bluebird bio Reports First Quarter Financial Results and Highlights Operational Progress

bluebird bio, Inc. (NASDAQ: BLUE) today reported financial results and business highlights for the first quarter ended March 31, 2021 and shared recent operational progress.

“Undoubtedly the highlight of last quarter at bluebird was the approval of Abecma, the first and only CAR T therapy approved for the treatment of relapsed or refractory multiple myeloma,” said Nick Leschly, chief bluebird. “We and our colleagues at BMS are now full speed ahead and on track to begin treating patients this quarter. It has been an amazing journey and in many ways, we’re just getting started. While the oncology team has been delivering on Abecma, the severe genetic disease team met the moment. We quickly completed an investigation of the SUSAR of AML in our HGB-206 study of LentiGlobin gene therapy for SCD and determined that it was highly unlikely to be due to BB305 lentiviral vector. With these data and the other event changed from an MDS diagnosis to transfusion-dependent anemia, we are now quickly moving to engage with regulators with a goal of lifting the clinical holds in mid-2021. Amidst these challenges and work towards the planned separation, I want to commend and thank all birds for truly demonstrating anti-fragility and continuing to keep patients at the center of everything we do.”

BUSINESS SEPARATION UPDATE

Today, bluebird bio is providing additional detail regarding the company’s planned business separation, which is targeted for completion by year-end 2021.

RECENT HIGHLIGHTS

MULTIPLE MYELOMA

• ABECMA FDA APPROVAL – On March 26, 2021, bluebird bio and Bristol-Myers Squibb announced that the U.S. Food and Drug Administration (FDA) approved Abecma (idecabtagene vicleucel; ide-cel) as the first B-cell maturation antigen (BCMA)-directed chimeric antigen receptor (CAR) T cell immunotherapy for the treatment of adult patients with relapsed or refractory multiple myeloma (RRMM) after four or more prior lines of therapy, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 monoclonal antibody. Abecma is a personalized immune cell therapy approved as a one-time infusion with a recommended dose range of 300 to 460 x 10⁶ CAR-positive T cells.

• KARMMA NEJM PUBLICATION– On February 24, 2021, bluebird bio and Bristol-Myers Squibb announced that results from the pivotal Phase 2 KarMMa study were published in The New England Journal of Medicine. The KarMMa study met its primary endpoint of overall response rate and key secondary endpoint of complete response rate. The data from the study demonstrates deep and durable responses with ide-cel treatment in triple-class exposed RRMM patients (n=128).

SICKLE CELL DISEASE

• CLINICAL STUDIES UPDATE – On April 20, 2021, bluebird bio announced 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). Upon further assessment, the treating investigator concluded this is not a case of MDS and revised the diagnosis to transfusion-dependent anemia. In addition, on March 10, 2021, bluebird bio 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). 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.

CEREBRAL ADRENOLEUKODYSTROPHY

• ELI-CEL DATA AT EBMT– On March 15, 2021, bluebird bio presented new data suggesting durability of response and a strong safety profile post elivaldogene autotemcel (eli-cel, Lenti-D™) gene therapy in patients with cerebral adrenoleukodystrophy (CALD) at the 47th Annual Meeting of the European Society for Blood and Marrow Transplantation (EBMT 2021). Long-term results from the Phase 2/3 Starbeam study of eli-cel, showed that ninety percent of patients (27/30) are alive and free of major functional disabilities (MFDs) at 24 months or more of follow-up. In the 51 patients treated with eli-cel in clinical studies (ALD-102/LTF-304 and ALD-104) there were no reports of graft failure, graft rejection, GVHD, replication competent lentivirus or insertional oncogenesis.

PIPELINE

• BILL & MELINDA GATES FOUNDATION GRANT TO EXPLORE IN-VIVO LVV APPLICATIONS - bluebird bio is announcing today that it has received a grant from the Bill & Melinda Gates Foundation to explore new, potentially transformative in vivo treatments for SCD using the Company’s proprietary lentiviral vector (LVV) platform. The funding will support the research and development of novel LVVs that target hematopoietic stem cells (HSCs) for in vivo administration to bring gene-based therapies for SCD and other potential indications to patients around the world who may have limited access to ex vivo and other emerging therapies. This research may also enable the application of in-vivo LVV approaches in other severe genetic diseases.

• PSIOXUS PRE-CLINICAL DATA - On April 14, 2021, bluebird bio and PsiOxus Therapeutics presented preclinical data at the American Association for Cancer Research (AACR) Annual Meeting 2021. The results showed synergistic activity between PsiOxus’ T-SIGn vector and bluebird bio’s CAR-T therapy in primary and metastatic solid tumors. A single IV cycle of PsiOxus’ T-SIGn vector enabled an otherwise non-effective dose of CAR-T cell therapy to clear primary and metastatic tumors in vivo.

COMPANY

• BUSINESS OPERATIONS – On April 20, 2021 bluebird bio announced its decision to withdraw ZYNTEGLO™ (betibeglogene autotemcel, beti-cel) for transfusion-dependent β-thalassemia (TDT) from the German market because 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. Due in part to this decision, the company also announced a targeted reshaping of its workforce intended to enable the company to advance its late-stage gene therapy programs. 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.

UPCOMING ANTICIPATED MILESTONES

Regulatory Outlook

• SCD: The company is investigating the recently-reported safety events and plans to continue to work closely with the FDA in their review of these events to provide an update on the Company’s development plan and timeline for submission for regulatory approval by year end.
• TDT: The company is on track to complete its rolling BLA submission to the U.S. FDA for beti-cel in mid-2021, contingent upon successful resolution of any U.S. FDA concerns applicable to the program arising out of the recently-reported safety events in the SCD program. This submission is anticipated to include adult, adolescent and pediatric patients with transfusion dependent β-thalassemia across all genotypes (including non-β0/β0 genotypes and β0/β0 genotypes).
• CALD: The company is on track to complete its BLA submission to the U.S. FDA for eli-cel in mid-2021. The company plans to receive European approval for eli-cel in patients with CALD in mid-2021.

Clinical Updates and Milestones

• Updated data from ongoing clinical study in patients with SCD by the end of 2021.
• Updated data from ongoing clinical studies in patients with TDT in mid-2021.
• Updated clinical data from the ongoing pivotal Phase 2 KarMMa study of Abecma (ide-cel, bb2121) in patients with relapsed and refractory multiple myeloma to be presented at the American Society of Clinical Oncology 2021 (ASCO21) Virtual Scientific Program on June 4.
• bb21217 clinical data from the ongoing CRB-402 study in patients with multiple myeloma by the end of 2021.
• Submission of 1 - 2 investigational new drug (IND) applications by the end of 2021.

FIRST QUARTER 2021 FINANCIAL RESULTS

• Cash Position: Cash, cash equivalents and marketable securities as of March 31, 2021 and December 31, 2020 were $1.09 billion and $1.27 billion, respectively. The decrease in cash, cash equivalents and marketable securities is primarily related to cash used in support of ordinary course operating activities.
• Revenues: Total revenues were $12.8 million for the three months ended March 31, 2021 compared to $21.9 million for the three months ended March 31, 2020. The decrease was primarily driven by a decrease in ide-cel license and manufacturing services revenue and a decrease in revenue recognized in connection with treating patients in the Phase 1 CRB-402 study of bb21217 under our agreements with BMS.
• R&D Expenses: Research and development expenses were $154.5 million for the three months ended March 31, 2021 compared to $154.1 million for the three months ended March 31, 2020. The increase was primarily driven by increased costs incurred through the amended BMS collaboration as well as an increase in employee compensation, benefit, and other headcount related expenses. These increased costs were partially offset by a decrease in manufacturing costs.
• SG&A Expenses: Selling, general and administrative expenses were $86.9 million for the three months ended March 31, 2021 compared to $73.2 million for the three months ended March 31, 2020. The increase was primarily driven by increased employee compensation, benefit, and other headcount related expenses, as well as an increase in consulting fees associated with the ongoing project to separate the Company’s severe genetic disease and oncology programs into two independently traded companies. These increased costs were partially offset by a decrease in costs related to commercial readiness activities due to delays in commercialization as a result of the COVID-19 pandemic and in light of safety events in the HGB-206 study of LentiGlobin gene therapy for SCD.
• Net Loss: Net loss was $205.8 million for the three months ended March 31, 2021 compared to $202.6 million for the three months ended March 31, 2020.
