Some philosophy [Power / Sample Size]
Hi All,
If to conduct a BE-study with alfa error 5% and power 80% it means that a customer has 5% risk to buy non-BE medication and a developer has 20% risk to reject bioequivalent drug.
So, if we failed BE-study because PK-parameters were out of acceptance range may be we were "unlucky" and fall into 20% risk?
I wonder if there are any ways to decrease risk except sample sizing?
