Generation Bio Reports Recent Business Highlights and Third Quarter 2024 Financial Results

• Non-human primate data presented at ESGCT demonstrated selective in vivo delivery of mRNA with T cell-targeted lipid nanoparticle (ctLNP)
  

• Cash balance of $199.8 million expected to fund operations into 2H 2027

CAMBRIDGE, Mass., Nov. 06, 2024 (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 third quarter 2024 financial results.

“There is immense potential for a new class of redosable, selectively targeted in vivo genetic medicines to fulfill the needs of people living with diseases that remain unaddressed by existing treatment options,” said Geoff McDonough, chief executive officer of Generation Bio. “Our cell-targeted lipid nanoparticle (ctLNP) platform has recently demonstrated highly selective in vivo delivery of mRNA to T cells in non-human primates (NHPs), a key milestone on the path to developing in vivo programs for T cell-mediated autoimmune diseases.”

Generation Bio recently presented data at the European Society of Gene and Cell Therapy (ESGCT) 31st Annual Congress from an NHP study showing that a single IV dose of a ctLNP delivering mRNA selectively to T cells transduced most circulating T cells with balanced distribution to CD4+ and CD8+ cells. These data confirm and improve on the potency and biodistribution profiles seen in previous murine and NHP studies, which have shown minimal off-target distribution to LNP clearance tissues. The NHP study was conducted as part of the company’s collaboration with Moderna, Inc.

Third Quarter 2024 Financial Results

• Cash Position: Cash, cash equivalents, and marketable securities were $199.8 million as of September 30, 2024, compared to $264.4 million in cash, cash equivalents, and marketable securities as of December 31, 2023.

• G&A Expenses: General and administrative (G&A) expenses were $9.2 million for the quarter ended September 30, 2024, compared to $11.6 million for the quarter ended September 30, 2023.

About Generation Bio
Generation Bio is innovating non-viral genetic medicines to provide durable and redosable treatments for hundreds of millions of patients living with rare and prevalent diseases. The company is developing two distinct and complementary platforms: a potent, highly selective cell-targeted lipid nanoparticle (ctLNP) delivery system and a novel immune-quiet DNA (iqDNA) cargo produced by a scalable capsid-free manufacturing process that uses proprietary cell-free rapid enzymatic synthesis (RES). With these platforms, Generation Bio aims to develop the next wave of non-viral genetic medicines to support its mission to extend the reach of genetic medicine to more people living with more diseases, around the world.
