  • Publication number: 20220363770
    Abstract: The present invention relates to antagonist antibodies of the human calcitonin gene-related peptide (CGRP) receptor as well as bispecific antigen binding proteins derived from the anti-CGRP antibodies that bind to and inhibit both the human CGRP receptor and another target, such as the human pituitary adenylate cyclase activating polypeptide type I receptor (PAC1) receptor. Pharmaceutical compositions comprising the anti-CGRP receptor antibodies and bispecific antigen binding proteins as well as methods for producing them are also disclosed. Methods of using the anti-CGRP receptor antibodies and bispecific antigen binding proteins to ameliorate, treat, or prevent conditions associated with the CGRP and PAC1 receptors, such as chronic pain, migraine, and cluster headache, are also described.
