Averages are presented as mean ± SD except for tmax, which is presented as median (min, max); ND, not determined; Cmax, maximum observed concentration after infusion/injection; tmax, time at which Cmax is observed after infusion/injection; AUC(0,56 days), area under the serum concentration–time curve from time 0 to study day 56 (last observation); AUC(0,∞), area under the serum concentration–time curve from time 0 to infinity; CL or CL/F, systemic clearance; Vss, volume of distribution at steady state; t1/2, terminal phase elimination half-life.
