Fingolimod reduces annualized relapse rate by 1.17 per patient-year in pediatric MSFingolimod Reduces Relapse Rates for Children with Multiple Sclerosis

Key Takeaway
Consider fingolimod for reducing relapses in pediatric MS, but note EDSS stability was not statistically significant.

This meta-analysis evaluated the efficacy and persistence of fingolimod in pediatric multiple sclerosis (Ped-MS). The analysis included 585 patients and compared outcomes to baseline before treatment, with follow-up of approximately 24 months.

The primary outcome was the mean difference in annualized relapse rate (ARR). Fingolimod was associated with a significant decrease in ARR, with a mean difference of -1.17 relapses per patient-year (95% CI -1.76 to -0.59). The secondary outcome, Expanded Disability Status Scale (EDSS) score, showed a mean difference of -0.27 from baseline, but this was not statistically significant (p = 0.24; 95% CI -0.86 to 0.32).

Regarding treatment persistence, 79.8% of patients remained on fingolimod after nearly 24 months. Adverse events reported included leukopenia/lymphopenia, headache, cough, and infections. Serious adverse events and discontinuation rates were not reported.

The authors note that fingolimod significantly reduced relapse rates and stabilized EDSS, though the EDSS change was not significant. Limitations were not reported. Clinically, these findings support considering fingolimod for relapse reduction in pediatric MS, but the lack of significant EDSS improvement should temper expectations regarding disability progression.

How this fits prior evidence

This meta-analysis extends prior evidence on MS treatments by focusing on pediatric patients, a population often underrepresented. It confirms the relapse-reducing benefit of fingolimod, consistent with the modest diagnostic performance of serum neurofilament light chain for disease activity, suggesting that clinical outcomes like ARR remain important. It contrasts with mesenchymal stem cell transplantation, which showed no significant EDSS improvement in progressive MS, as fingolimod also did not significantly change EDSS. The high persistence rate (79.8%) adds practical insight, addressing gaps in standardized treatment algorithms noted for radiologically isolated syndrome.

Researchers looked at how the medication fingolimod affects children with multiple sclerosis (Ped-MS). They analyzed data from 585 patients over a period of about 24 months to see how the treatment changed their condition compared to their status before starting the medicine.

The results showed that patients taking fingolimod had a significant decrease in their annualized relapse rate. Specifically, there was a reduction of 1.17 relapses per patient-year. While the medication helped reduce these relapses, it did not show a statistically significant change in the Expanded Disability Status Scale (EDSS), which measures physical disability.

Most patients, about 79.8 percent, stayed on the medication for nearly two years. Some common side effects reported during treatment included headache, cough, infections, and low white blood cell counts. Because this was a meta-analysis of existing data, it provides a broad look at the drug's performance but does not replace a personal consultation with a doctor to determine the best treatment plan.

What this means for you:
Fingolimod significantly reduced annual relapse rates in children with multiple sclerosis over a 24-month period.

Common questions

How effective is fingolimod for children with multiple sclerosis?

The study showed that fingolimod significantly reduced the annualized relapse rate in children. Patients saw a decrease of 1.17 relapses per patient-year compared to their baseline. While it helped reduce these relapses, it did not show a significant change in the Expanded Disability Status Scale (EDSS) during the 24-month period.

What are the common side effects of fingolimod?

Patients taking fingolimod reported some common side effects, including headache and cough. Other reported issues included infections and low white blood cell counts (leukopenia or lymphopenia). You should talk to a doctor to discuss how these risks apply to your specific situation.

How many children stayed on the medication during the study?

The data showed that approximately 79.8 percent of patients remained on fingolimod after nearly 24 months of treatment. This suggests that a large majority of the children in the study were able to continue with the therapy for at least two years.

BACKGROUND: Selecting the optimum disease-modifying therapy (DMT) for pediatric multiple sclerosis (Ped-MS) poses a significant challenge and requires special attention. If untreated or treated inappropriately, PED-MS can lead to cognitive impairment affecting the patient's whole life and causing irreversible sequelae. OBJECTIVE: To comprehensively review the efficacy and safety of fingolimod, the only FDA-approved DMT in Ped-MS. METHODS: Our PRISMA-based review included a systematic search of PubMed, Embase, Web of Science, and Scopus. The primary endpoint for meta-analysis was the mean difference (MD) in annualized relapse rate (ARR) after fingolimod compared to before treatment. Secondary outcomes were the MD of Expanded Disability Status Scale (EDSS) and the proportion of Ped-MS patients persisting on fingolimod. RESULTS: A total of 2997 articles were identified from databases, and after screening and selection, 15 studies encompassing 585 patients were included in our systematic review. Fingolimod was associated with a significant ARR change of -1.17 relapses per patient-year (95% CI -1.76 to -0.59) from baseline. Fingolimod was not able to significantly decrease EDSS (p = 0.24) and showed a - 0.27 change from baseline (95% CI -0.86 to 0.32). After almost 24 months of fingolimod therapy, 79.8% of Ped-MS patients were still on fingolimod and did not switch their DMT. Overall adverse events ranged from 10.8% to 88%, with leukopenia/lymphopenia, headache, cough, and infections being the most reported. CONCLUSION: Fingolimod, with a convenient oral route of administration, showed a significant effect on ARR and stabilized EDSS. Most patients remained on this DMT after 24 months, which shows relatively favorable efficacy and acceptable safety.
