  • a The concentration of brivanib was determined with an achiral LC-MS/MS method. TRA in rat and monkey plasma was determined by LSC. TRA in human plasma was determined by accelerator mass spectrometry (Mekhail et al., 2010).

  • b The pharmacokinetic parameters of brivanib and plasma TRA in humans were reported in a separate article and are included here for comparison (Mekhail et al., 2010).
