bluebird bio Acquires Precision Genome Engineering, a Privately Held Gene-Editing Company

Acquisition brings Homing Endonuclease and MegaTAL gene-editing and novel cell signaling technologies with a broad range of potential therapeutic applications in gene therapy and cancer immunotherapies

CAMBRIDGE, Mass. & SEATTLE--(BUSINESS WIRE)--Jun. 30, 2014-- bluebird bio, Inc. (Nasdaq: BLUE), a clinical-stage company committed to developing potentially transformative gene therapies for severe genetic and orphan diseases, today announced the acquisition of Precision Genome Engineering, Inc., or Pregenen, a privately held biotechnology company headquartered in Seattle, Washington. Pregenen is a leader in the development of gene editing and cell signaling technologies with a broad range of potential therapeutic applications.

“We are excited to add Pregenen’s team and their unique gene editing platform to bluebird as it will further expand and lever our gene therapy product platform,” stated Nick Leschly, chief bluebird. “While we remain focused on driving our core programs forward, this acquisition represents a significant investment in our stated strategy to integrate emerging technologies that can enhance our ability to develop innovative and potentially transformative gene therapy and cancer immunotherapy products for patients.”

“Pregenen is a recognized leader in the development and reprogramming of novel Homing Endonuclease and MegaTAL based enzymes that provide a highly specific and efficient way to silence, edit, or insert genetic components” stated Co-founder Andrew Scharenberg M.D. “Teaming up with bluebird allows us to further expand and translate our gene editing and cell signaling technologies into potentially new and impactful human therapeutics, and provides an opportunity to complement bluebird’s established HSC and CAR-T cell product platforms to develop the next generation of gene therapy product candidates.”
Under the terms of the agreement, bluebird bio issued the former stakeholders of Pregenen 408,667 shares of bluebird common stock at closing, and paid or assumed approximately $4.9 million of current liabilities of Pregenen and its stakeholders. The former stakeholders of Pregenen are also eligible to receive up to an additional $15.0 million in cash upon the achievement of certain preclinical milestones as well as $20.1 million in cash upon achievement of certain clinical milestones and $99.9 million in cash upon the achievement of certain commercial milestones with respect to product candidates identified using Pregenen’s technology.

Conference Call and Webcast

bluebird bio will host a conference call at 4:30 pm EDT on Monday, June 30, 2014 to discuss the transaction. Investors may listen to the webcast of the conference call live on the "Calendar of Events" section of bluebird bio’s website, Alternatively, investors may listen to the call by dialing: (844) 825-4408 from locations in the U.S. and (315) 625-3227 from outside the U.S. The webcast replay will be available for at least 72 hours following the call.

About Homing Endonucleases (HE) -- also called Meganucleases (MN)

Homing Endonucleases (HE) are the most specific naturally occurring DNA cleaving enzymes yet discovered, employing an integrated DNA binding and cleavage mechanism to target DNA sequences greater than 20 base pairs in length. HEs are compact, non-repetitive, and use highly efficient cleavage chemistry, thus enabling “multiplex” gene editing: multiple genomic sequences can be targeted for modification using a single gene delivery vector. This offers the potential for improved efficacy by unlocking multiple mechanisms of action within gene and cell based therapies. HE’s unique biology promotes the editing or replacement of defective genes by leveraging the body’s natural cellular DNA repair mechanisms.

About MegaTALs

MegaTALs are a single-chain fusion enzyme that combines the natural DNA cleaving processes of Homing Endonucleases (HEs) with the DNA binding region of transcription activator-like (TAL) effectors. TALs are easily engineered proteins that recognize specific DNA sequences. This protein fusion architecture allows the generation of extremely active and highly specific and compact nucleases that are compatible with all current viral and non-viral cell delivery methods.

About bluebird bio, Inc.

bluebird bio is a clinical-stage company committed to developing potentially transformative gene therapies for severe genetic and orphan diseases. bluebird bio has two clinical-stage programs in development. The most advanced product candidate, Lenti-D, is in a recently-initiated phase 2/3 study, the Starbeam Study, for the treatment of childhood cerebral adrenoleukodystrophy (CCALD), a rare, hereditary neurological disorder affecting young boys. The next most advanced product candidate, LentiGlobin, is currently in two phase 1/2 studies, one in the US (the Northstar Study) and one in France (HGB-205), for the treatment of beta-thalassemia major. The phase 1/2 HGB-205 study also allows enrollment of patient(s) with sickle cell disease, and bluebird bio is planning a separate U.S. sickle cell disease trial (HGB-206).

bluebird bio also has an early-stage chimeric antigen receptor-modified T cell (CAR-T) program for oncology in collaboration with Celgene Corporation.

bluebird bio has operations in Cambridge, Massachusetts and Paris, France. For more information, please visit

About Precision Genome Engineering, Inc. (Pregenen)

Precision Genome Engineering, Inc., or Pregenen, is a Seattle-based, privately-held biotechnology company designing and engineering molecules critical to a new generation of gene and cell-based therapies for unmet medical needs. Pregenen has developed a proprietary DisplayArray™platform to reprogram TrueCut™Homing Endonucleases and related enzymes highly specific to single genomic targets. These enzymes are combined with other key technologies to modify cells and optimize their therapeutic potential. Pregenen has also developed a novel cell signaling system designed to provide pharmacological control over chimeric antigen receptor driven immunotherapies. Pregenen’s lead programs are in pre-clinical development. Pregenen was founded by researchers at the Seattle Children’s Research Institute, the Fred Hutchinson Cancer Research Center and the University of Washington.
