A Phase 2a, randomized, double-blind, placebo-controlled, multicenter study to evaluate the efficacy, safety, and tolerability of BG00012 when given with methotrexate to subjects with active rheumatoid arthritis who have had an inadequate response to conventional disease-modifying anti-rheumatic drug therapy.

Medical History
1. Subjects with a history of malignant disease, including solid tumors and haematologic malignancies (except basal cell and squamous cell carcinomas of the skin that have been completely excised and are considered cured).
2. History of severe allergic or anaphylactic reactions or known drug hypersensitivity.
3. History of clinically significant (as determined by the Investigator) cardiac, endocrinologic, pulmonary, neurologic, psychiatric, hepatic, renal or hematologic insufficiency, or any major disease that could affect any of the efficacy assessments, in particular, joint pain and swelling (e.g., Parkinson’s disease, cerebral palsy, diabetic neuropathy).
4. Known active bacterial, viral, fungal, mycobacterial, opportunistic infection or other infection (including atypical mycobacterial disease, but excluding fungal infections of nail beds) or any major episode of infection requiring hospitalization or treatment with intravenous (IV) antibiotics within 4 weeks of Day 0.
5. Nursing mothers, pregnant women, or women who are planning to become pregnant while in the study.
Treatment History
6. Other clinical issues or laboratory results that, in the opinion of the Investigator or Biogen Idec, make the subject unsuitable for enrollment.

- Primary Outcome Measures
Name Time Method Primary outcome: clinical efficacy of BG00012 with methotrexate; specifically, the American College of Rheumatology (ACR20) response. To achieve ACR20 response, a 20% improvement compared to baseline is required for both<br>swollen and tender joint counts, as well as 3 out of 5 additional parameters: Subject's Global Assessment of Disease Activity, Investigator's Global Assessment of Disease Activity, subject's assessment of pain, Health Assessment Questionnaire-Disability Index (HAQ-DI), and high sensitivity C-reactive protein (hsCRP) or erythrocyte sedimentation rate (ESR).[Baseline and at 12 weeks]
