Acute Response Capsaicin Flare Study

2014-08-27 03:12:48 | BioPortfolio

Summary

Prior to administering PF-04427429 to patients we wish to increase the understanding of functional effects associated with calcitonin gene related peptide (CGRP) pathways. This study will examine whether it is possible for a single dose of PF-04427429 to acutely attenuate a capsaicin induced flare response. This will contribute to 'Proof of Mechanism' for this molecule and data from this study will help inform dose setting on the future phase II clinical trials.
