Commentary: CGRP Monoclonal Antibodies for Migraine, December 2023

Depression is one of the most common comorbidities associated with migraine. Major depressive disorder is both a risk factor for chronic migraine and a condition that one is more likely to develop after being diagnosed with chronic migraine. The study by de Vries Lentsch and colleagues investigated the use of two of the calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb) treatments — erenumab and fremanezumab — compared with a control group of patients with chronic migraine, with an eye on outcomes to measure depression. Of note, reduction in headache frequency (defined as reduction in monthly migraine days) was also investigated as an independent variable.

This was a single-center study performed at the University of Leiden Headache Center. It was not a randomized trial, but all patients were followed with an e-diary and Day 0 vs Day 90 questionnaires that tracked their headache frequency and severity as well as a number of metrics related to depression. Depressive symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS) and the Center for Epidemiological Studies Depression Scale (CES-D). The Headache Impact Test (HIT-6) was used to follow headache-related impact and disability, and the Perceived Stress Scale (PSS) was used to measure the degree of stressful situations the patient was experiencing.

The baseline depression scales between the three groups were 70%, 60%, and 66%, respectively; there were similar baseline levels of migraine frequency and disability as well. Both intervention groups showed a significant decrease in the symptoms of depression, and having a greater level of depression was negatively associated with reduction in monthly migraine days after 3 months. Of note, logistic-regression analysis determined that the reduction in depressive symptoms was independent of the reduction in migraine frequency.

Nearly all headache care providers are faced with challenging situations on a daily basis; often this is due to the comorbidity of mood disorders and high-frequency migraine. A traditional approach has been to provide the patient with a migraine preventive medication in the antidepressant family, such as a tricyclic antidepressant or serotonin and norepinephrine reuptake inhibitor (SNRI). Although these can be helpful, they are less specific for migraine prevention. Many patients are also already taking antidepressant medications, and the addition of a migraine-preventive antidepressant would be contraindicated. This study broadens the possibilities for prevention in these complicated patients and shows that there is benefit in both migraine-related outcomes and markers for depression when using CGRP-based therapy.

The way headache medicine is practiced changed dramatically in 2018 with the advent of CGRP monoclonal antibody (mAb) treatments for migraine. These medications have allowed us to target migraine specifically, whereas all of the preventive medications for migraine prior to 2018 were developed for other conditions and only secondarily helped migraine. These include the antidepressant, antihypertensive, and antiepileptic classes of medications, as well as onabotulinum toxin A, which, although approved for migraine, is not targeting a migraine-specific factor. Moskatel and colleagues sought to better understand the changing patterns of prescribing the nonspecific, or "traditional," migraine preventive medications in light of the advent of CGRP treatment.

This was a retrospective cohort study using aggregated data from the Stanford headache center. The percentage of patients with chronic migraine who had been prescribed one of the 10 most prescribed oral preventive medications or onabotulinum toxin A, or any of the four CGRP mAb, were calculated relative to the total number of patients with chronic migraine who received a prescription for any medication from the clinic during the pre-CGRP mAb years of 2015-2017 and post-approval years of 2019-2021.

The Stanford (STARR) database was filtered, searching for patients living in a California ZIP code with a diagnosis of chronic migraine who were followed from 2015 to 2021. The 10 most common non-CGRP preventive medications were amitriptyline/nortriptyline, valproate, duloxetine, gabapentin, memantine, propranolol, venlafaxine, verapamil, and onabotulinumtoxinA.

Erenumab was noted to initially be the most prescribed CGRP monoclonal antibody medication, but this was overtaken by galcanezumab after the second quarter of 2020 and throughout 2021. There is a statistically significant decrease in the percentage of patients receiving any of the non-CGRP preventive medications since 2018. The most significant decreases were in the tricyclic antidepressant class, as well as valproate, duloxetine, memantine, and onabotulinum toxin A. There was no statistically significant change in venlafaxine or gabapentin prescriptions.

This study highlights the changing face of headache medicine, and having a new class of migraine-specific treatment has significantly affected prescribing patterns. Although there is a statistically significant decrease in the prescribing of these non–migraine-specific preventive medications, they are still often recommended due to step-therapy regulations from insurance formularies, or as part of a polypharmacy regimen that may be more beneficial for a patient. These medications do improve patient outcomes and will remain a mainstay in migraine treatment.

Nearly all patients with migraine are recommended an acute medication to treat migraine attacks abortively; some patients are also recommended preventive therapies if migraine frequency significantly affects their quality of life. The American Headache Society/American Academy of Neurology guidelines for prevention recommend the initiation of a preventive medication at a frequency of 4-5 headache days per month or approximately 1 per week. Lipton and colleagues sought to determine whether there were any efficacy concerns in combining a CGRP mAb for prevention with ubrogepant, an oral CGRP antagonist, for acute treatment.

This was a prospective, open-level observational study assessing pain relief, return to normal function, and treatment satisfaction with patients given 50 or 100 mg of ubrogepant while concomitantly being given a seizure or mAb medication. Patients were allowed to be taking onabotulinumtoxinA as well as a CGRP mAb. The patients in this study were asked to track their headache symptoms using the Migraine Buddy e-diary. Meaningful pain relief was defined as a rating of migraine-related pain with one of the following choices 4 hours after taking the medication: no pain, mild pain, moderate pain, or severe pain. Return to normal function was defined as whether the patient determined they were able to function normally relative to their baseline at specific times post intervention. This was based on a functional disability scale. Treatment satisfaction was determined on the basis of a seven-point rating scale for how satisfied the patient felt with the medication at the end of the trial period.

A total of 245 participants provided at least 30 days of data, with 44.5% of the patients taking erenumab, 35.1% taking galcanezumab, 18.0% taking fremanezumab, and 2.9% taking eptinezumab. Meaningful pain relief was achieved by 61.6% of patients at 2 hours and 80.4% of patients at 4 hours post dose for both the 50-mg and 100-mg dose of ubrogepant. Return to normal function was achieved by 34.7% of patients at 2 hours and 50.5% at 4 hours post dose as well. Patients reported a 72.7% satisfaction level with the medication.

When CGRP acute medications were first approved, there was concern about the use of a mAb together with an oral antagonist. It was thought that CGRP medications would be associated with fewer benefits than when these medications were used alone, due to the belief that only a specific amount of CGRP could be blocked at any specific time. This trial shows that the efficacy of CGRP acute medications is not affected by concomitant use of mAb. Many patients who respond well to CGRP mAb will benefit significantly from the additional abortive use of oral antagonists.
