It is recommended by the FDA that we can use coefficient of variance (CV) from previous study to calculate the smaple size for the new study, but I cant understand that which PK parameter (AUC(0-t), AUC(0-inf), Cmax) is used from previous study for the sample size of the new study? because I encountered large difference between CV's for AUC and Cmax from previous study.
