the diagnosis of rheumatoid arthritis.
4) Subjects must have a diagnosis of RA less than or equal to 2 years.
5) Subjects must have high disease activity as defined by a tender joint count of 10,
swollen joint count of 12, and a CRP of .8 dg/L or 8.0 mg/L.
6) Subjects that are RF or anti-CCP positive.
7) Subjects must have evidence of erosion of the hands, wrists or feet on the screening radiograph. (To be read centrally)

25 IU/L or equivalent units of HCG) within 48 hours prior to the start of study
medication.
Male subjects must be using an adequate method of contraception throughout the study including up to 10 weeks after the last infusion of abatacept so that the risk of pregnancy to their partner is minimized.

rheumatoid nodules.
6) Subjects with current symptoms of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, pulmonary, cardiac, neurological, or cerebral disease, or other medical conditions that, in the opinion of the investigator, might place the subject at unacceptable risk for participation in this study.
7) Female subjects, who have not had age and/or risk factor appropriate breast cancer screening or who have had a breast cancer screening study that is suspicious for malignancy, and in whom the possibility of malignancy cannot be reasonably excluded following additional clinical, laboratory or other diagnostic evaluations (Please refer to Section 7.3.2).
8) Subjects with a history of cancer within the last five years (other than non-melanoma skin cell cancers cured by local resection). Existing non-melanoma skin cell cancers must be removed prior to dosing.

pyelonephritis) unless treated and completely resolved with antibiotics.
11) Subjects with severe chronic or recurrent bacterial infections (such as recurrent
pneumonia, chronic bronchiectasis).
12) Subjects with active tuberculosis (TB) requiring treatment within the previous
3 years. A PPD response that is equal to or greater than 10 mm should be considered a positive test, although a lower threshold (5 mm) may be applied as determined by the clinical circumstance and investigator according to published guidelines and/or local standards endorsed by the medical society. (Section 7.3.2)
13) Subjects with herpes zoster that resolved less than 2 months prior to enrollment.
14) Subjects with evidence (as assessed by the investigator) of active or latent bacterial or viral infections at the time of potential enrollment, including subjects with evidence of Human Immunodeficiency Virus (HIV) infection.

- Platelets < 100,000/mm3 (100 x 109/L).
- Serum creatinine > 2 times upper limit of normal.
- Serum ALT or AST > 2 times upper limit of normal.
- Any other laboratory test results that, in the opinion of the investigator, might place
the subject at unacceptable risk for participation in this study.
18) Subjects with a history of intolerance to methotrexate.
19) Subjects who have at any time received treatment with CTLA4Ig, BMS-188667
(abatacept).
