Currently, there are other novel CGRP receptor antagonists undergoing clinical trials, with little evidence of liver toxicity in the early phases, highlighting an exciting time for small molecule CGRP antagonist. A memo to study locations stated that telcagepant had preliminarily been reported to increase the hepatic liver enzyme alanine transaminase (ALT) levels in "11 out of 660 randomized (double-blinded) study participants." All study participants were told to stop taking the medication. 2017-01-25 Merck Delays Filing for Migraine Drug Over Potential Liver Toxicity April 22, 2009 A safety signal for elevated liver enzymes has been detected for Merck’s investigational calcitonin gene-related peptide antagonist telcagepant, causing the company to delay its targeted 2009 NDA filing for … 2021-03-23 the liver is the first internal organ to encounter a number of insults including ingested metals, drugs, and environ-mental toxicants (Klaassen, 2007).

It was hypothesized that the observed potential liver toxicity of telcagepant and MK-3207 was not an inherent consequence of CGRP receptor inhibition, because α-CGRP knockout mice do not develop liver problems, and because anti-CGRP monoclonal antibodies, such as erenumab, are not associated with liver safety concerns (Dodick et al., 2018; Goadsby et al., 2017; Hargreaves and Olesen, 2019; Walker et al., 2010).
