bluebird bio Provides Update on Severe Genetic Disease Programs and Business Operations
CAMBRIDGE, Mass. – (BUSINESS WIRE) – April 20, 2021 – bluebird bio, Inc. (Nasdaq: BLUE) announced today business and program updates across its severe genetic disease portfolio including a revised diagnosis for the previously reported case of myelodysplastic syndrome (MDS) in its Phase 1/2 study of LentiGlobin for sickle cell disease (SCD) (bb1111), the company’s decision to withdraw ZYNTEGLO™ (betibeglogene autotemcel, beti-cel) for transfusion-dependent β-thalassemia (TDT) from the German market and a targeted reshaping of its workforce intended to enable the company to advance its late-stage gene therapy programs.
The case of MDS reported in February in a patient from Group C of the Phase 1/2 HGB-206 study of LentiGlobin gene therapy for SCD has been further assessed following the review of results from additional tests. The treating investigator has concluded this is not a case of MDS and has revised the diagnosis to transfusion-dependent anemia. bluebird bio has reported this update to regulatory agencies and study investigators. The company continues to work with the treating investigator to determine the potential cause of this patient’s anemia.
Last month, the company reported that it is very unlikely the suspected unexpected serious adverse reaction (SUSAR) of acute myeloid leukemia (AML) reported in the HGB-206 study of LentiGlobin for SCD was related to the BB305 lentiviral vector (LVV). This assessment, along with the re-classification of the originally reported MDS case to transfusion-dependent anemia are important steps in bluebird bio’s path to seeking removal of the clinical hold on studies HGB-206 and HGB-210 of LentiGlobin for SCD. bluebird bio continues to work with regulators to resume its clinical studies in sickle cell disease as well as to remove the clinical hold for HGB-207 and HGB-212 clinical studies of beti-cel for β-thalassemia, with potential lift of all clinical holds in mid-2021.
In Europe, reimbursement negotiations in Germany did not result in a price for ZYNTEGLO that reflects the value of this one-time gene therapy with potential life-long benefit for people living with TDT. The price proposed by the German health authorities fails to recognize the severe burden of living with TDT or the innovation and benefit ZYNTEGLO brings to patients who are impacted every day, throughout their lives by this severe genetic disease.
bluebird bio continues with productive negotiations across countries in Europe and we plan to continue to provide updates on the negotiation processes in the second half of 2021.
In response to these and other events and shifts related to the business over the past year, bluebird bio plans to reduce and reshape its workforce, primarily in Europe. This reduction and reallocation of resources will allow the company to focus on priority European markets and streamline global operations going forward to ensure its ability to deliver gene therapies to patients based on bluebird bio’s current business plans.
“We remain committed to our pioneering mission to deliver one-time gene therapies with life-long benefits to our patients. We are grateful for the clinical investigators and healthcare providers helping us better understand the recent safety events in our sickle cell disease studies. We are confident that working with the FDA and EMA, we will be able to determine a positive path forward as we seek to re-open our clinical studies Further, through our continued engagement across Europe, we are optimistic that countries will reach pricing decisions that recognize the value of one-time gene therapies and provide the necessary access to the people who need them,” said Andrew Obenshain, president, severe genetic diseases, bluebird bio. “In terms of operations, we have faced challenges over the last year that
have resulted in the difficult decision to reduce our workforce and say goodbye to some valued bluebirds. We want to express our gratitude for their contributions and commitment to patients. As we move into the future, we look forward to bluebird bio advancing as a strong, thriving organization that is dedicated to developing treatments for rare genetic diseases.”
About HGB-206 and HGB-210
HGB-206 is a Phase 1/2 open-label study designed to evaluate the efficacy and safety of LentiGlobin gene therapy for sickle cell disease (SCD) that includes three treatment cohorts: Groups A, B and C. A refined manufacturing process designed to increase vector copy number (VCN) and further protocol refinements made to improve engraftment potential of gene-modified stem cells were used for Group C. Group C patients also received LentiGlobin for SCD made from HSCs collected from peripheral blood after mobilization with plerixafor, rather than via bone marrow harvest, which was used in Groups A and B of HGB-206.
HGB-210 is a Phase 3 single-arm open-label study designed to evaluate the efficacy and safety of LentiGlobin gene therapy for SCD in patients between two years and 50 years of age with sickle cell disease.
About LentiGlobin for SCD (bb1111)
LentiGlobin gene therapy for sickle cell disease (bb1111) is an investigational treatment being studied as a potential treatment for SCD. bluebird bio’s clinical development program for LentiGlobin for SCD includes the completed Phase 1/2 HGB-205 study, the Phase 1/2 HGB-206 study, and the Phase 3 HGB-210 study.
The U.S. Food and Drug Administration (FDA) granted orphan drug designation, fast track designation, regenerative medicine advanced therapy (RMAT) designation and rare pediatric disease designation for LentiGlobin for SCD.
LentiGlobin for SCD received orphan medicinal product designation from the European Commission for the treatment of SCD, and Priority Medicines (PRIME) eligibility by the European Medicines Agency (EMA) in September 2020.
bluebird bio is conducting a long-term safety and efficacy follow-up study (LTF-307) for people who have participated in bluebird bio-sponsored clinical studies of LentiGlobin for SCD. For more information visit: https://www.bluebirdbio.com/our-science/clinical-trials or clinicaltrials.gov and use identifier NCT04628585 for LTF-307.
LentiGlobin for SCD is investigational and has not been approved in any geography.
About Zynteglo (betibeglogene autotemcel)
Betibeglogene autotemcel (beti-cel) is a one-time gene therapy that adds functional copies of a modified form of the β-globin gene (βA-T87Q-globin gene) into a patient’s own hematopoietic (blood) stem cells (HSCs). Once a patient has the βA-T87Q-globin gene, they have the potential to produce HbAT87Q, which is gene therapy-derived adult Hb, at levels that may eliminate or significantly reduce the need for transfusions. In studies of beti-cel, transfusion independence (TI) is defined as no longer needing red blood cell transfusions for at least 12 months while maintaining a weighted average Hb of at least 9 g/dL.
The European Commission granted conditional marketing authorization (CMA) for beti-cel, marketed as ZYNTEGLO™ gene therapy, for patients 12 years and older with transfusion-dependent β-thalassemia (TDT) who do not have a β0/β0 genotype, for whom hematopoietic stem cell (HSC) transplantation is appropriate, but a human leukocyte antigen (HLA)-matched related HSC donor is not available.
Non-serious adverse events (AEs) observed during clinical studies that were attributed to beti-cel included abdominal pain, thrombocytopenia, leukopenia, neutropenia, hot flush, dyspnea, pain in extremity, tachycardia and non-cardiac chest pain. One serious adverse event (SAE) of thrombocytopenia was considered possibly related to beti-cel.
Additional AEs observed in clinical studies were consistent with the known side effects of HSC collection and bone marrow ablation with busulfan, including SAEs of veno-occlusive disease.
For details, please see the Summary of Product Characteristics (SmPC).
On April 28, 2020, the European Medicines Agency (EMA) renewed the CMA for beti-cel. The CMA for beti-cel is valid in the 27 member states of the EU as well as the UK, Iceland, Liechtenstein and Norway.
The U.S. Food and Drug Administration (FDA) granted beti-cel Orphan Drug status and Breakthrough Therapy designation for the treatment of TDT. Beti-cel is not approved in the U.S. Beti-cel continues to be evaluated in the ongoing Phase 3 Northstar-2 (HGB-207) and Northstar-3 (HGB-212) studies.
bluebird bio is conducting a long-term safety and efficacy follow-up study, LTF-303 for people who have participated in bluebird bio-sponsored clinical studies of ZYNTEGLO.
