Dear Martin,

I’m with you in the definition of data sets (especially PKAS(b) etc. etc.)…
The important point is an a-priori strategy, which has to be adapted according to the PK characteristics of the drug, etc.

❝ regarding the importance of FADS and PADS: the FADS should reflect the clinical situation in practice better than the rather artificial PADS and is according to my point of view more important.

Yes, but phase I trials never reflect the clinical situation.
IMPs in a BE study are not labeled for sole use in healthy male Caucasian^* subjects, preferably non-smokers of a BMI [19-27] fasting four hours after administration together with 150 mL non-carbonated water of ambient temperature avoiding methyl-xanthine containing food and beverages as well as grapefruit juice, charcoal broiled meat and broccoli during the study (did I forget something?).
A properly designed BE study should be powered to be able to detect differences between formulations in the smallest possible number of subjects – which we hope to attain by a high degree of standardization. This has nothing in common with the clinical situation.

❝ […] thanks for the very interesting discussion

Same to you!

• ‘Caucasian’ is an outdated racist concept and has nothing to do with (pharmaco)genetics…
