Hi John,

❝ Has FDA ever published (or presented) data of withinsubject CV from test and reference from submitted full replicate studies?

Yes. I’m too lazy to search as well. Maybe I dig out the link later on.* It was in the good (?) ol’ days when FDA was interested in subject-by-formulation interaction and requested replicate studies. The data sets are somewhere at FDA’s site in TXT-format. No CVs, so you have to run the analyses yourself. Only the classes of drugs are given.

B. The following data show that the test formulation has a higher intrasubject variability than the reference formulation (s_WT /s_WR ratio > 1.5)
AUC: Drugs # 15a, 15b, 15c, 15e
Cmax: Drugs # 15a, 15c, 15e, 15f, 16e, 16f

C. The following data show that the test formulation has a lower intrasubject variability than the reference formulation (s_WT /s_WR ratio < 0.667)
AUC: Drugs # 1, 5, 7
Cmax: Drugs # 1, 7, 14c, 14d

Too bad that data sets 14, 15, 16 are not online…

BTW, following [msg]this thread[/msg] about data exclusion:
Drug 1: AUC_t (n=156), AUC_∞ (n=155)
Drug 2: AUC_t (n=98), AUC_∞ (n=92)
Drug 3a: AUC_t (n=140), AUC_∞ (n=138)
