Introduction: Fingolimod 0.5 mg is an orally active sphingosine 1-phosphate receptor modulator approved for use in adults with relapsing multiple sclerosis (MS). The efficacy and safety profile of fingolimod has been well characterized in a large clinical development program. Here, we report the safety and tolerability of fingolimod in relapsing-remitting MS (RRMS) patients from Latin America. Methods: A total of 162 patients with RRMS, predominantly from Latin American countries (138/162), were enrolled in this 16-week, single treatment arm, open-label, multi-center study.
