Overview
Brief Summary
This is an open label, multicenter study for extended treatment of patients who have participated in the Immunex clinical study 016.0012. The primary objective of this study is to evaluate the long term safety of etanercept (TNFR:Fc) in patients with early stage rheumatoid arthritis.

Outcomes
Primary Outcomes
Total Exposure to Etanercept With Gaps
Time Frame: Up to 8 years
Total participant exposure to etanercept (Enbrel) with gaps, calculated as the sum of the times on treatment for all participants. Gaps of up to 14 days from the last treatment in a previous Etanercept study were ignored in calculating time on treatment.
Total Exposure-Adjusted Rate of Malignancies
Time Frame: Up to 8 years
Exposure-adjusted rate of malignancies, excluding nonmelanoma skin cancers, occurring on study within 30 days of the last dose of etanercept
Total Exposure-Adjusted Rate of Deaths
Time Frame: Up to 8 years
Rate of deaths within 30 days of the last dose of etanercept, adjusted for total exposure to etanercept
Total Exposure Adjusted Rate of Serious Infectious Events
Time Frame: Up to 8 years
Exposure-adjusted rate of serious infectious events (associated with hospitalization or IV antibiotics) occurring on study within 30 days of the last dose of etanercept
Total Exposure Adjusted Rate of Lymphomas
Time Frame: Up to 8 years
Rate of lymphomas occurring on study within 30 days of the last dose of etanercept, adjusted for total exposure to etanercept
Malignancy
Time Frame: Up to 8 years
Occurrence of one or more malignancies within the participant on study within 30 days of the last dose of etanercept
Lymphoma
Time Frame: Up to 8 years
Occurrence of one or more lymphomas on study within 30 days of the last dose of etanercept
Serious Infectious Event
Time Frame: Up to 8 years
Occurrence of one or more serious infectious events within the participant on study within 30 days of the last dose of study medication
Total Exposure Adjusted Rate of Serious Adverse Events
Time Frame: Up to 8 years
Rate of serious adverse events adjusted to total exposure to etanercept (events / exposure \* 100)
Death
Time Frame: Up to 8 years
Death of the participant on study up to 30 days after the last dose of etanercept
