Cambridge, Mass., September 20, 2017 – bluebird bio, Inc. (Nasdaq: BLUE), a clinical-stage company committed to developing potentially transformative gene therapies for severe genetic diseases and T cell-based immunotherapies for cancer, today announced that it has appointed Mary Lynne Hedley, Ph.D. to its Board of Directors.


“I’m thrilled to welcome Mary Lynne to the Board,” said Nick Leschly, chief bluebird. “Since founding TESARO in 2010, she has shepherded that company from a clinical stage to a commercial stage, and has experience in bringing novel therapies to patients in need. As we continue to progress our four clinical programs, her broad executive experience, from clinical research through operations and commercialization, will be an invaluable resource for the growing bluebird team.”


“bluebird bio is a clear leader in the development of gene therapies for patients with severe genetic diseases, and has shown tremendous promise with its BCMA program in immuno-oncology,” said Dr. Hedley. “I’m excited to have the opportunity to work closely with the bluebird management team to help bring the promise of their transformative therapies to patients in need across multiple products and markets.”


Mary Lynne Hedley, Ph.D., co-founded TESARO, Inc., in 2010 and since that time, has served as the company’s President and as a member of its board of directors. Prior to founding TESARO, Dr. Hedley served as Executive Vice President of Operations and Chief Scientific Officer of Abraxis BioScience. She served as Executive Vice President of Eisai Corporation of North America from January 2008 until July 2009, following the company's acquisition of MGI PHARMA in January 2008. Dr. Hedley served in various positions at MGI PHARMA from 2004 through its acquisition in January 2008, most recently as Executive Vice President and Chief Scientific Officer. Prior to that, Dr. Hedley co-founded and served as the President and Chief Executive Officer of ZYCOS, which was acquired by MGI PHARMA in 2004.


Dr. Hedley completed two consecutive postdoctoral fellowships at Harvard University and earned her doctoral degree in immunology from the University of Texas, Southwestern Medical Center and her Bachelor of Science degree in microbiology from Purdue University. She serves on the Board of Directors of Millendo Therapeutics Inc. and Youville Place, an assisted living facility. She served on the Board of Directors of Receptos, Inc.
