Title: A Phase IIIB, Multi-Center, Randomized, Double-Blind, Placebo-Controlled Comparative Study of Abatacept or Infliximab in Combination With Methotrexate in Controlling Disease Activity in Subjects With Rheumatoid Arthritis Having an Inadequate Clinical Response to Methotrexate
Brief Summary: The purpose of this clinical research study is to learn if Abatacept or Infliximab in combination with Methotrexate demonstrate a greater reduction in disease activity over placebo.


Options:
A: Inclusion Criteria:

* Have a diagnosis of rheumatoid arthritis (RA) (according to the revised 1987 criteria of the ACR) for at least 3 months prior to screening
* Must have been treated with and tolerated methotrexate (MTX) at a dose of at least 15 mg/week for at least 3 months prior to screening, and have a MTX dose of \>=15 mg/week and \<=25 mg/week and stable for at least 4 weeks prior to screening
* Have active RA as defined by persistent disease activity with at least 4 swollen and 4 tender joints, at the time of screening and baseline, and at least 2 of the following 4 criteria: a)C-reactive protein (CRP) \>=1.5 mg/dL at screening or erythrocyte sedimentation rate (ESR) by Westergren method of \>= 28 mm in the first hour at screening or baseline, b)Morning stiffness of \>= 30 minutes at screening and baseline, c)Bone erosion by x-ray and/or magnetic resonance imaging (MRI) prior to first administration of study agent, d)Anti-cyclic citrullinated peptide (anti-CCP) antibody-positive or rheumatoid factor (RF) positive at screening
* If using oral corticosteroids, must be on a stable dose equivalent to \<= 10 mg of prednisone/day for at least 2 weeks prior to first administration of study agent
* Are considered eligible according to specified tuberculosis (TB) screening criteria

Exclusion Criteria:

* Have inflammatory diseases other than RA that might confound the evaluation of the benefit of golimumab therapy
* Have had treatment with disease-modifying anti-rheumatic drugs (DMARDs)/systemic immunosuppressives other than MTX, during the 4 weeks prior to the first administration of study agent
* Have had prior treatment with biologic anti-tumor necrosis factor (TNF) drugs (infliximab, etanercept, adalimumab)
* Have had history of, or ongoing, chronic or recurrent infectious disease.
* Have serious infection within 2 months prior to first administration of study agent
* Have a history of latent or active granulomatous infection, including TB, histoplasmosis, or coccidioidomycosis, prior to screening
B: 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).
C: Inclusion Criteria:

* Diagnosis of Rheumatoid Arthritis
* At least 3 months prior treatment with Methotrexate (MTX)
* At least 10 swollen joints and 12 tender joints and C-Reactive Protein of at least 1 mg/dl
* Washout required for other disease modifying anti-rheumatic drugs (DMARDS)

Exclusion Criteria:

* participants who have failed more than 3 DMARDs
* participants previously treated with an approved biologic drug
* History of cancer in the last 5 years
* Severe or recurrent bacterial infection
* Any previous or current medical conditions that are contraindications to the use of TNF blocking agents
* Women of Child Bearing Potential
D: * Rheumatoid Arthritis (RA) for greater than 1 year from the time of initial diagnosis of RA.
* Participants must have been taking methotrexate for at least 3 months with at least a weekly dose of 15 mg.
