A Phase IIa clinical trial studying telcagepant for the prophylaxis of episodic migraine was stopped on March 26, 2009 after the "identification of two patients with significant elevations in serum transaminases".

A subsequent effort to identify novel CGRP receptor antagonists less likely to cause hepatotoxicity led to the development of ubrogepant. 2020-06-24 Olcegepant is a calcitonin gene-related peptide (CGRP) antagonist. In preclinical studies, olcegepant attenuated arterial dilation induced by CGRP or electrical stimulation. In a phase II clinical trial, olcegepant reduced the severity of headache in 60% of migraine sufferers and met secondary endpoints including headache-free rate and rate of sustained response. Telcagepant is orally available and several completed Phase III trials have revealed positive results. In several comparative studies of telcagepant and triptans, telcegepant did not appeared more effective than zolmitriptan or rizatriptan, although it had fewer triptan-related adverse events and … 2019-06-18 Two compounds, telcagepant [46] [47][48][49][50][51][52] and MK-3207 [53] have been discontinued due to hepatotoxic side-effects, olcegepant has been discontinued as an oral formulation was too Telcagepant is a novel oral CGRP receptor antagonist in development for the intermittent treatment of acute migraine, which does not constrict blood vessels and works via a mechanism that does not Small-molecule calcitonin gene-related peptide (CGRP) receptor antagonists have demonstrated therapeutic efficacy for the treatment of migraine. However, previously investigated CGRP receptor antagonists, telcagepant and MK-3207, were discontinued during clinical development because of concerns about drug-induced liver injury.

Telcagepant discontinued

Telcagepant (100) is a calcitonin gene-related peptide (CGRP) receptor antagonist which entered clinical trials for the treatment of acute migraine (Fig. 20, Table 22). 128 Development was terminated when elevated levels of the liver enzyme alanine transaminase were found in treated patients. In July 2011, Merck announced that it had discontinued clinical development of an earlier investigational oral CGRP antagonist, Telcagepant (MK-0974), after some patients showed evidence of liver toxicity. The pharmaceutical company Merck & Co., Inc was at the 14th International Headache Congress in September, talking again about the migraine drug Telcagepant.

Telcagepant (code name MK-0974) is a calcitonin gene-related peptide receptor antagonist which was an investigational drug for the acute treatment and prevention of migraine, developed by Merck & Co.. In the acute treatment of migraine, it was found to have equal potency to rizatriptan and zolmitriptan In addition, although telcagepant and BI 44370 were associated with moderate efficacy and low toxicity in acute intermittent treatment, research regarding these compounds has been discontinued due to hepatotoxicity concerns during long-term prophylactic use (Connor et al., 2011; Diener et al., 2011). Pooled together, all doses had a response rate of 60%. Onset of effect occurred 30 minutes post dose.

telcagepant across multiple doses (25–600 mg) identified no significant adverse events [57]. The most common adverse events observed were nausea, dizziness, and somnolence at the higher doses (300–600 mg). Clinical efficacy was not observed at doses under 300 mg, and as such, these doses were discontinued.
