1039 ET - Regeneron Pharmaceuticals' Eylea franchise has known headwinds, but the magnitude of its miss in the U.S. may further rattle investors, say Evercore ISI analysts in a research note. The drug maker said sales of Eylea, both the original formulation and HD version, were affected by inventory issues and competition from biosimilars. What was not expected was yet another complete response letter from the FDA for the prefilled syringe in Eylea HD, say the analysts. "We expect a negative reaction as frustrations mount with the company's regulatory execution," say the analysts. Shares decline 7.1% to $567.62, making it the worst performer in the S&P 500 and Nasdaq 100. (denny.jacob@wsj.com; @pennedbyden)
