CAMBRIDGE, Mass.--(BUSINESS WIRE)--bluebird bio, Inc. (Nasdaq: BLUE) announced today that the European Medicines Agency (EMA) accepted the company’s marketing authorization application (MAA) for its investigational LentiGlobin™ gene therapy for the treatment of adolescents and adults with transfusion-dependent β-thalassemia (TDT) and a non-β0/β0 genotype.
LentiGlobin was previously granted an accelerated assessment by the Committee for Medicinal Products for Human Use (CHMP) of the EMA in July 2018, potentially reducing the EMA’s active review time of the MAA from 210 days to 150 days.
“People living with transfusion-dependent β-thalassemia require frequent blood transfusions that are life-saving but may lead to complications, including organ failure due to iron overload,” said David Davidson, M.D., chief medical officer, bluebird bio. “The acceptance of our marketing authorization application for LentiGlobin is a milestone that advances us toward our goal of providing to patients the first one-time gene therapy that addresses the underlying genetic cause of TDT. We share this important milestone with the patients, families and healthcare providers who made it possible through their participation in our pioneering clinical studies of LentiGlobin.”
The MAA for LentiGlobin is supported by data from the completed Phase 1/2 Northstar (HGB-204) study and the ongoing Phase 1/2 HGB-205 study as well as available data from the Phase 3 Northstar-2 (HGB-207) study and the long-term follow-up study LTF-303.
About Transfusion-Dependent β-Thalassemia
TDT is an
inherited blood disorder caused by a mutation in the β-globin gene,
which causes ineffective red blood cell production leading to severe
anemia. Supportive care for people with TDT consists of a lifelong
regimen of chronic blood transfusions to enable survival and suppress
symptoms of the disease, and iron chelation therapy to manage iron
overload that results from the transfusions.
Despite the availability of supportive care, many people with TDT experience serious complications and organ damage due to underlying disease and iron overload. By eliminating or reducing the need for blood transfusions, the long-term complications associated with TDT may be reduced.
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been successfully used to treat TDT and is currently the only available option with the potential to correct the genetic deficiency in TDT. Complications of allo-HSCT include a risk of treatment-related mortality, graft failure, graft-versus-host disease (GvHD) and opportunistic infections, particularly in patients who undergo non-sibling matched allo-HSCT.
About LentiGlobin
LentiGlobin is a one-time gene therapy
being studied as a potential treatment to address the underlying genetic
cause of TDT, which could eliminate or reduce the need for blood
transfusions.
bluebird bio’s clinical development program for LentiGlobin includes ongoing studies around the world with sites in Australia, Germany, Greece, France, Italy, Thailand, the United Kingdom and the United States. For more information visit: www.northstarclinicalstudies.com or clinicaltrials.gov using identifier NCT01745120.
In addition, bluebird is conducting a long-term safety and efficacy follow-up study (LTF-303) for people who have participated in bluebird bio-sponsored clinical studies of LentiGlobin for TDT and sickle cell disease.
The EMA previously granted Priority Medicines (PRIME) eligibility and Orphan Medicinal Product designation to LentiGlobin for the treatment of TDT. LentiGlobin is also part of the EMA’s Adaptive Pathways pilot program, which is part of the EMA’s effort to improve timely access for patients to new medicines.
The U.S. Food and Drug Administration (FDA) also granted LentiGlobin Orphan Drug status and Breakthrough Therapy designation for the treatment of TDT.

Forward-Looking Statements
This release contains
“forward-looking statements” within the meaning of the Private
Securities Litigation Reform Act of 1995, including statements regarding
the Company’s views with respect to the potential for its LentiGlobin
product candidate to treat transfusion-dependent ß-thalassemia, and the
Company’s expectations regarding the review, potential regulatory
approval and potential commercial launch of its LentiGlobin product
candidate in the United States and Europe. Any forward-looking
statements are based on management’s current expectations of future
events and are subject to a number of risks and uncertainties that could
cause actual results to differ materially and adversely from those set
forth in or implied by such forward-looking statements. These risks and
uncertainties include, but are not limited to, the risks that the
preliminary positive efficacy and safety results from our prior and
ongoing clinical trials of LentiGlobin will not continue or be repeated
in our ongoing or planned clinical trials of LentiGlobin, the risks that
the changes we have made in the LentiGlobin manufacturing will not
result in improved patient outcomes, risks that the current or planned
clinical trials of LentiGlobin will be insufficient to support future
regulatory submissions or to support marketing approval in the US and
EU, and the risk that any one or more of our product candidates, will
not be successfully developed, approved or commercialized. For a
discussion of other risks and uncertainties, and other important
factors, any of which could cause our actual results to differ from
those contained in the forward-looking statements, see the section
entitled “Risk Factors” in our most recent Form 10-Q, as well as
discussions of potential risks, uncertainties, and other important
factors in our subsequent filings with the Securities and Exchange
Commission. All information in this press release is as of the date of
