bluebird bio, Inc., based in Somerville, Massachusetts, is a biotechnology company that develops gene therapies for severe genetic disorders. The company is owned by investment funds managed by The Carlyle Group and SK Capital Partners.
One of the company's approved drugs is betibeglogene autotemcel (Zynteglo), which treats transfusion-dependent beta thalassemia (TDT), a rare genetic blood disorder, and has been approved for use by the European Medicines Agency.[1] The company has been criticized for the $1.8 million cost of the drug, which is the second most expensive drug in the world.[2][3][4]
The company is developing LentiGlobin[5] gene therapy for the treatment of sickle cell disease and cerebral adrenoleukodystrophy. It is also developing T cell product candidates to treat acute myeloid leukemia, Merkel-cell carcinoma, diffuse large B-cell lymphoma, and MAGEA4 solid tumors.

History

Perspective
The company was founded as Genetix Pharmaceuticals in April 1992 by MIT faculty members Philippe Leboulch and Irving London.[6]
From 2001 to 2005, Walter Ogier was chief executive officer of Genetix.[7] At that time, the company was focused on the development of LentiglobinTM for the treatment of sickle cell disease and thalassemia major (beta-thalassemia), the two most globally prevalent severe human genetic diseases.
In September 2010, preliminary results of clinical trials of LentiglobinTM at Hospital Necker in Paris, France, were published in Nature by Marina Cavazzana and company founder Philippe Leboulch. Stable transfusion (21 months) independence was successfully achieved by a patient with severe beta-thalassemia who had been treated with Lentiglobin 2 years earlier. This represented the first-ever long term correction of a major human genetic disease by gene therapy.[8]
Also in September 2010, the company was renamed bluebird bio and Nick Leschly was named chief executive officer.[9]
In June 2013, the company became a public company via an initial public offering, raising $116 million.[10][11]
In June 2014, the company acquired Precision Genome Engineering Inc. for up to $156 million.[12]
In November 2017, Celgene, now Bristol-Myers Squibb (BMS), announced a collaboration with bluebird bio regarding bb2121 Anti-BCMA chimeric antigen receptor T cell therapy.[13] In May 2020, the Food and Drug Administration (FDA) issued a refusal to file letter to BMS and bluebird bio's marketing application seeking approval of idecabtagene vicleucel (ide-cel) for patients with heavily pre-treated relapsed and refractory multiple myeloma.[14] In September 2020, the FDA accepted bluebird's marketing application for ide-cel in and established a PDUFA goal date of March 27, 2021.[15] Ide-cel is a BCMA-directed genetically modified autologous CAR-T-cell immunotherapy.
In August 2018, the company announced a collaboration with Regeneron Pharmaceuticals to discover, develop and commercialize new cell therapies for cancer.[16][17]
In November 2021, the company completed the corporate spin-off of 2seventy bio, focused on oncology.[18][19]
In 2022 and 2024, the company laid off 25-30% of its staff.[20]
In June 2025, investment funds managed by The Carlyle Group and SK Capital Partners acquired the company and increased its funding.[21][22]
