Migraine ICYMI

SAN DIEGO — In the phase 3 ALLEVIATE study, eptinezumab (Vyepti, Lundbeck) failed to achieve a statistically significant improvement in the primary outcome of reducing the number of weekly attacks from week 1 to week 2 in patients with episodic cluster headache. However, the drug met secondary outcomes of reduction in weekly attacks, mean change in baseline pain, and Patient Global Impression of Change (PGIC) score.

Eptinezumab is the latest of multiple anti–calcitonin gene-related peptide (CGRP) therapies to fail in the clinic against episodic cluster headache, all using weekly attacks as a primary endpoint, though therapies also scored positive results for secondary endpoints, according to Stewart Tepper, MD, who presented the study results at the annual meeting of the American Headache Society

Eptinezumab is already approved for migraine, and is fully bioavailable by the end of an infusion. “That was why we thought this might be a really interesting treatment for prevention of cluster headache,” said Dr. Tepper, who is VP of external research at the New England Institute for Neurology and Headache in Stamford, Connecticut.
 

Are We Looking at the Wrong Endpoint?

Secondary endpoints offered more encouragement. “For each week, the eptinezumab looked either numerically higher than the placebo or nominal statistical significance was achieved. By week 4, two-thirds of the patients had at least a 50% reduction in their number of weekly cluster attacks. Then the average pain intensity for the day and the patient global impression of change were all in favor of eptinezumab. That made us interested in whether we’re missing something, whether this is maybe not the correct endpoint to be looking at,” said Dr. Tepper.

He suggested that it may be time for the Food and Drug Administration (FDA) to reconsider the endpoints used in clinical trials for cluster headaches.

Study criteria included cluster periods that lasted at least 6 weeks, and at least 1 year since the diagnosis of episodic cluster headache. The study enrolled patients who were out of their cluster period, who underwent a second screening of 7-14 days after they entered a new cycle. After that, they were randomized to an injection of placebo or 400 mg eptinezumab, and followed for 4 weeks. After 4 weeks, all patients received an injection of 400 mg eptinezumab and placebo patients were crossed over to eptinezumab and followed out to 24 weeks.

The study population included 231 patients (78% male; mean age, 44 years), with a mean of 2.7 cluster headache attacks per day an average duration of 62 minutes per attack. The worst pain was reported as excruciating in 59% of participants.

The mean change in number of weekly attacks in weeks 1 and 2, compared with baseline, was not statistically significant (–4.6 with eptinezumab, –4.6 with placebo; P = .5048). More patients in the eptinezumab group had a 50% or greater reduction in attack frequency in weeks 3 (50.9% vs 37.3%; P < .05), week 3 (62.5% vs 43.8%; P < .01), and week 4 (66.7% vs 50.5%; P < .01). The difference in mean change in pain from baseline became statistically significant at week 3 and 4 (P < .01). There were also statistically significant differences in PGIC score at weeks 1, 2, and 4. The frequency of any treatment-emergent adverse event was similar in the eptinezumab and placebo groups (25.0% vs 26.5%), and only one led to treatment withdrawal in the eptinezumab group (0.9%).
 

Thoughts on Redesigning Cluster Headache Clinical Trials

During the Q&A session, Andrea Harriott, MD, PhD, a neurologist at Massachusetts General Hospital, Boston, and the session’s moderator, asked Dr. Tepper for his thoughts on how to design a good cluster headache trial. “I think we should go to the regulators and say we’re looking at the wrong outcome measure, and that we should use responder rate as the primary endpoint. That’s my guess. I think after four failed cluster studies for anti-CGRP therapies in terms of primary endpoint, all of which suggest some benefit, I think maybe we are looking at the wrong endpoint,” said Dr. Tepper.

Dr. Tepper was also asked about the potential for comparative efficacy trials testing anti-CGRP versus usual therapy, or usual therapy combined with antibodies against usual therapy. He noted that he had coauthored a recent commentary that responded to International Headache Society 2022 guidelines for randomized, placebo-controlled trials in cluster headache. “We actually did suggest comparative effectiveness [trials], both for recruitment and for compassion, but one of the problems is that verapamil is not even FDA approved for cluster headache in the US, and galcanezumab (Emgality, Eli Lilly) [is not approved] in the EU, so it becomes difficult from a regulatory standpoint to set that up, and you have to have buy in from regulatory authorities,” said Dr. Tepper.

Dr. Tepper has financial relationships with many pharmaceutical companies, including consulting for/advising Lundbeck, which funded the study. Dr. Harriott has served on the scientific advisory board of Theranica and has an authorship agreement with AbbVie.

SAN DIEGO – Researchers are unraveling the complex relationship between cardiovascular (CV)- and stroke-related outcomes in migraine with, and without, aura.

Early results of one study suggest that aura increases the risk for major adverse cerebrovascular and CV events (MACE) in those with migraine, and that this risk is particularly high in men.

“We confirmed that aura increases the risk for these cerebrovascular and cardiovascular outcomes in people with migraine and that there’s an increased risk of these MACE events in men with migraine,” said study investigator Gina Dumkrieger, PhD, principal data science analyst and assistant professor of neurology, Mayo Clinic, Phoenix, Arizona.

The findings were presented at the annual meeting of the American Headache Society.
 

Few Data on Migraine and Stroke Risk

The extent to which migraine increases the risk for stroke CV outcomes has not been extensively studied.

“We’re trying to find out whether migraine-related factors make it more likely that you’re going to have one of these events,” said Dr. Dumkrieger. “Knowing a particular factor increases the risk is something patients and medical providers would want to know.”

Using Mayo Clinic electronic health records, which cover all three sites (Florida, Minnesota, and Arizona), researchers identified individuals with migraine using diagnostic codes. They also looked at data on sex, race, and the presence of aura.

They investigated whether a history of MACE risk factors — including atrial fibrillation, diabetes, hyperlipidemia, hypertension, and tobacco use — affected risk and the potential interaction of aura with these risk factors.

MACE events included cerebral infarction, intracerebral hemorrhage, and acute myocardial infarction.

The analysis included 130,126 participants (80% women, 95% White individuals). Of these, 6% experienced a MACE event, and 94% did not.

“We confirmed that aura does increase the risk for a MACE event, and all of the known risk factors that we included were also significant,” said Dr. Dumkrieger.

Odds ratios (ORs) were 3.82 for atrial fibrillation, 3.11 for hypertension, and 3.06 for hyperlipidemia.

It was surprising, said Dr. Dumkrieger, that male sex was tied to an increased risk for a MACE event (OR, 1.40). “This is not something that was known before,” she said.

The link between migraine and ischemic stroke, particularly with aura, was stronger in women — particularly young women.

Investigators also found an interaction between male sex and aura, when it comes to MACE outcomes, said Dr. Dumkrieger. “Males in general are at higher risk, and people with aura are at higher risk. Males with aura are also at higher risk, but maybe not as much as you would think they would be. It’s not a purely additive thing. This is something we need to look into more,” she said. 

The study also revealed an interaction between aura and hypertension as well as aura and tobacco use, but here too, it was not an additive risk, said Dr. Dumkrieger. However, she added, the presence of aura does not moderate the risk for hyperlipidemia, diabetes, or atrial fibrillation.

The research also showed a significant interaction between male sex and Black race which was additive. “There’s apparently increased risk if you are male and Black or African American that’s greater than what you would expect. We should be especially concerned about these individuals,” she said.
 

Unanswered Questions

The current analysis is part of a larger study that will more closely examine these relationships. “We want to learn, for example, why aura moderates some of the risk factors but not others,” said Dr. Dumkrieger.

The researchers also plan to investigate other migraine features, including headache frequency, and headache sensations such as pulsating or throbbing.

Dr. Dumkrieger was an investigator of another study, also presented at the AHS meeting, that’s investigating the role of migraine-specific features and imaging results in the complex interrelationship between migraine and MACE risk.

That study, which also used the Mayo Clinic electronic health record data, included 60,454 migraine patients diagnosed with migraine after 2010.

Researchers divided participants into those with a MACE outcome (1107) and those without such an outcome (59,347) after at least 2 years of follow-up. They created a propensity cohort of individuals matched for age and risk factors for MACE outcome.

The final cohort consisted of 575 patients with and 652 patients without MACE outcome.

One of the most interesting early results from this study was that those with a MACE outcome had significantly more white matter hyperintensities than those with no MACE outcome, at 64% versus 51%, respectively. 

This and other findings need to be validated in a different cohort with an electronic health records database from another institution. In future, the team plans to focus on identifying specific migraine features and medications and their relative contributions to MACE risk in migraine patients.

Yet another study featured at the AHS meeting confirmed the increased risk for stroke among migraine patients using a large database with over 410,000 subjects.

Results showed stroke was more than three times more common in those with a migraine diagnosis than in those without (risk ratio, [RR] 3.23; P < .001). The RR for hemorrhagic stroke (3.15) was comparable with that of ischemic stroke (3.20).

The overall stroke RR for chronic migraine versus controls without migraine was 3.68 (P < .001). The RR for migraine with aura versus migraine without aura was 1.37 (P < .001).
 

Useful Data

Commenting on the research, Juliana VanderPluym, MD, a headache specialist at the Mayo Clinic, Phoenix, Arizona, described this new information as “very useful.”

The fact that there are more white matter lesions on MRI scans in migraine patients with MACE needs further exploration, said Dr. VanderPluym.

“Understanding how much of that relates to migraine, how much relates to other comorbid conditions, and what this all means together, is very important, particularly because MACE can be life-threatening and life-altering,” she added.

Learning how migraine medications may impact MACE risk is also something that needs to be examined in greater depth, she said. “I would think that migraines that are controlled might have a different risk for MACE than uncontrolled migraine,” she said.

The investigators reported no relevant financial conflicts of interest.

SAN DIEGO — In a bid to address the severe shortage of headache neurologists across the United States, the American Headache Society (AHS) has developed a program aimed at primary care physicians (PCPs) to help address the unmet demand for headache treatment and management.

It is estimated that about 4 million PCP office visits annually are headache related, and that 52.8% of all migraine encounters occur in primary care settings.

However, PCPs aren’t always adequately trained in headache management and referral times to specialist care can be lengthy.

Data published in Headache show only 564 accredited headache specialists practice in the United States, but at least 3700 headache specialists are needed to treat those affected by migraine, with even more needed to address other disabling headache types such as tension-type headache and cluster headache. To keep up with population growth, it is estimated that the United States will require 4500 headache specialists by 2040.
 

First Contact

To tackle this specialist shortfall, the AHS developed the First Contact program with the aim of improving headache education in primary care and help alleviate at least some of the demand for specialist care.

The national program was rolled out in 2020 and 2021. The educational symposia were delivered to PCPs at multiple locations across the country. The initiative also included a comprehensive website with numerous support resources.

After participating in the initiative, attendees were surveyed about the value of the program, and the results were subsequently analyzed and presented at the annual meeting of the American Headache Society.

The analysis included 636 survey respondents, a 38% response rate. Almost all participants (96%) were MDs and DOs. The remainder included nurse practitioners, physician assistants, and dentists.

About 85.6% of respondents reported being completely or very confident in their ability to recognize and accurately diagnose headache disorders, and 81.3% said they were completely or very confident in their ability to create tailored treatment plans.

Just over 90% of participants reported they would implement practice changes as a result of the program. The most commonly cited change was the use of diagnostic tools such as the three-question Migraine ID screener, followed closely by consideration of prescribing triptans and reducing the use of unnecessary neuroimaging.

“Overall, there was a positive response to this type of educational programming and interest in ongoing education in addressing headache disorders with both pharmaceutical and non-pharmaceutical treatment options,” said Nisha Malhotra, MD, a resident at New York University (NYU) Langone Health, New York City, who presented the findings at the conference.

The fact that so many general practitioners were keen to use this easy-to-use screen [Migraine ID screener], which can pick up about 90% of people with migraine, is “great,” said study investigator Mia Minen, MD, associate professor and chief of headache research at NYU Langone Health. “I’m pleased primary care providers said they were considering implementing this simple tool.”

However, respondents also cited barriers to change. These included cost constraints (48.9%), insurance reimbursement issues (48.6%), and lack of time (45.3%). Dr. Malhotra noted these concerns are primarily related to workflow rather than knowledge gaps or lack of training.

“This is exciting in that there doesn’t seem to be an issue with education primarily but rather with the logistical issues that exist in the workflow in a primary care setting,” said Dr. Malhotra.

Participants also noted the need for other improvements. For example, they expressed interest in differentiating migraine from other headache types and having a better understanding of how and when to refer to specialists, said Dr. Malhotra.

These practitioners also want to know more about treatment options beyond first-line medications. “They were interested in understanding more advanced medication treatment options beyond just the typical triptan,” said Dr. Malhotra.

In addition, they want to become more skilled in non-pharmaceutical options such as occipital nerve blocks and in massage, acupuncture, and other complementary forms of migraine management, she said.

The study may be vulnerable to sampling bias as survey participants had just attended an educational symposium on headaches. “They were already, to some degree, interested in improving their knowledge on headache,” said Dr. Malhotra.

Another study limitation was that researchers didn’t conduct a pre-survey analysis to determine changes as a result of the symposia. And as the survey was conducted so close to the symposium, “it’s difficult to draw conclusions on the long-term effects,” she added.

“That being said, First Contact is one of the first national initiatives for primary care education, and thus far, it has been very well received.”

The next step is to continue expanding the program and to create a First Contact for women and First Contact for pediatrics, said Dr. Minen.
 

Improved Diagnosis, Better Care

Commenting on the initiative, Juliana VanderPluym, MD, a headache specialist at the Mayo Clinic, Phoenix, who co-chaired the session where the survey results were presented, said it helps address the supply-demand imbalance in headache healthcare.

“Many, many people have headache disorders, and very few people are technically headache specialists, so we have to rely on our colleagues in primary care to help address the great need that’s out there for patients with headache disorders.”

Too many patients don’t get a proper diagnosis or appropriate treatment, said Dr. VanderPluym, so as time passes, “diseases can become more chronic and more refractory, and it affects people’s quality of life and productivity.”

The First Contact program, she said, helps increase providers’ comfort and confidence that they are providing the best patient care possible and lead to a reduction in the need for specialist referrals.

Dr. Minen serves on the First Contact advisory board.

SAN DIEGO — Migraine may be associated with a greater risk of cardiovascular disease, ischemic stroke, and transient ischemic attack (TIA), but also a reduction in risk of hemorrhagic stroke in men, according to results from a retrospective analysis of Veterans Health Administration (VHA) data. Migraine was also linked to greater risk of cardiovascular disease, and the researchers found similar risk among both genders, with the exceptions of a larger stroke risk among women and larger risk of TIA among men.

Gender Matters

The research complements other studies, such as an analysis drawn from the Women’s Health Study, according to Alexandra Schwartz, a doctoral student at Yeshiva University, who presented the research at the annual meeting of the American Headache Society. That study found a 53% increased risk of stroke (hazard ratio [HR], 1.53; 95% confidence interval [CI], 1.02-2.31) among 17,531 female subjects between the ages of 25 and 42. Another, smaller study in 1,400 men drawn from the Physicians Health study found an increased risk of major cardiovascular events of 1.24 (P = .008). Previous studies have shown that around two-thirds of VHA patients with migraine are male. “Our population gives us this really unique opportunity to look at men with migraine,” Ms. Schwartz said in an interview.

The differential risk factors among men and women are tantalizing. “Gender likely matters in terms of how migraine and stroke are related, and a number of other cardiovascular diseases,” said Ms. Schwartz.

Migraine has long been considered a disease of women, but 6% of men experience the condition, making it important to understand how migraine might affect cardiovascular result in men. “We would expect that there could be different underlying mechanisms in this kind of relationship ... it is absolutely worth understanding the extent to which this disease might impact their risk of cardiovascular events,” senior author Elizabeth Seng, PhD, said in an interview. She is a professor at Yeshiva University and a research associate at Albert Einstein School of Medicine.

The researchers examined data from 2,006,905 veterans between 2008 and 2021, including 681,784 migraineurs (492,234 men; 189,430 women) and 1,325,121 controls (983,154 men; 341,967 women) that were matched based on age within a 5-year band, gender, race, ethnicity, and VHA site of care.

Among individuals diagnosed with migraine, there was an increased risk of ischemic stroke (odds ratio [OR], 2.7; 95% CI, 2.6-2.7), TIA (OR, 7.3; 95% CI, 6.8-7.7), cardiovascular disease (OR, 3.6; 95% CI, 3.5-3.6), acute myocardial infarction (OR, 1.7; 95% CI, 1.6-1.8), heart failure (OR, 1.3; 95% CI, 1.3-1.4), and unstable angina (OR, 2.7; 95% CI, 2.5-2.8). There was an association between migraine and a lower risk of hemorrhagic stroke (OR, 0.4; 95% CI, 0.4-0.5), but only in men. When the findings were analyzed by gender, the findings were generally similar with the exception of a statistically significant, larger risk of ischemic stroke in women (OR, 3.0 versus 2.6), and a trend toward greater risk of TIA in men (OR, 7.3 versus 6.5).

While the study lends unique insight due to the high proportion of men, it also comes with the limitation that the participants were veterans, and may therefore differ from the general population with respect to general health status and other characteristics, said Ms. Schwartz.
 

Another Piece of the Puzzle

The large number of men in the study is important, according to session moderator Laine Green, MD, who was asked for comment. “The biggest population that was studied with respect to cardiovascular risk was the Women’s Health Study, which was predominantly White nurses over time, and it is one of our biggest important pieces of information when it comes to cardiovascular risk, specifically looking at those with migraine who seem to have this doubling of their underlying stroke risk. Trying to get the same type of information from different populations is exquisitely helpful, because it’s long been thought that the risk for stroke and cardiovascular events seems to lie with females with aura. Knowing that there may be risk in other groups is important and part of the overall counseling that we do with patients,” said Dr. Green, assistant professor of neurology at Mayo Clinic Arizona.

The findings could hint at causal mechanisms, according to Dr. Seng. Preliminary analyses, not yet reported, suggest that age also plays a role in the relationship between migraine and cardiovascular risks. “I think that it’s important to [determine] to what extent migraine might back up the curve on the age-related timing of these events. Migraine peaks in the 40s, and that’s well before most of these cardiovascular events peak. We want to understand not just the cross-sectional relationships, which were large, but also the extent to which migraine may be having a differential impact on risk in different age bands,” said Dr. Seng.

Ms. Schwartz, Dr. Seng, and Dr. Green have no relevant financial disclosures.

SAN DIEGO — A new analysis of patients with new daily persistent headache (NDPH) lends insight into the condition and provides some hints as to some of the more effective treatments, including some calcitonin gene-related peptide (CGRP) inhibitors.

“There’s just not a lot [of information] about these patients,” Mark Burish, MD, PhD, associate professor of neurology at UT Houston, said in an interview. He presented the results of the survey at the annual meeting of the American Headache Society.

There have been some retrospective analyses of patient data, but that has a lot of potential for bias. “It’s only the patients who can afford to be there, and who needed those treatments, and so we want to do more of a general survey,” said Dr. Burish.

The results weren’t particularly surprising, and tended to reaffirm what was known anecdotally, including symptoms similar to those of migraine, but it gave some insight into treatments. “Some of the CGRP inhibitors and the onabotulinum toxin seem to be some of the more effective treatments, according to our survey, so those are probably worth looking into for these patients if you can get them approved by insurance, and if you can get patients to accept the idea they might have to give themselves an injection of some sort,” said Dr. Burish.

Despite having some promise, there was variation among CGRP inhibitors. Eptinezumab, rimegepant, and atogepant were commonly reported as effective, but others, such as erenumab and galcanezumab, were less often reported. “None of them were incredibly effective. These were just the best things we have at this time,” said Dr. Burish.
 

Additional Information on a Rare, Hard-to-Treat Condition

Jason Sico, MD, who moderated the session, was asked for comment. “I’m so appreciative that the team has looked at a new daily persistent headache. It’s a rare type of headache disorder. It’s also one that is notoriously difficult to treat and something that we that we really need to know more about. It is difficult to really get good, robust in-depth information on these patients, and the team did a really nice job with that,” said Dr. Sico, associate professor of neurology and internal medicine at Yale School of Medicine and national director of the Headache Centers of Excellence Program within the Veterans Health Administration.

He noted that the researchers found that opioids were the most commonly used acute treatment. That’s not surprising, but “it would be interesting to see what was tried before someone had gotten to opioids,” he said.

The findings also gave some unexpected insight into the condition. “I really found it striking that an overwhelming majority of patients reported brain fog. Given the context that it is daily persistent headache, one could surmise that they have brain fog a lot of the time,” said Dr. Sico.
 

‘A Good Data Set’

The researchers analyzed data from 337 international patients who responded to a survey. They also randomly selected 34 patients for an interview, and 32 of those were deemed likely to have NDPH. “So we really spent some effort making sure this was a good data set,” said Dr. Burish. The participant population was 72% female, 83.7% White, and 70.7% were based in the United States, though other countries included Canada, the United Kingdom, Australia, Ireland, Germany, Sweden, and Switzerland. The mean age was 41.2 years. The peak ages of onset were between 11 and 40 years, though there were a few cases in the 0-5 age range and over 70. Possible triggers that occurred in the 3 months before onset included psychological stressors (34%), infection or inflammation (32%, COVID infection (5%), injury or surgery (8%), or a change in medications (4%). No clear trigger was identified by 22% of respondents.

The survey included information on associated features, and frequently reported issues included brain fog (approximate 75%), sound sensitivity (about 62%), light sensitivity (57%), nausea (39%), smell sensitivity (32%), visual disturbances (28%), vomiting (13%), and chills (9%).
 

Insights Into Treatment Efficacy

Dr. Burish showed a slide of responses to questions about acute treatments that respondents had tried at least once and viewed as ‘completely effective,’ ‘mostly effective,’ or ‘somewhat effective.’

“No medicine was completely effective, which I think a lot of people know from NDPH. It is notoriously difficult to treat. The things on the top of the list are mostly opioids. There’s one (non-opioid), the DHE (dihydroergotamine) injection. All the way on the other side, you have diphenhydramine. The NSAIDs and triptans are mostly in the middle. We did ask about some of the wearable devices, and we had extra questions about, are you using it appropriately? Those are kind of in the middle or towards the bottom [in frequency],” said Dr. Burish.

There was a similar question regarding effective preventive medications that had been tried for at least 2 months or 3 months in the cause of onabotulinum toxin or CGRP medications. “This one had a little bit more of a pattern to it: A lot of the CGRP medications are up toward the top. It’s not perfect. Erenumab and galcanezumab are closer to the bottom, but it was interesting that a lot of the CGRP medicines were toward the top. Onabotulinum toxin was also somewhat toward the top. We looked at a few different anti-inflammatories. Methylprednisolone is kind of toward the upper half at least, whereas prednisone and montelukast are at the absolute bottom. And the prednisone is a pretty good dose, 50 milligrams or higher. There are some people thinking that this is an inflammation or infectious etiology, (but) it wasn’t that all of the anti-inflammatories were necessarily toward the top of the list,” said Dr. Burish.

Dr. Burish has received funding from Lundbeck. Dr. Sico has no relevant financial disclosures.

SAN DIEGO — A new analysis of patients with new daily persistent headache (NDPH) lends insight into the condition and provides some hints as to some of the more effective treatments, including some calcitonin gene-related peptide (CGRP) inhibitors.

“There’s just not a lot [of information] about these patients,” Mark Burish, MD, PhD, associate professor of neurology at UT Houston, said in an interview. He presented the results of the survey at the annual meeting of the American Headache Society.

There have been some retrospective analyses of patient data, but that has a lot of potential for bias. “It’s only the patients who can afford to be there, and who needed those treatments, and so we want to do more of a general survey,” said Dr. Burish.

The results weren’t particularly surprising, and tended to reaffirm what was known anecdotally, including symptoms similar to those of migraine, but it gave some insight into treatments. “Some of the CGRP inhibitors and the onabotulinum toxin seem to be some of the more effective treatments, according to our survey, so those are probably worth looking into for these patients if you can get them approved by insurance, and if you can get patients to accept the idea they might have to give themselves an injection of some sort,” said Dr. Burish.

Despite having some promise, there was variation among CGRP inhibitors. Eptinezumab, rimegepant, and atogepant were commonly reported as effective, but others, such as erenumab and galcanezumab, were less often reported. “None of them were incredibly effective. These were just the best things we have at this time,” said Dr. Burish.

Jason Sico, MD, who moderated the session, was asked for comment. “I’m so appreciative that the team has looked at a new daily persistent headache. It’s a rare type of headache disorder.

It is difficult to really get good, robust in-depth information on these patients, and the team did a really nice job with that,” said Dr. Sico, associate professor of neurology and internal medicine at Yale School of Medicine and national director of the Headache Centers of Excellence Program within the Veterans Health Administration.

Medications classified as anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAb), a relatively new category of migraine therapy, have shown strong evidence of efficacy for migraine treatment and prevention. However, as these medications — which include Aimovig (erenumab), Emgality (galcanezumab), Ajovy (fremanezumab), and Vyepti (eptinezumab) — are new, their long-term outcomes are not known; in addition, they are expensive and they do not work for everyone. Patients who are doing relatively well on other medications might ask about switching to one of the anti-CGRP mAb so that they can experience the better outcomes and low side-effect profile that they've been hearing about. New research is showing some prognostic indicators that can help identify which patients might experience a better response to anti-CGRP mAb.

A prospective real-world study published in the May 2024 issue of Journal of Neurology, Neurosurgery, and Psychiatry included 5818 patients who had been treated with an anti-CGRP mAb for high-frequency episodic or chronic migraine. The researchers assessed responses after 6 months of use, defining a good response as ≥50% reduction in monthly headache days and excellent response as ≥75% reduction in monthly headache days. They found that several pretreatment baseline factors were predictors of a good or excellent 6-month response: older age, the presence of unilateral pain, the absence of depression, fewer monthly migraine days, and lower Migraine Disability Assessment (MIDAS) score. Notably, men and women experienced comparable outcomes. While it's not completely clear why these factors were associated with better responses to anti-CGRP mAb, the results could help in selecting patients who might or might not benefit from this new medication class.

Results of a prospective study published in the May 2024 in The Journal of Headache and Pain demonstrated that patients treated with eptinezumab for 3 months experienced a reduction of monthly headaches, migraines, and the use of acute medication. The patients who had previously had an inadequate response to or were unable to tolerate other anti-CGRP mAb (erenumab, galcanezumab, fremanezumab) were less likely to experience improvement with eptinezumab than patients who had not had previous unsuccessful attempts with anti-CGRP mAb. This suggests that it might not be beneficial for patents to try multiple medications in this category if they have had an inadequate response or intolerability to others in the same drug class.

Lifestyle factors can play a role in migraine outcomes and may reduce the need for medication. A study published in The Journal of Headache and Pain in May 2024 examined the relationship between migraine and the American Heart Association (AHA) Guidelines for Cardiovascular Health recommended lifestyle factors. The study included 332,895 participants, with a median follow-up of 13.58 years. Researchers found that maintaining targeted or recommended body mass index (BMI), physical activity, sleep duration, sleep pattern, and sedentary time were associated with substantial reductions in migraine risk.

Diet, another lifestyle factor, can also have an effect on migraine. Avoiding dietary triggers is a well-known adjustment that many patients are advised to make. Overall diet quality can play a role in migraine outcomes as well. According to a study published in the May 2024 issue of Nutritional Neuroscience, participants who followed a diet that qualified as having a high Carbohydrate Quality Index (CQI) had lower migraine severity and duration than participants whose diets did not qualify as high CQI. The study included 266 women (age 18-45 years), using a 147-item food frequency questionnaire to assess CQI. The CQI, a relatively new index for measuring carbohydrate quality, includes four components: glycemic index, dietary fiber intake, ratio of whole grain to total grain, ratio of solid carbohydrates to total (solid + liquid) carbohydrates.¹ A low glycemic index and higher scores for the other three factors translates to a high CQI.

While the results of the AHA/migraine study and the CQI/migraine study are interesting, the physiologic reasons for the outcomes and validation of the results need further investigation. It's not clear whether the decrease in migraines that's associated with optimal carbohydrate intake is associated with outcomes such as low BMI or better sleep, or whether carbohydrate metabolism could be an independent factor.

Predictive factors can be beneficial in making migraine treatment decisions. While trial and error will always remain part of optimal migraine therapy, customizing treatment on the basis of an individual patient's characteristics can help in reaching an effective treatment and better quality of life sooner.

SAN DIEGO — Nearly one in three patients with migraine are reluctant to seek medical help and many blame healthcare providers, results of a recent survey showed.

Participants cited concerns that their complaints would be dismissed, a belief that healthcare providers could offer no additional help, and a prior unsuccessful clinician visit as reasons for not seeking care. Survey respondents saw an average of four clinicians before finally receiving a diagnosis.

“I was shocked that a third of patients were reluctant to seek care,” said study investigator Elizabeth K. Seng, PhD, associate professor, Ferkauf Graduate School of Psychology, Yeshiva University, and research associate professor, department of neurology, Albert Einstein College of Medicine, both in New York City. “That just shows a much higher level of medical distress than I expected from this community of people who are obviously suffering from this significant neurologic disease.”

The findings were presented at the annual meeting of the American Headache Society.
 

‘Significant Disease’

The study included 500 adults with migraine (mean age, 40 years) who signed up for a patient support group sponsored by Eli Lilly and completed a comprehensive survey. Respondents were mostly female, White, non-Hispanic, and well-educated individuals.

Half of participants had episodic migraines, and half had chronic migraines; 46% reported experiencing anxiety and 33% reported depression.

Almost all respondents had initiated treatment with a first calcitonin gene-related peptide (CGRP) monoclonal antibody.

“These are people who have significant enough disease that eventually they needed our top-tier preventive medication,” Dr. Seng said.

Participants answered a variety of questions pertaining to disease factors and treatment seeking. Just over 70% said they suspected they had migraine prior to diagnosis, “which means for almost 30%, it was a surprise when they received the diagnosis,” said Dr. Seng. 

Nearly 40% reported that a relative first suggested they may have migraine, and 33% suspected it themselves. Only 17.4% said a healthcare provider suggested they may have the condition.

Almost a third of respondents (30.5%) reported they were reluctant to seek medical help.

“Some said they didn’t think their physician could do anything more than they were already doing for themselves, or that they’d be taken seriously, or they had had talked to doctors before and this wasn’t helpful,” said Dr. Seng. 

These responses speak to the need for better public health messaging, she said. “People have this idea that migraine attacks aren’t a big deal when, in fact, these attacks area big deal and certainly deserve treatment.” 

Family and friends were participants’ most common source of information on migraine, followed by the Internet. “This highlights the importance of getting migraine-related information out there so that when people talk to their friends and family, they’re receiving accurate information,” said Dr. Seng.

When asked about the path to a diagnosis, respondents reported consulting an average of four providers before receiving an accurate diagnosis. “That’s pretty remarkable,” Dr. Seng said.

An increase in frequency or severity of migraine attacks or attacks that interfered with work or school “pushed people over the threshold to seek care,” Dr. Seng said. 

A subset of patients was asked about the factors they believed could help with migraine attacks. Of these, 80% cited diet and 70% stress reduction. Supplements, exercise, and relaxation techniques were cited much less frequently, said Dr. Seng. 

The mean age of respondents’ migraine diagnosis was 26 years, so there was about 18 years from the time of diagnosis to participation in the survey, which could introduce recall bias. Other potential limitations included the fact that the survey had no open-ended questions, and men and ethnic minorities were underrepresented. 
 

Useful Data

Commenting on the study findings, Nina Riggins, MD, PhD, president, Brain Performance Center and Research Institute, and director of the Headache Center at The Neuron Clinic, San Diego, California, said the survey findings are “very useful” and highlight “significant opportunities for improvement in migraine education for clinicians and people living with migraine disease.”

The fact that participants reported consulting an average of four healthcare providers before receiving an accurate diagnosis underscores the importance of providing clinicians with tools to identify migraine, she said.

This is especially relevant as new migraine therapies that may improve efficacy and have fewer side effects become available, she added. 

“It would be interesting to see in future studies if migraine recognition by non-headache specialists improved after CGRP-blocking medications for migraine management became available,” said Dr. Riggins, who is cochair of the AHS First Contact program which is aimed at improving headache management in primary care.

She added that she and her colleagues will keep these survey results in mind when creating future educational materials for clinicians.

The study was supported by Eli Lily. Dr. Seng is a consultant for GlaxoSmithKline, Theranica, and Abbvie, and receives research support from the National Institutes of Health, National Center for Complementary and Integrative Health, National Institute of Neurological Disorders and Stroke, Veterans Health Administration, Cystic Fibrosis Foundation, and the American Heart Association. Dr. Riggins reported no relevant conflicts.

Survey respondents saw an average of four clinicians before finally receiving a diagnosis.

“I was shocked that a third of patients were reluctant to seek care,” said study investigator Elizabeth K. Seng, PhD, associate professor, Ferkauf Graduate School of Psychology, Yeshiva University, and research associate professor, department of neurology, Albert Einstein College of Medicine, both in New York City. “That just shows a much higher level of medical distress than I expected from this community of people who are obviously suffering from this significant neurologic disease.”

The findings were presented at the annual meeting of the American Headache Society.
 

‘Significant Disease’

The study included 500 adults with migraine (mean age, 40 years) who signed up for a patient support group sponsored by Eli Lilly and completed a comprehensive survey. Respondents were mostly female, White, non-Hispanic, and well-educated individuals.

Half of participants had episodic migraines, and half had chronic migraines; 46% reported experiencing anxiety and 33% reported depression.

Almost all respondents had initiated treatment with a first calcitonin gene-related peptide (CGRP) monoclonal antibody.

“These are people who have significant enough disease that eventually they needed our top-tier preventive medication,” Dr. Seng said.

Participants answered a variety of questions pertaining to disease factors and treatment seeking. Just over 70% said they suspected they had migraine prior to diagnosis, “which means for almost 30%, it was a surprise when they received the diagnosis,” said Dr. Seng. 

Nearly 40% reported that a relative first suggested they may have migraine, and 33% suspected it themselves. Only 17.4% said a healthcare provider suggested they may have the condition.

Almost a third of respondents (30.5%) reported they were reluctant to seek medical help.

“Some said they didn’t think their physician could do anything more than they were already doing for themselves, or that they’d be taken seriously, or they had had talked to doctors before and this wasn’t helpful,” said Dr. Seng. 

These responses speak to the need for better public health messaging, she said. “People have this idea that migraine attacks aren’t a big deal when, in fact, these attacks area big deal and certainly deserve treatment.” 

Family and friends were participants’ most common source of information on migraine, followed by the Internet. “This highlights the importance of getting migraine-related information out there so that when people talk to their friends and family, they’re receiving accurate information,” said Dr. Seng.

When asked about the path to a diagnosis, respondents reported consulting an average of four providers before receiving an accurate diagnosis. “That’s pretty remarkable,” Dr. Seng said.

An increase in frequency or severity of migraine attacks or attacks that interfered with work or school “pushed people over the threshold to seek care,” Dr. Seng said. 

A subset of patients was asked about the factors they believed could help with migraine attacks. Of these, 80% cited diet and 70% stress reduction. Supplements, exercise, and relaxation techniques were cited much less frequently, said Dr. Seng. 

The mean age of respondents’ migraine diagnosis was 26 years, so there was about 18 years from the time of diagnosis to participation in the survey, which could introduce recall bias. Other potential limitations included the fact that the survey had no open-ended questions, and men and ethnic minorities were underrepresented. 
 

Useful Data

Commenting on the study findings, Nina Riggins, MD, PhD, president, Brain Performance Center and Research Institute, and director of the Headache Center at The Neuron Clinic, San Diego, California, said the survey findings are “very useful” and highlight “significant opportunities for improvement in migraine education for clinicians and people living with migraine disease.”

The fact that participants reported consulting an average of four healthcare providers before receiving an accurate diagnosis underscores the importance of providing clinicians with tools to identify migraine, she said.

This is especially relevant as new migraine therapies that may improve efficacy and have fewer side effects become available, she added. 

“It would be interesting to see in future studies if migraine recognition by non-headache specialists improved after CGRP-blocking medications for migraine management became available,” said Dr. Riggins, who is cochair of the AHS First Contact program which is aimed at improving headache management in primary care.

She added that she and her colleagues will keep these survey results in mind when creating future educational materials for clinicians.

The study was supported by Eli Lily. Dr. Seng is a consultant for GlaxoSmithKline, Theranica, and Abbvie, and receives research support from the National Institutes of Health, National Center for Complementary and Integrative Health, National Institute of Neurological Disorders and Stroke, Veterans Health Administration, Cystic Fibrosis Foundation, and the American Heart Association. Dr. Riggins reported no relevant conflicts.

SAN DIEGO — In a randomized, controlled trial, lidocaine injections to the greater occipital nerve were effective in controlling migraine symptoms among adolescents. The treatment has long been used in adults, and frequently in children on the strength of observational evidence.

Prior Research

Most of the studies have been conducted in adults, and these were often in specific settings like the emergency department for status migrainosus, while outpatient studies were generally conducted in chronic migraine, according to presenting author Christina Szperka, MD. “The assumptions were a little bit different,” Dr. Szperka, director of the pediatric headache program at Children’s Hospital of Philadelphia, said in an interview.

Retrospective studies are also fraught with bias. “We’ve tried to look at retrospective data. People don’t necessarily report how they’re doing unless they come back, and so you lose a huge portion of kids,” said Dr. Szperka, who presented the research at the annual meeting of the American Headache Society.

“From a clinical perspective, I think it gives us additional evidence that what we’re doing makes a difference, and I think that will help us in terms of insurance coverage, because that’s really been a major barrier,” said Dr. Szperka.

The study also opens other avenues for research. “Just doing the greater occipital nerves only reduces the pain so much. So what’s the next step? Do I study additional injections? Do I do a study where I compare different medications?”

She previously conducted a study of how providers were using lidocaine injections, and “there was a large amount of variability, both in terms of what nerves are being injected, what medications they were using, the patient population, et cetera,” said Dr. Szperka. Previous observational studies have suggested efficacy in pediatric populations for transition and prevention of migraine, new daily persistent headache, posttraumatic headache, and post-shunt occipital neuralgia.
 

A Randomized, Controlled Trial

In the new study, 58 adolescents aged 7 to 21 (mean age, 16.0 years; 44 female) were initially treated with lidocaine cream. The patients were “relatively refractory,” said Dr. Szperka, with 25 having received intravenous medications and 6 having been inpatients. After 30 minutes, if they still had pain and consented to further treatment, Dr. Szperka performed bilateral greater occipital nerve injections with lidocaine or a saline placebo, and did additional injections after 30 minutes if there wasn’t sufficient improvement.

There was no significant change in pain after the lidocaine cream treatment, and all patients proceeded to be randomized to lidocaine or placebo injections. The primary outcome of 30-minute reduction in pain score ranked 0-10 favored the lidocaine group (2.3 vs 1.1; P = .013). There was a 2-point reduction in pain scores in 69% of the lidocaine group and 34% of the saline group (P = .009) and a higher frequency of pain relief from moderate/severe to no pain or mild (52% versus 24%; P = .03). There was no significant difference in pain freedom.

After 24 hours, the treatment group was more likely to experience pain relief from moderate/severe to no pain or mild (24% vs 3%; P = .05) and to be free from associated symptoms (48% vs 21%; P = .027). Pain at the injection site was significantly higher in the placebo group (5.4 vs 3.2), prompting a change in plans for future trials. “I don’t think I would do saline again, because I think it hurt them, and I don’t want to cause them harm,” said Dr. Szperka.

Adverse events were common, with all but one patient in the study experiencing at least one. “I think this is a couple of things: One, kids don’t like needles in their head. Nerve blocks hurt. And so it was not surprising in some ways that we had a very high rate of adverse events. We also consented them, and that had a long wait period, and there’s a lot of anxiety in the room. However, most of the adverse events were mild,” said Dr. Szperka.
 

Important Research in an Understudied Population

Laine Greene, MD, who moderated the session, was asked for comment. “I think it’s an important study. Occipital nerve blocks have been used for a long period of time in management of migraine and other headache disorders. The quality of the evidence has always been brought into question, especially from payers, but also a very important aspect to this is that a lot of clinical trials over time have not specifically been done in children or adolescents, so any work that is done in that age category is significantly helpful to advancing therapeutics,” said Dr. Greene, associate professor of neurology at Mayo Clinic Arizona.

Dr. Szperka has consulted for AbbVie and Teva, and serves on data safety and monitoring boards for Eli Lilly and Upsher-Smith. She has been a principal investigator in trials sponsored by Abbvie, Amgen, Biohaven/Pfizer, Teva, and Theranica. Dr. Greene has no relevant financial disclosures.

SAN DIEGO — Susceptibility to post-traumatic headache could be linked to mutations in ion channel and ion transporter genes, according to results from a preliminary study.

Post-traumatic headache is a common symptom of traumatic brain injury (TBI).

There is evidence that genetic mutations could play a role in both TBI development and response. In particular, the S213L mutation for familial hemiplegic migraine-1 (FHM1), found in the CACNA1A gene, can cause individuals carrying it to be highly sensitive to otherwise trivial head impacts, according to Lyn Griffiths, PhD.

The consequences can be post-traumatic headache, but also seizures, cerebral edema, coma, or worse. Another form of FHM is associated with mutations in ATP1A2.

“This stimulated our interest in looking at genes that relate to TBI with a particular focus on ion channel genes,” said Dr. Griffiths, during a presentation of the study at the annual meeting of the American Headache Society.

The researchers analyzed data from 117 participants who had at least one concussion with a post-traumatic headache, and recruited family members when possible. There were 15 participants who developed severe reactions to trivial head trauma, 13 who had been diagnosed with concussion and underwent imaging related to TBI-associated symptoms, 54 who had been recruited through local sporting groups campuses, and 35 recruited through a medical research foundation. Blood or saliva samples were used to perform whole exome sequencing.

The researchers looked for gene candidates within different tiers. Tier 1 included genes that had already been implicated in severe migraine. The second tier included 353 ion channel and iron transporter genes. Tier 3 comprised neurotransmission-related genes.

After sequencing, the researchers filtered genetic mutations to include only those that affected amino acid composition of the protein, were predicted by two or more in silico analysis tools to be damaging, and were identified in multiple, unrelated patients.

In tier 2, the greatest number of potential damaging variants were found in the SCN9A gene, which is involved in pain perception and processing. There were six variants found in eight cases. Of these eight individuals, three had suffered severe reactions to relatively minor head trauma.

In tier 3, the researchers identified mutations in eight neurotransmitter-related genes.

Through comparison with a general population control group, the researchers identified 43 different rare, amino acid–changing variants that occurred within 16 ion channel and ion channel transporter genes. These mutations were found in 53 individuals, at an approximately fivefold higher frequency than the control group (odds ratio, 5.6; P < .0001).

“We identified a number of rare genetic variants implicated in migraine — ion channel and other neurologically associated genes — in those suffering from post-traumatic headache,” said Dr. Griffiths. She also noted that the whole genomes they collected will allow for further analysis of other gene candidates in the future.

During the Q&A period, Dr. Griffiths was asked if the research group tracked the severity of the TBIs suffered by participants. She responded that they had not, and this was a limitation of the study.

Another questioner asked if parents should consider genetic testing for susceptibility mutations when considering whether to allow a child to participate in sports or activities with elevated risk of TBI. “I don’t necessarily think this is a bad thing,” she said, though she conceded that the work is still immature. “It’s probably a bit early because we haven’t identified all the genes that are involved or all the specific mutations ... but I think down the track, that makes perfect sense. Why would you not do some sensible preventive screening to aid with things like maybe you wear more headgear or you consider what’s the appropriate sport for that person?”

Laine Green, MD, assistant professor of neurology at Mayo Clinic Arizona, Phoenix, who moderated the session, was asked for comment. “I think the idea of potentially identifying people that have more genetic susceptibility to injuries is very intriguing, because post-traumatic headache and symptoms is always a difficult area to treat, potentially identifying those that with more genetic susceptibility might be helpful. It may also potentially allow us to target specific treatments, especially in this case, looking at different ion channels. There are medications that may work better at ion channel targets than other targets,” said Dr. Green.

He also endorsed the potential value of screening. “Speaking as a parent, I might like to know my child is at higher risk if they’re going to participate in contact sports or other high risk activities,” he said.

In tier 2, the greatest number of potential damaging variants were found in the SCN9A gene, which is involved in pain perception and processing. There were six variants found in eight cases. Of these eight individuals, three had suffered severe reactions to relatively minor head trauma.

In tier 3, the researchers identified mutations in eight neurotransmitter-related genes.

Through comparison with a general population control group, the researchers identified 43 different rare, amino acid–changing variants that occurred within 16 ion channel and ion channel transporter genes. These mutations were found in 53 individuals, at an approximately fivefold higher frequency than the control group (odds ratio, 5.6; P < .0001).

“We identified a number of rare genetic variants implicated in migraine — ion channel and other neurologically associated genes — in those suffering from post-traumatic headache,” said Dr. Griffiths. She also noted that the whole genomes they collected will allow for further analysis of other gene candidates in the future.

During the Q&A period, Dr. Griffiths was asked if the research group tracked the severity of the TBIs suffered by participants. She responded that they had not, and this was a limitation of the study.

Another questioner asked if parents should consider genetic testing for susceptibility mutations when considering whether to allow a child to participate in sports or activities with elevated risk of TBI. “I don’t necessarily think this is a bad thing,” she said, though she conceded that the work is still immature. “It’s probably a bit early because we haven’t identified all the genes that are involved or all the specific mutations ... but I think down the track, that makes perfect sense. Why would you not do some sensible preventive screening to aid with things like maybe you wear more headgear or you consider what’s the appropriate sport for that person?”

Laine Green, MD, assistant professor of neurology at Mayo Clinic Arizona, Phoenix, who moderated the session, was asked for comment. “I think the idea of potentially identifying people that have more genetic susceptibility to injuries is very intriguing, because post-traumatic headache and symptoms is always a difficult area to treat, potentially identifying those that with more genetic susceptibility might be helpful. It may also potentially allow us to target specific treatments, especially in this case, looking at different ion channels. There are medications that may work better at ion channel targets than other targets,” said Dr. Green.

He also endorsed the potential value of screening. “Speaking as a parent, I might like to know my child is at higher risk if they’re going to participate in contact sports or other high risk activities,” he said.

Key clinical point: High adherence to the carbohydrate quality index (CQI) was associated with a significant reduction in headache severity and duration in women with migraine.

Major finding: High CQI adherence was associated with low odds of moderate pain (adjusted odds ratio [aOR] 0.37; P = .01), severe pain (aOR 0.22; P = .001), and prolonged headache duration (aOR 0.54; P = .03). Moreover, there was no significant correlation between CQI and migraine disability assessment scores (P > .05).

Study details: This cross-sectional study assessed the association of CQI with headache severity, disability, and duration in 266 women with migraine using a 147-item semiquantitative food frequency questionnaire.

Disclosures: The authors did not disclose any source of funding. The authors declared no conflicts of interest.
