"We ended 2016 with momentum to drive progress in 2017 and cash to fund the business well into 2019," said Nick Leschly, chief bluebird. "2017 is a critical year for bluebird, with data readouts across all four of our clinical programs, including proof-of-concept data on manufacturing improvements for LentiGlobin; proof-of-concept data for the changes to the HGB-206 study protocol; additional data from our anti-BCMA CAR T program, bb2121; and full data from the first 17 patients in the Starbeam study of Lenti-D. Execution will also be a key theme for 2017, with a focus on laying the groundwork for future MAA and BLA filings and engagement with payors. All of these activities are building to the 2022 vision we laid out in January: to have multiple products on the market with dramatic patient impact and a deep pipeline driven by a sustainable innovation engine."

Recent Highlights

FIRST CLINICAL DATA FOR ANTI-BCMA CAR T PROGRAM REPORTED – In November, bluebird bio announced interim phase 1 dose escalation data for its anti-BCMA CAR T product candidate in patients with relapsed/refractory multiple myeloma. 100% of patients in the second and third dose cohorts (n=6) achieved an objective response; two patients were MRD-negative. The overall response rate (ORR) was 78%. Two patients in the study achieved stringent complete responses, with 6 and 4 months follow-up. Among all dosed patients (n=11), no dose-limiting toxicities were observed as of the November data cut-off date, and no Grade 3 or Grade 4 cytokine release syndrome or Grade 3 or Grade 4 neurotoxicity were observed as of the data cut-off.
LENTIGLOBIN DATA AT ASH (Free ASH Whitepaper) – At the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting, bluebird provided updates across its ongoing studies of LentiGlobin in transfusion-dependent β-thalassemia (TDT) and severe sickle cell disease (SCD). Updated interim clinical data from the Northstar (HGB-204) study of LentiGlobin drug product in TDT confirmed that all patients with non-β0/β0 genotypes and ≥12 months of follow-up have stopped regular transfusions; patients with β0/β0 genotypes and ≥12 months of follow-up had a median reduction in transfusion volume of 63% as of the September 16, 2016 data cut-off. In the HGB-205 study, the first patient with SCD treated with gene therapy remains free of clinical symptoms 21 months after receiving LentiGlobin drug product, and ongoing transfusion independence and sustained production of HbAT87Q were reported in patients with TDT as of the September 9, 2016 data cut-off. Updated interim clinical data from seven subjects in the HGB-206 study of LentiGlobin drug product in SCD underscore the need for recently implemented protocol amendments seeking to improve HbAT87Q production in this population.
STUDIES OF LENTIGLOBIN DRUG PRODUCT MANUFACTURED WITH NEW PROCESS UNDERWAY – In December, the first patient was treated with LentiGlobin drug product in the Northstar-2 (HGB-207) phase 3 clinical study of patients with TDT and non-β0/β0 genotypes. A LentiGlobin drug product vector copy number (DP VCN) of 2.9 copies/diploid genome was observed, with 77% of cells lentiviral vector sequence positive (LVV+). In February of 2017, the first patient was treated under the amended study protocol for the HGB-206 phase 1 clinical study of patients with SCD. A LentiGlobin DP VCN of 3.3 copies/diploid genome was observed, with 83% of cells LVV+ for this patient.
MANUFACTURING AGREEMENT WITH APCETH – In December, bluebird and apceth Biopharma announced that they have entered into a strategic manufacturing agreement providing for the future European commercial production of bluebird bio’s Lenti-D product candidate for cerebral adrenoleukodystropy (CALD) and its LentiGlobin product candidate for TDT. This agreement follows a successful multi-year clinical manufacturing relationship and provides bluebird bio with European commercial manufacturing capabilities, including dedicated production suites within apceth Biopharma’s state-of-the-art GMP facility.
KEY MANAGEMENT APPOINTMENTS – Susanna High was named chief operating officer and Andrew Obenshain was named senior vice president and head of Europe.
FULLY ENROLLED HGB-205 STUDY – In February of 2017, the final patient with SCD in the HGB-205 single-center study in TDT and SCD was infused with LentiGlobin drug product.
REOPENED STARBEAM STUDY – In December, bluebird bio announced plans to expand enrollment by up to eight additional patients in the ongoing Starbeam Phase 2/3 clinical study of Lenti-D drug product in patients less than 18 years of age with cerebral adrenoleukodystrophy (CALD). The expansion of the study is intended to enable the first manufacture of Lenti-D in Europe and subsequent treatment of subjects in Europe, and to bolster the overall clinical data package for potential future regulatory filings in the United States and Europe.
STRENGTHENED BALANCE SHEET – In December, bluebird raised $234.7 million in net proceeds in an equity financing. The company’s cash, cash equivalents and marketable securities are sufficient to fund operations into the second half of 2019 based on the company’s current business plan. Proceeds from the equity financing will fund the advancement of bb2121 and other anti-BCMA product candidates for the treatment of relapsed/refractory multiple myeloma; the initiation of HGB-212, a phase 3 clinical study of LentiGlobin in patients with TDT and the β0/β0 genotype; the expansion of manufacturing capabilities to support product development efforts and in anticipation of a potential commercial launch; and the growth of commercial infrastructure to support conditional commercial launch of LentiGlobin in Europe pending marketing authorization in Europe.
Upcoming Anticipated Milestones:

Presentation of updated bb2121 clinical data from the CRB-401 study at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting
Presentation of early LentiGlobin clinical data from the HGB-207 study at the European Hematology Association (EHA) (Free EHA Whitepaper) Annual Meeting
Initiation of a phase 1 clinical study of bb21217 anti-BCMA CAR T product candidate
Initiation of HGB-212, phase 3 clinical study of LentiGlobin in patients with TDT and the β0/β0 genotype in the second half of 2017
Presentation of full data from the initial 17 patients treated in the Starbeam clinical study of Lenti-D in CALD by year end 2017
Presentation of early LentiGlobin clinical data from the HGB-206 study conducted under the amended study protocol at ASH (Free ASH Whitepaper)
Fourth Quarter and Full Year 2016 Financial Results and Financial Guidance

Cash Position: Cash, cash equivalents and marketable securities as of December 31, 2016 were $884.8 million, compared to $865.8 million as of December 31, 2015, an increase of $19.0 million, which was primarily driven by the December 2016 equity financing partially offset by cash used to fund operations.
Revenues: Collaboration revenue was $1.6 million for the fourth quarter of 2016 and $6.2 million for the year ended December 31, 2016, compared to $1.5 million and $14.1 million in the comparable periods in 2015. The decrease for the full year is a result of a change in revenue recognition associated with an amendment to our collaboration agreement with Celgene in the second quarter of 2015.
R&D Expenses: Research and development expenses were $57.1 million for the fourth quarter of 2016 and $204.8 million for the year ended December 31, 2016, compared to $35.7 million and $134.0 million in the comparable periods in 2015. The increase in research and development expenses was primarily attributable to increased manufacturing costs for our ongoing clinical and pre-clinical studies, increased employee compensation expense and increased information technology and facilities costs to support our overall growth.
G&A Expenses: General and administrative expenses were $16.2 million for the fourth quarter of 2016 and $65.1 million for the year ended December 31, 2016, compared to $14.4 million and $46.2 million in the comparable periods in 2015. The increase in general and administrative expenses was primarily attributable to increased employee compensation expense and consulting costs to support our overall growth and pre-commercial efforts.
Net Loss: Net loss was $71.4 million for the fourth quarter of 2016 and $263.5 million for the year ended December 31, 2016, compared to $47.3 million and $166.8 million in the comparable periods in 2015.
Financial guidance: bluebird bio expects that its cash, cash equivalents and marketable securities of $884.8 million as of December 31, 2016 will be sufficient to fund its current operations into the second half of 2019.
