Dew, I think you meant to say CRP instead of CGRP. The latter is the peptide strongly implicated in dural vasodilation related to migraine attacks. I will venture to say that Servier does not want them to publicly state the precise value?
I believe that when they first announced the new trial they said that the cutoff on the original trial was 2. But I don't believe it was in my notes - so it is subject to memory errors.
