Dear Nirali,

❝ Shall it be appropriate design to evaluate reference variability for EU regulatory? :confused:

This was not the approach recommended at the EGA meeting last October. The preferred approach was to have a 3- or 4-period replicate study, with the reference administered twice, and the test once or twice. It seems that they are afraid that you might run a messy trial to show a high variability with the reference alone, and use these results to justify wider acceptance limits in a clean 2x2 trial with test and reference afterwards.

Regards
Ohlbe
