Dear Ritesh Korat,

❝ Firstly monitor around 20% of first subject of the study.


Why wait till 20 %, if it is already visible after 2-3 runs that the concentrations are lower than expected ?

❝ if Cmax of both period in 14 (67% of 20) subjects out of that 20 subjects cross two QC level than no need of additional QC


Why 67 % ? Where did you take that figure from ?

IMHO what's important is not just how many subjects have a Cmax below the MQC sample - but also how much below it is.

❝ and if its not than add one more QC between LQC and MQC.


Or adjust the concentration of the existing MQC. The guidelines also gives this option.

Regards
Ohlbe
