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

2018-04-01 · More patients discontinued telcagepant compared to rizatriptan (38.2 and 30.9%, respectively). Both treatments were well-tolerated with dry mouth, nausea, dizziness, and somnolence again appearing as the most common adverse events to CGRP antagonism.

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. 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 2018-04-01 · More patients discontinued telcagepant compared to rizatriptan (38.2 and 30.9%, respectively). Both treatments were well-tolerated with dry mouth, nausea, dizziness, and somnolence again appearing as the most common adverse events to CGRP antagonism. 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. 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.

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).

The percentages of patients with clinical adverse events, laboratory adverse events, or discontinuation because of a laboratory adverse event were also similar between treatments. Although Merck’s drug telcagepant and a follow-on compound showed promise, the company discontinued development of both because of liver toxicity. Other companies appear to be developing similar drugs, however, said Dr. Rapoport. The only factor that may hold them back is previous failures – in 2011 telcagepant was discontinued due to liver toxicity concerns.
