Peptide immunogens targeting calcitonin gene-related peptide (CGRP) and formulations thereof for prevention and treatment of migraine

Abstract

The present disclosure is directed to peptide immunogen constructs targeting portions of Calcitonin Gene-Related Peptide (CGRP), compositions containing the constructs, antibodies elicited by the constructs, and methods for making and using the constructs and compositions thereof. The disclosed peptide immunogen constructs have more than about 30 amino acids and contain (a) a B cell epitope having about more than about 7 contiguous amino acid residues from the CGRP receptor binding or activation regions of the full-length CGRP protein; (b) a heterologous Th epitope; and (c) an optional heterologous spacer. The disclosed CGRP peptide immunogen constructs stimulate the generation of highly specific antibodies directed CGRP for the prevention and/or treatment of migraine.
