If n >2, data are mean ± standard deviation (geometric mean), except for tmax, which is reported as median (range). If n ≤ 2, individual values are listed.

5-FU, 5-fluorouracil; AUC0-t, area under the plasma drug concentration–time curve up to time “t”; AUC0-τ, area under the plasma drug concentration–time curve over the dosing interval; CLss/F, apparent total body clearance after oral administration at steady state; Cmax, maximum observed plasma concentration; Cmin, minimum (trough) steady-state plasma concentration; mFOLFOX6, oxaliplatin, leucovorin calcium (folinic acid), and 5 fluorouracil; nab, nanoparticle albumin-bound; NC, not calculable; t1/2, half-life; tmax, time to maximum concentration.
