  1. *Percentages are based on the number of patients in the double-blind study safety set who received the given treatment in either Period I or Period II. Hence, patients who switch at week 24 are included in the N count for both treatments
  2. Each patient was counted only once for each condition
  3. RA rheumatoid arthritis, RP reference product, TEAE treatment-emergent adverse event, TESAE treatment-emergent serious adverse event
