Hi everyone,

Regarding the FDA guidance on pre-dose concentration:

"If the predose concentration is less than or equal to 5 percent of Cmax value in that subject, the subjects data without any adjustments can be included in all pharmacokinetic measurements and calculations. If the predose value is greater than 5 percent of Cmax, the subject should be dropped from all BE study evaluations."

What if a subject has a pre-dose concentration in period 1? Should the subject still be kept or needs to be removed since he shouldn't have any pre-dose concentration in period 1.

Clinic shows no deviations and data was reviewed.

A central lesson of science is that to understand complex issues
(or even simple ones), we must try to free our minds of dogma and
to guarantee the freedom to publish, to contradict, and to experiment.
