 Maximum number of repeats in the BE study [Bioanalytics]

Is there any regulatory criteria/guidelines (other than ANIVSA) for limiting the number of repeats (i.e.subject samples) in Bioequivalence studies. I know that in ANIVSA resolution it was given that the percentage number repeat of should not more than 20% total number of samples analysed

 Maximum number of repeats in the BE study

Hi!

To my knowledge there is no explicit acceptable %-number for re-analysed samples in BE studies stated in any country's guideline.

best regards
Hermann

P.S.: But you are right with 20% for ANVISA:
Resolution - RE nº 896 of 29 May 2003 states

2. Analytical stage
e) the analytical protocol shall contain the criteria for the re-analysis of the samples; no more than 20% of the samples may be re-analyzed;

...and also don't forget this one:
i) the analytical protocol shall contain the sample's data reintegration criteria;

There was an update (RE nº 397 of 12 Nov 2004), but has not been translated into English yet and is not available - even in Portuguese - at ANVISA's website.

 Repeats in the BE study (ANVISA)

Dear Hermann!

❝ There was an update (RE nº 397 of 12 Nov 2004), but has not been translated into English yet and is not available - even in Portuguese - at ANVISA's website.


RE nº 397 is superseded by RE nº 1170 (19 April 2006, in Portuguese); still 20%.
