Title: A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Etanercept in Subjects With Moderately Active Rheumatoid Arthritis Despite DMARD Therapy
Brief Summary: This study is designed to evaluate the effectiveness of adding etanercept to disease modifying anti-rheumatic drug (DMARD) therapy in patients with moderately active Rheumatoid Arthritis (RA).


Options:
A: Inclusion Criteria:

* male/female, 18-75 years old, inclusive
* diagnosis of adult-onset RA
* had active disease
* had received methotrexate
* on a stable dose of folic acid

Exclusion Criteria:

* contraindication for methotrexate or anti-TNF
B: Inclusion Criteria:

* patients at least 18 years of age with moderate to severe active RA for at least 6 months;
* inadequate response to current anti-rheumatic therapies, including 1 or more traditional DMARDs;
* stable DMARD therapy for at least 8 weeks before entering study;
* patients of reproductive potential must be using reliable methods of contraception.

Exclusion Criteria:

* major surgery (including joint surgery) within 8 weeks before entering study, or planned surgery within 6 months after entering study;
* patients who have previously failed treatment with an anti-tumor necrosis factor agent;
* women who are pregnant or breast-feeding.
C: Inclusion Criteria:

* Adult patients, ≥ 18 to \< 65 years of age
* Rheumatoid Arthritis (RA) of \> 6 months duration at baseline (American College of Rheumatology criteria)
* Willing to receive immunization with pneumococcal polysaccharide and tetanus toxoid adsorbed vaccines
* Previous immunization with pneumococcal polysaccharide must have occurred ≥ 3 years of baseline, with tetanus containing vaccine ≥ 5 years
* Methotrexate therapy for at least 8 weeks prior to baseline at stable dose of 7.5-25 mg/week (oral or parenteral)
* Other disease-modifying antirheumatic drugs (DMARDs) must be withdrawn before baseline
* Oral corticosteroids must be at stable dose of \< 10 mg/day prednisone or equivalent
* Body weight ≤ 150 kg at screening

Exclusion Criteria:

* Major surgery (including joint surgery) within 12 weeks prior to baseline or planned major surgery within 8 weeks after baseline
* History of or current inflammatory joint disease or rheumatic autoimmune disease other than RA
* Pre-existing central nervous system demyelinating or seizure disorders
* Active current or history of recurrent bacterial, viral fungal, mycobacterial and other infections
* Any major episode of infection requiring hospitalization or treatment with intravenous antibiotics within 4 weeks prior to baseline or oral antibiotics within 2 weeks prior to baseline
* Active tuberculosis requiring treatment within 3 years prior to baseline
* Primary or secondary immunodeficiency (history or currently active)
* Intra-articular or parenteral corticosteroids within 4 weeks prior to baseline
* Previous treatment with RoActemra/Actemra
D: Inclusion Criteria:

* Male or female ≥18 and ≤80 years of age at time of screening
* Diagnosed with rheumatoid arthritis as determined by meeting 1987 American College of Rheumatology (ACR) classification criteria and has had rheumatoid arthritis for at least 6 months
* Moderate rheumatoid arthritis during screening, as defined by a disease activity score (28 joint) calculated using the C-reactive protein formula (DAS28-CRP) \> 3.2 and ≤ 5.1
* Active rheumatoid arthritis defined as ≥ 3 swollen joints (out of 28 joints examined) and ≥ 3 tender/painful joints (out of 28 joints examined) at screening and baseline. (A full 66/68 count joint count will be performed at baseline, but only joints in the 28-count joint count will be considered for eligibility. The 28-joint count consists of the finger joints excluding the distal interphalangeal joints, the wrists, elbows, shoulders, and knees)
* Must be currently taking a DMARD such as methotrexate, sulfasalazine, leflunomide, minocycline, and/or hydroxychloroquine

Exclusion Criteria:

* Prosthetic joint infection within 5 years of screening or native joint infection within 1 year of screening
* Class IV rheumatoid arthritis according to ACR revised response criteria
* Any active infection (including chronic or localized infections) for which anti-infectives were indicated within 28 days prior to first investigational product dose
* Previously used more than one experimental biologic DMARD. Patient with prior use of no more than one experimental biologic is permitted if the subject received no more than 8 weeks of treatment. The use of the experimental biologic must not have occurred within 2 months of the first dose of investigational product
* Previously used more than one commercially available biologic DMARD. Subject with prior use of no more than one commercially available biologic is permitted if the patient received no more than 8 weeks of treatment and did not discontinue because of lack of effect. The use of the biologic must not have occurred within 2 months of the first dose of investigational product. Acceptable prior use of biologics include the following examples:
* No more than 4 injections of adalimumab
* No more than 8 (50 mg) injections of etanercept
* No more than 2 infusions of infliximab
* No more than 2 infusions of abatacept
* Additional inclusion (exclusion) criteria may apply
