TARRYTOWN, N.Y., July 29, 2014 /PRNewswire/ -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that the U.S. Food and Drug Administration (FDA) has approved EYLEA ® (aflibercept) Injection for the treatment of Diabetic Macular Edema (DME). The recommended dosage of EYLEA in patients with DME is 2 milligrams (mg) every two months (8 weeks) after five initial monthly injections. Although EYLEA may be dosed as frequently as 2 mg every 4 weeks, additional efficacy was not demonstrated when EYLEA was dosed every 4 weeks compared to every 8 weeks. "Diabetic macular edema is a leading cause of vision loss among working-age adults in the U.S., and we are pleased to be able to offer a new treatment option to these patients," said George D. Yancopoulos, M.D., Ph.D., Chief Scientific Officer of Regeneron and President of Regeneron Laboratories. "Our clinical studies have demonstrated that treatment with EYLEA can help improve and maintain vision with every 8 week dosing after 5 initial monthly doses. EYLEA is the first VEGF inhibitor approved for dosing on a less than monthly basis for the treatment of DME." The approval of EYLEA in DME was based on the one-year data from the Phase 3 VISTA-DME and VIVID-DME studies of 862 patients, which compared EYLEA 2 mg given monthly, EYLEA 2 mg given every two months (after five initial monthly injections), or macular laser photocoagulation (at baseline and then as needed). In the DME studies, after one year, the mean changes in Best Corrected Visual Acuity (BCVA), as measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) chart for the monthly and every two month EYLEA groups, were statistically significantly improved compared to the control group and were similar to each other. Across both trials, patients in both EYLEA dosing groups gained, on average, the ability to read approximately two additional lines on an eye chart compared with almost no change in the control group.
