Regeneron, Sanofi-Aventis sue for declaration that dermatitis treatment Dupixent doesn’t infringe Amgen patent

Although Dupixent hasn’t been granted FDA approval as of yet, the drug has made it further than Amgen’s AMG-317, the code name for Amgen’s own IL-4 inhibitor developed during the 2000s, which failed in phase 2 clinical trials… The major impetus behind this suit was Sanofi-Aventis and Regeneron’s discovery that Amgen hired litigation counsel to assert the ‘487 patent and is also working on retaining experts. The plaintiffs believe that the only likely target for any potential Amgen infringement suit asserting the ‘487 patent would target Dupixent, “the only IL-4 inhibitor expected to come to market in the near future.”
