RegisterAbout "PK repeats" [Software]
Dear Helmut,
The rationale is not scientific, it's just paranoia. The fear is that the lab could be tempted to repeat the assay if bioequivalence is not demonstrated, particularly for Cmax, to try and get "better" results. No reason to do such a thing in BA trials when developing a new drug.
There is a lot of regulatory paranoia regarding BE trials, but one has to admit that this paranoia is fed by inspection results. Remember the results of French inspections which were presented at the EGA meeting some years ago (2007 I think): basically, critical observations in half of the dossiers inspected, including fraud or some level of data manipulation in one quarter of the dossiers inspected.
Best regards
Ohlbe
