Real-World Effectiveness and Safety of Cladribine in Multiple Sclerosis: Longitudinal Data From the Nationwide Registry in Argentina

OBJECTIVE

The aim was to evaluate patient profiles, effectiveness and safety of cladribine (CLAD) in patients with relapsing-remitting multiple sclerosis in Argentina.

METHODS

This was a substudy included in RelevarEM (MS and neuromyelitis optica registry in Argentina, NCT03375177). Patients with MS who received CLAD tablets and were followed up for at least 24 months were included. Clinical evaluations every 3 months collect information about: a) clinical relapses; b) progression of physical disability, evaluated through Expanded Disability Status Scale, and c) new lesions found in the magnetic resonance imaging. Lymphopenia was evaluated during the follow-up and defined as grade 1: absolute lymphocyte count (ALC) 800-999/μL; grade 2: ALC 500-799/μL; grade 3: ALC 200-499/μL and grade 4: ALC <200/μL.

RESULTS

A total of 240 patients were included from 19 centers from Argentina. The mean annualized relapse rate during the 12-month pre-CLAD initiation was 1.19 ± 0.56 versus 0.22 ± 0.18 at month 12 and 0.19 ± 0.15 at month 24 (P < 0.001). A total of 142 (59.2%) fulfilled the criteria of disease activity during the 12 months before treatment initiation, whereas 27 (11.3%) fulfilled it at month 12 and 38 (15.8%) at month 24, P < 0.001. Regarding no evidence of disease activity (NEDA), 202 (84.2%) patients achieved NEDA status at month 12 and 185 (77%) at month 24. The most frequent incidence density of lymphopenia for course 2 observed was also for grade 1, 6.1 (95% confidence interval [CI] = 5.5-7.1). The overall incidence density of lymphopenia grade 4 was 0.1 (95% CI = 0.06-0.19).

CONCLUSION

This information will help when choosing the best treatment option for Argentinean patients.

Multiple Sclerosis Multidisciplinary Care: A National Survey and Lessons for the Global Community

BACKGROUND

Access to, standardization and reimbursement of multidisciplinary care for people with MS (PwMS) is lacking in many countries. Therefore, this study aims to describe the current multidisciplinary care for people with MS (PwMS) in Belgium and identify benefits, needs and future perspectives METHODS: A survey for PwMS questioned various aspects of MS and viewpoints on care. For MS nurses (MSN) and neurologists, employment, education, job-content, care organization and perspectives were inquired. Descriptive and univariate statistics were performed RESULTS: The PwMS survey comprised 916 respondents with a mean age of 46±12.7 years and 75,4 % of the respondents being female. The majority of the participants had relapsing remitting MS (60.8 %) and the mean patient determined disease steps (PDDS) was 2.0 (IQR=3). 65.3 % and 60.4 % of the PwMS reported having access to a multidisciplinary team (MDT) or MSN. Access to an MSN was associated with more frequent disease modifying treatment (p=.015), spasticity (p=.042) and gait treatment (p=.035), but also more physiotherapy (p=.004), driver's license adjustment (p<.001) and a higher employment rate (p=.004). MDT access was associated with more frequent symptomatic bladder treatment (p=.047), higher physiotherapy rate (p<.001), higher work- (p=.002), insurance- (p<.001) and home support measures (p=.019). PwMS without an available MDT more often indicated that MS care needs improvement (p<.001). MSN's (n = 22) were mainly funded through various budgets, including hospital and neurology practice budgets. Finally, 69 % and 75 % neurologists (n = 62) working without an MSN or MDT stated a need of such support and 61 % agreed that MDT's should be organized at hospital-network level CONCLUSION: MDT and MSN availability may enhance medical and socio-economic support for PwMS. Guidelines, alignment and reimbursement are needed.

Burden of treatment and quality of life in relapsing remitting multiple sclerosis patients under early high efficacy therapy in Argentina: Data from the Argentinean registry

The objective of this study was to describe and compare the burden of treatment (BOT) and the quality of life (QoL) in early high efficacy therapy (HET) vs. escalation therapy in relapsing remitting multiple sclerosis (RRMS) patients included in RelevarEM, the Argentinean registry of MS (RelevarEM, NCT 03,375,177).

METHODS

cross sectional study conducted between September and December 2022. Participating patients were adults, RRMS patients who initiated (during the last three years) their treatment with a HET (natalizumab, ocrelizumab, alemtuzumab, cladribine) or with escalation treatment (beta interferon, glatiramer acetate, teriflunomide, dimethyl fumarate or fingolimod). Clinical and demographic aspect were collected. QoL and BOT was measured with the validated to Spanish MusiQol and BOT questionnaire. Propensity score (PS)-based nearest-neighbor matching was applied to homogenize groups. Comparisons were be done using a linear regression analysis model stratified by matched pairs, with BOT and QoL assessments as main outcomes.

RESULTS

269 patients were included in the analysis, mean age 33.7 ± 5.7 years, 193 (71.7 %) were female. A total of 136 patients were on early HET while 133 were on escalation therapy. In the entire group the mean total BOT score (±SD) was 48.5 ± 15.3 while in the group of patients receiving early HET we observed that the mean BOT score (±SD) was 43.5 ± 12.2 vs. 54.3 ± 13.3 in escalation treatment (p < 0.0001). Regarding the score QoL (±SD), in the entire sample we observed a global score of 77.4 ± 11.2. When we stratified groups, in HET (±SD) it was 81.3 ± 14 vs. 74.1 ± 18.3 in escalation therapy (p = 0.0003).

CONCLUSION

in this multicenter study that included 269 patients from Argentina we observed in early HET a significantly lower BOT and higher QoL than patients receiving escalation therapy.

Multi-actor system dynamics in access to disease-modifying treatments for multiple sclerosis in Southeast Asia: A regional survey and suggestions for improvement

BACKGROUND

Despite the global availability of multiple sclerosis (MS) treatments, accessing and financing them in Southeast Asia (SEA) remains a challenge. This descriptive survey-based study aimed to describe the current state of MS treatment access and local access dynamics within this region.

METHODS

The survey questionnaire, comprising of 15 closed-ended and five open-ended questions, was developed by three neurologists with expertise in MS and routine MS patient management, or had training in neuroimmunology. Questionnaire development was guided by the recent Atlas of MS and in alignment with the Access to Treatment framework, focusing on MS diagnosis and treatment issues in SEA. Fifteen neurologists experienced in managing MS across the region were identified as key informants for this study.

RESULTS

All fifteen neurologists participated in the survey via email and videoconferencing between January 2020 and February 2023, which included the following countries: Brunei, Cambodia, Indonesia, Malaysia, Myanmar, Lao PDR, Philippines, Singapore, Thailand, Timor-Leste, and Vietnam. All had at least five years of experience in managing MS patients and six had previously completed a neuroimmunology fellowship programme. SEA countries showed disparities in healthcare financing, availability of neurologists, MS treatments, and investigative tools. Access to MS disease-modifying treatments (DMTs) is hindered by high cost, lack of MS specialists, and weak advocacy efforts. On-label DMTs are not listed as essential medicines regionally except for interferon beta1a and teriflunomide in Malaysia. On-label monoclonals are available only in Malaysia, Singapore, and Thailand. Generic on-label DMTs are unavailable due to lack of distributorship and expertise in using them. Off-label DMTs (azathioprine, methotrexate, and rituximab) predominate in most SEA countries. Other challenges include limited access to investigations, education, and knowledge about DMTs among general neurologists, and absence of registries and MS societies. Patient champions, communities, and MS organisations have limited influence on local governments and pharmaceutical companies. Despite its increasing prevalence, there is a lack of concerted priority setting due to MS being perceived as a rare, non-communicable disease.

CONCLUSION

This study highlights the distinct dynamics, challenges, and research gaps within this region, and provides suggestions to improve MS diagnosis, education, and medicine access.

Multiple sclerosis care units in Latin America: Consensus recommendations about its objectives and functioning implementation

OBJECTIVE

Currently, there are several reasons to promote worldwide the concept of multiple sclerosis care units (MSCU) for a better management of affected patients. Ideally, the MSCU should have some human and technical resources that distinguish and improve the care of affected patients; however, local, and regional aspects should be considered when recommending how these units should operate. The objective of these consensus recommendations was to review how MSCU should work in Latin America to improve long-term outcomes in MS patients.

METHODS

A panel of neurology experts from Latin America dedicated to the diagnosis and care of MS patients gathered virtually during 2019 and 2020 to carry out a consensus recommendation about objectives and functioning implementation of MSCU in Latin America. To achieve consensus, the methodology of "formal consensus-RAND/UCLA method" was used.

RESULTS

Recommendations focused on the objectives, human and technical resources, and the general functioning that MSCU should have in Latin America.

CONCLUSIONS

The recommendations of these consensus guidelines attempt to optimize the health care and management of MS patients by setting how MSCU should work in our region.
