Generation Bio Reports Business Highlights and Second Quarter 2022 Financial Results

Cash balance of $312.2M expected to fund operations into 2025CAMBRIDGE, Mass., Aug. 04, 2022 (GLOBE NEWSWIRE) — Generation Bio Co. (Nasdaq: GBIO), a biotechnology company innovating genetic medicines for people living with rare and prevalent diseases, reported business highlights and second quarter 2022 financial results. “We are advancing our leading non-viral genetic medicine platform to unlock the potential of durable, redosable non-viral DNA therapeutics, and we have made significant progress in establishing the proprietary technologies necessary to realize our vision,” said Geoff McDonough, M.D., president and chief executive officer of Generation Bio. “This quarter, process development and scaling of rapid enzymatic synthesis (RES) for production of our closed-ended DNA (ceDNA) construct has allowed us to pursue a more flexible and capital efficient manufacturing strategy. In the remainder of the year, we plan to continue to develop our unique cell-targeted lipid nanoparticle (ctLNP) system for systemic delivery to hepatocytes, as well as for other therapeutic areas such as the retina and vaccines.” Business Highlights Announced update to Good Manufacturing Practice (GMP) manufacturing strategy: In June 2022, Generation Bio announced advances in process development for RES production of ceDNA that enabled a new modular and more flexible manufacturing approach. The productivity, high purity yield and short cycle time of RES at scale is expected to supply portfolio programs for the next 10 years and requires a much smaller manufacturing footprint than previously anticipated. The company is therefore seeking to assign its lease or sublease the manufacturing facility it had planned to build out and will execute an alternative GMP strategy that provides control over personnel, quality, infrastructure and process know-how while enhancing capital efficiency. As a result of the decision to assign or sublease the property, Generation Bio is able to reallocate financial resources from the buildout to extend its projected cash runway into 2025.Appointed Dannielle Appelhans to Board of Directors: In July 2022, the company announced the appointment of Dannielle Appelhans to its Board of Directors. Appelhans is an experienced pharmaceutical executive who has built deep expertise in strategy, manufacturing, supply chain and operations, and is currently the Chief Operating Officer of Rubius Therapeutics. Second Quarter 2022 Financial Results Cash Position: Cash, cash equivalents and marketable securities were $312.2 million as of June 30, 2022, compared with $375.1 million in cash and cash equivalents as of December 31, 2021. The company believes that its cash position will fund its operating plan into 2025.R&D Expenses: Research and development (R&D) expenses were $28.4 million for the quarter ended June 30, 2022, compared to $22.7 million for the quarter ended June 30, 2021.G&A Expenses: General and administrative (G&A) expenses were $10.1 million for the quarter ended June 30, 2022, compared to $8.2 million for the quarter ended June 30, 2021.Net Loss: Net loss was $37.9 million, or $0.66 basic and diluted net loss per share, for the quarter ended June 30, 2022, compared to a net loss of $30.8 million, or $0.55 basic and diluted net loss per share, for the quarter ended June 30, 2021. About Generation BioGeneration Bio is innovating genetic medicines to provide durable, redosable treatments for people living with rare and prevalent diseases. The company’s non-viral genetic medicine platform incorporates a novel DNA construct called closed-ended DNA, or ceDNA; a unique cell-targeted lipid nanoparticle delivery system, or ctLNP; and a highly scalable capsid-free manufacturing process that uses proprietary cell-free rapid enzymatic synthesis, or RES, to produce ceDNA. The platform is designed to enable multi-year durability from a single dose, to deliver large genetic payloads, including multiple genes, to specific cell types, and to allow titration and redosing to adjust or extend expression levels in each patient. RES has the potential to expand Generation Bio’s manufacturing scale to hundreds of millions of doses to support its mission to extend the reach of genetic medicine to more people, living with more diseases, around the world.
