0855 GMT - Sanofi shares fall in European morning trading, while Regeneron Pharmaceuticals is sharply lower in U.S. premarket trading, after the companies reported mixed results from two late-stage trials of a respiratory drug they are jointly developing. Sanofi and Regeneron said drug candidate Itepekimab missed the key goal of a phase 3 trial, but met the primary objective in the other study. Paris-listed shares in Sanofi fall 5.8%, while Regeneron shares drop 12% in U.S. premarket trading. (adria.calatayud@wsj.com)
