bluebird bio Stock: Berger Montague Investigates Alleged Securities Fraud Claims Against bluebird bio, Inc. (BLUE); Lead Plaintiff Deadline is April 13, 2021

Philadelphia, Pennsylvania--(Newsfile Corp. - March 5, 2021) -  Berger Montague is investigating potential securities fraud claims against bluebird bio, Inc. ("bluebird" or the "Company") on behalf of investors who purchased bluebird securities (NASDAQ: BLUE) between May 11, 2020 and November 4, 2020 (the "Class Period").

If you purchased bluebird securities during the Class Period, have questions concerning your rights or interests, or would like to discuss Berger Montague's investigation, please contact attorneys Andrew Abramowitz at or (215) 875-3015, or Donnell Much at or (215) 875-4667, or contact us at:

According to a recently filed lawsuit, defendants misled investors during the Class Period by, among other things: (i) failing to disclose that the data supporting bluebird's Biologics License Application ("BLA") submission for LentiGlobin, a gene therapy intended to treat sickle cell disease, was insufficient to demonstrate drug product comparability; (ii) downplaying the potential impact of COVID-related disruptions on the Company's BLA submission schedule; and (iii) failing to inform the market that it was foreseeable that bluebird would not submit the BLA for LentiGlobin in the second half of 2021.

The lawsuit alleges that investors learned the truth on November 4, 2020, when bluebird disclosed that it would no longer submit its BLA for LentiGlobin in the second half of 2021. Instead, citing "feedback" from the FDA requiring the Company to provide additional data demonstrating "drug product comparability," as well as COVID-related "shifts and contract manufacturing" impacts, bluebird adjusted its submission timing to late 2022.

On this news, bluebird's stock price fell $9.72 per share, or 16.6%, to close at $48.83 per share on November 5, 2020.

If you purchased bluebird securities during the Class Period, you may seek Court appointment as lead plaintiff to represent other injured investors in a class action. The lead plaintiff appointment deadline is April 13, 2021. You do not need to be a lead plaintiff to share in any potential Class recovery.
