About bluebird bio, Inc.

bluebird bio is pioneering gene therapy with purpose. From our
Cambridge, Mass., headquarters, we’re developing gene therapies for
severe genetic diseases and cancer, with the goal that people facing
potentially fatal conditions with limited treatment options can live
their lives fully. Beyond our labs, we’re working to positively disrupt
the healthcare system to create access, transparency and education so
that gene therapy can become available to all those who can benefit.

bluebird bio is a human company powered by human stories. We’re putting
our care and expertise to work across a spectrum of disorders by
researching cerebral adrenoleukodystrophy, sickle cell disease,
transfusion-dependent β-thalassemia and multiple myeloma using three
gene therapy technologies: gene addition, cell therapy and
(megaTAL-enabled) gene editing.

bluebird bio has additional nests in Seattle, Wash.; Durham, N.C.; and
Zug, Switzerland. For more information, visit bluebirdbio.com.
