Multiple Sclerosis

Portaccio and colleagues explored this issue and concluded that disease progression independent of relapse activity (PIRA) was a major contributor of confirmed disability accrual (CDA) in early relapse after the onset of MS, with age being a major determinant in the way that CDA occurs. In a retrospective cohort analysis of 5169 patients with either clinically isolated syndrome or early relapsing-remitting MS who were assessed within 1 year of onset and followed-up for ≥ 5 years, PIRA accounted for 27.6% of disability-worsening events, whereas relapse-associated worsening accounted for 17.8% of events, with relapse-associated worsening being more frequent in younger (hazard ratio [HR] 0.87) and PIRA in older (HR 1.19; both P < .001) patients. Recognition of disease relapse or progression is not always simple in a complex disease, but failure to recognize these issues can result in long-term accumulation of economically important disability. Multiple other issues related to effective disease management also require effective juggling in routine care. Adherence to treatment, timing of DMT change, and interval between discontinuing a DMT and starting a different one continue to be critical concerns as well. Malpas and associates explored this issue and noted that the importance of adherence impact on disease control also relates to treatment interruption and timing of duration between stopping one DMT and starting another agent. The annualized relapse rate (ARR) and the rate of severe relapses was explored in a cohort of 685 people with MS and did not increase significantly after discontinuation of fingolimod in this population, but delaying the commencement of immunotherapy increased the risk for relapse. The ARR was not significantly different during and after fingolimod cessation (mean difference −0.06; 95% CI −0.14 to 0.01), with no severe relapses reported in the year prior to and after fingolimod cessation. However, delaying the recommencement of DMT, or if change in DMT was delayed from 2 to 4 months, vs beginning within 2 months (odds ratio 1.67; 95% CI 1.22-2.27) was associated with a higher risk for relapse. Discontinuation of DMT or treatment interruption also relates to planned or unplanned pregnancy in people with MS. In another study Portaccio and colleagues continued treatment with natalizumab until conception and then restarted treatment within 1 month after delivery. This reduced the risk for disease activity more than natalizumab cessation before conception or restarting 1 month after delivery in women with MS. No major developmental abnormalities were noted in the infants born of 72 pregnancies in 70 women with MS who were treated for at least 2 years. Specifically, relapses occurred in 29.4% of people with MS treated until conception vs 70.2% in those who discontinued prior to conception, after a mean follow-up of 6.1 years (P = .001), with timing of treatment cessation being the only predictor of relapses (HR 4.1; P = .003). No developmental abnormalities were observed in the infants.

Practical points for the treating clinician are many and continue to highlight the complexity of managing people with MS in the real world, with real issues from COVID-19 vaccination, SARS-CoV-2 infection, recognition or awareness of relapse, and the increased challenges of adherence and timing of DMT change and of DMT use relative to pregnancy. Data-driven, reliable, relevant information is critical to incorporate into routine care to enhance and optimize decision-making.

Key clinical point: Pregnancy may have a protective effect on the risk of developing multiple sclerosis (MS) in addition to a hypothesized reverse causality.

Major finding: Women with MS vs. women without any autoimmune disease were less likely to record the 18 pregnancy-related gynecological International Classification of Diseases 10th Revision codes, with strongest negative correlation observed for the supervision of normal pregnancy (adjusted P = 9.12 × 10⁻²⁷) and high-risk pregnancy (adjusted P = 2.49 × 10⁻¹²).

Study details: Findings are from a retrospective case-control study including women with newly diagnosed MS (n = 5720) and three control cohorts of women with newly diagnosed Crohn’s Disease (n = 6280), psoriasis (n = 26,729), and women without any of the three autoimmune diseases (n = 40,555).

Key clinical point: Progression independent of relapse activity (PIRA) is a major contributor of confirmed disability accrual (CDA) in early relapsing-onset multiple sclerosis (MS), with age being a major determinant of the way CDA occurs.

Major finding: PIRA accounted for 27.6% of disability worsening events, whereas relapse-associated worsening (RAW) accounted for 17.8% of events, with RAW being more frequent in younger (hazard ratio [HR] 0.87) and PIRA in older (HR 1.19; both P < .001) patients.

Study details: Findings are from a retrospective cohort analysis of 5169 patients with clinically isolated syndrome or early relapsing-remitting MS who were assessed within 1 year of onset and followed-up for ≥5 years.

Study details: Findings are from a retrospective cohort analysis of 5169 patients with clinically isolated syndrome or early relapsing-remitting MS who were assessed within 1 year of onset and followed-up for ≥5 years.

Disclosures: No source of funding was declared. Some authors declared serving on advisory boards or receiving grants, travel compensation, speaker honoraria, or lecture and consulting fees from various sources.

Key clinical point: Patients with multiple sclerosis (MS) show reduced neutralizing antibody (nAb) response to SARS-CoV-2 mRNA vaccine, with B-cell depleting therapies having a significant effect on vaccine efficacy.

Major finding: Patients with MS treated with B-cell depleting therapies vs. other or no therapy showed a >9-fold decrease in the nAb response (P < .001), with 61.5% of patients showing no detectable levels of nAb. B-cell depleting therapy (P < .0001) was associated with significantly reduced neutralization titer 50% values.

Study details: This was a prospective longitudinal study including 51 patients with MS who completed the vaccination course of BNT162b2 (Pfizer/BioNTech), mRNA-1273 (Moderna), or Ad26.COV2 (Johnson and Johnson) SARS-CoV-2 vaccine.

Disclosures: No source of funding was declared. TV Gyang reported serving as consultant and BM Segal reported serving as a consultant, moderator, and speaker and on data safety monitoring boards for various sources. The other authors declared no conflicts of interest.

Key clinical point: A favorable benefit-risk profile of ofatumumab vs. teriflunomide in recently diagnosed treatment-naive (RDTN) patients with relapsing multiple sclerosis (MS) highlights the possibility of ofatumumab being considered the first-line therapy in these patients.

Major finding: Ofatumumab vs. teriflunomide reduced the annual relapse rate (ARR), confirmed disability worsening at 6 months, and mean number of gadolinium-enhanced T1 lesions/magnetic resonance imaging scan by 50% (P < .001), 46% (P = .044), and 95% (P < .001), respectively, with a manageable and consistent safety profile.

Study details: This was a post hoc analysis of ASCLEPIOS I and II studies including 615 RDTN patients with relapsing MS who were randomly assigned to receive ofatumumab or teriflunomide for up to 30 months.

Disclosures: This study was funded by Novartis Pharma AG, Basel, Switzerland. The authors declared receiving lecture, consultancy, or speaker fees; travel grants; or personal compensation or serving as a steering committee members and on advisory boards for various sources, including Novartis Pharma AG. Some authors declared being employees of Novartis Pharma AG.
