  • The primary PK endpoints of the observed AUC and Cmax,ss in patients treated with CT-P13 and INX at steady state were analysed using an analysis of covariance with treatment as a fixed effect and region and baseline BASDAI score fitted as covariates. Point estimates and 90% CI for differences on the log scale were exponentiated to obtain estimates for ratios of geometric means on the original scale.

  • ADA, anti-drug antibodies; AUC, area under the concentration-time curve; Cmax,ss, observed maximum steady state serum concentration; CI, confidence interval; INX, innovator infliximab; PK, pharmacokinetics.
