Title: A Phase IIIb, Multi-Center, Randomized, Withdrawal Study to Evaluate the Immunogenicity and Safety of Subcutaneous Administered Abatacept in Adults With Active Rheumatoid Arthritis
Brief Summary: The purpose of the study is to determine whether subcutaneous abatacept administered to patients with rheumatoid arthritis is associated with increased immunogenicity or increased safety events upon withdrawal and reintroduction.


Options:
A: Inclusion Criteria:

* Clinical diagnosis of Rheumatoid Arthritis
* Disease Activity Score (DAS)28-C-Reactive Protein (CRP) score ≥ 3.2 and ≤5.1
* On background methotrexate at least 3 months (≥10mg weekly)
* Must be able to self injection or allow a care giver to do it for them
* Discontinue all Biologics and Disease-Modifying Anti-rheumatic Drugs (DMARDs) except for methotrexate

Exclusion Criteria:

* Participants who had prior exposure to abatacept or CTLA-4 Ig
* Received treatment with rituximab.
* Participants who have received treatment with leflunomide within 1 year of screening
* Participants who have received treatment with immunoadsorption columns (such as Prosorba columns), mycophenolate mofetil (Cellcept®), cyclosporine A or other calcineurin inhibitors, or D-Penicillamine.
B: Inclusion Criteria:

* Diagnosis of RA according to the 1987 revised ACR Criteria for the Classification of RA for at least 6 months prior to screening
* Positive for rheumatoid factor or anti-cyclic citrullinated peptide (CCP) antibody, or both
* Active disease, defined as: CRP \>= 1.0 mg/dL; swollen joint count \>= 6 (66 joint count); tender joint count \>= 6 (68 joint count)
* Previous inadequate clinical response to at least one disease-modifying anti-rheumatic drug (DMARD) consisting of either methotrexate (MTX) or leflunomide (LFU)
* For patients currently receiving corticosteroids: Treatment at a stable dose during last 4 weeks prior to screening
* For patients currently receiving non-steroidal anti-inflammatory drugs (NSAIDs): Treatment at a stable dose during last 4 weeks prior to screening
* For patients currently receiving sulfasalazine or anti-malarials: Treatment initiated and continued for at least the last 6 months prior to screening and on a stable dose
* For patients of reproductive potential (males and females): Willing to use a highly effective birth control method for the duration of the study according to local guidelines

Exclusion Criteria:

* Pregnant, planning to become pregnant during the study, or breastfeeding
* Clinically significant abnormal laboratory values or abnormal ECG or vital signs
* History of anaphylactic reactions
* Rheumatic autoimmune disease other than RA, or significant systemic involvement secondary to RA (including but not limited to vasculitis, pulmonary fibrosis, or Felty's syndrome), however patients with secondary Sjogren's syndrome are eligible for the study
* History of or current inflammatory joint disease other than RA (e.g., gout, reactive arthritis, psoriatic arthritis, seronegative spondyloarthritis, Lyme disease) or other systemic autoimmune disorder (e.g., systemic lupus erythematosus, inflammatory bowel disease, scleroderma, inflammatory myopathy, mixed connective tissue disease, or other overlap syndrome)
* Current or recent (within 4 weeks prior to screening) infection, including signs, symptoms or serology of any infection, including HIV, hepatitis B or C, tuberculosis
* Administration of a live, attenuated vaccine within 1 month before dosing or anticipation that such a live attenuated vaccine will be required during the study
* Previous treatment with anti-TNF biologics or other biologic agents, including anti-CD20-directed therapy (e.g. rituximab), anti-IL6-directed therapy (e.g. tocilizumab), or T cell-directed therapy (e.g. abatacept)
C: Inclusion Criteria:

* Subject was age 18 or older and in good health (Investigator discretion) with a recent stable medical history.
* Diagnosis of rheumatoid arthritis (RA) as defined by the 1987-revised American College of Rheumatology (ACR) criteria, with a disease duration less than 3 years, at least 8 swollen joints out of the 66 joints assessed, at least 10 tender joints out of the 68 joints assessed, at least 1 joint erosion or rheumatoid factor (RF) positivity, erythrocyte sedimentation rate (ESR) \>= 28 mm/1h or C-reactive protein (CRP) \>= 1.5 mg/dl

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
D: Inclusion:

- Generally healthy of at least 18 years of age with active rheumatoid arthritis.

Exclusion:

- A history or presence of clinically important medical disease.
