The complaint filed alleges that throughout the class period, defendants made materially false and / or misleading statements and failed to advise investors that:

  • Data in support of Bluebird’s BLA filing for LentiGlobin for SCD were insufficient to demonstrate drug comparability;
  • Defendants have downplayed the foreseeable impact of disruptions related to the COVID-19 pandemic on the company’s BLA filing schedule for LentiGlobin for SCD, particularly with respect to manufacturing.
  • As a result of the foregoing, it was foreseeable that the company would not file the BLA for LentiGlobin for SCD in the second half of 2021. and
  • As a result, the company’s public statements have been materially false and misleading at all relevant times.

Company shares fell as much as 35% for the day on February 16, 2020 after the company announced the suspension of its Phase 1/2 and Phase 3 trials of its sickle cell therapy candidate.

The company has suspended the studies because of a reported suspected unexpected serious side effect (SUSAR) in acute myeloid leukemia (AML). Bluebird put the study on hold after receiving reports last week that a patient who was treated in a study more than five years ago was diagnosed with AML.
