Title: A Phase III Multicentre, Double Blind, Placebo-controlled, Parallel Group 52-week Study to Assess the Efficacy and Safety of 2 Dose Regimens of Lyophilised CDP870 as Additional Medication to Methotrexate in the Treatment of Signs and Symptoms and Preventing Structural Damage in Patients With Active Rheumatoid Arthritis Who Have an Incomplete Response to Methotrexate
Brief Summary: Patients will be assigned to one of three treatment groups. Study medication is administered over a 52 week study duration.


Options:
A: Inclusion Criteria:

* Subjects must have a diagnosis of adult-onset RA of at least 6 months but not longer than 15 years in duration as defined by the 1987 American College of Rheumatology classification criteria.
* Subjects must have active RA disease as defined by:

  * At least 9 tender joints and 9 swollen joints
  * ESR of 30 mm/hour or CRP of 1.5 mg/dL
* Subjects must have received treatment with MTX for at least 6 months prior to the start of study drug administration. The dose of MTX must have remain fixed for at least 2 months prior to the study and the dose of MTX should be within 6 to 8 mg/week.

Exclusion Criteria:

* Patients who have a diagnosis of any other inflammatory arthritis
* Patients who have a secondary, non-inflammatory type of arthritis (eg, osteoarthritis, fibromyalgia)
* Patients who currently have, or who have a history of, a demyelinating or convulsive disease of the central nervous system (eg, multiple sclerosis, epilepsy)
* Patients who have NYHA (New York Heart Association) Class III or IV congestive heart failure
* Patients who currently have, or who have a history of, tuberculosis
* Patients who have a high risk of infection (with a current infectious disease, a chronic infectious disease, a history of serious infectious disease)
* Patients who currently have, or who have a history of, malignancy
* Female patients who are breastfeeding or pregnant, who are of childbearing potential
* Patients who previously received treatment with 2 or more anti-TNFα drugs or who previously failed to respond to treatment with 1 or more aint-TNFα drugs.
B: Inclusion Criteria:

Patients must have either failed to achieve an American College of Rheumatology 20 % (ACR20) response at Weeks 12 and 14 in C87050 \[NCT00160602\], or must have completed the entire Week 24 assessment of C87050 \[NCT00160602\] 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 (RA)
* Any concomitant biological therapy
* Any experimental therapy, within or outside a clinical
C: Inclusion Criteria:

* Adult patient with established moderate to severe rheumatoid arthritis

Exclusion Criteria:

* All concomitant diseases or pathological conditions that could interfere and impact the assessment of the study treatment
* Previous clinical trials and previous biological therapy that could interfere with the results in the present clinical trials
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).
