Data are expressed as mean ± SD unless otherwise specified. Tmax is expressed as median (range).
For subjects with AUC_%Extrap of >20%, AUC0–∞, t1/2, and AUC_%Extrap were not descriptively analyzed. PK parameters, including AUC0–∞, t1/2, and AUC_%Extrap, were descriptively analyzed for 7 subjects in the 100-mg group.
