Abstract

Affecting 2.5 million people worldwide, multiple sclerosis (MS) is one of the main causes of acquired disability among young adults. In French West Indies (FWI), where MS has arisen from the end of the 80's, a low therapeutic response to interferons beta1 (IFN beta1) in patients of African descent, restrains the therapeutic options. Fingolimod is a Sphingosine-1-Phosphate receptor modulator whose efficacy in the treatment of MS has recently been shown in three phase III studies. Nevertheless, data are currently lacking concerning the use of Fingolimod among populations of African descent, particularly in a real-world setting. Efficacy and safety information collected during the first two years of follow-up have been analysed retrospectively for all patients in whom Fingolimod treatment was introduced in FWI between its marketing date and December 2015. Fifty-two consecutive patients with a relapsing remitting MS started Fingolimod therapy in the FWI, according to the European guidelines. After 24 months, 40 patients were still receiving the treatment. The average Annualized Relapse Rate (ARR) dropped by 81%, and 72.5% of patients remained free from disability progression during the 24 months on Fingolimod. MS remained controlled (according NEDA 3 criteria) for 41% of patients who were still on therapy at 24 months. Nine participants presented with a moderate or major side effect. Unlike IFN beta1 therapy, Fingolimod appears to be effective in Afro-Caribbean patients in a real-world setting with a similar benefit to what has been observed in phase III studies in more selected populations.
