Eastern District of New York

The bluebird bio, Inc. class action lawsuit charges bluebird and certain of its executives with violations of the Securities Exchange Act of 1934 and seeks to represent purchasers or acquirers of bluebird securities between May 11, 2020 and November 4, 2020, inclusive (the “Class Period”).  The bluebird class action lawsuit was commenced on February 12, 2021 in the Eastern District of New York and is captioned Leung v. bluebird bio, Inc., No. 21-cv-00777.

bluebird is a biotechnology company that engages in researching, developing, and commercializing transformative gene therapies for severe genetic diseases and cancer.  The Company’s gene therapy programs include, among others, LentiGlobin (bb1111) for the treatment of sickle cell disease (“SCD”).  In May 2020, in the midst of the COVID-19 pandemic, bluebird announced that bluebird expected to submit a U.S. Biologics Licensing Application (“BLA”) to the U.S. Food and Drug Administration (“FDA”) for LentiGlobin for SCD in the second half of 2021.

The bluebird class action lawsuit alleges that, throughout the Class Period, defendants made false and/or misleading statements and/or failed to disclose that: (i) data supporting bluebird’s BLA submission for LentiGlobin for SCD was insufficient to demonstrate drug product comparability; (ii) defendants downplayed the foreseeable impact of disruptions related to the COVID-19 pandemic on the Company’s BLA submission schedule for LentiGlobin for SCD, particularly with respect to manufacturing; (iii) as a result of all the foregoing, it was foreseeable that the Company would not submit the BLA for LentiGlobin for SCD in the second half of 2021; and (iv) as a result, the Company’s public statements were materially false and misleading at all relevant times.

On November 4, 2020, bluebird disclosed that it would no longer apply for FDA approval of its LentiGlobin product as a treatment for SCD in the second half of 2021 as expected.  Instead, citing “feedback” from the FDA requiring the Company to provide additional data “to demonstrate drug product comparability” for LentiGlobin for SCD, “alongside COVID-19 related shifts and contract manufacturing organization COVID-19 impacts,” bluebird adjusted its submission timing to late 2022.  On this news, bluebird’s stock price fell more than 16%, damaging invertors.

The Private Securities Litigation Reform Act of 1995 permits any investor who purchased bluebird securities during the Class Period to seek appointment as lead plaintiff in the bluebird class action lawsuit.  A lead plaintiff is generally the movant with the greatest financial interest in the relief sought by the putative class who is also typical and adequate of the putative class.  A lead plaintiff acts on behalf of all other class members in directing the bluebird class action lawsuit.  The lead plaintiff can select a law firm of its choice to litigate the bluebird class action lawsuit.  An investor’s ability to share in any potential future recovery of the bluebird class action lawsuit is not dependent upon serving as lead plaintiff.  If you wish to serve as lead plaintiff of the bluebird class action lawsuit or have questions concerning your rights regarding the bluebird class action lawsuit, please provide your information here or contact counsel, J.C.
