|E.2 Objective of the trial
|E.2.1||Main objective of the trial ||
|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.

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)

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

permitted for subjects who can not tolerate higher doses. In this circumstance, the
10 mg weekly dose will be permitted if there is verifiable documentation in the
medical record prior to entry into the study that the subject could not tolerate
higher doses. Use of parenteral methotrexate is acceptable as clinically indicated.
3) Age and Sex
a) Men and women, ages ≥ 18
Women of childbearing potential (WOCBP) must be using an adequate method of
contraception to avoid pregnancy throughout the study and for up to 10 weeks weeks (and for 14 weeks in the European countries in which the European SmPC for Orencia® IV is applicable) after the last dose of abatacept in such a manner that the risk of pregnancy is minimized.
4) Concomitant medication
Informed consent must be signed before making any changes in RA therapy, if those
are solely for the purpose of this study.
a) Drug stabilization requirements:
Oral corticosteriod treatment must have been reduced to the equivalent of ≤ 10 mg
prednisone daily for 28 days and stabilized for at least 25 out of 28 days prior to treatment (Day 1). No intra-articular or IM injections of corticosteriods are permitted
within 28 days prior to treatment (Day 1).
b) Washout requirements:
Subjects receiving methotrexate monotherapy will not require a washout. Subjects
receiving combination RA therapy should discontinue their DMARDs (other than methotrexate) at least 28 days prior to treatment (Day 1).
Required washout periods (prior to Day 1):
At least 4 weeks for

− mycophenylate mofetil (CellCept®)
− Immunoadsorption columns
At least 8 weeks for
− Leflunomide (or perform active wash-out with cholestyramine according to
the manufacturer’s recommendations).

washout period (see Inclusion Criteria #4).

i) 10 or more swollen joints (66 joint count) and
ii) 12 or more tender joints (68 joint count) and
iii) C reactive protein (hsCRP) ≥ 0.8 mg/dL (result used from screening visit).
b) For subjects receiving methotrexate plus other DMARDs (washout):
At screening visit, subjects must have the following disease activity:
i) 6 or more swollen joints (66 joint count) and
ii) 8 or more tender joints (68 joint count) and
