Notes: All data are geometric mean (gCV%) unless otherwise stated.
AUC0–inf, area under the concentration–time curve from time zero to infinity; AUC0–last, area under the concentration–time curve from time zero to the last quantifiable concentration; %AUCext, percentage of AUC0–inf obtained by extrapolation; CL, total body clearance; Cmax, maximum serum concentration; EOS, end-of-study; gCV, geometric coefficient of variation; λz, terminal elimination rate constant; PK, pharmacokinetic; t½, terminal elimination half-life; Tmax, time to maximum serum concentration; Vss volume of distribution at steady state.
*One patient in the CT-P63 1800 mg group was excluded from AUC0–last and AUC0–last/dose calculations because they were lost to follow-up at EOS visit.
