Title: A Phase IIIB Multicenter, Randomized, Double-Blind, Placebo-controlled Study to Assess Short-term Changes in Synovitis and Structural Damage Outcomes in Subjects With Active Rheumatoid Arthritis and Inadequate Response to Methotrexate, Treated With Abatacept Versus Placebo on a Background Therapy With Methotrexate
Brief Summary: The only trial in participants who are methotrexate-inadequate responders and have active Rheumatoid Arthritis, in which gadolinium-enhanced Magnetic Resonance Imaging; Bone Mineral Density; and biochemical markers of bone, cartilage, and synovial tissue metabolism are used to evaluate early effects (4 months) of Abatacept on inflammation/structural damage. Study will provide valuable mechanism-of-action information on how Abatacept exerts its effects (including on bone) through new techniques.


Options:
A: Inclusion Criteria:

* Subject was age 18 or older and in good health (Investigator discretion) with a recent stable medical history.

Exclusion Criteria:

* Chronic arthritis diagnosed before the age of 16
* Preceding treatment with MTX, cyclophosphamide, cyclosporin, azathioprine or more than 2 other disease-modifying anti-rheumatic drugs (DMARDs)
* Subject previously received anti-tumor necrosis factor (TNF) therapy
* Permanently wheelchair-bound or bedridden patients
* Subject considered by the investigator, for any reason, to be an unsuitable candidate for the study
* Female subject who is pregnant or breast-feeding or considering becoming pregnant
B: Inclusion Criteria:

* Adults with moderate to severe rheumatoid arthritis on a stable dose of methotrexate who have inadequate response to Tumor Necrosis Factor (TNF) inhibitors.

Exclusion Criteria:

* Pregnancy, severe acute or chronic medical conditions, including serious infections or clinically significant laboratory abnormalities.
C: Inclusion Criteria:

* Adult patients, ≥18 years of age
* Active rheumatoid arthritis of \>6 months duration
* Received permitted DMARDs each at a stable dose for at least 7 weeks prior to baseline

Exclusion Criteria:

* Rheumatic autoimmune disease or inflammatory joint disease other than rheumatoid arthritis
* Major surgery within 8 weeks prior to screening or planned within 6 months following randomization
* Unsuccessful treatment with a biologic agent, including an anti-TNF agent
* Previous treatment with tocilizumab
D: Inclusion Criteria:

* Disease activity as defined by a Disease Activity Score 28-C-Reactive Protein (CRP) \>3.2 or \>6 swollen and ≥6 tender joints and CRP greater than the upper limit of normal
* At least 1 erosion in hands/wrists or positive anticyclic citrullinated peptides or rheumatoid factor
* Clinically detectable synovitis of at least 1 wrist/ankle at screening and baseline
* Participants must have been treated with methotrexate, on a weekly dose of at least 15 mg or a maximum tolerated dose (such as, 10 mg weekly) for at least 3 months before screening. Dose of methotrexate must be stable for at least 28 days prior to the first study dose (Day 1)
