Description

Curator's Comment: Description was created based on several sources, including http://adisinsight.springer.com/drugs/800024645 http://www.medscape.com/viewarticle/735764_2

Telcagepant (MK-0974) is a calcitonin gene-related peptide receptor antagonist. Merck & Co was developing telcagepant for the treatment of pain. Telcagepant is an extremely potent CGRP antagonist with a Ki = 0.77 (0.07 nM). Telcagepant showed efficacy against acute migraines; however, different patient populations may show more beneficial effects with telcagepant versus triptans. In the acute treatment of migraine, Telcagepant was found to have equal potency to rizatriptan and zolmitriptan in two Phase III clinical trials. Merck & Co has now terminated development of the drug.

In Vitro Use Guide

Telcagepant (MK-0974) was very potent in E10 cell-based assay measuring inhibition of CGRP-stimulated cAMP production (IC50 = 2.2 nM), which was only shifted 5-fold (IC50 = 11 nM) in the presence of 50% human serum, suggesting a modest level of protein binding
