Title: A Phase III Multi-centre, Open-label, follow-on Study to CDP870-027, to Assess the Efficacy and Safety of Lyophilized CDP870 an Engineered Human Anti-TNF PEG Conjugate, as Additional Medication to Methotrexate, in the Treatment of Signs and Symptoms and Preventing Structural Damage in Patients With Active Rheumatoid Arthritis
Brief Summary: An open ended study in which patients who completed the double-blind study CDP870-027 \[NCT00152386\] are given Certolizumab Pegol (CZP) and assessed for signs and symptoms of Rheumatoid Arthritis (RA).


Options:
A: Inclusion Criteria:

* had received methotrexate
* on a stable dose of folic acid

Exclusion Criteria:

* contraindication for methotrexate or anti-TNF
B: Inclusion Criteria:

* Patients with established adult rheumatoid arthritis currently on Methotrexate for at least 3 months

Exclusion Criteria:

* All concomitant diseases or pathological conditions that could interfere and impact the assessment of the study treatment
* Previous clinical trials participation and previous biological therapy that could interfere with the results of the present clinical trial
C: Inclusion Criteria:

Patients must have either failed to achieve American College of Rheumatology 20 % Response Criteria (ACR20) at Weeks 12 and 14 in C87027 \[NCT00152386\], or must have completed the entire Week 52 assessment of C87027 \[NCT00152386\] trial.

Exclusion Criteria:

* A diagnosis of any other inflammatory Arthritis (e.g. Psoriatic Arthritis or Ankylosing Spondylitis)
* A secondary, non-inflammatory type of Arthritis (e.g. Osteoarthritis or Fibromyalgia) that in the Investigator's opinion is symptomatic enough to interfere with evaluation of the effect of CDP870 on the patient's primary diagnosis of Rheumatoid Arthritis
* Any concomitant biological therapy
* Any experimental therapy, within or outside a clinical trial
D: Inclusion Criteria:

* Male and female, aged at least 18 years old at the Screening visit.
* A clear chest X-ray within 3 months prior to Baseline visit.
* A diagnosis of adult-onset RA (of at least six months duration but not longer than 15 years prior to Screening) as defined by the 1987 American College of Rheumatology classification criteria.
* Active RA disease at Screening and Baseline as defined by:

  * ≥9 tender joints.
  * ≥9 swollen joints. and fulfilling 1 of the following 2 criteria:
  * ≥30 mm/hour ESR (Westergren), or
  * CRP \>15 mg/L.
* Must have received a stable dose of MTX with or without folic acid for at least 3 months prior to Baseline visit. The minimum dose is 10 mg MTX weekly.
* Patient must be willing to attend for a Week 52 X-ray of the hands and feet even if they are no longer receiving study treatment but have not withdrawn their informed consent.

Exclusion Criteria:

* A diagnosis of any other inflammatory arthritis e.g., psoriatic arthritis or ankylosing spondylitis.
* A secondary, non-inflammatory type of arthritis (e.g. OA or fibromyalgia) that in the Investigator's opinion is symptomatic enough to interfere with evaluation of the effect of CDP870 on the patient's primary diagnosis of RA.
* A history of an infected joint prosthesis at any time with prosthesis still in situ.
* Does not meet exclusionary concomitant medication criteria.
* A history of a lymphoproliferative disorder including lymphoma or signs and symptoms suggestive of lymphoproliferative disease at any time.
* Patients at a high risk of infection in the Investigator's opinion (e.g. leg ulcers, indwelling urinary catheter and persistent or recurrent chest infections).
