- Oral presentation at ASGCT described selective, high levels of therapeutic transgene delivery to T cells in vivo by cell-targeted lipid nanoparticle (ctLNP)
- ASGCT poster presentations described immune-quiet DNA (iqDNA) as partially single-stranded, produced by flexible, scalable, proprietary rapid enzymatic synthesis
- Cash balance of $233.9 million still expected to fund operations into 2H 2027
Generation Bio Co . (Nasdaq: GBIO), a biotechnology company innovating genetic medicines for people living with rare and prevalent diseases, reported additional data on its cell-targeted lipid nanoparticle (ctLNP) platform presented at the American Society of Gene and Cell Therapy (ASGCT) 27th Annual Meeting as well as first quarter 2024 financial results. "The data presented on our ctLNP and iqDNA platforms highlight their maturity and differentiation as the foundation for building programs in hematology," said Geoff McDonough, M.D., chief executive officer of Generation Bio. "Our unique non-viral delivery and cargo may unlock a series of non-viral in vivo therapeutic candidates, starting with sickle cell disease and hemophilia A. We believe our medicines could have a drug-like, redosable in vivo profile, meaning they can surpass what is possible for current viral, biologic and ex vivo approaches to reach people on a global scale."
Recent Highlights:
- Presented New Data Demonstrating In Vivo Delivery of a Therapeutic Transgene to T cells with ctLNP : During an oral presentation at ASGCT, Generation Bio discussed in vivo data demonstrating selective delivery of a T cell-targeted ctLNP carrying mRNA cargo encoding a CAR. In these studies, CAR expression was efficient and dose-dependent with robust surface presentation on T cells. Transduced CAR T cells demonstrated preliminary efficacy in an in vitro tumor cell killing assay. The data were generated as part of the company's collaboration with Moderna, Inc.
Generation Bio has engineered its ctLNPs to avoid clearance by the liver and spleen, allowing selective targeting of tissues and cell types with the addition of a receptor-specific targeting ligand. The next steps for the platform include assessing efficacy in mouse disease models and evaluating the delivery of immune-quiet DNA (iqDNA) with T cell ctLNPs.
The company is also developing a ctLNP targeting hematopoietic stem cells (HSCs) as part of its sickle cell disease and beta-thalassemia program . At ASGCT, the company showed preliminary data demonstrating selective uptake and expression in human HSCs delivered by an HSC-targeted ctLNP.
"The demonstration of selective delivery with a therapeutic cargo outside the liver is an important proof point for the ability of our ctLNPs to reach previously unreachable cell types and tissues," said Phillip Samayoa, Ph.D., chief strategy officer of Generation Bio. "We look forward to advancing our ctLNP platform in T cells and continuing to expand the application into other cell types, beginning with a wholly-owned program in sickle cell disease and beta-thalassemia."
- Disclosed New Information About iqDNA Platform and RES : Also at ASGCT, Generation Bio described its iqDNA as a modified, structured, partially single-stranded DNA that is non-immunogenic while remaining transcriptionally active. The company invented iqDNA using its proprietary rapid enzymatic synthesis (RES) method. RES is a cell-free process that allows for precise chemical and structural changes to DNA. This high degree of control enables the enhancement of DNA functionality by engineering molecular design and components.
Generation Bio is advancing its iqDNA platform with the application of RES. The findings presented at ASGCT demonstrated that a second generation of iqDNA achieved greater luciferase expression than a first-generation iqDNA. The company is currently testing formulations of iqDNA encoding Factor VIII delivered by LNP.
First Quarter 2024 Financial Results
- Cash Position : Cash, cash equivalents, and marketable securities were $233.9 million as of March 31, 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 $10.4 million for the quarter ended March 31, 2024, compared to $12.9 million for the quarter ended March 31, 2023.
- Loss on lease termination : During the three months ended March 31, 2024, we recognized a non-cash charge of $56.9 million in connection with the termination of the Seyon Lease.
- Net Loss: Net loss was $74.5 million, or $1.12 basic and diluted net loss per share, for the quarter ended March 31, 2024, compared to a net loss of $ 32.1 million, or $0.53 basic and diluted net loss per share, for the quarter ended March 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.
