Change Type: Correction
Change Details: In the illustration that accompanies this article, the structures of regorafenib and sorafenib were incorrectly drawn. In both structures, a double bond was omitted from the central phenyl ring so that it appeared as a 1,3-cyclohexadiene. The figure has been corrected in both the HTML and PDF versions of this News & Views.
