Antagonist Antibodies Directed Against Calcitonin Gene-Related Peptide and Methods Using Same
The invention features methods for preventing or treating CGRP associated disorders such as vasomotor symptoms and/or headaches (e.g., migraine, cluster headache, and tension headache) by administering an anti-CGRP antagonist antibody. Compositions for use in the disclosed methods are also provided. Antagonist antibody G1 and antibodies derived from G1 directed to CGRP are also described.
1 .- 26 . (canceled)
27 . A method of decreasing a number of monthly headache hours experienced by a subject, comprising administering to the subject an amount of a monoclonal antibody that modulates the CGRP pathway, wherein the monoclonal antibody is in an amount effective to decrease the number of monthly headache hours by at least 20 after a single dose.
28 . A method of decreasing a number of monthly headache hours experienced by a subject, comprising administering to the subject an amount of a monoclonal antibody that modulates the CGRP pathway, wherein the monoclonal antibody is in an amount effective to decrease the number of monthly headache hours by at least 15% after a single dose.
29 . A method of decreasing a number of monthly headache days experienced by a subject, comprising administering to the subject an amount of a monoclonal antibody that modulates the CGRP pathway, wherein the monoclonal antibody is in an amount effective to decrease the number of monthly headache days by at least 3 after a single dose.
