Migraine preventive therapy—Who is eligible? What are the goals?

Migraine is associated with a substantial economic cost, yet is underdiagnosed and undertreated, and often aggravated by medication overuse. New effective and safe preventive therapies are now available and promise to transform the lives of patients with migraine. Patient eligibility for these new preventives and the treatment goals were discussed at a satellite symposium at EAN 2021.

Migraine is associated with substantial socioeconomic burden,1 said Professor Zaza Katsarava, University of Essen-Duisberg, Germany. So, there is no doubt that migraine should be treated.

Migraine is underdiagnosed and undertreated

 

Who is eligible for migraine preventive therapy?

A patient with migraine is eligible for preventive treatment if they experience at least 4 monthly headache days/month resulting in some disability. This is according to the American Headache Society (AHS) consensus position statement on integrating new migraine treatments into clinical practice.2

However, migraine is underdiagnosed and undertreated,2,3 with only 2–14% of patients eligible for preventive therapy receiving a preventive.4

Less than 14% of patients eligible for preventive therapy receive a preventive

 

What are the goals of preventive treatment?

Professor Hans-Christoph Diener, University of Essen-Duisberg, Germany explained that the goals for migraine preventive treatment include:

  • Reduction in the frequency of migraine episodes
  • Reduction in the severity of episodes
  • Shorter duration of attacks
  • Fewer non-headache symptoms
  • Reduced use of acute medication2

Therapies targeting calcitonin gene-related peptide are meeting the goals for preventive therapy

He highlighted evidence demonstrating that new therapies targeting calcitonin gene-related peptide (CGRP) are meeting the goals of preventive therapy.5 In patients with episodic or chronic migraine, anti-CGRP monoclonal antibody:

  • Reduces the frequency of migraine headache days6
  • Reduces headache severity7
  • Reduces headache duration7
  • Alleviates migraine-related symptoms8
  • Potentially alleviates disabling non-pain symptoms6

 

The challenge of medication overuse

Medication overuse worsens migraine

The management of patients with migraine is complicated by medication overuse.

In the United States, 23% of people with chronic headache use acute medications every day,9 and approximately 15% of people with migraine meet the criteria for medication overuse,10 said Professor Diener.

It is important to address any medication overuse when managing patients with migraine, he added, because of its association with medication overuse headache, disability, and migraine progression,10 a lower quality of life,11 and higher socioeconomic cost.12
