ICYMI Multiple Sclerosis

NASHVILLE, TENNESSEE — A second-generation anti-CD40L monoclonal antibody suppresses multiple sclerosis (MS) disease activity on MRI to an uncommonly high degree, new trial data suggested.

Researchers found a near absence of new brain lesions at 48 weeks in patients on the highest dose. At this level of disease suppression, there was no evidence of increased infection risk, which investigators said might relate to its mechanism of action. In addition, there were no thrombotic events, which is what defeated a first-generation drug in this same class.

Among those initially randomly assigned to receive 1200 mg every 4 weeks, 96% were free of new gadolinium-positive (Gd+ T1) lesions at 48 weeks, reported investigator Yang Mao-Draayer, MD, PhD, director of Clinical and Experimental Therapeutics at the Oklahoma Medical Research Foundation’s Multiple Sclerosis Center of Excellence, Oklahoma City. Annual relapse rates were also low.

The findings were presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.
 

No Effect on Lymphocyte Count

As previously reported, 12-week frexalimab results were noteworthy because they provided validation for CD40L as a target in the control of MS. One of the unique features of this therapy relative to many other immunomodulatory therapies is that it has shown little, if any, effect on lymphocyte counts or immunoglobulin levels.

In the double-blind randomized phase 2 trial, 125 patients with MS of all other MS therapy were randomized in a 4:4:4:1 ratio to 1200-mg frexalimab administered intravenously every 4 weeks after a loading dose, to 300-mg frexalimab administered subcutaneously every 2 weeks after a loading dose, or to one of the two matching placebo arms.

For the primary endpoint of new Gd+ T1 lesions at the end of the blinded study, the rates at week 12 were 0.2 and 0.3 in the higher- and lower-dose treatment groups, respectively, and 1.4 in the pooled placebo groups.

At 48 weeks, the results were even better. From 12 weeks, the rate of Gd+ T1 lesions in the high-dose group continued to fall, reaching 0.1 at week 24 and 0.0 at week 48. In the lower-dose group, there was also a stepwise decline over time with a value of 0.2 at week 48. The annual relapse rate at week 48 was 0.4.
 

Reengineered Agent

In the placebo groups, the same type of suppression of disease activity was observed after they were switched to active therapy at the end of 12 weeks.

By 24 weeks, the number of new Gd+ T1 lesions had fallen to 0.3 in placebo patients switched to the higher dose and 1.0 in those switched to the lower dose.

By week 48, the rates were 0.2 in both of the switch arms.

The proportions of patients free of new Gd+ T1 lesions at 48 weeks were 96% in the group started and maintained on the highest dose of frexalimab, 87% in those started and maintained on the lower dose, 90% in those started on placebo and switched to the highest dose of frexalimab, and 92% of placebo patients switched to the lower dose.

“T2 lesion volume from baseline through week 48 was stable in patients who continued receiving frexalimab and decreased in placebo participants after switching to frexalimab at week 12,” Dr. Mao-Draayer reported.

The CD40-CD40L co-stimulatory pathway that regulates both adaptive and innate immune responses has been pursued as a target for MS therapies for decades, Dr. Mao-Draayer said.

A first-generation monoclonal antibody directed at elevated levels of CD40L, which is implicated in the inflammation that drives MS, showed promise but was abandoned after it was associated with an increased risk for thromboembolic events in a phase 1 trial, she said.

However, the second-generation agent was engineered to avoid an interaction with platelets, which played a role in the risk for thrombosis associated with the failure of the earlier drug.

As with the first-generation agent, frexalimab had little or no impact on lymphocyte count or immunoglobulin G and immunoglobulin M levels. Both remained stable during the 12-week controlled trial and through the ongoing open-label extension, Dr. Mao-Draayer said.

This might be a factor in the low level of adverse events. Most importantly, there have been no thromboembolic events associated with frexalimab so far, but the follow-up data also show rates of infection and other events, such as nasopharyngitis, that were comparable with placebo in the 12-week controlled trial and have not increased over longer-term monitoring.

Such adverse events as headache and COVID-19 infection have also occurred at rates similar to placebo.

Two phase 3 trials are underway. FREXALT is being conducted in relapsing-remitting MS. FREVIV has enrolled patients with nonrelapsing secondary progressive MS.
 

Impressively Low New Lesion Count

Commenting on the findings, Jeffrey Cohen, MD, director of the Mellen Center for Multiple Sclerosis, Cleveland Clinic, who was not involved in the research, said that over the course of the extended follow-up, MS activity in the central nervous system as measured with new Gd+ T1 lesions was impressively low. 

He noted that the phase 2 open-label follow-up continues to support the promise of frexalimab. But Dr. Cohen cautioned that this does not obviate the need for phase 3 data.

In particular, he said that an immunomodulatory agent that does not affect the lymphocyte count has a theoretical advantage, but pointed out that the benefit is still presumably mediated by blocking pathways that mediate autoimmune activity.

Even if lymphocyte count is unaffected, the immunomodulatory pathway by which frexalimab does exert its benefit might pose a different set of risks, he said.

“We will not have sufficient data to judge the promise of this agent until the phase 3 trials are completed,” he said.

Dr. Mao-Draayer reported financial relationships with Acorda, Bayer, Biogen, Bristol Myers Squibb, Celgene, EMD Serono, Genentech, Horizon, Janssen, Novartis, Questor, Teva, and Sanofi, which provided funding for the phase 2 frexalimab trial. Dr. Cohen reported financial relationships with Astoria, Convelo, EMD Serono, FiND, INmune, and Sandoz.

NASHVILLE, TENNESSEE — Fatigue and sleep problems are common among patients with multiple sclerosis (MS), but there are ways to help them manage these difficulties through personalized care.

Fatigue related to MS is complex, but it often follows a pattern. “Oftentimes when I meet with patients for the first time, they’re not always sure [what their own pattern is]. They know that the fatigue is present, and it’s limiting their activities. It’s important for us to break down and see that pattern for [the patient] specifically, and what are some ways that we can intervene to perhaps make that pattern something that improves quality of life and day-to-day living,” said Grace Tworek, PsyD, during a presentation at the annual meeting of the Consortium of Multiple Sclerosis Centers (CMSC).

A cycle may start on a day that a patient has lots of energy. They are ambitious that day and get a lot done on their “to do” list while they have the energy. Unfortunately, they commonly overdo it, leading to fatigue the next day. Over ensuing days, the patient might feel unable to engage in everyday tasks and begin to feel they are falling behind. This in turn can affect mood, resulting in increased symptoms of depression and anxiety. That leads to days of inactivity and rest, which leads to recovery. Then comes a day with better mood and increased energy, where the cycle can begin again.

It’s an addressable problem. “What we really want to do is break this cycle, get out of those peaks and valleys of high energy days and very low energy days to try to create more sustainable patterns” said Dr. Tworek, who is a staff health psychologist at Cleveland Clinic’s Mellen Center for Multiple Sclerosis, Cleveland, Ohio.
 

Fatigue

When addressing fatigue in MS patients, Dr. Tworek and her colleagues begin with a fatigue diary that includes typical activities engaged in throughout the day. It also distinguishes between activities the patient feels are important and activities that give them satisfaction.

“If we can find ways to include these [satisfying] activities, and not focus only on those important activities. This is where that quality of life really comes into play. But I always say to folks, we are not striving for perfection at first. I want you to write down what’s actually happening so we can use this data to later inform how we are going to make changes,” said Dr. Tworek.

It’s also important to encourage patients to seek help. Activities that are neither important nor satisfying may not need doing at all, and they encourage patients to seek help in other tasks. As for tasks that are important in their day-to-day lives, “How can we break those down? We break those down by pacing activities,” said Dr. Tworek.

A simple way to pace yourself is to use “The rule of two.” It asks: How long can I do a task before I experience a two-point increase on a 1-10 fatigue scale. “At that time, is when we want to start inserting breaks. We want to find activities we can do that will reduce [fatigue] or get us back to baseline. Or if that’s not realistic, keep us where we are at rather than increasing fatigue,” said Dr. Tworek.

Another way to think about it is spoon theory, sometimes referred to as coin theory. The idea is that you wake up each morning with ten spoons. Each task on a given day will cost a certain number of spoons. “You might start your day, you go downstairs, you have breakfast, and you’re already down to seven points, the next day, you might still be at 10. So it’s really about monitoring where you’re at in terms of how many coins or spoons you’re spending so that we can then reflect on how many coins or spoons do I have left?” said Dr. Tworek.

The strategy can aid communication with partners or family members who may have difficulty understanding MS fatigue. “Sometimes putting a number to it can really open up the doors to having these difficult conversations with friends and family,” said Dr. Tworek.
 

Sleep

Fatigue and sleep are naturally intertwined, and sleep problems are also common in MS, with 30%-56% reporting problems, depending on the estimate.

One concept to think about is sleep drive. “From the moment we wake up, we are building sleep pressure, just like from the moment you stop eating, your body starts building pressure to eat again,” said Dr. Tworek.

Naps can interfere with that drive, much like a snack can rob you of a meal-time appetite. “A nap is going to curb that appetite for sleep, making it more difficult potentially to fall asleep,” said Dr. Tworek. If a nap is absolutely necessary, it’s better to do it earlier in the day to allow time to build sleep pressure again.

As with fatigue, Dr. Tworek has patients fill out a sleep diary that documents difficulty falling or staying asleep, timing and length of awakenings, quality of sleep, length and timing of any naps, and other factors. It sometimes reveals patterns, like difficulty falling asleep on specific days of the week. Such rhythms may be attributable to regular stressors, like anticipating some event the next morning. Then it might be possible to tie in other techniques like stress management to reduce accompanying anxiety.

Sleep hygiene is an important factor, employing strategies like staying off screens or social media while in bed. “About 1 hour before bedtime, we want to try to create some relaxation time,” said Dr. Tworek.

Her clinic also emphasizes consistent wake time. “If we are waking every day in about the same half hour period, we are able to build that sleep pressure consistently. [Then] your body is going to let you know when it is time for bed. You’re going to feel sleepiness,” said Dr. Tworek.

Dr. Tworek did not report any disclosures or conflicts of interest.

As with fatigue, Dr. Tworek has patients fill out a sleep diary that documents difficulty falling or staying asleep, timing and length of awakenings, quality of sleep, length and timing of any naps, and other factors. It sometimes reveals patterns, like difficulty falling asleep on specific days of the week. Such rhythms may be attributable to regular stressors, like anticipating some event the next morning. Then it might be possible to tie in other techniques like stress management to reduce accompanying anxiety.

Sleep hygiene is an important factor, employing strategies like staying off screens or social media while in bed. “About 1 hour before bedtime, we want to try to create some relaxation time,” said Dr. Tworek.

Her clinic also emphasizes consistent wake time. “If we are waking every day in about the same half hour period, we are able to build that sleep pressure consistently. [Then] your body is going to let you know when it is time for bed. You’re going to feel sleepiness,” said Dr. Tworek.

Dr. Tworek did not report any disclosures or conflicts of interest.

NASHVILLE, TENNESSEE — Among people with MS who have mild symptoms, non-motor symptoms like dizziness, fatigue, and spasticity predict later perception of balance, walking, and physical quality of life. However, these associations fall away among patients with more severe disease, according to a new study performed in Australia. The findings could eventually help tailor physical activity interventions.

The research grew out of frustrations with developing interventions focused on strength. “There are many systematic reviews showing stronger and stronger evidence that exercise is beneficial. It does change your walking. It does improve your balance,” said Katrina Williams, PhD, during a presentation of the results at the annual meeting of the Consortium of Multiple Sclerosis Centers.

However, when her group’s intervention studies yielded no statistically significant improvements, she began to search for explanations, and began to suspect heterogeneity among MS patients. Their clinic took all comers, regardless of disability level. “[Our attitude was] we will make it work. We’ll get you actively moving and exercising. But when you break down a lot of those systematic reviews, there’s not a lot of teasing out of disability levels. So, potentially, it is the disability level that might be leading to why some people don’t change or why we’re not getting the statistically significant benefits, because we’re not addressing the individual at their level of disease progression,” said Dr. Williams, who is a senior lecturer in physiotherapy at the University of Queensland, Brisbane, Australia.

“Physiotherapists, we love exercise, we love movement, but we’re a bit unidimensional. It’s some strength training, [or] let’s get on that bike and do cardiovascular. But that may not be enough for individuals who have different symptoms profiles. We’re assuming that the motor profile is the most important, and the one that needs to be addressed in these individuals,” said Dr. Williams.
 

Focusing on Non-Motor Symptoms

When she searched the literature, she could find little evidence of non-motor symptoms correlating to walking, balance, or even quality of life. To dig deeper, her group studied 220 MS patients in Australia who self-reported symptoms of dizziness, vision problems, fatigue, and spasticity. The population had a mean age of 42 years, and 82% were female. They ranged in disease severity from disease step (DS) 0 to DS 6. The researchers categorized respondents as between DS 0 (mild symptoms that were mostly sensory) to DS 3 (MS interferes with walking) and from DS 4 (early cane use) to DS 6 (requiring bilateral walking support).

Deficits were more commonly reported in the DS 4-6 group than the DS 0-3 group with respect to light touch (88% vs 72%), proprioception (63% vs 41%), fatigue (100% vs 96%), and spasticity (78% vs 69%). There were no significant differences in dizziness, vision, or memory/cognition/emotion.

A linear regression model incorporating sensory worsening, age, social participation, perceived deficit, and spasticity showed an R² adjusted value of 0.73. However, when they looked only at DS 0-3 patients, the R² value strengthened to 0.86. Among the DS 4-6 group, the correlation largely disappeared with an R² value of 0.16. Specifically, there were stronger associations in the DS 0-3 group than the overall group (DS 0-6) between perceived walking deficit and sensory worsening (R² 0.45 vs 0.31), fatigue (0.67 vs 0.05), spasticity (0.47 vs 0.16), and balance (0.8 vs 0.16).

“Most non-motor symptoms do have moderate to weak correlations to walking confidence and walking balance, and quality of life, and the correlations do decline as disability worsens. Those with less disability had more correlations that were stronger, particularly for the walking and balance confidence. So [among those] walking without an aid, there are more non-motor correlations aligned to the actual outcomes. In more disabled, they fell away, so there’s something else going on that we do have to look at,” said Dr. Williams.

She called for other clinicians to explore non-motor symptoms in patients with less disability, and the relationships of those symptoms to gait, balance, and overall MS impact, in the hopes that such observations could improve the tailoring of physiotherapy programs.
 

Perception May Differ From Actual Function

During the Q&A session, Nora Fritz, PhD, an associate professor of neurology at Wayne State University, Detroit, Michigan, asked about the lack of correlations seen in more disabled patients. “It’s not exactly what you would expect to happen,” said Dr. Fritz, in an interview.

She asked Dr. Williams if the study had sufficient power to detect associations in patients with more severe disability, since the study had a relatively small sample size and many predictors in its regression model. Dr. Fritz also noted that perceptions may differ from actual function, so actual function can’t be captured using a survey. Dr. Williams responded that the group is now working to incorporate more clinical measures to their correlations.

Another audience member said she was “perplexed” by the drop-off of correlation in the most severe group. She suggested the possibility that as patients become more disabled, they may be less likely to perceive the relatively less severe non-motor symptoms and therefore did not report them.

Dr. Williams and Dr. Fritz have no relevant financial disclosures.

NASHVILLE, TENNESSEE — Stress in patients with multiple sclerosis (MS) can have serious effects on quality of life, but there is some evidence that it could worsen inflammation through activation of pro-inflammatory cytokines, leading to more relapses.

A new intervention seeks to help patients with MS reduce stress using biofeedback, employing simple, readily available pulse oximeters and focusing on breathing and other simple coping skills.

Observational studies have suggested that stress may lead to relapses, according to Amy Sullivan, PsyD, who spoke during a session at the annual meeting of the Consortium of Multiple Sclerosis Centers.

She cited a study conducted during the 34-day war between Israel and Lebanon in 2006, which found more exacerbations among 156 Israeli patients with relapsing-remitting MS patients during the period of hostilities. There were 18 relapses that occurred during the war, and 44% of those who experienced a relapse reported experience intense subjective stress, versus 20% of those who did not experience a relapse, and 67% of relapsers reported high levels of distress linked to rocket attack exposure, versus 42% of those who did not have a relapse (P = .05).

Another study of 216 Lebanese MS patients found 23 relapses during the 2-month war period, compared with a mean of 8.4 during other 2-month periods.

“So we have two observational studies that are showing us that there’s a pretty strong link or correlation between war, a very stressful life event, and MS relapses,” said Dr. Sullivan.

That relationship has prompted development of interventions to reduce stress in MS patients in hopes of improving clinical outcomes. One that “shaped our practice,” according to Dr. Sullivan, was published in 2012. It was the first high-quality randomized controlled trial of such an intervention, she said.

The program was based on cognitive behavioral therapy (CBT) and lasted 24 weeks and 16 psychotherapy sessions. Compared with controls, participants had fewer MRI brain lesions, but there were no differences after week 24. “[That] tells us that when people stopped the stress management techniques, the intervention did not give them protection,” said Dr. Sullivan.

Her group aimed to build on that work by developing a program that would be easier for busy patients to learn and incorporate into their lives. “Being in a psychotherapist office for 24 weeks to me was not feasible. I didn’t think that this was something that individuals would have interest in,” said Dr. Sullivan.

They focused on skills to manage stress, delivered over four sessions and designed to be employed in their private life. “We want them to go into the world for 4 to 6 weeks to do the skills that we taught them in that particular session, and then they come back and they tell us how that worked. We also recognize that each skill is not going to work. It’s not a one-size-fits-all for each person,” said Dr. Sullivan.

In addition to patient self-reports, the team measured physiological indicators of stress like pulse (beats per minute), breath rate (breaths per minute), and saturated oxygen (%SpO2). The measures were taken before and after stress management exercises.

The first session included psychoeducation and diaphragmatic breathing for relaxation. The second reviewed the nervous system and the stress response. The third introduced visualization and guided imagery that was individualized for each patient. The fourth focused on mindfulness and distress tolerance.

The study included 195 individuals (mean age, 44.4 years; 72.0% female, 71.5% White).

In all four sessions, patients achieved significant in-session improvements in breath rate, pulse, and saturated oxygen, as well as improvements from the first to the final session: Among 124 patients who completed at least 2 sessions, Patient Health Questionnaire-9 (PHQ-9) scores improved by 1.61 (P < .001), Generalized Anxiety Disorder (GAD) scores by 1.08 (P = .004), breaths per minute by 3.38 (P = .001), and SpO2 by 1.67 (P = .016). There was no significant change in pulse.

The high dropout rate could be seen as a weakness, but it was actually designed into the program. “We encouraged people to drop out when they were done. Our program is built on feasibility, and it’s built based on wanting our patients to get what they need out of our treatment, and then go live their lives. We don’t want them to feel tied to our offices, so they voluntarily discontinued after they felt they had sufficiently mastered stress management skills,” said Dr. Sullivan.

The results “suggest that short-term treatment with stress management skills can impact physiological and emotional stress in MS. [The] stress management protocol is likely a great adjunctive treatment to bolster skills traditionally taught during psychotherapy sessions,” said Dr. Sullivan.

During the Q&A period, an audience member asked why the group deviated from traditional cognitive behavioral therapy and moved into more right-brain activities. “In our practice, we’re very eclectic. We don’t believe that just CBT helps, or just behavioral therapy helps, or just [dialectical behavior therapy] helps. We want to teach the skills which we believe are the most important skills to train people on,” said Dr. Sullivan.

Dr. Sullivan did not report any relevant disclosures.

NASHVILLE, TENNESSEE — Individuals with multiple sclerosis are living longer, healthier lives. More than half of patients with MS are 55 years or older, and the incidence of late-onset MS is rising.

This can lead to complex treatment decisions, according to Amy Perrin Ross, APN, MSN, CNRN, MSCN, who is the neuroscience program coordinator at Loyola Medical Center in Maywood, Illinois.

“Age was ranked as the second most important factor affecting treatment decisions in a recent survey of MS specialists,” said Ms. Ross, during a presentation at the annual meeting of the Consortium of Multiple Sclerosis Centers. But there is little evidence to support treatment decisions, since there are few older patients enrolled in clinical trials. The average age is around 30-34 years.
 

MS in Older Patients

Aging is associated with immune system changes. There is a decline in inflammatory activity and an accompanying 17% reduction in the relapse rate with every 5 years of advancing age, and the majority of relapses occur within 30 years of onset. The bad news is that patients have reduced capacity to recover from relapses as they age.

“When I’m talking to patients about pros and cons [of treatment], I do mention that, yes, your relapse rate might be less, but as we age, we have less of an ability to completely recover,” said Ms. Ross.

The efficacy of disease-modifying therapies (DMTs) goes down with advancing age. One meta-analyis of 38 randomized trials and 13 therapies found that benefit with respect to disease progression generally disappeared by the age of 53. “Age is an essential modifier of drug efficacy,” said Ms. Ross.

On the other hand, another meta-analysis found that success in treating relapses was similar across age groups. “So it seems that we can successfully treat our patients’ relapses: There was no significant association between age and reductions in annualized relapse rate,” she said, though she noted that clinical trial populations are likely to be dissimilar to aging patients, many of whom have gone years without experiencing a relapse.

Aging can also lead to differences in potential adverse effects of DMTs. Patients with MS experience faster immunosenescence, in which normal changes to the innate and adaptive immune system are accelerated. This can lead to greater risk of infection, and other adverse events can include post-administration reactions and changes to serum IgG levels.

Other conditions that should be monitored for include progressive multifocal leukoencephalopathy, and malignancies are more prevalent among people with MS than the general population, although it is unclear if this is due to the use of DMTs or other factors, or even just coincidence, said Ms. Ross. “Those are all things to keep in mind as we’re pushing forward with therapy for patients,” she said.

Comorbidities that occur with aging can also affect treatment outcomes, and could tip the balance against use of DMTs in some situations.
 

What Does the Literature Say?

There has been a range of retrospective studies looking at the results of discontinuation of DMTs with advancing age, and the results have been mixed. Some factors are associated with greater likelihood of disease reactivation, including younger age, female sex, shorter duration without a relapse, MRI activity, and degree of disability.

A study of a French registry including patients aged 50 years and older who went off DMTs found that 100% of patients who discontinued therapy were on older injectable DMTs, and 34.9% of that group restarted therapy over a mean follow-up of 7 years. The risk of relapse or disability progression was similar between the groups, but discontinuers who started with Expanded Disability Status Scale (EDSS) scores lower than 6.0 were more likely to reach an EDSS score of 6.0.

The DISCOMS study compared 259 patients randomized to continue DMTs versus discontinuation of DMTs. “What they found was that noninferiority was not shown. Disease activity, such as relapses and new lesions, [occurred in] 12% of the discontinuers and 5% of the continuers,” said Ms. Ross.

One option to balance risk and benefit is DMT de-escalation, with the aim to match disease therapy with disease activity over time. A 2023 survey of 224 neurologists to identify characteristics in older patients that would prompt de-escalation. The most common reasons were overall safety or comorbidity concerns (62% endorsed), high risk of infection (59%), low disease activity or stable disease (50%), concerns about efficacy (41%), high disability (37%), and patient choice (36%). About 7% reported that they generally do not de-escalate.

The preferred de-escalation therapies included glatiramer acetate (29%), fumarates (27%), teriflunomide (23%), and interferon betas (21%).

Ms. Ross noted that the study was likely conducted around the height of the COVID-19 pandemic. “So I wonder if some of these results might be a little bit different [than if it was conducted at a different time],” she said.
 

Other Concerns and Options

During the Q&A session, one audience member asked if physicians should consider low-efficacy medications in older patients with the idea that they at least get a little bit of protection.

Patricia Coyle, MD, who also presented during the session, framed her response around whether the patient had relapsing or progressive MS. “If somebody has had relapsing MS and has never transitioned to progressive MS, and they’re 70, maybe they don’t need to be on any DMT. If there’s no longer a focal inflammatory relapsing phase, if we could feel confident on that possibility, then maybe they don’t need to be on a relapsing DMT,” said Dr. Coyle, who is director of the MS Comprehensive Care Center at Stony Brook University Medical Center in Stony Brook, New York.

Alternatively, if a patient has progressive MS, she said she would recommend discontinuing treatment if she believes the patient is being harmed by it, to focus instead on health and wellness.

Another questioner wondered what to do with a 70-year-old patient who has had no infections, has normal IgG, but insists on continuing high-efficacy B-cell therapy. Dr. Coyle responded that she would tell the patient that she believes it isn’t offering any benefit, but if the patient insisted, she would continue: “I’m not living with MS the way they are. If they tell me, ‘I believe it’s helping me and I want to stay on it,’ then so long as I don’t think I’m overtly harming them, I’m going to treat them.”

Ms. Ross agreed, and suggested that ceding to the patient’s will is an important consideration. “I think sometimes what we’re doing, if we’re not causing harm, what we’re doing is bolstering these people’s ability to continue to have hope, and that in my mind is a big part of managing their disease,” she said.

NASHVILLE, TENNESSEE — Individuals with multiple sclerosis are living longer, healthier lives. More than half of patients with MS are 55 years or older, and the incidence of late-onset MS is rising.

This can lead to complex treatment decisions, according to Amy Perrin Ross, APN, MSN, CNRN, MSCN, who is the neuroscience program coordinator at Loyola Medical Center in Maywood, Illinois.

“Age was ranked as the second most important factor affecting treatment decisions in a recent survey of MS specialists,” said Ms. Ross, during a presentation at the annual meeting of the Consortium of Multiple Sclerosis Centers. But there is little evidence to support treatment decisions, since there are few older patients enrolled in clinical trials. The average age is around 30-34 years.
 

MS in Older Patients

Aging is associated with immune system changes. There is a decline in inflammatory activity and an accompanying 17% reduction in the relapse rate with every 5 years of advancing age, and the majority of relapses occur within 30 years of onset. The bad news is that patients have reduced capacity to recover from relapses as they age.

“When I’m talking to patients about pros and cons [of treatment], I do mention that, yes, your relapse rate might be less, but as we age, we have less of an ability to completely recover,” said Ms. Ross.

The efficacy of disease-modifying therapies (DMTs) goes down with advancing age. One meta-analyis of 38 randomized trials and 13 therapies found that benefit with respect to disease progression generally disappeared by the age of 53. “Age is an essential modifier of drug efficacy,” said Ms. Ross.

On the other hand, another meta-analysis found that success in treating relapses was similar across age groups. “So it seems that we can successfully treat our patients’ relapses: There was no significant association between age and reductions in annualized relapse rate,” she said, though she noted that clinical trial populations are likely to be dissimilar to aging patients, many of whom have gone years without experiencing a relapse.

Aging can also lead to differences in potential adverse effects of DMTs. Patients with MS experience faster immunosenescence, in which normal changes to the innate and adaptive immune system are accelerated. This can lead to greater risk of infection, and other adverse events can include post-administration reactions and changes to serum IgG levels.

Other conditions that should be monitored for include progressive multifocal leukoencephalopathy, and malignancies are more prevalent among people with MS than the general population, although it is unclear if this is due to the use of DMTs or other factors, or even just coincidence, said Ms. Ross. “Those are all things to keep in mind as we’re pushing forward with therapy for patients,” she said.

A unique autoantibody signature of multiple sclerosis (MS) is detectable in the blood of people with the disease years before symptom onset, according to a new study.

Investigators screened blood samples from 250 individuals with MS drawn 5 years before and 1 year after symptom onset, profiled MS-related autoantibodies, and compared the sample with 250 matched controls.

A unique cluster of autoantibodies was found in 10% of people with MS, appearing up to 5 years before the onset of clinical symptoms and remaining higher 1 year after diagnosis. 

“Our work demonstrates that a subset of MS patients has antibodies that react to a common protein motif, both before, during, and after diagnosis and symptom onset,” said lead investigator Colin R. Zamecnik, PhD, a postdoctoral researcher at UCSF School of Medicine, University of California, San Francisco.

Such a discovery could aid in early diagnosis, Dr. Zamecnik added. MS treatments “have gotten much better in the last 15-20 years and evidence shows early treatment can improve outcomes,” he said. 

The study was published online in Nature Medicine.
 

Seeking Earlier Diagnosis

Previous research shows that nonspecific neurologic episodes occur more frequently in people who received an MS diagnosis later in life, pointing to the possibility of an MS prodrome, the authors noted.

These neurologic episodes may be indicative of ongoing neuroinflammatory processes in the preclinical period, they added. Studies in several other autoimmune diseases show that diagnostic autoantibodies can appear years before symptom onset. However, no such antibodies have previously been identified in MS patients. 

To investigate, the researchers turned to data from a large, prospective incident MS cohort assembled during the Gulf War era in more than 10 million US military veterans.

Records of those with the earliest diagnosis (an average of 5 years before symptom onset) and 1 year after the first attack were analyzed, and matched controls were selected.

Investigators used a technique called phage display immunoprecipitation sequencing to screen human blood for antibodies. They conducted a whole-proteome autoantibody screen and serum neurofilament light (sNfL) measurements on these samples in both case patients and controls at the same time points. 
 

Early Signs of Injury

In the preclinical serum samples, sNfL levels were higher nearer the date of diagnosis and significantly higher in post- versus pre-onset samples in people with MS. “Together, these data provide evidence that at least some people with MS exhibit early signs of neuroaxonal injury long before onset of symptoms,” the authors noted.

Analysis of the collection of peptides, described by the investigators as an “autoantibody signature,” was consistent over time and was present regardless of diagnosis. 

Further analysis of the autoantibodies revealed a characteristic protein motif found in common viruses, including Epstein-Barr virus (EBV) and hepatitis C virus, among others.

The motif “shares remarkable similarity to those found on many pathogens that infect humans, including EBV, which is known to be a risk factor for development of MS,” Dr. Zamecnik said.

The researchers validated these findings by analyzing serum and cerebrospinal fluid samples from participants in ORIGINS, an MS cohort at the University of California, San Francisco, that enrolled patients at clinical onset. As with the other cohort, 10% of patients had the autoantibody signature. 

The investigators added that the findings detail some of the first autoantigen-specific biomarkers found in preclinical MS. 

“Taken together, our future work will focus on profiling these patients more closely over time to see how they differ from their counterparts and gives further evidence of viral-host crosstalk as a hallmark of this disease,” Dr. Zamecnik said.
 

Not Ready for Prime Time

Commenting on the findings, Bruce Bebo, PhD, executive vice president of research, National Multiple Sclerosis Society, said the study corroborates the “growing appreciation that MS has a prodrome.” 

Such a discovery might “accelerate progress toward the possibility of treating MS ever-earlier in the course of the disease, or possibly even preventing MS from occurring in the first place,” he added.

Dr. Bebo, who was not involved in this research, noted that it was conducted at a single center, is only preliminary, and “has no immediate clinical applicability.”

Also, because this pattern was identified in only 10% of individuals with MS, “an additional hurdle is whether we can identify other patterns in greater numbers of people,” he added.

Immunization with inactivated vaccines while receiving the natalizumab for highly active multiple sclerosis (MS) is safe and immunogenic, with no increased risk for disease progression, new research shows. 

The study, the first to examine vaccine safety and immunogenicity in highly active MS, revealed high seroprotection rates following receipt of vaccines for COVID-19 and hepatitis A and B, regardless of the duration of treatment with natalizumab.

On the basis of these findings, investigators created an algorithm that clinicians can use to map an immunization schedule in patients who might otherwise delay initiation of disease-modifying therapy until they are fully vaccinated.

“We observed seroprotection rates exceeding 90% for hepatitis A and B, and mRNA COVID-19 vaccines, and all vaccines demonstrated a favorable safety profile, with no exacerbation of disease activity detected,” said lead author René Carvajal, MD, of the Department of Neurology-Neuroimmunology, Multiple Sclerosis Centre of Catalonia (Cemcat), Hospital Universitari Vall d’Hebron, Universitat Autònoma de Barcelona, Barcelona, Spain. “This points to potential benefits for patients with highly active MS who require both immunization and high-efficacy therapies that may impact vaccine responses.” 

The study was published online in JAMA Network Open.
 

A Controversial Issue

Today’s high-efficacy therapies for MS may increase the risk of acquiring new infections, reactivate latent pathogens, or worsen ongoing infectious conditions, and immunogenicity of vaccination can be compromised by immunosuppressive agents, particularly CD20 therapies, researchers noted.

As a result, many clinicians opt to delay initiation of such therapies until vaccination schedules are complete to avoid exposure to vaccine-preventable infections. But delaying treatment can potentially affect disease progression. 

Reports of disease worsening following vaccination “have raised controversy around vaccine safety,” the authors wrote. The issue is especially relevant to those with highly active MS due to the scarcity of available data in this population.

The motivation for the study “stemmed from the complex balance clinicians face between initiating highly effective therapies promptly in patients with highly active MS and ensuring adequate protection against preventable infections through vaccination,” Dr. Carvajal said.
 

High Seroprotection Rate

Researchers analyzed data on 60 patients (mean age, 43 years; 44 female; mean disease duration, 17 years) participating in one of two prospectively followed cohorts: The Barcelona Clinically Isolated Syndromes Inception Cohort and the Barcelona Treatment Cohort. Data included demographic, clinical, radiologic, and biological data as well as regular clinical assessments, evaluations of the Expanded Disability Status Scale (EDSS), and MRI scans.

Patients enrolled in the current study had received at least one of these vaccines between September 2016 and February 2022: hepatitis A virus (HAV), hepatitis B virus (HBV; enhanced immunity high load or adjuvanted), or COVID-19 (BNT162b2 [Pfizer-BioNTech], mRAN-1273 [Moderna], or ChAdOx1-S [recombinant; AstraZeneca]).

The researchers conducted a retrospective, self-controlled analysis to compare the annualized relapse rate, EDSS score, and new T2 lesions counts during the 12 months before and after vaccination in patients with short- and long-term treatment duration.

They also compared John Cunningham virus serostatus between the two periods, as well as immunoglobulin G titers for each vaccine.

The global seroprotection rate was 93% (95% CI, 86%-98%). Individual vaccine rates were 92% for HAV, 93% for HBV, and 100% for COVID-19.

There was a significant reduction between the pre- and postvaccination periods in mean relapse rates (P = .004) and median number of new T2 lesions (P  = .01).

There were no changes in EDSS scores before and after vaccinations and duration of natalizumab treatment had no impact on safety and immunogenicity.
 

‘Viable Option’

The researchers used their findings to create a proposed algorithm to inform immunization decisions in patients with highly active MS who require prompt initiation of high-efficacy disease-modifying therapy.

The algorithm is “integrated into a risk-minimization strategy tailored for patients with highly active MS, emphasizing in this case the pivotal role of natalizumab in averting treatment delays and providing adequate protection against potentially severe infections,” Dr. Carvajal said.

Participants who initiated or continued treatment with natalizumab completed their vaccination regimen without any incidents of progressive multifocal leukoencephalopathy (PML) or disease activity rebound following natalizumab discontinuation.

This suggests that using natalizumab for a brief duration might be a “viable option to contemplate,” the authors noted.

Commenting on the findings, Grace Gombolay, MD, assistant professor of pediatrics in the Division of Pediatric Neurology and director of the Pediatric Neuroimmunology and Multiple Sclerosis Clinic, Emory University, Atlanta, Georgia, said the study “demonstrates that vaccines are safe and do not trigger attacks in patients with MS on natalizumab, and that immunity — as measured by antibodies — is preserved in MS patients who receive natalizumab.”

This “contrasts with other treatments, as decreased antibody responses in COVID-19 are noted in certain treatments,” said Dr. Gombolay, who was not part of the study. “If both disease control and immunity against infection are the goals for the patient, then natalizumab is a reasonable option.” 

“However, this must be balanced with other considerations,” she added, including the risk for PML and pregnancy. 

This study was supported by grants from the European Committee for Treatment and Research in Multiple Sclerosis, Instituto de Salud Carlos III, and the European Union. Dr. Carvajal reported receiving grants from Vall d’Hebron Institut de Recerca and the European Committee for Treatment and Research in Multiple Sclerosis and honoraria from Roche, Novartis, BIIB-Colombia, Merck, and Sanofi outside the submitted work. Dr. Gombolay serves as media editor for Pediatric Neurology and as associate editor of the Annals of the Child Neurology Society. She is also a part-time CDC consultant for acute flaccid myelitis and received an honorarium as a speaker at the Georgia Neurological Society meeting, sponsored by Academic CME and TG Therapeutics.

DENVER — Patients with pediatric-onset multiple sclerosis (POMS) are often prescribed low-efficacy disease-modifying therapies (DMTs), but a new retrospective analysis suggests that, like adults, this patient population may benefit from early treatment with high-efficacy DMTs.

“I think it’s very important to highlight that we are seeing that traditionally, kids are just started on lower-efficacy treatments and they keep relapsing. If we can show that when they get transitioned to high-efficacy treatments, the relapses are lessening, I’m hoping that can then push for better clinical trials with pediatric patients included,” said Frederick Bassal, DO, who presented the study during a poster session at the 2024 annual meeting of the American Academy of Neurology. He is a pediatric neurologist at University of California, Davis.

The first line for POMS is generally low-efficacy DMTs like interferon-beta and glatiramer acetate, but these medications may not effectively control disease progression, according to the study authors, and this could lead to pediatric patients being changed to more potent therapies. That can include moderate-efficacy drugs like S1P inhibitors and fumarates, or high-efficacy DMTS such as B cell depletors and alpha 4 integrin receptor antibodies.
 

Treatment Strategies

“Right now what we’re seeing is the conservative approach — starting low and working up with the younger and adolescent patients. I’m speculating, and I want to look more into it. Is [it maybe] because of insurance approval?” said study coauthor Amara Miller, a medical student at the University of Arizona College of Medicine in Phoenix.

The findings aren’t surprising, according to Barbara Giesser, MD, who was asked to comment on the study. “It is in line with what we think we know about people with adult MS — that if you start early on with a more effective therapy, you tend to have better outcomes,” said Dr. Giesser, director of the MS program at the Pacific Neuroscience Institute.

Another reason to consider higher-efficacy DMTs is that children with MS can have cognitive problems and delays. “There’s a suggestion that if you treat with highly-effective DMT that you might be able to abrogate some of that,” said Dr. Giesser.

Among the approximately two dozen FDA-approved disease-modifying therapies for MS, only fingolimod (Gilenya, Novartis) is approved for children and adolescents. “All of the others are used off label, but I think perhaps, if you have more studies that [show] that children do better if you treat with more effective therapies early on, perhaps we might see more on-label indications for use in a pediatric population,” said Dr. Giesser.

The finding that obesity was associated with a higher likelihood of having multiple therapies is also interesting, she said. “We’re beginning to see that obesity in adults as well seems to portend less favorable neurologic outcomes.”
 

Study Methodology

The researchers analyzed data from 135 POMS patients between 2012 and 2023.

The mean age of participants was 15 years, 60% were female, and 120 of 135 were White, while 76 were of Hispanic ethnicity. Overweight and obesity were common, with 36 and 43 participants in each category. The initial therapy was a low-efficacy DMT in 23.0% of participants, moderate-efficacy in 37.0%, and high-efficacy in 24.4%, while 1.5% received some other kind of medication and 14.1% received no medication. The annualized relapse rate was 0.932, and the mean EDSS score was 0.88.

Patients who underwent three or medication changes had lower EDSS scores than those who underwent zero to 2 (P = .00607).

Over the course of the study, the percentage of patients who received high-efficacy DMTs rose from 25.9% to 48.9%, largely due to changes in medication. Of those initially prescribed low-efficacy DMTs, 77.4% were eventually switched to high-efficacy DMTs.

Every patient who underwent three or more medication changes was initially prescribed a low-efficacy DMT.

Patients started on low-efficacy drugs had a mean of 1.42 medication changes, compared with 0.94 in the moderate-efficacy group and 0.51 in the high-efficacy group. The reasons for changing from the first medication included relapse (36), side effects (11), patient choice or compliance (8), and pregnancy (2).

Patients 10 years or younger were more likely to be initially prescribed a low-efficacy therapy (odds ratio [OR], 5.72; P = .0366), while older patients were more likely to be prescribed moderate- or high-efficacy therapies (OR, 14.44; P = .0012).

There were more total medication changes in the low-efficacy group than the high initial DMT group (P = .000305).

Asked what advice they would give to physicians treating POMS patients, Ms. Miller suggested a top-down approach. “We want to look at if maybe we can start with higher efficacy DMT’s and maybe titering it down. That may be an option,” said Ms. Miller.

Dr. Bassal highlighted the importance of shared decision-making. “We want to go over the options, that we recommend higher-efficacy [DMTs] for these reasons. But every individual is different. And there may be fears that are very reasonable that families have. I think in those cases, it’s also reasonable to make a shared decision. And if that means going with something like an oral, moderate- to lower-efficacy [therapy], that’s okay, because compliance is key, and if you start something where the family is afraid of side effects, or there are side effects, then you kind of lost that opportunity,” he said.

Dr. Bassal, Dr. Giesser, and Ms. Miller have no relevant financial disclosures.

Patients started on low-efficacy drugs had a mean of 1.42 medication changes, compared with 0.94 in the moderate-efficacy group and 0.51 in the high-efficacy group. The reasons for changing from the first medication included relapse (36), side effects (11), patient choice or compliance (8), and pregnancy (2).

Patients 10 years or younger were more likely to be initially prescribed a low-efficacy therapy (odds ratio [OR], 5.72; P = .0366), while older patients were more likely to be prescribed moderate- or high-efficacy therapies (OR, 14.44; P = .0012).

There were more total medication changes in the low-efficacy group than the high initial DMT group (P = .000305).

Asked what advice they would give to physicians treating POMS patients, Ms. Miller suggested a top-down approach. “We want to look at if maybe we can start with higher efficacy DMT’s and maybe titering it down. That may be an option,” said Ms. Miller.

Dr. Bassal highlighted the importance of shared decision-making. “We want to go over the options, that we recommend higher-efficacy [DMTs] for these reasons. But every individual is different. And there may be fears that are very reasonable that families have. I think in those cases, it’s also reasonable to make a shared decision. And if that means going with something like an oral, moderate- to lower-efficacy [therapy], that’s okay, because compliance is key, and if you start something where the family is afraid of side effects, or there are side effects, then you kind of lost that opportunity,” he said.

Dr. Bassal, Dr. Giesser, and Ms. Miller have no relevant financial disclosures.

Multiple sclerosis (MS) has three distinct subtypes based on immune markers in patient’s blood, each with slightly different disease trajectories and responses to therapy, a new study suggests.

With further validation, determining a patient’s blood “immune signature,” or endophenotype, before starting immunomodulatory therapy may help predict clinical disease trajectories and lead to more personalized treatment decisions, investigators said.

“The characterization of an endophenotype at timepoints of diagnosis will help to determine likely trajectory of the disease course but also will help to refine the chosen immune therapy,” said Heinz Wiendl, MD, professor and chair, Department of Neurology, University of Münster, Germany. “This is a rationale way of precision medicine for the future.”

The study was published online in Science Translational Medicine.
 

Degenerative and Inflammatory Subtypes

MS is a highly heterogeneous disorder with different clinical manifestations and disease trajectories, making it a challenge to manage. Whether this heterogeneity is reflected by discrete immune signatures in the blood has been unclear.

To investigate, Dr. Wiendl and a multicenter team comprehensively analyzed the immunological properties of blood samples collected from 309 patients with early MS and an independent validation cohort of 232 patients with early MS.

In both cohorts, they found that cellular immune signatures split into three distinct immunological endophenotypes, dubbed E1, E2, and E3.

E1 is characterized by alterations in the CD4 T-cell compartment, with increases in inflammatory cytokines, namely interleukin-17A (IL-17A), IL-22, and granulocyte-macrophage colony-stimulating factor, as well as earlier structural brain damage, more severe disease, and higher disability.

Alterations in natural killer cells are a hallmark of the E2 subtype, while alterations in the CD8 T cells dominate the E3 subtype.

The different subtypes were associated with distinct clinical disease trajectories. E3 patients displayed a pattern reflecting higher inflammatory disease activity, as illustrated by a higher relapse rate (≥ 2) within the first year from baseline and more frequent use of highly active disease-modifying therapies as first immunomodulatory treatment.

E3 patients also had higher numbers of gadolinium-enhancing lesions at baseline, a higher conversion rate from clinically isolated syndrome to relapsing-remitting MS, and rapid disability accrual within 2 years after baseline.

This endophenotype was also associated with an increase in total cell numbers within the cerebrospinal fluid and intrathecal immunoglobulin (Ig) G synthesis at baseline.

E1 patients had a higher degree of early structural brain damage and disease severity, including disability and impaired evident at baseline, and increased serum neurofilament light and increased intrathecal IgM synthesis at baseline.

“According to these different patterns of disease trajectories, we therefore termed these subsets degenerative E1 and inflammatory E3. Overall, although some of the clinical and paraclinical parameters partially overlapped, our analysis reveals that distinct immunological endophenotypes might have predictive value with regard to clinically relevant disease trajectories,” the researchers wrote.
 

Toward Personalized Care

In addition, during up to 4-year follow-up of some patients, they observed that patients with the inflammatory E3 endophenotype treated with interferon-beta exhibited higher disease progression and MRI activity relative to E3 patients receiving other therapies. These differential effects of interferon-beta were not observed in the other endophenotypes.

With further study and refinement, the hope is to make this test a “clinical reality,” Dr. Wiendl said.

Commenting on the findings, Kimberly O’Neill, MD, clinical instructor, Department of Neurology, NYU Grossman School of Medicine, New York City, noted that people with MS can have “a broad variety of disease course and outcomes ranging from mild to a very severe and life-altering disease course. At this point, we are not great at predicting who is going to be on which path and also which medication is right for each patient.

“Research like this gives us hope for a more personalized precision medicine in MS,” said Dr. O’Neill, who was not part of the study. “The ideal world would be to have a blood test that could tell their disease course and which treatments will work for an individual patient, but we are certainly not there yet.”

Also providing an outside perspective, Mary Rensel, MD, director of wellness and pediatric MS at the Cleveland Clinic Mellen Center for MS, Cleveland, said, “Precision medicine is our goal and dream in MS care — to be able to do a blood test and know what medicine a patient may or may not respond to and save them years of ongoing symptoms or the risk of disability. This study is a great start.”

The Epstein-Barr virus (EBV) is our constant companion, infecting an estimated 90%-95% of adults. Many of us are first infected as children, when the germ may trigger cold and flu symptoms. EBV also causes mononucleosis, or kissing disease, a glandular fever that has afflicted generations of amorous young people.

Post infection, EBV settles in for the long haul and remains in the body until death. It’s thought to be largely innocuous, but EBV is now implicated as a cause of several types of cancer — including lymphoma and nasopharyngeal tumors – and multiple sclerosis (MS). In 2022, a landmark study in Science suggested that previous EBV infection is the primary cause of MS.

While there aren’t many implications for current treatment, greater insight into the origin story of MS may eventually help neurologists better diagnose and treat patients, experts said. The goal is to uncover clues that “can help us understand MS a little bit better and reveal insights that could lead to new disease-modifying therapy,” Bruce Bebo, PhD, executive vice president of research with the National MS Society, said in an interview.
 

EBV Boosts MS Risk 32-Fold

EBV was first linked to MS back in 1981. For the 2022 study, researchers at the Harvard T.H. Chan School of Public Health and Harvard Medical School, Boston, analyzed blood serum from 10 million active-duty members of the US military. They focused on 801 recruits with MS and matched them with more than 1500 controls. All but one of those with MS had been infected with EBV; infection appeared to boost the risk for MS 32-fold (95% CI, 4.3-245.3; P < .001).

Neurologist and associate professor Michael Levy, MD, PhD, of Harvard Medical School and Massachusetts General Hospital, said in an interview that the findings are “groundbreaking” and confirm that EBV is “likely the primary cause of MS.”

According to Dr. Levy, there are two main theories about why EBV causes MS. The first hypothesis, known as the “molecular mimicry” theory, suggests that “EBV is a trigger of MS, possibly when the immune system mistakes a viral protein for a myelin protein and then attacks myelin,” Dr. Levy said. In MS, the immune system attacks the protective myelin sheath and the axons it insulates.

“After that point, the virus is not necessary to maintain the disease state and eradicating the virus likely won’t have much effect since the immune response is already triggered,” he said.

The second theory is that “EBV is a driver of MS where there is an ongoing, lifelong immunological response to EBV that continuously causes damage in the central nervous system [CNS]. In theory, if we could eradicate the virus, the destructive immune response could also resolve. Thus, an EBV antiviral treatment could potentially treat and maybe cure MS,” Dr. Levy explained, noting that “removing the pathogenic antigen may be a more effective strategy than removing the immune response.”

However, “we don’t yet know which hypothesis is correct,” he said. But “there is preliminary evidence in favor of each one.”
 

‘Additional Fuses Must Be Ignited’

It’s also unclear why most people infected with EBV do not develop MS. It appears that “additional fuses must be ignited,” for MS to take hold, according to a commentary accompanying the landmark 2022 study.

“As far as clinical implications, knowing whether a patient has a medical or family history of mononucleosis may be a small clue, a small piece of evidence, to help with diagnosis,” Dr. Bebo said.

He agreed with Dr. Levy that an antiviral could be a promising approach “If the problem in MS is a dysfunctional immune response to EBV.”

Natalia Drosu, MD, PhD, a postdoctoral fellow at Harvard-MIT Biomedical Engineering Center, said that a clinical trial of a non-immunosuppressive antiviral targeting EBV in patients with MS would be a crucial step toward better understanding the MS-EBV connection. “If we learn that antivirals are effective in MS, we should develop non-immunosuppressive therapies for patients with MS as soon as possible,” she said.

Stanford University’s Lawrence Steinman, MD, professor of neurology and neurological sciences, pediatrics, and genetics, who coauthored the commentary on the original Science paper, agreed that it’s worth investigating whether antiviral therapies targeting EBV will benefit patients who already have MS. But he cautioned against clinicians experimenting on their own outside of a research study. “You’d want to use the right antiviral and a properly designed trial,” he said.
 

Antivirals May Place a Crucial Role in MS Control

While there are no approved therapies for EBV, several MS disease-modifying therapies have anti-EBV effects, Dr. Levy said, citing anti-CD20 therapy as a clear example. It depletes B cells from the circulation, and it depletes EBV because the virus lives in the B-cell compartment. “Some MS treatments may be inadvertent EBV antivirals,” he said.

Researchers are also thinking about how they might exploit the MS-EBV link to prevent MS from developing in the first place, but there are uncertainties on that front too.

Conceivably, there may be some way to intervene in patients to treat EBV and prevent MS, such as a unique treatment for infectious mononucleosis (IM), Dr. Levy said.

Researchers are especially intrigued by signs that the timing of infection may play a role, with people infected with EBV via IM after early childhood at especially a high risk of developing MS. A 2022 German study calculated that people who developed IM were almost twice as likely as those who didn’t to develop MS within 10 years, although the risks in both groups were very small. Subgroup analysis revealed the strongest association between IM and MS was in the group infected between age 14 and 20 years (hazard ratio, 3.52; 95% CI, 1.00-12.37). They also saw a stronger association in men than in women.

The authors of a 2023 review in Clinical & Translational Immunology wrote that “further understanding of IM may be critical in solving the mystery” of EBV’s role in MS.

Dr. Levy said this line of questioning is important. “In theory, if we can tell who is prone to develop MS or whose immune system might be reacting to EBV to cause MS, we can intervene early to prevent neurological manifestations.”

However, “remember that while most of the world gets EBV infections, only 1 in 1000 will get MS. So, it might not be feasible to test everyone before neurological manifestations occur,” he said.
 

More Questions to Answer About EBV and MS

Researchers hope to answer several questions moving forward. For one, why is EBV uniquely connected to MS? “You would think that if there were cross-reactivity to myelin, there are many viruses that could cause MS. But the association seems to be very restricted to EBV,” Dr. Levy said. “It is probably due to the fact that EBV is one of the only human viruses that can infect B cells, which play important roles in controlling immune responses.”

The molecular mimicry theory also opens up a potential treatment pathway.

A 2022 study reported “high-affinity molecular mimicry between the EBV transcription factor EBV nuclear antigen 1 (EBNA1) and the central nervous system protein glial cell adhesion molecule (GlialCAM)”. Antibodies against EBNA1 and GlialCAM are prevalent in patients with MS. In a mouse model of MS, the researchers showed that EBNA1 immunization exacerbates disease. The authors wrote that “Our results provide a mechanistic link for the association between MS and EBV and could guide the development of new MS therapies.”
 

Could an EBV Vaccine Be the Answer?

On the prevention front, perhaps the most obvious question is whether an EBV vaccine could eliminate MS for good?

Dr. Bebo, from the National MS Society, said it will be important to determine which kind of vaccine is best. Is it one that neutralizes infection with EBV? Or is it enough to simply prevent clinical manifestations?

Both types of vaccines are in development, and at least two clinical trials are now in the works. The National Institute of Allergy and Infectious Diseases is sponsoring a phase 1 study of an adjuvanted EBV gp350-Ferritin nanoparticle vaccine. Forty subjects aged 18-29 years will take part: 20 with EBV and 20 who are not infected. The study is expected to end in 2025.

There is also a phase 1 placebo-controlled study in progress testing an EBV vaccine based on mRNA-1189 in 422 subjects aged 12-30 years. This trial is also due to end in 2025.

“This is very exciting, but it may take a decade or two to determine whether a vaccine is effective at preventing MS,” Dr. Levy said.

The goal is to uncover clues that “can help us understand MS a little bit better and reveal insights that could lead to new disease-modifying therapy,” Bruce Bebo, PhD, executive vice president of research with the National MS Society, said in an interview.
 

EBV Boosts MS Risk 32-Fold

EBV was first linked to MS back in 1981. For the 2022 study, researchers at the Harvard T.H. Chan School of Public Health and Harvard Medical School, Boston, analyzed blood serum from 10 million active-duty members of the US military. They focused on 801 recruits with MS and matched them with more than 1500 controls. All but one of those with MS had been infected with EBV; infection appeared to boost the risk for MS 32-fold (95% CI, 4.3-245.3; P < .001).

Neurologist and associate professor Michael Levy, MD, PhD, of Harvard Medical School and Massachusetts General Hospital, said in an interview that the findings are “groundbreaking” and confirm that EBV is “likely the primary cause of MS.”

According to Dr. Levy, there are two main theories about why EBV causes MS. The first hypothesis, known as the “molecular mimicry” theory, suggests that “EBV is a trigger of MS, possibly when the immune system mistakes a viral protein for a myelin protein and then attacks myelin,” Dr. Levy said. In MS, the immune system attacks the protective myelin sheath and the axons it insulates.

“After that point, the virus is not necessary to maintain the disease state and eradicating the virus likely won’t have much effect since the immune response is already triggered,” he said.

The second theory is that “EBV is a driver of MS where there is an ongoing, lifelong immunological response to EBV that continuously causes damage in the central nervous system [CNS]. In theory, if we could eradicate the virus, the destructive immune response could also resolve. Thus, an EBV antiviral treatment could potentially treat and maybe cure MS,” Dr. Levy explained, noting that “removing the pathogenic antigen may be a more effective strategy than removing the immune response.”

However, “we don’t yet know which hypothesis is correct,” he said. But “there is preliminary evidence in favor of each one.”
 

‘Additional Fuses Must Be Ignited’

It’s also unclear why most people infected with EBV do not develop MS. It appears that “additional fuses must be ignited,” for MS to take hold, according to a commentary accompanying the landmark 2022 study.

“As far as clinical implications, knowing whether a patient has a medical or family history of mononucleosis may be a small clue, a small piece of evidence, to help with diagnosis,” Dr. Bebo said.

He agreed with Dr. Levy that an antiviral could be a promising approach “If the problem in MS is a dysfunctional immune response to EBV.”

Natalia Drosu, MD, PhD, a postdoctoral fellow at Harvard-MIT Biomedical Engineering Center, said that a clinical trial of a non-immunosuppressive antiviral targeting EBV in patients with MS would be a crucial step toward better understanding the MS-EBV connection. “If we learn that antivirals are effective in MS, we should develop non-immunosuppressive therapies for patients with MS as soon as possible,” she said.

Stanford University’s Lawrence Steinman, MD, professor of neurology and neurological sciences, pediatrics, and genetics, who coauthored the commentary on the original Science paper, agreed that it’s worth investigating whether antiviral therapies targeting EBV will benefit patients who already have MS. But he cautioned against clinicians experimenting on their own outside of a research study. “You’d want to use the right antiviral and a properly designed trial,” he said.
 

Antivirals May Place a Crucial Role in MS Control

While there are no approved therapies for EBV, several MS disease-modifying therapies have anti-EBV effects, Dr. Levy said, citing anti-CD20 therapy as a clear example. It depletes B cells from the circulation, and it depletes EBV because the virus lives in the B-cell compartment. “Some MS treatments may be inadvertent EBV antivirals,” he said.

Researchers are also thinking about how they might exploit the MS-EBV link to prevent MS from developing in the first place, but there are uncertainties on that front too.

Conceivably, there may be some way to intervene in patients to treat EBV and prevent MS, such as a unique treatment for infectious mononucleosis (IM), Dr. Levy said.

Researchers are especially intrigued by signs that the timing of infection may play a role, with people infected with EBV via IM after early childhood at especially a high risk of developing MS. A 2022 German study calculated that people who developed IM were almost twice as likely as those who didn’t to develop MS within 10 years, although the risks in both groups were very small. Subgroup analysis revealed the strongest association between IM and MS was in the group infected between age 14 and 20 years (hazard ratio, 3.52; 95% CI, 1.00-12.37). They also saw a stronger association in men than in women.

The authors of a 2023 review in Clinical & Translational Immunology wrote that “further understanding of IM may be critical in solving the mystery” of EBV’s role in MS.

Dr. Levy said this line of questioning is important. “In theory, if we can tell who is prone to develop MS or whose immune system might be reacting to EBV to cause MS, we can intervene early to prevent neurological manifestations.”

However, “remember that while most of the world gets EBV infections, only 1 in 1000 will get MS. So, it might not be feasible to test everyone before neurological manifestations occur,” he said.
 

More Questions to Answer About EBV and MS

Researchers hope to answer several questions moving forward. For one, why is EBV uniquely connected to MS? “You would think that if there were cross-reactivity to myelin, there are many viruses that could cause MS. But the association seems to be very restricted to EBV,” Dr. Levy said. “It is probably due to the fact that EBV is one of the only human viruses that can infect B cells, which play important roles in controlling immune responses.”

The molecular mimicry theory also opens up a potential treatment pathway.

A 2022 study reported “high-affinity molecular mimicry between the EBV transcription factor EBV nuclear antigen 1 (EBNA1) and the central nervous system protein glial cell adhesion molecule (GlialCAM)”. Antibodies against EBNA1 and GlialCAM are prevalent in patients with MS. In a mouse model of MS, the researchers showed that EBNA1 immunization exacerbates disease. The authors wrote that “Our results provide a mechanistic link for the association between MS and EBV and could guide the development of new MS therapies.”
 

Could an EBV Vaccine Be the Answer?

On the prevention front, perhaps the most obvious question is whether an EBV vaccine could eliminate MS for good?

Dr. Bebo, from the National MS Society, said it will be important to determine which kind of vaccine is best. Is it one that neutralizes infection with EBV? Or is it enough to simply prevent clinical manifestations?

Both types of vaccines are in development, and at least two clinical trials are now in the works. The National Institute of Allergy and Infectious Diseases is sponsoring a phase 1 study of an adjuvanted EBV gp350-Ferritin nanoparticle vaccine. Forty subjects aged 18-29 years will take part: 20 with EBV and 20 who are not infected. The study is expected to end in 2025.

There is also a phase 1 placebo-controlled study in progress testing an EBV vaccine based on mRNA-1189 in 422 subjects aged 12-30 years. This trial is also due to end in 2025.

“This is very exciting, but it may take a decade or two to determine whether a vaccine is effective at preventing MS,” Dr. Levy said.

Dr. Levy, Dr. Steinman, Dr. Drosu, and Dr. Bebo had no disclosures.
