The decision to reduce our workforce in support of a more focused set of priorities was made following a detailed review of the needs and capabilities of our organization, and we are grateful to every bluebird who has helped realize our founding vision of making gene therapy a reality for patients and families impacted by severe genetic diseases.”

As part of the restructuring, bluebird plans to further sharpen its focus on the ongoing commercial launches of LYFGENIA, ZYNTEGLO and SKYSONA to enable continued launch acceleration while the Company evaluates opportunities to increase its cash resources.
