Dear Dan!
Should read ‘A redosing study may be acceptable for the FDA – but still they hate it.’
I’ve heard about this ‘method’ – do you have a reference? Assuming a normal distribution (after transformation) mean ±3SD covers 99.73% of the data. In other words, the sample size should be 370 in order to be able to ‘catch’ a single outlier.
Canada’s approaches are more reasonable, IMHO (cave: e.g., nonparametrics!).

❝ Based on data from the pivotal study, an acceptance range for the ratios - mean ±3 standard deviations - should be calculated for AUC and Cmax using the log transformed data.
