CGRP som läkemedelsmål vid behandling av migrän - DiVA

Background.— Tript Telcagepant 140 mg was administered once daily at bedtime for 7 consecutive days each month, beginning at the onset of menses, for up to 6 months. Dosing could begin up to 3 days prior to menses onset if prodromal symptoms reliably predicted onset of menses. 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. A Phase IIa clinical trial studying telcagepant for the prophylaxis of episodic migraine 2015-04-29 Although the clinical development of telcagepant has been discontinued because of liver toxicity concerns, development of other CGRP receptor antagonists, such as BMS‐927711 and BI 44370 TA, is ongoing. These agents may prove useful for the treatment of patients who do not respond to triptans or indeed as adjunct treatments for acute migraine. 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.

Telcagepant discontinued

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. The drug giant revealed today that it has kicked to the curb its late-stage drug telcagepant, a once-touted experimental drug for Discontinued Endocrine disorders; Migraine Most Recent Events 24 Jun 2018 Biomarkers information updated 29 Jul 2011 Discontinued - Phase-I for Migraine in Belgium (PO) 29 Jul 2011 Discontinued - Phase-II/III for Migraine in USA (PO) 2006-10-26. 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. CGRP and its receptors are found in areas of the central and peripheral nervous system that are important for the These three gepants were discontinued because of different reasons.

Dosing could begin up to 3 days prior to menses onset if prodromal symptoms reliably predicted onset of menses. 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%.

CGRP som läkemedelsmål vid behandling av migrän - DiVA

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.

CGRP som läkemedelsmål vid behandling av migrän - DiVA

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. 17 Atogepant is in phase III development for 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. Regardless, Merck discontinued the development of telcagepant and another compound MK-3207 in July 2011 due to liver toxicity.

Of the 13 patients with liver enzyme elevation, 2 were symptomatic and had > 10-fold elevations above normal, with resolution after treatment was discontinued. Find all the evidence you need on "Telcagepant" via the Trip Database. Helping you find trustworthy answers on "Telcagepant" | Latest evidence made easy 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. 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. The percentages of patients with clinical adverse events, laboratory adverse events, or discontinuation because of a laboratory adverse event were also similar between treatments.

However, previously investigated CGRP receptor antagonists, telcagepant and MK-3207, were discontinued durin 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.

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.
