Summary

Chronic migraine patients treated with OnabotulinumtoxinA may experience breakthrough headaches, especially toward the end of their 12-week therapy. The addition of a CGRPmAb could help in decreasing or eliminating these episodes, but this combination is considered "experimental" by many payers, which often leads to a denial of coverage. Currently, there is no reference in the literature or data to support the treatment of chronic migraine with OnabotulinumtoxinA and CGRPmAbs (Aimovig, Ajovy, Emgality or Vyepti) combination therapy. This has resulted in many patients and providers having to settle for one or the other. Investigators hopes to provide crucial data and findings to support the addition of CGRPmAb in some chronic migraine patients currently on monotherapy OnabotulinumtoxinA.
