  • Data presented are number (%) of patients unless noted otherwise noted.

  • * Patients could appear in more than one column.

  • Occurring in ≥10% of patients in either golimumab dose group.

  • As previously reported by Smolen and colleagues,1 an additional patient in the placebo group who did not meet the early escape criteria died of pancreatic cancer. The resulting incidence is 1.73 (95% CI 0.04 to 9.65) and 1.73 (95% CI 0.04 to 9.66) per 100 pt-yrs of follow-up for death and other/all malignancies, respectively.

  • § Occurring in ≥1% of patients in either golimumab dose group.

  • Serious infections were observed in 5 (3.2%) patients through a total of 58 pt-years of follow-up pertaining to receipt of placebo, equating to an incidence of 8.66 (95% CI 28.1 to 20.22) per 100 pt-yrs of follow-up.

  • ** Occurring in ≥2 patients overall.

  • AE, adverse event; pt-years, patient-years of follow-up; RA, rheumatoid arthritis.
