“Transfusion-dependent β-thalassemia is a severe genetic disease that
requires a lifetime of chronic blood transfusions for survival, and
while these transfusions are life-saving, they are also associated with
serious medical complications such as organ failure from iron overload,”
said
bluebird bio intends to file an MAA for LentiGlobin in TDT with the EMA in 2018. Accelerated assessments can reduce the active review time of an MAA from 210 days to 150 days once it has been validated by the EMA. An accelerated assessment is granted to products deemed by the CHMP to be of major interest for public health and represent therapeutic innovation.
The accelerated assessment for LentiGlobin is supported by data from clinical studies, including the completed Phase 1/2 Northstar (HGB-204) study, 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.
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.

About Transfusion-Dependent β-Thalassemia
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. TDT is the most severe clinical presentation of β-thalassemia and includes patients who receive blood transfusions as frequently as every two to four weeks.
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 (HSCT) is currently the only available option with the potential to correct the genetic deficiency in TDT. Complications of allogeneic 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 allogeneic HSCT.

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 development and regulatory approval plans for its
LentiGlobin product candidate to treat transfusion-dependent
ß-thalassemia. 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 regulatory submissions or 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
