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.

However, the clinical development of telcagepant was discontinued because of hepatotoxicity concerns, and the development of several other CGRP receptor antagonists has also been discontinued because of safety concerns, formulation issues or unknown reasons [ 56 ]. 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. 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. 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, significantly decreased monthly migraine days over 12 weeks.

As a result of this action, pediatric development will be discontinued. Regardless, Merck discontinued the development of telcagepant and another compound MK-3207 in July 2011 due to liver toxicity. 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. The pharmaceutical company Merck & Co., Inc was at the 14th International Headache Congress in September, talking again about the migraine drug Telcagepant. And hopes that Telcagepant will see the light of day aren’t dead yet. After concerns about using Telcagepant as a migraine preventative, Merck has moved ahead with trials using the new drug […] Merck's ($MRK) headaches in developing migraine drugs continue.

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. Pain relief at 2 h was 68%, 48%, and

Company Presenting New Safety and Efficacy Data for Telcagepant at the 14th International Headache Congress. PHILADELPHIA, PA, USA | September 10, 2009 | Merck & Co., Inc. today updated the status of the clinical development programs for telcagepant (MK-0974) and MK-3207, the Company's investigational oral calcitonin gene-related peptide (CGRP) receptor antagonists for the intermittent 2015-04-29 Pooled together, all doses had a response rate of 60%. Onset of effect occurred 30 minutes post dose. Adverse events happened in 20% vs 12% in those receiving placebo.

Other companies appear to be developing similar drugs, however, said Dr. Rapoport. 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).

Telcagepant (MK‐0974) was the first orally available CGRP‐RA.

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". taking telcagepant once daily for seven days for the preve ntion of menstrually related migraine were found to have elevations in liver enzymes ≥ 3 times the upper limit of normal.

Adverse events happened in 20% vs 12% in those receiving placebo. 77 Olcegepant was discontinued because of difficulties in developing an oral formulation. Telcagepant (MK‐0974) was the first orally available CGRP‐RA. Telcagepant (INN) (code name MK-0974) is a calcitonin gene-related peptide receptor antagonist which was an investigational drug for the acute treatment and … Results Telcagepant was generally well tolerated: 66/2660 (2.5%) on telcagepant and 36/1326 (2.7%) on placebo discontinued because of a clinical adverse event.
