Dear D. Labes,

thanks for participating!

❝ ❝ replicate design in steady state (i.e., TTRR-RRTT)

❝ ^^^^

Something like this:


saturation phase     T       T     switch over         R       R

saturation phase     R       R     switch over         T       T

pre dose values   profile profile  pre dose values  profile profile

This is my interpretation of EMA’s MR-NfG (Section 4.1.2):

The inter-individual variability of the pharmacokinetic parameters of interest should be compared between the modified and immediate release formulation and the variability of the modified release formulation should not exceed that of the immediate release formulation. It may be valuable to assess the intra-individual variability. This could be achieved by either repeated measurements of the concentration profile at steady state or by performing a single dose study with replicate design.

(my emphasis)
