Headache & Migraine

Here are the stories our MDedge editors across specialties think you need to know about today:

First reported U.S. case of COVID-19 linked to Guillain-Barré syndrome

The first official U.S. case of Guillain-Barré syndrome (GBS) associated with COVID-19 has been reported by neurologists from Allegheny General Hospital in Pittsburgh, further supporting a link between the virus and neurologic complications, including GBS.

Physicians in China reported the first case that initially presented as acute GBS. Subsequently, physicians in Italy reported five cases of GBS in association with COVID-19.

“This onset is similar to a case report of acute Zika virus infection with concurrent GBS suggesting a parainfectious complication,” first author Sandeep Rana, MD, and colleagues noted. Read more. 

Five healthy lifestyle choices tied to dramatic cut in dementia risk

Combining four of five healthy lifestyle choices has been linked to up to a 60% reduced risk for Alzheimer’s dementia in new research that strengthens ties between healthy behaviors and lower dementia risk. “I hope this study will motivate people to engage in a healthy lifestyle by not smoking, being physically and cognitively active, and having a high-quality diet,” lead investigator Klodian Dhana, MD, PhD, said in an interview. 

They defined a healthy lifestyle score on the basis of the following factors: not smoking; engaging in 150 min/wk or more of physical exercise; light to moderate alcohol consumption; consuming a high-quality Mediterranean-DASH Diet Intervention for Neurodegenerative Delay diet (upper 40%); and engaging in late-life cognitive activities.

“What needs to be determined is how early should we start ‘behaving.’ We should all aim to score four to five factors across our entire lifespan, but this is not always feasible. So, when is the time to behave? Also, what is the relative weight of each of these factors?” said Luca Giliberto, MD, PhD. Read more.

Marijuana for migraine? Some tentative evidence

Medical marijuana may have promise for managing headache pain, according to results from a small study conducted at the Jefferson Headache Center at Thomas Jefferson University. The researchers found general satisfaction with medical marijuana, more frequent use as an abortive medication rather than a preventative, and more than two-thirds using the inhaled form rather than oral.

“A lot of patients are interested in medical marijuana but don’t know how to integrate it into the therapy plan they already have – whether it should be just to treat bad headaches when they happen, or is it meant to be a preventive medicine they use every day? We have some data out there that it can be helpful, but not a lot of specific information to guide your recommendations,” said Jefferson headache fellow Claire Ceriani, MD, in an interview. Read more.

Inside Mercy’s mission to care for non-COVID patients in Los Angeles

When the hospital ship USNS Mercy departed San Diego’s Naval Station North Island on March 23, 2020, to support the Department of Defense efforts in Los Angeles during the coronavirus outbreak, Commander Erin Blevins remembers the crew’s excitement was palpable. “We normally do partnerships abroad and respond to tsunamis and earthquakes,” said Cdr. Blevins, MD, a pediatric hematologist-oncologist who served as director of medical services for the mission.

Between March 29 and May 15, about 1,071 medical personnel aboard the Mercy cared for 77 patients with an average age of 53 years who were referred from 11 Los Angeles area hospitals. 

Care aboard the ship ranged from basic medical and surgical care to critical care and trauma. The most common procedures were cholecystectomies and orthopedic procedures, and the average length of stay was 4-5 days, according to Cdr. Blevins. Over the course of the mission, the medical professionals conducted 36 surgeries, 77 x-ray exams, 26 CT scans, and administered hundreds of ancillary studies ranging from routine labs to high-end x-rays and blood transfusion support. Special Feature.

Medical marijuana may have promise for managing headache pain, according to results from a small study conducted at the Jefferson Headache Center at Thomas Jefferson University. The researchers found general satisfaction with medical marijuana, more frequent use as an abortive medication rather than a preventative, and more than two-thirds using the inhaled form rather than oral.

Many patients ask about medical marijuana, but there is relatively little data on its effects on headache. Studies are generally retrospective, and often focus on marijuana use for general pain, with subset analyses looking at headache, according to coauthor Claire Ceriani, MD, who is a headache fellow at Jefferson. “A lot of patients are interested in medical marijuana but don’t know how to integrate it into the therapy plan they already have – whether it should be just to treat bad headaches when they happen, or is it meant to be a preventive medicine they use every day? We have some data out there that it can be helpful, but not a lot of specific information to guide your recommendations,” said Dr. Ceriani in an interview.

Although the research is far from a final word on the subject, it did have some take-home messages, said Dr. Ceriani. “Most people seem to find it effective as an abortive medication that might be able to take the place of some of the prescription medications that they were previously using,” she said.

The study was part of the virtual annual meeting of the American Headache Society.
 

An effective abortive therapy?

The study began shortly after the Jefferson Headache Center became certified to offer medical marijuana around the beginning of 2019. “We wanted to start keeping track of these patients from the get-go so we’d be able to learn as much as possible from them and help guide the recommendations we give to patients in the future,” said Dr. Ceriani.

The study included 48 patients with migraine or other types of chronic headache who received medical marijuana treatment between January and September 2019. After collecting baseline information from medical records and questionnaires filled out at marijuana treatment initiation, the researchers followed up periodically with telephone questionnaires to assess treatment response and side effects. About half of the participants (56.3%) reported daily headache. 14.6% had posttraumatic headache, 10.4% new daily persistent headache, and 4.2% tension-type headache. Additional symptoms were common, including anxiety (72.9%) and insomnia (62.5%).

A total of 28 subjects completed a follow-up questionnaire over the phone. Out of the 28 participants , 3 had stopped using marijuana. Of 25 subjects who continued use, 71.4% used it two or more times per week, and 25.0% used it every day. Among participants, 50% used a THC-dominant strain of marijuana. Overall, 71.4% used an inhaled form.

Side effects included dry mouth/throat (46.4%), dry/red eyes (35.7%), fatigue/lethargy (35.7%), and increased appetite (35.7%).

Before starting on marijuana, 46.4% of the subjects used abortive medications at least 10 days per month. After starting marijuana treatment, the rate dropped to 25.0%. Marijuana use was associated with improvements in anxiety: 57.1% who had anxiety reported improvement with marijuana use, as did 78.6% with insomnia. On a scale of 10, the average rating of marijuana’s usefulness was 5.9, and 17.9% rated it as 10.
 

Several concerns

The study has numerous limitations. It has a small sample size, it is from a single center, and the patient population had relatively severe symptoms. Such studies are “fraught with possible bias,” said Andrew Charles, MD, professor of neurology and director of the UCLA Goldberg Migraine Program, when asked to comment.

He pointed out that one key concern for marijuana is concerns over worsening of the condition or refractoriness caused by medication overuse. The cannabinoid receptors it acts on bear some similarity to opioid receptors, and opioid overuse headache is well known. The recent changes in marijuana laws makes it an important issue, one that patients often asked about. But prospective clinical trials face a range of roadblocks: Marijuana remains a controlled substance, it would be difficult to create a placebo control, and no large companies are likely to sponsor such a trial.

“But I think it’s important to keep talking about and developing evidence as much as we can and addressing not just the benefits but also being keenly aware of the possible adverse effects, especially medication overuse,” said Dr. Charles.

The authors also acknowledged the study’s limitations, “but I think there is value, because there are definitely specific patterns we were able to find in terms of what’s helpful for patients, and we also found that a lot of patients also have other disorders in addition to headache, like anxiety and insomnia. And we found that those patients in particular seemed to have more benefit than most with medical marijuana,” said coauthor Angela Hou, MD, who is also a headache fellow at Jefferson.

Dr. Hou and Dr. Ceriani cautioned against use of marijuana in any patient with a substance use disorder, as well as the inhaled form in patients with chronic lung conditions.

The study received no funding. Dr. Ceriani and Dr. Hou had no relevant financial disclosures. Dr. Charles has consulted for Amgen, Biohaven, Eli Lilly, Novartis, and Lundbeck.

Here are the stories our MDedge editors across specialties think you need to know about today:

Headache may predict clinical evolution of COVID-19

Headache may be a key symptom of COVID-19 that predicts the disease’s clinical evolution, new research suggests. An observational study of more than 100 patients showed that headache onset could occur during the presymptomatic or symptomatic phase of COVID-19.

Headache itself was associated with a shorter symptomatic period, while headache and anosmia were associated with a shorter hospitalization period. 

It seems that those patients who start early on, during the asymptomatic or early symptomatic period of COVID-19, with headache have a more localized inflammatory response that may reflect the ability of the body to better control and respond to the infection,” lead investigator Patricia Pozo-Rosich, MD, PhD, said at the virtual annual meeting of the American Headache Society.

Pilot study shows apremilast effective for severe recurrent canker sores

Apremilast was highly effective in treating patients with severe recurrent aphthous stomatitis, with rapid response and an excellent safety profile, results from a small pilot study showed.

Apremilast is approved by the FDA for psoriasis and was shown in a recent phase 2 trial to be effective for Behçet’s disease aphthosis.

Dr. Alison Bruce and colleagues found that, within 4 weeks of therapy, complete clearance of RAS lesions occurred in all patients except one in whom ulcers were reported to be less severe. Remission in all patients was sustained during 16 weeks of treatment, Dr. Bruce noted at the virtual annual meeting of the American Academy of Dermatology. Read more.

Where does dexamethasone fit in with diabetic ketoacidosis in COVID-19?

A new article in the Journal of Clinical Endocrinology & Metabolism (JCEM) addresses unique concerns and considerations regarding diabetic ketoacidosis (DKA) in the setting of COVID-19.

“Hospitals and clinicians need to be able to quickly identify and manage DKA in COVID patients to save lives. This involves determining the options for management, including when less intensive subcutaneous insulin is indicated, and understanding how to guide patients on avoiding this serious complication,” corresponding author Marie E. McDonnell, MD, said in an Endocrine Society statement.

The new article briefly touches on the fact that upward adjustments to intensive intravenous insulin therapy for DKA may be necessary in patients with COVID-19 who are receiving concomitant corticosteroids or vasopressors. But it was written prior to the June 16 announcement of the “RECOVERY” trial results with dexamethasone. The UK National Health Service immediately approved the drug’s use in the COVID-19 setting, despite the fact that there has been no published article on the findings yet.

“The peer review will be critical. It looks as if it only benefits people who need respiratory support, but I want to understand that in much more detail,” said Dr. McDonnell. Read more.

It seems that those patients who start early on, during the asymptomatic or early symptomatic period of COVID-19, with headache have a more localized inflammatory response that may reflect the ability of the body to better control and respond to the infection,” lead investigator Patricia Pozo-Rosich, MD, PhD, said at the virtual annual meeting of the American Headache Society.

Pilot study shows apremilast effective for severe recurrent canker sores

Apremilast was highly effective in treating patients with severe recurrent aphthous stomatitis, with rapid response and an excellent safety profile, results from a small pilot study showed.

Apremilast is approved by the FDA for psoriasis and was shown in a recent phase 2 trial to be effective for Behçet’s disease aphthosis.

Dr. Alison Bruce and colleagues found that, within 4 weeks of therapy, complete clearance of RAS lesions occurred in all patients except one in whom ulcers were reported to be less severe. Remission in all patients was sustained during 16 weeks of treatment, Dr. Bruce noted at the virtual annual meeting of the American Academy of Dermatology. Read more.

Where does dexamethasone fit in with diabetic ketoacidosis in COVID-19?

A new article in the Journal of Clinical Endocrinology & Metabolism (JCEM) addresses unique concerns and considerations regarding diabetic ketoacidosis (DKA) in the setting of COVID-19.

“Hospitals and clinicians need to be able to quickly identify and manage DKA in COVID patients to save lives. This involves determining the options for management, including when less intensive subcutaneous insulin is indicated, and understanding how to guide patients on avoiding this serious complication,” corresponding author Marie E. McDonnell, MD, said in an Endocrine Society statement.

The new article briefly touches on the fact that upward adjustments to intensive intravenous insulin therapy for DKA may be necessary in patients with COVID-19 who are receiving concomitant corticosteroids or vasopressors. But it was written prior to the June 16 announcement of the “RECOVERY” trial results with dexamethasone. The UK National Health Service immediately approved the drug’s use in the COVID-19 setting, despite the fact that there has been no published article on the findings yet.

“The peer review will be critical. It looks as if it only benefits people who need respiratory support, but I want to understand that in much more detail,” said Dr. McDonnell. Read more.

Headache may be a key symptom of COVID-19 that predicts the disease’s clinical evolution in individual patients, new research suggests. An observational study of more than 100 patients showed that headache onset could occur during the presymptomatic or symptomatic phase of COVID-19 and could resemble tension-type or migraine headache.

Headache itself was associated with a shorter symptomatic period, while headache and anosmia were associated with a shorter hospitalization period. In a subgroup of participants, headache persisted even after the symptoms of COVID-19 had been resolved.

Investigators noted that understanding the pathophysiology of headache in COVID-19 could improve understanding of migraine and other headache disorders. “It seems that those patients who start early on, during the asymptomatic or early symptomatic period of COVID-19, with headache have a more localized inflammatory response that may reflect the ability of the body to better control and respond to the infection by SARS-CoV-2,” lead investigator Patricia Pozo-Rosich, MD, PhD, head of the headache and craniofacial pain unit at Vall d’Hebron University Hospital, Barcelona, said in an interview.

She presented the findings at the virtual annual meeting of the American Headache Society.

Systemic inflammation

Headache is one of the main symptoms of COVID-19. A recent study of 214 patients with COVID-19 showed that approximately 13% of the participants had headache and 5% had anosmia.

SARS-CoV-2 penetrates the cells through the ACE2 receptor, which is present throughout the body. “SARS-CoV-2 enters the body through the nasal cavity and it probably penetrates the nervous system in the periphery through afferent branches of the olfactory and trigeminal nerve,” Dr. Pozo-Rosich said. It travels to the lungs and, later, the bloodstream. This generates systemic inflammation that may turn into a cytokine storm. Evidence has identified cortical hyperintensities and olfactory bulb hyperintensities in patients with COVID-19, suggesting that the virus directly infects the CNS.

Interleukin-6, one of the main inflammatory molecules, has been proven to be related to COVID-19 and has become a therapeutic target. Levels of IL-6 may be lower and tend to be more stable in patients with both COVID-19 and headache than in patients with COVID-19 only.

The researchers observed 130 patients (51% women; mean age, 54 years) with COVID-19 who were attended by neurologists at Vall d’Hebron. In this group, 74.4% had headache. Patients with headache tended to be younger than those without headache (mean age, 50 years vs. 63 years, respectively) and tended to be women (58.6% vs. 29.4%).

Approximately one-third of patients with headache had a history of migraine. Most reported mild to moderate pain that resembled tension-type headache. In participants with severe pain and migraine-like features, headache more often began during the asymptomatic phase of COVID-19.

Disease evolution predictor?

The investigators followed up on 100 of the 130 patients with COVID-19, of whom 74 had headache. About 38% of these patients had ongoing headache after 6 weeks, which suggests that some patients may develop a new daily persistent headache once a 3-month period has elapsed. Half of this group had no previous headache history. Headache had been the prodromal symptom of COVID-19 for 21.4% of these patients.

Results showed that headache predicted the clinical evolution of COVID-19. The symptomatic phase of COVID-19 was 7 days shorter for patients with headache than for those without headache. In addition, the period of hospitalization was 7 days shorter for patients with headache and anosmia, compared with patients who had neither headache nor anosmia.

Most therapies, including ibuprofen, candesartan, and anti–calcitonin gene–related peptide (CGRP) monoclonal antibodies, are safe for treating headache in COVID-19, the investigators noted. “We should just try to initially avoid steroids to avoid interference with the body’s reaction to SARS-CoV-2,” Dr. Pozo-Rosich said.

Researchers at Sidney Kimmel Medical College, Philadelphia, are currently studying intranasal vazegepant, an anti-CGRP therapy, as a way to potentially blunt the severe inflammatory response in the lungs of patients with COVID-19, she noted, adding that this peptide may have a future role not only in headache, but also in COVID-19.

Historical link to viral infections

Commenting on the study, Matthew S. Robbins, MD, associate professor of neurology at Weill Cornell Medicine, New York, said the findings associating headache with a shorter symptomatic phase of COVID-19 were “interesting.”

“Headache is common with mild viral infections. More severe viral infections may simply feature more overwhelming respiratory symptoms and fever that lead to underreporting or underascertainment of headache,” said Dr. Robbins, who was not involved with the research.

He noted that the finding showing an association of headache and COVID-19 with a younger age and in women “may be related to a higher prevalence of migraine biology in such patients, and being triggered by the virus or the psychological stress associated with it.”

Dr. Robbins added that viral illnesses have long been associated with new daily persistent headache, “dating back to the early 1980s,” when it was first described in association with Epstein-Barr virus. These infections have also been implicated in the progression of migraine to chronic migraine in adolescents.

“In my view, treatment should be aimed at the symptomatic headache type for which new daily persistent headache resembles, regardless of the potential inciting factor,” Dr. Robbins said.

Dr. Pozo-Rosich has received consulting fees from Allergan, Amgen, Almirall, Biohaven, Chiesi, Eli Lilly, Medscape, Novartis, and Teva Pharmaceuticals. Dr. Robbins has disclosed no relevant financial relationships.

Adjunctive preventive therapy with a calcitonin gene–related peptide monoclonal antibody (CGRP-mAb) medication is safe and effective in patients with chronic migraine who have only achieved a partial response to onabotulinumtoxinA (Botox) treatment. Investigators found the CGRP-mAbs significantly reduced the number of headache days and pain severity with adverse event rates similar to those reported in previous trials of these medications.

“The addition of a CGRP monoclonal antibody provided statistically significantly fewer monthly headache days,” said study investigator Fred Cohen, MD, an internal medicine resident physician at Montefiore Health System, New York. “However, this was a retrospective chart review, which is hindered by elements such as recall bias. Therefore, future prospective studies are warranted for higher quality data.”

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

Fewer headache days

Although Botox is associated with significant clinical improvement in chronic migraine, it often fails to adequately control headache frequency and additional medications are needed.

The CGRP-mAbs fremanezumab, galcanezumab, and erenumab, have recently been approved for migraine prevention, with results from clinical trials demonstrating they are effective for both chronic and episodic migraine. However, patients treated with Botox were excluded from these trials and to date there are no data on combination treatment with Botox and CGRP-mAbs.

To determine whether adjunctive treatment with CGRP-mAbs augments Botox therapy in chronic migraine the investigators conducted a retrospective chart review of patients receiving Botox and prescribed a CGRP-mAb.

Eligible patients met the International Classification of Headache Disorders, 3rd edition, criteria for chronic migraine; were age 18 years or older; and presented at a single headache center between May 2018 and May 2019. Patients who received another new therapy during the study or those taking CGRP-mAb treatment for less than 2 months were excluded.

The study’s primary outcome was change in the number of reported monthly headache days, and change in pain severity was the secondary outcome.

The final analysis included data on 153 patients. The population’s mean age was 47.1 years, and 139 patients (90.8%) were women. In all, 89 patients (58.0%) received erenumab (35 received 70 mg and 54 received 140 mg), 51 (33.0%) received galcanezumab, and 13 (9.0%) received fremanezumab.

Overall, 114 (74.5%) patients reported a decrease in monthly headache days or pain severity. In the group of 66 patients for whom quantitative data were available, the average number of monthly headache days before Botox treatment was 25.7. After Botox treatment, patients had an average decrease of 10.9 monthly headache days, a 42.4% reduction, so on average study participants continued to have an average of 14.8 monthly headache days.

After treatment with a CGRP-mAb the number decreased by 5.6 additional days (37.8%). Patients receiving combined therapy had an average of 9.1 monthly headache days. The total decrease from baseline was 16.6 fewer monthly headache days, a 64.6% reduction.

The number of headache days per month was reduced to 9.3 for erenumab and galcanezumab and 5.8 for fremanezumab. However, few patients in the study took fremanezumab so this result had less statistical power than the results for the other CGRP-mAbs.

A total of 13 patients (8.5%) reported side effects associated with the CGRP-mAbs, which included constipation, injection-site reaction, and fatigue.
 

More evidence is needed

Commenting on the findings, Peter McAllister, MD, medical director of the New England Institute for Neurology and Headache in Stamford, Conn., said the study’s main limitation is that it is a retrospective chart review, which yields lower level evidence than a prospective, double-blind, placebo-controlled study. Dr. McAllister, who was not involved in the research, also noted that the sample size was small, particularly with respect to fremanezumab.

“This study, despite its limitations, shows that addition of a monoclonal antibody to onabotulinumtoxinA is safe and well tolerated, and may confer additional reduction in migraine or headache days. The authors correctly state that more evidence via prospective study is warranted,” said Dr. McAllister, who is also chief medical officer of the New England Institute for Clinical Research and was not involved in the investigation.

Dr. Cohen has reported no relevant financial relationships. Dr. McAllister was an investigator in the PREEMPT trial of onabotulinumtoxinA, as well as in all of the phase 3 monoclonal antibody studies.

People with high-frequency episodic migraine and low-frequency chronic migraine may have similar treatment needs because characteristics of the two disorders overlap significantly, calling into question the existing threshold of 15 migraine headache days per month to distinguish low- and high-frequency migraine, according to an analysis of almost 17,000 patients from the Chronic Migraine Epidemiology and Outcomes (CaMEO) study presented at the virtual annual meeting of the American Headache Society.

“The results showed substantial overlap in levels of burden, anxiety, depression and health utilization, including outpatient, inpatient and emergency department visits, among CaMEO respondents with high-frequency episodic migraine and those with low-frequency chronic migraine,” said Richard B. Lipton, MD, of the Albert Einstein College of Medicine, New York.

The study analyzed data on 16,789 respondents to CaMEO, the longitudinal, web-based study designed to characterize the course of episodic and chronic migraine. The study population consisted of four subgroups based on the number of self-reporting monthly headache days (MHDs):

• Low- and moderate-frequency episodic migraine (LFEM; zero to seven MHDs; n = 13,473).
• High-frequency episodic migraine (HFEM; 8-14 MHDs; n = 1,840).
• Low-frequency chronic migraine (LFCM; 15-23 MHDs; n = 1,035).
• High-frequency chronic migraine (HFCM; 24 or more MHDs; n = 441).

Dr. Lipton pointed out that the International Classification of Headache Disorders, 3rd edition, defines chronic migraine as 15 or more MHDs for 3 months or more with criteria for migraine with or without aura met on 8 days a month or more. It defines episodic migraine as less than 15 MHDs.

The study characterized migraine subgroups by various demographics. “The more frequent headache categories were associated with slightly older age of onset with a higher proportion of BMI [body mass index] in the obese range and overall with lower levels of household income and education,” Dr. Lipton said.
 

Similar headache characteristics

A comparison of headache characteristics and headache-related disabilities across subgroups revealed a number of commonalities between the HFEM and LFCM subgroups, Dr. Lipton said. Among them were presence of mild to severe allodynia, disability grade, interictal burden, and anxiety and depression scores. For example, 47.3% of the HFEM subgroup and 54.9% of the LFCM subgroup had Patient Health Questionnaire–9 depression test scores greater than 10.

The study also evaluated patterns of consultation, diagnosis, and health resource utilization and found similar rates between the HFEM and LCFM subgroups, Dr. Lipton said. Rates of overnight hospital stay in the past 6 months were almost identical between the two subgroups: 4.1% for the former and 4.2% for the latter. One striking difference between the two subgroups: the rate of medication overuse per ICHD-3 recommendations was 40.5% in HFEM and 63% in LFCM.

“These finding suggest that the treatment needs of people with HFEM may be similar to those of people with LFCM, suggesting that the 15-MHD threshold currently recommended by the ICHD-3 may merit reconsideration,” Dr. Lipton said.
 

An arbitrary cutoff?

The findings raise a valid point about reevaluating the thresholds for low- and high-frequency migraine, said Andrew Charles, MD, director of the Goldberg Migraine Program at the University of California, Los Angeles. “My own personal view is that they’re the same thing,” he said of HFEM and LFCM; The 15-day cutoff, he said, is “somewhat arbitrary.”

Dr. Charles suggested migraine categories address frequency and not characteristics – episodic versus chronic – and use a range rather than a threshold. “Define a range that’s more like 10-20 days per month rather than having that point at 15,” Dr. Charles said. “People sometimes make the mistake of thinking that that classification reflects some underlying pathophysiology, and that may not be necessarily true.”

Dr. Lipton disclosed financial relationships with Alder Biopharmaceuticals, Allergan (now AbbVie), Amgen, Biohaven Pharmaceuticals, Dr. Reddy’s/Promius, Electrocore, Eli Lilly, eNeura Therapeutics, GlaxoSmithKline, Lundbeck (Alder), Merck, Pernix Therapeutics, Pfizer, Supernus, Teva, Trigemina, Axsome Therapeutics, Vector, and Vedanta. Dr. Charles disclosed he is a consultant to Amgen, Biohaven Pharmaceuticals, Eli Lilly, Lundbeck, and Novartis.

People with high-frequency episodic migraine and low-frequency chronic migraine may have similar treatment needs because characteristics of the two disorders overlap significantly, calling into question the existing threshold of 15 migraine headache days per month to distinguish low- and high-frequency migraine, according to an analysis of almost 17,000 patients from the Chronic Migraine Epidemiology and Outcomes (CaMEO) study presented at the virtual annual meeting of the American Headache Society.

“The results showed substantial overlap in levels of burden, anxiety, depression and health utilization, including outpatient, inpatient and emergency department visits, among CaMEO respondents with high-frequency episodic migraine and those with low-frequency chronic migraine,” said Richard B. Lipton, MD, of the Albert Einstein College of Medicine, New York.

Lung ultrasound works well in children with COVID-19

Lung ultrasound has “high concordance” with radiologic findings in children with COVID-19 and offers benefits over other imaging techniques, such as CT. “First, it may reduce the number of radiologic examinations, lowering the radiation exposure of the patients,” wrote Marco Denina, MD, and colleagues from the pediatric infectious diseases unit at Regina Margherita Children’s Hospital in Turin, Italy. “Secondly, when performed at the bedside, [lung ultrasound] allows for the reduction of the patient’s movement within the hospital; thus, it lowers the number of health care workers and medical devices exposed to [SARS-CoV-2].” The findings of the small, observational study were published in Pediatrics.

New hypertension definitions reveal preclampsia risk

Using the new clinical definitions of hypertension, pregnant women with even modest elevations in blood pressure are at increased risk for preeclampsia, according to results from a large retrospective cohort study. Elizabeth F. Sutton, PhD, of the University of Pittsburgh and colleagues looked at records from 18,162 women who had given birth to a single baby. The authors found preeclampsia risk increased with increasing blood pressure elevation. Among women with normal blood pressure before 20 weeks’ gestation, 5% had preeclampsia, while 7% of those with elevated blood pressure did, as did 12% of women with stage 1 hypertension and 30% of women with stage 2 hypertension. The increase in risk of preeclampsia was because of preterm preeclampsia in the women with elevated blood pressure. Preeclampsia researcher Mark Santillan, MD, PhD, of the University of Iowa in Iowa City, said in an interview that the results “open the door to considering these new blood pressure categories as a prognosticator” for preeclampsia. “This paper furthers the field by applying these new categories to hypertensive diseases in pregnancy, which are not well studied” in comparison to nonpregnant hypertensive states.

Face mask type matters when sterilizing

When sterilizing face masks, the type of mask and the method of sterilization have a bearing on subsequent filtration efficiency, according to new research published in JAMA Network Open. The greatest reduction in filtration efficiency after sterilization occurred with surgical face masks. With plasma vapor hydrogen peroxide (H2O2) sterilization, filtration efficiency of N95 and KN95 masks was maintained at more than 95%, but for surgical face masks, filtration efficiency was reduced to less than 95%. With chlorine dioxide (ClO2) sterilization, on the other hand, filtration efficiency was maintained at above 95% for N95 masks, but for KN95 and surgical face masks, filtration efficiency was reduced to less than 80%.

FDA approves first treatment for adult-onset Still’s disease

The Food and Drug Administration has expanded the indications for canakinumab (Ilaris) to include all patients with active Still’s disease older than 2 years, adding adult-onset Still’s disease (AOSD) to a previous approval for juvenile-onset Still’s disease, also known as systemic juvenile idiopathic arthritis (sJIA). That makes Ilaris the first approved treatment for AOSD. The results from a randomized, double-blind, placebo-controlled study of 36 patients with AOSD aged 22-70 years showed that the efficacy and safety data in AOSD were generally consistent with the results of a pooled analysis of sJIA patients, according to Novartis, which markets canakinumab.

Intranasal DHE shows promise in migraine

An intranasal form of dihydroergotamine (DHE) targeting the upper nasal region is safe and effective for the treatment of migraine, according to results from a phase 3 clinical trial. The new formulation could offer patients an at-home alternative to intramuscular infusions or intravenous injections currently used to deliver DHE. The STOP 301 phase 3 open-label safety and tolerability trial treated over 5,650 migraine attacks in 354 patients who self-administered INP104 for up to 52 weeks. They were provided up to three doses per week (1.45 mg in a dose of two puffs, one per nostril). A total of 66.3% of participants reported pain relief by 2 hours following a dose, and 38% had freedom from pain. Read more.

A combination of rizatriptan and the nonsteroidal anti-inflammatory drug (NSAID) meloxicam formulated to improve oral absorption led to better pain control than did rizatriptan alone in a phase 3 clinical trial. The combination (AXS-07), in development by Axsome Therapeutics, was also safe and well tolerated, according to Cedric O’Gorman, MD, Axsome senior vice president for clinical development and medical affairs. It was tested in subjects who had inadequately responded to previous treatment and who had an average of 2-8 migraines per month.

The therapy combines 10-mg rizatriptan with 20-mg meloxicam delivered by the company’s MoSEIC technology. “Treatment with AXS-07 resulted in rapid, sustained, substantial, and statistically significant effect as compared with rizatriptan and placebo. The enhanced effect of AXS-07 may be especially relevant for patients with more difficult-to-treat migraine,” said Dr. O’Gorman during a presentation of the study at the virtual annual meeting of the American Headache Society.

Matthew Robbins, MD, said in an interview, “This combination may be particularly useful for patients who want to take an oral medication but still need rapid and sustained pain freedom.” Dr. Robbins is the neurology residency program director at New York Presbyterian Hospital and an associate professor of neurology at Weill Cornell Medicine, New York. He was not involved in the research.

The study randomized 1,594 patients 2:2:2:1 to AXS-07, rizatriptan alone, MoSEIC meloxicam alone, or placebo, which could be administered immediately after a migraine event. Between 35% and 40% of participants across the groups had previously used triptans. The mean migraine treatment optimization questionnaire (mTOQ4) score was 3.6, indicating that the population was made up of people with poor responses to medication. Among patients in the study group, 37%-43% had severe pain intensity, 41%-47% were obese, and 35%-37% had morning migraine.

At 2 hours, more patients in the AXS-07 group than in the placebo group were pain free (19.9% vs. 6.7%; P < 0.001). They were also more likely to experience freedom from the most bothersome symptom at 2 hours (36.9% vs. 24.4%; P = 0.002). Secondary outcome measures favored the AXS-07 group when compared with the rizatriptan-only group, including 1-hour pain relief (44% vs. 37%; P = 0.04), 2- to 24-hour sustained pain relief (53% vs. 44%; P = 0.006), 2- to 48-hour sustained pain relief (47% vs. 37%; P = 0.003), 2- to 24-hour sustained pain freedom (16% vs. 11%; P = 0.038), 2- to 48-hour sustained pain freedom (15% vs. 8.8%; P = 0.003), rescue medication use (23% vs. 35%; P < 0.001), a rating of much or very much improved on the Patient Global Impression of Change (PGI-C) scale (47% vs. 39%; P = 0.022), and functional improvement at 24 hours (64% vs. 56%; P = 0.027).

“The percentage of patients achieving pain relief with AXS-07 was numerically greater than with rizatriptan at every time point measure, starting at 15 minutes, and was statistically significant by 60 minutes. This is significant because rizatriptan is widely recognized as the fastest-acting and one of the most effective oral triptans,” said Dr. O’Gorman.

The frequency of adverse events was 11.0% in the AXS-07, 15.4% in the rizatriptan group, 11.5% in the meloxicam group, and 6.0% in the placebo group.

“The added benefit of this study was the demonstration of efficacy in patients who have previously failed other acute treatments. We know that ineffective acute treatments are a likely risk factor for the progression of episodic migraine to chronic migraine, and the more options that we have for our patients, the better,” Dr. Robbins commented.

He remains concerned about cost and access, however. A limited number of tablets per month for acute treatments prompt clinicians to prescribe the medications individually and advise patients to take them in combination. “Rizatriptan is generally available in 12 monthly tablets by many coverage plans, and I would hope that, if ultimately FDA approved, a similar allotment is made affordable and accessible,” he said.

The study was funded by Axsome Therapeutics. Dr. O’Gorman is an employee of Axsome. Dr. Robbins has no relevant financial disclosures.

The frequency of adverse events was 11.0% in the AXS-07, 15.4% in the rizatriptan group, 11.5% in the meloxicam group, and 6.0% in the placebo group.

“The added benefit of this study was the demonstration of efficacy in patients who have previously failed other acute treatments. We know that ineffective acute treatments are a likely risk factor for the progression of episodic migraine to chronic migraine, and the more options that we have for our patients, the better,” Dr. Robbins commented.

He remains concerned about cost and access, however. A limited number of tablets per month for acute treatments prompt clinicians to prescribe the medications individually and advise patients to take them in combination. “Rizatriptan is generally available in 12 monthly tablets by many coverage plans, and I would hope that, if ultimately FDA approved, a similar allotment is made affordable and accessible,” he said.

A combination of rizatriptan and the nonsteroidal anti-inflammatory drug (NSAID) meloxicam formulated to improve oral absorption led to better pain control than did rizatriptan alone in a phase 3 clinical trial. The combination (AXS-07), in development by Axsome Therapeutics, was also safe and well tolerated, according to Cedric O’Gorman, MD, Axsome senior vice president for clinical development and medical affairs. It was tested in subjects who had inadequately responded to previous treatment and who had an average of 2-8 migraines per month.

The therapy combines 10-mg rizatriptan with 20-mg meloxicam delivered by the company’s MoSEIC technology. “Treatment with AXS-07 resulted in rapid, sustained, substantial, and statistically significant effect as compared with rizatriptan and placebo. The enhanced effect of AXS-07 may be especially relevant for patients with more difficult-to-treat migraine,” said Dr. O’Gorman during a presentation of the study at the virtual annual meeting of the American Headache Society.

Matthew Robbins, MD, said in an interview, “This combination may be particularly useful for patients who want to take an oral medication but still need rapid and sustained pain freedom.” Dr. Robbins is the neurology residency program director at New York Presbyterian Hospital and an associate professor of neurology at Weill Cornell Medicine, New York. He was not involved in the research.

The study randomized 1,594 patients 2:2:2:1 to AXS-07, rizatriptan alone, MoSEIC meloxicam alone, or placebo, which could be administered immediately after a migraine event. Between 35% and 40% of participants across the groups had previously used triptans. The mean migraine treatment optimization questionnaire (mTOQ4) score was 3.6, indicating that the population was made up of people with poor responses to medication. Among patients in the study group, 37%-43% had severe pain intensity, 41%-47% were obese, and 35%-37% had morning migraine.

At 2 hours, more patients in the AXS-07 group than in the placebo group were pain free (19.9% vs. 6.7%; P < 0.001). They were also more likely to experience freedom from the most bothersome symptom at 2 hours (36.9% vs. 24.4%; P = 0.002). Secondary outcome measures favored the AXS-07 group when compared with the rizatriptan-only group, including 1-hour pain relief (44% vs. 37%; P = 0.04), 2- to 24-hour sustained pain relief (53% vs. 44%; P = 0.006), 2- to 48-hour sustained pain relief (47% vs. 37%; P = 0.003), 2- to 24-hour sustained pain freedom (16% vs. 11%; P = 0.038), 2- to 48-hour sustained pain freedom (15% vs. 8.8%; P = 0.003), rescue medication use (23% vs. 35%; P < 0.001), a rating of much or very much improved on the Patient Global Impression of Change (PGI-C) scale (47% vs. 39%; P = 0.022), and functional improvement at 24 hours (64% vs. 56%; P = 0.027).

“The percentage of patients achieving pain relief with AXS-07 was numerically greater than with rizatriptan at every time point measure, starting at 15 minutes, and was statistically significant by 60 minutes. This is significant because rizatriptan is widely recognized as the fastest-acting and one of the most effective oral triptans,” said Dr. O’Gorman.

The calcitonin gene–related peptide receptor monoclonal antibodies (CGRP mAbs)for treatment of migraine have gained wide acceptance since their approval in 2018, but a real-world study has reported adverse event rates higher than those the preapproval clinical trials reported and has found that patients who fail on one of the treatments are likely to fail again if they’re switched to another.

At the virtual annual meeting of the American Headache Society, Larry Robbins, MD, assistant professor of neurology at Chicago Medical School, North Chicago, reported on the results of his postapproval study of 369 migraine patients taking one of the three approved CGRP mAbs. “If patients do not do well on one mAb, it is sometimes worthwhile to switch, but most patients do not do well from the second or third mAb as well,” Dr. Robbins said in an interview. “In addition, there are numerous adverse effects that were not captured in the official phase 3 studies. Efficacy has held up well, but for a number of reasons, the true adverse event profile is often missed.”
 

Assessing efficacy and adverse events

In evaluating the efficacy of the three approved CGRP mAbs, Dr. Robbins used measures of degree of relief based on percentage decrease of symptoms versus baseline and the number of migraine days, combined with the number of moderate or severe headache days. Most of the patients kept calendars and were interviewed by two headache specialists. The study also utilized a 10-point visual analog scale and averaged relief over 3 months.

Of the patients on erenumab (n = 220), 10% described 95%-100% relief of symptoms, 24% reported 71%-100% relief, 34% described 31%-70% relief, and 43% experienced 0%-30% relief. Adverse events among this group included constipation (20%), nausea (7%), increased headache and fatigue (5% for each), and joint pain and depression (3% for each). Three patients on erenumab experienced unspecified serious adverse reactions.

In the fremanezumab group (n = 79), 8% described 95%-100% relief, 18% had 71%-100% relief, 33% experienced 31%-70% improvement, and 50% had 30% improvement or less. Adverse events in these patients included nausea, constipation, and depression (6% each); increased headache and muscle pain or cramps (5% each); rash, joint pain, anxiety, fatigue, or weight gain (4% for each ); and injection-site reactions, irritability, or alopecia (3% combined).

Patients taking galcanezumab (n = 70) reported the following outcomes: 3% had 95%-100% relief of symptoms, 14% had 71%-100% relief, 46% with 31%-70% relief, and 40% had 0%-30% relief. This group’s adverse events included constipation (10%); depression and increased headache (6% for each); nausea, fatigue, or injection-site reactions (4% each ); and muscle pain or cramps, rash, anxiety, weight gain, or alopecia (3% each).

Dr. Robbins also assessed switching from one CGRP mAb to another for various reasons. “When the reason for switching was poor efficacy, only 27% of patients did well,” he stated in the presentation. “If the reason was adverse events, 33% did well. When insurance/financial reasons alone were the reason, but efficacy was adequate, 58% did well after switching.”

Overall, postapproval efficacy of the medications “held up well,” Dr. Robbins noted. “Efficacy after 2 months somewhat predicted how patients would do after 6 months.” Among the predictors of poor response his study identified were opioid use and moderate or severe refractory chronic migraine at baseline.

However, the rates of adverse events he reported were significantly greater than those reported in the clinical trials, Dr. Robbins said. He noted four reasons to explain this discrepancy: the trials did not use an 18-item supplemental checklist that he has advocated to identify patients at risk of side effects, the trials weren’t powered for adverse events, patients in the trials tended to be less refractory than those in the clinic, and that adverse events tend to be underreported in trials.

“Adverse events become disaggregated, with the same descriptors used for an adverse event,” Dr. Robbins said. “Examples include fatigue, somnolence, and tiredness; all may be 1%, while different patients are describing the same adverse event. It is possible to reaggregate the adverse events after the study, but this is fraught with error.”
 

Uncovering shortcomings in clinical trials

Emily Rubenstein Engel, MD, director of the Dalessio Headache Center at the Scripps Clinic in La Jolla, Calif., noted that Dr. Robbins’ findings are significant for two reasons. “Dr. Robbins has uncovered a general flaw in clinical trials, whereby the lack of consistency of adverse event terminology as well as the lack of a standardized questionnaire format for adverse events can result in significant under-reporting of adverse events,” she said.

“Specifically for the CGRPs,” Dr. Engel continued, “he has raised awareness that this new class of medication, however promising from an efficacy standpoint, has side effects that are much more frequent and severe than seen in the initial clinical trials.”

Dr. Robbins reported financial relationships with Allergan, Amgen and Teva. Dr. Engel has no financial relationships to disclose.

An intranasal form of dihydroergotamine (DHE) targeting the upper nasal region is safe and effective for the treatment of migraine, and ranks high in patient satisfaction, according to results from a phase 3 clinical trial. In development by Impel NeuroPharma, the new formulation could offer patients an at-home alternative to intramuscular infusions or intravenous injections currently used to deliver DHE.

“Our analysis of the data suggests that nothing new or untoward seemed to be happening as a result of delivering DHE to the upper nasal space,” Stephen Shrewsbury, MD, chief medical officer of Impel NeuroPharma, said in an interview. The company released key results from its phase 3 clinical trial, while a poster examining patient satisfaction was presented by Dr. Shrewsbury at the virtual annual meeting of the American Headache Society.
 

An improved intranasal formulation

The product isn’t the first effort to develop an inhaled form of DHE. An inhaled version called Migranal, marketed by Bausch Health, delivers DHE to the front part of the nose, where it may be lost to the upper lip or down the throat, according to Dr. Shrewsbury. Impel’s formulation (INP104) delivers the drug to the upper nasal space, where an earlier phase 1 trial demonstrated it could achieve higher serum concentrations compared with Migranal.

In 2018, MAP Pharmaceuticals came close to a product, but it was ultimately rejected by the Food and Drug Administration because DHE was not stable in the propellant used in the formulation. This time is different, said Dr. Shrewsbury, who was chief medical officer at MAP before joining Impel. The new device holds DHE and the propellant in separate compartments until they are combined right before use, which should circumvent stability problems.

Dr. Shrewsbury believes that patients will welcome an inhaled version of DHE. “People with migraines don’t want to have to go into hospital or even an infusion center if they can help it,” he said.

The study was one of a number of presentations at the AHS meeting that focused on novel delivery methods for established drugs. “The idea of taking things that we know work and improving upon them, both in terms of formulation and then delivery, that’s a common theme. My impression is that this will be an interesting arrow to have in our sling,” said Andrew Charles, MD, professor of neurology and director of the UCLA Goldberg Migraine Program, who was not involved in the study.
 

Open-label trial results

The STOP 301 phase 3 open-label safety and tolerability trial treated over 5,650 migraine attacks in 354 patients who self-administered INP104 for up to 52 weeks. They were provided up to three doses per week (1.45 mg in a dose of two puffs, one per nostril). Maximum doses included two per day and three per week.

There were no new safety signals or concern trends in nasal safety findings. 15.0% of patients experienced nasal congestion, 6.8% nausea, 5.1% nasal discomfort, and 5.1% unpleasant taste.

A total of 66.3% of participants reported pain relief by 2 hours (severe or moderate pain reduced to mild or none, or mild pain reduced to none) following a dose, and 38% had freedom from pain. 16.3% reported pain relief onset at 15 minutes, with continued improvement over time. During weeks 21-24 of the study, 98.4% and 95% of patients reporting no recurrence of their migraine or use of rescue medications during the 24- and 48-hour periods after using INP104. “Once they got rid of the pain, it didn’t come back, and that’s been one of the shortcomings of many of the available oral therapies – although some of them can be quite effective, that effect can wear off and people can find their migraine comes back within a 24- or 48-hour period,” said Dr. Shrewsbury.

The drug was also rated as convenient, with 83.6% of participants strongly agreeing (50%) or agreeing (33.6%) that it is easy to use.

“It certainly looks like compliance will be good. The possibility is that this will be quite useful,” said Dr. Charles, who is also enthusiastic about some of the other drug formulations announced at the meeting. “It really is just fun times for us as clinicians to be able to have so many different options for patients,” he said.

A total of 66.3% of participants reported pain relief by 2 hours (severe or moderate pain reduced to mild or none, or mild pain reduced to none) following a dose, and 38% had freedom from pain. 16.3% reported pain relief onset at 15 minutes, with continued improvement over time. During weeks 21-24 of the study, 98.4% and 95% of patients reporting no recurrence of their migraine or use of rescue medications during the 24- and 48-hour periods after using INP104. “Once they got rid of the pain, it didn’t come back, and that’s been one of the shortcomings of many of the available oral therapies – although some of them can be quite effective, that effect can wear off and people can find their migraine comes back within a 24- or 48-hour period,” said Dr. Shrewsbury.

The drug was also rated as convenient, with 83.6% of participants strongly agreeing (50%) or agreeing (33.6%) that it is easy to use.

“It certainly looks like compliance will be good. The possibility is that this will be quite useful,” said Dr. Charles, who is also enthusiastic about some of the other drug formulations announced at the meeting. “It really is just fun times for us as clinicians to be able to have so many different options for patients,” he said.

Dr. Shrewsbury is an employee of Impel NeuroPharma, which funded the study.* Dr. Charles consults for Amgen, BioHaven, Eli Lilly, Novartis, and Lundbeck.
