Cautionary findings on acquired immunodeficiency from anti-CD20 MS therapy
, Brandi L. Vollmer, MPH, reported online as part of the 2020 American Academy of Neurology Science Highlights.
The hypogammaglobulinemia was preceded by an IgM of 40 mg/dL or less in 35% of cases and was accompanied by concurrent development of low IgM in another 39%, added Ms. Vollmer, a professional research assistant at the Rocky Mountain Multiple Sclerosis Center at Anschutz Medical Campus, University of Colorado, Denver.
She presented a retrospective study of 527 randomly selected MS patients and another 17 with neuromyelitis optica spectrum disorder who averaged 44 years of age and a 9.2-year disease duration upon commencing rituximab (Rituxan) with close laboratory monitoring. Their mean cumulative rituximab dose during a mean 30.2 months of therapy was 3,312 mg. Ninety-six MS patients eventually switched to ocrelizumab (Ocrevus), accumulating a total dose of 1,175 mg of that anti-CD20 humanized monoclonal antibody.
Absolute lymphocyte count dropped to 500 cells/mm3 or lower in 10.4% of patients at a mean of 11.3 months into anti-CD20 therapy. Low immunoglobulins came later: The mean time to onset of low IgM in affected patients was 19.7 months, and hypogammaglobulinemia, as defined by an IgG of 500 mg/dL or less, occurred at a mean of 36.1 months. Higher cumulative doses of anti-CD20 agents were associated with increased likelihood of hypogammaglobulinemia.
Asked to comment on the research findings, neurologist Nida Laurin, MD, said the Colorado study provides helpful insights into the timing of onset of acquired immunodeficiency in patients on B-cell-targeted therapy.
“This paper informs us that we should monitor our patients much closer for signs of hypogammaglobulinemia and lymphopenia starting with year 2 on therapy, and switch treatment when the threshold is reached. I do expect production of gamma globulins and lymphocytes to recover with discontinuation of anti-CD20 therapy, maybe over a period of 6-10 months. It might also recover with lower-dose therapy because the effect on B cells is dose-dependent,” observed Dr. Laurin, an MS specialist at the Banner Health–University Medicine Neuroscience Institute in Phoenix and the University of Arizona in Tucson.
Her colleague Barry Hendin, MD, noted that there is no consensus regarding the best response to all these changes.
“Some clinicians add IVIG, some change therapies, and some observe only,” said Dr. Hendin, a neurologist at Banner Health–University Medical Center, Phoenix, and clinical professor of neurology at the University of Arizona in Tucson.
However, Dr. Laurin asserted that it would be a mistake for physicians and patients to shrug off anti-CD20 therapy–induced lymphopenia in light of studies demonstrating that lymphopenia and older age are two main risk factors for progressive multifocal leukoencephalopathy in patients on disease-modifying therapies.
“More cases of PML can be expected with continuous use of anti-CD20 therapies if lymphopenia is ignored,” she cautioned.
Depressed levels of IgM and IgG have been associated with increased risk of serious infections. In light of the COVID-19 pandemic and the eventual prospect of a vaccine, it is especially important to avoid putting patients with MS in harm’s way via treatment-induced acquired immunodeficiency, Dr. Laurin said.
Ms. Vollmer reported having no financial conflicts regarding her study. Dr. Laurin reported serving as a speaker or consultant for Alexion, Allergan, Biogen, Bristol-Myers Squibb, EMD Serono, Genentech, Lundbeck, and Sanofi Genzyme. Dr. Hendin serves as a consultant to Biogen, Genentech, Genzyme, EMD Serono, Novartis, and Bristol-Myers Squibb.

Five-year siponimod data support early MS treatment
Among and had a lower annualized relapse rate up to 5 years later, compared with patients who initially received placebo and switched to siponimod. This research was presented online as part of the 2020 American Academy of Neurology Science Highlights.
Benefits of siponimod gained during the controlled period were “sustained for up to 5 years, suggesting a continuous effect of siponimod and underlining the advantages of early treatment initiation with siponimod,” the researchers said. Incidence rates of adverse events during the extension study were consistent with those during the controlled treatment period.
The results “highlight the critical importance of early treatment intervention ... to ensure the best possible long-term outcomes for patients with MS who are experiencing progression,” study investigator Bruce Cree, MD, PhD, said in a news release.
“It’s never too early to stay ahead of progression in MS, since the early identification of physical and cognitive changes – even subtle ones – can indicate MS disease progression and therefore allow for timely intervention.” said Dr. Cree, who is clinical research director and George A. Zimmermann Endowed Professor in Multiple Sclerosis at the University of California, San Francisco.
Siponimod, marketed as Mayzent, is a sphingosine 1-phosphate receptor modulator that selectively binds to S1P1 and S1P5 receptors. The oral drug was approved by the Food and Drug Administration in 2019 for the treatment of relapsing forms of MS, including clinically isolated syndrome, relapsing remitting disease, and active secondary progressive disease in adults.
To assess the long-term efficacy and safety of siponimod in patients with secondary progressive MS, Dr. Cree and colleagues analyzed data from patients in the controlled and extension parts of the EXPAND trial. Patients could have had been in the study for as long as 5 years at the data cutoff in April 2019. Efficacy analyses included time to 3-month confirmed disability progression on the Expanded Disability Status Scale (EDSS), time to 6-month confirmed disability progression, time to 6-month confirmed worsening of 4 or more points on the Symbol Digit Modalities Test (SDMT), and annualized relapse rate. In EXPAND, the researchers defined confirmed disability progression as a 1-point increase in EDSS if the baseline score was 3.0-5.0, or a 0.5-point increase if the baseline score was 5.5-6.5.
“Of the 1,224 (74% of 1,651 randomized) patients entering the extension, 878 (72%) were ongoing,” the researchers reported. Patients who received siponimod continuously were less likely to experience 3-month confirmed disability progression and 6-month confirmed disability progression, relative to patients who switched from placebo. In addition, patients who received continuous siponimod treatment had a prolonged time to 6-month confirmed disability progression, compared with patients who switched from placebo. For the 25th percentile of patients, continuous siponimod treatment corresponded to a delay of 54% (21 months vs. 13.6 months). Risk of worsening on the SDMT was reduced by 23% in the continuous siponimod–treatment group. For the 25th percentile of patients, this reduced risk corresponded to a delay of 62% (29.6 months vs. 18.3 months). ARR was 0.054 in the continuous-siponimod group, compared with 0.097 in the group that switched to siponimod from placebo, a reduction of 52%.
Dr. Cree has received personal compensation from Novartis, which markets siponimod, as well as Akili, Alexion, Atara, Biogen, EMD Serono, and TG Therapeutics. His coauthors reported receiving research support and personal compensation from Novartis and other pharmaceutical companies. Several coauthors were Novartis employees.

Report details first case of PML with ocrelizumab alone
The case report was presented online as part of the 2020 American Academy of Neurology Science Highlights.
PML, an opportunistic infection of the brain caused by reactivation of the John Cunningham (JC) virus, has occurred with rituximab, another anti-CD20 therapy, in rare cases. Eight other cases of PML diagnosed after ocrelizumab initiation are considered carry-over cases related to prior treatment with natalizumab or fingolimod, according to Genentech, the manufacturer of ocrelizumab. No other PML cases have been associated with ocrelizumab alone.
The case without prior MS treatment was in a 78-year-old man. He presented with 2 weeks of progressive visual disturbance and confusion, said Marc L. Gordon, MD, chief of neurology at the Zucker Hillside Hospital in Glen Oaks, N.Y., and professor of neurology and psychiatry at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell in Hempstead, N.Y.
The patient had a right homonymous hemianopia. “MRI revealed an enlarging non-enhancing left parietal lesion without mass effect,” reported Dr. Gordon and colleagues. “CSF PCR revealed 1,000 copies/mL of JCV, confirming the diagnosis of PML. Blood work upon diagnosis revealed grade-2 lymphopenia ... and negative HIV serology.”
“The patient’s symptoms progressed over weeks to involve bilateral visual loss, right facial droop, and dysphasia,” they said. “Ocrelizumab was discontinued and off-label pembrolizumab treatment was initiated.” The patient did not respond to therapy and became bedbound, Dr. Gordon said in an interview. The patient received palliative care and died. An autopsy is pending.
“PML occurrence may have been multifactorial, due to a combination of the immunomodulatory function of ocrelizumab, possible immune senescence, and preceding mild lymphopenia,” Dr. Gordon and coauthors said. “This case emphasizes the importance of a thorough discussion of the risks and benefits of ocrelizumab, especially in patients at higher risk for infections, such as the elderly.”
The patient, who was Dr. Gordon’s patient for 20 years, had monitored updates in drug development and had looked forward to starting ocrelizumab, the first therapy approved for primary progressive MS, when it became available after its approval in 2017. The patient was concerned about progressively worsening gait impairment and related falls caused by MS.
Antibodies indicated that the patient had prior exposure to JCV, but Dr. Gordon considered the risk of PML to be relatively small. Prior to treatment, the patient’s absolute lymphocyte count was normal or indicated mild lymphocytopenia, which Dr. Gordon did not consider clinically significant. The patient received ocrelizumab for 2 years without incident.
In an information sheet for health care professionals about ocrelizumab and PML prepared in February 2020, Genentech says the patient’s age and low absolute lymphocyte count are confounding factors, which distort “the assessment of association between exposure to a drug and an adverse event.
“As of January 31, 2020, no unconfounded PML cases associated with ocrelizumab therapy have been reported,” according to the document. “Out of more than 150,000 patients treated globally (clinical trials and post-marketing experience), there have been nine confirmed, confounded cases of PML in patients treated with ocrelizumab, of which eight were carry-over cases from a prior DMT.”
The prescribing information for the drug notes that no cases of PML were identified in ocrelizumab clinical trials, but that PML has been observed in patients treated with other anti-CD20 antibodies and other MS therapies. In addition, PML “has been associated with some risk factors (eg, immunocompromised patients, polytherapy with immunosuppressants).
“At the first sign or symptom suggestive of PML, withhold ocrelizumab and perform an appropriate diagnostic evaluation,” the prescribing information says. “MRI findings may be apparent before clinical signs or symptoms. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes.”
“It is important for people to recognize that this is at least a possibility,” Dr. Gordon said. Any change in clinical symptomatology may warrant imaging, and CSF testing may be warranted if an MRI raises concerns about PML, he said.
Dr. Gordon has received research support from MSD (Merck), Eisai, AbbVie, and Janssen.

In an information sheet for health care professionals about ocrelizumab and PML prepared in February 2020, Genentech says the patient’s age and low absolute lymphocyte count are confounding factors, which distort “the assessment of association between exposure to a drug and an adverse event.
“As of January 31, 2020, no unconfounded PML cases associated with ocrelizumab therapy have been reported,” according to the document. “Out of more than 150,000 patients treated globally (clinical trials and post-marketing experience), there have been nine confirmed, confounded cases of PML in patients treated with ocrelizumab, of which eight were carry-over cases from a prior DMT.”
The prescribing information for the drug notes that no cases of PML were identified in ocrelizumab clinical trials, but that PML has been observed in patients treated with other anti-CD20 antibodies and other MS therapies. In addition, PML “has been associated with some risk factors (eg, immunocompromised patients, polytherapy with immunosuppressants).
“At the first sign or symptom suggestive of PML, withhold ocrelizumab and perform an appropriate diagnostic evaluation,” the prescribing information says. “MRI findings may be apparent before clinical signs or symptoms. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes.”
“It is important for people to recognize that this is at least a possibility,” Dr. Gordon said. Any change in clinical symptomatology may warrant imaging, and CSF testing may be warranted if an MRI raises concerns about PML, he said.
Dr. Gordon has received research support from MSD (Merck), Eisai, AbbVie, and Janssen.

Database will collect data on COVID-19 in patients with MS
The COViMS (COVID-19 Infections in Multiple Sclerosis and Related Diseases) database is gathering information from patients throughout the United States and will soon gain access to Canadian data. Data from patients with CNS demyelinating diseases such as neuromyelitis optica and myelin oligodendrocyte glycoprotein antibody diseases also will be included in COViMS. Amber Salter, PhD, MPH, the director of the North American Research Committee on MS (NARCOMS) is supervising the data collection and analyses.
“COViMS will provide valuable insight on how COVID-19 affects people with MS, including if certain disease-modifying treatments incur special risks,” said June Halper, CEO of CMSC, in a press release.
The project began when CMSC and NMSS established independent registries of epidemiologic data related to MS and COVID-19. The two groups soon began communicating and included other researchers, who also were considering establishing registries, in their discussions. In addition, representatives of the Cleveland Clinic verbally agreed to share data that they have been collecting with the COViMS registry. “The fast-moving, almost parallel, efforts led to this collaboration,” said Gary Cutter, PhD, professor of biostatistics at the University of Alabama at Birmingham. “This in itself is noteworthy because all of this took place within an incredibly short time from inception to the initiation of data collection.”
The effects of SARS-CoV-2 infection on the health of patients with MS is little understood. In North America, no reporting system had been organized to gather information on these patients and track outcomes. Such a system could influence the treatment of people with MS who become infected with the novel coronavirus or other similar future viruses. The COViMS registry is intended to define the impact of COVID-19 on patients with MS and ascertain how factors such as age, comorbidities, and MS treatments affect outcomes of COVID-19. “The estimated median age of MS patients in the U.S. is about 52 years, thus putting many at increased risk just due to age,” said Dr. Cutter.
“People with MS and their health care providers need evidence-based guidance to provide optimal MS care during the COVID-19 pandemic, and the COViMS database will help answer the many pressing questions,” said Bruce Bebo, executive vice president of research for the NMSS, in a press release.
The two organizations encourage neurologists and other health care providers who treat patients with MS and documented COVID-19 infection to complete a Case Report Form on the COViMS website, which includes answers to frequently asked questions, a sample CRF, and other resources. The website will provide real-time data once registry participation is underway.

FDA removes pregnancy category C warning from certain MS medications
The FDA based the decision on data from more than 1,000 real-world pregnancies, including pregnancies from a large epidemiologic study and published studies over several decades, which found no connection between use of interferon-beta products during early pregnancy and an increased risk of major birth defects, according to the FDA.
As a result, the labels for both medications will no longer have the pregnancy category C designation; however, patients should continue to notify their health care provider if they are pregnant or plan to become pregnant.
The FDA decision to remove the warning follows a similar decision by the European Medicines Agency last year.
“Many women with MS are diagnosed during their childbearing years. With this important update for Plegridy and Avonex, healthcare providers have more data to inform appropriate treatment paths for patients who may be pregnant or planning for pregnancy,” said Bernd Kieseier, MD, MHBA, executive director and head of global MS at Worldwide Medical, Biogen, in a press release.

FDA approves ozanimod for relapsing and secondary progressive forms of MS
The Food and Drug Administration has approved the oral medication ozanimod (Zeposia) for relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, according to a release from Bristol-Myers Squibb.
Ozanimod is a sphingosine 1-phosphate (S1P) receptor modulator that binds with high affinity to S1P receptors 1 and 5. It blocks the capacity of lymphocytes to egress from lymph nodes, reducing the number of lymphocytes in peripheral blood. Although its therapeutic mechanism of action in MS is unknown, it may involve the reduction of lymphocyte migration into the central nervous system. A genetic test is not required to start the drug, and no patient observation is required for the first dose, although up-titration of initial doses are required to reach the maintenance dose because a transient decrease in heart rate and atrioventricular conduction delays may occur, according to the company.
The approval is based on a pair of head-to-head studies that compared it with interferon beta-1a (Avonex) and together included more than 2,600 patients. It delivered better efficacy in terms of relative reduction in annualized relapse rate (48% at 1 year and 38% at 2 years). It also demonstrated better relative reduction of the number of T1-weighted gadolinium-enhanced brain lesions (63% fewer at 1 year and 53% fewer at 2 years) and number of new or enlarging T2 lesions (48% fewer at 1 year and 42% at 2 years).
Ozanimod is contraindicated in patients who, in the past 6 months, experienced a myocardial infarction, unstable angina, stroke, or other conditions. It is associated with other health risks, including infections, liver injury, additive immunosuppressive effects from prior immune-modulating therapies, and increased blood pressure. Certain assessments, such as recent complete blood count, ECG, liver function test, and current and prior medications and vaccinations, are required before initiation of treatment.
In its announcement, Bristol-Myers Squibb said that it has decided to delay the commercial launch of ozanimod during the COVID-19 pandemic until a later date.
The drug is also in development for additional immune-inflammatory indications, including ulcerative colitis and Crohn’s disease.
The full prescribing information can be found on the company’s website.

Teriflunomide increases the likelihood of achieving NEDA in relapsing-remitting MS
WEST PALM BEACH, FLA. – , according to an analysis presented at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis. Teriflunomide reduces the risks of relapse, relapse resulting in hospital admission, and relapse resulting in prolonged hospitalization, compared with placebo.
Teriflunomide modulates the immune system and is an approved treatment for relapsing-remitting MS and clinically isolated syndrome. The phase 3 TEMSO study provided evidence that established the treatment’s safety and efficacy. In that study, significantly more patients who received a 14-mg dose of teriflunomide achieved NEDA, compared with patients who received placebo. Researchers generally weight all components of NEDA (i.e., confirmed disability worsening [CDW], relapse, and unique active MRI lesions) equally, but this approach could limit the interpretation of how each endpoint contributes to the effectiveness of a disease-modifying therapy.
A new analysis of TEMSO data
Keith R. Edwards, MD, director of the MS Center of Northeastern New York in Latham and colleagues conducted a win ratio matched-pairs analysis of TEMSO data to evaluate the efficacy of teriflunomide in enabling patients to achieve NEDA. In this analysis, the components of NEDA were assessed in order of priority, rather than as factors of equal weight.
In TEMSO, patients with relapsing-remitting MS received placebo or 14 mg of teriflunomide for 108 weeks. Dr. Edwards and colleagues matched active and control patients according to baseline characteristics. They compared the occurrence of disease activity events between the members of each pair. If a patient receiving teriflunomide had an event later than a control did, or did not have the event at all, teriflunomide was considered to “win.” If neither patient in a pair had a given event, the researchers omitted the pair from their analysis. Dr. Edwards and colleagues counted wins and summarized them as ratios. They conducted a second win ratio analysis of all relapses and relapses resulting in deaths, life-threatening events, prolonged hospitalizations, and hospital admissions.
NEDA components were ranked and assessed in the following order of decreasing priority: CDW, relapse, unique active MRI lesions. In a sensitivity analysis, the investigators ranked and assessed these components in the reverse order.
Sensitivity analysis supported primary analysis
Dr. Edwards and colleagues included 363 participants who received placebo and 358 who received teriflunomide in their analysis. Baseline characteristics did not differ significantly between the two groups. The population’s mean age was approximately 38 years, and about 73% of participants were female. The population’s mean baseline Expanded Disability Status Scale score was 2.7. Overall, about 72% of participants completed the study.
The researchers created 321 risk-matched pairs of participants. The win ratio analysis indicated that patients who received teriflunomide were significantly more likely to achieve NEDA, compared with controls (win ratio, 1.33). When the investigators analyzed the data by prioritizing the NEDA components in the reverse order, they found similar results (win ratio, 1.41).
When Dr. Edwards and colleagues analyzed relapse severity, they found that no relapses resulting in death or life-threatening events occurred in the active or control groups. Compared with placebo, teriflunomide significantly reduced the risk of relapse, relapses resulting in hospital admissions, and relapses resulting in prolonged hospitalizations (win ratio, 1.37).
The TEMSO study was funded by Sanofi. Dr. Edwards received grant or research support from Biogen, Genentech, Genzyme, and Novartis. Several authors received funding from Sanofi.

REPORTING FROM ACTRIMS Forum 2020
Manual dexterity may decline more rapidly in pediatric-onset MS
WEST PALM BEACH, FLA. – (AOMS), according to an analysis presented at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.
When MS onset occurs before the patient is age 18 years, the patient is considered to have POMS. Compared with AOMS, POMS is less prevalent and has distinct features. To determine whether changes in physical performance differ between POMS and AOMS, Sarah M. Planchon, PhD, a project scientist at the Mellen Center for MS at the Cleveland Clinic, and colleagues analyzed data cut 9 from the MS PATHS (MS Partners Advancing Technology and Health Solutions) initiative. As part of this initiative, which is sponsored by Biogen, investigators collect MS performance measures longitudinally at each patient visit. Among these measures are the manual dexterity test (MDT), an iPad version of the Nine-Hole Peg Test, and the walking speed test (WST), which is the iPad version of the Timed 25-Foot Walk.
Dr. Planchon and colleagues matched each patient with POMS to five patients with AOMS according to disease duration. They calculated descriptive statistics for the sample and performed Tukey’s honestly significant difference test to compare patient groups on several categorical variables.
Overall, function was better in POMS than in AOMS
The investigators included 3 years’ worth of data from 6,457 patients in their analysis. The average age was approximately 50 years for patients with AOMS and 31 years for patients with POMS. The time elapsed since diagnosis was approximately 14 years in the AOMS group and 17 years in the POMS group. The proportion of female patients was about 74% in the AOMS group and 73% in the POMS group. Compared with the AOMS group, the POMS group had higher proportions of patients who were Asian (0.5% vs 2.6%), black (9.3% vs 11.5%), and other race (2.8% vs 9.3%).
Overall, patients with POMS performed better than patients with AOMS by 1.39 seconds on the MDT and by 0.79 seconds on the WST. Regression analyses indicated that with increasing age, patients with AOMS declined more quickly on the MDT and the WST than patients with POMS did. When the investigators stratified the results by disease duration, however, patients with POMS declined more rapidly on the MDT than did patients with AOMS. There was no significant difference between groups in WST in this analysis. When Dr. Planchon and colleagues performed linear regression and adjusted for variables such as age, sex, race, education, insurance, employment, MS phenotype, disease duration, number of relapses, and Patient-Determined Disease Steps (PDDS), the MS onset type did not significantly affect outcomes. Age, sex, PDDS, and MS type were significant covariates for both tests.
The role of occupational and physical therapy
“POMS patients tend to have a greater dysfunction of the cerebellar and brainstem regions of the brain, both of which may impact motor skills to a greater degree than other regions of the brain,” said Dr. Planchon. The increased rate of manual impairment in POMS, compared with AOMS, does not necessarily indicate more severe disease, she added. Getting a true picture of disease severity would require consideration of factors such as ambulation, cognitive functioning, vision, fatigue, and depression.
“We would recommend introducing POMS patients to occupational and physical therapy early in their disease course, before significant deficits accrue,” said Dr. Planchon. “Early familiarity with rehabilitation services should help the patient and family optimize what exercises are being done to improve and maintain function.”
The optimal pharmacologic treatment for POMS is unknown. One therapy (i.e., fingolimod) has Food and Drug Administration approval, and clinical trials of other treatments are ongoing. Some MS treatments not indicated for a pediatric population are used off label in children.
“We plan to delve deeper into the data set, including using regression modeling to try to better define differences between individuals with POMS and AOMS that may lead to the functional outcome changes we have already observed,” said Dr. Planchon. “We also plan to investigate further the impact of POMS on cognition and quality of life measures and to better understand disease-modifying therapy prescribing patterns and benefits in individuals with POMS. We will look for associations in the MRI imaging findings and various biomarkers to help us understand the disease process in this special population of MS.”
Dr. Planchon has received research support from the Guthy-Jackson Charitable Foundation. Her coinvestigators received funding from Biogen, Genentech, Genzyme, MedImmune, Novartis, Serono, and Teva.

When MS onset occurs before the patient is age 18 years, the patient is considered to have POMS. Compared with AOMS, POMS is less prevalent and has distinct features. To determine whether changes in physical performance differ between POMS and AOMS, Sarah M. Planchon, PhD, a project scientist at the Mellen Center for MS at the Cleveland Clinic, and colleagues analyzed data cut 9 from the MS PATHS (MS Partners Advancing Technology and Health Solutions) initiative. As part of this initiative, which is sponsored by Biogen, investigators collect MS performance measures longitudinally at each patient visit. Among these measures are the manual dexterity test (MDT), an iPad version of the Nine-Hole Peg Test, and the walking speed test (WST), which is the iPad version of the Timed 25-Foot Walk.
Dr. Planchon and colleagues matched each patient with POMS to five patients with AOMS according to disease duration. They calculated descriptive statistics for the sample and performed Tukey’s honestly significant difference test to compare patient groups on several categorical variables.
Overall, function was better in POMS than in AOMS
The investigators included 3 years’ worth of data from 6,457 patients in their analysis. The average age was approximately 50 years for patients with AOMS and 31 years for patients with POMS. The time elapsed since diagnosis was approximately 14 years in the AOMS group and 17 years in the POMS group. The proportion of female patients was about 74% in the AOMS group and 73% in the POMS group. Compared with the AOMS group, the POMS group had higher proportions of patients who were Asian (0.5% vs 2.6%), black (9.3% vs 11.5%), and other race (2.8% vs 9.3%).
Overall, patients with POMS performed better than patients with AOMS by 1.39 seconds on the MDT and by 0.79 seconds on the WST. Regression analyses indicated that with increasing age, patients with AOMS declined more quickly on the MDT and the WST than patients with POMS did. When the investigators stratified the results by disease duration, however, patients with POMS declined more rapidly on the MDT than did patients with AOMS. There was no significant difference between groups in WST in this analysis. When Dr. Planchon and colleagues performed linear regression and adjusted for variables such as age, sex, race, education, insurance, employment, MS phenotype, disease duration, number of relapses, and Patient-Determined Disease Steps (PDDS), the MS onset type did not significantly affect outcomes. Age, sex, PDDS, and MS type were significant covariates for both tests.
The role of occupational and physical therapy
“POMS patients tend to have a greater dysfunction of the cerebellar and brainstem regions of the brain, both of which may impact motor skills to a greater degree than other regions of the brain,” said Dr. Planchon. The increased rate of manual impairment in POMS, compared with AOMS, does not necessarily indicate more severe disease, she added. Getting a true picture of disease severity would require consideration of factors such as ambulation, cognitive functioning, vision, fatigue, and depression.
“We would recommend introducing POMS patients to occupational and physical therapy early in their disease course, before significant deficits accrue,” said Dr. Planchon. “Early familiarity with rehabilitation services should help the patient and family optimize what exercises are being done to improve and maintain function.”
The optimal pharmacologic treatment for POMS is unknown. One therapy (i.e., fingolimod) has Food and Drug Administration approval, and clinical trials of other treatments are ongoing. Some MS treatments not indicated for a pediatric population are used off label in children.
“We plan to delve deeper into the data set, including using regression modeling to try to better define differences between individuals with POMS and AOMS that may lead to the functional outcome changes we have already observed,” said Dr. Planchon. “We also plan to investigate further the impact of POMS on cognition and quality of life measures and to better understand disease-modifying therapy prescribing patterns and benefits in individuals with POMS. We will look for associations in the MRI imaging findings and various biomarkers to help us understand the disease process in this special population of MS.”

DMT use is common in older patients with MS
WEST PALM BEACH, FLA. –
MS disease activity typically declines with age. At the same time, evidence to support the efficacy of MS drugs in older patients is limited, said Yinan Zhang, MD, a researcher at Icahn School of Medicine at Mount Sinai, New York. Clinical trials have tended to enroll younger patients and to include only patients with active disease, which is not representative of most older patients in the real world, Dr. Zhang said.
“DMTs for MS may be less efficacious in the elderly, especially in the absence of active disease, yet real-world prescribing patterns still show widespread use of DMTs in older patients,” Dr. Zhang and colleagues said. Physicians may be able to use the presence of disease activity to identify older patients who should receive therapy. “Continuing DMTs in elderly patients who have no evidence of disease activity should be questioned rather than accepted,” they said at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.
To investigate whether age affects the efficacy of DMTs in patients with relapsing-remitting MS and how often DMTs are used in different age groups, Dr. Zhang and coinvestigators conducted a meta-analysis of group-level data from clinical trial, analyzed individual-level data from one of the trials, and reviewed survey data from two registries.
The meta-analysis included 26 clinical trials of 13 DMTs with more than 12,400 patients. Participants had an average age of about 37 years. “An age-dependent relationship of DMTs on relapse rate in RRMS [relapsing-remitting MS] cannot be established with currently published aggregate summary data,” the researchers said. “The meta-analysis was limited by the use of group-level data resulting in a narrow range of mean age.”
In an effort to overcome the limitations of group-level data, they analyzed individual-level data from approximately 1,000 patients in the CombiRx trial, which compared interferon beta-1a plus glatiramer acetate versus the agents alone. Thirty-seven of the patients were aged 55 years or older. The results suggest that each “1-year increase in baseline age was associated with a 3.2% reduction in the odds of having a relapse” during the trial, the investigators said. Change in annualized relapse rate was not significantly associated with age group, which may have resulted from “enrollment criteria selecting for patients with active disease, where DMTs are expected to show the greatest efficacy,” the researchers said.
Finally, Dr. Zhang and colleagues reviewed data on DMT use by age group from the North American Research Committee on Multiple Sclerosis (NARCOMS) and the Multiple Sclerosis Surveillance Registry (MSSR) from Veterans Affairs. In a 2018 survey of nearly 7,000 patients in the NARCOMS registry, 39.2% of patients older than 60 years were taking a DMT, including 44.5% of patients aged 61-70, 28.6% of patients aged 71-80, and 11% of patients aged 81 years and older. In comparison, about 62% of patients aged 41-50 years were taking DMT.
A 2019 survey of about 1,700 veterans in the MSSR found that 36.3% of patients older than 60 years were taking a DMT, including 41.1% of patients aged 61-70, 27.2% of patients aged 71-80, and 7.1% of patients aged 81 years and older. Among patients aged 41-50 years, more than 72% were taking a DMT. “The continued use of DMTs in the elderly may be the result of the perceived notion that disease inactivity is due to the effect of DMTs rather than the natural disease course with aging,” they said.
Dr. Zhang had no relevant disclosures. Coauthors disclosed consulting for and grant support from various pharmaceutical companies.

Serum GFAP may indicate disease severity in NMOSD
WEST PALM BEACH, FLA. – (NMOSD), according to research presented at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis. Treatment with inebilizumab decreases serum GFAP concentrations and reduces the risk of an NMOSD attack, the investigators said.
In NMOSD, autoantibodies often target aquaporin-4, a protein expressed on astrocytes. This immune response destroys astrocytes and increases levels of GFAP in cerebrospinal fluid and serum. In the N-MOmentum trial, inebilizumab reduced the risk of attacks by 73%, compared with placebo, in patients with NMOSD. Bruce Cree, MD, PhD, professor of neurology at the University of California, San Francisco, Weill Institute for Neurosciences and colleagues analyzed the data from this trial to examine the relationship between serum GFAP concentrations and disease activity.
In the study, the investigators prospectively collected 1,260 serum samples from 215 participants, 25 healthy donors, and 23 patients with relapsing-remitting multiple sclerosis (MS). Serum GFAP concentration was measured using a single-molecule array assay. The researchers and an independent adjudication committee evaluated attacks during the 28-week randomized controlled study period using predefined criteria.
The median serum GFAP concentration was higher in patients with NMOSD (128.3 pg/mL) than in patients with relapsing-remitting MS (97.5 pg/mL) and healthy controls (73.3 pg/mL). At baseline, 29% of patients with NMOSD and 9% of patients with MS had a serum GFAP concentration that was three or more standard deviations above the mean level in healthy donors.
During the study, patients with a high baseline concentration of serum GFAP were three times more likely to have an adjudicated NMOSD attack than patients with lower serum GFAP concentrations. Concentrations of serum GFAP increased within 1 week of an adjudicated attack during the randomized controlled period. Furthermore, serum GFAP concentration was significantly higher in patients with major adjudicated attacks, compared with those who had minor adjudicated attacks. This finding was true for all organ domains, including for attacks that affected only the optic nerve.
Compared with placebo, inebilizumab reduced the risk of an adjudicated attack by 79% in patients with a normal baseline serum GFAP concentration and by 61% in patients with an elevated baseline serum GFAP concentration. The increase in serum GFAP concentration following an adjudicated attack was significant in patients receiving placebo, but not in patients receiving inebilizumab. Seven samples taken during an adjudicated attack from patients receiving inebilizumab had serum GFAP concentrations within the normal range. One sample taken during an attack from a patient receiving placebo had a serum GFAP concentration within the normal range. In addition, serum GFAP concentrations decreased from baseline among patients receiving inebilizumab who did not have an adjudicated attack.
“These observations suggest that serum GFAP could be a clinically useful biomarker of disease activity and increased attack risk in NMOSD,” said Dr. Cree and colleagues.
