseline.
   2. Treatment with more than 1 NSAID within 14 days at baseline.
   3. Methotrexate dose greater than 25 mg/week, or change in the dose of methotrexate within 28 days of baseline.
   4. Subjects will be allowed to continue the following non biologic DMARDs: sulfasalazine, hydroxychloroquine, and leflumomide. All other non-biologic DMARDs (including but not limited to gold, penicillamine, azathioprine, cyclophospamide), and biologic DMARDs must have been discontinued at least 2 months prior to Week 1.
   5. Any biologic B cell depleting agent (eg, rituximab) within 2 years of Week 1.
2. Receipt of any live (attenuated) vaccine within 4 weeks prior to baseline.
3. Receipt of any live (attenuated) vaccine within 4 weeks prior to baseline.
B: Inclusion Criteria:

* Patients aged 18 or more, diagnosed with RA according to the 1987 ACR classification criteria;
* RA treated with subcutaneous TNF-blockers (étanercept or adalimumab) at stable and standard dosage for 1 year or more, as monotherapy or associated with stable conventional DMARD;
* RA in clinical remission, defined as a stable DAS28 ≤ 2.6 for 6 months or more, without any structural damage progression on X-rays (local reading by the treating rheumatologist);

Exclusion Criteria:

* Treatment with steroids;
* progressing disease on X-rays during the year preceding the trial;
* surgery planed in the 18 coming months;
* pregnancy;
* on-going neoplastic disease;
* other auto-immune disorders different from RA;
* inability to speak or understand French;
* absence of signed informed consent;
* absence of medical insurance coverage.
C: Inclusion Criteria:

- Those subjects in previous study RA0055 Period 1 who are in sustained LDA (defined as DAS28\[ESR\] ≤ 3.2 at Weeks 40 and 52) at Week 52 in previous study RA0055 Period 1

Exclusion Criteria:

- Those subjects in previous study RA0055 Period 1 who are NOT in sustained LDA (defined as DAS28\[ESR\] ≤ 3.2 at Weeks 40 and 52) at Week 52 in previous study RA0055 Period 1
D: Inclusion Criteria:

* Diagnosis of rheumatoid arthritis.
* Currently receiving an optimal dose of oral Methotrexate (MTX)(at least 15 mg/week but no more than 25 mg/week) for the treatment of rheumatoid arthritis.
* Active rheumatoid arthritis at the time of screening.

Exclusion Criteria:

* Previous or current treatment with etanercept, other tumor necrosis factor-alpha (TNF) inhibitors, or other biologic agents.
* Concurrent treatment with any disease-modifying anti-rheumatoid drugs (DMARD), other than MTX within 28 days before baseline.
* Concurrent treatment with more than 1 non-steroid anti-inflammatory drug (NSAID) at baseline.
