FDA Lifts Partial Hold on Bluebird Bio Lovo-Cel Study

Share

FDA has lifted its partial clinical hold for patients under age 18 in studies evaluating Bluebird Bio’s lovotibeglogene autotemcel (lovo-cel) for sickle cell disease. A company statement says the agency placed the studies on a partial hold for patients under age 18 in 12/2021 relating to a company investigation into an adolescent patient with persistent, non-transfusion-dependent anemia following treatment with lovo-cel.

Bluebird says its study of two patients with persistent anemia determined that they had two a-globin gene deletions, known as alpha-thalassemia trait, and the genotype was added to exclusion criteria for ongoing studies.

The company says it is working to resume enrollment and treatment of patients aged 2-17 consistent with the study protocol and remains on track to submit a BLA in the first quarter of this year.

FDA has granted orphan drug, fast track, regenerative medicine advanced therapy, and rare pediatric disease designations for lovo-cel, Bluebird says.

Lovo-cel gene therapy is described as an investigational one-time treatment being studied for sickle cell disease that is designed to add functional copies of a modified form of the β-globin gene into a patient’s hematopoietic stem cells.
