bluebird bio, Inc. (NASDAQ: BLUE) today reported financial results and business highlights for the second quarter ended June 30, 2018.

“The clinical data presented this spring across our development programs in TDT, SCD and multiple myeloma have further reinforced the strength of our gene and cell therapy platforms, and we are putting tremendous effort towards bringing all four of our clinical programs to patients as soon as possible,” said Nick Leschly, chief bluebird. “In the second half of the year, we anticipate reaching a significant milestone for bluebird, by filing for our first potential regulatory approval in Europe with LentiGlobin to treat TDT. As we prepare to make this important transition to a commercial company, with the potential for three initial product approvals by the end of 2020, our readiness and implementation plans are well underway. We are also investing and building for our next phase of growth through a sustainable innovation engine, and a strong development and commercial infrastructure to allow us to bring more transformative therapies to patients.”

Recent Highlights

TDT

• LENTIGLOBIN ACCELERATED ASSESSMENT – In July 2018, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) granted an accelerated assessment to LentiGlobin in transfusion-dependent β-thalassemia (TDT). The company is on track to submit a Marketing Authorization Application (MAA) to the EMA for LentiGlobin in 2018.
• NEW DATA FROM NORTHSTAR AND NORTHSTAR-2 PRESENTED – At the Annual Congress of the European Hematology Association (EHA) in June 2018, bluebird bio presented new data from its studies of LentiGlobin in patients with TDT: Northstar (HGB-204) and Northstar-2 (HGB-207). As of the data cutoff, 7/8 non-β⁰/β⁰ patients with ≥ 6 months follow-up were producing normal or near-normal amounts of total hemoglobin (11.1 – 13.3 g/dL) and were transfusion free in Northstar-2. 8/10 of non-β⁰/β⁰ patients achieved and maintained transfusion independence for up to 3 years in Northstar. Across both studies, the safety profile was consistent with myeloablative conditioning.
• FIRST PEDIATRIC PATIENT TREATED – In April 2018, the first pediatric patient was treated in Northstar-3 (HGB-212), bluebird bio’s Phase 3 study of LentiGlobin in patients with β⁰/β⁰ genotypes.

SCD

• NEW DATA FROM HGB-206 PRESENTED – At EHA in June 2018, bluebird bio presented new data from the HGB-206 study of LentiGlobin in patients with severe sickle cell disease (SCD). As of the data cutoff, all patients (n=4) in Group C with ≥ 3 months follow-up were consistently producing ≥ 30% anti-sickling HbA^T87Q. The first Group C patient was generating a normal total hemoglobin of 14.2 g/dL with over 60% anti-sickling HbA^T87Q at 6 months. Across all patients in the study, the safety profile was consistent with myeloablative conditioning.

MULTIPLE MYELOMA

• NEW DATA FROM CRB-401 PRESENTED – At the American Society of Clinical Oncology (ASCO) Annual Meeting in June 2018, bluebird bio and Celgene Corporation presented new data from the ongoing CRB-401 Phase 1 clinical study of bb2121, an investigational anti-B-cell maturation antigen (BCMA) CAR T cell therapy, in 43 patients with late-stage relapsed/refractory multiple myeloma. Deep and durable responses were observed at active doses (≥150 × 10⁶ CAR+ T cells). A median progression-free survival (PFS) of approximately one year was achieved in heavily pre-treated patients in the active doses of the dose escalation cohort. Consistent response rates were observed for both low and high BCMA expression levels. Adverse events have been manageable across doses.

CALD

• PRIME DESIGNATION FOR LENTI-D – In July 2018, the EMA granted access to its Priority Medicines (PRIME) scheme for Lenti-D for the treatment of patients with cerebral adrenoleukodystrophy (CALD). The PRIME initiative provides enhanced support and increased interaction to companies, with the goal of optimizing development plans and speeding regulatory evaluations to potentially bring innovative medicines to patients more quickly. To be accepted for PRIME, a therapy must demonstrate potential to benefit patients with unmet medical need through early clinical data or nonclinical data.
• BREAKTHROUGH DESIGNATION FOR LENTI-D – In May 2018, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy designation to Lenti-D for the treatment of patients with CALD. Lenti-D previously was granted Orphan Drug designation by the FDA and EMA, as well as Rare Pediatric Disease designation by the FDA.

COMPANY

• STRENGTHENED BALANCE SHEET – In July 2018, bluebird bio raised approximately $600.6 million in net proceeds through a public equity offering. bluebird bio anticipates that its cash, cash equivalents and marketable securities will be sufficient to fund operations into 2022 based on the company’s current business plan.

Second Quarter 2018 Financial Results

• Cash Position: Cash, cash equivalents and marketable securities as of June 30, 2018 and December 31, 2017 were $1.46 billion and $1.61 billion, respectively.
• Revenues: Total revenues were $7.9 million for the three months ended June 30, 2018 compared to $16.7 million for the three months ended June 30, 2017. The decrease of approximately $8.9 million was primarily attributable to license revenue recognized in the second quarter of 2017 as a result of out-licensing arrangements entered into during that quarter. Total revenues were $23.8 million for six months ended June 30, 2018 compared to $23.5 million for six months ended June 30, 2017. The increase of $0.3 million was primarily attributable to an overall increase in collaboration revenue for the bb2121 license and manufacturing services under the company’s agreement with Celgene, offset by a decrease in license and royalty revenue.
• R&D Expenses: Research and development expenses were $115.0 million for the three months ended June 30, 2018 compared to $63.9 million for the three months ended June 30, 2017. Research and development expenses were $212.1 million for six months ended June 30, 2018 compared to $118.9 million for six months ended June 30, 2017. The increase in both periods was driven by costs incurred to advance and expand the company’s pipeline and is attributable to increased clinical trial-related costs and manufacturing costs for development programs, increased laboratory expenses, increased employee-related costs due to headcount growth, and increased license milestones and fees under the company’s strategic collaboration and license agreements.
• G&A Expenses: General and administrative expenses were $41.2 million for the three months ended June 30, 2018 compared to $21.2 million for the three months ended June 30, 2017. General and administrative expenses were $76.1 million for six months ended June 30, 2018 compared to $41.5 million for six months ended June 30, 2017. The increase in both periods was attributable to increases in employee-related costs due to increased headcount to support overall growth, commercial-readiness activities, and professional and consulting fees.
• Net Loss: Net loss was $146.0 million for the three months ended June 30, 2018 compared to $70.9 million for the three months ended June 30, 2017. Net loss was $261.1 million for six months ended June 30, 2018 compared to $139.6 million for six months ended June 30, 2017.
