0 hr Pre-dose concentration but less than 5% of Cmax [Regulatives / Guidelines]
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.
Thanks
John
