Dear all!

The eagle has landed. The final BE-Guideline was published today.
The Guideline will be effective with 1 August 2010.

Fascinating!

[…] the 90% confidence interval for the ratio of the test and reference products should be contained within the acceptance interval of 80.00-125.00%. To be inside the acceptance interval the lower bound should be ≥80.00% when rounded to two decimal places and the upper bound should be ≤125.00% when rounded to two decimal places.
Funny. 79.995%-125.004% is bioequivalent, but your software will print out “Bioequivalence not shown.” Time for a revision of Phoenix/WinNonlin.
No statistical test for any effect (carry-over, period, treatment), as well as no confidence intervals.
Two-stage design: 94.12% confidence interval given as an example for the combined analysis. That’s the one of Potvin et al. (based on Pocock’s).
Interesting section on exclusion of subjects.
Scaling for C_max made it, but the widening of the acceptance range is limited to a maximum of 69.84–143.19% (CV_ref≤50%).The suggested method is (following the terminology of Tóthfalusi et al.) ABEL (Average Bioquivalence with Expanding Limits). Like in the U.S. a constraint of 80.00%-125.00% is set to the GMR.
t_max is back (instead of partial AUC truncated at t_max,ref) – but no statistical analysis (“no apparent difference in median t_max and its variability”).
C_ss,min has vanished.
