Title: A Randomized, Open-Label Study in the Asia-Pacific Region Comparing the Safety and Efficacy of Etanercept With Usual DMARD Therapy in Subjects With Rheumatoid Arthritis
Brief Summary: The purpose of this study is to compare the efficacy of etanercept with usual disease-modifying anti-rheumatic drug (DMARD) therapy in the treatment of moderate to severe rheumatoid arthritis (RA) over 16 weeks in the Asia Pacific region.


Options:
A: Inclusion Criteria:

* Have a diagnosis of rheumatoid arthritis (according to the 1987 ACR classification criteria OR a score of ≥6 as defined by the ACR/European League Against Rheumatism Classification and Diagnostic Criteria for rheumatoid arthritis ) for at least 6 months prior to screening
* Must have been treated with MTX 12.5-25 mg/week, for at least 6 weeks prior to screening. Doses of 10 to \< 12.5mg/week are allowed if there is documented intolerance
* Have moderately to severely active rheumatoid arthritis disease with at least 6 tender and 6 swollen joints
* CRP ≥1.2 times the upper limit of normal (central laboratory) or erythrocyte sedimentation rate of more than 28mm/hour
* Intolerant or inadequate response to treatment (ie, TNF blocker failure)≥1 licensed TNF-blocker therapies within 2 years of screening

Exclusion Criteria:

* Have a diagnosis of any other inflammatory arthritis or secondary, noninflammatory type of arthritis, such as psoriatic arthritis, lupus, gout, or ankylosing spondylitis
* Wheelchair bound or bedridden.
* Disease modifying antirheumatic drugs (DMARDs) other than MTX.
* Treatment with tocilizumab or any other anti-IL-6 investigational therapies at any time.
* Treatment with other biologics within 4-24 weeks (depending on the biologic)
* History of ongoing, chronic or recurrent infections or recent serious or life-threatening infection
* Known concurrent acute or chronic viral hepatitis B or C infection or human immunodeficiency virus (HIV) infection.
* Vaccinations (other than injectable influenza or pneumococcal) within 8 weeks prior to screening or plan to receive vaccines during the study
* Concurrent or history of malignancy with the exception of nonmelanoma skin cancer successfully treated more than 2 years prior to screening or cervical cancer successfully treated more than 5 years prior to screening.
* History of chronic alcohol abuse or drug addiction within the last 1 year or current drug addiction or use of illicit drugs.
B: Inclusion Criteria:

* Adult patients, ≥18 years of age
* Active rheumatoid arthritis of \>6 months duration
* Received permitted DMARDs each at a stable dose for at least 7 weeks prior to baseline

Exclusion Criteria:

* Rheumatic autoimmune disease or inflammatory joint disease other than rheumatoid arthritis
* Major surgery within 8 weeks prior to screening or planned within 6 months following randomization
* Unsuccessful treatment with a biologic agent, including an anti-TNF agent
* Previous treatment with tocilizumab
C: Inclusion Criteria:

* Diagnosis of RA
* Currently receiving an adequate dose of methotrexate (MTX) for treatment of RA
* Active RA at time of screening and baseline

Exclusion Criteria:

* Previous or current treatment with etanercept (ETN), other tumor necrosis factor-alpha inhibitors, or other biologic agents
* Concurrent treatment with a DMARD, other than MTX, at screening
* Receipt of any DMARD, other than MTX, within 3 months before screening
D: Inclusion Criteria:

* Patients with established diagnosis of low to moderate adult rheumatoid arthritis, currently on Disease Modifying AntiRheumatic Drugs (DMARDs) therapy for at least six months and not longer than 10 years

Exclusion Criteria:

* All the concomitant diseases or pathological conditions that could interfere and impact the assessment of the study treatment, or with the safety of the patient
* Previous clinical trials and previous biological therapy that could interfere with the results in the present clinical trial
* Patients must not have received any previous biological therapy for rheumatoid arthritis (RA)
