Multiple Sclerosis

Dr Mitzi Joi Williams, medical director of the Joi Life Wellness Group in Atlanta, Georgia, shares updates from the 2021 CMSC Annual Meeting on the use of disease-modifying therapies (DMTs) in progressive multiple sclerosis (MS).  

Dr Williams begins with a review of findings from ACAPELLA, a prospective real-world study of ocrelizumab-associated adverse events. The various subanalyses found no higher rates of adverse events on the basis of age or EDSS scores, no downward trend in IgG levels, and mild B-cell repletion that had no significant correlation between disease activity or adverse events. 

Next, she turns to several subanalyses from the EXPAND trial that looked at efficacy and safety of siponimod in patients with secondary progressive MS. Siponimod provided similar clinical benefits in all age groups and was well-tolerated at 3 and 6 months. Several MRI measures were found to be prognostic of disease worsening or improvement. 

Dr Williams concludes with a first look at a new agent, ATA188, which is being studied in adults with progressive forms of MS. This phase 1/2 double-blind, placebo-controlled, dose-expansion trial aims to evaluate the effect of ATA188 on clinical disability, characterize the agent's safety and tolerability, and evaluate the impact of treatment on biological markers in progressive MS.

Dr Mitzi Joi Williams, medical director of Joi Life Wellness Group in Atlanta, Georgia, reviews updates from the 2021 CMSC Annual Meeting focusing on important considerations for patients with multiple sclerosis (MS) who have comorbid physical and mental health conditions.  

She begins with a longitudinal mediation analysis that assessed how differences in socioeconomic status, lifestyle, and comorbidities may affect Black vs White patients with MS. Overall, Black patients had longer timed 25-foot walks than White patients, and it was concluded that elevated BMIs, higher rates of hypertension, and living in lower income neighborhoods all played partial roles in this disparity.  

Dr Williams next discusses a study that examined the prevalence of depression and anxiety in patients with primary-progressive MS (PPMS), secondary-progressive MS (SPMS), and relapsing-remitting MS (RRMS). Rates of both conditions were lower in patients with PPMS than in those with SPMS and RRMS, but overall they were higher in patients with MS compared with the general population.  

The final study she reports on looked at the relationships between cognitive, emotional, and physical factors and weekly engagement in physical activity among patients with MS. Unsurprisingly, meeting weekly physical exercise recommendations was associated with improvement in leg functioning, whereas decreased exercise was associated with increased symptoms of depression and with underweight and obese BMIs.

Up to one-third of patients with multiple sclerosis (MS) treated with the B-cell depleting monoclonal antibody ocrelizumab (Ocrevus) show some degree of repletion of B-cells toward the end of the 6-month infusion cycle. However, there are no corresponding worsening of symptoms or signs of a “wearing off” effect, new research shows.

“Most people expect that since this is a B-cell depleting drug, that if you are not depleting B cells, then that should be reflected clinically and there should be some breakthrough activity,” said study investigator Joshua D. Katz, MD, codirector of the Elliot Lewis Center for Multiple Sclerosis Care in Wellesley, Massachusetts.

Real-world study

Preapproval clinical trials of ocrelizumab suggest about 5% of patients experience a repletion of B cells. However, the timing and association with breakthrough symptoms were unclear.

To investigate, Dr. Katz and colleagues conducted two studies. The first is a substudy of the prospective ACAPELLA trial to assess ocrelizumab-associated adverse events in a real-world population. The study included 294 patients with relapsing and progressive forms of MS treated with at least two cycles of ocrelizumab, given as infusion once every 6 months.

The results showed that overall, 91 (31%) of the 294 patients had some degree of repletion at one or more timepoints.

In categorizing patients according to their highest CD19 measure after two cycles, 108 patients (64.7%) had no significant repletion of B-cells after infusion, defined as an increase of less than 10 cells/μL, while 45 (26.9%) were considered mild repleters, defined as having increases of 10-49 cells/μL.

Seven patients (4.2%) were moderate repleters, with an increase of 50-79 cells/μL, and 7 (4.2%) were categorized as marked repleters, with increases of 80 or more cells/μL.

Eight patients in the study fully repleted, with values from 114-319 cells/μL, occurring between 23 and 34 weeks of the last infusion.

However, there was no relationship between repletion of the B-cells and clinical or MRI evidence of relapse.

Of note, the proportion of patients who did not have B-cell repletion increased with greater numbers of infusions. Whereas 64.7% were non-repleters at cycle 2, that number increased to 88.8% by cycle 6, with a slight drop to 85.6% being non-repleters by cycle 7 (36 months).

“Mild B-cell repletion was fairly common after two cycles of ocrelizumab, but with repeated dosing, a greater proportion of patients were non-repleters, suggesting that cumulative exposure to ocrelizumab results in greater depletion,” the researchers noted.

However, “while the number of moderate or marked repleters in our study was small, they had a tendency to remain repleters over time with subsequent infusions,” they added.

In looking at patient characteristics, moderate and marketed repleters had higher mean BMI (34.1 and 32.6, respectively) compared with the non- and mild repleters (27.0 and 29.4, respectively; P < .0001).

Dr. Katz noted that the increased risk of B-cell repletion with higher BMI was not a surprise. This association, he said, “makes sense” because patients’ relative exposure to ocrelizumab decreases with higher BMI. Similar patterns with BMI were observed in the clinical trial for ocrelizumab approval, in which patients with lower BMI tended to have greater improvement.
 

No symptom worsening

In the second study, the investigators further examined changes in symptom burden related to the amount of time from ocrelizumab infusion. They evaluated 110 patients, aged 18-80 (mean age 44.8) who had Expanded Disability Status Scale (EDSS) scores between 0-7. Study participants were either initiating ocrelizumab or had been on the drug for at least 1 year.

Symptom burden was evaluated with the Neurological Disorders (Neuro-Qol) questionnaire and SymptoMScreen patient-reported outcomes at the beginning of the study at week 4, and near the end of the ocrelizumab infusion cycle, at week 22.

The researchers found that among 69 participants who completed the questionnaires, there were no significant differences at week 22 versus week 4 across a wide range of symptoms, including walking, spasticity, pain, fatigue, cognitive function, dizziness, and depression between the two timepoints.

The only change on the Neuro-QoL score was in the sleep disturbance domain, which improved marginally at the end of the cycle (P = .052). This study did not evaluate changes in B-cells.

Dr. Katz noted that the inclusion of patients over age of 55 in the study offered important insights.

“Our hypothesis was that we were going to start seeing a higher rate of complications, especially infections, in people who are older and may be at a higher risk of infection and disability,” Dr. Katz noted. “But so far, we haven’t seen any higher risk in older patients or those with more disability than anyone else, which is good news.”
 

Amplification of baseline symptoms not uncommon

Commenting on the research, Scott D. Newsome, DO, current president of the CMSC, noted that although no association was observed between the B-cell repletion and symptoms, amplification of flare-up symptoms that are linked to B-cell depleting therapy infusion timing are not uncommon.

“The ‘wearing-off’ phenomenon is not unique to the B-cell therapies,” said Dr. Newsome, who is also director of Johns Hopkins University’s Neurosciences Consultation and Infusion Center and an associate professor of neurology at the JHU med school. “With natalizumab (Tysabri), patients can have an amplification of baseline symptoms as they come closer to their next infusion, and it has been speculated that maybe it was something biologically happening, such as inflammatory cytokines ramping back up or some other mechanisms.”

“Now that we have the B-cell depleting therapies, we tend see the same kind of pattern, where a few weeks leading up to the next infusion, people will develop these amplified symptoms,” he said.

The possibility of a cumulative effect, appearing to address the B-cell repletion associated with early infusions, could have implications over time, Dr. Newsome noted.

“This is important because if people are going on these therapies long-term, the question we may need to ask is whether they actually need to continue to get an infusion every 6 months,” he said.

As these questions around the safety of long-term immunosuppressant drug use continue, different dosing regimens may need to be considered in order to mitigate potential infection risk, he added.

The National Institutes of Health Toolbox Cognitive Battery (NIHTB-CB), a 30-minute, automated, iPad-based battery of psychological tests, offers some key advantages over gold standard cognitive assessments in patients with relapsing-remitting multiple sclerosis (RRMS), new research shows.

An indicator of disease activity?

Cognitive deficits affecting a range of functions – including memory, attention and communication – are common in MS and affect 34% to 65% of patients with the disease, and the ability to detect and monitor such deficits has important implications.

Cognitive changes can provide a unique opportunity to identify acute disease activity in patients with MS that might be already occurring before physical manifestations become apparent, said Ms. Manglani. “If we can detect subtle changes in cognition that might foreshadow other symptoms of disease worsening, we can then allocate interventions that might stave off cognitive decline,” she explained.

While there is an array of well-established neuropsychological tests for the assessment of cognitive deficits, each has limitations, so a shorter, computerized, convenient, and reliable test could prove beneficial.

The NIHTB-CB has been validated in a large, nationally representative sample of individuals aged 8 to 85 and represents a potentially attractive option, yielding composite measures and scores corrected for age, gender, education, race, and ethnicity.
 

Comparative testing

To compare the test with other leading cognition tools used in MS, the investigators recruited 87 patients with RRMS (79% female, mean age 47.3 years). Participants were recruited to perform the full NIHTB-CB (about 30 minutes) and the full Minimal Assessment of Cognitive Function in Multiple Sclerosis (MACFIMS), which takes about 90 minutes, as well as some subsets from the Wechsler Adult Intelligence Scale-IV (WAIS-IV) covering processing speed and working memory. All patients had an EDSS of 5.0 or below and, on average, had been living with MS for about a decade.

The results showed the normative scores for NIHTB-CB had significant concordance with the other measures in terms of processing speed (concordance correlation coefficient [CCC] range = 0.28-0.48), working memory (CCC range = 0.27-0.37), and episodic memory (CCC range = 0.21-0.32). However, agreement was not shown for executive function (CCC range = 0.096-0.11).

Ms. Manglani noted executive function included various submeasures such as planning and inhibitory control. “Perhaps our gold standard measures tapped into a different facet of executive function than measured by the NIHTB,” she said.

The investigators found the proportion of participants classified as cognitively impaired was similar between the MACFIMS and the NIHTB tests.

Further assessment of fluid cognition on the NIHTB-CB – a composite of processing speed, working memory, episodic memory, and executive function that is automatically generated by the toolbox – showed the measure was negatively associated with disease severity, as measured by the EDSS (P = .006). However, the measure was not associated with a difference in depression (P = .39) or fatigue (P = .69).

Of note, a similar association with lower disease severity on the EDSS was not observed with MACFIMS.

“Interestingly, we found that only the NIHTB-CB fluid cognition was associated with disease severity, such that it was associated with nearly 11% of the variance in EDSS scores, and we were surprised that we didn’t see this with MACFIMS,” Ms. Manglani said.
 

Key advantages

The NIHTB-CB was developed as part of the NIH Blueprint for Neuroscience Research initiative and commissioned by 16 NIH Institutes to provide brief, efficient assessment measures of cognitive function.

The battery has been validated in healthy individuals and tested in other populations with neurologic disorders, including patients who have suffered stroke and traumatic brain injury.

Ms. Manglani noted that the NIHTB-CB had key advantages over other tests. “First, it is a 30-minute iPad-based battery, which is shorter than most cognitive batteries available, and one of the few that is completely computerized. In addition, it automatically scores performance and yields a report with both composite scores and scores for each subtest,” she said.

In addition, said Ms. Manglani, “the NIH toolbox has a large validation sample of individuals between 8-85 years of age and provides normative scores that account for age, gender, education, and race/ethnicity, which allows individuals’ performances to be compared with their peers.”

The findings underscore that with further validation, the battery could have an important role in MS, she added.

“The NIH Toolbox needs to be tested in all subtypes of MS, with a full range of disease severity, and in MS clinics to gauge the clinical feasibility. Larger samples and repeated assessments are also needed to assess the test-retest reliability,” she said.

The study had no specific funding. The authors have disclosed no relevant financial relationships.

The National Institutes of Health Toolbox Cognitive Battery (NIHTB-CB), a 30-minute, automated, iPad-based battery of psychological tests, offers some key advantages over gold standard cognitive assessments in patients with relapsing-remitting multiple sclerosis (RRMS), new research shows.

An indicator of disease activity?

Cognitive deficits affecting a range of functions – including memory, attention and communication – are common in MS and affect 34% to 65% of patients with the disease, and the ability to detect and monitor such deficits has important implications.

Cognitive changes can provide a unique opportunity to identify acute disease activity in patients with MS that might be already occurring before physical manifestations become apparent, said Ms. Manglani. “If we can detect subtle changes in cognition that might foreshadow other symptoms of disease worsening, we can then allocate interventions that might stave off cognitive decline,” she explained.

Specialty pharmacists play a key and growing role in navigating the complexities of initiating disease-modifying therapies (DMTs) for multiple sclerosis (MS), resulting in earlier treatment, new data suggest.

Aids early intervention

A report on the Kaiser Permanente Washington (KPWA) MS Pharmacy Program detailed significant reductions in the time to address patients’ needs through the use of specialty pharmacists. In an assessment of 391 referrals to the program from 2019 to 2020, the average total time spent per patient per year dropped from 145 minutes in 2019 to 109 minutes in 2020.

Services included assessment of medication adherence, adverse drug reaction consultation, lab monitoring, patient counseling on initiation of a DMT, shared decision making, and follow-up visits.

“The KPWA MS Pharmacy Program plays an integral role in the care of patients with MS. The MS clinical pharmacists ensure patients are well informed about their DMT options and are fully educated about selected treatment,” the investigators noted.

A report on an outpatient MS clinic at Emory Healthcare, Atlanta, described how use of specialty pharmacist services resulted in a 49% reduction in time to treatment initiation with fingolimod. The time decreased from 83.9 days to 42.9 days following the introduction of specialty pharmacist services.

“Integration of a clinical pharmacy specialist in the therapeutic management of MS patients is crucial to early intervention with disease-modifying therapy,” the investigators noted.

A report on the specialty pharmacy services provided at Johns Hopkins MS Precision Medicine Center of Excellence, Baltimore, described an evaluation of 708 assessments between July 2019 and June 2020. Results showed that the vast majority (98%) of patients reported no missed days from work or school due to MS-related symptoms and that 99.3% reported no hospitalizations due to MS relapses, which are both key measures of MS treatment adherence.
 

High patient satisfaction

Patients reported high satisfaction with the in-house pharmacy on the National Association of Specialty Pharmacy’s patient satisfaction survey. In the survey, the average score was 82, compared with 79 for external specialty pharmacies.

“Moreover, patients were highly satisfied with the services provided at the pharmacy and were likely to continue receiving their comprehensive pharmacy care at our institution,” the researchers reported.

The study “highlights the value of pharmacists’ involvement in patient care and supports the need for continuation of integrated clinical services in health system specialty pharmacy,” the investigators noted.

CMSC President Scott D. Newsome, DO, director of the Neurosciences Consultation and Infusion Center at Green Spring Station, Lutherville, Maryland, and associate professor of neurology at Johns Hopkins University School of Medicine, said that as a clinician, he is highly satisfied with the specialty pharmacy services for MS at Johns Hopkins.

“Our pharmacists are fantastic in communicating with the prescriber if something comes up related to medication safety or they are concerned that the patient isn’t adhering to the medication,” Dr. Newsome said.

He noted that in addition to helping to alleviate the burden of a myriad of tasks associated with prescribing for patients with MS, specialty pharmacists may have an important impact on outcomes, although more data are needed.

“Having a specialty pharmacy involved in the care of our patients can help navigate the challenges associated with the process of obtaining approval for DMTs,” he said. “We know how important it is to expedite and shorten the time frame from writing the prescription to getting the person on their DMT.”
 

Telemedicine, other models

Although integrated specialty pharmacist services may seem out of reach for smaller MS clinics, the use of telemedicine and other models may help achieve similar results.

“A model I have seen is having pharmacists split their time between a specialty pharmacy and the MS clinic,” said Dr. Montgomery.

“A telemedicine model can also be utilized, in which a pharmacist can reach out to patients by telephone or through video visits. This would allow a pharmacist to be utilized for multiple clinics or as an MS specialist within a specialty pharmacy,” she added.

Whether provided in house or through telemedicine, a key benefit for clinicians is in freeing up valuable time, which has a domino effect in improving quality all around.

“In addition to improving safety outcomes, specialty pharmacists help with the allocation of clinic staff to other clinic responsibilities, and the utilization of services by patients results in more resources allocated for their care,” Dr. Montgomery said.

Naila Makhani, MD completed medical school training at the University of British Columbia (Vancouver, Canada). This was followed by a residency in child neurology and fellowship in MS and other demyelinating diseases at the University of Toronto and The Hospital for Sick Children (Toronto, Canada). Concurrent with fellowship training, Dr. Makhani obtained a Masters’ degree in public health from Harvard University. Dr. Makhani is the Director of the Pediatric MS Program at Yale and the lead investigator of a multi-center international study examining outcomes following the radiologically isolated syndrome in children.

Q1. Could you please provide an overview of Radiologically Isolated Syndrome ?

A1. Radiologically Isolated Syndrome (RIS) was first described in adults in 2009. Since then it has also been increasingly recognized and diagnosed in children. RIS is diagnosed after an MRI of the brain that the patient has sought for reasons other than suspected multiple sclerosis-- for instance, for evaluation of head trauma or headache. However, unexpectedly or incidentally, the patient’s MRI shows the typical findings that we see in multiple sclerosis, even in the absence of any typical clinical symptoms. RIS is generally considered a rare syndrome.

Q2. You created Yale Medicine’s Pediatric Multiple Sclerosis program which advocates for the eradication of MS. What  criteria defines a rare disease? Does RIS meet these criteria? And if so, how?

A2. The criteria for a rare disease vary, depending on the reference. In the US, a rare disease is defined as a condition that affects fewer than 200,000 people, in total, across the country.  By contrast, in Europe, a disease is considered rare if it affects fewer than one in every 2,000 people within the country’s population.

In the case of RIS, especially in children, we suspect that this is a rare condition, but we don't know for sure, as there have been very few population-based studies. There is one large study that was conducted in Europe that found one case of RIS among approximately 5,000 otherwise healthy children, who were between 7 and 14 years of age.  I think that's our best estimate of the overall prevalence of RIS in children. Using that finding, it likely would qualify as a rare condition, although, as I said, we really don't know for sure, as the prevalence may vary among different populations or age groups.

Q3. How do you investigate and manage RIS in children? What are some of the challenges?  

A3. For children with radiologically isolated syndrome, we usually undertake a comprehensive workup. This includes a detailed clinical neurological exam to ensure that there are no abnormalities that would, for instance, suggest a misdiagnosis of multiple sclerosis or an alternative diagnosis. In addition to the brain MRI, we usually obtain an MRI of the spinal cord to determine whether there is any spinal cord involvement. We also obtain blood tests. We often analyze spinal fluid as well, primarily to exclude other alternative processes that may explain the  MRI findings. A key challenge in this field is that there are currently no formal guidelines for the investigation and management of children with RIS. Collaborations within the pediatric MS community are needed to develop such consensus approaches to standardize care.

Q4. What are the most significant risk factors that indicate children with RIS could one day develop multiple sclerosis?

A4.This is an area of active research within our group. So far, we've found that approximately 42% of children with RIS develop multiple sclerosis in the future; on average, two years following their first abnormal MRI. Therefore, this is a high-risk group for developing  multiple sclerosis in the future. Thus far, we've determined that in children with RIS, it is the presence of abnormal spinal cord imaging and an abnormality in spinal fluid – namely, the presence of oligoclonal bands – that are likely the predictors of whether these children could develop MS in the future. a child’s possible development 

Q5. Based on your recent studies, are there data in children highlighting the potential for higher prevalence  in one population over another?

A5. Thus far, population-based studies assessing RIS, especially in children, have been rare and thus far have not identified particular subgroups with increased prevalence. We do know that the prevalence of multiple sclerosis varies across different age groups and across gender. Whether such associations are also present for RIS is an area of active research.

Naila Makhani, MD completed medical school training at the University of British Columbia (Vancouver, Canada). This was followed by a residency in child neurology and fellowship in MS and other demyelinating diseases at the University of Toronto and The Hospital for Sick Children (Toronto, Canada). Concurrent with fellowship training, Dr. Makhani obtained a Masters’ degree in public health from Harvard University. Dr. Makhani is the Director of the Pediatric MS Program at Yale and the lead investigator of a multi-center international study examining outcomes following the radiologically isolated syndrome in children.

Q1. Could you please provide an overview of Radiologically Isolated Syndrome ?

A1. Radiologically Isolated Syndrome (RIS) was first described in adults in 2009. Since then it has also been increasingly recognized and diagnosed in children. RIS is diagnosed after an MRI of the brain that the patient has sought for reasons other than suspected multiple sclerosis-- for instance, for evaluation of head trauma or headache. However, unexpectedly or incidentally, the patient’s MRI shows the typical findings that we see in multiple sclerosis, even in the absence of any typical clinical symptoms. RIS is generally considered a rare syndrome.

Q2. You created Yale Medicine’s Pediatric Multiple Sclerosis program which advocates for the eradication of MS. What  criteria defines a rare disease? Does RIS meet these criteria? And if so, how?

A2. The criteria for a rare disease vary, depending on the reference. In the US, a rare disease is defined as a condition that affects fewer than 200,000 people, in total, across the country.  By contrast, in Europe, a disease is considered rare if it affects fewer than one in every 2,000 people within the country’s population.

In the case of RIS, especially in children, we suspect that this is a rare condition, but we don't know for sure, as there have been very few population-based studies. There is one large study that was conducted in Europe that found one case of RIS among approximately 5,000 otherwise healthy children, who were between 7 and 14 years of age.  I think that's our best estimate of the overall prevalence of RIS in children. Using that finding, it likely would qualify as a rare condition, although, as I said, we really don't know for sure, as the prevalence may vary among different populations or age groups.

Q3. How do you investigate and manage RIS in children? What are some of the challenges?  

A3. For children with radiologically isolated syndrome, we usually undertake a comprehensive workup. This includes a detailed clinical neurological exam to ensure that there are no abnormalities that would, for instance, suggest a misdiagnosis of multiple sclerosis or an alternative diagnosis. In addition to the brain MRI, we usually obtain an MRI of the spinal cord to determine whether there is any spinal cord involvement. We also obtain blood tests. We often analyze spinal fluid as well, primarily to exclude other alternative processes that may explain the  MRI findings. A key challenge in this field is that there are currently no formal guidelines for the investigation and management of children with RIS. Collaborations within the pediatric MS community are needed to develop such consensus approaches to standardize care.

Q4. What are the most significant risk factors that indicate children with RIS could one day develop multiple sclerosis?

A4.This is an area of active research within our group. So far, we've found that approximately 42% of children with RIS develop multiple sclerosis in the future; on average, two years following their first abnormal MRI. Therefore, this is a high-risk group for developing  multiple sclerosis in the future. Thus far, we've determined that in children with RIS, it is the presence of abnormal spinal cord imaging and an abnormality in spinal fluid – namely, the presence of oligoclonal bands – that are likely the predictors of whether these children could develop MS in the future. a child’s possible development 

Q5. Based on your recent studies, are there data in children highlighting the potential for higher prevalence  in one population over another?

A5. Thus far, population-based studies assessing RIS, especially in children, have been rare and thus far have not identified particular subgroups with increased prevalence. We do know that the prevalence of multiple sclerosis varies across different age groups and across gender. Whether such associations are also present for RIS is an area of active research.

Dr Joseph Berger of the Perelman School of Medicine in Philadelphia discusses abstracts from ECTRIMS 2021 focusing on the use of disease-modifying therapies (DMTs) in patients with relapsing-remitting multiple sclerosis.

Dr Berger discusses ULTIMATE I and ULTIMATE II results, in which ublituximab — a novel monoclonal antibody — improved annualized relapse rates, Multiple Sclerosis Functional Composite scores, and percentages of patients with no evidence of disease activity compared to teriflunomide.

Dr Berger also highlights a study that examined the association between serum neurofilament light (NfL) levels and disease progression in patients on natalizumab. Although NfL levels were significantly reduced after initiation of therapy, no differences were evident between progressors and nonprogressors.

Next, he examines 3-year data from the CASTING study, which assessed ocrelizumab in patients who had a suboptimal response to one or two previous DMTs. Follow-up analysis showed that patients who received ocrelizumab had consistently low disease activity throughout the study period; mean Expanded Disability Status Scale (EDSS) scores, annualized relapse rates, and no evidence of disease activity were also stable.

Dr Berger concludes with a comparative analysis of patients who started on or switched to dimethyl fumarate or teriflunomide. Dimethyl fumarate showed more favorable outcomes in time to relapse, time to EDSS worsening, and sensitivity analysis.

Use of cannabis is common in patients with multiple sclerosis (MS), especially for the treatment of MS-related spasticity, new research suggests. Findings from a survey conducted through a large registry in 2020 showed that 31% of patients with MS reported trying cannabis to treat their symptoms – and 20% reported regular use.

Spasticity was reported by 80% as the reason why they used cannabis, while pain was cited as the reason by 69% and sleep problems/insomnia was cited by 61%.

Investigators noted that the new data reflect the latest patterns of use amid sweeping changes in recreational and medical marijuana laws.

“Interest in the use of cannabis for managing MS symptoms continues to increase as more data become available and access becomes easier,” co-investigator Amber Salter, PhD, associate professor, UT Southwestern Medical Center, Dallas, told attendees at the 2021 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC).
 

Administration routes vary

The survey was conducted through the longitudinal North American Research Committee on Multiple Sclerosis (NARCOMS) Registry, a voluntary, self-report registry for patients with MS. Of 6,934 registry participants invited to participate, 3,249 (47%) responded. The majority of responders were women (79%) and the mean age was 61 years. About 63% were being treated with disease-modifying therapies.

Overall, 31% of respondents reported having used cannabis to treat their MS symptoms. In addition, 20% reported regular current cannabis use, with an average use of 20 days in the past month. As many as 40% of the current users reported using cannabis daily.

“In general we saw some small differences in current users, who tended to include more males; have higher spasticity, pain, and sleep symptoms; and [were] more likely to be unemployed and younger,” Dr. Salter said.

The most common forms of cannabis administration were smoking (33%) and eating (20%). In addition, 12% reported vaporizing cannabis with a highly concentrated material, 11% administered cannabis sublingually, and 11% reported swallowing it.

Further, 8% reported vaporizing cannabis as a dried flower, 5% used it topically, and 1% reported drinking it.

Of note, the definition of “cannabis/marijuana” in the study excluded hemp cannabidiol (CBD) or products marketed as CBD only.
 

Consistent use

The most common reason for use by far was spasticity (80%). This was followed by for pain (69%) and sleep/insomnia problems (61%). Among users, 37% reported doing so to treat all three of those problems.

Regarding other symptoms, 36% used cannabis for anxiety, 24% for depression, 18% for overactive bladder, 17% for nausea or gastrointestinal problems, 16% for migraine or headaches, 14% for tremors, and 6% for other purposes.

The vast majority (95%) reported cannabis to be very or somewhat helpful for their symptoms.

Among the 69% of respondents who reported not using cannabis for their MS symptoms, the most commonly cited reasons were a lack of evidence on efficacy (40%) or safety (27%), concerns of legality (25%), lack of insurance coverage (22%), prohibitive cost (18%), and adverse side effects.

Surprisingly, the dramatic shift in the legalization of cannabis use in many states does not appear to be reflected in changes in cannabis use for MS, Dr. Salter said.

“We conducted an anonymous NARCOMS survey a couple of years prior to this survey, and our results are generally consistent. There’s been a small increase in the use and an acceptance or willingness to consider cannabis, but it’s relatively consistent,” she said.

“Despite the changes in access, the landscape hasn’t really changed very much in terms of evidence of the effects on MS symptoms, so that could be why,” Dr. Salter added.

Most patients appear to feel comfortable discussing their cannabis use with their physician, with 75% reporting doing so. However, the most common primary source of medical guidance for treating MS with cannabis was “nobody/self”; for 20%, the source for medical guidance was a dispensary professional.

As many as 62% of respondents reported obtaining their cannabis products from dispensaries, while other sources included family/friend (18%) or an acquaintance (13%). About 31% reported their most preferred type of cannabis to be equal parts THC and cannabidiol, while 30% preferred high THC/low cannabidiol (30%).
 

Mirrors clinical practice findings

Commenting on the study, Laura T. Safar, MD, vice chair of Psychiatry at Lahey Hospital and Medical Center and assistant professor of psychiatry at Harvard Medical School, Boston, said the findings generally fall in line with cannabis use among patients with MS in her practice.

“This is [consistent] with my general experience: A high percentage of my patients with MS are using cannabis with the goal of addressing their MS symptoms that way,” said Dr. Safar, who was not involved with the research.

One notable recent change in patients’ inquiries about cannabis is their apparent confidence in the information they’re getting, she noted. This is a sign of the ever-expanding sources of information – but from sources who may or may not have an understanding of effects in MS, she added.

“What seems new is a certain level of specificity in the information patients state – regardless of its accuracy. There is more technical information widely available about cannabis online and in the dispensaries,” said Dr. Safar.

“A lot of that information may not have been tested scientifically, but it is presented with an aura of truth,” she said.

While misconceptions about cannabis use in MS may not be new, “the conviction with which they are stated and believed seems stronger,” even though they have been validated by questionably expert sources, Dr. Safar noted.

She pointed out that psychiatric effects are among her patients’ notable concerns of cannabis use in MS.

“Cannabis use, especially daily use in moderate to large amounts, can have negative cognitive side effects,” she said. “In addition, it can have other psychiatric side effects: worsening of mood and anxiety, apathy, and anhedonia, a lack of pleasure or enjoyment, and a flattening of the emotional experience.”
 

Countering misinformation

Dr. Safar said she works to counter misinformation and provide more reliable, evidence-based recommendations.

“I educate my patients about what we know from scientific trials about the potential benefits, including possible help with pain, excluding central pain, and with spasticity,” she said. Dr. Safar added that she also discusses possible risks, such as worsening of cognition, mood, and anxiety.

On the basis of an individual’s presentation, and working in collaboration with their neurologist as appropriate, Dr. Safar said she discusses the following issues with the patient:

• Does cannabis make sense for the symptoms being presented?
• Has the patient received benefit so far?
• Are there side effects they may be experiencing?
• Would it be appropriate to lower the cannabis dose/frequency of its use?
• If a patient is using cannabis with an objective that is not backed up by the literature, such as depression, are they open to information about other treatment options?

The study was sponsored by GW Research. Dr. Salter has conducted research for GW Pharmaceuticals companies. Dr. Safar has disclosed no relevant financial relationships.

One notable recent change in patients’ inquiries about cannabis is their apparent confidence in the information they’re getting, she noted. This is a sign of the ever-expanding sources of information – but from sources who may or may not have an understanding of effects in MS, she added.

“What seems new is a certain level of specificity in the information patients state – regardless of its accuracy. There is more technical information widely available about cannabis online and in the dispensaries,” said Dr. Safar.

“A lot of that information may not have been tested scientifically, but it is presented with an aura of truth,” she said.

While misconceptions about cannabis use in MS may not be new, “the conviction with which they are stated and believed seems stronger,” even though they have been validated by questionably expert sources, Dr. Safar noted.

She pointed out that psychiatric effects are among her patients’ notable concerns of cannabis use in MS.

“Cannabis use, especially daily use in moderate to large amounts, can have negative cognitive side effects,” she said. “In addition, it can have other psychiatric side effects: worsening of mood and anxiety, apathy, and anhedonia, a lack of pleasure or enjoyment, and a flattening of the emotional experience.”
 

Countering misinformation

Dr. Safar said she works to counter misinformation and provide more reliable, evidence-based recommendations.

“I educate my patients about what we know from scientific trials about the potential benefits, including possible help with pain, excluding central pain, and with spasticity,” she said. Dr. Safar added that she also discusses possible risks, such as worsening of cognition, mood, and anxiety.

On the basis of an individual’s presentation, and working in collaboration with their neurologist as appropriate, Dr. Safar said she discusses the following issues with the patient:

• Does cannabis make sense for the symptoms being presented?
• Has the patient received benefit so far?
• Are there side effects they may be experiencing?
• Would it be appropriate to lower the cannabis dose/frequency of its use?
• If a patient is using cannabis with an objective that is not backed up by the literature, such as depression, are they open to information about other treatment options?

Use of cannabis is common in patients with multiple sclerosis (MS), especially for the treatment of MS-related spasticity, new research suggests. Findings from a survey conducted through a large registry in 2020 showed that 31% of patients with MS reported trying cannabis to treat their symptoms – and 20% reported regular use.

Spasticity was reported by 80% as the reason why they used cannabis, while pain was cited as the reason by 69% and sleep problems/insomnia was cited by 61%.

Investigators noted that the new data reflect the latest patterns of use amid sweeping changes in recreational and medical marijuana laws.

“Interest in the use of cannabis for managing MS symptoms continues to increase as more data become available and access becomes easier,” co-investigator Amber Salter, PhD, associate professor, UT Southwestern Medical Center, Dallas, told attendees at the 2021 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC).
 

Administration routes vary

The survey was conducted through the longitudinal North American Research Committee on Multiple Sclerosis (NARCOMS) Registry, a voluntary, self-report registry for patients with MS. Of 6,934 registry participants invited to participate, 3,249 (47%) responded. The majority of responders were women (79%) and the mean age was 61 years. About 63% were being treated with disease-modifying therapies.

Overall, 31% of respondents reported having used cannabis to treat their MS symptoms. In addition, 20% reported regular current cannabis use, with an average use of 20 days in the past month. As many as 40% of the current users reported using cannabis daily.

“In general we saw some small differences in current users, who tended to include more males; have higher spasticity, pain, and sleep symptoms; and [were] more likely to be unemployed and younger,” Dr. Salter said.

The most common forms of cannabis administration were smoking (33%) and eating (20%). In addition, 12% reported vaporizing cannabis with a highly concentrated material, 11% administered cannabis sublingually, and 11% reported swallowing it.

Further, 8% reported vaporizing cannabis as a dried flower, 5% used it topically, and 1% reported drinking it.

Of note, the definition of “cannabis/marijuana” in the study excluded hemp cannabidiol (CBD) or products marketed as CBD only.
 

Consistent use

The most common reason for use by far was spasticity (80%). This was followed by for pain (69%) and sleep/insomnia problems (61%). Among users, 37% reported doing so to treat all three of those problems.

Regarding other symptoms, 36% used cannabis for anxiety, 24% for depression, 18% for overactive bladder, 17% for nausea or gastrointestinal problems, 16% for migraine or headaches, 14% for tremors, and 6% for other purposes.

The vast majority (95%) reported cannabis to be very or somewhat helpful for their symptoms.

Among the 69% of respondents who reported not using cannabis for their MS symptoms, the most commonly cited reasons were a lack of evidence on efficacy (40%) or safety (27%), concerns of legality (25%), lack of insurance coverage (22%), prohibitive cost (18%), and adverse side effects.

Surprisingly, the dramatic shift in the legalization of cannabis use in many states does not appear to be reflected in changes in cannabis use for MS, Dr. Salter said.

“We conducted an anonymous NARCOMS survey a couple of years prior to this survey, and our results are generally consistent. There’s been a small increase in the use and an acceptance or willingness to consider cannabis, but it’s relatively consistent,” she said.

“Despite the changes in access, the landscape hasn’t really changed very much in terms of evidence of the effects on MS symptoms, so that could be why,” Dr. Salter added.

Most patients appear to feel comfortable discussing their cannabis use with their physician, with 75% reporting doing so. However, the most common primary source of medical guidance for treating MS with cannabis was “nobody/self”; for 20%, the source for medical guidance was a dispensary professional.

As many as 62% of respondents reported obtaining their cannabis products from dispensaries, while other sources included family/friend (18%) or an acquaintance (13%). About 31% reported their most preferred type of cannabis to be equal parts THC and cannabidiol, while 30% preferred high THC/low cannabidiol (30%).
