CASE ALLEGATIONS: bluebird bio is a biotechnology company that researches, develops, and commercializes gene therapies for severe genetic diseases. According to the complaint, on April 24, 2023, defendants announced submission of its Biologics License Application (BLA) to the U.S. Food and Drug Administration (“FDA”) for lovotibeglogene autotemcel (“lovo-cel”) gene therapy in patients with sickle cell disease (SCD) ages 12 and older who have a history of vaso-occlusive events.

The bluebird bio class action lawsuit alleges that defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (i) bluebird bio could not obtain FDA approval for lovo-cel without any black box warnings for haematological malignancies; (ii) bluebird bio would not be granted a priority review voucher by the FDA and in turn sell it to strengthen bluebird bio’s financial position for the lovo-cel launch; and (iii) as a result, bluebird bio had significantly overstated Lyfgenia’s clinical and/or commercial prospects.

The bluebird bio class action lawsuit further alleges that on December 8, 2023, bluebird bio disclosed that: (i) it received approval from the FDA for its ex-vivo gene therapy drug Lyfgenia for sickle cell disease; (ii) along with the approval came a black box warning for haematological malignancies with a requirement to monitor patients for cancer through complete blood counts at least every 6 months for at least 15 years, plus viral vector integration site analysis at month 6, 12, and as warranted; and (iii) bluebird bio’s anticipated priority review voucher was denied by the FDA. On this news, the price of bluebird bio stock fell more than 40%, according to the complaint.
