Abstract | BACKGROUND: METHODS: Of 147 patients who completed the 6-month core study, 143 entered the extension. Those originally randomized to placebo were re-randomized to fingolimod 1.25 mg or 0.5 mg. During the extension, all patients were switched to open-label fingolimod 0.5 mg. RESULTS: Magnetic resonance imaging (MRI) and relapse outcomes were maintained or improved in patients treated with fingolimod for 12 months versus those treated for 6 months. No new safety events were reported over 12 months of treatment. Infections occurred in similar proportions of continuously treated and switched patients, while cardiac and liver adverse events occurred in fewer continuously treated than switched patients. Four patients were aquaporin-4 (AQP4) antibody-positive, three of whom showed rapid disease exacerbations within 10 days of fingolimod initiation. CONCLUSION: Continuous fingolimod treatment for up to 12 months was associated with maintained or improved efficacy and a manageable safety profile, consistent with that previously seen. Results in a small number of patients suggest lack of benefit in AQP4 antibody-positive patients. Meaningful statistical interpretation was limited by the small sample size in each treatment group, owing to the number of patients who completed the core study. TRIAL REGISTRATION: ClinicalTrials.gov NCT00670449.
