In the version of this article initially published, it was reported that GlaxoSmithKline's (GSK's) EpiNova was one of several “biotech-like ideas” that “have been known to fizzle in pharma hands”; in fact, EpiNova has not “fizzled” but is in its second year of operation as a discovery performance unit of GSK focusing on epigenetic approaches to autoimmune disease. The error has been corrected in the HTML and PDF versions of the article.
