[New Management of Cluster Headache].

Galcanezumab, a CGRP monoclonal antibody drug, has been approved by the U.S. Food and Drug Administration (FDA) for the prevention of recurrent cluster headaches. This was done after a randomized, double-blind, placebo-controlled trial found it to be effective and safe. Similarly sphenopalatine ganglion stimulation has been found to be effective and safe in a randomized, controlled trial as an acute treatment for chronic cluster headache. This article reviews the mechanisms of action of these therapies and their clinical trial results, clinical uses, and prospects in Japan.
