Title: A Randomized, Open-label Study In The Latin America Region Comparing The Safety And Efficacy Of Etanercept With Conventional Dmard Therapy In Subjects With Rheumatoid Arthritis.
Brief Summary: The purpose of this 2 phased, open-label study is to compare the safety and efficacy of etanercept with conventional Disease Modifying Antirheumatic Drug (DMARD) therapy in Latin American subjects with moderate to severe rheumatoid arthritis over 128 weeks. Phase 1 is a randomized 24 week treatment period; Phase 2 is an optional open-label 104 week period that allows the investigator to choose continuation with the phase I treatment or the addition, discontinuation or titration of other DMARD therapy already being utilized for the study.

* Diagnosis of RA according to the 1987 revised ACR Criteria for the Classification of RA for at least 6 months prior to screening
* Positive for rheumatoid factor or anti-cyclic citrullinated peptide (CCP) antibody, or both
* Active disease, defined as: CRP \>= 1.0 mg/dL; swollen joint count \>= 6 (66 joint count); tender joint count \>= 6 (68 joint count)
* Previous inadequate clinical response to at least one disease-modifying anti-rheumatic drug (DMARD) consisting of either methotrexate (MTX) or leflunomide (LFU)
* For patients currently receiving corticosteroids: Treatment at a stable dose during last 4 weeks prior to screening
* For patients currently receiving non-steroidal anti-inflammatory drugs (NSAIDs): Treatment at a stable dose during last 4 weeks prior to screening
* For patients currently receiving sulfasalazine or anti-malarials: Treatment initiated and continued for at least the last 6 months prior to screening and on a stable dose
* For patients of reproductive potential (males and females): Willing to use a highly effective birth control method for the duration of the study according to local guidelines

Exclusion Criteria:

* Pregnant, planning to become pregnant during the study, or breastfeeding
* Clinically significant abnormal laboratory values or abnormal ECG or vital signs
* History of anaphylactic reactions
* Rheumatic autoimmune disease other than RA, or significant systemic involvement secondary to RA (including but not limited to vasculitis, pulmonary fibrosis, or Felty's syndrome), however patients with secondary Sjogren's syndrome are eligible for the study
* History of or current inflammatory joint disease other than RA (e.g., gout, reactive arthritis, psoriatic arthritis, seronegative spondyloarthritis, Lyme disease) or other systemic autoimmune disorder (e.g., systemic lupus erythematosus, inflammatory bowel disease, scleroderma, inflammatory myopathy, mixed connective tissue disease, or other overlap syndrome)
* Current or recent (within 4 weeks prior to screening) infection, including signs, symptoms or serology of any infection, including HIV, hepatitis B or C, tuberculosis
* Administration of a live, attenuated vaccine within 1 month before dosing or anticipation that such a live attenuated vaccine will be required during the study
* Previous treatment with anti-TNF biologics or other biologic agents, including anti-CD20-directed therapy (e.g. rituximab), anti-IL6-directed therapy (e.g. tocilizumab), or T cell-directed therapy (e.g. abatacept)
B: Inclusion Criteria:

* Adults with moderate to severe rheumatoid arthritis on a stable dose of methotrexate who have inadequate response to Tumor Necrosis Factor (TNF) inhibitors.

Exclusion Criteria:

* Pregnancy, severe acute or chronic medical conditions, including serious infections or clinically significant laboratory abnormalities.
C: Inclusion Criteria:

* Diagnosis of Rheumatoid Arthritis (RA)
* Currently receiving a suboptimal response to a stable dose of methotrexate for treatment of Rheumatoid Arthritis (RA)
* Active Rheumatoid Arthritis (RA) at time of screening and baseline

Exclusion Criteria:

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

* Adult patient with established moderate to severe rheumatoid arthritis

Exclusion Criteria:

* All concomitant diseases or pathological conditions that could interfere and impact the assessment of the study treatment
* Previous clinical trials and previous biological therapy that could interfere with the results in the present clinical trials
