Conclusions.- Two doses of 300-mg telcagepant, administered 2 hours apart, did not appear to exacerbate spontaneous ischemia and were generally well tolerated in a small cohort of patients with stable coronary artery disease. Results of this study support further evaluation of telcagepant in patients with stable coronary artery disease.

For the three patients who discontinued due to an adverse event occurring within 48 hours of telcagepant , the adverse events were somnolence (one patient), chest discomfort (one patient) and deep vein thrombosis (one patient, already described above).

Olcegepant | C38H47Br2N9O5 | CID 6918509 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities Atogepant is chemically distinct from prior oral CGRP receptor antagonists, notably telcagepant and MK‐3207, which were discontinued because of drug‐induced liver injury (DILI). 16 The efficacy and safety of atogepant in migraine prevention was demonstrated in a phase IIb/III clinical trial conducted subsequent to this trial in which treatment with atogepant, compared with placebo 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.

It is an antagonist of the receptor for calcitonin gene-related peptide (CGRP), a primary neuropeptide involved in the pathophysiology of migraine. Merck discontinued a CGRP receptor antagonist, telcagepant, because of liver toxicity in 2011.

A subsequent effort to identify novel CGRP receptor antagonists less likely to cause hepatotoxicity led to the development of ubrogepant. 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 drug-related adverse enents. 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 However, previously investigated CGRP receptor antagonists, telcagepant and MK-3207, were discontinued during clinical development because of concerns about drug-induced liver injury. A subsequent effort to identify novel CGRP receptor antagonists less likely to cause hepatotoxicity led to the development of ubrogepant. Conclusions.- Two doses of 300-mg telcagepant, administered 2 hours apart, did not appear to exacerbate spontaneous ischemia and were generally well tolerated in a small cohort of patients with stable coronary artery disease.
