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 |
|
E.2.2 | Secondary objectives of the trial |
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. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1)Signed Written Informed Consent a) Subject is willing to participate in the study and signed the informed consent. 2)Target Population a) Subjects must meet the criteria of the American Rheumatism Association (1987) for the diagnosis of rheumatoid arthritis and the American College of Rheumatology (1991) functional Classes I, II, or III. (Protocol App. 3 and 4). b)Subjects must have had rheumatoid arthritis for more than 1 year from the initial diagnosis. Not Applicable per Amendment 03. c) Subjects with stable renal, endocrine, hepatic, hematological, gastrointestinal, pulmonary, cardiac, neurological or cerebral disease(s) (eg, diabetes mellitus, congestive heart failure, chronic obstructive pulmonary disease) will be allowed to participate in this study. d) Subjects who are considered methotrexate inadequate responders by a treating physician or investigator. Subjects must have been taking methotrexate for at least 3 months at a minimal weekly dose of 15 mg, and at a stable dose for 28 days prior to randomization (Day 1). A methotrexate weekly dose as low as 10 mg is 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 more or equal then 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 after the last dose of abatacept in such a manner that the risk of pregnancy is minimized.
