Title: Phase IV Study of Early RA: a Randomized Magnetic Resonance Imaging Study Comparing the Effects of Methotrexate Alone or in Combination With Infliximab or Intravenous Pulse Methylprednisolone
Brief Summary: The purpose of the study is to compare the effects of methotrexate (MTX) alone or in combination with intravenous (IV) methylprednisolone (MP) or infliximab (IFX) on MRI-detected synovitis, bone edema and erosive changes in early rheumatoid arthritis (RA) patients.

Major exclusion criteria:

* Patients who were Steinbrocker Class IV.
* Patients who received leflunomide within 12 weeks, DMARDs other than MTX within 8 weeks , or tacrolimus within 4 weeks before the 1st TCZ infusion.

B: Inclusion Criteria:

* Patients must be at least 18 years old at the screening visit.
* Patients must have a diagnosis of adult-onset RA of at least six months duration but not longer than fifteen years as defined by the 1987 American College of Rheumatology classification criteria.
* Patients must have active RA disease as defined by:

  * 9 tender joints at Screening and Baseline.
  * 9 swollen joints at Screening and Baseline. and fulfilling 1 of the following 2 criteria during the screening period:

The dose of MTX and route of administration must have been stable for at least 2 months prior to the baseline visit. The minimum stable dose of MTX allowed is 10 mg weekly.
* Patients must be willing to complete an X-ray of the hands and feet 24 weeks after randomization even if they are no longer receiving study treatment in the present study, provided they have not withdrawn their informed consent.

Exclusion Criteria:

* Patients with known human immunodeficiency virus (HIV) infection.
* Patients with an active malignancy of any type or a history of malignancy (except basal cell carcinoma of the skin that has been excised prior to study start).
* Patients with a current or recent history, as determined by the Investigator, of severe, progressive, and/or uncontrolled renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, cardiac, neurological, or cerebral disease which would interfere with the patient's participation in the trial.
