Abstract:
Two-stage designs for the assessment of bioequivalence have been recently accepted in various regulatory authorities.However controlling type Ⅰ error rates around 5% at targeted power is still a great challenge for applying two-stage method.This paper reviewed the feature of present designs of the two-stage bioequivalence.The decision tree,nominal significance level,and sample size recalculation in previously published methods were also introduced in detail,which would be referential for domestic sponsors in the study of two-stage design bioequivalence.
