	Hi colleagues, The EMEA guideline states that it is acceptable to use a two-stage approach when attempting to demonstrate bioequivalence. Can anyone enlighten me on this kind of study design, steps to be taken, stopping criteria or can we automatically switch to stage 2 if the BE fails at stage 1? Thanks and regards. Edit: Category changed. [Helmut]

	Dear Joy, EMA does not specify a particular method. One of them (Potvin et al. 2008) we have discussed numerous times in the forum. See e.g. this post. — Dif-tor heh smusma 🖖🏼 Довге життя Україна!
