Abstract：

INTRODUCTION:Fingolimod is a selective immunosuppressant that targets the S1P receptor, and is indicated in the treatment of aggressive relapsing-remitting multiple sclerosis (RRMS) and following treatment failure with first-order drugs. AIM:To investigate the safety and effectiveness of fingolimod under the conditions of routine clinical practice. PATIENTS AND METHODS:We conducted an observational study with prospective follow-up of patients with RRMS who received fingolimod from January 2011 until February 2014. Data assessed were the annualised relapse rate (ARR), disability measured by the Expanded Disability Status Scale (EDSS), magnetic resonance activity and the appearance of side effects. RESULTS:Our sample consisted of 122 patients, 79.5% of them females and with a mean age of 26.8 years. They were classified, according to the last treatment received, as being: naive (aggressive RRMS; n = 17), previous treatment failure (n = 67) and withdrawal of natalizumab due to risk of progressive multifocal leukoencephalopathy (n = 38). After a mean follow-up of 29.9 ± 15.9 months, the ARR and the appearance of new lesions with gadolinium enhancement were reduced in both the naive and the previous treatment failure groups. There were no differences between the various subgroups as regards the progression of EDSS or the time elapsed until the first attack or treatment failure. The risk of treatment failure is higher with a baseline EDSS > 3 (hazard ratio: 4.24; p = 0.001) and presence of IgM oligoclonal bands (hazard ratio: 2.45; p < 0.022). CONCLUSIONS:Fingolimod is an effective and well-tolerated drug under conditions of routine clinical practice. Having a baseline EDSS > 3 and IgM oligoclonal bands is predictive of a poor response to fingolimod. TITLE:Tratamiento de la esclerosis multiple remitente recurrente con fingolimod en la practica clinica habitual. :Introduccion. El fingolimod es un inmunosupresor selectivo dirigido contra el receptor SP-1, indicado en el tratamiento de la esclerosis multiple remitente recurrente (EMRR) agresiva y tras el fracaso del tratamiento con farmacos de primera linea. Objetivo. Investigar la seguridad y efectividad del fingolimod en condiciones de practica clinica habitual. Pacientes y metodos. Estudio observacional con seguimiento prospectivo de pacientes con EMRR que recibieron fingolimod desde enero de 2011 hasta febrero de 2014. Se evaluo la tasa anual de brotes (TAB), la discapacidad medida por la escala expandida del estado de discapacidad (EDSS), la actividad en la resonancia magnetica y la aparicion de efectos adversos. Resultados. Incluimos 122 pacientes, el 79,5% mujeres y con una edad media de 26,8 antilde;os. Se clasificaron segun el ultimo tratamiento recibido en: naive (EMRR agresiva; n = 17), fracaso a terapias previas (n = 67) y retirada de natalizumab por riesgo de leucoencefalopatia multifocal progresiva (n = 38). Tras un seguimiento medio de 29,9 ± 15,9 meses, se redujo de forma significativa la TAB y la aparicion de nuevas lesiones con realce de gadolinio en el grupo naive y el de fracaso a terapias previas. No ha habido diferencias en la evolucion de la EDSS ni en el tiempo hasta el primer brote o el fracaso terapeutico entre los diferentes subgrupos. El riesgo a fracaso terapeutico es mayor con la EDSS basal > 3 (hazard ratio: 4,24; p = 0,001) y presencia de bandas oligoclonales IgM (hazard ratio: 2,45; p < 0,022). Conclusiones. El fingolimod es un farmaco eficaz y seguro en la EMRR en condiciones de practica clinica habitual. Tener una EDSS basal > 3 y bandas oligoclonales IgM predice una mala respuesta al fingolimod.
