for malignancy & in whom possibility of malignancy cannot be reasonably
excluded following additional clinical, laboratory or other diagnostic evaluations
(Protocol Section 6.3.6)

screening test indicative of latent TB will not be eligible for the study unless

drug & they have a negative chest X-ray at enrollment. Such subjects should

Primary Outcome(s)

Primary end point(s): The primary analysis will assess the proportion of subjects meeting the ACR criteria of 20% improvement (ACR 20) after 6 months (Day 169). The ACR 50, ACR 70 and HAQ will also be assessed.

Main Objective: The primary objective for this study is to demonstrate that subcutaneous (SC)
injections of abatacept are non-inferior to intravenous (IV) infusions of abatacept in ACR 20 responses after 6 months of treatment in subjects who have active RA, are receiving methotrexate and experiencing an inadequate response to methotrexate.

Secondary Objective: 1) Assess the proportion of subjects with ACR 50 response at month 6 (Day 169).
2) Assess the proportion of subjects with ACR 70 response at month 6 (Day 169).
3) Assess the pharmacokinetics of SC injections of abatacept.
4) Assess the immunogenicity of abatacept.
5) Assess the change in physical function as measured by the HAQ disability index at
Month 6 (Day 169).
6) Assess the proportion of subjects with a HAQ response as measured by a reduction of at least 0.3 unit from baseline in the HAQ disability index at Month 6 (Day 169)
7) Assess the safety and tolerability of SC injections of abatacept.

Subjects receiving SC injections of abatacept will be assessed relative to subjects
receiving IV infusions of abatacept.
