Clinical Results and FDA approvalThe FDA approved Lemtrada in November 2014, based on the results of two large, phase III clinical trials that confirmed its ability to significantly reduce relapse rates over two years over standard subcutaneous dosing of Rebif® (interferon beta-1a, EMD Serono Inc. and Pfizer). One of the studies also suggested that Lemtrada may significantly reduce worsening of disability.
