Brief summary: Single-Open Label Study to Assess Changes in the Immune Profile in Response to Treatment with Intravenous Abatacept Adults with Rheumatoid Arthritis who are Naive to Biologic Disease-Modifying Antirheumatic Drugs

Detailed description: The immune system of patients with Rheumatoid Arthritis (RA) is different from that of people who do not have RA. The purpose of this study is to examine participants' immune cells and proteins before initiation of study medication and after initiation of treatment with an approved therapy for RA, abatacept that will be given in combination with Methotrexate and/or anti-rheumatic drugs (DMARDS) that are approved for the treatment of RA. This study will assess whether participants have clinically responded to these medications. This assessment will also include a study of whether characteristics of participants' immune systems were changed by therapy with the study drug, abatacept.

  3. pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within
  4. 24 hours prior to the start of study drug.
  5. Women must not be breastfeeding and must agree not to breastfeed during the study and for 100 days thereafter
  6. WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug plus 5 half-lives of study drug (70 days) plus 30 days (duration of ovulatory cycle) for a total of 100 days post-treatment completion.

  3. Intrauterine hormone-releasing system (IUS)
  4. Complete abstinence- Complete abstinence is defined as the complete avoidance of heterosexual intercourse

     1. complete abstinence is an acceptable form of contraception for all study drugs and must be used throughout the duration of the study treatment (plus 5 half-lives of the investigational drug plus 30 days).
     2. It is not necessary to use any other method of contraception when complete abstinence is elected.
     3. Subjects who choose complete abstinence must continue to have pregnancy tests
     4. Acceptable alternate methods of highly effective contraception must be discussed in the event that the subject chooses to forego complete abstinence.
     5. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject.
* Unacceptable methods of contraception

  1. Periodic abstinence (calendar, symptothermal, post-ovulation methods)
