Summary

The purpose of this study is to determine the receptor occupancy (RO) associated with telcagepant (MK-0974) administration based on displacement of \[11C\]MK-4232 from the CGRP receptors in the brain using PET. The study enrolled healthy participants (Part I) and migraine patients (Part III). Due to a protocol amendment, study Part II was not conducted.
