Neuromodulation Device Effective for Most Migraine Sufferers

By Pat Anson, PNN Editor

A wearable neuromodulation device significantly reduced headache pain in nearly two-thirds of migraine sufferers, according to a new study. About one in four participants (22.6%) who used the device had no migraine pain after two hours.

The study findings, published in the journal Frontiers in Pain Research, are based on an analysis of over 23,000 remote electrical neuromodulation (REN) treatments with Nerivio, a device worn on the upper arm that uses mild electrical pulses to disrupt pain signals.

It’s important to note the study was designed and funded by Theranica Bio-Electronics, Nerivio’s manufacturer. Three of the five co-authors are Theranica employees.

“The current analysis of a very large group of patients, over a long period of time and multiple treatments, reinforces that REN provides a safe, efficacious and stable treatment option for acute treatment of migraine, both as a standalone and as an adjunct therapy. This is a very important component in the migraine therapy toolbox," lead author Jessica Ailani, MD, Director of the MedStar Georgetown Headache Center and Professor of Clinical Neurology, said in a press release.

Nerivio is controlled by a smartphone app that allows patients to set the intensity of their 45-minute treatments at the onset of a migraine. The app also has a migraine diary that allows patients and their doctors to track the effectiveness of REN.

It is from this app that study data was collected from 12,151 U.S. patients from 2019 to 2021. Most had been prescribed REN by headache specialists, indicating their migraines were difficult to treat with pain medication alone. During the study, about two-thirds of patients only used REN, with the remainder continuing to use over-the-counter or prescription medications.

"To the best of our knowledge, this study is the largest prospective real-world evidence analysis of a migraine device to date," said Alon Ironi, CEO of Theranica.

Migraine affects more than 37 million people in the United States, according to the American Migraine Foundation. In addition to headache pain, migraine can cause nausea, visual disturbances, and sensitivity to light and sound. Women are three times more likely to suffer from migraines than men.

Although migraine sufferers have many new treatments available, such as CBD oil and calcitonin gene-related peptide (CGRP) inhibitors, many find them too expensive or ineffective. Theranica hopes Nerivio can help fill the treatment gap, either as a standalone replacement for medication or as an adjunct.

"While some people with migraine get relief from prescribed or even over-the-counter medications, others do not respond to medications, or cannot tolerate their side effects. There are also people who cannot use medications due to contraindications or being at risk of drug-drug interactions or medication overuse headache,” Ailani said.

The FDA approved Nerivio as a treatment for acute migraine in adults in 2019. Last year the label was expanded to include children over the age of 12 with episodic or chronic migraine. Over 25,000 people in the U.S. have used the device, according to Theranica.

Nerivio is only available by prescription. When purchased wholesale, the listed price is $599 for a twelve-treatment unit, although buyers can save money by enrolling in a patient savings program, depending on their insurance coverage.  

Unusual Head-to-Head Migraine Study Pits Emgality vs. Nurtec

By Pat Anson, PNN Editor

Competition has grown intense between pharmaceutical companies in the $2 billion U.S. migraine market.

You’ve probably seen their TV commercials. Eli Lilly hired Olympic athletes to pitch Emgality, an injectable migraine preventative, while reality star Khloé Kardashian is appearing in commercials for Nurtec, an oral medication made by Biohaven Pharamceuticals

Lilly is now taking the competition a step further, with an unusual head-to-head clinical study – rare in the pharmaceutical industry – that pits Emgality against Nurtec. The company is enrolling 700 adults with episodic migraine in a randomized, double-blind, placebo-controlled trial. The so-called CHALLENGE-MIG study will directly compare the efficacy and safety of the two drugs.

“Lilly’s CHALLENGE-MIG study will help us understand how different types of preventive medications may help people achieve the goals that matter most to them. It’s exciting that insights generated in this first-of-its-kind head-to-head trial will be able to spark treatment plan discussions between people with migraine and their health care providers,” Shivang Joshi, MD, a trial investigator at Dent Neurologic Institute, said in a Lilly press release.

Emgality and Nurtec both inhibit calcitonin gene-related peptides (CGRP), a protein that causes migraine pain, but their delivery systems are very different. Emgality is injected once a month, while Nurtec is taken in a pill every other day.

Emgality was one of the first CGRP inhibitors to be approved by the FDA in 2018, while Nurtec is a relative newcomer, first approved in 2020. Nurtec’s label was recently expanded to include both migraine prevention and treatment.

The primary goal of the Lilly study is to see which drug gives patients a greater reduction in monthly headache days, with a secondary goal of measuring quality of life improvements.

“We believe patients should expect more and get more from medications that can help prevent migraine. Therefore, we look forward to sharing the findings from our Emgality versus Nurtec ODT head-to-head trial,” said Anne White, senior vice president of Eli Lilly and president of Lilly Neuroscience.

Biohaven’s CEO welcomes the study and sees it as an affirmation of Nurtec’s growing share of the market. Since it was introduced last year, Nurtec has generated about $200 million in revenue for Biohaven, with over 750,000 prescriptions filled. 

"This new head-to-head trial affirms that Nurtec ODT is perceived as the new standard of care.  The dual-therapy action of Nurtec ODT is unique and provides clear advantages to both treat and prevent migraine attacks.  Since the launch of oral acute CGRP agents, the performance of injectable CGRP (inhibitors) is now negligible to flat,” Vlad Coric, MD, CEO of Biohaven Pharmaceuticals, said in a statement to PNN. 

“Regardless of this Emgality study outcome, the Nurtec ODT value proposition will not be matched. And Nurtec ODT will have an impressive and entrenched market penetration by the completion of the proposed head-to-head study.  We continue to hear from patients, who want oral over needle-based therapies.” 

Regardless of whether it’s a pill or injection, both drugs are expensive. A supply of eight Nurtec tablets costs about $941, depending on insurance coverage. The listed price for Emgality is $627 for a single injection or about $7,524 annually.

FDA Approves Another Expensive Migraine Drug

By Pat Anson, PNN Editor

The highly competitive and lucrative market for migraine drugs will grow more crowded this month when AbbVie introduces Qulipta (atogepant), an oral CGRP medication developed for the prevention of episodic migraines.

The Food and Drug Administration approved Qulipta after seeing the results of a Phase 3 clinical trial that found the drug was 50 to 100% effective in preventing migraines.

"During the trial while taking Qulipta, I had many fewer migraine days. For the first time ever, I don't have difficulty doing my daily activities and I don't have to worry as much that a migraine attack will cause me to miss important events with family and friends," said Kelsi Owens, a trial participant who has lived with migraine for nearly three decades.

Like other CGRP inhibitors, Qulipta blocks proteins called calcitonin gene-related peptides from binding to nerve receptors in the brain and causing migraine pain. Since 2018, the FDA has approved over half a dozen CGRP medications, most of which are injected monthly.

Qulipta is a pill meant to be taken daily that comes in three different doses. Like other CGRP inhibitors, Qulipta is expensive. The wholesale price for a patient without insurance is $991 for 30 pills, according to Abbvie. Insured patients or those enrolled in an AbbVie patient support program will pay less.     

"Qulipta provides a simple oral treatment option specifically developed to prevent migraine attacks and target CGRP, which is believed to be crucially involved in migraine in many patients," said study investigator Peter Goadsby, MD, a neurologist and professor at University of California, Los Angeles. “I'm particularly encouraged by the convenience of the oral daily use of Qulipta, its rapid onset of significant efficacy, and its safety and tolerability as well as its high patient response rates.”   

Qulipta is expected to compete directly with Nurtec, an oral CGRP inhibitor made by Biohaven Pharmaceuticals that is approved for both migraine prevention and treatment. A supply of eight Nurtec tablets costs about $941, depending on insurance coverage. Since it was introduced in 2020, Nurtec has generated about $200 million in revenue for Biohaven, with over 750,000 prescriptions filled.

AbbVie says Qulipta will be available in early October. Wall Street analysts project Qulipta sales will reach $1 billion by 2030.

Side effects from Qulipta include nausea, constipation, fatigue and loss of appetite. AbbVie is currently conducting a clinical trial to seek if Qulipta should also be approved for the prevention of chronic migraine – patients who have 15 or more headaches per month.

Migraine affects more than 37 million people in the United States, according to the American Migraine Foundation. In addition to headache pain, migraine can cause nausea, visual disturbances, and sensitivity to light and sound. Women are three times more likely to suffer from migraines than men.

UK Migraine Sufferers Face ‘Broken Healthcare System’

By Pat Anson, PNN Editor

The United Kingdom has a “broken healthcare system” that leaves millions of migraine sufferers without treatment or a proper diagnosis, according to a new study.

The report by The Migraine Trust estimates that one in every seven people in the UK – about ten million -- suffer from migraine attacks. Most say they haven’t been officially diagnosed by a doctor and have never seen a headache specialist.

Those who have been diagnosed often have trouble getting a new class of drugs to prevent migraine -- calcitonin gene-related peptide (CGRP) inhibitors – even though the medications have been approved for use by the UK’s National Health Service (NHS).

“My migraine has never been managed properly by the NHS. I’ve suffered for 13 years and they’ve increasingly become worse each year. I’m bed bound at least once a week,” a migraine sufferer told the charity. “I visit my GP regularly and they send me away with a different drug to try for another year before I can be considered for another. I asked for a referral to the migraine clinic and was refused by my doctor.”

The Migraine Trust filed Freedom of Information requests with nearly a hundred NHS healthcare systems in England, Northern Ireland, Scotland and Wales and found that only a few were giving eligible patients access to CGRP treatment.

“There is clearly a postcode lottery of care where only the lucky few can access a treatment which has proven transformational for many migraine patients,” Rob Music, CEO of The Migraine Trust, said in a statement. “This should be such an exciting and positive time for those needing migraine care, but right now this lack of access is leading to continued poor health and deep frustration.” 

CGRP inhibitors have been available in the United States since 2018, including a drug recently approved for both migraine prevention and treatment. The medications – which block a protein released during migraine attacks from binding to nerve receptors in the brain – are not cheap. Eight tablets of Nurtec, for example, cost nearly $1,000. 

Not treating migraines can be costly as well. The Migraine Trust estimates that lack of adequate migraine treatment in the UK results in 16,500 emergency admissions and 43 million lost workdays every year.  

The charity says migraine attacks also have a negative impact on the lives of migraine sufferers. In surveys, nearly a third said migraines negatively affect their mental and physical health. About one in four said migraines disrupt their family and social life. 

The pandemic has also taken a toll on migraine patients, with 68% saying their symptoms have worsened. Some reported it was because of stress, some because their lifestyle was harder to manage, and others because they couldn’t access the treatment they had been receiving. An increase in computer screen time during the pandemic also contributed to worsening migraine attacks.    

The Migraine Trust recommends that everyone seeing a doctor for head pain should be assessed for migraine and receive an individualized care plan. More headache specialists and neurologists should also be recruited to bring the UK in line with other European nations. The Trust called for public awareness campaigns to improve understanding of migraine symptoms and reduce the stigma associated with migraine. 

About a billion people worldwide suffer from migraine headaches, which affect three times as many women as men. In addition to headache pain, migraine can cause nausea, blurriness or visual disturbances, and sensitivity to light and sound.

My Migraine Journey: From Electrodes to Cannabis

By Gabriella Kelly-Davies, PNN Columnist

The room swirled as my eyes fluttered open, and I could feel something tight around my neck. It felt like a vice, making it difficult to swallow. The antiseptic smell was familiar, but I couldn’t quite place it. Struggling to focus my eyes, I heard a voice I knew well — it was Ben, a doctor at the hospital where I worked as a physiotherapist.

“How do you feel?” Ben said, shining a bright torch into my eyes.

“Where am I?”

“You’re in emergency. An ambulance brought you here. You were lying on the side of the road, unconscious.”

Ben told me the ambulance officers had received reports of cyclists being pushed off their bikes at the quieter end of the beach. They assumed that’s what had happened to me.

That day, my twenty-fourth birthday, heralded the onset of a life of migraine attacks.

Gabriella Kelly-Davies

During the 1990s, I regularly traveled around Australia for work while studying business at night. In the plane as I read my textbooks, a pain like an electric shock would shoot up the back of my neck and head.

It lasted for several minutes, then a deep ache started in the base of my skull. The pain eventually spread upwards, fanning out until it covered the entire back of my head and temples.

All too soon, the pain I experienced while flying became more regular and was most severe after sailing and playing my piano or cello. Cycling and tennis also triggered it.

In 1996, I started a job in Parliament House, Canberra as a policy adviser to a senior politician. Mid-morning, I would feel shooting pains running up the back of my head, accompanied by waves of intense nausea. Soon afterwards, a deep ache in the base of my skull started, quickly spreading up over my head and into my temples. My eyes felt gritty, as if they were full of sand, and I yearned for them to explode to release the mounting pressure inside them.

Often when the pain was at its worst, I couldn’t think of the words I wanted to say, infuriating some colleagues. Sometimes I couldn’t string two words together coherently. My mouth refused to form the words I wanted to say, as if the messages weren’t getting through from my brain to the muscles in my face.

The Merry-Go-Round

Returning to Sydney in 1999, I despaired of ever being free of pain and nausea. I consulted an endless round of specialists and health professionals, but none of them helped much. I felt overwhelmed by head and neck pain and a general sense of ever-increasing pressure inside my head and eyes. I fantasized about boring a hole through the base of my skull with an electric drill to release the tension.

Between 2000 and 2005, I progressively stopped doing all the things I most loved because they triggered migraine attacks. My goal became getting through a day of work, returning home and lying in a dark room with a series of ice packs under my neck.

Anxiety about being stigmatized and the intolerance I perceived in some colleagues at work prevented me from admitting I was in pain. Instead, I worked like a Trojan to ensure I maintained a high level of performance and no one could accuse me of using pain as an excuse to under-perform.  

While on the endless merry-go-round of seeking solutions, I ended up at the Michael J. Cousins Pain Management and Research Centre in Sydney. Dr. Cousins and a team of health professionals assessed me. They diagnosed occipital neuralgia, a form of headache that can activate migraine attacks. I had chronic pain, a malfunction in the way the nervous system processes pain signals.

The team suggested an experimental treatment. It involved implanting tiny electrodes into the back of my head and neck to block the pain signals from traveling along the nerves in my head. I agreed to the surgery and afterwards; I had fewer migraine attacks than previously. I even had a few completely pain-free days.

One year later, I felt something sharp sticking out from the base of my skull. My pain specialist discovered an electrode wire protruding through the skin. Tests revealed the electrodes were infected, so they were removed. Afterwards, migraine attacks returned in full force.

Three months later, new electrodes were implanted, but they didn’t work as well, possibly because scar tissue blocked transmission of the electric current. Still, overall I was better than before the initial surgery. I worked full time and sang in a choir at Sydney Opera House.

Disappointingly, disaster struck in 2008. A superbug infected the electrodes, forcing my doctor to remove them. Once the infection cleared and the electrodes were re-implanted, they were only partially successful, and my life returned to its pre-electrode state.

Multidisciplinary Pain Management

A significant turning point occurred in 2009 when I participated in a three-week multidisciplinary pain management program. Each day, a team of pain specialists gave lectures on topics such as chronic pain and how it differs from acute pain. The physiotherapists started us on a carefully graded exercise program, and a psychologist taught us cognitive behavioural therapy techniques to help us change the way we thought about and dealt with pain. Surprisingly, the exercises didn’t cause a flare-up and at last I felt as if I was making progress.

The pain management program taught me to stop catastrophizing and to believe I had the power to change how I reacted to pain. For years, I practiced the stretches and strengthening exercises every night after work. I also applied the psychological techniques, and they became central to my daily routine.

Twelve years later, I continue to live with migraine. I’ve tried several migraine preventatives, but none helped. Eight months ago, I started taking medicinal cannabis and it has significantly reduced the frequency and severity of migraine attacks.

Over the years I’ve learned to reduce the impact of migraine on my life by using techniques such as mindfulness meditation and carefully paced exercise that turn down the volume of pain signals racing through my malfunctioning nervous system.

Chronic pain is complex and difficult to treat but it is possible to live well with pain. I encourage you to do a multidisciplinary pain management program and continue your search for approaches that reduce the impact of pain on your life.

A New Option for Young Migraine Sufferers

By Pat Anson, PNN Editor

Migraines can have a devastating impact on children and adolescents. In addition to causing head pain, upset stomachs and visual disturbances, migraine attacks can disrupt school and social activities at a sensitive time in a young person’s life.

Although pediatric migraines are common, affecting about 10% of school-age children and one in five teenagers, treatment options are very limited compared to adults. There are no FDA approved pharmaceutical migraine treatments for kids under the age of 12. That leaves doctors to prescribe migraine medication to children off-label, including a new class of migraine drugs called CGRP inhibitors, which have not yet been approved or studied in young children. 

A small new study suggests there may be a safer and more effective option for young migraineurs: neuromodulation. Research recently published in the journal of Pain Medicine found that Nerivio, a neuromodulation device worn on the upper arm, was more effective in treating acute migraine in adolescents than triptans and over-the-counter pain relievers. Nerivio uses smartphone-controlled electrical pulses to stimulate nerves and disrupt pain signals.

“To my knowledge, this is the first study that directly compared remote electrical neuromodulation and standard-care treatment options in adolescents,” says lead author Andrew Hershey, MD, co-director of the Headache Center at Cincinnati Children’s Hospital Medical Center.

“Migraine in adolescents is associated with poorer performance and absence from school and social activities during a particularly formative time in life. Providing teens with more effective and engaging treatments for migraine can have far-reaching positive effects over the course of their lives.”

Nerivio was developed by Theranica, an Israeli medical technology company that sponsored the study. The FDA approved the device as a treatment for acute migraine in adults in 2019 and recently expanded the label to include children over the age of 12 with episodic or chronic migraine.

THERANICA IMAGE

Thirty-five adolescent migraine patients aged 12 to 17 took part in the two-month comparison study. Over-the-counter drugs and oral triptans were used by patients during the medication month, and Nerivio during the Remote Electrical Neuromodulation (REN) month.

Two hours after treatment, over a third (37%) of patients achieved complete pain freedom during the REN phase of the study, compared to just 8.6% in the medication phase. Some degree of pain relief was reported by 80% of patients in the REN phase, as opposed to 57% in the medication phase.

“This study provides evidence that Nerivio may be considered as a first-line acute treatment, especially for adolescents with medication restricting comorbidities or a preference for a non-medication-based treatment,” said co-author Samantha Irwin, MD, a pediatric neurologist at the UCSF Benioff Children Hospital in San Francisco. “The importance of having a non-pharmacologic, discrete, easy-to-use and effective acute treatment in the adolescent armamentarium cannot be overstated.”

Long-Term Effects of Childhood Migraine

Early treatment of childhood migraine is important because there is emerging evidence that repeated headache attacks in children reduce the formation of “gray matter” in parts of the brain that process pain signals, leading to more frequent and severe migraines in adults.   

“We’ve done studies here independent of any pharmaceutical company where we’ve show that the earlier we can intervene with effective therapy and education of patients, the better their long-term outcome,” Hershey told PNN. “So we really have this opportunity to intervene with a child or adolescent that can affect them for their life.

“A device can be as effective as a drug. What I tell patients is that it gives them their own locus of control. Instead of taking a medication and hoping it works, they’re actually controlling the device with their smartphone, and so they can really take control of their headaches, which is ultimately what we want them to do.”    

Nerivio is only available by prescription and is eligible for insurance. When purchased wholesale, the listed price is $599 for a twelve-treatment unit, although buyers can save money by enrolling in a patient savings program, depending on their insurance coverage.  

Theranica is currently recruiting patients for a placebo-controlled study to see if Nerivio may be effective in preventing migraines. The company is also investigating whether the device may help treat other chronic pain conditions besides migraine.

Migraine affects more than 37 million people in the United States, according to the American Migraine Foundation. In addition to headache pain, migraine can cause nausea, blurriness or visual disturbances, and sensitivity to light and sound. Women are three times more likely to suffer from migraines than men.

Diet Changes Reduce Migraine Headaches

By Pat Anson, PNN Editor

There are many new treatments available for migraine sufferers; everything from CGRP inhibitors to neuromodulation to green light therapy. But there may be a simpler and less expensive way to reduce the frequency and severity of migraine headaches: changing your diet.

A new study funded by the National Institutes of Health found that migraine sufferers who ate more fatty fish and reduced their consumption of polyunsaturated vegetable oils had fewer headaches.

The findings are similar to another recent study that found foods containing healthy omega-3 fats – such as fish, flaxseed and walnuts – can reduce inflammation and neuropathic pain. Researchers say the two studies suggest that dietary changes can affect pain levels for other types of chronic pain.  

“It may ultimately be possible to integrate targeted dietary changes alongside medications to improve the lives of patients with chronic pain,” said Chris Ramsden, MD, a clinical investigator and adjunct faculty member at the University of North Carolina at Chapel Hill.

“Biochemical findings from both studies support the biological plausibility for this type of approach and could open the door to new approaches for managing many types of chronic pain. What is needed now is more evidence from randomized controlled trials in other populations with chronic pain.”

Ramsden is lead author of a study, published in the British Medical Journal, in which 182 adults with frequent migraines were broken into three groups and put on special diets for 16 weeks.

One group received meals that had high levels of fatty fish and low amounts of linoleic acid, a polyunsaturated fatty acid commonly found in American diets of corn, soybean and other vegetable oils. A second group received meals that had high levels of fatty fish and higher linoleic acid. The third control group received meals with high linoleic acid and low levels of fatty fish to mimic what an average American consumes.

"Our ancestors ate very different amounts and types of fats compared to our modern diets," said co-first author Daisy Zamora, PhD, an assistant psychiatry professor in the UNC School of Medicine. "Polyunsaturated fatty acids, which our bodies do not produce, have increased substantially in our diet due to the addition of oils such as corn, soybean and cottonseed to many processed foods like chips, crackers and granola."

When the study began, participants averaged over 16 headache days per month and over five hours of migraine pain each headache day -- despite taking multiple headache medications.

Those who consumed a diet low in vegetable oil and high in fatty fish had 30% to 40% reductions in total headache hours per day, severe headache hours per day, and overall headache days per month compared to the control group.

Blood samples from this group also had lower levels of pain-related omega-6 fatty acids found in processed foods.

“The effect we saw for the reduction of headaches is similar to what we see with some medications.”

— Daisy Zamora, PhD, UNC School of Medicine

“Our trial is the first moderate sized controlled trial showing that targeted changes in diet can decrease physical pain in humans,” Ramsden told PNN, noting that fatty acids appear to regulate the production of calcitonin gene-related peptides, the same protein targeted by CGRP medications.

“Diets alter the amounts of omega-3 and omega-6 fatty acids in the nervous system and other tissues linked to chronic pain. These fatty acids are converted by the body into biochemical mediators of pain. Several of these biochemical mediators act on receptor channels to regulate CGRP release,” he said in an email.

"I think this modification in diet could be impactful," Zamora added. "The effect we saw for the reduction of headaches is similar to what we see with some medications.”

Zamora, Ramsden and their colleagues are currently working on a new study to test diet modification for other chronic pain syndromes.

FDA Approves First Drug for Both Migraine Treatment and Prevention

By Pat Anson, PNN Editor

Migraine sufferers have a new medication that not only treats migraines, but can also be used to help prevent them. Biohaven Pharmaceuticals announced this week that Nurtec (rimegepant) -- a drug already being used to treat migraine pain – has been approved by the FDA as a migraine preventative, making it the first migraine medication that can be used for both treatment and prevention.

Nurtec is a calcitonin gene-related peptide (CGRP) inhibitor, a relatively new class of medication that blocks a protein released during migraine attacks from binding to nerve receptors in the brain. Since 2018, the FDA has approved a handful of CGRP medications, most which are taken by injection.

Nurtec is a quick-dissolving tablet that is taken orally. A single dose can treat migraine pain for up to 48 hours. The expanded FDA approval means Nurtec can now also be taken daily or every other day to help reduce the frequency of migraines. 

“The FDA approval of Nurtec ODT for the preventive treatment of migraine -- along with its acute treatment indication -- is one of the most groundbreaking things to happen to migraine treatment in my 40 years of practicing headache medicine. To have one medication patients can use to treat and prevent migraine will likely change the treatment paradigm for many of the millions of people who live with migraine," said Peter Goadsby, MD, a Professor of Neurology at the University of California, Los Angeles.

Goadsby was one of the investigators in a Phase 3 study that helped prove Nurtec can be used as a migraine preventive. In findings recently published in The Lancet, Nurtec reduced the number of migraine days per month by 30% after one week of treatment. After three months of treatment, about half of the patients taking Nurtec had at least a 50% reduction in the number of moderate-to-severe migraine days per month.

Nurtec was well-tolerated by most patients during the clinical trial. Some reported nausea, stomach pain and indigestion.

"This FDA approval marks the beginning of a new era for migraine treatments, allowing the potential for healthcare professionals to prescribe, and patients to have, a single medication to treat and prevent migraine attacks,” Biohaven CEO Vlad Coric, MD, said in a statement. “This groundbreaking approach to treating the full spectrum of migraine disease, from acute therapy to prevention, can have a significant impact in a patient's life by helping to decrease treatment plan complexity and reduce challenges with adherence and polypharmacy.”

One obstacle to using Nurtec is its cost. Currently, a single 75mg tablet is priced at about $117. A supply of eight tablets is around $941, depending on your insurance coverage and pharmacy.  Biohaven has a patient assistance program that can help some patients who lack insurance or can’t afford the drug.

A recent survey of nearly 4,700 migraine patients by Health Union found that about one in four (26%) are currently using a preventive CGRP medication. About 11 percent said they were using a CGRP to treat migraine pain. Patients who did not try the drugs said they were concerned about side effects, long-term safety and their cost.

Migraine affects more than 37 million people in the United States, according to the American Migraine Foundation. In addition to headache pain, migraine can cause nausea, blurriness or visual disturbances, and sensitivity to light and sound. Women are three times more likely to suffer from migraines than men.

A Virtual Headache on the Hill

By Mia Maysack, PNN Columnist

Last week I was fortunate to attend the 14th annual “Headache on the Hill,” a lobbying event held by the Alliance for Headache Disorders Advocacy (AHDA).  We had the largest turnout ever in participants and number of meetings, although it was a far different affair than previous ones.  

Due to the pandemic and Covid precautions, visits to congressional offices that normally would've taken place in person on Capitol Hill were conducted online via Zoom -- which was an adjustment I was grateful to make.

As a result of doing things virtually, it gave people who ordinarily may not be well enough to attend an opportunity to do so. I feel this is a more inclusive approach and should perhaps remain an option even after this pandemic settles. 

Traveling is extraordinarily strenuous on my health and always requires an extensive amount of recovery time. So the opportunity to lie down in between meetings and have the comforts of home around me -- such as soft lighting and blackout curtains -- made all the difference and helped make getting through the day possible. It also ensures I won't be confronted by weeks on end of flare ups and pain cycles. 

I am proud to represent the state of Wisconsin as a volunteer patient advocate, human rights activist and someone who has lived with intractable head pain to some extent each and every day for almost 21 years as a direct result of a traumatic brain injury.  

Given that there are around 40 million people in the U.S. alone who live with migraine disease, the odds are that you either experience it yourself or know of someone who does.  For those who are privileged not to have migraine, Covid-19 has given you a small taste of how we often exist:  shut in and unable to see loved ones, go to work or do things we enjoy. 

I live with both migraine disease and cluster headaches, which are called “suicide headaches” for good reason.  There's no limit to the chaos, interruption, inconvenience and discomfort these conditions have caused in my life, requiring my full time attention just to manage the symptoms.

The difficult experiences I and countless others have faced in seeking, finding and attempting different forms of treatment is why I continue to advocate -- even when I don't feel up to it. Migraine and other forms of head pain are at the top of the list regarding burden and disability, yet we've been severely limited with treatment options that usually mask the symptoms temporarily, as opposed to addressing the root cause.   

We've seen progress in recent years with more injectable treatment options, after being limited for decades to oral triptans. But insurance for the shots can be a nightmare (if you're fortunate enough to have insurance) and I received what was labeled as a "bad batch" of shots that gave me side effects I am still living with today.   

What We Asked For

Our medical system is set up in such a way that we’re able to receive a prescription relatively easily, but alternative tools such as water therapy, massage, oxygen and mindfulness meditation aren't seriously considered, let alone covered. This is a very real problem.

It also makes no sense that migraine conditions are some of the least funded research areas for the National Institutes of Health. Our “asks” during Headache on the Hill were to devote more funding toward the research and treatment of migraine. Currently there's only $20 million or so being spent. We’re requesting $50 Million designated specifically for NIH research on migraine and headache disorders.  

Additional funding could also help incentivize more providers to obtain neurology-related medical degrees, as there is a severe shortage and need for more headache specialists. More funding is needed to develop new treatments, help cultivate data on the benefits of more holistic approaches, and assist in providing more dignity to those of us who feel invisible and shunned by a system that's supposed to be on our side.  

Furthermore, and perhaps even more disgracefully, hundreds of thousands of our military veterans suffer from traumatic brain injuries as a result of being exposed to explosions and toxic open burn pits.  We asked for another $25 million to double the number of specialized treatment sites that the VA has for veterans with headache disorders. 

These are the individuals who ensure that we possess and maintain the liberties of this country and they deserve the absolute best we have to offer. I know that we can do better on all of these issues and we must. It's time to urge our representatives to follow through and do the right thing.

New European Guideline Says Opioids ‘Do Not Work’ for Many Types of Chronic Pain

By Pat Anson, PNN Editor

Calling opioid medication a “two edged sword,” the European Pain Federation (EFIC) has released new guidelines that strongly recommend against using opioids to treat fibromyalgia, low back pain, migraine, irritable bowel syndrome and other types of chronic non-cancer pain.

“The new recommendations advise that opioids should not be prescribed for people with chronic primary pain as they do not work for these patients,” the EFIC said in a statement.

However, the guideline states that low doses of opioids may be suitable for treating “secondary pain syndromes” caused by surgery, trauma, disease or nerve damage, but only after exercise, meditation and other non-pharmacological therapies are tried first.

“Opioids should neither be embraced as a cure‐all nor shunned as universally dangerous and inappropriate for chronic noncancer pain. They should only be used for some selected chronic noncancer pain syndromes if established non‐pharmacological and pharmacological treatment options have failed,” the guideline states. “In this context alone, opioid therapy can be a useful tool in achieving and maintaining an optimal level of pain control in some patients.”

Opioid pain relievers are not as widely used in Europe as they are in the United States or Canada. The EFIC said it was trying to “allay concerns over an opioid crisis” developing in Europe, as it has in North America.       

“As the leading pain science organisation in Europe, it is crucial that EFIC sets the agenda on issues such as opioids, where there are growing societal concerns. These recommendations clarify what role opioids should play in chronic pain management,” EFIC President Brona Fullen said in a statement.

The guideline’s lead author, Professor Winfried Häuser, said he and his colleagues tried to strike a middle ground on the use of opioids.

“The debate on opioid-prescribing for chronic non-cancer pain has become polarized: opioids are either seen as a dangerous risk for all patients, leading to addiction and deaths, or they are promoted as most potent pain killers for any type of pain,” said Häuser, who is an internal medicine specialist in Germany.

“Opioids are still important in the management of chronic non-cancer pain – but only in some selected chronic pain syndromes and only if established non-pharmacological and non-opioids analgesics have failed or are not tolerated.”

PROP Consulted for European Guideline

The guideline was developed by a 17-member task force composed of European experts in pain management, including 9 delegates selected by EFIC’s board “who advocate and who are critical with the use of opioids.” Only one delegate from Pain Alliance Europe represented patients.

The recommendations developed by the task force were reviewed by five outside experts, including Drs. Jane Ballantyne and Mark Sullivan, who belong to Physicians for Responsible Opioid Prescribing (PROP), an anti-opioid activist group in the U.S.  Ballantyne is PROP’s President, while Sullivan is a PROP board member. Several changes suggested by the outside experts were adopted.

Coincidentally, Ballantyne, Sullivan and three other PROP board members were involved in the drafting of the opioid guideline released in 2016 by the U.S. Centers for Disease Control and Prevention. That controversial guideline is now being rewritten by the CDC after voluminous complaints from patients and doctors that the recommendations led to forced tapering, withdrawal, uncontrolled pain and suicides.

Sullivan and two other PROP board members were also involved in drafting Canada’s 2017 opioid guideline, which was modeled after the CDC’s and provoked similar complaints from Canadian pain patients.

90 MME Recommended Limit

The CDC and Canadian opioid guidelines appear to have been used as resources by the EFIC task force, which adopted many of the same recommendations, even while acknowledging the low quality of evidence used to support them.   

One recommendation is straight out of the CDC guideline, advising European doctors to “start low and go slow.” Prescribers are urged to start patients on low doses of 50 morphine milligram equivalents (MME) or less a day and to avoid increasing the dosage above 90 MME/day.

One significant difference with the North American guidelines is that the EFIC recommends that opioids not be prescribed for fibromyalgia, migraines and other chronic “primary pain” conditions for which there is no known cause – suggesting those disorders have an emotional or psychological element that will lead to opioid abuse.

“Prescription of high doses of opioids to patients with primary pain syndromes might have been a factor driving the opioid crisis in North America,” the EFIC guideline warns.

“This was further compounded by patient characteristics that included physical and psychological trauma, social disadvantage and hopelessness that served as a trigger for reports of pain intensity prompting prescriptions of more opioids.”

Secondary pain conditions for which opioids “can be considered“ include multiple sclerosis, stroke, restless leg syndrome, Parkinson’s disease, rheumatoid arthritis, phantom limb pain, non-diabetic neuropathy, spinal cord injuries and Complex Regional Pain Syndrome (CRPS). 

Unlike the North American guidelines, the EFIC acknowledges that there are physical and genetic differences between patients. Some patients who are rapid metabolizers “might require higher dosages of opioids than the ones recommended by the guidelines.“

EFIC GRAPHIC

The EFIC also warns that its guideline should not be used to justify abruptly tapering or discontinuing opioids for anyone already prescribed at higher dosages. The recommendations are also not intended for the management of short-term acute pain, sickle cell disease or end-of-life care.

Medical Cannabis Linked to Rebound Headaches

By Pat Anson, PNN Editor

Medication overuse headache, also known as “rebound” headache, is a common problem for people who frequently use pain medication to relieve headaches and migraine.

According to the American Migraine Foundation, rebound headaches can be triggered by a wide assortment of analgesics, from aspirin and triptans to acetaminophen and opioids. Even caffeine can cause a rebound headache if you consume more than 200mg a day – about two cups of coffee.     

So perhaps it’s not surprising that medical cannabis is also associated with medication overuse headache, according to a preliminary study by researchers at Stanford University School of Medicine.

“Many people with chronic migraine are already self-medicating with cannabis, and there is some evidence that cannabis can help treat other types of chronic pain,” said study author Niushen Zhang, MD, a neurologist who is director of Stanford’s Headache Fellowship Program.

“However, we found that people who were using cannabis had significantly increased odds of also having medication overuse headache, or rebound headache, compared to people who were not using cannabis.”

Zhang and her colleagues looked at the medical records of 368 people who had chronic migraine -- which is 15 or more headache days per month. Less than half were using medical cannabis

Researchers found the cannabis users were six times more likely to have rebound headaches than those who did not use cannabis. People who used cannabis were also more likely to take opioids.  Previous research has found that opioids and cannabis can both influence the part of the brain called the periaqueductal gray, which has been linked to migraine.

Zhang’s study will be presented at the American Academy of Neurology’s annual meeting next month.

Medical cannabis has become a trendy alternative to pharmaceuticals for treating migraine, with research showing that both inhaled and ingested cannabis can reduce migraine pain. 

A recent study of nearly 10,000 people in the U.S. and Canada who used a migraine tracking app found that 82 percent who used cannabis believed it was an effective pain reliever.    

A 2017 study conducted in Israel found that combining THC and CBD in an oral dose was just as effective in treating migraine pain as amitriptyline – a tricyclic antidepressant commonly prescribed for migraine.

And a 2016 study at the University of Colorado found that cannabis significantly reduced the number of migraine headaches. Inhalation appeared to provide the fastest results, while edible cannabis took longer to provide pain relief.

About a billion people worldwide suffer from migraine headaches, which affect three times as many women as men. Over 37 million people in the United States live with migraines, according to the American Migraine Foundation.

Study Finds Regular Exercise Reduces Migraine Triggers

By Pat Anson, PNN Editor

Two-and-a-half hours of moderate to vigorous exercise a week can significantly reduce migraine triggers like stress, depression and poor sleep, according to a new survey that found more than two-thirds of migraine sufferers do not get enough exercise.

“Migraine is a disabling condition that affects millions of people in the United States, and yet regular exercise may be an effective way to reduce the frequency and intensity of some migraines,” says lead author Mason Dyess, DO, a Senior Fellow at the University of Washington School of Medicine.

“Exercise releases natural pain killers called endorphins, helps people sleep better and reduces stress. But if people with migraine are not exercising, they may not be reaping these benefits.”

The survey involved 4,647 people diagnosed with migraine. About three-fourths of participants had chronic migraine, meaning 15 or more migraines a month. The others had episodic migraine, or up to 14 a month.

Participants completed a questionnaire about their migraines, sleep, depression, stress, anxiety and the amount of exercise they get each week.

Researchers then divided them into five groups based on their level of exercise: those who did not exercise; people who exercised up to 30 minutes per week; those who exercised 31 to 90 minutes; people who exercised 91 to 150 minutes; and participants who exercised more than 150 minutes per week.

Types of exercise that qualified as moderate to vigorous included jogging, very brisk walking, playing a sport, heavy cleaning and bicycling.

Researchers found that only 1,270 participants – about 27 percent -- reported the highest level of exercise. Those who got less than 150 minutes of exercise had increased rates of depression, anxiety and sleep problems:

• Depression was reported by nearly half of people who got no exercise, compared to 25% of those that exercised the most.

• Anxiety was reported by 39% of people in the no exercise group, compared to 28% of people in the high exercise group.

• Sleep problems were reported by 77% of people in the no exercise group, compared to 61% in the high exercise group.

Researchers also found an association between exercise and increased frequency of migraines. Among people in the no exercise group, nearly half had 25 or more headache days per month. That compares to only 28% of people in the high exercise group.

“There are new therapeutics available for migraine, but they are very expensive. People with migraine should consider incorporating more exercise into their daily life because it may be a safe and low-cost way to manage and minimize some of the other problems that often accompany migraine,” said Dyess.

Two-and-a-half hours a week of moderate to vigorous exercise, or 150 minutes, is the minimum amount recommended by the World Health Organization.

The study findings, which will be presented at the annual meeting of the American Academy of Neurology in April, have not yet been peer-reviewed or published. One weakness of the study was that participants self-reported their exercise minutes, rather than having their activity monitored with a device. It also only shows an association between exercise and migraines, and does not prove cause and effect. 

Excedrin Brands Recalled Due to Faulty Packaging

By Pat Anson, PNN Editor

One of world’s most widely used over-the-counter pain relievers has turned into a real headache for GlaxoSmithKline (GSK).

The British pharmaceutical giant has recalled over 433,000 bottles of Excedrin because of holes found in bottles of five Excedrin brands: Excedrin Migraine Caplets, Excedrin Migraine Geltabs, Excedrin Extra Strength Caplets, Excedrin PM Headache Caplets and Excedrin Tension Headache Caplets.

There have been no reports of any injuries as a result of the faulty bottles, but GSK recalled them because of the risk of Excedrin tablets falling out and being swallowed by young children. Under U.S. federal law, the tablets must be sold in child resistant packaging.

“While the likelihood there are bottles on the market with holes is low, we are asking anyone who has purchased large-sized Excedrin (50 count and above) to check their Excedrin products and if there is a visible issue, contact GSK Consumer Relations at 1-800-468-7746 for a full refund. If your Excedrin bottle is not damaged, the product is safe to use as directed on the label,” GSK said in a statement.

“We take product safety very seriously at GSK and while we have not received any complaints or safety concerns to date on this potential problem, we are still letting consumers know so they can check their Excedrin bottles themselves. We sincerely apologize for any inconvenience, and please be assured we are working closely with the bottle manufacturer to fix this problem as quickly as we can.”

The bottles were sold at pharmacies, stores and online from March 2018 through September 2020. There was no explanation given for what caused the holes or why it took so long for GSK to recognize there was a problem and order a recall.

In January, GSK temporarily halted production of Excedrin Extra Strength and Excedrin Migraine due to “inconsistencies” in their ingredients. That led to spot shortages of the pain relievers.

In 2012, an Excedrin manufacturing plant in Nebraska was shut down for several months after Excedrin bottles were found to contain broken and stray tablets for other medications. At the time, the Excedrin brand was owned by Novartis.

An FDA investigation found that Novartis failed to adequately investigate hundreds of consumer complaints of foreign products found in over-the-counter drugs produced at the Nebraska plant. GSK now holds majority ownership of Excedrin through a joint venture with Novartis.

A recent study found GSK to be the most heavily fined drug company in the United States.  GSK paid nearly $9.8 billion to settle 27 cases brought against it for bribery, corruption, improper marketing, pricing violations and selling adulterated drugs.

Daily Drop of CBD Oil Reduces Migraine Headaches

By Pat Anson, PNN Editor

A CBD oil formulated for migraine sufferers significantly reduces the number of migraine headaches, according to a survey conducted by Axon Relief, a Utah-based company that makes a line of therapeutic CBD products.

“Our goal was to put out a CBD oil that is specific for people with migraine and to get feedback from them. There is a lot of anecdotal evidence that it works, but we haven’t seen any clinical data really behind it. And so this is kind of a first effort of ours to get some directional data on how effective this is,” says Ben Rollins, founder of Axon Relief.

Axon’s CBD Oil is made from pure hemp seed oil and has about 30mg of CBD per dose, a stronger than average dosage of cannabidiol. It contains no extra flavors, colors or THC (tetrahydrocannabinol), the psychoactive ingredient in cannabis, and is tested by a third-party lab.

The company asked new users of its CBD oil to take the Headache Impact Test (Hit-6™) both before and after a 30-day trial period. The questionnaire asks participants about the frequency and severity of their migraines, and how it impacts their daily lives.

Of the 105 customers who participated in the survey, 86 percent said a daily dose of the CBD oil reduced the impact of their headaches. On average, they also had nearly four fewer headache days per month.

The number of participants with chronic migraine – daily headaches – fell from 15 at the start of the study to 10 after the trial period, a 33% decline.

“Since the '90s I've been on constant high doses of carbamazepine and gabapentin. The periodic pain breakthroughs were only controlled by hydrocodone,” one user said. “What a change CBD Oil has made: no more carbamazepine or hydrocodone, and only half the gabapentin -- and far better pain control.”

Another participant said the CBD oil “significantly helped with my chronic migraines. If taken at onset, I can rely on it to take the edge off relatively quickly."

Previous studies have found that inhaled and ingested cannabis help reduce migraine pain.  A recent study of nearly 10,000 people in the U.S. and Canada who used a migraine tracking app found that 82 percent who used cannabis believed it was an effective pain reliever.    

A 2017 study conducted in Israel found that combining THC and CBD in a 200mg oral dose reduced pain by 55 percent in a small group of migraine sufferers.

And a 2016 study at the University of Colorado found that inhaled and ingested cannabis significantly reduced the number of migraine headaches. Inhalation appeared to provide the fastest results, while edible cannabis took longer to provide pain relief.

Axon Relief will soon be introducing an extra strength version of its CBD oil, which will contain about 100mg of CBD per dose. The company is also releasing a new dietary supplement in capsule form that combines CBD with magnesium, CoQ10 and riboflavin – ingredients recommended by the Migraine Trust. 

Survey Finds Patients Wary of Trying CGRP Migraine Drugs

By Pat Anson, PNN Editor

Khloe Kardashian and Serena Williams have their work cut out for them. Despite their endorsement of a new type of migraine medication, many patients remain wary of the drugs and few have tried them, according to a large new survey.

The annual survey of nearly 4,700 migraine patients by Health Union found that about one in four (26%) are currently using a preventive CGRP medication, down from 29% in last year’s survey. And only 11 percent of patients said they were using a CGRP to treat migraine pain.

CGRP stands for calcitonin gene-related peptides, a protein that binds to nerve receptors in the brain and triggers migraine pain. Since 2018, the FDA has approved four injectable CGRP inhibitors (Aimovig, Ajovy, Emgality, Vyepti) to prevent migraine and two CGRP tablets for acute migraine (Ubrelvy, Nurtec). The latter two were recently endorsed by reality star Kardashian and tennis star Williams.   

Although Eli Lilly, Teva, Amgen, and other drug companies have aggressively marketed CGRP medications and even given the drugs away for free to get people to try them, sales growth has been slow. Only Aimovig and Emgality are used by at least 10 percent of migraine patients.

PERCENTAGE OF PATIENTS CURRENTLY USING CGRP INHIBITORS

SOURCE: HEALTH UNION 'MIGRAINE IN AMERICA 2020'

Most migraine patients continue to rely on older and cheaper medications such as triptans, anti-depressants, anti-convulsants, over-the-counter drugs, and Botox injections.

The Health Union survey helps explain why. While most patients are aware of CGRP inhibitors and nearly half (43%) had tried a preventive CGRP, most stopped taking them after trying just one brand. That’s not uncommon for migraine sufferers, who often have try multiple treatments before finding one that works.   

“Everybody’s experience with treatment is different. And the fact that there are multiple brands available is actually a really good thing. Because some of them just happen to work better for some people than others,” says Brian Green, Health Union’s vice-president of community business solutions.

CGRP’s do work for some patients. The Health Union survey found that 58% of patients currently using a preventive CGRP reported having less head pain. And nearly half said they didn’t react as strongly to migraine triggers such as loud noises and bright light.  

Those who had heard of preventive CGRP medications but had not tried them cited a number of reasons:

• 44% Doctor has not recommended it

• 27% Concerned about side effects

• 21% Concerned about long-term safety

• 19% Can’t afford them

• 14% Insurance won’t cover

CGRP medications are not cheap. Eight doses of Nurtec, the acute CGRP endorsed by Kardashian, can cost over $1,000 without insurance.

Nearly half the patients surveyed said they were still using triptans or over-the-counter pain medication for migraine relief. Antidepressants and Topamax were the most commonly used medications for migraine prevention. 

Migraine affects more than 37 million people in the United States, according to the American Migraine Foundation. In addition to headache pain, migraine can cause nausea, blurriness or visual disturbances, and sensitivity to light and sound. Women are three times more likely to suffer from migraines than men.
