The Division of Drug Information (DDI) is CDER's focal point for public inquiries. We serve the public by providing information on human drug products and drug product regulation by FDA.
The U.S. Food and Drug Administration has completed its evaluation of a report of a patient who died after the first dose of multiple sclerosis drug Gilenya (fingolimod). The agency also has evaluated additional clinical trial and postmarket data for Gilenya, including reports of patients who died of cardiovascular events or unknown causes. FDA could not definitively conclude that Gilenya was related to any of the deaths. However, based on its reevaluation of the data, FDA remains concerned about the cardiovascular effects of Gilenya after the first dose. Data show that, although the maximum heart rate lowering effect of Gilenya usually occurs within 6 hours of the first dose, the maximum effect may occur as late as 20 hours after the first dose in some patients. For this reason, Gilenya is now contraindicated (FDA advises against its use) in patients with certain pre-existing or recent (within last 6 months) heart conditions or stroke, or who are taking certain antiarrhythmic medications.
