On December 19, 2022, bluebird bio, Inc. (the “Company”) announced that the U.S. Food and Drug Administration lifted its partial clinical hold for patients under the age of 18 in studies evaluating lovotibeglogene autotemcel (lovo-cel) for sickle cell disease.
In December 2021, lovo-cel clinical studies were placed on a partial hold for patients under the age of 18. The hold related to an investigation by the Company into an adolescent patient with persistent, non-transfusion-dependent anemia following treatment with lovo-cel. Based on an investigation of the case and an investigation of an adult patient with persistent anemia following treatment with lovo-cel, patients with a specific genotype known as an alpha-thalassemia trait were added to the exclusion criteria for ongoing studies.
Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
