CAMBRIDGE, Mass., May 10, 2023 (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 first quarter 2023 financial results.

“This year, we are focused on demonstrating proof-of-concept in non-human primates for hemophilia A, our lead program, which is the first step towards building a deep pipeline of rare and prevalent liver disease programs,” said Geoff McDonough, M.D., chief executive officer of Generation Bio. “We believe our partnership with Moderna will expand the development of our liver portfolio beyond hemophilia A, and that our collaboration to develop novel targeting of our stealth lipid nanoparticle to address immune cells will accelerate our ambition to reach new therapeutic areas beyond the liver.”

Business Highlights:

• Announced Strategic Collaboration with Moderna: In March 2023, Generation Bio announced a collaboration with Moderna that is intended to leverage the company’s cell-targeted lipid nanoparticles (ctLNP) and closed-ended DNA (ceDNA) technologies to create genetic medicines for the treatment of liver and non-liver diseases. Moderna acquired the option to advance two liver programs, each using a ctLNP to deliver ceDNA. In addition, the two companies have agreed to jointly develop novel targeting for Generation Bio’s stealth LNP to reach immune cells. Moderna has acquired the option to advance two immune cell programs, each using the collaboration ctLNP to deliver ceDNA. Moderna retains an additional option to license a third program either for the liver or for immune cells.

  Generation Bio received an upfront payment of $83.5 million, including $40 million in cash, $36 million in equity, and a $7.5 million research prepayment, and is eligible to receive up to $1.8 billion in milestone payments. Moderna will fund all research and development activities under the collaboration.

• Appointed Yalonda Howze, J.D. as Chief Legal Officer: In April 2023, the company announced the appointment of Yalonda Howze as Chief Legal Officer. Howze brings nearly two decades of experience in strategy and operations across legal, corporate governance and compliance for life science companies. She earned her J.D. from the University of Virginia School of Law, M. Div. from Harvard University School of Divinity, and B.A. from the University of Michigan.

First Quarter 2023 Financial Results

• Cash Position: Cash, cash equivalents, and marketable securities were $288.6 million as of March 31, 2023, not including an additional $47.5 million received in April 2023 from the collaboration with Moderna, compared to $279.1 million in cash, cash equivalents, and marketable securities as of December 31, 2022. The company continues to believe that its cash position will fund its operating plan into 2025.
• R&D Expenses: Research and development (R&D) expenses were $22.0 million for the quarter ended March 31, 2023, compared to $25.6 million for the quarter ended March 31, 2022.
• G&A Expenses: General and administrative (G&A) expenses were $12.9 million for the quarter ended March 31, 2023, compared to $9.8 million for the quarter ended March 31, 2022.
• Net Loss: Net loss was $32.1 million, or $0.53 basic and diluted net loss per share, for the quarter ended March 31, 2023, compared to a net loss of $35.0 million, or $0.61 basic and diluted net loss per share, for the quarter ended March 31, 2022.

About Generation Bio

Generation 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 tissues and 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.
