Telcagepant has non-linear pharmacokinetics after oral doses with greater than dose-proportional increases in AUC 0–∞. The non-linear pharmacokinetics is probably a result of saturation or inhibition of first-pass metabolism. Seven gepants have been studied in migraine; IV olcegepant was not further developed due to formulation issues and development of BI 44370 TA, MK-3207 and telcagepant were discontinued due to hepatotoxicity.

MK-0974 (telcagepant), a new oral antagonist of calcitonin gene-related peptide receptor, compared with zolmitriptan for acute migraine En klinisk fas III-studie har visat att telcagepant mot migrän är lika effektivt som colitis, the antibiotic should be discontinued and appropriate therapy instituted. 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. Please note that a pediatric investigational plan is approved by PDCO for telcagepant. As a result of this action, pediatric development will be discontinued.

More patients discontinued telcagepant 300 mg (38.2%) than rizatriptan 10 mg (30.9%) Phase II‐III Olcegepant (BIBN-4096) is a potent and selective non-peptide antagonist of the calcitonin gene-related peptide 1 (CGRP1) receptor with IC50 of 0.03 nM and Ki of 14.4 pM for human CGRP.

Telcagepant has been investigated for the treatment of Migraine. It is an antagonist of the receptor for calcitonin gene-related peptide (CGRP), a primary neuropeptide involved in the pathophysiology of migraine. Merck Updates Status of Clinical Development Programs for Investigational CGRP Receptor Antagonist Treatments for Acute Migraine; MK-3207 Clinical Development Discontinued Company Presenting New MK0974 (Telcagepant) for Migraine Prophylaxis in Patients With Episodic Migraine (0974-049) - Study 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.

Results of this study support further evaluation of telcagepant in 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). 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 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 The only factor that may hold them back is previous failures – in 2011 telcagepant was discontinued due to liver toxicity concerns.

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, which were evaluated in some clinical trials about abortive treatment of migraine, had not reported cardiovascular events (Connor et al., 2011 ; Connor et al., 2009 ; Hewitt, Martin, et al., 2011 ; Ho et al., 2010 , 2012 ; Ho, Ferrari, et al., 2008 ; Ho, Mannix, et al., 2008 ). However, previously investigated CGRP receptor antagonists, telcagepant and MK-3207, were discontinued during clinical development because of concerns about drug-induced liver injury.

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.
