Capsaicin-induced dermal vasodilatation (CIDV) inhibition as surrogate pharmacodynamic marker; no animal migraine model
“A specific animal model for the evaluation of prophylactic effects of atogepant on migraine was not provided by the applicant. As a surrogate pharmacological parameter for clinical efficacy of atogepant in the prophylaxis of migraine, inhibition of capsaicin-induced dermal vasodilatation (CIDV), an effect considered to be mediated largely by release of CGRP, was used by the applicant.”
