Olcegepant (BIBN-4096) est un antagoniste non peptidique puissant et sélectif du récepteur du peptide 1 lié au gène de la calcitonine (CGRP1) avec IC 50 de 0,03 nM et K i de 14,4 pM pour le CGRP humain.. Olcegepant (BIBN-4096) is a potent and selective non-peptide antagonist of the calcitonin gene-related peptide 1 (CGRP1) receptor with IC 50 of 0.03 nM and K i of 14.4 pM for human CGRP.

77 Olcegepant was discontinued because of difficulties in developing an oral formulation. Telcagepant (MK‐0974) was the first orally available CGRP‐RA. 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, 13 patients receiving telcagepant, but none on placebo, developed aminotransferase elevations more than threefold above normal; therefore, the trial was prematurely terminated. Of the 13 patients with liver enzyme elevation, 2 were symptomatic and had > 10-fold elevations above normal, with resolution after treatment was discontinued.

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 Chan KY et al., 2010, Characterization of the calcitonin gene-related peptide receptor antagonist telcagepant (MK-0974) in human isolated coronary arteries., J Pharmacol Exp Ther TTD : Telcagepant Version: 2020.06.01 2019-08-30 · 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 .

Meanwhile, in the photophobia freedom 2 hr postdose, the rank best 3 were BI 44370 TA, rimegepant, and telcagepant also. The detail information was showed in Tables 2 and 3. 3.2 Safety. Regarding primary safety outcomes, only rimegepant and telcagepant were higher than placebo in incidence of any adverse events in pair‐wise meta‐analysis

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). However, 13 patients receiving telcagepant, but none on placebo, developed aminotransferase elevations more than threefold above normal; therefore, the trial was prematurely terminated.
