Hi Vaibhav,

❝ For modifed release formulation (Bioequivalence of partial AUC) […]


❝ Comparisons of HaVD and MDT can be evaluated by nonparametric calculations

❝ Which part of the curve bioequivalence needs to be established, upper or lower?

❝ Is it acceptable approach for EU submission.


Since you posted in the category Regulatives / Guidelines and asked specifically for a European submission:Personally I agree with the ‘Two Lászlós’ and think that these metrics are valuable indeed (though I don’t concur that nonparametrics are necessary). If you want to discuss these metrics, let me know and I will move this thread to the category NCA / Sham.

PS: Why did you upload the figure seven times in the lousy JPG-format (see there)? I removed them and uploaded an 8 bit PNG including the legend instead.
PPS: A salutation in posts is polite and never hurts.
