On December 5, 2019, the United States Food and Drug Administration (FDA) announced that they had approved the applications from three separate pharmaceutical companies for the first generic versions of Gilenya® (fingolimod) capsules for the treatment of relapsing forms of multiple sclerosis (MS) in adult patients. Approved in September 2010, Gilenya was the first oral drug available for the long-term treatment of relapsing-remitting MS. Generic treatments carry the same benefits and risks of the initially approved medication. While this medication has been shown to slow disease activity, such as reducing the frequency of relapses as well as reducing the number of lesions as shown on magnetic resonance imaging (MRI), Gilenya’s potential side effects and adverse events include a temporary slowing of the heart rate, edema (swelling) behind the eye, and liver changes. Usually occurring in patients with weakened immune systems, progressive multifocal leukoencephalopathy (PML) is a rare but serious brain infection that could potentially occur. Along with some of the other long-term treatments for MS, PML has been reported in a small number of individuals taking Gilenya.
