Editas Medicine ($EDIT) has nabbed former VP of rare disease clinical development Dr. Gerald Cox from Sanofi Genzyme ($SNY) to become its CMO. The move comes as the genome editing company plans to move into the clinic next year. The Cambridge, MA-based company nabbed another pharma exec earlier this year, the former VP of genetically defined diseases and genomics at Bristol-Myers Squibb ($BMY), Charles Albright, to serve as its CSO.
