» Coming back to clopidogrel: Its high variability is mainly caused by both presystemic and first-pass metabolism. The EMA in its Q&A-document do not recommend reference-scaling based on unclear clinical implications. Don’t know what USFDA’s current thinking is. The product-specific guidance is quite old (08/2008) and was issued before RSABE first appeared as an option (04/2010). The FDA generally does not require a clinical justification (contrary to the EMA) and allows scaling for both AUC and C_max.

Question: wrt to EMA Q&A about clopidogrel not allowing widening on CMAX, can we plan full replicate BE study with BE Limit of 80.00-125.00% or two way cross over BE study needs to be performed?
