CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sep. 13, 2017--
bio, Inc. (NASDAQ: BLUE), a clinical-stage company committed to
developing potentially transformative gene therapies for serious genetic
diseases and T cell-based immunotherapies for cancer, today announced
that the expansion cohort of the CRB-401 Phase 1 study of bb2121, an
anti-BCMA CAR T therapy, has been initiated. The objective of the
CRB-401 study is to evaluate the safety and efficacy of bb2121 in
patients with relapsed/refractory multiple myeloma and determine a
recommended Phase 2 dose. bluebird bio and Celgene Corp. are jointly
“The high response rate and sustained benefit seen with bb2121 in the
recent data presented at the ASCO annual meeting in June are
particularly gratifying given the limited therapeutic options available
for the heavily pretreated patients with relapsed/refractory multiple
myeloma participating in our study,” said David Davidson, MD, chief
medical officer, bluebird bio. “In the expansion stage of the CRB-401
study, we will be treating an additional cohort of patients with a dose
range shown to be active in the prior dose escalation stage of the study
to gain more experience with the safety, efficacy and durability of
response of bb2121.”
Patients in the expansion cohort will be treated at a dose range of 150
to 450 x 106 CAR+ T cells and will be required to have
prior exposure to a proteasome inhibitor, an immunomodulatory agent and
About bluebird bio, Inc.
With its lentiviral-based gene
therapies, T cell immunotherapy expertise and gene editing capabilities,
bluebird bio has built an integrated product platform with broad
potential application to severe genetic diseases and cancer. bluebird
bio’s gene therapy clinical programs include its Lenti-D™ product
candidate, currently in a Phase 2/3 study, called the Starbeam Study,
for the treatment of cerebral adrenoleukodystrophy, and its LentiGlobin™
product candidate, currently in four clinical studies for the treatment
of transfusion-dependent β-thalassemia, and severe sickle cell disease.
bluebird bio’s oncology pipeline is built upon the company’s leadership
in lentiviral gene delivery and T cell engineering, with a focus on
developing novel T cell-based immunotherapies, including chimeric
antigen receptor (CAR T) and T cell receptor (TCR) therapies. bluebird
bio’s lead oncology program, bb2121, is an anti-BCMA CAR T program
partnered with Celgene. bb2121 is currently being studied in a Phase 1
trial for the treatment of relapsed/refractory multiple myeloma.
bluebird bio also has discovery research programs utilizing
megaTAL/homing endonuclease gene editing technologies with the potential
for use across the company’s pipeline.
bluebird bio has operations in Cambridge, Massachusetts, Seattle,
Washington and Europe.
About the bluebird bio-Celgene Collaboration
In March 2013,
bluebird bio and Celgene entered into a collaboration to develop
chimeric antigen receptor (CAR) T cell therapies to target and destroy
cancer cells. In June 2015, the collaboration was amended and restated
to focus on developing product candidates targeting B-cell maturation
antigen (BCMA). bluebird bio and Celgene are working together on the
initial, lead anti-BCMA product candidate (bb2121), and are developing
next-generation anti-BCMA product candidates, including bb21217.
This press release contains
forward-looking statements, which are generally statements that are not
historical facts, including statements regarding the potential of the
bb2121 product candidate to treat relapsed/refractory multiple myeloma
and future clinical development plans of the Company and Celgene.
Forward-looking statements can be identified by the words "expects,"
"anticipates," "believes," "intends," "estimates," "plans," "will,"
“outlook” and similar expressions. Forward-looking statements are based
on management’s current plans, estimates, assumptions and projections,
and speak only as of the date they are made. Neither Celgene nor
bluebird bio undertake any obligation to update any forward-looking
statement in light of new information or future events, except as
otherwise required by law. Forward-looking statements involve inherent
risks and uncertainties, most of which are difficult to predict and are
generally beyond each company’s control. These risks and uncertainties
include, but are not limited to, the risk that the bb2121 product
candidate will not be successfully developed, approved or commercialized
in relapsed/refractory multiple myeloma, or the risk that the bb2121
product candidate will be safe and efficacious in other disease
settings. Actual results or outcomes may differ materially from those
implied by the forward-looking statements as a result of the impact of a
number of factors, many of which are discussed in more detail in the
section entitled “Risk Factors”of the Annual Report on Form 10-K
and other reports of each company filed with the Securities and Exchange
