Head-to-Head Migraine Study Ends in Tie

By Pat Anson, PNN Editor

An unusual head-to-head competition between two migraine prevention drugs has ended in a virtual tie. There were no substantial differences in effectiveness between Emgality and Nurtec, according to preliminary results from a clinical trial released by Eli Lilly, the maker of Emgality.

Emgality and Nurtec both inhibit calcitonin gene-related peptides (CGRP), a protein that causes migraine pain, but their delivery systems are different. Emgality is injected once a month, while Nurtec is an oral medication taken every other day made by Biohaven Pharamceuticals, a subsidiary of Pfizer.

Eli Lilly launched the trial in late 2021, enrolling 575 participants in a Phase 4, double-blind, placebo-controlled study evaluating the efficacy and safety of Emgality (galcanezumab) and Nurtec (rimegepant) for 3 months in adults with episodic migraine.

The so-called CHALLENGE-MIG trial was a bold and somewhat risky move by Lilly, as it seeks to gain more market share in the highly competitive $2 billion U.S. migraine market.

In a statement, Lilly said Emgality did not meet the study's primary goal, which was statistical superiority to Nurtec in achieving at least a 50% reduction in monthly migraine headache days. The response rates of patients and safety profiles of both drugs were similar.

Lilly said Emgality was superior to Nurtec in some secondary outcomes, but didn’t disclose what they were. The company would only say that Emgality helped prevent migraines, as it has in previous studies.  

"These results bolster our knowledge of Emgality's ability to work quickly and help patients improve their quality of life with less frequent dosing," Anne White, executive vice president of Eli Lilly, said in a press release. "Reducing the frequency of migraine headache days can help people experience more freedom from the burden of this debilitating neurological disease and get back to participating in the daily activities that matter most to them."

Final result from the CHALLENGE-MIG trial won’t be posted until later this year.

“Nurtec ODT is the first and only medication approved as both an acute treatment for migraine and a preventive treatment for episodic migraine in adults. It offers flexibility to patients in treating their migraines and is the leading prescribed oral CGRP receptor antagonist,” Pfizer said in a statement. “We are confident in the efficacy and tolerability profile of Nurtec ODT as demonstrated in the clinical trials and the well-established patient preference for oral agents over injectables.

First approved by the FDA in 2018, CGRP inhibitors are the biggest innovation in migraine treatment in decades. They are also expensive, whether taken by pill or injection.

The listed cash price for Emgality is $679 for a single injection or $8,148 annually; while 8 tablets of Nurtec cost $1,011 or about $23,000 a year. Costs to patients will vary, depending on insurance coverage, copay assistance programs and rebates.

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 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.

‘Golden Era’ for Migraine Therapy Not Providing Relief

By Pat Anson, PNN Editor

In recent years there have been many advances in treating and preventing migraine – what some have called a “treatment revolution” in migraine therapy. New oral and injectable drugs block a key protein released during migraine attacks, and a novel smartphone-controlled device uses neuromodulation to help ease migraine pain.

But for many migraine sufferers, the increasingly crowded field in migraine therapy isn’t translating into pain relief or improved quality of life. Many are reluctant to seek treatment or take medication, and feel stigma about having the disease, according to two new studies.

“We are in a golden era for migraine care with the introduction of new therapeutic options for both the acute and preventive treatment of the disease, but if we don't address the need for better education, less stigma and improved access to care, we are falling short," said Eric Pearlman, MD, a senior medical director at Eli Lilly.

A survey released by the National Headache Foundation in recognition of Migraine and Headache Awareness Month found that less than a third (29%) of people with migraine feel that their disease is under control. The online survey of over 1,000 men and women diagnosed with migraine was funded by Biohaven Pharmaceutical.

Many respondents are concerned about side effects from the medications they take, such as brain fog, fatigue and sleepiness. Almost half of respondents (47%) between the ages of 18-59 say side effects have interfered with their ability to go to school or work. Nearly as many (46%) feel anxious about taking medication.

And despite the plethora of new choices available in migraine therapies, nearly two-thirds (65%) of migraine sufferers are still using an old medication -- triptans -- as a treatment for migraine pain.

"We must strive to understand and educate about the impact of this disease on not only physical well-being; but also, emotional and mental health," said Mary Franklin, executive director of National Headache Foundation. "Every person living with migraine has a different experience and we want all to feel confident in their treatment choices; but also know that there are others who understand the real impact of the disease."

The survey asked migraine sufferers about the emotional and mental burden of the disease, and the impact it has on daily life.

• 77% said they were not able to do the things they wanted to because of migraine attacks 

• 54% feared they were a burden to family, friends and colleagues

• 53% say they modified career plans due to migraine

• 42% were unable to exercise or engage in physical activity

• 37% feel less productive at work or school

• 28% feel less able to take care of their children

• 25% avoid sexual intimacy

The vast majority of respondents (93%) feel misunderstood and that those who don't suffer from migraine don't understand the severity of their disease.

OVERCOME Study

Results from the Biohaven survey were echoed in a large new study of more than 21,000 people living with migraine, which found that less than 30 percent are taking a recommended prescription medication.

"For millions of people living with migraine, the journey to an appropriate treatment program is fraught with gaps," said Susan Hutchinson, MD, scientific advisor to the OVERCOME study. "There are a variety of reasons at play, but it begins with the fact that many may not realize what they are experiencing is a migraine and not just 'another bad headache.'”

The OVERCOME (Observational Survey of the Epidemiology, Treatment and Care of Migraine) study was funded by Eli Lilly. It sought to assess the impact of new treatment options and whether migraine sufferers completed three critical steps in migraine management:

1. Actively sought care with a healthcare professional

2. Received a migraine diagnosis

3. Took a recommended prescription medication

Less than two-thirds (63%) of those who may benefit from acute migraine medication sought treatment from a healthcare provider. Of those, 75% were diagnosed with migraine. Among the diagnosed population, only 59% percent took a recommended drug. Overall, only 28 percent completed all three steps to appropriate care.

The results weren’t much better for OVERCOME respondents who may benefit from a migraine prevention drug. A little over two-thirds (69%) sought care and 79% received a migraine diagnosis. Of those who sought care and received a diagnosis, only 28% wound up taking a preventive medication for migraine. Overall, only 15 percent of this population completed all three steps to appropriate care.

Some migraine sufferers only seek treatment when their pain become unbearable. About 10% of respondents sought care in an emergency room or urgent care clinic setting, where they are less likely to receive an accurate diagnosis or take a recommended medication. 

"Even in light of recent new treatment options in the field of migraine, we still face an uphill battle as too many continue to be underserved," said Robert Shapiro, MD, a scientific advisor to the OVERCOME study. "An important aspect of migraine care that is truly diminished and may contribute to these findings is the stigma felt by many living with the disease. A person's reluctance to seek care or take medication for their migraine can be rooted in the fear of how a friend, employer, or even a loved one may view them for doing so."

Migraine affects about a billion people worldwide and 36 million adults in the United States, according to the American Migraine Foundation. In addition to headache pain, migraine can also cause nausea, vomiting, blurriness or visual disturbances, and sensitivity to light and sound. The World Health Organization classifies migraine as one of the 10 most disabling medical illnesses.
