Parameter estimates are presented as median (IQR) or point estimates for parameters generated from composite profiles. BP multiple dose estimates were calculated from concentrations following the last dose. Matrix:BP ratios are presented as the geometric mean AUC0-24h ratio (%CV) for SF after a single dose or geometric mean AUC0-24h ratio for RT and SF after multiple doses.
