Title: A Multi-center, Randomized, Double-Blind, Active-Controlled Study Evaluating Efficacy and Safety of Etanercept 50 mg Twice Weekly (BIW) in Rheumatoid Arthritis Subjects Who Are Sub-optimal Responders to Etanercept 50 mg Once Weekly (QW)
Brief Summary: The purpose of this study objective will be to evaluate the efficacy and safety of etanercept 50 mg BIW in RA subjects who showed a sub-optimal response to standard dose etanercept (50 mg QW) and concomitant methotrexate therapy.

  * Positive PPD \>5mm, treated for at least 28 days with INH.
* Subjects with an Erythrocyte sedimentation rate (ESR) of less than or equal to 10 and a tender and swollen joint count of at least 10 and does not qualify for the study using the DAS28, will be allowed to use the DAS28-CRP rather than the traditional DAS28 to determine eligibility.

Exclusion Criteria:

* Previous intolerance to methotrexate (unless able to tolerate at least 10 mg/week)
* Sensitivity to study medications
* Previous treatment with methotrexate, sulfasalazine or hydroxychloroquine in combination with each other for longer than 4 weeks duration. No combination use is allowed within 4 weeks of screening.
