Hi Brus,

❝ If one test and two references of different regions are tested in a bioequivalence study, is it necessary a α adjustment?


❝ In my case, we want to demonstrate if the test product is bioequivalent to R1 (European product reference) or if test product is bioequivalent to R2 (Reference product in the United Kingdom).


❝ If I have not misunderstood, in this case, alpha should be penalized, even if they are from different regions and to market in different regions because of the word "OR"?


❝ Is there a way to not penalize alpha? If the "O" is changed to "AND"? Executing two different clinical trials (one for Europe and one for the UK)?


Here's a different way to look at it:
Can the same patient(s) be affected by your two tests? If yes, it is safer to use correction. If no, no correction should be necessary.

Pass or fail!
