Multiple Sclerosis

Key clinical point: Female sex and progressive forms of multiple sclerosis (MS) are the prognostic factors for worsening lower urinary tract symptoms in patients with MS, with neurogenic lower urinary tract dysfunction being a contributor to disease progression.

Major finding: A higher bowel/bladder functional system (FS) score, indicating worsening symptoms and functions, was significantly associated with female vs male sex (P = .001) and progressive vs relapsing-remitting MS type (P ≤ .001), with each point increase in the bowel/bladder FS score during follow-up visit at 1 year being associated with an increased risk of worsening disability over the subsequent year (area under curve 0.63).

Study details: This prospective study evaluated 802 patients with clinically isolated syndrome or MS.

Disclosures: This research was funded by the National Multiple Sclerosis Society, US National Institutes of Health, and Valhalla Foundation.

Key clinical point: Decreased SARS-CoV-2 antibody level is the major contributor to breakthrough SARS-CoV-2 infection in vaccinated patients with multiple sclerosis (MS) on various disease modifying therapies (DMT), with the third dose significantly reducing the risk for infection.

Major finding: After the second vaccine dose, the only significant factor associated with the risk for breakthrough infection was low antibody level (hazard ratio [HR] 0.51; P < .001), with the third dose reducing the risk for infection by 56% (HR 0.44; P = .025) during the Omicron wave.

Study details: Findings are from a prospective study of 1705 patients with MS on various DMT who received 2 doses of BNT162b2 (BioNTech-Pfizer) (n = 1391) or mRNA-1273 (Moderna) (n = 314) SARS-CoV-2 vaccine, with most receiving the third dose.

Key clinical point: In ocrelizumab-treated patients with multiple sclerosis (MS), a third SARS-CoV-2 vaccine boosted the T-cell response, but had no additive effect on the maximal T-cell response.

Major finding: SARS-CoV-2-specific T-cell response in patients treated with ocrelizumab was comparable to those not treated with disease modifying therapy (DMT) and healthy controls (HC) after the second SARS-CoV-2 vaccination; however, the third SARS-CoV-2 vaccination had no additive effect on T-cell response, but it did induce a booster response (P < .05).

Study details: This was a prospective longitudinal study including patients with MS treated with ocrelizumab (n = 24), fingolimod (n = 12), or no DMT (n = 10) and HC (n = 12) who received three SARS-CoV-2 vaccine doses (BNT162b2 [BioNTech-Pfizer] or CX-024414 [Moderna]).

Key clinical point: Continuous siponimod treatment for up to >5 years showed sustained efficacy and a consistent safety profile in patients with secondary progressive multiple sclerosis (SPMS).

Major finding:  The risk for 6-month confirmed disability progression (CDP) was 22% lower (P = .0026) and confirmed worsening in cognitive processing speed was 23% lower (P = .0047) in patients who received continuous siponimod vs those who switched from placebo to siponimod. Siponimod had a manageable and consistent safety profile.

Study details: Findings are from the phase 3 EXPAND study including the extension phase that included 1220 of 1651 patients with SPMS from the core phase. In the extension phase, patients who had received placebo in the core phase switched to siponimod, whereas those who had received siponimod continued the same treatment.

Key clinical point: Teriflunomide is effective and well-tolerated in treatment-naive patients with relapsing-remitting multiple sclerosis (RRMS), with females with mild disease activity and lesser disability most likely to benefit.

Major finding: Overall, 79% of patients achieved No Evidence of Disease Activity 3 (NEDA) at 12 months, with the mean annualized relapse rate reducing significantly (P < .001), the mean Expanded Disability Status Scale (EDSS) score remaining stable (P = .658), and only 8.3% of patients discontinuing treatment because of adverse events. Male sex (hazard ratio [HR] 1.856; P < .017), frequent relapses before treatment (HR 3.056; P < .000), and a baseline EDSS score of ≥4 (HR 2.682; P < .004) were associated with the failure to achieve NEDA 3.

Study details: This was an observational cohort study including 217 treatment-naive patients with RRMS who were treated with teriflunomide.

Key clinical point: Women vs men with multiple sclerosis (MS) showed greater inflammatory disease activity up to menopausal age, whereas men vs women with MS showed greater disability accrual.

Major finding: Women vs men had a 16% higher relapse rate and a higher estimated marginal mean of annualized relapse rate (0.32 vs 0.28; P < .001); however, the difference disappeared after the age of 50 years. The deterioration in the Expanded Disability Status Scale (EDSS) points was higher in men vs women (0.065 vs 0.049 EDSS points per year; P = .0017), with men at a higher risk of reaching EDSS 4 (P < .001).

Study details: Findings are from an analysis of 9647 patients (3028 men and 6619 women) with MS from the Danish MS registry (DMSR) who received disease-modifying therapy and were followed-up for at least 1 year and two control visits.

Study details: Findings are from an observational study including 23 patients with MS, most of whom had completed the initial COVID-19 vaccine series prior to infection, were either untreated or treated with fingolimod/ocrelizumab, and received anti-SARS-CoV2-mAb (bamlanivimab/etesevimab, casirivimab/imdevimab, sotrovimab, or undocumented formulation) for treatment of active COVID-19 infection.

Disclosures: This study did not receive any funding. Some authors reported receiving consulting fees and research support from various sources.

Key clinical point: Serum neurofilament light chain (sNfL) could serve as an effective prognostic biomarker for long-term disability progression in patients with progressive multiple sclerosis (PMS).

Major finding: An sNfL value of >10.2 pg/mL at baseline differentiated long-term progressors and nonprogressors with a sensitivity of 75% and a specificity of 67% (adjusted odds ratio [aOR] 7.8; P = .01), and an increase of >5.1 pg/mL in the sNfL value from baseline to 6 years differentiated long-term progressors and nonprogressors with a sensitivity of 71% and a specificity of 86% (aOR 49.4; P = .008).

Study details: This was a 6-year prospective observational cohort study that included 51 patients with PMS who had participated in a 2-year phase 2, randomized, placebo-controlled trial of interferon-beta.

Disclosures: No external funding was received for this study. The authors declared no conflicts of interests.

Key clinical point: Switching to once every-6-weeks (QW6) dosing of natalizumab from a stable dosing of once every-4-weeks (QW4) was safe without any clinically meaningful loss of efficacy in most patients with relapsing-remitting multiple sclerosis (RRMS).

Major finding: The mean number of new or newly enlarging T2 hyperintense lesions at 72 weeks was 0.20 (95% CI 0.07-0.63) vs 0.05 (95% CI 0.01-0.22) with natalizumab QW6 vs QW4 dosing regimen, with two patients developing ≥25 lesions contributing to most of the excess lesions in the QW6 dosing regimen. The safety profile was similar for both the regimens.

Study details: Findings are from a phase 3b NOVA trial including 499 patients with RRMS on stable intravenous natalizumab QW4 dosing who were randomly assigned to continue QW4 (n  = 248) or switch to QW6 (n = 251) natalizumab dosing.

Disclosures: This study was funded by Biogen. Five authors reported being current or former employees or holding stocks in Biogen, and some authors reported receiving consulting or speakers’ fees, personal compensation, or serving as a steering committee or advisory board member for various sources.
