Dear All,

Recently I carried out one study in the ER formulation for USFDA. The results are very good for the Cmax and AUCinf but the study fails marginally in lower CI in AUCt that is 79.28. The failure in this study is due to the presence of two outlier in the whole study. If we remove these outliers the study qualify the BE criteria for all the three parameters. But as we all know that USFDA don’t encourage the outliers test and its exclusion from the study.
Now we have only option to save our study otherwise we have to dump the whole study. The only option is if we remove the AUCt and AUCinf from the from two subjects whose %AUCextrap value is more than 20% and keeping Cmax and Tmax untouched. Our study qualifies the BE criteria of 80-125%.
So please suggest if we can do in same line as I am thinking or there are any other ways to save our study.
Hope for your positive reply.

Sam
