GBIO Generation Bio Company

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 2024 financial results.

“We continue to apply our proprietary cell-targeted LNP delivery system to develop in vivo genetic medicines for T cells, hematopoietic stem cells and hepatocytes,” said Geoff McDonough, chief executive officer of Generation Bio. “We believe our delivery platform has the potential to create uniquely differentiated in vivo therapeutics that are redosable, delivered at point-of-care, and scalable at low cost, thereby addressing challenges of current ex vivo genetic medicine approaches, creating new market opportunities, and significantly expanding access for patients.”

Generation Bio’s novel, proprietary cell-targeted lipid nanoparticle (ctLNP) delivery system is engineered to have an extended half-life in systemic circulation compared to current LNP technologies that enables the biologic targeting ligands on the company’s ctLNPs to engage with receptors on specific cell types and tissues to achieve selective, potent, and efficient cargo expression. ctLNPs can deliver a variety of cargos, including Generation Bio’s proprietary immune-quiet form of DNA (iqDNA). iqDNA is designed to express or replace large genes to achieve years-long expression of therapeutic proteins. Generation Bio is focused on developing a range of differentiated, redosable therapeutics: in vivo T cell therapies for autoimmune indications, in vivo hematopoietic stem cells (HSC) therapies for sickle cell disease and beta-thalassemia, and systemic delivery to the liver for hemophilia A.

Second Quarter 2024 Financial Results

• Cash Position: Cash, cash equivalents, and marketable securities were $216.9 million as of June 30, 2024, compared to $264.4 million in cash, cash equivalents, and marketable securities as of December 31, 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.
