Brief summary

The purpose of this study is to assess the antibody formation to Enbrel liquid in subjects with Rheumatoid Arthritis

Detailed description

The purpose of this study is to assess the rate of anti-etanercept antibody formation in a larger sample of subjects on liquid etanercept than the previous study, 20020378, in a minimum of 400 subjects receiving etanercept liquid for the first time, with and without concomitant MTX therapy. The rate of neutralizing antibodies to liquid etanercept will also be assessed.
