BACKGROUND: Immune checkpoint inhibitors (ICIs) represent a novel class of agents approved for the treatment of several cancers and progressive multifocal leukoencephalopathy (PML). However, due to the risk of autoimmune side effects, their use in people with autoimmune diseases such as multiple sclerosis (MS) has been limited. OBJECTIVE: To characterize outcomes in a cohort of adults with MS who received ICIs. METHODS: A single-center retrospective review of medical record data was performed for people with MS treated with ICIs. RESULTS: Seven people with MS were identified, with a mean (SD) age at ICI use of 55.4 (13.7) years and a mean MS duration of 18.2 (12.2) years. Six were treated for cancer; 1 was treated for PML. After mean (SD) follow-up of 1.76 (2.15) years after ICI, outcomes are: no evidence of disease (2), residual metastatic disease (1), death due to cancer (1), death due to PML (1), and lost to follow-up (2). Notably, 0 out of 7 patients experienced an MS relapse; two out of six had new asymptomatic demyelinating magnetic resonance imaging lesions. In the three patients with expanded disability status scale (EDSS) scores at baseline and follow-up, EDSS remained stable (mean delta 0.13). CONCLUSION: In this cohort, no people with MS experienced clinical relapses and one-third experienced asymptomatic radiological activity following ICI treatment.

Background

Many women with multiple sclerosis (MS) report fluctuating symptoms across their menstrual cycle. Oral contraceptives (OCs) alter hormonal levels across the menstrual cycle. While cyclic OCs administer hormones for 21 days, followed by a week of placebo, continuous OCs can administer continuous doses of hormones for up to 3 months. Previous studies have suggested that OC use is associated with lower MS-related inflammation. We hypothesized that due to reduced hormonal fluctuations, women with MS might experience less inflammatory activity (clinical relapses+MRI) on continuous OCs than on cyclic OCs.

Methods

We performed a retrospective analysis of prospectively collected data. For women with MS aged 18-50 seen at the UCSF Center for MS and Neuroinflammation, we extracted data on OC use from the Electronic Medical Records (EMR). All variables were confirmed using manual clinical chart review. We identified 19 women with relapsing forms of MS on continuous OCs and matched them (2:1 when possible) to women on cyclic OCs for OC formulation, age, MS duration and DMT type. Inflammatory activity in the two groups was then compared using log-rank tests (time to new relapse, new T2-weighted lesion formation, and gadolinium-enhancing lesion formation) and t-tests (annualized relapse rate). We also performed subgroup analyses in women with at least 1 year (N = 28) and 2 years (N = 21) of clinical observation. A power calculation was performed.

Results

There was no difference in time to relapse (p = 0.50) between continuous and cycling OC users. However, continuous OC users showed a statistical trend to longer time to T2 lesion formation (p = 0.09) and longer time to contrast-enhancing lesion formation (p = 0.05). In patients with at least 1 year of observation, there was a significant difference in time to T2 lesion formation (p = 0.03) and time to contrast-enhancing lesion formation (p = 0.02).

Conclusion

In this exploratory study, women on continuous OCs showed a trend towards less inflammatory activity on MRI relative to women on cyclic OCs. This difference was not reflected in relapse rates. We estimate that 342 patients would be required for an adequately powered cohort study to evaluate such an effect. Our findings provide reassurance that for women using continuous OCs to alleviate menstrual fluctuations in symptoms, there is not an increase in MS-related inflammatory activity.

Background

Teleneurology for multiple sclerosis (MS) care was considered feasible, but utilization was limited.

Objective

To describe how the existing teleneurology populations at two academic MS Centers changed during the COVID-19 pandemic.

Methods

In this cross-sectional study, we captured all in-person and teleneurology visits at two academic MS Centers between January 2019 and April 2020. We compared group differences between the Centers, and COVID-related changes using T-, chi-squared Kruskal-Wallis and Fisher exact tests.

Results

2268 patients completed 2579 teleneurology visits (mean age 48.3 ± 13.3 years, 72.9% female). Pre-COVID, the Centers' teleneurology populations were similar for age, sex, MS type, and disability level (all p > 0.1), but differed for race (96.5% vs 80.7% white, p ≤ 0.001), MS treatment (49.1% vs 32.1% infusible, p ≤ 0.001), and median distance from Center (72 vs 186 miles, p ≤ 0.001). Post-COVID, both Centers' teleneurology populations had more black (12.7% vs 4.37%, p ≤ 0.001) and local (median 34.5 vs 102 miles, p ≤ 0.001) patients.

Conclusion

Teleneurology visits in 2019 reflected the organizational and local teleneurology reimbursement patterns of our Centers. Our post-COVID-19 changes illustrate the potential for payors and policy to change disparities in access to, or utilization of, remote care. Patients' perception of care quality and value following this shift warrants study.

Background

There are numerous challenges to treating co-occurring symptoms in multiple sclerosis (MS).

Objective

To pilot the feasibility of a novel symptom management platform, CoachMS, to monitor MS symptoms (bladder function, ambulation, and mood: BAM) and respond to changes in real-time.

Methods

In this 12-week randomized controlled pilot trial, participants' symptoms were monitored using weekly questionnaires and remote ambulatory monitoring (Fitbit Flex2®). Behavioral change principles used included shared goal setting at 2 weeks. Between weeks 2-12, the CoachMS group received targeted contact and interventions if symptoms worsened; the control group were treated through usual clinic practice. Our outcomes were feasibility (retention, adherence and acceptability; primary) and proportion of recommended treatments pursued (secondary); efficacy was explored.

Results

Of 21 participants enrolled, 13 (62%) completed the study; protocol adherence was excellent. CoachMS participants demonstrated greater follow-through with clinical recommendations than controls (OR 9.3, 95% CI (0.9, 97.6)). As a cohort, each BAM symptom tended to improve. Suicidality was detected in one control participant, resulting in urgent evaluation and hospitalization.

Conclusions

The innovative CoachMS platform was feasible and acceptable in this cohort with baseline BAM symptoms. It could represent an accessible, cost-effective tool to monitor MS symptoms in real-time; a larger trial is planned.

BACKGROUND: A majority of women with multiple sclerosis (MS) are diagnosed prior to menopause, yet their experiences during this transition are not well characterized. OBJECTIVES: To explore associations between mental health, sleep, and other quality of life metrics, and vasomotor symptoms (VMSs) in ambulatory, menopausal women with MS. METHODS: A secondary analysis was performed of baseline data from two trials enrolling ambulatory peri/postmenopausal women with MS: NCT02710214 (N = 24, bothersome VMS) and NCT04002934 (ongoing, N = 35, myelin repair). Measures analyzed were 36-Item Short-Form Survey (SF-36) (primary scale: general mental health), subjective sleep quality (Pittsburg Sleep Quality Index), VMS (daily diary, interference), mood (Center for Epidemiologist Studies-Depression Scale (CES-D)), walking impairment (timed 25-foot walk (T25FW)), and global disability (Expanded Disability Status Scale (EDSS)). RESULTS: Participants characteristics (N = 59) were: mean age 51.8 years (SD = 3.4), mean disease duration 11.3 years (SD = 7.6), median EDSS 3.0 (IQR = 2.0-4.0). Mental health was associated with better sleep quality (rho = -0.41, p = 0.019) and better mood (rho = -0.75, p < 0.001), but not with EDSS or T25FW (rho < 0.20, p > 0.10). Worse sleep quality also correlated with more frequent VMS (rho = 0.41, p = 0.02) and VMS interference (rho = 0.59, p < 0.001). CONCLUSIONS: Findings suggest that optimizing sleep quality, mood, and hot flash quantity/interference could substantially improve mental health in menopausal women with MS-and highlight an important care gap in this population.

To evaluate radiologic and clinical inflammatory activity in women with MS during pregnancy and postpartum. We performed a retrospective analysis of prospectively collected clinical and MRI reports for women who became pregnant while followed at the University of California, San Francisco MS Center between 2005 and 2018. Proportion of brain MRIs with new T2-hyperintense or gadolinium enhancing (Gd+) lesions (primary outcome) and annualized relapse rate (ARR; secondary) were compared before and after pregnancy. We identified 155 pregnancies in 119 women (median Expanded Disability Status Scale [EDSS] 2.0). For the 146 live birth pregnancies, prepregnancy ARR was 0.33; ARR decreased during pregnancy, particularly the third trimester (ARR 0.10, p = 0.017) and increased in the 3 months postpartum (ARR 0.61, p = 0.012); and 16% of women experienced a clinically meaningful increase in EDSS. Among 70 pregnancies with paired brain MRIs available, 53% had new T2 and/or Gd+ lesions postpartum compared with 32% prepregnancy (p < 0.001). Postpartum clinical relapses were associated with Gd+ lesions (p < 0.001). However, even for patients without postpartum relapses, surveillance brain MRIs revealed new T2 and/or Gd+ lesions in 31%. Protective effects of exclusive breastfeeding for ≥3 months (odds ratio = 0.3, 95% confidence interval 0.1-0.9) were observed for relapses. Building on previous reports of increased relapse rate in the first 3 months postpartum, we report a significant association between inflammation on MRI and this clinical activity. We also detected postpartum radiologic activity in the absence of relapses. Both clinical and radiologic reassessment may inform optimal treatment decision-making during the high-risk early postpartum period.

Background and objectives

Patients with multiple sclerosis (MS) transition from oral sphingosine-1-receptor (S1P) modulators to anti-CD20 therapies for several circumstances. Optimal timing of this transition is uncertain, given competing concerns of rebound disease activity and ensuring immune reconstitution. The objective of this study was to evaluate the relationship between inflammatory activity and the transition period from fingolimod to anti-CD20 therapies in a real-world MS cohort.

Methods

Medical records were reviewed for all patients at our center transitioning from fingolimod to rituximab or ocrelizumab between 2010 and October 2020. Time periods reviewed were the following: before fingolimod discontinuation, interval between fingolimod and anti-CD20 treatments, and after the first anti-CD20 infusion. The primary outcome was clinical relapses; MRI activity, time to absolute lymphocyte count (ALC) recovery, and infections were secondary. Clinical and demographic factors significant in univariable analyses were included in multivariable analyses.

Results

Transition data were available for 108 patients (68.5% women, 68.5% relapsing-remitting MS, mean age 44.6 years). The median (interquartile range) interval between fingolimod and anti-CD20 therapy was 28 (1-115.2) days. Six of 51 patients (11.8%) with intervals >1 month and 0/57 patients with shorter intervals experienced a relapse (MRI confirmed) within 6 months of fingolimod discontinuation. In the year following anti-CD20 initiation, 4/108 patients (3.7%) experienced a relapse (median 214.5 days after infusion). An additional 7% of those undergoing contrast-enhanced MRIs developed Gd+ lesions. ALC normalized following treatment switch in 89/92; the interval between treatments was unrelated to ALC recovery or infection.

Discussion

Delaying anti-CD20 start to monitor ALC after S1P modulator discontinuation may not be necessary and could increase rebound risk. ALC monitoring could instead occur after a rapid switch to anti-CD20 treatment.

Introduction

Self-administered in-home digital therapeutics could expand access to cognitive rehabilitation for individuals with multiple sclerosis (MS), over half of whom experience cognitive impairment (CI). However, feasibility in an MS population must be clarified. This study was conducted to assess the feasibility of deploying a videogame-like digital treatment for CI in MS, including initial efficacy and barriers to adherence.

Methods

In this pilot study, 21 participants with MS completed an in-clinic baseline neurological evaluation. Cognitive tests included paper-and-pencil Brief International Cognitive Assessment for Multiple Sclerosis [BICAMS-which included the Symbol Digit Modalities Test (SDMT)] and other unsupervised tablet-based tests (including Match: an unsupervised test of executive functions and processing speed, developed at UCSF; and the Cogstate MS Battery). Participants then completed an in-home, tablet-based, videogame-like investigational digital treatment (Project: EVO™) for 25 min daily, 5 days weekly, for 4 weeks. This was followed by a repeat in-clinic evaluation.

Results

Of the 21 participants (mean [standard deviation, SD] age 53.8 [11.6] years, median Expanded Disability Status Scale (EDSS) 2.5 [SD 2.0, IQR [2-3.5]]) enrolled to use the digital therapeutic at home (mean [SD] SDMT z score: - 0.21 [1.16]), 18 completed the study, during which they completed an average of 19.7 days (median [SD]: 20.5 [8.4]). Overall, 78% of these 18 participants completed 75% of prescribed days (i.e., at least 15), and 50% completed all 20 days or more. Over the 4-week period, scores of processing speed improved significantly (based on one-sided t test), including SDMT (p = 0.003) and Match (p = 0.006). The Cogstate DET test (psychomotor function) also increased (p = 0.006). Mean increase in SDMT was 3.6 points. Male sex, not being employed, and higher baseline anxiety all were significantly associated with greater improvement in SDMT over the 4-week period. Interestingly, lower baseline cognitive scores were associated with greater number of sessions completed (e.g., SDMT: p = 0.003, R² = 0.44). Adjusting for employment, a proxy for time available, did not significantly improve the model fit.

Discussion

Deploying an in-home digital tool to improve processing speed in MS is feasible, and shows preliminary efficacy. A larger, randomized controlled clinical trial is ongoing.

To determine the transfer of rituximab, an anti-CD20 monoclonal antibody widely used for neurologic conditions, into mature breast milk. Breast milk samples were collected from 9 women with MS who received rituximab 500 or 1,000 mg intravenous once or twice while breastfeeding from November 2017 to April 2019. Serial breast milk samples were collected before infusion and at 8 hours, 24 hours, 7 days, and 18-21 days after rituximab infusion in 4 patients. Five additional patients provided 1-2 samples at various times after rituximab infusion. The median average rituximab concentration in mature breast milk was low at 0.063 μg/mL (range 0.046-0.097) in the 4 patients with serial breast milk collection, with an estimated median absolute infant dose of 0.0094 mg/kg/d and a relative infant dose (RID) of 0.08% (range 0.06%-0.10%). Most patients had a maximum concentration at 1-7 days after infusion. The maximum concentration occurred in a woman with a single breast milk sample and was 0.29 μg/mL at 11 days postinfusion, which corresponds with an estimated RID of 0.33%. Rituximab concentration in milk was virtually undetectable by 90 days postinfusion. We determined minimal transfer of rituximab into mature breast milk. The RID for rituximab was less than 0.4% and well below theoretically acceptable levels of less than 10%. Low oral bioavailability would probably also limit the absorption of rituximab by the newborn. In women with serious autoimmune neurologic conditions, monoclonal antibody therapy may afford an acceptable benefit to risk ratio, supporting both maternal treatment and breastfeeding.
