Real-world experience of ocrelizumab in multiple sclerosis in a Spanish population.

OBJECTIVE: Pivotal trial have shown that patients with multiple sclerosis (MS) receiving ocrelizumab had better outcomes. However, data on ocrelizumab in clinical practice are limited. The aim of this study was to evaluate the preliminary safety profile and effectiveness of ocrelizumab treatment for multiple sclerosis (MS) in a real-world clinical setting. METHODS: We conducted a retrospective study including consecutive patients from nine public hospitals in south-eastern Spain who received ocrelizumab after it was approved. RESULTS: A total of 228 MS patients were included (144 with relapsing-remitting MS [RRMS], 25 secondary progressive MS [SPMS], and 59 primary progressive MS [PPMS]). Median follow-up period was 12 months (range, 1-32). No evidence of disease activity (NEDA) status at year 1 was achieved in 91.2% of the relapsing MS (RMS) population, while disability progression was detected in 37.5% of the PPMS patients (median follow-up period, 19 months). The most common adverse events reported were infusion-related reactions and infections, with the most common infections being urinary tract infections followed by upper respiratory infections and COVID-19. INTERPRETATION: The preliminary results in our real-world setting show that ocrelizumab presented excellent results in suppressing disease activity with a favorable and consistent safety profile.

Relapses and obstetric outcomes in women with multiple sclerosis planning pregnancy.

OBJECTIVE: To evaluate the effect of discontinuation of different disease-modifying therapies (DMTs) before pregnancy with respect to the occurrence of relapses and pregnancy outcomes. METHODS: Women with multiple sclerosis who desire to bear children were followed prospectively. Demographic data, clinical characteristics, and the information on the use of DMTs were collected. A multivariate analysis was used to assess the relationship between relapses and the prior use of different DMTs. RESULTS: The present study assessed 75 consecutive pregnancy plans (66 women), 65 of which resulted in pregnancy. The mean age of the participants was 32.1 ± 4.2 years, and the mean disease duration was 6.1 ± 4.2 years. No relapses before pregnancy were reported in the group of women who maintained their DMT until pregnancy confirmation, while 14 relapses were reported in 12/42 women (29%) who discontinued DMT before pregnancy. During pregnancy, patients on natalizumab or fingolimod before pregnancy had a higher rate of relapses. Most women restarted their previous DMT after delivery within the first trimester. The relapse rate in postpartum was 0.07. CONCLUSIONS: Disease-modifying therapies received influences the risk of relapse and disease progression from women who are planning pregnancy. The risk of relapse during pregnancy was significantly higher in the group of women treated with natalizumab or fingolimod compared to the group of women treated with interferon beta or glatiramer acetate. The postpartum risk of relapses was lower than that found in previous reports.

Multiple sclerosis prevalence and incidence in San Vicente del Raspeig, Spain.

BACKGROUND: Changes in the demographic epidemiology of multiple sclerosis (MS) may challenge the view of a latitudinal gradient in the distribution of MS. The objective of this study was to assess the incidence and prevalence of MS in addition to information on MS phenotypes and the use of disease modifying therapies (DMTs) in San Vicente del Raspeig in south eastern Spain. METHODS: This was a prospective epidemiological study of MS in San Vicente del Raspeig (population of 57,175 inhabitants based on the 2017 census) from 2005 to 2018. Multiple sources were used to identify MS cases. We considered as prevalent and incident cases all patients who satisfied either the criteria of Poser for clinically or laboratory-supported definite MS, or McDonald criteria. MS phenotypes were defined according to the 2013 revisions. RESULTS: For the prevalence data, 64 patients were identified. The non-adjusted prevalence was 111.9 (95% CI: 87.7-142.9) cases per 100,000 inhabitants; the prevalence was 159.3 cases per 100,000 inhabitants for women and 63.6 cases per 100,000 inhabitants for men. The female-to-male ratio was 2.6:1. The age-adjusted prevalence for the European standard population was 107 cases per 100,000 inhabitants. During the study period, the incidence was 5 cases per 100,000 inhabitants per year. Most patients were being treated with DMTs (81.3%). MS was active in at least 12.5% of patients. CONCLUSIONS: The results are consistent with the increased risk of MS in Spain observed over the last three decades, with growing prevalence rates that place the country in the high-risk prevalence zone.

Using a multidimensional unfolding approach to assess multiple sclerosis patient preferences for disease-modifying therapy: a pilot study.

PURPOSE: Multidimensional unfolding is a multivariate method to assess preferences using a small sample size, a geometric model locating individuals and alternatives as points in a joint space. The objective was to evaluate relapsing-remitting multiple sclerosis (RRMS) patient preferences toward key disease-modifying therapy (DMT) attributes using multidimensional unfolding. PATIENTS AND METHODS: A cross-sectional pilot study in RRMS patients was conducted. Drug attributes included relapse prevention, disease progression prevention, side-effect risk and route and schedule of administration. Assessment of preferences was performed through a five-card game. Patients were asked to value attributes from 1 (most preferred) to 5 (least preferred). RESULTS: A total of 37 patients were included; the mean age was 38.6 years, and 78.4% were female. Disease progression prevention was the most important factor (51.4%), followed by relapse prevention (40.5%). The frequency of administration had the lowest preference rating for 56.8% of patients. Finally, 19.6% valued the side-effect risk attribute as having low/very low importance. CONCLUSION: Patients' perspective for DMT attributes may provide valuable information to facilitate shared decision-making. Efficacy attributes were the most important drug characteristics for RRMS patients. Multidimensional unfolding seems to be a feasible approach to assess preferences in multiple sclerosis patients. Further elicitation studies using multidimensional unfolding with other stated choice methods are necessary to confirm these findings.

Rescue Therapy Using Rituximab for Multiple Sclerosis.

OBJECTIVES: The aim of the study was to describe the effectiveness and safety data of rituximab in a group of patients with relapsing-remitting multiple sclerosis (MS) treated with rituximab due to failure of previous treatments or concomitant autoimmune diseases. METHODS: This is an observational study. Rituximab was considered in case of failure of the second-line therapy, failure of the first-line therapy and a contraindication to second-line therapies, or concomitant autoimmune disease. Relapses, the Expanded Disability Status Scale, the EQ VAS, and magnetic resonance imaging activity were assessed. RESULTS: This study included 12 patients with relapsing-remitting MS. The mean (range) age of the patients was 35 (19-54) years. Ten patients were treated with rituximab because of treatment failure, and 2 patients were treated with rituximab because of the development of idiopathic thrombocytopenic purpura. The mean (range) follow-up duration after beginning rituximab was 40 (18-72) months. Rituximab was well tolerated, because no patient experienced serious adverse reactions or discontinued treatment. During treatment with rituximab, no patient suffered a clinical relapse, and magnetic resonance imaging activity was not detected. The Expanded Disability Status Scale scores improved in 11 of 12 patients and remained stable in 1 patient. The EuroQol visual analogue scale scores improved in 8 of 9 patients in whom the EuroQol visual analogue scale was assessed. CONCLUSIONS: Treatment with rituximab seems to be safe and effective for some patients with relapsing-remitting MS who have failed to respond to first- and second-line therapies and may also be a useful option for patients with concomitant autoimmune disorders.
