Outcomes
Primary outcome [1] 5159 0
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
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).
Timepoint [1] 5159 0

Key exclusion criteria
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.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization will take place across all study sites using a centralized Interactive Voice Response System.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will take place across all study sites using a centralized Interactive Voice Response System. Subjects will be randomized after the Investigator has verified that they are eligible. Randomization will be stratified by screening rheumatoid factor (RF) status and region. Subjects will be randomized to receive placebo, BG00012 480 mg/day, or BG00012 720 mg/day. Subjects who are withdrawn from the study may be replaced.

Summary
Brief summary
BG00012 has been shown to be effective in reducing signs and symptoms of psoriasis and multiple sclerosis. BG00012 may be effective in the treatment of rheumatoid arthritis (RA) as well. The present study will test this concept in subjects with RA who have not responded adequately to methotrexate (MTX), the standard first-line oral agent for this disease.
