Dear Helmut and Elmaestro,

❝ You are right with the sequential designs. If I don't have a lot (!) of previous data, I made them already my new standard.

So, it sounds like that the sequential designs (Method C or D suggested by Potvin D, et al., 2008) have been widely acceptable for regulatory agents (FDA/EMA/Japan/etc.). However, I don't quite remember that there is any regulation mentioned the sequential designs for ABE study. Am I wrong about this? Thanks.
