This Medfyle was published more than two years ago. More recent Medfyle on this topic may now be available.

Key messages

  • There were no significant differences in treatment response between patients treated with a CGRP monoclonal antibody to the receptor or with a monoclonal antibody to the CGRP ligand.
  • Thus, inhibiting the ligand or inhibiting the canonical receptor are equally effective in reducing headache frequency and improving quality of life.
  • Limitations include small sample size of the ligand receptor inhibitor cohort and lack of generalizability of data to patients outside of a large tertiary Headache center.
