Several lines of evidence suggest that a calcitonin-gene related peptide (CGRP) receptor antagonist may serve as a novel abortive migraine treatment. Here we present data on a human cell line and isolated human vessels for such an antagonist, BIBN4096BS. On SK-N-MC membranes, radiolabelled CGRP was displaced by both CGRP-(8-37) and BIBN4096BS, yielding pK(i) values of 8.5 and 11.4, respectively. Functional studies with SK-N-MC cells demonstrated that CGRP-induced cAMP production was antagonised by both CGRP-(8-37) and BIBN4096BS with pA(2) values of 7.8 and 11.2, respectively. Isolated human cerebral, coronary, and omental arteries were studied with a sensitive myograph technique. CGRP induced a concentration-dependent relaxation that was antagonized by both CGRP-(8-37) and BIBN4096BS in a competitive manner. CGRP was a weaker agonist on coronary arteries as compared to intracranial arteries; however, BIBN4096BS was an equally effective antagonist. In human omental arteries, CGRP did not induce relaxation. BIBN4096 had a pA(2) value of 10.1 in cerebral and 10.4 in coronary arteries. The results of clinical trials with BIBN4096BS for acute migraine attacks are awaited with great interest.
