‘Strikingly positive’ effect of novel MS agent
AURORA, COLO. –
“We should be very excited about these results, which are better than expected and fundamentally tackle autoimmunity,” said study investigator Gavin Giovannoni, MD, PhD, chair of neurology at the Blizard Institute of Barts, London, and the London School of Medicine and Dentistry. “It will be interesting to see if this treatment reestablishes immune tolerance and induces long-term remission,” he said.
The late-breaking study was presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.
Significant lesion reduction
With a variety of disease-modifying therapies available for MS, frexalimab would be unique as a novel second-generation monoclonal antibody designed to block the costimulatory CD40/CD40L cellular pathway. Importantly, the mechanism is believed to potentially modify T- and B-cell activation and innate immune cell function, for an effect of reducing inflammation without depleting B cells.
To investigate the drug’s efficacy and safety, Dr. Giovannoni and his colleagues conducted the phase 2, multicenter trial, in which 129 participants with relapsing MS were randomized to one of four groups – high-dose frexalimab (n = 52); low-dose frexalimab (n = 51); or placebo (n = 12 high-dose, n = 14 low-dose), for the 12-week placebo-controlled period, followed by an open-label extension period that is currently ongoing.
Among 125 participants who completed the study’s 12-week double-blind period, those receiving high-dose frexalimab had an 89% greater reduction in the number of new gadolinium-enhancing T1-lesions, compared with the pooled placebo group (P = .0004), meeting the study’s primary endpoint. After 24 weeks, as many as 96% of those in the high-dose frexalimab arm were free of gadolinium-enhanced T1 lesions.
The frexalimab low-dose group also had a lower, but significant, reduction in the number of new gadolinium-enhanced T1-lesions of 79% versus the pooled placebo group (P = .0021).
Both of the frexalimab groups also had reductions in enlarging T2-lesions and total gadolinium-enhanced T1-lesions.
In the high-dose group, data on 38 participants with open-label data from week 37 showed no new gadolinium-enhanced lesions.
In terms of safety, frexalimab was well tolerated over the 12-week study, with headache and COVID-19 reported among 4% or fewer participants. No serious adverse events were reported.
Looking ahead at safety, Dr. Giovannoni noted that “a known unknown is infections, but this is a problem with all therapies that work via immunosuppressive mechanisms, not only therapies targeting CD40L.” That said, “we didn’t see a big infection signal in the trial, which is reassuring. It also shows the immune system has built-in redundancy and many mechanisms to fight infections,” he added.
In his newsletter, Dr. Giovannoni characterized the study’s results as “strikingly positive,” adding that they “are the most exciting to emerge in MS in the last 12-24 months.”
Overall, “these are the first randomized controlled phase 2 data for a CD40L inhibitor in MS and indicate potential for further development of frexalimab as a high-efficacy therapy,” the investigators noted. “Frexalimab led to a pronounced reduction of new gadolinium-enhancing lesions by 3 months and was well-tolerated,” they added.
An intriguing mechanism
Commenting on the study, Salim Chahin, MD, an assistant professor of neurology in the John L. Trotter MS Center in the department of neurology at Washington University, St. Louis, said that frexalimab represents an intriguing mechanistic approach to MS.
“In the world of MS and neuroimmunology, this is indeed a unique mechanism that has not been explored before,” Dr. Chahin said.
“Therapies targeting CD40 and CD40L are not new but were previously associated with unfavorable side effects, mainly thromboembolic events that halted their development,” he said, noting that the drug appears to avoid these side effects, providing good phase 2 efficacy data.
Dr. Chahin agreed that the phase 3 data will be watched closely for further safety and efficacy issues. “Indeed, it is difficult to interpret the occurrence of COVID-19 infections, given the timing of the phase 2 study, or their severity, but based on the mechanism of action, it is possible that this drug will be associated with a more favorable safety profile than some of the currently approved MS treatments,” Dr. Chahin said.
“But phase 3 trial data are much needed to clarify the immunosuppressive risk.”

MS relapse rates similar between anti-CD20 mAbs and switching to fumarates
DENVER – according to a retrospective study presented at the annual meeting of the Consortium of Multiple Sclerosis Centers. Those who switched did, however, experience a lower rate of inpatient infection-related health care visits per year than those who continued anti-CD20 mAbs.
“As MS is a chronic disease requiring long-term treatment, switching between disease-modifying therapies [DMTs] is a common clinical strategy to optimize individual patient outcomes,” lead author Aliza Ben-Zacharia, PhD, DNP, RN, an assistant professor at the Phillips School of Nursing at Mount Sinai and Hunter College, both in New York, and colleagues reported. They noted that anti-CD20 mAbs are considered high-efficacy DMTs while fumarates are considered moderate-efficacy DMTs.
The researchers used data from the Komodo Health Sentinel Claims Database to track and compare 108 patients who were clinically stable on anti-CD20 mAbs and then switched to fumarates with 540 patients who remained on anti-CD20 mAbs for a follow-up period of approximately 1 year.
The study included adults with a diagnosis of MS between January 2015 and August 2022, and only those with a gap of no more than 9 months between anti-CD20 mAbs and fumarates were included as switchers. The researchers also required that switchers had not had any relapses in the previous year on anti-CD20 mAbs before switching, and had to have been on fumarates for at least 3 months after switching.
Women made up 70% of both groups, and both had an average age of 49 years. The racial/ethnic demographics were similar in both groups, and the average MS severity score was 5.5 in the switching group and 5.6 in the staying group. Most patients had been taking or remained on ocrelizumab (93.5%) with a smaller proportion on rituximab (5.6%). Just over a third of those who switched therapy took diroximel fumarate while 64% took dimethyl fumarate.
The researchers noted that patients who stayed on anti-CD20 mAbs had “slightly higher use of other mAbs prior to anti-CD20 mAbs.” Further, “a higher proportion of patients were DMT naive prior to anti-CD20 mAb initiation, compared with those in the switchers group.”
Patients who switched had been on anti-CD20 mAbs an average 730 days before switching to fumarates, and the average time between their last anti-CD20 mAbs dose and starting fumarates was 274 days. Average exposure to fumarates was 341 days.
The 10.2% of patients who relapsed during follow-up after switching to fumarates was not significantly statistically different than the 6.7% of patients who relapsed while remaining on anti-CD20 mAbs (P = .17). A relapse was considered “an MS-related inpatient claim with a primary diagnosis of MS or an outpatient MS-related diagnosis and a prescription claim for an intravenous steroid, adrenocorticotropic hormone, total plasma exchange, or a high-dose oral corticosteroid 7 days or sooner after the outpatient visit,” the researchers explained. The researchers could not track mild relapses that didn’t involve a health care interaction.
There was also no significant difference in overall average health care encounters between those who switched (7.85 encounters) and those who stayed (8.08; P = .57). Further, average health care costs were statistically similar between those who switched ($22,512) and those who stayed ($20,634; P = 0.59).
The likelihood of having more than one infection-related health care encounter was greater for those who remained on anti-CD20 mAbs, but the difference was not statistically significant. The annual rate of infection-related health care encounters was also not statistically different for outpatient and ED visits, but those who switched did have a statistically lower rate of annual infection-related inpatient visits (P = .03).
Among those who switched, 2.8% were hospitalized for infections, compared with 6.5% who stayed on anti-CD20 mAbs. Urinary tract infections, sepsis, and Escherichia coli were the most common infections among those who switched to fumarates, compared with COVID-19, sepsis, and pneumonia, among those who stayed on anti-CD20 mAbs.
The research was sponsored by and funded by Biogen. Six of the authors are Biogen employees who hold stock options in the company. The other three authors reported combined consulting fees from Biogen, EMD Serono, Greenwich Biosciences, TG Therapeutics, Bristol-Myers Squibb, Horizon, and Novartis; research funding from Genentech and Novartis; and stock options in Pfizer.

Shingles infection rates higher in patients with MS
DENVER – , according to research presented at the annual meeting of the Consortium of Multiple Sclerosis Centers. “Herpes zoster and its complications are associated with increased health care cost and decreased quality of life,” lead author Nikita Stempniewicz, MSc, director of U.S. Health Outcomes & Epidemiology at GSK Vaccines, Alexandria, Va., reported.
“The take-home finding is that herpes zoster incidence is high among people with MS overall,” Mr. Stempniewicz said in an interview. “We also found that herpes zoster incidence is numerically higher among MS patients with higher levels of baseline immunosuppression, so another conclusion is that herpes zoster prevention may be warranted among this population given the high level of immunosuppression and the high risk of developing herpes zoster infection.” GSK manufactures Shingrix, the only currently approved and recommended herpes zoster vaccine available in the United States
Lawrence Steinman, MD, a professor of neurology and neurological sciences, pediatrics, and genetics at Stanford (Calif.) Medicine, was not involved in the research but said in an interview that the findings “raise the issue of whether not enough individuals with MS are getting Shingrix, and also whether there is a need for rapid intervention with an antiviral, for those individuals who develop shingles.”
Real-world data
For the study, researchers analyzed U.S. administrative claims data from the Optum Research Database between October 2015 and March 2022 to compare shingles infections between adults with MS (and no other immunocompromising conditions) and a random sample of one million people without any immunocompromising conditions. The study excluded anyone who had been vaccinated against herpes zoster or diagnosed with it in the year before October 2015.
Among the 42,185 adults with MS included in the cohort, just over half (53%) were commercially insured, and 47% had Medicare Advantage. Their average age was 53, and 75% were female. Just over half the cohort (55%) had no immunosuppression because of medications while 35% had low immunosuppression from MS therapy and 10% had high immunosuppression from therapy. High suppression meant patients were taking fingolimod, siponimod, ozanimod, ponesimod, cladribine, or a monoclonal antibody except natalizumab. Those with low suppression were taking natalizumab, fumarates, IVIG, glatiramer acetate, interferon beta or a related drug, teriflunomide, azathioprine, methotrexate, or mycophenolate mofetil.
The rate of shingles infections in the MS patient population was 13.8 per 1,000 people per year, compared with 5.6 infections per 1,000 immunocompetent people per year (adjusted incident rate ratio, 1.69; 95% confidenceinterval, 1.58-1.81. When broken down by age, younger adults aged 18-49 with MS were more than three times more likely to develop shingles (incidence rate, 11.6 per 1,000 people per year) than immunocompetent younger adults (IR, 3.5). The gap was narrower for those age 50 and older, where adults with MS had a rate of 15.2 infections per 1,000 people per year versus 8.6 per 1,000 immunocompetent people per year.
Although MS patients with a higher baseline level of immunosuppression from therapy had higher herpes zoster infection rates (18 cases per 1,000 people per year) than those with low immunosuppression (14 cases per 1,000 people per year) or no immunosuppression from medication (13 cases per 1,000 people per year), rates for all three remained higher than for the immunocompetent population.
Herpes and MS: Some questions still unanswered
“We’ve known that herpes zoster is more common in people with MS, and we’ve known that it is seen in people on MS therapies,” Robert Fox, MD, a staff neurologist at the Mellen Center for MS and vice-chair for research at the Neurological Institute at the Cleveland Clinic, said in an interview. “What we haven’t known is just how much more common it is in people with MS than the rest of the adult population and whether it truly is more common in people taking MS therapies than people not taking MS therapies. This study puts real, population-based numbers on the incidence rates.”
Dr. Fox, who was not involved in the research, noted that a limitation of the study was the inability to know the risk of shingles according to specific MS therapies since all the therapies were grouped together.
”So I can’t say to a patient that their particular therapy increases their risk,” Dr. Fox said. “Similarly with the MS therapies listed in the ‘high’ immunosuppression category: We don’t know that each of the therapies listed do in fact increase the rate of herpes zoster. We just know that the group of MS therapies bunched into the ‘high’ category, on the whole, increase the rate of herpes zoster.”
The study does not provide any information about the impact of Shingrix vaccination, he added, since vaccinated individuals were excluded from the analysis.
Timing the vaccination with MS therapy
Dr. Steinman said in an interview that he recommends herpes zoster vaccination to his patients with MS.
“The mistake that people make with MS is that they don’t want to take the [herpes zoster] vaccine, and they should be taking it,”
Dr. Steinman said. “In a perfect world, they would get it before they went on their [immunosuppressive] drug. But now we’ll have a lot of people who didn’t take the vaccine; they can get it while they’re on their drug.” Although it depends on the particular therapy they’re taking, Dr. Steinman said that most people can get the shingles vaccine while continuing their medication.
The Centers for Disease Control and Prevention recommends that adults who are or will be immunodeficient or immunosuppressed because of a disease or therapy get two doses of the Shingrix vaccine against herpes zoster, regardless of whether they have previously been vaccinated with Zostavax or have ever had shingles. The agency has also issued detailed clinical guidance regarding how to administer the vaccine to individuals taking immunosuppressive therapy, including the option to administer the second dose 1-2 months after the first instead of 2-6 months to “facilitate avoiding vaccination during periods of more intense immunosuppression,” the agency wrote.
The research was sponsored, funded, and analyzed by GSK, which manufactures the shingles vaccine Shingrix, and Mr. Stempniewicz is a GSK employee. Two other authors are GSK employees, and three authors are employees of Optum who received fees from GSK for this study. Dr. Steinman and Dr. Fox reported no relevant disclosures.
DENVER – , according to research presented at the annual meeting of the Consortium of Multiple Sclerosis Centers. “Herpes zoster and its complications are associated with increased health care cost and decreased quality of life,” lead author Nikita Stempniewicz, MSc, director of U.S. Health Outcomes & Epidemiology at GSK Vaccines, Alexandria, Va., reported.
“The take-home finding is that herpes zoster incidence is high among people with MS overall,” Mr. Stempniewicz said in an interview. “We also found that herpes zoster incidence is numerically higher among MS patients with higher levels of baseline immunosuppression, so another conclusion is that herpes zoster prevention may be warranted among this population given the high level of immunosuppression and the high risk of developing herpes zoster infection.” GSK manufactures Shingrix, the only currently approved and recommended herpes zoster vaccine available in the United States
Lawrence Steinman, MD, a professor of neurology and neurological sciences, pediatrics, and genetics at Stanford (Calif.) Medicine, was not involved in the research but said in an interview that the findings “raise the issue of whether not enough individuals with MS are getting Shingrix, and also whether there is a need for rapid intervention with an antiviral, for those individuals who develop shingles.”
Real-world data
For the study, researchers analyzed U.S. administrative claims data from the Optum Research Database between October 2015 and March 2022 to compare shingles infections between adults with MS (and no other immunocompromising conditions) and a random sample of one million people without any immunocompromising conditions. The study excluded anyone who had been vaccinated against herpes zoster or diagnosed with it in the year before October 2015.
Among the 42,185 adults with MS included in the cohort, just over half (53%) were commercially insured, and 47% had Medicare Advantage. Their average age was 53, and 75% were female. Just over half the cohort (55%) had no immunosuppression because of medications while 35% had low immunosuppression from MS therapy and 10% had high immunosuppression from therapy. High suppression meant patients were taking fingolimod, siponimod, ozanimod, ponesimod, cladribine, or a monoclonal antibody except natalizumab. Those with low suppression were taking natalizumab, fumarates, IVIG, glatiramer acetate, interferon beta or a related drug, teriflunomide, azathioprine, methotrexate, or mycophenolate mofetil.
The rate of shingles infections in the MS patient population was 13.8 per 1,000 people per year, compared with 5.6 infections per 1,000 immunocompetent people per year (adjusted incident rate ratio, 1.69; 95% confidenceinterval, 1.58-1.81. When broken down by age, younger adults aged 18-49 with MS were more than three times more likely to develop shingles (incidence rate, 11.6 per 1,000 people per year) than immunocompetent younger adults (IR, 3.5). The gap was narrower for those age 50 and older, where adults with MS had a rate of 15.2 infections per 1,000 people per year versus 8.6 per 1,000 immunocompetent people per year.
Although MS patients with a higher baseline level of immunosuppression from therapy had higher herpes zoster infection rates (18 cases per 1,000 people per year) than those with low immunosuppression (14 cases per 1,000 people per year) or no immunosuppression from medication (13 cases per 1,000 people per year), rates for all three remained higher than for the immunocompetent population.
Herpes and MS: Some questions still unanswered
“We’ve known that herpes zoster is more common in people with MS, and we’ve known that it is seen in people on MS therapies,” Robert Fox, MD, a staff neurologist at the Mellen Center for MS and vice-chair for research at the Neurological Institute at the Cleveland Clinic, said in an interview. “What we haven’t known is just how much more common it is in people with MS than the rest of the adult population and whether it truly is more common in people taking MS therapies than people not taking MS therapies. This study puts real, population-based numbers on the incidence rates.”
Dr. Fox, who was not involved in the research, noted that a limitation of the study was the inability to know the risk of shingles according to specific MS therapies since all the therapies were grouped together.
”So I can’t say to a patient that their particular therapy increases their risk,” Dr. Fox said. “Similarly with the MS therapies listed in the ‘high’ immunosuppression category: We don’t know that each of the therapies listed do in fact increase the rate of herpes zoster. We just know that the group of MS therapies bunched into the ‘high’ category, on the whole, increase the rate of herpes zoster.”
The study does not provide any information about the impact of Shingrix vaccination, he added, since vaccinated individuals were excluded from the analysis.

Ozanimod for relapsing MS shows long-term safety, efficacy with age differences
AURORA, COLO. – , according to research presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.
Research from the phase 3 DAYBREAK trial had already shown the safety of ozanimod, and the Food and Drug Administration approved the drug as an oral disease-modifying therapy for relapsing forms of MS in 2020.
“In the DAYBREAK study, we already have shown that the clinical and radiological disease was quite low in these patients who received the higher dose of ozanimod, and those who switched from the lower dose of the interferon to this active treatment also had decreases in their annualized relapse rate and their MRI lesion counts,” Sarah Morrow, MD, associate professor of neurology at Western University in London, Ontario, told attendees. She presented the data on behalf of senior author Bruce Cree, MD, PhD, professor of neurology and clinical research director at the University of California, San Francisco, Multiple Sclerosis Center, and the other authors. “But what was not known was whether there’s a difference in efficacy based on age, and we know that disease activity can differ based on age in person with relapsing multiple sclerosis.”
Examining efficacy by age
Analysis of data from DAYBREAK and an open-label extension study revealed that respiratory infections were more common in patients younger than 35, and urinary tract infections, dizziness, and treatment-emergent depressive symptoms became were common in patients age 50 and older. “Serious infections did not vary by age, and there were too few serious events to identify any age-related trends by specific TEAE,” the authors reported. During the open-label extension of the study, no new adverse events emerged, “confirming the ozanimod safety profile reported in the parent trials,” SUNBEAM and RADIANCE, the authors reported.
The phase 3 parent trials compared 30 mcg once weekly of intramuscular interferon beta-1a to 0.92 mg of once-daily oral ozanimod and 0.46 mg of once-daily oral ozanimod. In the DAYBREAK open-label extension, 2,256 participants underwent a dose escalation over 1 week until all reached 0.92 mg of ozanimod, where they remained for approximately 5 years of follow-up. The researchers then analyzed TEAEs, serious adverse events, and TEAEs leading to discontinuation in four age categories: 18-25, 26-35, 36-49, and 50 and older.
Respiratory infections occurred more often in those aged 18-25 (10.9%) and 26-35 (6.1%) than in those 36-49 (5.8%) and 50 and older (3.4%). However, UTIs occurred most in those age 50 and older (9.2%), versus occurring in 6.6% of those 36-49, 4.3% of those aged 26-35, and 4.6% of those 18-25.
High cholesterol occurred significantly less often in those 18-25 (1.4%) and 26-35 (2%) than in those 36-49 (5%) and 50 and older (8%), and hypertension showed a similar pattern: 2% in the youngest group, 4.7% in those aged 26-35, 12.8% in those aged 36-49, and 16.7% in those aged 50 and older.
Other TEAEs that occurred more often in older patients included depression/depressive symptoms, dizziness, back pain, joint pain, osteoarthritis, and high gamma-glutamyl transferase (GGT) levels. Overall cardiac and vascular disorders and malignancies were also more common as participants’ age increased.
Bigger concerns?
The increase in malignancy risk by age surprised Shailee Shah, MD, assistant professor of neuroimmunology and neurology at Vanderbilt University Medical Center, Nashville, Tenn., who was not involved in the research. This increase in risk was “not expanded upon much in this abstract or compared to population estimates, as this may ultimately be one of the bigger concerns with long-term use of this drug,” Dr. Shah said.
She further noted that “older patients may be at higher risk of infections and multiple cardiovascular risk factors, and so if patients already have comorbid disease, I may be less inclined to use this agent and likely less so in older individuals.”
Dr. Shah said these drugs are often recommended to individuals in their 20s and 30s at time of diagnosis. “If a patient is given this drug and tolerates it and finds it efficacious, we might continue this indefinitely, so looking at how the risk profile of young patients on this drug changes over time will be important,” Dr. Shah said. “I am also concerned about the malignancy risk and would want this elaborated upon.”
Overall efficacy across age groups
Serious infections occurred at relatively similar rates across all age groups. Incidence of any serious adverse event was 27 per 1,000 people per year in the youngest group compared with 24 events in the 26-35 group, 35 events in the 36-49 group, and 62 events per 1,000 people per year in those 50 and older.
“Patients in the 50 and older age group had a numerically lower adjusted annualized relapse rate and less gadolinium-enhancing lesions and new or enlarging T2 lesions per scan and were generally more likely to be free of gadolinium-enhancing lesions or new or enlarging T2 lesions than the 25 and younger age group,” Dr. Morrow told attendees, “but we feel that that’s more in keeping with the natural history of disease. And, overall, ozanimod, regardless of the age group, showed decreasing disease activity in the inflammatory part of disease, showing with annualized relapse rate, gad-enhancing lesions, and T2 lesions.”
Older participants were substantially more likely to withdraw from the trial because of adverse events. While 8% of the youngest group and 7.6% of participants aged 26-35 withdrew because of adverse events, 24.5% of those aged 36-49 and 18.5% of those aged 50 and older withdrew because of adverse events.
Dr. Shah said it was reassuring that no new safety signals emerged, “but based on this data, you would be concerned that long-term risk of cardiovascular disease may result in more serious adverse events over a longer period of time and will need to be considered as we see people increasingly on this drug.”
The research was funded by Bristol-Myers Squibb. The authors reported a wide range of financial disclosures, including personal fees, research funding, advisory board, and speakers fees, for multiple pharmaceutical companies, including Bristol-Myers Squibb, and five authors are employees and/or shareholders of the company. Dr. Shah has served on advisory boards for Alexion, Genentech, and Horizon.

Multiple changes in NMOSD treatment for nonmedical reasons tied to poorer outcomes
DENVER – , new research shows.
“For the first time, we were able to quantify clinical outcomes associated with treatment transitions in people with NMOSD. Our data highlight that aspects outside of therapeutic efficacy may be remarkably meaningful in the effective suppression of disease advancement,” said senior investigator Darin T. Okuda, MD, professor of neurology and director of the neuroinnovation program at University of Texas Southwestern Medical Center in Dallas.
The findings were presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.
Treatment delayed?
NMOSD, an inflammatory syndrome of the central nervous system, can cause irreversible disability. As treatments have improved over time, transitioning from one medication to newer options has become increasingly common.
To better understand the effects of multiple treatment transitions, the researchers conducted a retrospective analysis of electronic medical records of 164 patients with aquaporin-4 IgG–positive NMOSD. Of these individuals, 89 met the study’s inclusion criteria.
Of the participants, 89% were female, and the median disease duration was 10.1 years. Forty-two patients had switched therapies at least once; 26 switched at least twice; 12 switched at least three times; six switched four times; and three switched therapies five times or more for a total of 174 treatment transitions.
Patients were stratified into two groups – those who transitioned for medical reasons (53.4%), and those who switched because of nonmedical/tolerability reasons (46.6%).
Top reasons for transitioning in the medical category included clinical relapse and/or new MRI activity (29.9%), physician-directed transition (11.5%), and increased physical or clinical disability (4.0%). Leading reasons for nonmedical transitions were side effects (16.7%), adherence/persistence (8.1%), and cost/access (5.75%).
A recurrent event survival analysis showed that, after just one transition for nonmedical or tolerability reasons, outcomes significantly improved, with the risk of hospitalization decreasing 40.3% (P = .005), the risk of relapse decreasing by 53.1% (P = .002), and the risk of advancement on MRI decreasing by 65.9% (P = .005).
Conversely, each additional drug discontinuation in the nonmedical group was associated with worse outcomes. These included a 25.2% increased risk of hospitalization (P = .0003), a 24.4% increase in relapse risk (P = .06), and a 41.9% increased risk of MRI advancement (P = .03).
In terms of transitions for medical reasons, there was a significantly increased risk of MRI advancement with the first switch (32.2%; P = .005). However, no significant increases in risk were associated with each additional transition (P = .33).
The median time spent on the first treatment was 306 days in the transition for medical reasons group and 378 days for the nonmedical/tolerability group.
The median duration of time spent between treatments during the initial transition was just 7 days among those transitioning for medical reasons versus 91 days for nonmedical reasons, with the median duration of additional transitions also substantially longer in the nonmedical reasons group, at 22 and 80 days, respectively.
“The median time spent on a first-line therapy regardless of [whether] that first transition was due to a medical or nonmedical tolerability reason was similar; however, the duration of that initial transition was 13 times longer if the transition had to do with a nonmedical or tolerability reason,” first author Alexander D. Smith, a clinical data specialist at UT Southwestern Medical Center, told conference delegates. “Similarly, each additional transition was almost four times longer if it had to do with a nonmedical or tolerability reason,” he said.
Dr. Okuda noted the longer window between treatment transitions may be a key factor in the different outcomes between the groups. “A central theory involves the increased amount of time between treatments,” he said.
“The reasons for the delay in starting a new treatment may be related to a variety of factors, including laboratory testing required to start a new treatment, third-party administrator coverage, time for the resolution of adverse reactions, and/or personal factors from the individual undergoing treatment, etc.”
Another factor, Mr. Smith said in his talk, is that, “when people are left miserable by a prior treatment exposure, they may simply be hesitant to get on the next therapy.”
The finding that only MRI advancement was associated with transitions for medical reasons suggests that worsening disease activity is not necessarily behind increased transitions, with nonmedical reasons often the cause, and more likely to be associated with the worse outcomes.
With the time between treatments a possible culprit, Dr. Okuda said the clinical implications are that “treatment transitions, regardless of the reason, should occur as quickly as possible to reduce the risk for disease progression associated with NMOSD.”
Mr. Smith echoed the suggestion, adding that “it’s important that even if disease activity is not present, complacency should be avoided.”
“Clinicians and third-party administrators should work to ensure that people with NMOSD have accelerated switches onto their next therapy, even if that disease activity is not present. In a sense, rapid treatment transitions may have equitable benefits to the treatments themselves,” Mr. Smith added.
Important research
Commenting on the study, Shailee Shah, MD, an assistant professor in the Neuroimmunology division at Vanderbilt University Medical Center, in Nashville, Tenn., noted the findings are consistent with generally higher concerns around switching treatments for nonmedical reasons.
“In general, if a high-efficacy medication is started, it appears that patients are less likely to require a transition to a different medication. It is a little harder to predict who may have issues with tolerability or nonmedical reasons to transition medications, and many providers would likely agree that these transitions do raise some concerns about the risk of relapse or hospitalization in the interim,” she said.
Dr. Shah added that in her experience patients who require multiple transitions are either started on lower-efficacy medications at treatment initiation or have highly refractory disease.
The study’s findings underscore that “identifying additional risk factors and underlying reasons for these findings will be imperative in the future,” Dr. Shah said.
The study was supported by Revert Health, a corporation founded by Dr. Okuda. Dr. Okuda reports receiving personal compensation for consulting and advisory services from Alexion, Biogen, Celgene/Bristol Myers Squibb, EMD Serono, Genentech, Genzyme, Janssen Pharmaceuticals, Novartis, Osmotica Pharmaceuticals, RVL Pharmaceuticals, TG Therapeutics, Viela Bio, and research support from Biogen, EMD Serono/Merck, and Novartis.

Racial, ethnic disparities persist in access to MS care
Aurora, Colo. – , according to research on patient-reported health inequities presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.
”Equal access to and quality of care are critical for managing a progressive disease such as multiple sclerosis,” said Chris Hardy, of Publicis Health Media, and her associates. “Despite increased awareness of health outcome disparities in the U.S., certain patients still experience inequities in care.”
The researchers sent emails to members of MyMSTeam, an online support network of more than 197,000 members, to request completion of a 34-question online survey. Questions addressed respondents’ ability to access care, resources in their neighborhood, and their interactions with their health care providers. Questions also addressed the burden of MS on individuals’ quality of life, which was considerable across all demographics. The 1,935 patients with MS who responded were overwhelmingly White, though the demographics varied by question.
A ‘widespread and significant problem’
“This study is important in pointing out the unfortunate, obvious [fact] that lack of access and lack of availability to treatment is still a widespread and significant problem in this country,” commented Mark Gudesblatt, MD, a neurologist at South Shore Neurologic Associates who was not involved in the study. “Improving effective treatment of disease requires a more granular understanding of disease impact on a quantitative, multidimensional, objective patient-centric approach,” he added. “Racial and ethnic barriers to effective treatment cannot be allowed nor tolerated. We need to be more acutely aware that outreach, digital health, and remote assessments are tools that we need to incorporate to improve access and do better.”
The pervasive impact of MS
Overall, 85% of respondents reported that MS made it harder to do everyday chores, and 84% said their MS made it harder to exercise and interfered with their everyday life. Similarly high proportions of respondents reported that their MS causes them a lot of stress (80%), makes them feel anxious or depressed (77%), disrupts their work/employment (75%), and interferes with their social life (75%). In addition, more than half said their diagnosis negatively affects their family (59%) and makes them feel judged (53%).
Deanne Power, RN, MSCN, the lead nurse care partner at Octave Bioscience, who spoke as a representative of the study authors, said it’s critical that clinicians be aware of the health inequities that exist among their patient population.
“Some patients have lower income or language issues where English is not their primary language, and they don’t have access and are even afraid to call doctor or reach out [for help],” Ms. Power said. “If providers aren’t actively aware of these situations and talk to their patients, they can’t just say, ‘Oh, well, I just want you to go fill this prescription,’ when they don’t have money to put food on their table. Providers have got to know their patients as [more than] just an MS patient. This is a human being in front of you, and you better know what their life is like, because it’s impacting their MS.”
Access to care varied by race
Among the 1,906 respondents who answered questions about access to care, 9% were Black, 5% were Hispanic, and the rest were White. In these questions, differences between demographics arose when it came to individuals’ ability to conveniently see an MS specialist and their subsequent use of emergency services. For example, only 64% of Hispanic respondents reported convenient access to a health care provider specializing in MS, compared with 76% of White and 78% of Black respondents.
A significantly higher proportion of Hispanics also reported that they could not take time off from work when they were sick (25%) or to attend a doctor appointment (20%), compared with White (15% and 9%, respectively) and Black (18% and 12%) respondents. Meanwhile, a significantly higher proportion of Hispanics (35%) reported visiting the emergency department in the past year for MS-related issues, compared with White (19%) or Black (25%) respondents.
White respondents consistently had greater convenient access to dental offices, healthy foods, outpatient care, gyms, and parks and trails, compared with Black and Hispanic patients’ access. For example, 85% of White patients had convenient access to dental offices and 72% had access to outpatient care, compared with Black (74% and 65%) and Hispanic (78% and 52%) patients. Two-thirds of Hispanic respondents (67%) reported access to healthy foods and to gyms, parks, or trails, compared with more than three-quarters of both White and Black patients.
Other barriers to MS care
Both racial/ethnic and gender disparities emerged in how patients felt treated by their health care providers. Men were significantly more likely (70%) than women (65%) to say their health care provider listens to and understands them. A statistically significant higher proportion of men (71%) also said their clinician explained their MS test results to them, compared with women (62%), and only 28% of women, versus 37% of men, said their provider developed a long-term plan for them.
Anne Foelsch, the vice president of strategic partnerships at MyHealthTeam, who works with the authors, noted the large discrepancy that was seen particularly for Hispanic patients in terms of how they felt treated by their health care provider.
“Doctors might perceive that the relationship is the same with all of their patients when their patients have a very different perception of what that relationship is and whether they’re not being heard,” Ms. Foelsch said. “It’s important that clinicians take a little bit of time and learn a little bit more about a patient’s perspective and what it’s like when they have a chronic condition like MS and how it impacts their life, looking for those nuances that are different based on your ethnicity.”
Just over half of Hispanic patients (54%) said their provider explained their MS test results, compared with nearly two-thirds of White patients (65%) and 61% of Black patients. Hispanic patients were also less likely (55%) to say they felt their provider listens to and understands them than White (67%) or Black (65%) patients. Two-thirds of White respondents (67%) said their doctor recommended regular check-ups, compared with just over half of Black and Hispanic respondents (55%).
Other statistically significant disparities by race/ethnicity, where a higher proportion of White patients responded affirmatively than Black or Hispanic patients, included feeling treated with respect by their health care provider, feeling their provider is nonjudgmental, and saying their provider spends enough time with them, addresses their MS symptoms, and encourages shared decision-making.
“This study nicely documents and points out that despite our best intentions, we need to do much better as a community to help those with chronic and potentially disabling diseases like MS,” Dr. Gudesblatt said. “The racial, ethnic, and gender disparities only result in greater disability and societal costs by those who can least afford it. All therapies fail due to nonadherence, limited access, lack of insurance coverage, limited insurance coverage, high copays, long waits, cultural biases, and more.”
The researchers acknowledged that their survey respondents may not be representative of all patients with MS because the survey relied on those who chose to respond to the online survey.
The study authors were all employees of Publicis Health Media or MyHealthTeam. Dr. Gudesblatt reported no disclosures.

We need to be more acutely aware that outreach, digital health, and remote assessments are tools that we need to incorporate to improve access and do better.”
The pervasive impact of MS
Overall, 85% of respondents reported that MS made it harder to do everyday chores, and 84% said their MS made it harder to exercise and interfered with their everyday life. Similarly high proportions of respondents reported that their MS causes them a lot of stress (80%), makes them feel anxious or depressed (77%), disrupts their work/employment (75%), and interferes with their social life (75%). In addition, more than half said their diagnosis negatively affects their family (59%) and makes them feel judged (53%).
Deanne Power, RN, MSCN, the lead nurse care partner at Octave Bioscience, who spoke as a representative of the study authors, said it’s critical that clinicians be aware of the health inequities that exist among their patient population.
“Some patients have lower income or language issues where English is not their primary language, and they don’t have access and are even afraid to call doctor or reach out [for help],” Ms. Power said. “If providers aren’t actively aware of these situations and talk to their patients, they can’t just say, ‘Oh, well, I just want you to go fill this prescription,’ when they don’t have money to put food on their table. Providers have got to know their patients as [more than] just an MS patient. This is a human being in front of you, and you better know what their life is like, because it’s impacting their MS.”
Access to care varied by race
Among the 1,906 respondents who answered questions about access to care, 9% were Black, 5% were Hispanic, and the rest were White. In these questions, differences between demographics arose when it came to individuals’ ability to conveniently see an MS specialist and their subsequent use of emergency services. For example, only 64% of Hispanic respondents reported convenient access to a health care provider specializing in MS, compared with 76% of White and 78% of Black respondents.
A significantly higher proportion of Hispanics also reported that they could not take time off from work when they were sick (25%) or to attend a doctor appointment (20%), compared with White (15% and 9%, respectively) and Black (18% and 12%) respondents. Meanwhile, a significantly higher proportion of Hispanics (35%) reported visiting the emergency department in the past year for MS-related issues, compared with White (19%) or Black (25%) respondents.
White respondents consistently had greater convenient access to dental offices, healthy foods, outpatient care, gyms, and parks and trails, compared with Black and Hispanic patients’ access. For example, 85% of White patients had convenient access to dental offices and 72% had access to outpatient care, compared with Black (74% and 65%) and Hispanic (78% and 52%) patients. Two-thirds of Hispanic respondents (67%) reported access to healthy foods and to gyms, parks, or trails, compared with more than three-quarters of both White and Black patients.
Other barriers to MS care
Both racial/ethnic and gender disparities emerged in how patients felt treated by their health care providers. Men were significantly more likely (70%) than women (65%) to say their health care provider listens to and understands them. A statistically significant higher proportion of men (71%) also said their clinician explained their MS test results to them, compared with women (62%), and only 28% of women, versus 37% of men, said their provider developed a long-term plan for them.
Anne Foelsch, the vice president of strategic partnerships at MyHealthTeam, who works with the authors, noted the large discrepancy that was seen particularly for Hispanic patients in terms of how they felt treated by their health care provider.
“Doctors might perceive that the relationship is the same with all of their patients when their patients have a very different perception of what that relationship is and whether they’re not being heard,” Ms. Foelsch said. “It’s important that clinicians take a little bit of time and learn a little bit more about a patient’s perspective and what it’s like when they have a chronic condition like MS and how it impacts their life, looking for those nuances that are different based on your ethnicity.”
Just over half of Hispanic patients (54%) said their provider explained their MS test results, compared with nearly two-thirds of White patients (65%) and 61% of Black patients. Hispanic patients were also less likely (55%) to say they felt their provider listens to and understands them than White (67%) or Black (65%) patients. Two-thirds of White respondents (67%) said their doctor recommended regular check-ups, compared with just over half of Black and Hispanic respondents (55%).
Other statistically significant disparities by race/ethnicity, where a higher proportion of White patients responded affirmatively than Black or Hispanic patients, included feeling treated with respect by their health care provider, feeling their provider is nonjudgmental, and saying their provider spends enough time with them, addresses their MS symptoms, and encourages shared decision-making.
“This study nicely documents and points out that despite our best intentions, we need to do much better as a community to help those with chronic and potentially disabling diseases like MS,” Dr. Gudesblatt said. “The racial, ethnic, and gender disparities only result in greater disability and societal costs by those who can least afford it. All therapies fail due to nonadherence, limited access, lack of insurance coverage, limited insurance coverage, high copays, long waits, cultural biases, and more.”
The researchers acknowledged that their survey respondents may not be representative of all patients with MS because the survey relied on those who chose to respond to the online survey.
The study authors were all employees of Publicis Health Media or MyHealthTeam. Dr. Gudesblatt reported no disclosures.

Long-term freedom from NMOSD relapse with satralizumab
DENVER – , new research shows.
“In long-term observations, we are seeing a nice, sustained suppression of relapses early, as well as late, in treatment,” said study investigator Anthony Traboulsee, MD, University of British Columbia, Vancouver, in presenting the findings at the annual meeting of the Consortium of Multiple Sclerosis Centers.
“It remains very tolerable with no participants discontinuing because of side effects,” he said. “And importantly, [there are] no signs of a delayed risk of infections for both monotherapy and combination therapy.”
Satralizumab, a monoclonal recycling antibody, targets the interleukin (IL)–6 receptor, which is elevated in the serum and cerebrospinal fluid of patients in NMOSD.
The drug was approved by the Food and Drug Administration in 2020 for the treatment of AQP4 antibody–positive NMOSD after favorable results from two key trials: SAkuraSky and SAkuraStar.
The FDA approval marked satralizumab as the third therapy for NMOSD, following eculizumab (Soliris) and inebilizumab (Uplizna).
Satralizumab is administered in subcutaneous injections every 4 weeks after a run-in period of injections at weeks 0, 2, and 4.
Longest trial to date
To evaluate the drug’s long-term efficacy in the treatment of AQP4 IgG–positive NMOSD, patients from the two previous phase 3 trials were entered into the single arm, open-label SAkuraMoon study and continued treatment with the satralizumab 120 mg injections once monthly, with or without immunosuppressive therapy.
The study included 106 patients (mean age 44 years, 89.6% women), all of whom had received one or more doses of satralizumab by the data cutoff of January 2022.
With a median duration of satralizumab exposure of 5 years, the overall adjusted annualized rate of investigator protocol-defined relapse (ARR) was 0.09.
Longitudinal assessment further showed no significant increase in the relapse rate over the course of the study, with an ARR rate of 0.16 at year 1; 0.10 at year 2; 0.05 at year 3; and 0.07 at year 4.
At week 240 (4.6 years), 72% of satralizumab-treated patients were relapse-free, with 91% free from severe relapse.
In addition, 85% of patients had no sustained disability, as measured by Expanded Disability Status Scale (EDSS) worsening, over the study period.
Asked if there are potential subgroups of patients who may be more susceptible to the worsening of disability, Dr. Traboulsee responded “not that we can tell as of yet.”
“I would like to explore this further as this is a relatively new observation, and, as far as I know, this is the longest follow-up for an NMO treatment trial cohort,” he said.
Favorable safety profile
The safety profile was also favorable, consistent with results in the earlier trials. The longer exposure to satralizumab was not associated with a higher risk of severe (grade 3 or higher) laboratory changes versus the double-blind studies. “Rates of adverse events and serious adverse events with overall satralizumab treatment were comparable with the double-blind periods,” said Dr. Traboulsee.
“With satralizumab combined with immunosuppressant therapy, we’re not seeing an increased rate of infections, because it’s not an immune suppressant – it doesn’t suppress lymphocytes or lower immunoglobulin,” he added.
While the use of combination therapy has been an important clinical concern, Dr. Traboulsee noted that “this does not appear to be the case with satralizumab when combined with daily prednisone or daily azathioprine.”
“There is no increased risk of infections, compared with placebo, and it interestingly appears lower than patients on prednisone or azathioprine alone,” he said.
While the median follow-up was 5 years, some in the clinical trial population have been on treatment for up to 7.9 years.
“Based on the current safety and efficacy data, they could stay on this therapy indefinitely, in my opinion,” Dr. Traboulsee said.
In addition to its long-term safety and efficacy, satralizumab “is easy for patients to take and does not require access to an infusion center. It’s easy for physicians to monitor safety, especially since no additional vaccinations or precautions are required beyond what is done in routine care.”
“What I conclude from that clinically is that this is a highly effective and safe therapy by itself or in combination with another agent,” Dr. Traboulsee said.
He noted that the lack of a bump in infections is “really encouraging and very important with a chronic disease that affects elderly patients. So far, so good,” he added.
‘A good first-line therapy’
Commenting on the study, Shailee Shah, MD, an assistant professor in the neuroimmunology division at Vanderbilt University Medical Center, Nashville, Tenn., agreed that the findings bode well for satralizumab’s long-term benefits.
“These are promising results and suggest that satralizumab is very effective in the long term, and even when patients relapse, those relapses are less severe than they would likely be if the patient were off therapy,” she said.
She noted that, while the ability to self-administer injections with satralizumab is convenient, preferences vary.
“This is patient dependent,” Dr. Shah said. “For some patients an injectable medication is ideal but for others an infusion medication [such as eculizumab] is preferred.”
Overall, however, Dr. Shah described satralizumab as “a good first-line therapy for patients with NMOSD in addition to eculizumab/ravulizumab and inebilizumab.”
“It is reasonable to consider this medication in isolation or with concomitant immunosuppressive therapy,” she said.
Dr. Traboulsee’s disclosures include relationships with Novartis, Roche, Sanofi (Genzyme), Ingo Kleiter, Alexion, Almirall, Bayer, Biogen, Celgene, Genentech, Hexal, Horizon, Merck, and Sanofi. Dr. Shah reports that she has served on advisory boards for Horizon, Alexion, and Genentech.

Mindfulness-based stress reduction program benefits MS patients
DENVER – The use of according to research presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.
Two studies assessed the effects of two mindfulness-based stress reduction (MBSR) programs, one primarily in person until the pandemic forced a move to online participation, and the other exclusively online. The in-person course also found, in a subset of the participants, that blood inflammation markers matched the patients’ reported reduction in stress and loneliness.
Putting mindfulness to the test
Previous research has found that life stressors are linked to clinical MS flares, Chris Hemond, MD, an assistant professor of neurology at the University of Massachusetts, Worcester, told attendees. He also noted previous research exploring possible explanations for how MBSR programs might improve clinical symptoms of MS. One hypothesis involves an effect on the “forebrain limbic areas responsible for the neurobiological stress response.” Part of this study therefore involved looking for possible MRI changes before and after the MBSR program to test this hypothesis.
The study involved 23 patients, all women with relapsing remitting MS with an median age of 45, and 57% of whom were taking B cell–depleting agents. The patients’ average Expanded Disability Status Scale score was 2, and none experienced any new clinical or MRI disease activity during a 12-week observation period.
Patients volunteered to participate in the free 8-week MBSR program. Half attended MBSR classes in person while the other half had to attend virtual classes due to the pandemic. The program involved eight weekly 2.5-hour classes with daily homework assignments. The program, developed by Jon Kabat-Zinn at the University of Massachusetts, is intended to be “mental training for nonjudgmental awareness of moment-to-moment experience” that aims to “improve accuracy of perception, acceptance of intractable health-related changes, realistic sense of control, and appreciation of available life experiences,” Dr. Hemond said.
Among the 91% of participants who completed the course, 57% underwent both pre- and postcourse structural MRI scans, and 83% completed both the pre- and postcourse questionnaires. A subset of patients (53%) also provided blood samples for analysis of inflammatory gene expression markers.
“The conserved transcriptional response to adversity (CTRA) score was determined using well-established methods from 53 prespecified blood gene expression markers representing a composite of inflammation, interferon response, and immunoglobulin expression,” Dr. Hemond explained.
Participants’ average scores both pre- and post questionnaires revealed statistically significant improvements in stress, anxiety, depression, fatigue, loneliness, well-being, and interoceptive awareness (P < .01 for all).
Although precise values were not provided in the presentation, patients’ scores significantly decreased on the Brief Inventory of Perceived Stress (BIPS) for “lack of control,” “pushed,” and “conflict” (P < .03). Average scores also improved (decreased) on the Modified Fatigue Inventory Scale, the UCLA Loneliness Scale, and all three subscales of the Depression Anxiety Stress Scales assessment (P <.01). Participants’ scores increased on the Mental Health Continuum “hedonic” and “eudaimonic well-being” scales (P < .05).
Improvements on the Multidimensional Assessment of Interoceptive Awareness included self-regulation, attention regulation, “noticing” (P = .02), “not worrying” (P < .01), “emotional awareness” (P < .01), “body listening” (P < .01), and “trusting” (P < .01).
After adjustment for age, race, body mass index, medical therapy and time, the researchers found changes in inflammatory gene expression in the 12 participants who provided blood samples, and these changes correlated inversely with changes in their reported loneliness (P =.002), pain (P <.001), several interoception aspects (P < .01), and stress (P < .0001), particularly regarding feeling a lack of control.
Although no structural MRI changes were observed in the amygdala or prefrontal cortex, the researchers did see a 1% volume increase on the right-side hippocampus. Though the increase was significant (P < .01) and right hippocampal enlargement has been linked with MBSR in past studies, Dr. Hemond acknowledged the study’s small sample size and urged caution in interpreting that finding.
Dr. Hemond also reported that interaction between higher CTRA and the MSBR training attenuated the right hippocampal volume increase that was seen with MBSR, a finding which raises more questions than it answers.
The primary finding, however, was that “mindfulness-based stress reduction was associated with substantial improvement in multiple patient-reported outcomes of the debilitating ‘silent symptoms’ of MS,” Dr. Hemond told attendees. Though the study is limited by its small sample size, observational biases, and missing data, the findings suggest the possibility that MBSR is also associated with structural limbic brain changes, especially in the right hippocampus.
Another tool for managing MS
Ellen Mowry, MD, MCR, a professor of neurology and epidemiology at Johns Hopkins University, Baltimore, who attended the presentation, said she was very enthusiastic about this research.
“People with MS often are seeking ways that they can have self-efficacy and managing the symptoms of their disease, and we know that the disease-modifying therapies make a big difference, but we need additional therapies that can help people feel better and live better with MS,” Dr. Mowry commented.
She also acknowledged the challenges, however, in developing a mindfulness program that is accessible by a broad range of MS patients. This particular program involved several hours of work per day.
“People with MS often are either on the younger side, and they’re working and raising their family and doing all the same stuff that everybody else is doing, or they might be quite disabled and have more fatigue and other things that might make it really challenging to persist through that long of an intervention,” Dr. Mowry said.
The ideal program would be one that’s financially accessible, either through insurance, society more broadly, or another source, and which is logistically feasible for a wide range of patients. Finding a “sweet spot” with a program that doesn’t “require such a lengthy amount of time in order to see a success would be really great,” Dr. Mowry said. “You have to start somewhere, though, and you have to start with a program that’s already been tried and true and work from there.”
An online-only mindfulness program
One possible way to find that sweet spot is through an all-online program that patients access from home, similar to the 8-week MBSR program offered by Concord (N.H.) Hospital featured in the second study. The program was conducted via Zoom during once weekly synchronous meetings throughout 2021 and 2022 for eight cohorts of 5-15 participants each. The time of day the program was offered alternated between evening and daytime courses each quarter and was free for patients because of a hospital grant, according to Nicole Delcourt, BSN, RN, MSCN, of Concord Hospital Neurology, who facilitated patient sign-ups for the program.
Before and after each 8-week course, participants completed the PHQ-9, the PROMIS Cognitive Function, the PROMIS Fatigue–MS, and the Wasson Health Confidence assessments. Among the total 77 participating adults with MS, the completion rate was 81%, with 73% completing the preprogram assessments and 53% completed the postprogram assessments.
The assessments revealed a statistically significant increase in cognitive function and health confidence and decrease in depressive symptoms and fatigue following the program. Participants’ average PROMIS Cognitive Function scores increased from 16.7 before the program to 22.4 after, and their average Wasson Health Confidence score increased from 13.6 to 15.3 (P < .01 for both). Meanwhile, improvement in depressive symptoms was seen in participants’ decrease in Patient Health Questionnaire–9 scores from an average 6.9 to 4.6 (P = .01), and their average PROMIS Fatigue scores fell slightly but significantly from 59.3 to 55.3 (P < .05).
The participants “really felt like they were more in touch with their own feelings and emotions, and it helped them self-regulate,” Ms. Delcourt sad, “so it was really exciting.”
Patients also expressed satisfaction more subjectively in their feedback surveys. “I feel more aware of my body’s reactions to food and movement, and things that make me feel better physically,” one participant said. Another said that the class’s “lasting value ... will be to remember my own needs and how to become one with them.” Another participant praised the relevance of the printed and course materials, the speed of feedback on homework, and the quality of the video conference.

The in-person program study was funded by CMSC. Funding information for the Concord online program was unavailable.

Among the 91% of participants who completed the course, 57% underwent both pre- and postcourse structural MRI scans, and 83% completed both the pre- and postcourse questionnaires. A subset of patients (53%) also provided blood samples for analysis of inflammatory gene expression markers.
“The conserved transcriptional response to adversity (CTRA) score was determined using well-established methods from 53 prespecified blood gene expression markers representing a composite of inflammation, interferon response, and immunoglobulin expression,” Dr. Hemond explained.
Participants’ average scores both pre- and post questionnaires revealed statistically significant improvements in stress, anxiety, depression, fatigue, loneliness, well-being, and interoceptive awareness (P < .01 for all).
Although precise values were not provided in the presentation, patients’ scores significantly decreased on the Brief Inventory of Perceived Stress (BIPS) for “lack of control,” “pushed,” and “conflict” (P < .03). Average scores also improved (decreased) on the Modified Fatigue Inventory Scale, the UCLA Loneliness Scale, and all three subscales of the Depression Anxiety Stress Scales assessment (P <.01). Participants’ scores increased on the Mental Health Continuum “hedonic” and “eudaimonic well-being” scales (P < .05).
Improvements on the Multidimensional Assessment of Interoceptive Awareness included self-regulation, attention regulation, “noticing” (P = .02), “not worrying” (P < .01), “emotional awareness” (P < .01), “body listening” (P < .01), and “trusting” (P < .01).
After adjustment for age, race, body mass index, medical therapy and time, the researchers found changes in inflammatory gene expression in the 12 participants who provided blood samples, and these changes correlated inversely with changes in their reported loneliness (P =.002), pain (P <.001), several interoception aspects (P < .01), and stress (P < .0001), particularly regarding feeling a lack of control.
Although no structural MRI changes were observed in the amygdala or prefrontal cortex, the researchers did see a 1% volume increase on the right-side hippocampus. Though the increase was significant (P < .01) and right hippocampal enlargement has been linked with MBSR in past studies, Dr. Hemond acknowledged the study’s small sample size and urged caution in interpreting that finding.
Dr. Hemond also reported that interaction between higher CTRA and the MSBR training attenuated the right hippocampal volume increase that was seen with MBSR, a finding which raises more questions than it answers.
The primary finding, however, was that “mindfulness-based stress reduction was associated with substantial improvement in multiple patient-reported outcomes of the debilitating ‘silent symptoms’ of MS,” Dr. Hemond told attendees. Though the study is limited by its small sample size, observational biases, and missing data, the findings suggest the possibility that MBSR is also associated with structural limbic brain changes, especially in the right hippocampus.
Another tool for managing MS
Ellen Mowry, MD, MCR, a professor of neurology and epidemiology at Johns Hopkins University, Baltimore, who attended the presentation, said she was very enthusiastic about this research.
“People with MS often are seeking ways that they can have self-efficacy and managing the symptoms of their disease, and we know that the disease-modifying therapies make a big difference, but we need additional therapies that can help people feel better and live better with MS,” Dr. Mowry commented.
She also acknowledged the challenges, however, in developing a mindfulness program that is accessible by a broad range of MS patients. This particular program involved several hours of work per day.
“People with MS often are either on the younger side, and they’re working and raising their family and doing all the same stuff that everybody else is doing, or they might be quite disabled and have more fatigue and other things that might make it really challenging to persist through that long of an intervention,” Dr. Mowry said.
The ideal program would be one that’s financially accessible, either through insurance, society more broadly, or another source, and which is logistically feasible for a wide range of patients. Finding a “sweet spot” with a program that doesn’t “require such a lengthy amount of time in order to see a success would be really great,” Dr. Mowry said. “You have to start somewhere, though, and you have to start with a program that’s already been tried and true and work from there.”
An online-only mindfulness program
One possible way to find that sweet spot is through an all-online program that patients access from home, similar to the 8-week MBSR program offered by Concord (N.H.) Hospital featured in the second study. The program was conducted via Zoom during once weekly synchronous meetings throughout 2021 and 2022 for eight cohorts of 5-15 participants each. The time of day the program was offered alternated between evening and daytime courses each quarter and was free for patients because of a hospital grant, according to Nicole Delcourt, BSN, RN, MSCN, of Concord Hospital Neurology, who facilitated patient sign-ups for the program.
Before and after each 8-week course, participants completed the PHQ-9, the PROMIS Cognitive Function, the PROMIS Fatigue–MS, and the Wasson Health Confidence assessments. Among the total 77 participating adults with MS, the completion rate was 81%, with 73% completing the preprogram assessments and 53% completed the postprogram assessments.
The assessments revealed a statistically significant increase in cognitive function and health confidence and decrease in depressive symptoms and fatigue following the program. Participants’ average PROMIS Cognitive Function scores increased from 16.7 before the program to 22.4 after, and their average Wasson Health Confidence score increased from 13.6 to 15.3 (P < .01 for both). Meanwhile, improvement in depressive symptoms was seen in participants’ decrease in Patient Health Questionnaire–9 scores from an average 6.9 to 4.6 (P = .01), and their average PROMIS Fatigue scores fell slightly but significantly from 59.3 to 55.3 (P < .05).
The participants “really felt like they were more in touch with their own feelings and emotions, and it helped them self-regulate,” Ms. Delcourt sad, “so it was really exciting.”
Patients also expressed satisfaction more subjectively in their feedback surveys. “I feel more aware of my body’s reactions to food and movement, and things that make me feel better physically,” one participant said. Another said that the class’s “lasting value ... will be to remember my own needs and how to become one with them.” Another participant praised the relevance of the printed and course materials, the speed of feedback on homework, and the quality of the video conference.

DENVER – The use of according to research presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.
Two studies assessed the effects of two mindfulness-based stress reduction (MBSR) programs, one primarily in person until the pandemic forced a move to online participation, and the other exclusively online. The in-person course also found, in a subset of the participants, that blood inflammation markers matched the patients’ reported reduction in stress and loneliness.
Putting mindfulness to the test
Previous research has found that life stressors are linked to clinical MS flares, Chris Hemond, MD, an assistant professor of neurology at the University of Massachusetts, Worcester, told attendees. He also noted previous research exploring possible explanations for how MBSR programs might improve clinical symptoms of MS. One hypothesis involves an effect on the “forebrain limbic areas responsible for the neurobiological stress response.” Part of this study therefore involved looking for possible MRI changes before and after the MBSR program to test this hypothesis.
The study involved 23 patients, all women with relapsing remitting MS with an median age of 45, and 57% of whom were taking B cell–depleting agents. The patients’ average Expanded Disability Status Scale score was 2, and none experienced any new clinical or MRI disease activity during a 12-week observation period.
Patients volunteered to participate in the free 8-week MBSR program. Half attended MBSR classes in person while the other half had to attend virtual classes due to the pandemic. The program involved eight weekly 2.5-hour classes with daily homework assignments. The program, developed by Jon Kabat-Zinn at the University of Massachusetts, is intended to be “mental training for nonjudgmental awareness of moment-to-moment experience” that aims to “improve accuracy of perception, acceptance of intractable health-related changes, realistic sense of control, and appreciation of available life experiences,” Dr. Hemond said.

Stem cell transplants are more effective than some MS therapies
, data indicate.
In a multicenter study that emulated pairwise trials, AHSCT was associated with a higher likelihood of disability improvement, compared with fingolimod (hazard ratio, 2.70).
Once the immune system is reconstituted, it can contribute to the healing process. AHSCT thus provides the possibility of improvement in MS. Disease-modifying therapies that require continued use, however, could inhibit that process.
“If you can stop the inflammation that’s driving this disease fairly early on, [patients] do have the capacity to repair,” said study author Mark Freedman, MD, a professor of neurology at the University of Ottawa. “And we start to see that especially in a treatment [like AHSCT] where you don’t maintain the hit on the immune system.”
The study was published online in JAMA Neurology.
Pairwise analyses
Single-arm studies and an open-label, randomized trial have suggested that AHSCT has efficacy. The regimen is associated with a 0.3%-2.0% risk for mortality, but this risk has declined with better patient selection and clinical experience, according to the researchers. Comparative studies of AHSCT and DMTs are needed, but they are difficult to carry out, which is why the current team chose a propensity-score matched case–control design, according to lead author Tomas Kalincik, MD, PhD, head of the University of Melbourne’s Clinical Outcomes Research Unit.
The researchers examined data from 4,915 patients with relapsing-remitting MS. Of this population, 3.4% received AHSCT, 52.0% received fingolimod, 30.3% received natalizumab, and 14.2% received ocrelizumab. The proportion of women in the treatment groups ranged from 65% to 70%.
The researchers used pairwise matching to simulate the randomized, controlled trials comparing AHSCT with fingolimod, natalizumab, and ocrelizumab. Patients were matched on the basis of sex, age, disability, relapse events at 12 and 24 months before baseline, time from first symptoms to baseline, the most effective previous DMT, and geographical region.
Compared with fingolimod, AHSCT was associated with fewer relapses (annualized relapse rate, 0.09 vs. 0.20; P < .001). This finding was confirmed by a reduced cumulative hazard of relapse (HR, 0.26).
Compared with natalizumab, AHSCT had only a modestly greater effect on annualized relapse rates (ARR, 0.08 vs. 0.10; P = .03), with a cumulative HR for relapses of 0.51.
There was no significant difference in the risk for relapse between treatment with AHSCT and with ocrelizumab (ARR, 0.09 vs. 0.06; P = .86), nor was the risk of cumulative relapses significantly different between these treatments.
Among patients included in the pairwise analyses who received AHSCT, 23.3% developed febrile neutropenia during mobilization, 11.3% developed serum sickness, and 8.8% were admitted to an intensive care unit. There were 82 serious adverse events among 58 patients after they were discharged post AHSCT treatment, including infections (59.8% of adverse events) that were primarily due to viral sources (41.5% of adverse events). There was one death (0.6%) due to veno-occlusive disease of the liver following busulfan exposure.
Some AHSCT protocols are stronger than others, and milder immune ablative measures are less likely to produce lasting effects. “We completely remove the old immune system and put in a brand new one,” said Dr. Freedman, referring to the practice at his center. “That’s a fairly horrendous procedure, and, not surprisingly, we’ve had a slight increase in the types of side effects, compared with other groups who don’t use that heavy-duty conditioning regimen, but we’ve had absolutely zero return of inflammatory events over 23 years that we’ve been doing this. Nobody’s had another attack, no one has even developed a single new MRI lesion.”
The so-called medium and light conditioning regimens are associated with a return of disease activity in about 25% of patients within 3 years, Dr. Freedman added. “You start to see new MRI lesions form and relapses occurring. It’s still better than any of the higher efficacy therapies, but it’s not stopped the disease.”
A key limitation of the study is that its efficacy analysis did not distinguish between different intensities of AHSCT regimens, according to the authors.
Encouraging results
AHSCT is highly effective at temporarily eliminating inflammation in the central nervous system, according to Jeffrey Cohen, MD, director of the Cleveland Clinic’s Mellen Center for MS Treatment and Research, and Anne Cross, MD, professor of neurology at Washington University, St. Louis, who wrote an editorial that accompanied the study. As many as 35% of patients require DMTs at some point after AHSCT.
The results of the new study are encouraging, but plenty of unanswered questions remain, Dr. Cohen said. “Many studies demonstrate AHSCT to have potent durable efficacy that appears to be greater than that of the available DMTs, but some studies – for example, this one – suggest that AHSCT may be superior to some but not all DMTs. Therefore, where to place AHSCT in the overall treatment sequence remains uncertain.” Randomized, controlled trials that are now in process “hopefully will clarify,” he added.

Teriflunomide delays MS symptoms in radiologically isolated syndrome
BOSTON – , according to a double-blind, phase 3 trial presented in the Emerging Science session of the 2023 annual meeting of the American Academy of Neurology.
“These data add to the evidence that early immunomodulation offers clinical benefit even in the presymptomatic phase of MS,” reported Christine Lebrun-Frenay, MD, PhD, head of inflammatory neurological disorders research unit, University of Nice, France. This is the second study to show a benefit from a disease-modifying therapy in asymptomatic RIS patients. The ARISE study, which was presented at the 2022 European Committee for Treatment and Research in MS and has now been published, compared 240 mg of twice-daily dimethyl fumarate with placebo. Dimethyl fumarate was associated with an 82% (hazard ratio, 0.18; P = .007) reduction in the risk of a first demyelinating event after 96 weeks of follow-up.
TERIS trial data
In the new study, called TERIS, the design and outcomes were similar to the ARISE study. Eighty-nine patients meeting standard criteria for RIS were randomized to 14 mg of once-daily teriflunomide or placebo. The majority (71%) were female, and the mean age was 39.8 years. At the time of RIS diagnosis, the mean age was 38 years. At study entry, standardized MRI studies were performed of the brain and spinal cord.
During 2 years of follow-up, 8 of 28 demyelinating events were observed in the active treatment group. The remaining 20 occurred in the placebo group. This translated to a 63% reduction (HR, 0.37; P = .018) in favor of teriflunomide. When graphed, the curves separated at about 6 months and then widened progressively over time.
Distinct from clinically isolated syndrome (CIS), which describes individuals who have a symptomatic episode consistent with a demyelinating event, RIS is based primarily on an MRI that shows lesions highly suggestive of MS. Neither confirms the MS diagnosis, but both are associated with a high likelihood of eventually meeting MS diagnostic criteria. The ARISE and TERIS studies now support therapy to delay demyelinating events.
“With more and more people having brain scans for various reasons, such as headache or head trauma, more of these cases are being discovered,” Dr. Lebrun-Frenay said.
Caution warranted when interpreting the findings
The data support the theory that treatment should begin early in patients with a high likelihood of developing symptomatic MS on the basis of brain lesions. It is logical to assume that preventing damage to the myelin will reduce or delay permanent symptoms and permanent neurologic impairment, but Dr. Lebrun-Frenay suggested that the available data from ARISE and TERIS are not practice changing even though both were multicenter double-blind trials.
“More data from larger groups of patients are needed to confirm the findings,” she said. She expressed concern about not adhering to strict criteria to diagnosis RIS.
“It is important that medical professionals are cautious,” she said, citing the risk of misdiagnosis of pathology of MRI that leads to treatment of patients with a low risk of developing symptomatic MS.
Teriflunomide and dimethyl fumarate, which have long been available as first-line therapies in relapsing-remitting MS, are generally well tolerated. In the TERIS and ARISE studies, mild or moderate events occurred more commonly in the active treatment than the placebo arms, but there were no serious adverse events. However, both can produce more serious adverse events, which, in the case of teriflunomide, include liver toxicity leading to injury and liver failure.
Challenging the traditional definition of MS
The author of the ARISE study, Darin T. Okuda, MD, a professor of neurology at the UT Southwestern Medical Center, Dallas, indicated that his study, now reinforced by the TERIS study, challenges the definition of MS.
“Both ARISE and TERIS demonstrated a significant reduction in seminal clinical event rates related to inflammatory demyelination,” Dr. Okuda said in an interview. They provide evidence that patients are at high risk of the demyelinating events that characterize MS. Given the potential difficulty for accessing therapies of benefit, “how we define multiple sclerosis is highly important.”
“Individuals of younger age with abnormal spinal cord MRI studies along with other paraclinical features related to risk for a first event may be the most ideal group to treat,” he said. However, he agreed with Dr. Lebrun-Frenay that it is not yet clear which RIS patients are the most appropriate candidates.
“Gaining a more refined sense of who we should treat will require more work,” he said.
These data are likely to change the orientation toward RIS, according to Melina Hosseiny, MD, department of radiology, University of California, Los Angeles, Medical Center. She noted that the relationship between RIS and increased risk of MS has long been recognized, and the risk increases with specific features on imaging.
“Studies have shown that spinal cord lesions are associated with a greater than 50% chance of converting to MS,” said Dr. Hosseiny, who was the lead author of a review article on RIS. “Identifying such imaging findings can help identify patients who may benefit from disease-modifying medications.”
Dr. Lebrun-Frenay reports no potential conflicts of interest. Dr. Okuda has financial relationships with Alexion, Biogen, Celgene, EMD Serono, Genzyme, TG Therapeutics, and VielaBio. Dr. Hosseiny reports no potential conflicts of interest.
